studentPublicationsH1 Peder Berne author Prof Lennart Thörnqvist supervisor Department of Energy Sciences v1000205 department Sammanfattning<br /> Alltmedan miljödebatten får större utrymme i media, har efterfrågan på miljöklassificerade<br /> energiprodukter ökat. Miljöklassificeringar för elprodukter är etablerade sedan en tid tillbaka<br /> och erbjuds i olika kommersialiserade varianter. Miljöklassificeringar av fjärvärmeleveranser<br /> är däremot inte lika etablerat. Den senaste tiden har fjärrvärmeleverantörerna mött en ökad<br /> kundefterfrågan på miljöklassificerade fjärrvärmeleveranser. Kundefterfrågan har framförallt<br /> varit tydlig från företagskunderna och fjärrvärmeleverantörerna har mött denna efterfrågan på<br /> olika sätt. En del har valt att tillämpa Naturskyddsföreningens märkning Bra Miljöval medan<br /> andra har valt sina egna definitioner på en miljöklassificerad fjärrvärmeleverans.<br /> Syftet med detta examensarbete är dels att belysa metoderna för att miljöklassificera en<br /> fjärrvärmeleverans. Jag kommer även att diskutera de märkningar som finns tillgängliga på<br /> marknaden. Huruvida en produkt är miljövänlig eller ej kan vara svårt att definiera och en<br /> möjlighet är att utnyttja en extern märkning. För fjärrvärme är det framförallt återvunnen<br /> energi, förbränning av förnybara bränslen och till viss del värmepumpar som kan användas<br /> för att klassificera en fjärrvärmeleverans som miljöanpassad.<br /> I examensarbetet presenteras de dimensioner av en miljöenergiprodukt, som enligt mitt<br /> förarbete skulle kunna vara de primära för den företagsekonomiska nyttan. Dessa dimensioner<br /> används för att utvärdera nyttan av ett antal av de produktdefinitioner som redovisas i<br /> rapporten. Dimensionerna som utvärderas är ”Varumärket”, ”Intressentkrav”,<br /> ”Miljöpåverkan”, ”Differentiering” och ”Ekonomi”. Det är av betydelse hur miljöenergiprodukten<br /> påverkar företagets varumärke och image. Detta gäller både företaget som<br /> erbjuder produkten och kunden ifråga. Av betydelse är även huruvida produkten underlättar<br /> att uppfylla de krav som ägare, samhället, myndigheter och kunder ställer. Produkten bör även<br /> stämma överens med energibolagets policys, mål och strategier. Vid utvärdering av<br /> företagsekonomiska nyttan är en produkts miljöpåverkan främst intressant ur ett<br /> trovärdighetsperspektiv. Om det är svårt att visa en miljövinst associerad till produkten är det<br /> även svårt att argumentera för produkten eller att ta ut en extra avgift för den. Ytterligare en<br /> viktig aspekt hos en energimiljöprodukt är om den innebär någon form av differentiering,<br /> vilket gäller både för energibolagen och energibolagens kunder. Att ha miljöanpassade eller<br /> miljömärkta produkter kan vara nödvändigt för att inte tappa marknadsandelar och kan<br /> samtidigt vara ett sätt att öka dessa, i synnerhet om produkten är exklusiv. Den ekonomiska<br /> dimensionen är av betydelse när produkten kommuniceras till ledningar, styrelser eller andra<br /> beslutsfattande instanser. Det är viktigt att översätta miljöaspekterna associerade till<br /> produkten i ekonomisk terminologi. Att prioritera vilka åtgärder eller produkter företaget ska<br /> satsa på inbegriper mer än bara miljöaspekterna. Någon form av kostnads- och<br /> nyttobedömning bör göras. Det kan dock vara svårt att värdera olika nyttor som inte direkt går<br /> att mäta i ren ekonomisk vinning.<br /> Förutsättningarna för energibolagen att differentiera sig avseende miljö inom sitt avgränsade<br /> distributionsnät påverkas av hur produktionen av värme till nätet sker. Andelen förnybart<br /> biobränsle i den svenska fjärrvärmeproduktionen har ökat vilket är en följd av att energibolagen<br /> konverterar från fossila bränslen till förnybara. Om det inte finns några möjligheter<br /> att miljöklassificera hela nätet genom till exempel bränslemixen, så kan en viss del av<br /> leveransen i nätet märkas genom allokering, eller så kan fjärvärmebolaget kompensera för<br /> utsläppen. Allokeringar avser i sammanhanget att en del av befintlig produktionsmix bryts ut<br /> och klassificeras som en egen produkt. Att definiera en energiprodukt som miljöanpassad<br /> genom kompensation kan göras på olika sätt. Det mest etablerade alternativet för att<br /> 8<br /> kompensera växthusutsläpp är att utnyttja CDM (Clean Development Mechanism) systemet<br /> genom att köpa och kompensera med CER (Certified Emission Reductions).<br /> Naturskyddsföreningen (SNF) tillhandahåller märkningen Bra Miljöval. Märkningen är<br /> tillämpningsbar på en rad produkter inom olika områden. Den är väl etablerad och nyligen<br /> utarbetade SNF kriterier för att kunna Bra Miljövalsmärka värmeleveranser. Både<br /> allokeringsprodukten och Bra Miljövalsprodukten kräver någon form av allokering inom<br /> aktuellt nät så länge inte hela leveransen uppfyller kraven för produkten. Detta innebär två<br /> parallella produkter, där den ena får ett sämre miljövärde. På elnätet är det etablerat att sälja<br /> parallella produkter på samma nät, vilket tycks fungera. Om så även är fallet för fjärrvärme<br /> har allokeringslösningen potential att få genomslag.<br /> Utifrån analysen av produktdefinitionerna är märkningen Bra Miljöval Värme den som ger<br /> mest företagsekonomisk nytta. Utvärderingen tar dock inte hänsyn till om en fjärrvärmeleverantör<br /> värdesätter de olika dimensionerna olika mycket. Ur fjärvärmeleverantörens<br /> perspektiv får Bra Miljöval Värme högst nytta för dimensionerna ”Varumärket”,<br /> ”Intressentkrav” och ”Miljö” medan Kompensationsprodukten får högst värdering för<br /> dimensionen ”Differentiering” och allokeringsprodukten får högst värdering för dimensionen<br /> ”Ekonomi”. Allokeringsprodukten får även en hög värdering för dimensionen<br /> ”Intressentkrav”.<br /> Många kunder efterfrågar miljöprodukter och om ett energibolag inte följer upp den ökade<br /> efterfrågan finns risken att tappa volym till konkurrenter. Jag tror att en satsning på en<br /> miljöprodukt, som tar ett brett grepp kring problematiken är mer långsiktigt säkert och ett bra<br /> sätt för ett energibolag att differentiera sig på. En produkt med egenskapen att dess miljövinst<br /> går att kommunicera på ett trovärdigt sätt har en rad fördelar.<br /> Jag tror det finns mycket att vinna på att hinna före konkurrenter och vinna marknadsandelar<br /> och stärka sitt varumärke genom att ligga i fronten för miljöarbetet inom branschen snarare än<br /> att avvaktande se vad andra gör. Om ett energibolag vill följa denna linje bör de erbjuda<br /> produkter som inte är uddlösa utan faktiskt gör någon skillnad. Om ett energibolag ska ta en<br /> position som ett innovativt och proaktivt företag med en tydlig miljöprofil finns belägg för<br /> hypotesen att denna strävan bör ske långsiktigt. Oavsett vilken strategi företaget väljer inom<br /> ramen för ett proaktivt förhållningssätt så tycks det till stor del handla om att förbereda sig<br /> inför framtiden. Ju mer förberett och rätt i tiden ett företag är, desto bättre rustat är företaget<br /> för att möta nya strategiska utmaningar.<br /> Utifrån de produktdefinitioner som presenterats tror jag att Kompensationsprodukten och<br /> Allokeringsprodukten är de mest troliga på marknaden idag. Av dessa två tror jag att fler<br /> energibolag väljer att utnyttja allokering, då detta är det mest kostnadseffektiva. För externa<br /> märkningar tror jag att Bra Miljöval Värme kommer att ha genomslag på marknaden.<br /> Benämningen ”Klimatneutral” är en stark utfästelse och är svår att argumentera för. Det är<br /> inte troligt att en fjärrvärmeprodukt med benämningen ”Klimatneutral” kommer att kunna<br /> leva upp till de krav som ställs enligt marknadsföringslagen och Internationella<br /> handelskammaren. Det kan således förefalla vara mer strategiskt att ha produktens verkliga<br /> och utmärkande egenskaper i fokus vid val av benämning. https://lup.lub.lu.se/student-papers/record/1423513/file/1423770.pdf application/pdf 926372 no 2009 swe fjärrvärmeprodukt miljöklassificering Technology and Engineering 1423513 2009-06-16T13:29:17+02:00 2009-06-23T10:38:26+02:00 2009-06-23T10:38:26+02:00

VEKS is a transmission<br /> company supplying heat in western Copenhagen, Denmark.<br /> VEKS wanted a global analysis over the possibilities to decrease the cost<br /> and carbon dioxide emissions from purchased heat through decentralized<br /> accumulation.<br /> To cover all economical and environmental reasons for accumulation, four<br /> posts were analyzed. The four posts included were: reducing the peak‐load,<br /> optimization of base‐load, analyzing variation in heat load and existing<br /> accumulators and finally simulations with optimization tools.<br /> The conclusion was that it takes at least a 60 MWh accumulator with a<br /> capacity of 15 MW to lower the load factor in the north section of VEKS<br /> transmission network. The storage volume has to be 1 150 cubic meters<br /> with a height on 18.5 meters and a diameter of 8.9 meters.<br /> It is not profitable for VEKS to invest in a decentralized accumulator. The<br /> payback time is 12 years without taking the interest into account. If the<br /> interest is taking into account, the investment never pays off. The total<br /> reduced cost for purchased heat was estimated to 900 thousands Danish<br /> kronor with 420 tonnes of reduced carbon dioxide emissions annually.<br /> The local CHP‐plant Avedøre has an accumulator with a storage volume of<br /> 2 600 MWh. Instead of investing in a decentralized accumulator it would<br /> be wise to use the existing Avedøre accumulators more effective.<br /> We have not found any situations where there is need for further<br /> accumulation capacity over 24 hours, thereby we do not exclude the<br /> possibilities that they in fact exists. https://lup.lub.lu.se/student-papers/record/1423676/file/1423799.pdf application/pdf 2513132 no 2008 swe ackumulering fjärrvärmenät Technology and Engineering 1423676 2009-06-16T13:53:43+02:00 2009-06-23T10:39:48+02:00 2009-06-23T10:39:48+02:00

studentPublicationsH1 Eric Månsson author Prof Bengt Sundén supervisor Department of Energy Sciences v1000205 department The intention of this master thesis is to model the internal flow of an Alfa Laval course Filter with 20 cm inlet and normal outlet (ALF20), which is an automatic self cleaning filter aimed to rinse the cooling water upstream the inlet of a compact heat exchanger. Along the automatic cleaning process the ALF20 turn into a flushing and a back flushing operation mode. The ALF20 consists of a filter body, a diverter valve and a filter basket. Three connection tubes where the inlet, the outlet and the flushing outlet pressure were measured were connected and used in the measurement. Two filter baskets were available with different hole diameters and hole area percentage. <br /> Experimental measurements of pressure difference and temperature are done for normal, flushing and back flushing operation modes in the Process Laboratory at Alfa Laval AB in Lund. The measurement considers flow in empty the ALF20 filter house, the empty ALF20 with diverter valve and the ALF20 in full configuration with filter baskets 1 or 2 attached. Alternative cylinders aimed to simulate fouling are attached in further measurements. <br /> The computational fluid dynamics calculation model has been developed and checked while comparing computational results with the measurement tests of the corresponding test cases. <br /> A literature survey is presented covering related topics in basic fluid dynamics, empirical data regarding flow through perforation holes, turbulence and Computational Fluid Dynamics.<br /> Since the radial forces on the filter basket may result in failure, these forces will be evaluated in terms of direction and magnitude at the filter basket surface. <br /> The internal flow geometries of measured ALF20 (CAD drawing received from Alafa Laval A/S. Soeborg) cases are created and meshed for use in the commercial Computational Fluid Dynamics (CFD) software FLUENT. Evaluations are done to determine a grid independent mesh, most suitable turbulence model and the most appropriate inlet velocity boundary condition. <br /> Since, the filter baskets is made of a perforated plate consisting of a large number of holes which not can be represented in the model in detail, a porous medium model is used to represent the perforated areas. Pressure loss coefficients are taken from the literature and are modified according to local kinetic energy and pressure differences over the filter basket surface. Pressure differences and velocities are taken from preliminary CFD simulation using non modified pressure loss coefficient. <br /> All computational results are post processed in FLUENT and presented in the form of velocity path lines, pressure contours and tables. Comparisons with the measured experimental pressure drop are done for all cases and can be found in the result tables. Since the deviation from measured results is moderate, the computational model seems to agree well with the real flow situation. <br /> Radial forces pointing from the outside of the filter basket towards the center seems to occur in the back flushing mode in the rear end of the filter basket. https://lup.lub.lu.se/student-papers/record/1423731/file/1423798.doc application/x-ole-storage 12955136 no 2008 eng self cleaning CFD Simulations filter Technology and Engineering 1423731 2009-06-16T14:19:36+02:00 2009-06-23T10:39:23+02:00 2009-06-23T10:39:23+02:00

studentPublicationsH1 Adrian Dahlquist N author Magnus Genrup supervisor Department of Energy Sciences v1000205 department A brief description of the physical flow phenomena in a blade row that creates losses<br /> in an axial gas turbine and correlations to estimate these losses in a mean line<br /> calculation are given. Investigation and comparison of the loss correlations for 1D<br /> mean line calculation between the in-house program (CTC) used at Siemens and loss<br /> correlations present in the open literature were made. The investigation is primarily<br /> focused on the problems associated with modeling off-design effects on profile and<br /> secondary losses, and the effect of tip leakage losses at all loads. For the off-design<br /> condition both positive and negative flow incidence were covered with internal tests<br /> and numerical 2D investigations. The increase in blade losses at high outlet Mach<br /> number and how it is related to the shape of the suction surface for a blade profile was<br /> investigated with numerical 2D simulation.<br /> The results for the loss models are validated against previous done internal gas turbine<br /> test runs at Siemens, external cascade tests and numerical 2D simulations.<br /> The overall conclusions are that the in-house program (CTC) shows good prediction<br /> ability for the off-design down to the state where the turbine reaches turn-up mode.<br /> But some questions about CTC’s distribution between profile and secondary losses<br /> are discussed.<br /> For the tip leakage loss it was highlighted that CTC shows a somewhat low loss for a<br /> constant clearance and also a rather low increase with relative clearance change. A<br /> limitation in the prediction ability because the absence of some believed important<br /> parameter was also seen and an alternative model was suggested for unshrouded<br /> blades.<br /> It is clear that there for most blade designs is seen a sudden increase in the blade<br /> losses at an outlet Mach number in the region of 0.9. But no obvious relations to<br /> which blade parameters that determine the absolute increase were found https://lup.lub.lu.se/student-papers/record/1423748/file/1423797.pdf application/pdf 2220137 no 2009 eng Loss models axial gas turbines Technology and Engineering 1423748 2009-06-16T14:30:04+02:00 2009-06-23T10:38:56+02:00 2009-06-23T10:38:56+02:00

studentPublicationsH1 Lehon Hamarashid author Ass Prof Per Tunestål supervisor Department of Energy Sciences v1000205 department This master thesis has been conducted at the Division of Combustion Engines under the Department of Energy Sciences, Faculty of Engineering at the Lund University. The purpose of this master thesis project is to create a computer based model of a Natural Gas Engine in order to raise its potential for updating a Volvo bus as well as creating a study of the improvement efficiency of the Miller Cycle. In the last 100 years, there has been enormous progress in the internal combustion engine field. The emission of reactive Hydrocarbon from light duty vehicles is approximately. 70 percent lower in natural gas operation than with petrol operation. Emissions of greenhouse gases are 15-25 percent lower with in natural gas operation than from corresponding petrol vehicles. Environmental improvement by reducing emissions as well as alternative energy issues will become more and more important in the future. Diesel engines have a higher efficiency level compared to gasoline engines, but the problem is that their NOx and Soot emissions are higher than other types of engines. That’s one of the main reasons why Natural Gas engines became more and more important over the last few years. New gas buses that are run with vehicle gas emit approximately 50% less NOx than corresponding diesel buses, something that can to contribute substantially to creating better air environment in the big towns. Moreover, the emission is reduced of carcinogenic pollutants and particles. [1] The gas engine project at Lund University is exploring the extension of the performance, fuel efficiency and the stability of a spark ignition (SI) natural gas engine. The engine is a partly modified (modified from a single point to multi-port injection system), 6-cylinder turbocharged (9.4 liter) Volvo engine, which is equipped with EGR valves and an EGR cooler. The engine runs on a Stoichiometric mixture of air and fuel associated with the cost effective 3-way after treatment system. The work presented in this thesis has focused on studying, with simulation, an engine model for new gas buses that is run with natural gas and a study with Miller Cycle. This research has been conducted in a 1-D gas exchange simulation program called GT-Power with an engine model originating from VOLVO. As well, during the verification of this model, testing cases were modified to produce different tests. https://lup.lub.lu.se/student-papers/record/1429536/file/1429537.pdf application/pdf 1368994 no 2008 eng Miller Cycle GT-Power Modeling Natural Gas Engine Technology and Engineering 1429536 2009-06-23T10:28:30+02:00 2009-06-23T10:40:13+02:00 2009-06-23T10:40:13+02:00

A<br /> survey of the energy use and how to decrease the energy use was carried out. The first<br /> part is about snow and snowmaking.<br /> Natural snow consists of water molecules that form a hexagonal pattern in solid state.<br /> The reason to the hexagonal pattern is due to dendritic growth during the snow<br /> crystals journey through the cloud towards the ground. Snow from snow guns is<br /> spherical in shape in contrast to natural snow, which has a hexagonal pattern.<br /> Depending on the type of snow gun that is used different amount of snow is produced<br /> depending on the wet bulb temperature. With the current modern snow guns the snow<br /> quality is not dependent on the temperature instead the amount of snow produced<br /> increases with decreasing temperature.<br /> The foundation Idre Fjäll is the second largest ski resort company in Sweden if<br /> turnover is counted. Approximately 15 GWh is used during one year, 3 GWh or 20 %<br /> is used to produce snow.

California is a state with considerable meteorological and hydrological diversity, meanwhile with a total capacity of 14116 MW of 386 hydroelectricity generation units with capacity larger than 0.1 MW, California is the USA’s second largest state on hydropower. For such a giant hydropower state, prediction of hydropower generation could yield big profit in the energy market, and the well developed Scania-HBV makes this prediction possible. However, as a conceptual model, Scania-HBV has to be adapted for individual situation, and thus model calibration and validation are compulsory for a reliable prediction. Meteorological and hydrological data together with generation data from 1981 to 2006 were collected, and used for calibration and validation of the model. The state was divided into three sub-regions that were modeled individually. https://lup.lub.lu.se/student-papers/record/1365536/file/1384346.pdf application/pdf 2050203 no 2009 eng hydropower Scania-HBV calibration California Technology and Engineering 1101-9824 08/5013 Examiner: Rolf Larsson 1365536 2009-03-23T19:33:29+01:00 2019-03-27T10:54:19+01:00 2009-04-22T12:16:35+02:00

studentPublicationsH1 Daniel Jarnekrans author Dr Jenny Larfeldt supervisor professor Xue-Song Bai supervisor Department of Energy Sciences v1000205 department The purpose of this Master’s Thesis is to develop a model for numerical simulations in order to kinetically characterize different Medium Calorific- Low Calorific Value (MCV-LCV) fuel gas mixtures. Adding fuel components with a very low heating value or inert species affect the stability of the standard gas turbine combustor design.<br /> Siemens Industrial Turbomachinery (SIT) believes that increasing the fuel flexibility of their current gas turbine combustors is important in maintaining a leading position on the industrial power generation market.<br /> The numerical model development has included a test of chemical reaction mechanisms suitable for modelling syngas co-fired with natural gas. Predictions of laminar flame speed and ignition delay time for various syngas fuel mixtures at different pressures and initial temperatures have been compared to experimental data. Two different reactor models suitable for ignition delay time calculations have also been evaluated. ChemKin is the primary software used in this work but a performance test of the open-source chemical kinetics code package Cantera has also been conducted for comparisons.<br /> An investigation of the global chemical time scale, which is a fuel mixture characteristic, was performed to find a possible correlation with experimental flameout/flameback data from rig tests with a SIT burner. A correlation between the global chemical time and the limit for flameout was found for nitrogen content up to 35% by volume in the natural gas fuel for the AEV LB000 reference burner. For very high inert content in the natural gas fuel additional fluid dynamic effects becomes increasingly important, hence further confirms that the ultimate flameout limit is governed by the flow and the specific burner.<br /> For an arbitrary burner, auto ignition in the burner mixing tube might be relevant for inducing a possible flameback. A general investigation of the ignition delay time scale has therefore been included. The risk of flameback/flashback is known to increase when adding highly diffusive species to the fuel. It is clear that auto ignition may also be a relevant mechanism in inducing/supporting a flameback, given a sufficiently high temperature for ignition. For the LB000 burner standard operating conditions, ignition delay is irrelevant due to low air preheat temperature. Ignition delay time simulations are preferably performed using a homogeneous constant-pressure reactor, determining ignition by the maximum temperature gradient.<br /> Further development of chemical mechanisms suitable for modelling laminar flame speed and ignition delay of syngas-natural gas fuel mixtures at gas turbine operating conditions is required. The laminar flame speed predictions of ChemKin however proved quite accurate for lean mixtures at low preheat temperatures.<br /> The open-source software Cantera has proven to be a flexible code consistently over-predicting the laminar flame speed compared to ChemKin. It is also less user-friendly due to the lack of code documentation and technical support. https://lup.lub.lu.se/student-papers/record/1393089/file/1393107.pdf application/pdf 1815152 no 2007 eng Combustion characteristics fuels kinetics gas turbine conditions Technology and Engineering 1393089 2009-05-05T15:35:53+02:00 2009-06-23T10:40:41+02:00 2009-06-23T10:40:41+02:00

But despite that a desire for good event management may exist, the knowledge may be lacking. This master thesis aims to study the risks and dependencies on LARP events with the goal to answer the question: “What should be included in safety guidelines for LARP events and how should these safety guidelines be designed with regards to how LARP events are conducted today?” The study included a detailed field study of a LARP event where qualitative interviews and a quantitative survey study were conducted. The result show that a LARP event has a number of dependencies and risks that must be addressed in order to ensure that the event is made safe for the participants as well as the organizer. https://lup.lub.lu.se/student-papers/record/4157445/file/4157459.pdf application/pdf 2096297 no 2012 swe Arrangemang arrangemangssäkerhet beroendeanalys beroendehjulet beroenden event lajv lajv-arrangemang lajvarrangör lajvevent levande rollspel risk riskanalys rollspel säkerhet säkerhetsriktlinjer event management event manager event safety dependency analysis interdependency wheel dependencies LARP LARP events LARP organizer live action role playing risk analysis role playing safety safety guidelines Technology and Engineering 1402-3504 5376 4157445 2013-11-18T14:42:33+01:00 2014-03-10T10:40:46+01:00 2013-11-18T14:50:17+01:00

Leading objective indicators of safety are safety culture related <br /> metrics that are statistically correlated with safety performance data which enables a more <br /> proactive approach to safety management. The conclusion was that no indicators could be <br /> identified, at least not across a wide range of different shipping companies from different sectors <br /> due to major differences in safety monitoring and perception of terms and expressions related to <br /> safety. It was therefore concluded that there is a need for a more common understanding of <br /> terms and expressions used within the shipping sector.

studentPublicationsH2 Julien Jaunâtre author 4172868 Professor Magnus Larson supervisor Division of Water Resources Engineering v1000225 department The main purpose of this thesis was to simulate the three-dimensional flow patterns in tanks for water storage. The practical intentions of the simulations were to identify water-quality problems related to insufficient water exchange. The water storage reservoirs at Norra Ugglarp in South Sweden were investigated as a special case study. In this thesis, the open source CFD software OpenFoam was chosen to simulate flow features in tanks. <br /> The first part of this thesis focused on developing an understanding of the case study; that is, the distribution of water in West Skåne and especially the functioning of Norra Ugglarps reservoirs. An overview of possible mixing problems in the tank was detailed and presented. <br /> As modelling was chosen to identify mixing problems, mechanisms and equations about flow modelling were first discussed before going into the OpenFOAM software itself. The modelling strategy in OpenFoam do not differs from other CFD software; nevertheless, setting up the case and post processing the results were quite unusual and discussed in some detail.<br /> When it came to the modelling itself, in order to become familiar with the software, some simple test setups were first explored in two-dimensional tanks of simple geometry. Then, the simulations were extended to three-dimensional situations, still for rectangular tanks. Finally, the software was employed to simulate the flow in the reservoirs at Norra Ugglarp.<br /> From the modelling results, it was possible to derive the following conclusions. The incoming velocity is a key parameter as injection of water should be powerful enough to reach the surface and renew the upper layer water. Water level range is another important parameter to renew more volume in the tanks. All conclusions tend to prove that the reservoirs at Norra Ugglarp suffer from insufficient mixing, mainly due to both the weak incoming velocity of new water and the limited water level range in use.<br /> Thus, solutions to alleviate poor mixing are presented, such as increasing the water level range or monitoring existing valves to ameliorate the filling regarding water circulation. Det huvudsakliga syftet med detta arbete var att simulera tredimensionella flödesmönster i tankar för lagring av vatten. De praktiska avsikter med simuleringarna var att identifiera vattenkvalitetsproblem relaterade till bristande vattenutbyte. De vattenmagasin som reservoarer vid Norra Ugglarp i Skåne utgör undersöktes i en särskild fallstudie. I denna avhandling har den öppna CFD källkoden OpenFOAM valts för att simulera cirkulationen i tankarna.<br /> Den första delen av rapporten fokuserar på en detaljerad förståelse av fallstudien, som omfattar fördelningen av vatten i västra Skåne och särskilt funktionen hos Norra Ugglarps reservoarer. En översikt över möjliga omblandningsproblem i reservoarerna studerades i detalj och sammanfattades.<br /> Modellering valdes för att identifiera omblandningsproblem samt grundläggande mekanismer och ekvationer för flödesmodelleringen diskuteras först innan man går in på själva programvaran OpenFOAM. Modelleringsstrategin i OpenFOAM skiljer sig inte nämnvärt från annan CFD-programvara, även om upprättandet av det studerade fallet och efterbearbetningen av resultaten var ganska ovanligt, vilket speciellt diskuteras i rapporten.<br /> Vad gäller själva modelleringen, för att bli bekant med programmet, har några enkla testuppställningar först utforskats omfattande två-dimensionella tankar av enkel geometri. Därefter utsträcktes simuleringarna till tre-dimensionella situationer för rektangulära tankar. Slutligen användes programvaran för att simulera flödet i Norra Ugglarps reservoarer.<br /> Från modelleringsresultaten var det möjligt att erhålla följande slutsatser. Hastigheten hos den inkommande strålen är en viktig parameter och den bör vara tillräckligt hög så att strålen kan nå ytan och förnya övre vattenskikt. Variationen i vattennivå är en annan viktig parameter för att förnya volymen i tankarna. Resultaten från föreliggande beräkningar visar att Norra Ugglarps reservoirer lider av dålig omblandning, främst på grund av den låga hastigheten hos den inkommande strålen av nytt vatten och den begränsade variationen i vattennivå.<br /> Lösningar för att förbättra omblandningen presenteras, till exempel att öka variationen i vattennivå och att övervaka befintliga ventiler för att förbättra fyllningsprocessen med avseende på vattencirkulationen. https://lup.lub.lu.se/student-papers/record/4172871/file/4172872.pdf application/pdf 3873213 no 2013 eng drinking water storage tank rectangular tank Computational Fluid Dynamics (CFD) numerical modelling 2D 3D flow cluster Lunarc dricksvatten ackumulatortank rektangulär tank numerisk modellering 3D flöde kluster Lunarc.

A common complement is finding the root of an algebraic function (an event function) that depends on the states of the problem. This formulation of a model enables the possibility of including discontinuities and saving or stopping the process more effective. The problem of root-finding during integration is however difficult. Both in a theoretical aspect and as a software problem. In this thesis, the theoretical aspects are made with emphasis on explicit ordinary differential equations and the implementation of software is done in Assimulo. It takes into consideration the existing structures and the Functional Mockup Interface standard. The implementation is made usable for a wide variety of solvers and is also verified and benchmarked with advanced industrial models, showing good indications of being robust and scaling well for large systems. https://lup.lub.lu.se/student-papers/record/4173087/file/4173093.pdf application/pdf 693407 LU/LTH access 2013 eng ODE DAE event Assimulo JModelica Discontinuities FMI Functional Mockup Interface differential equations Root-finding safeguard Technology and Engineering 1404-6342 2013:E38 LUTFMA-3024-2013 4173087 2013-11-20T12:55:40+01:00 2024-10-18T16:29:48+02:00 2014-02-14T16:26:55+01:00

Condition based maintenance is about maintaining the correct equipment at the right time. CBM is based on using real-time data to prioritize and optimize maintenance resources. The main point is that the condition of the equipment is assessed during operation to determine whether it is in need of maintenance or not. If so, at what time should the maintenance actions be executed to avoid a breakdown or a malfunction? The frequency for CBM can thus be dynamic. To really utilize CBM in the most efficient way is to use machine integrated systems with sensors, data collection, monitoring, diagnosis and prognosis. https://lup.lub.lu.se/student-papers/record/4173940/file/8961707.pdf application/pdf 1365776 no 2013 swe tillståndsbaserat underhåll vibrationsmätning underhåll underhållsstrategi driftsäkerhet Technology and Engineering 4173940 2013-11-20T00:00:00+01:00 2018-10-18T10:28:09+02:00 2013-11-22T00:00:00+01:00

It is often profitable to continue using an aging platform instead of deploying a new one. A common practice in quantitative risk analyses performed on aging platforms is to use constant failure rates for components and ignore a potential aging effect. This thesis intends to examine how failure rates of components change on aging platforms, how component maintenance can be incorporated in risk analyses and how the location specific fatal accident rate (LSFAR) is affected by aging. A simplified platform is defined and an analytical model on aging is developed. The model includes renewal and surveillance intervals and the failure rate increase due to aging. Together with a consequence analysis, the model yields LSFAR due to hydrocarbon releases. Calculations of LSFAR carried out with and without consideration of aging are compared. The results show that LSFAR increases at most 1 %. Thus, the practice of using constant failure rates on aging platforms cannot be rejected. Because the results are based on interpolated failure data, it is associated with uncertainties. To reduce these uncertainties, case specific data should be gathered. https://lup.lub.lu.se/student-papers/record/4174736/file/4174737.pdf application/pdf 2779423 no 2013 eng Aging failure rates FAR gas maintenance surveillance offshore oil production platform QRA renewal risk analysis unreliability åldrande felfrekvenser underhåll tillsyn olja produktionsplattform utbyte riskanalys otillförlitlighet Technology and Engineering 1402-3504 5429 4174736 2013-11-25T10:30:48+01:00 2014-03-10T10:40:46+01:00 2013-11-25T10:38:12+01:00

One part of this legislation demands that all business that handle certain amounts of chemical compounds to submit a safety report in order to get permission to run their business. <br /> The safety report should contain over-all plans of how to handle safety as well as detailed descriptions of several accident scenarios. If one wants to build a new chemical facility the safety report is supposed to be handed in when applying for a permit to run the operation. This often has to be done long in advance. The problem that this report focuses on is how to develop a safety report when you don’t know how the facility will look or operate. By examining and interpreting the legislation and conducting interviews with representatives from agencies and companies a possible solution is presented. The proposed solution is to produce a safety report in two steps. In the first step a preliminary safety report is developed and sent in to the authorities. The second is to continue to develop the safety report as planning and building progresses and more data about the facility becomes known. This way you can present a safety report in an early stage but one still have the opportunity to improve the safety report as information becomes available. One important part of this report is the attempt to find a minimum level of the information in a safety report. To know this is important to companies to make the application process more predictable and clear. It is important to remember to not stop the work on the safety report if step one gets accepted by the authorities, the safety could be at risk if one does not continue the work with the safety report. https://lup.lub.lu.se/student-papers/record/4174860/file/4175217.pdf application/pdf 1239079 no 2013 swe Seveso säkerhetsrapport kemikalieolyckor safety report chemical accidents Technology and Engineering 1402-3504 5425 4174860 2013-11-25T11:40:20+01:00 2014-03-10T10:40:46+01:00 2013-11-26T11:21:56+01:00

studentPublicationsM1 Fabian Unghanse author 4175204 Hoda Davarzani supervisor Engineering Logistics v1000260 department Background: Theory of warehouse operation are a well explored area but it seems that warehouse manager have a hard time to understand what solutions to adapt to improve their warehouse. Theory of Constraints(ToC) are a young philosophy regarding improvements work that have been employed to many different business areas. Warehouse manager would need a method to evaluate what solutions to implement to the warehouse and there is no found papers where ToC is employed to facilitate this evaluation.<br /> <br /> Purpose: The purpose is to see if ToC can be employed for improvements work in a warehouse. At the same time the three research question should be answered to clarify what approaches and tools within ToC to use for different part of the improvements work.<br /> <br /> Problem definition: To know if ToC can be employed in a warehouse operation a case study was executed. The company in the case study have a warehouse that faces challenges in the near future due to increase sale and that the warehouse maximum capacity almost is reached, for how it operate today. The warehouse have low level of strategies. The warehouse have to get more effective and efficient to be able to maintain the service level in the future.<br /> <br /> Method: Warehouse operation have been studied at the university and a high level of knowledge in that field exist but low level of knowledge for ToC exist. The project will therefore start by studying ToC so it later can be successfully employed in the warehouse operation in the case study.<br /> <br /> Conclusions: From the case study it is clear that ToC could be employed for improvements work for wear house operations. By following the approach provided by ToC the work could be carried out in an efficient way. It was identified which tools that was appropriate to use for different parts of the improvements work. https://lup.lub.lu.se/student-papers/record/4175198/file/4175199.pdf application/pdf 8756301 no 2013 eng ToC TP CRT EC FRT PRT TT Harald Phil Warehouse Operation focusing steps Technology and Engineering https://lup.lub.lu.se/student-papers/record/4175198/file/4175203.pdf application/pdf no 4175198 2013-11-26T10:32:18+01:00 2013-11-26T10:52:08+01:00 2013-11-26T10:52:08+01:00

studentPublicationsM1 Viktor Reutherborg author 4175226 Fredrik Friblick supervisor Engineering Logistics v1000260 department Problemformulering: Hur ser informationsflödet mellan leverantör och entreprenör ut och vilka icke värdeskapande aktiviteter finns idag kopplade till en bristfällig leveransplanering? Kan dessa aktiviteter reduceras med befintligt systemet eller finns önskemål att ändra eller ta fram en helt annan typ av system?<br /> <br /> Syfte: Att ge läsaren en god inblick i hur det arbetars med materialförsörjning på en byggarbetsplats och aktiviteter som rör detta. Rapporten ska tydliggöra ifall leveranssystemet är bra, behöver förbättras eller förkastas helt.<br /> <br /> Metod: Studien kommer genomföras som en kartläggning och två fallstudier. Dagsläget kartläggs genom kvalitativa studier med sin grund i intervjuer med leverantörer, platschefer och logistikansvariga. Två pilotprojekt som använder sig av leveransplaneringssystemet kommer att utvärderas på ett kvalitativt sätt genom två fallstudier med sin grund i intervjuer och observationer. En av fallstudierna sker som en aktionsstudie där författaren själv arbetar med ett system för leveransplanering.<br /> <br /> Målgrupp: Målgruppen för studien är de företagen som är inblandande i försörjningskedjan till en byggarbetsplats. Inte endast NCC Construction utan även leverantörer samt transportföretag. Olivetree, som tar fram systemet, är även de en målgrupp då de genom studien får feedback på sitt system. Det kan tänkas att även konkurrenter till NCC kommer att vara intresserade samt personer som studerar logistik i byggbranschen. <br /> <br /> Slutsats: Det finns behov av att ändra tillvägagångssätt för leveransprocessen för både sortimentsinköp och projektinköp. Ett steg i rätt riktning är att strukturera upp informationen mellan entreprenör och leverantör. Idag finns det ingen genomgående struktur på informationen som beaktar leveransplanering. För sortimentsinköp sker leveransen enligt förutbestämda avtal och projektinköp genom Exceldokument som e-postas mellan entreprenör och leverantör. Detta gör att leveransplaneringen blir ineffektiv. Systemet beaktar<br /> detta då det finns en funktion där leveransplaner skapas. I leveransplanerna skapas leveransdelar med innehåll och bestämt leveransdatum. Leveransplanerna gör att risken för missförstånd minskar kraftigt då det bara finns en leveransplan som uppdateras direkt och den tidigare versionen försvinner. Av leveransdelarna skapas kolli. Ett kolli har en bestämd slutdestination,<br /> märks tydligt och när materialet kommer till arbetsplatsen lyfts det direkt till rätt position på bygget för att minska icke värdeskapande aktiviteter och materialspill. Leveransplanerna är idag inte ihopkopplade med inköpssystemet samt leverantörens system vilket önskas i framtiden för att ytterligare effektivisera processen. Det sker väldigt många leveranser till byggarbetsplatser och ofta finns det ingen direkt plan för materialet. Om det är en trång arbetsplats kan det också vara svårt att planera leveranserna för att de inte ska kollidera. Systemet innehåller en leveranskalender där arbetsledare och underentreprenören kan boka tider for lossning. I kalendern bokas en tid kopplad till en lossningszon och resurs. Genom kalendern undviks att<br /> leveranser kollisiderar och genom att visa kalendern får alla en bra bild av när material kommer och hur produktionen kommer se ut under veckan. Problem: This study examines problems in the Construction supply chain. Most industries have already included use of assistive technology in their daily work and I will research if it is possible to implement a system for delivery planning in the construction industry to reduce non-value adding activities. A system designed for construction delivery planning has been developed. In order to grow an understanding of the system two pilot projects were examined and evaluated.<br /> <br /> Purpose: The purpose of this paper is to describe existing delivery methods and to answer if a delivery system can be implemented to improve the delivery process.<br /> <br /> Method: Primary data was collected through interviews to establish a broad perception of the current situation on a construction site. In order to get a deeper understanding of the situation quantitative interviews were held with suppliers, site managers and logistics managers. Two case studies of projects currently using the system was investigated by interviews and action research.<br /> <br /> Target Group: The target groups for this study are the companies that are involved in the construction supply chain. For the scope of the thesis NCC has been the main target group. Suppliers and carriers can improve their value chains in order to know the strength and weaknesses of the system. The supplier of the software, Olivetree will also get feedback on their system and how it is currently working in practice. Competitors to NCC can also be seen as a target group as well as everyone with a passion for logistics in the construction industry.<br /> <br /> Conclusion: There is a need to change the delivery process for both assortment purchases and project purchases. There is currently no structured way to work with delivery planning. Assortment purchases are delivered according to predetermined agreements and project purchases through excel documents, mailed between Contractor and suppliers. This results in an ineffective delivery planning. The developed system contains a feature where delivery schedules are created. Delivery packages with determined content and delivery dates can be created and scheduled in an easy way reducing the possibility of delivery plans getting mixed up. This problem will be excluded since there is only one delivery plan, which is being updated immediately if a change is made. Each delivery package has a definite final destination, and has a unique label that makes it possible to locate the correct position upon arrival. As a result of accurate placement on the construction site, cost related to reduce non-value adding activities and material waste are minimized. Delivery plans are not currently paired with the purchasing system and supplier systems. This is desired in the future to further develop the process. There are many deliveries to a construction site during a project and there is often no drawn strategy how to place the material when arriving. A crowded workplace creates difficulties in the delivery planning process. Without a delivering system double bookings are common. The system includes a delivery calendar that supervisors and subcontractor can use to make an unloading reservation. To make reservation in the calendar every reservation is connected to an unloading zone and a resource. The calendar avoids delivery collisions and supplies a good view of when materials will arrive. https://lup.lub.lu.se/student-papers/record/4175210/file/4175223.pdf application/pdf 4852393 no 2013 swe Varuförsörjningsprocessen leveranskalender leveranssystem byggbranschen informationsflöde leveransplan automatisering construction Supply Chain delivery calendar delivery system information flow delivery process atomization Technology and Engineering https://lup.lub.lu.se/student-papers/record/4175210/file/4175225.pdf application/pdf no 4175210 2013-11-26T11:15:10+01:00 2013-11-26T12:33:55+01:00 2013-11-26T12:33:55+01:00

studentPublicationsM1 Henrik Andersson author 4175253 Herman Persson author 4175254 Jan Olhager supervisor Engineering Logistics v1000260 department Bakgrund: Trioplast Landskrona tillverkar och trycker plastmaterial till förpackningar. Med en prispressad marknad så upplever företaget att de har svårt att konkurrera med andra företag belagda i lågavlönade länder. Priser är pressade till nivåer där Trioplast Landskrona har svårt att konkurrera med den verksamhet som bedrivs idag, Därmed vill företaget rikta sig mot den delen av marknaden som ställer högre krav på flexibilitet, miljövänlighet eller ett nära samarbete. Företagets förändrade marknadsinriktning har även ställt nya krav på hur övriga verksamheten bedrivs, framförallt produktionsavdelningen som gått från linjeproduktion till batchproduktion. Detta skifte ställer nya krav på effektiviseringar men även närmre samarbete internt inom verksamheten.<br /> <br /> Syfte: Syftet med examensarbetet är att utveckla företagets planerings- och styrsystem.<br /> <br /> Målsättning: <br /> • Skapa ett verkställande och fortlöpande planerings- och styrsystem<br /> o Fördela ansvaret i planeringen<br /> o Stärk kommunikation över funktionsgränserna<br /> • Skapa regler för att systematisera arbetet för samtliga avdelningar<br /> <br /> Metod: Det övergripande syftet med detta examensarbete är av problemlösande karaktär, att givet formulerade problem beskriva dess ursprung och hur dessa kan lösas. Därmed faller examensarbetes val av arbetssätt på aktionsforskning vilken bygger på att förbättringar sker under tiden som fenomenet utforskas. Aktionsforskning använder sig av ett liknande resonemang som det abduktiva angreppssättet, vilket gör det naturligt att beskriva detta examensarbetes angreppssätt som abduktivt. Genom en kontinuerlig teoribildning kunna beskriva och analysera empiri, för att slutligen skapa ett förslag grundat i teorier. Den praktiska arbetsgången beskriver vi vilken ordning de olika delarna i arbetet sker. Dessa sker enligt följande punkter:<br /> 1) Studera företagets affärsplan<br /> 2) Granska operationell verksamhet med koppling till problemformulering<br /> 3) Kartlägga befintligt planerings- och styrsystem<br /> 4) Utveckla ett börläge<br /> 5) Exemplifiera genom ett praktikfall<br /> <br /> Slutsats: Trioplast Landskrona ska utveckla ett hierarkiskt planerings- och styrsystem bestående av fyra planeringsnivåer. Detta ska grundas i företagets affärsplan och sedan koppla samman företagets affärsplan med dess operationella verksamhet. De fyra planeringsnivåerna kallas sälj- och verksamhetsplanering, huvudplanering, behovsplanering och detaljplanering. För att utveckla detta nya system ifrån deras system så ska Trioplast Landskronas planeringsmöten utvecklas till en sälj- och verksamhetsplaneringsprocess med ett avslutande beslutsmöte. Planeringshierarkin ska framöver innefatta en huvudplanering som drivs av företagets planeringschef och som inkluderar ett nytt informativt huvudplaneringsmöte. Slutligen ska företagets detaljplaneringsarbete bedrivas utifrån företagets nyinrättade produktfamiljer där de två planerarna planerar olika produktfamiljer, istället för olika avdelningar i produktionsavdelningen. Background: Trioplast Landskrona manufacture and print plastic packing material. As the market pressures the prices down, the company feels that they are having a hard time competing with other companies from low salary countries. The margins are so low on the current market, that it is hard for Trioplast Landskrona to be profitable. Therefore, the company want to focus on a new market segment that valuates higher flexibility, environmental friendly products or a closer collaboration. With this new offer, new and different requirements are put on the other parts of the business. Especially on the production department, which has moved from being line production to become batch production. These changes has demands of improvements, but also a closer collaborations and communication within the company.<br /> <br /> Purpose: The purpose of this master thesis is to develop the company planning and control system.<br /> <br /> Objectives: <br /> • Create an executive and on-going planning and control system<br /> o Define a clear structure for the planning process<br /> o Distribute responsibility in planning<br /> o Strengthen communication across the functional barriers<br /> • Create rules to systemize work for all affected departments<br /> <br /> Method: The method of this master&#39;s thesis is of problem solving character; from formulated problems describe its origin and how these could be solved. Thereby, the choice of research method for this master thesis is “action research”, which builds on the continuous improvements while studying the phenomenon. “Action research” uses the same kind of reasoning as the abductive approach, which makes it naturally to describe this master thesis approach as abductive. By continuously reviewing theories being able to describe and analyse empiric<br /> acknowledges, to finally create a result based on theory. Following, the practical method is described:<br /> 1) Study the company business plan<br /> 2) Review operations link to the problem formulation<br /> 3) Map the current planning and control system.<br /> 4) Develop a “to be” state<br /> 5) Exemplify with a case description<br /> <br /> Findings: Trioplast Landskrona should develop a hierarchical planning and control system containing four separated levels of planning. This system should spring from the company’s business plan and then link operations with the business plan. The four levels of planning are called sales and operations planning, master scheduling, requirements planning and shop floor control.<br /> To develop their current system into the new, Trioplast Landskrona’s planning meeting needs to develop into a sales and operations planning process with an executive meeting. The planning hierarchy shall from now include a master scheduling that is handled by the company’s head of planning, also a new master planning meeting shall be introduced. Lastly, the company’s shop floor Control planners should divide their work in terms of product families instead of production departments. https://lup.lub.lu.se/student-papers/record/4175243/file/4175250.pdf application/pdf 3523461 no 2013 swe Planerings- och styrsystem Hierarkisk planering Sälj- och verksamhetsplanering Huvudplanering Behovsplanering Materialplanering Kapacitetsplanering Detaljplanering Produktionsplanering Planning and control system Hierarchical planning Sales and operations planning Master scheduling Master planning Requirement planning Material planning Capacity planning Shop floor Control Production activity control Production planning Technology and Engineering https://lup.lub.lu.se/student-papers/record/4175243/file/4175252.pdf application/pdf no 4175243 2013-11-26T13:07:35+01:00 2013-11-26T13:25:37+01:00 2013-11-26T13:25:37+01:00

För att skydda mjölk från ljus, kan dess förpackning innehålla aluminiumfolie. Det laminerade aluminiumfoliet ger en utmärkt ljusbarriär, men är dyrt och är inte ett förnybart material. För att kunna ta bort eller ersätta aluminiumfoliet och samtidigt inte förlora för mycket av förpackningens ljusbarriär är det viktigt att få kunskap om ljusbarriäregenskaper för andra material än aluminiumfolie.<br /> I det här examensarbetet har fokus legat kring ljusbarriärer för material, som kan användas för okylda mjölkförpackningar. För okyld mjölk får inte ljustransmissionen (andel ljus, som penetrerar ett föremål) överskrida 0.1%.<br /> Två olika slags spektrofotometrar fanns tillgängliga för ljusbarriärmätningarna. En av maskinerna var en dubbelstråle spektrofotometer, som användes för att mäta plana prov. Den andra var en kupol spektrofotometer, som användes för att mäta tredimensionella strukturer.<br /> Undersökningarna av papprena för 1 liters förpackningarna visade att de skyddade mot ljus med våglängder som gav upphov till bismaksreaktioner med Riboflavin (220-275,410-475 nm). Men transmissionen i våglängdsintervallet 650-700 nm var över 0.1%. Dessa våglängder ger upphov till bismaksreaktioner med porfyriner och chloriner.<br /> Plastkorkarna på förpackningarna utgör en bråkdel av förpackningens totala area. Men ljusbarriären hos hela förpackningen kan försvagas på grund av plastkorken, vilket är anledningen till varför den har undersökts.<br /> Ljusbarriären hos papper, plastkorkar och förpackningar från marknaden undersöktes.<br /> Papper som användes för en liters mjölkförpackningar hade mindre än 0.1 % transmission för våglängder upp till 500 nm.<br /> Fysikaliska egenskaper, som tjocklek påverkar ljusbarriären. De olika lagren i kartongen bidrar olika mycket till ljusbarriären.<br /> Pigmentet i plastkorkar påverkar ljusbarriären. Den bruna korken från Tetra Pak och den blå kommersiella korken hade tillräckligt bra barriär mot bismaksreaktioner med Riboflavin, kloriner och porfyriner.<br /> Tryckfärgen förbättrar ljusbarriären på papper. Detta kan användas som ett alternativt sätt att förbättra ljusbarriären i papper. The thesis started 15th January in 2013 at Tetra Pak Packaging Solutions AB in Lund.<br /> Milk is a product that is particularly sensitive to light. In order to protect milk from light, its package can have aluminium foil. The laminated aluminium foil provides an excellent light barrier but is expensive and not a renewable material. To be able to remove the aluminium foil and not lose too much of the package´s light barrier it is important to obtain knowledge in light barrier properties of other packaging materials than aluminium foil. Aluminium also provides a barrier against other components that may harm the milk, for example moist and oxygen, however this report will only focus on light barrier.<br /> The light barrier for ambient stored milk has been the focus during the thesis. Most of the light barrier is located in the paperboard for milk packages. For milk stored at ambient temperature, the light transmission (light that penetrates a sample) should not exceed 0.1%.<br /> Two different kind spectrophotometers were available for the light barrier measurements. One of the machines was U-3010 spectrophotometer which is a dual beam spectrophotometer that were used to measure flat samples. The other spectrophotometer was a dome spectrophotometer that was designed to measure on three dimensional structures.<br /> The investigation of paperboards for 1 litre packages showed that they had protection against light of wavelengths that induced off flavour reactions with Riboflavin (220-375, 410-475 nm). But the transmission for light within the range 650-700 nm was above 0.1%. Those wavelengths induce off flavour reactions with porphyrins and chlorins.<br /> The plastic caps on packages are a rather small part of the total package in term of area. But the light barrier of the total package could be lacking due to the plastic caps which is why they have been investigated. <br /> The light barrier properties of paperboard, plastic caps and packages available in the market were investigated.<br /> The paperboards used for 1 litre milk packages have less than 0.1% light transmission for wavelengths up to 500 nm. This means that they give enough protection against light that induce off-flavour reactions with riboflavin, but may still be subjected to light induced off-flavour reactions with porphyrins and chlorins.<br /> Physical properties such as grammage and thickness affect the light barrier in paperboard, because the thicker a sample, the lower the light transmission according to Lambert-Beer’s law. Some layers in the paperboard contribute more to the light barrier than others, due to different chemical composition.<br /> The pigment in the plastic caps affects the light barrier. The brown plastic cap supplied by Tetra Pak and one blue cap available in the market had sufficient light barrier against off-flavour reactions with Riboflavin and also had low transmittance for the wavelengths where chlorins and porphyrins cause off flavour reactions.<br /> The printing on paperboard improved the light barrier and transforming the paperboard into a package by creasing and then folding didn’t result in a weakened the light barrier. This means that the light barrier of a paperboard still remains or has improved after being transformed into a package. https://lup.lub.lu.se/student-papers/record/4175246/file/4180298.pdf application/pdf 2485320 no 2013 eng Technology and Engineering https://lup.lub.lu.se/student-papers/record/4175246/file/4175261.pdf application/pdf no 4175246 2013-11-26T13:12:14+01:00 2014-01-07T13:48:58+01:00 2014-01-07T13:48:58+01:00

studentPublicationsM2 Sara Eklund author 4175562 Johan Lundström author Professor Kenneth M Persson supervisor Division of Water Resources Engineering v1000225 department Problem Definition: For several hundreds of years, mining in Bolivia has been an important part of the economy. The mining activity has a negative effect on both the environment and the health of the people. Previous studies conducted in the Lake Poopó area show elevated concentrations of heavy metals and ions harmful to people and nature. Also, previous studies indicate that the contamination from mining activities is significant for the water quality. Four larger rivers flow through the studied area; the Poopó, Pazña, Urmiri and Antequera Rivers. A large quantity of mines but also farms and villages are situated in the basins of some of these rivers. This, together with the geological composition of the bedrock, highly pollutes the water that in turn is used by the people in these villages. <br /> <br /> Objectives: The main objective of this thesis is to gather knowledge of the present environmental condition of the Poopó, Pazña, Urmiri, and Antequera River basins, with focus on heavy metal concentrations in superficial waters. Also, to increase the understanding of how the heavy metal concentrations have changed during the years of studies conducted in the area.<br /> <br /> The questions to answer include:<br /> • What are the concentrations of the heavy metals cadmium, copper, zinc, manganese, iron, arsenic, and lead in the Poopó, Pazña, Urmiri, and Antequera River basins?<br /> • Do the heavy metal concentrations change over time?<br /> • How much of the heavy metal concentrations are caused by anthropogenic and natural contamination, respectively?<br /> • How is the water quality compared to the health-based WHO guidelines for drinking-water? <br /> <br /> Our hope with this study is that the gained knowledge will help in the effort of developing long-term sustainable plans for remediation and water resource management that will benefit the people living in the Poopó, Pazña, Urmiri, and Antequera River basins.<br /> <br /> Method: This thesis summarizes information from previous studies as well as analyzes data values from a field trip conducted in June 2013. During the field trip samples of surface water were collected and analyzed. In the field, the parameters pH, Eh, temperature, conductivity, TDS, and alkalinity were measured and the water samples were divided into two bottles for further analysis in laboratory. At the San Andrés University in La Paz the water was analyzed regarding concentrations of the ions nitrate, sulfate, chloride, sodium, potassium, calcium, and magnesium and the concentrations of the heavy metals lead, manganese, arsenic, iron, copper, zinc, and cadmium. Data from previous studies were collected, organized and compared in order to see if and how the heavy metal concentrations change over time.<br /> <br /> Results and Conclusion: <br /> Current Situation<br /> The samples collected during the field trip in June 2013 make up the current situation analysis. The concentrations for nitrate, cadmium and arsenic all exceed the WHO health-based guideline values for drinking-water in the Antequera River. A thermal spring that leaks into the Urmiri River, together with the natural bedrock weathering, affects the water and elevates temperature, chloride, sodium, and cadmium concentrations. Since there is no larger mine activity contaminating the water in the Urmiri River, a comparison between the Antequera and Urmiri River gives an approximate indication of how much the mines affect the water quality. This comparison indicates that the Antequera River is highly polluted due to contamination from mines, especially regarding cadmium. The results also indicate that the characteristics of Pazña River are a mixture of those of Urmiri and Antequera River. Furthermore, it seems as though the mine-influenced sampling site MAD1, a tributary of the Poopó River, impairs the water quality of the main river to a great extent.<br /> <br /> Historical Situation <br /> The data from previous studies have been divided into dry and rainy period, respectively, where an analysis of heavy metal contamination has been made only of the dry season data values. This study, similar to the study of the current situation, indicates that the area north east of the Lake Poopó is polluted and that Antequera River is the river most affected by mining activity. In that particular river, the concentrations for cadmium, iron, zinc and manganese exceed the WHO guideline values at almost every sampling site and date. Especially cadmium vastly exceeds the WHO limit. Meanwhile, the values for the Urmiri River rarely exceed the WHO guideline values. The heavy metal values for Pazña River are also often above the WHO guideline values, probably due to the inflow from Antequera River. The sampling site MAD1 greatly affects the Poopó River and elevates the heavy metal concentrations. A clear trend for all four rivers is the constantly elevated concentrations of cadmium that is neither increasing nor decreasing up to June 2013. For sampling sites PAZR1 and POR3, where the data sampling starts as early as 2001, the arsenic and lead concentrations are high above the WHO guideline values until June 2007. After this, the levels seem to have stabilized close to or below the WHO guideline values. Sampling site MAD1 does not, however, follow this pattern but instead has extremely elevated arsenic and lead concentration up to June 2013. The sampling site AVR1 has only been studied since 2007. There, the levels of arsenic and lead have historically had one peak each but otherwise stay around the WHO guideline values for drinking-water. https://lup.lub.lu.se/student-papers/record/4175551/file/4175558.pdf application/pdf 4083897 no 2013 eng Mining Water quality Heavy metals Ions Superficial waters Antequera Pazña Urmiri Poopó Technology and Engineering 1101-9824 13/5018 This study has been carried out within the framework of the Minor Field Studies (MFS) Scholarship Programme, which is funded by the Swedish International Development Cooperation Agency, SIDA. The MFS Scholarship Programme offers Swedish university students an opportunity to carry out two months field work in a developing country resulting in a graduation thesis work, a Master’s dissertation or a similar in-depth study. These studies are primarily conducted within subject areas that are important from an international development perspective and in a country supported by Swedish international development assistance. The main purpose of the MFS Programme is to enhance Swedish university students’ knowledge and understanding of developing countries and their problems. An MFS should provide the student with initial experience of conditions in such a country. A further purpose is to widen the human resource base for recruitment into international co-operation.

The general idea of NMPC is to solve an optimization problem, to nd the next control action, and this optimization problem is based on a model of the system. The models used in the controller implementation are Modelica-based, and the system is described by algebraic dierential equations (DAEs).<br /> <br /> The controller was implemented in the Python interface of JModelica.org (Modelica-based modeling tool, supporting the Modelica extension Optimica for optimization), together with an extended Kalman lter (EKF) for state estimation. The control algorithm was only evaluated for a setup where the controller model is very similar to the model representing the real process; both models are simplied representations of the real process. https://lup.lub.lu.se/student-papers/record/4175598/file/4180010.pdf application/pdf 2555110 no 2013 eng Optimization Nonlinear Model Predictive Control Extended Kalman lter Modelica Optimica JModelica.org Technology and Engineering 0280-5316 ISRN LUTFD2/TFRT--5926--SE https://lup.lub.lu.se/student-papers/record/4175598/file/4180012.pdf application/pdf no 4175598 2013-11-27T13:41:42+01:00 2013-12-02T09:45:02+01:00 2013-12-02T09:45:02+01:00

I andra hand ska förbättrande åtgärder utarbetas och provas. Arbetet ska avse vara en del i underlaget inför utvecklingen av systemet.<br /> <br /> Slutsatser: Miljöbyggnad är i sin nuvarande utformning ett fungerande miljöcertifieringssystem. Trots det finns det utrymme för justeringar för att förbättra och utveckla systemet. Den aggregeringsmetod som används för betygssättning i gällande version har både för- och nackdelar. Det finns indikatorer vars betyg är svåra att påverka då de beror på byggnadens belägenhet. På grund av aggregeringsmetoden blir det nästan avgörande i de fall där högre byggnadsbetyg eftersträvas. Detta, tillsammans med de indikatorer som har svåruppnåeliga kriteriegränser, medför att aggregeringsmetoden kan upplevas som en hård betygssättningsmetod. I kontrast till detta är en fördel att inga indikatorer kan förbises, vilket kan göras med andra certifieringssystem.<br /> Det finns inga enkla lösningar för att hantera det genomslag enstaka indikatorer kan få på slutbetyget om man inte vill frångå principen att en GULD-klassad byggnad inte får ha BRONS-klassade indikatorer. Däremot kan man med små justeringar underlätta då indikatorer hamnar i konflikt med varandra. Bland annat kan ett oviktat poängsystem införas vilket möjliggör att gränser för byggnadsbetyg kan sättas manuellt. Att slå ihop vissa indikatorer under samma aspekt medför vissa effekter som kan ändra förutsättningarna i aggregeringen. Likaså kan man få motsvarande effekt genom att omgruppera områdena. Samtidigt fyller aspektnivån endast en begränsad funktion och kan övervägas att tas bort. Enskilda indikatorer har förbättringspotential då de antingen upplevs som för svåra att uppnå högre betyg på alternativt saknar tydlig motivering.<br /> Betygsoptimering, det vill säga att endast de indikatorbetyg som är nödvändiga för byggnadsbetyget höjs, är vanligt oavsett miljöcertifieringssystem, så även för de fastighetsägare som väljer att använda Miljöbyggnad. Dock bör det inte betraktas som något som måste motarbetas så länge kriteriegränserna är rimliga och ligger på en jämn nivå. Det förefaller naturligt att olika beställare/byggherrar väljer att fokusera mer på vissa aspekter än andra. Miljöbyggnad säkerställer dock att en viss grundnivå alltid är uppnådd.<br /> Det finns intresse och utrymme för att komplettera Miljöbyggnad med ytterligare områden för att förbättra bedömda byggnaders miljöprestanda. Dock måste en utvidgning av systemet ske med eftertanke för att systemet inte ska bli för omfattande. Det skulle hämma användandet av det. Det mest eftertraktade området handlar om resurshantering. Här föreslås en uppdelning i två aspekter med två indikatorer vardera. Den ena rör avfallshantering i drift respektive produktionsskedet, den andra gäller vattenresurser som delas upp i dagvattenhantering och vattenanvändning. The Issue/problem: What measures can be taken to address the development needs Miljöbyggnad are facing regarding its rating system and detailed design of indicators?<br /> <br /> The Purpose: The purpose is primarily to evaluate the rating system in Miljöbyggnad. Secondly, improvement measures will be developed and tested. The work will relate to being part of the basis for the development of the system.<br /> <br /> The Conclusions: Miljöbyggnad is in its current form a well functioning environmental assessment method. Still, there is room for adjustments to further improve the system. The aggregation method used for grading has both advantages and disadvantages. Some of the included indicators are location-dependent, thus very difficult to affect by the contractor. This, along with other indicators having hard to meet criteria’s, makes the aggregation method a somewhat harsh grading-method. In contrast to this, the method does not allow for any aspect to be overlooked, which more easily can be done in the other systems.<br /> There are no easy solutions to manage the impact individual indicators can have on the final grade if you do not want to deviate from the principle that a GOLD-rated building may not have BRONZE-rated indicators. However, with small adjustments it is possible to ease up when indicators conflict with each other. For example, a scoring system would allow the rating limits to be set manually. Merging some indicators within the same aspect brings some effects that can alter the conditions of aggregation. One can also get a similar effect by regrouping sections. The aspect-level in Miljöbyggnad has limited function concerning the grading of buildings and can consider to be removed. Regarding some individual indicators there is room for improvement where they either is perceived as too difficult or lacks clear justification.<br /> Choosing the easiest way to a certain grade is a common phenomenon in all environmental assessment methods, this also applies to Miljöbyggnad. It seems natural that different purchasers/developers choose to focus more on certain aspects than others. As it exists, it ́s important to establish an even level between indicators and reasonable criteria-levels for each and every one of them.<br /> Regarding the system boundary of Miljöbyggnad, there has been a discussion about widening it, thus allowing for a broader environmental assessment. However, an extension of the system should be implemented carefully given the risk of inhibiting its usage as a consequence of becoming to extensive. The most requested section to be added is resource management. Such a section is possible to split in two aspects with two indicators each. The first aspect, Waste, deals with waste management in operation and production stage. The other, Water resources, are split into storm water management and water use. https://lup.lub.lu.se/student-papers/record/4186699/file/4186713 application/pdf 2864223 no 2013 swe Miljöklassning Miljöcertifiering Aggregering Environmental classification Environmental assessment method Aggregating Miljöbyggnad LEED BREEAM Miljöbyggprogram SYD Technology and Engineering https://lup.lub.lu.se/student-papers/record/4186699/file/4186715 application/pdf En populärvetenskaplig artikel baserad på examensarbetet Utveckling av Miljöbyggnad - En analys av åtgärdsalternativ. no The Authors Jonny Ericson and Kristian Larsen contributed equally to the report. 4186699 2013-12-03T16:02:39+01:00 2015-07-01T15:07:14+02:00 2014-10-28T10:25:07+01:00

New cultivable areas must be explored and developed. Is the construction of greenhouses on existing rooftops in urban environments possible, and how can this benefit a city like Malmö? Purpose: The purpose of this project is to display how a greenhouse may be constructed on an existing rooftop in Malmö and the conditions that must be considered. By implementing energy simulations, we observe what impact different materials can have on the greenhouse’s energy savings. We also want to demonstrate the beneficial effects that the building can generate for the local area and the city of Malmö. Method: The two main components of this project consist of investigating how the greenhouse could be constructed on the rooftop and how it would be as energy efficient as possible based on the wishes of the property owner. To see which conditions exist for the new construction, we have performed literature studies followed by calculations. Energy simulations were carried out in a simulation program called Derob LTH, where energy calculations are based on the indoor temperature desired for the greenhouse. Results: By using double-glazing in connection with shading fabrics in the greenhouse up to 41 percent more energy savings can be achieved in comparison to a construction with single-glazing with shading fabrics were used. For the greenhouse to be built, a steel construction with a new floor structure needs to be constructed on the outside of the existing building. The outcome of the greenhouse being built will result in that Malmö&#39;s image as a green city is being promoted. Key words: Rooftop greenhouse, Energy upgrade, New construction, Construction, Greenhouse technology. https://lup.lub.lu.se/student-papers/record/4194017/file/8961708.pdf application/pdf 6434236 no 2013 swe växthus på tak energieffektivisering nybyggnad konstruktion växthusteknik Technology and Engineering 4194017 2013-12-08T00:00:00+01:00 2018-10-18T10:28:12+02:00 2013-12-10T00:00:00+01:00

New ways of<br /> living and cooking generates a<br /> need of rethinking the kitchen<br /> and the appliances to better<br /> fit the demands and desires of<br /> modern living.<br /> This concept helps the user include<br /> the dishes as an easier<br /> part of cooking, and an encouragement to rediscover the<br /> health and pleasure of providing<br /> one’s own meals.<br /> The project is focused on kitchens<br /> for smaller apartments -<br /> where there is limited space in<br /> the kitchen. First impression of<br /> this dishwasher is easily recognized. It is under the casing<br /> where most of the improvements<br /> have been design. The<br /> concept was developed in collaboration with Hans Bolinsson,<br /> laboratory engineer at the University of Lund, food technology. The cleaning process with<br /> ultra-sonic was tested, and<br /> revealed several advantages<br /> compared to today’s table top<br /> dishwashers. The technology<br /> uses high frequency sound<br /> waves (from 20–400 kHz) to<br /> agitate the water that is filled<br /> inside the machine. Cavitation<br /> bubbles induced by the agitation<br /> remove the dirt from the<br /> dishes. The process lasted for<br /> 5 minutes and gave a complete<br /> and clean result. The amount<br /> of energy used was calculated<br /> to be less per each washing cycle<br /> than compared to a regular<br /> washing machine.<br /> Cleaning dishes is a burden<br /> that has to be dealt with before<br /> getting on with other agendas.<br /> People may consider other alternatives<br /> to cooking their own<br /> food in order to get away from<br /> the cleaning process. Even before<br /> starting to prepare a meal,<br /> one could think “is this even<br /> worth the effort, I will have to<br /> clean up after cooking?”<br /> This dishwasher can easily be<br /> placed in a smaller kitchen and<br /> provide the user with a convenient and efficient way of<br /> dealing with dishes. https://lup.lub.lu.se/student-papers/record/4194331/file/4194332.pdf application/pdf 9364389 yes 2013 eng Technology and Engineering Agriculture and Food Sciences ISRN ISRN: LUT-DVIDE/ EX--12/50176—SE 4194331 2013-12-10T15:53:06+01:00 2013-12-10T16:13:01+01:00 2013-12-10T16:13:01+01:00

As more advanced packages are developed the correct mechanical properties for the adhesive strength is needed to make packages cost efficient and reliable.<br /> <br /> The problem today is that no good evaluation technics have been developed for determining the mechanical properties of adhesives. Different test methods for determining adhesion was studied. Peel tests were found most suited and were used when performing experimental tests on the package material. The purpose of the experimental tests were to evaluate the mechanical adhesion properties. FE-simulations were done to replicate the experimental peel tests with the aim of determining the correct adhesion properties needed in simulations. ABAQUS/Standard was used for the FE-simulations. <br /> <br /> It was found that it is difficult to evaluate the properties needed by only using peel tests. It was also found that it is possible to match the peel force from experimental tests with the peel force from FE-simulations. It is hard to say if the correct properties were used since many combinations yields the same peel force. Not only the adhesion parameters affects the result. If the goal is to fine tune the adhesion parameters in simulations, then all other parameters should be validated first. As an example, it is critical that the correct material models are used.<br /> <br /> The conclusion is that there is still a great research need before a method for evaluating adhesion strength is developed. With new experimental test methods and correct material models, good estimations of the adhesion properties could be made. This study brings up topics that further studies on adhesion would need to address. https://lup.lub.lu.se/student-papers/record/4195162/file/4195163.pdf application/pdf 10756508 no 2013 eng FEM finite element abaqus abaqus/standard simulate adheison cohesion tetrapak tetra pak peel test peeltest packaging material cohesive element cohesive elements adhesion test LTH byggnadsmekanik byggmek Technology and Engineering http://www.byggmek.lth.se/ 0281-6679 TVSM-5188 4195162 2013-12-12T22:37:52+01:00 2014-10-21T13:47:21+02:00 2014-10-20T14:53:17+02:00

This is done in order to suggest some tentative ideas on how to further develop<br /> the emerging ICT cluster in Malmö/Lund.<br /> Four sub purposes have been applied in order to achieve the main purpose:<br /> To understand why Silicon Wadi in Israel has become such a successful and<br /> sustainable ICT cluster<br /> To benchmark the cluster in Silicon Wadi and the one in Malmö Lund: Which are<br /> (or seems to be) the key similarities and differences between Silicon Wadi in Israel<br /> and the Malmö/Lund region?<br /> To use the benchmarking to propose ideas on how to address some of the<br /> challenges that faces Malmo/Lund as a regional innovation system<br /> To develop a theoretical framework for exploring and comparing regional<br /> innovation systems.<br /> <br /> Method<br /> The study has been conducted mainly through two case studies where the ICT clusters in<br /> Silicon Wadi and Malmö/Lund have been studied. The method used to carry out these<br /> studies has primarily been literature studies, collecting mainly qualitative data.<br /> Theoretical Framework<br /> The empirical data has been analyzed with a model developed in this thesis called The<br /> Innovation Ecosystem Model. This model is a composition of theories within the theoretical<br /> sphere around clusters and innovation systems. The model is an attempt to describe and<br /> understand a regional innovation system, or a cluster, in three different dimensions<br /> namely Context, Actors and Activities. The context has been analyzed using Michael E.<br /> Porter’s diamond model, the actors with the triple helix model and the activities with<br /> Charles Edquist’s activity based approach to innovation systems.<br /> Conclusions<br /> There are many success factors behind the Israeli ICT cluster in Silicon Wadi, but some<br /> of the main factors determining the success of the cluster have been focused government<br /> initiatives, well developed capital markets, well developed commercialization<br /> infrastructure, a focus on high quality R&amp;D and education, the characteristics the military<br /> service imposes on the population, a culture well suited for entrepreneurial endeavor and<br /> a high degree of international collaboration.<br /> In order to create a bright future of the cluster in Malmö/Lund actions needs to be taken<br /> on three different levels, societal challenges such as integration problems and high<br /> unemployment rates must be addressed, systemic challenges in the innovation system has<br /> to be addressed and finally a creative environment has to be built in accordance with<br /> Richard Florida’s theories on creative capital.

The data is then simulated for general materials with suitable parameters and a general graph is generated from the simulations. The graphs are applied to the real life materials and a validation of the model is to be done.<br /> Conclusion<br /> This report shows that a maritime set up for stock refill between local and central warehouses in the affected routes are generally very interesting for heavy weight materials with high demands. There are several interesting materials even within TSAB (Tetra Pak Technical Service AB) but the spare parts business is not the most suitable area for sea transportation due to the low volumes and erratic<br /> VI<br /> materials. Despite this there are still enough incitements even within these materials to introduce a process to handle the few obviously interesting materials.<br /> Regarding the environmental impact (measured as the emission of carbon dioxide) it´s clear that sea transportation is a more sustainable alternative. But as long as the company policy is unclear regarding the value of reducing the impact or no targets are set to reduce the total impact it´s not feasible to include it as a cost in a separate decision as the one discussed in this report. https://lup.lub.lu.se/student-papers/record/4195351/file/4195353.pdf application/pdf 1880288 no 2013 eng Supply Chain Efficiency Transportation mode Environmental cost Technology and Engineering 13/5469 4195351 2013-12-13T13:33:22+01:00 2013-12-13T13:40:35+01:00 2013-12-13T13:40:35+01:00

However, new technology also brings new risks. Since most widely accepted standards and regulations are not directly aimed for subsea systems, new methods have to be developed. By developing a LOPA-model, which can be used specifically for subsea context, this thesis intends to be a part of filling that gap. The models main objective is to evaluate subsea production system risk and to determine the appropriate safety Integrity level (SIL) for all present independent protection layers. The method is semi-quantitative in nature, which means that the model output is based on a combination of generic statistical data, expert judgement and logical reasoning. According to the model validation, the result seems to be credible due to what is economically and technically feasible. For example, when a single satellite well subsea system was evaluated it ended up with SIL3 requirements for the “isolation of well function” and lower SIL requirements for other less critical safety functions. https://lup.lub.lu.se/student-papers/record/4195391/file/4195399.pdf application/pdf 2916708 no 2013 eng Failure frequency failure mechanisms hydrocarbons leakage LOPA LOPA-credit offshore oil protection layers SIL SIS subsea subsea system felfrekvens felmekanismer hydrokarboner läckage olja skyddsbarriärer Technology and Engineering 1402-3504 5428 4195391 2013-12-13T14:02:16+01:00 2014-03-10T10:40:46+01:00 2013-12-13T14:08:20+01:00

When electronic devices are used in biomedicine, especially when needed for chronic implantation, their ongoing downscaling is largely motivated by two aspects: biocompatibility and specificity. It has been shown that downscaling is a way to significantly decrease the damage done by such devices.<br /> In the research and development of new, complex devices, these need be continuously evaluated in various ways. In vivo experiments are one necessary part, and in vitro cell cultures are far from a complete substitute to an entire animal, but they constitute a very useful model nonetheless. There are three main drawbacks to in vivo testing: the cost, the complexity of the living organism – which can be an obstacle in routine tests – and animal suffering – the main reason why animal testing should only be used if there is no other sufficient option. Consequently, cell cultures can be much more appropriate in some instances.<br /> The aim of this project was to set up a quick-stop in vitro test station at which different electrode designs can be tested against one another. An existing setup originally assembled for patch clamp experiments was used with cell cultures chosen for other experiments primarily. PC12 cells and later mouse cortical neural stem cells were stimulated with KCl to produce action potentials. For PC12 cells no action potentials were registered, and for the cortical stem cells the consistency sought was not achieved. It is possible that this setup, using cortical stem cells, can achieve the intended practical use, but this project cannot assess this finally. https://lup.lub.lu.se/student-papers/record/4195510/file/4195512.pdf application/pdf 1297138 no 2013 eng Technology and Engineering https://lup.lub.lu.se/student-papers/record/4195510/file/4195533.pdf application/pdf no 2013-10 4195510 2013-12-13T15:36:37+01:00 2014-10-08T14:47:32+02:00 2013-12-13T15:54:32+01:00

The practical work focuses on the important steps in channel design, droplet generation and the possibilities to manipulate polystyrene particles with a diameter 10 _m inside channels with widths of a few hundreds of _m. The particles are manipulated inside water droplets dispersed in an continuous oil phase and the results include an examination of the droplet flow fields in interaction with the primary radiation force.

The complexity of reinforced concrete makes modeling and simulation of large structures time and computer power consuming. Consequently, The Swedish Defense Research Agency, FOI, has an interest in finding a fast and numerically efficient model to study this response to a reasonable cost.<br /> <br /> A FOI report investigates the possibility to use a simplified numerical model of reinforced concrete slabs to simulate the response from blast loads and quasi static loads. The model is based on three-dimensional solid elements and a combined concrete/steel material model. The results are compared to an experimental study.<br /> <br /> This thesis introduces a further simplified model of the concrete slabs based on shell element formulation. A combined concrete/steel material model for shell and beam type elements is used. Layered design is used where the reinforcement is smeared over a layer corresponding to the allocation of the longitudinal bars. The introduced model is used to simulate a part of a multi-story building subjected to blast load. The results are compared to existing results from experiments performed on structures in 1:4 scale.<br /> <br /> Simulations of the slabs using a shell element formulated model shows that the shell model can predict the response of a blast load with similar accuracy as the solid element formulated model. For two different charge weights, the maximum deflection is however 1.6 and 2.2 times bigger than the results from experiments. The shell element formulated slab predicts a fair response from quasi static loads, but not with the same accuracy as the solid element slab.<br /> <br /> Simulations of the multi-story building shows a façade mean deflection 3.0 times bigger than the experimental results. Additionally, the deflection remains permanent as opposed to the experiment where the permanent deformation is close to zero.<br /> <br /> The introduced model is deemed to be able to constitute a base for further studies of simulations with shell element formulated concrete structures. A first step would be to introduce a more correct blast load for a better evaluation of the response. https://lup.lub.lu.se/student-papers/record/4220125/file/4699302.pdf application/pdf 1984583 no 2013 eng Load blast reinforced concrete structural response finite element analysis LS-DYNA LOAD BLAST ENHANCED shell element Technology and Engineering http://www.byggmek.lth.se/ 0281-6679 TVSM-5193 4220125 2013-12-19T11:06:28+01:00 2014-10-24T13:54:27+02:00 2014-10-24T13:54:27+02:00

With today logistics and production trends, where terms such as Lean Production, Six Sigma, 5S, and World Class Manufacturing are used every day, production companies are introducing streamline production facilities and supply chain where goods and raw material are delivered just in time, where buffer zones are reduced, and where suppliers are reduced to a single source. These are trends that strengthen companies’ competitiveness, but it also makes companies more vulnerable to risk events. <br /> Volvo Powertrain in Köping is implementing World Class Manufacturing in Köping, and they are aware that there are risks that can harm the production and delay deliveries to their customers. They were looking for a tool that could visualize the consequences of such event to enable quick decision making.<br /> From known historical events and from Volvo Powertrains request, a two folded purpose was developed. The first purpose was to perform a risk assessment on the production facilities at Volvo Powertrain in Köping and to find and analyze risks within the factory that has a high impact on the production. The second purpose of this master thesis was to develop a simulation model for a production industry that visualizing the consequences of a disruption and enables quick decision making. To make this possible, a single case study together with the empirical quantitative-based simulation methods was used whilst the theoretical foundation was based on the AS/NZS 4360: 2004 standard. <br /> A simulation model was developed using the probability safety assessment program RiskSpectrum. This required an accurate collection of information to reflect reality as good as possible. The information collected contained historical risk events, different machine flows, different article numbers, fire cells etcetera, resulting in a simulation model containing almost 400 machines, 200 machine cells, 170 article numbers, and 600 different flows. The result were transferred to a Excel-file making it possible for the user to search on a machine or article number, and to see what machine are connected to which article numbers, and which machine that are critical and cannot be replaced by a different flow in the production line. The simulation also showed that many articles produced are critical connected to at least one or more machines that cannot be replaced today by another machine or by a 3rd party.<br /> This master thesis does not intend to speak against new logistic and production trends, but rather to show how important it is to develop a strategy on how to handle risks when a risk event occurs. By having a well-developed action plan, a costly risk event can turn into a business opportunity. https://lup.lub.lu.se/student-papers/record/4221896/file/4438614.pdf application/pdf 1604659 no 2014 eng Risk Management Supply Chain Risk Management Fault Tree Analysis Preliminary Hazard Analysis Lean Production Risk Matrix World Class Manufacturing Fire Safety Volvo Powertrain Business and Economics Technology and Engineering 14/5119 4221896 2013-12-20T15:27:55+01:00 2015-08-19T14:06:16+02:00 2014-05-23T09:15:28+02:00

studentPublicationsM2 Mohammad Taha author Programmes in Helesingborg v1000317 department A train accident at high speeds can result in serious consequences, and in worst case the loss of human life. Hence, there are stringent requirements related to traffic safety on the railway system. These requirements are valid for both the infrastructure and the rolling stock.<br /> The overall purpose of this work is to increase the understanding of the management of safety critical faults within the railway system, and thereby support an effective management of safety critical faults with maintained or increased safety. The work explores how the evaluation and follow-up of safety critical faults are performed and what facts that decisions about actions related to safety critical faults are based on. The goal of the work is to identify overarching suggestions for actions to improve the management of safety critical infrastructure faults within the Swedish railway, by an analysis of data obtained from measurement wagons.<br /> The overarching methodology in this work is a case study of the Iron ore line. Data has been collected through the analysis tool Optram and the asset register BIS, as well as document studies, observations and interviews with involved actors. The analysis is based on the &quot;Seven improvement tools” and has mainly been performed with the aid of Pivot tables in Microsoft Excel.<br /> The result includes identified causes to track geometry faults and related suggestions for actions. The result also pinpoints weaknesses in the machine-based evaluation of track geometry faults and the management of measurement results. One problem in the management of measurement results is an insufficient integration between different sources and formats of data. For example, the follow-up of track geometry faults, which can be judged either by machine or manually, is based on a manual administration of lists with no clear end-time for correction of fault. A related example is that track geometry faults that are registered in Optram are not found in 0felia. Another example of insufficient integration is dissimilarities between different measurement conditions, for example between heavy iron ore trains, lighter measurement wagons, and un-weighted manual measurements. These differences lead to unwanted events such as undetected faults, insufficient fault localization, and “no fault found”. To detect track geometry faults that are present during iron ore traffic, the measurement wagons of today have to be further developed, or the iron ore trains need to be instrumented. The localization of faults is hampered by the insufficient positioning of measurement results; however, today there is available GPS-technology that should be possible to use in order to greatly enhance the positioning, both within and between measurements. The latter should also contribute to an improved analysis of failure development and a more condition-based maintenance practice. https://lup.lub.lu.se/student-papers/record/4225973/file/8961709.pdf application/pdf 2084966 no 2014 swe Technology and Engineering 4225973 2013-12-20T00:00:00+01:00 2018-10-18T10:28:14+02:00 2014-01-03T00:00:00+01:00

The amount of connections in the societal system makes it impossible, without a tool, to take all consequential effects of a perturbation in consideration. The concept of urban flows is previously developed to help resolve this issue and it is further developed in this thesis. The goal of the thesis was to create a calculation methodology that aggregate dependencies and influence from actors to urban flows on a municipal level. The developed calculation methodology is based on assumptions and the accuracy of the results is limited by these assumptions. A MATLAB based computer tool was developed to aggregate dependencies and influence according to the calculation methodology and visualise the results.

The study shows that no common understanding of the meaning of the terms adequate and equal has been reached since the Civil Protection Act (LSO) was taken into use. This has caused a non-homogenous perspective on the meaning of the terms and the methods to achieve such protection, which in turn could cause differences in the protection against accidents throughout the country. Based on the study it is recommended that a common meaning of the terms be established, and more guidelines and elaboration in regards to how to achieve an adequate and equal protection be given. Several people whose work is affected by the Civil Protection Act share this opinion. However, it is important that these operational definitions and guidelines do not become too detailed, or the purpose of the law change will be lost. https://lup.lub.lu.se/student-papers/record/4229530/file/4229533.pdf application/pdf 1318025 no 2013 swe tillfredsställande likvärdigt lag om skydd mot olyckor begrepp metoder definitioner definitions methods concept the Civil Protection Act Adequate equal Technology and Engineering 1402-3504 5436 4229530 2014-01-08T14:11:31+01:00 2014-03-10T10:40:46+01:00 2014-01-08T14:16:18+01:00

Dock kvarstår flera frågor relativt outforskade och obesvarade. En sådan fråga är hur användande av GIS ser ut inom offentliga organisationer (så som Polisen, Räddningstjänsten och Ambulansverksamheten). I vår studie söker vi svar på vilken typ av GIS som bäst lämpas för dessa organisationer och vilken användningsmetod som bör tillämpas. Genom att använda ”GIS Effectivness in Crisis Management”-modellen, utökad med ett systemimplementeringsperspektiv, sammanställer vi ett antal faktorer som vi använder som stommen till vår kvalitativa studie. Vi finner att två olika användningsmetoder brukas primärt inom detta område. Den första är anpassning, vilket innebär att systemet skräddarsys för den enhet som ska bruka det. Den andra är standardisering, vilket innebär att samma system implementeras i hela organisationen. Slutsatsen vi drar är att anpassning är en tveksam lösning, trots hög uppskattning från våra respondenter, samt att standardisering är det mer optimala sättet att använda GIS inom detta område. https://lup.lub.lu.se/student-papers/record/4231015/file/4231023.pdf application/pdf 1492782 no 2014 swe Technology and Engineering 4231015 2014-01-09T08:15:10+01:00 2014-01-17T11:13:56+01:00 2014-01-17T11:13:56+01:00

Today the meat industry is responsible for 10-12% of the total amount of greenhouse gases emitted by humans. During<br /> 2010, USA and Europe consumed approximately 40% of the world’s<br /> total beef production. This by only holding 17% of Earth population.<br /> With a high meat consumption over a small population it’s possible to<br /> affect a larger problem by changing the behavior of this population.<br /> <br /> With insects having the same nutritional content as meat and a 13<br /> times higher protein ECI (Efficiency Conversion Index) than cows. Introducing insects as an alternative to meat in the western countries would contribute to more food and less emissions of greenhouse gases. The problem with introducing edible insects in western countries is the initial disgust people have towards insects. Also in order to be suitable as a alternative to meat the insects can’t be eaten/used in traditional ways.<br /> <br /> In this project the shape of the insects was changed in order to create a raw material that is suitable to the end consumer. By drying the insects and grinding them down to a powder, it’s possible to create a new product; TIP (Textured Insect Protein). This raw material is a dry product that after rehydration (by adding water) is used to create minced meat based dishes. With this shape change it’s possible to bypass the initial disgust people have towards insect, and everyone can now enjoy an environmentally friendly alternative to meat.<br /> <br /> A package for the more specific “cricket protein” was developed to<br /> communicate an environmentally friendly product, by a simple graphical expression (with a stylized picture of a cricket climbing a grass straw on the front) printed on a beige recycable paper. On the back useful information about crickets and the environmentally friendly implications the product will have in the future was shown together with simple instruction on how to use the product in order to create dishes.<br /> <br /> Further development took place and a bowl was created in order to<br /> enhance the possibilities for the user to prepare the cricket protein<br /> dishes. https://lup.lub.lu.se/student-papers/record/4245463/file/4245480.pdf application/pdf 5869809 yes 2013 eng Livestock enteric fermentation Anthropogenic Decay Contraceptives Entomophagy Technology and Engineering Arts and Architecture ISRN LUT-DVIDE/ EX--13/50211--SE 4245463 2014-01-10T14:23:01+01:00 2014-01-10T14:31:54+01:00 2014-01-10T14:31:54+01:00

Even though many Swedes live alone research suggests that dinner party trends (social cooking) will increase - a simple activity, regarding both cost and accessibility, that brings us together with friends and family in our single household life style. I am addressing the scenario of living alone and hosting a dinner party, focusing on compact living as over 80% of the Swedish population live in urban areas.<br /> <br /> The system of cooking is mainly a combination of movement and relaxation; preparing the food and dining. Counter top surface is key when preparing food and small kitchens tend to have a lack of it, especially during a dinner party when several people are preparing food simultaneously. Most kitchens have a table planned in the layout and the table can be used as an additional surface for<br /> preparing food on. Unless it is a bar table, the height of a standard kitchen table is unergonomic to stand by and work on, yet a bar table is not suitable for people in wheelchairs or practical for children and elderly. This debate ultimately led me into designing a height adjustable and space efficient kitchen table.<br /> <br /> BORD V1 is a small sized kitchen table that can host up to 4 persons dining. Half of the surface is height adjustable and when raised the surface is at the same level as a standard kitchen counter top, creating an additional surface on which you can prepare food. The adjusting of the height can easily be achieved by one person. The frame is constructed by box section steel, making it light yet stable and the overall simplistic aesthetics makes it suit a wide range of homes. The oak top is durable for any type of food preparation yet smooth, and by keeping the wooden finish it adds a natural feel to the product. Production is cost effective and<br /> sustainable, because of the long life span of BORD V1 in combination with locally produced materials and easy disassembling for reparation and recycling. https://lup.lub.lu.se/student-papers/record/4246696/file/4246710.pdf application/pdf 15864397 yes 2013 eng Sustainability versatility simplicity and quality Arts and Architecture Technology and Engineering ISRN LUT-DVIDE/ EX--13/50214—SE 4246696 2014-01-10T15:56:02+01:00 2014-08-07T10:16:52+02:00 2014-08-07T10:16:52+02:00

The properties are investigated both by collecting the Swedish rescue services experiences on the matter through a survey and by five full scale tests. The main conclusions of the project is the impact which the amount of openings have on the filling. An opening of eight square meters instead of two makes the filling much faster, because a smaller amount of foam is degraded and the foam is less affected by obstacles. Another outcome is that an interruption during a filling will fail the whole procedure due to the foam stiffens and no more foam can be pushed into the building. It is also found that lack of knowledge and practise with high expansion foam is the main reason for not using it. Although it has positive effects on for example preservation of inventories. https://lup.lub.lu.se/student-papers/record/4249094/file/4249098.pdf application/pdf 2518822 no 2013 swe Lättskum fullskaleförsök frånluftsöppningar fyllnadshastighet lättskumsaggregat räddningstjänst high expansion foam full scale test exhaust openings rate of filling portable foam generator rescue service Technology and Engineering 1402-3504 5442 4249094 2014-01-15T14:35:54+01:00 2014-04-23T15:12:57+02:00 2014-01-15T15:13:02+01:00

studentPublicationsM2 Charlotte Röhfors author PhD, Assistant Professor Daniel Hellström supervisor Packaging Logistics v1000238 department Det här arbetet har genomförts med hjälp av metoden för en fallstudie med flerfallsdesign och en analysenhet. Svenska livsmedelsbutiker är kontexten i arbetet, fallet är sekundärförpackningar för en viss produktkategori och analysenheten är egenskaper hos sekundärförpackningen. Med sekundärförpackning menas den förpackning som fraktas till butik och innehåller flera konsumentförpackningar, oftast en större kartong. Fem olika produktsegment ur Lantmännen Cerealias livsmedelssortiment studerades och fyra olika livsmedelsbutiker deltog i undersökningen. Sekundärförpackningen utvärderades och bedömdes utifrån butikspersonalens perspektiv. Det är sekundärförpackningens prestation i sitt flöde i livsmedelsbutiken som studeras. Datainsamlingen har gjorts med hjälp av intervjuer och den befintliga analysmodellen Packaging scorecard. Viktiga egenskaper hos sekundärförpackningen utifrån butikspersonalens önskemål och värderingar identifieras. Syftet är att fastställa viktiga förpackningsfunktioner hos en sekundärförpackning för de fem olika produktsegmenten pasta, müsli och granola, bönor och linser, fryst bröd samt fryst kyckling. Undersökningen riktar sig till Lantmännen Cerealia och målet är att få en överblick av vad som fungerar respektive inte fungerar när det gäller deras sekundärförpackningar i de olika produktkategorierna. <br /> En sekundärförpacknings betydelse och egenskaper skiljer sig enormt mycket genom hela distributionskedjan, från produktion till slutkonsument. De som har mest kontakt med och påverkas av dess utförande är butikspersonalen. Därför är deras röst viktig att ta del av. Kraven på sekundärförpackningen varierar också beroende på vilken produkt som ska förpackas och fraktas, även dess konsumentförpackning spelar roll. Det handlar om ett samspel mellan produkt, konsumentförpackning och sekundärförpackning. Förslag på förändringar med hjälp av relativt enkla medel har tagits fram. Nya frågor har uppkommit. Arbetet ger en överblick över vilka krav som ställs på en sekundärförpackning och väcker nya frågor och tankar gällande ämnet. https://lup.lub.lu.se/student-papers/record/4249614/file/4332005.pdf application/pdf 2878888 no 2014 swe Sekundärförpackning Packaging scorecard förpackningsfunktioner egenskaper logistik förpackningslogistik Technology and Engineering ISRN 13/5118 4249614 2014-01-16T14:42:04+01:00 2014-02-26T11:11:49+01:00 2014-02-26T11:11:17+01:00

A potential strategy to reduce CO2 emissions is horizontal cooperation between actors on the same level of different supply chains. The strategy opens for cooperation, in for example such non-core activities as distribution and transportation, between companies with a competitive relationship. Larger transport networks increase the possibility to combine optimal routes and consolidate goods. There is also an opportunity for joint facilities which further decrease costs and possibly reduce the total driven kilometres due to more direct routes.<br /> <br /> This master thesis will analyse participating companies’ transport networks and identify collaboration synergies. This to be able to investigate the effects on costs and the environmental impact that horizontal cooperation has. In order to quantify these effects, a constructed case has been built up consisting of two case companies. The case companies are the two largest grocery retailing companies in Sweden - ICA and Coop, with a total market share of around 70%. The purpose of this master thesis has been to test how a dyadic horizontal distribution cooperation effects the CO2 emissions and costs for large grocery retailers in Sweden.<br /> <br /> The transportation networks for each company have been built in the Supply Chain Guru software. The networks have then been combined with joint distribution terminals to investigate how shared distribution facilities influence the total cost and CO2 emissions. Given the underlying assumptions in the models, the results show a potential to reduce distribution costs by 6.2% and reduce CO2 emissions by 1%. These results show a great potential for horizontal cooperation and the potential could increase even more when adding more aspects such as joint distribution planning and supplier collections.<br /> <br /> The analysis requires a state-of-the-art supply chain design software and a software analysis has been carried out. The software is needed to be able to build up large network models and see how changes in the supply chain design affects the environmental impact and the costs. Out of 13 software, six software was possible candidates and out of those two where thoroughly tested. The software analysis showed that out of these two, LLamasoft Supply Chain Guru was the most suitable software and has been used in the analysis.<br /> <br /> Horizontal cooperation opens new innovative ways for companies to act and cut logistics costs and reduce the environmental impact. This master thesis’ purpose was to test how a dyadic horizontal cooperation affect CO2 emissions and logistics cost and shows that horizontal cooperation has a large potential for the two largest companies in the Swedish retail industry. This should invite to more research in the area, including more companies and other industries to truly investigate the vast possibilities of horizontal cooperation. https://lup.lub.lu.se/student-papers/record/4250916/file/4250939.pdf application/pdf 2343290 no 2014 eng Horizontal cooperation retail distribution collaboration joint transportation network Technology and Engineering 4250916 2014-01-20T14:12:49+01:00 2014-01-20T14:37:32+01:00 2014-01-20T14:37:32+01:00

Släkt och familj kan hålla kontakt med varandra via Facebook, tidigare klasskamrater och kollegor är i kontakt via LinkedIn, vänner kan dela länkar på roliga filmer på Youtube och dela vad gör via bilder på Instagram. Sociala medier är en del av social computing, vilket är en kombination av datavetenskap och beteendevetenskap. Sociala medier skapar även möjligheter för företag att nå ut till omvärlden och skapar relationer till sin omgivning. Det kan i många fall anses vara en fördel för företag att finnas på sociala medier, men det finns självklart risker som företagen utsätts för i medierna. Företag får ta ställning om i vilken utsträckning de vill delta på sociala medier, speciellt för företag som anses vara kontroversiella av sin omgivning. Eftersom att de redan för en del människor gör något som anses oetiskt, blir detta ställningstagande mer avgörande än för andra branscher.<br /> <br /> I denna studie undersöker vi 49 stycken företag inom djuphavsborrning genom att se på deras användning av sociala medier. Vi har även intervjuat fem personer som arbetar med eller inom sociala medier. Vi har valt att intervjua dessa personer då vi vill ha representanter som är sakkunniga inom ämnet. Vi vill genom dessa personer samt vår teori lyfta fram det unika med sociala medier. Vi anser att med information från personer med rätt kunskap kan företag skapa en bild av hur sociala medier kan hjälpa deras företag. <br /> <br /> Företagen i vår undersökning förhåller sig väldigt försiktigt till sociala medier. Genom våra utomstående ögon visar det låga deltagandet på ett aktivt ställningstagande att inte delta då företagen inte ser att de drar tillräckligt stora fördelar av sociala medier. De risker men även de engagemang och resurser som sociala medier kräver, behåller företagens passiva ställning. De kontroversiella företagen vill ligga i periferin och inte vara drivande i en offentlig debatt där det kan hända att de blir en frontfigur för en hel bransch.<br /> <br /> Genom att se hur ett antal företags relationer till sociala medier ser ut och genom att få personer som arbetar med sociala mediers synpunkter på deras användning, kan en fördjupad studie av kontroversiella företags användning av sociala medier ske. Det är ett sätt att bevisa för företagen att användning av sociala medier är möjlig, även för kontroversiella företag. https://lup.lub.lu.se/student-papers/record/4251375/file/4251376.docx application/vnd.openxmlformats-officedocument.wordprocessingml.document 376488 LU/LTH access 2014 swe Sociala medier Social computing Kontroversiell B2B Risker Möjligheter Technology and Engineering 4251375 2014-01-21T12:30:23+01:00 2014-02-10T15:00:06+01:00 2014-02-10T15:00:06+01:00

To further improve safety and accessibility of the existing roads, widening of roads can be performed. The purpose of this thesis is to identify and summarize different variants of construction for road widening, using the existing data and experiences regarding widening. In order to obtain the necessary information a literature survey, two field studies and 12 interviews, with relevant project managers, were performed. The same type of questionnaire was used during all the interviews. This questionnaire contained questions answering in what phase of the construction process the road is in, which technical solution was applied and which studies were made etc. Two interviews with experienced geotechnical engineers were also performed to gain more knowledge within the topic. This thesis includes three different technical solutions. These three are widening with natural material including milling and admixing, stabilization and expansion of reinforcement. It also contains information concerning the important factors that should be considered during widening. The technical solutions, which the report refers to, are summarized in a chart. This presents the pros and cons of each technical solution. A compilation of the technical solutions showed that there are two methods to prefer. These two are widening with reinforcement and admixing. The thesis states the importance of proper pre-investigations and that thorough checks are made throughout the construction phase of a project. It is also of importance to think long term and from a life cycle perspective. https://lup.lub.lu.se/student-papers/record/4253674/file/8961710.pdf application/pdf 977323 no 2014 swe technical solution milling admixing widening reinforcement life cycle perspective Technology and Engineering 4253674 2014-01-23T00:00:00+01:00 2018-10-18T10:28:16+02:00 2014-01-24T00:00:00+01:00

This shallow terminal lake has been designated as a Biosphere Reserve by UNESCO and a National Park under the 1971 Ramsar Convention. Currently, the entire lake’s watershed is threatened due to its abrupt desiccation of more than 50% of its surface area and the concomitant increase of salinity during the last two decades. As the rapidly declining eco-environmental conditions have serious impacts on the socio-economy of the whole region, the drying of the lake is considered as a national threat. In light of the above, within the present study a holistic hydroclimatic analysis of the lake is conducted. The principal hypothesis of this research is that ‘during the recent years (1996-2012), there has been an intrinsic change in the dynamic of the lake water level mainly due to human activities which has had deteriorating impacts on the lake and its entire basin’. Therefore, water level variations, as the eco-hydrological indicator of this basin, are compared for the two periods of natural and anthropogenically intervened i.e. 1966-1995 and 1996-2012, respectively. The result of Mann-Kendall trend test, which has been used to identify the changes, shows that there is a unique decreasing trend of about -0.25 m/yr in average during the recent period of 1996-2012. Further, the nonlinear chaotic analysis of Correlation Dimension Method is employed in order to investigate the underlying dynamic of water level oscillations. The correlation exponent has decreased from 3 during the period of 1966-1995 to 2 during 1966-2012 implying that 1 governing variable of the lake’s dynamic is missing! Pursuing the major cause of the recent desiccations, a multiple linear regression model is made based on the standardized monthly anomalies of the lake water level during 1966-1995 and the influencing teleconnection indices as predictors. For the months March and April as high season months and December as a low season month, water level variations have been modeled. Comparing modeled and observation time series shows that climate variability could explain about 35-40% of water level variations in the 1st period. For the 2nd period, nonetheless, only 11-14% of the variations in the high season (i.e. March and April) and 35% in December (low season) could be explained by climate variability i.e. natural causes. In view of the above and alluding to fact that extensive human activities in terms of climate change, land use changes, groundwater withdrawals, causeway, dam and other water diversion projects have occurred or have been intensified during the 2nd period, it could inductively be concluded that human activities are the major cause for the recent depletion of the lake. This result has been confirmed by previous paleolimnological studies as well. Afterwards, the salinity of the lake is modeled by means of regressions and the current salinity level of the lake is obtained to be more than 360 g/l. Eventual ecological consequences of the ongoing deteriorating conditions on the whole basin are discussed. Finally, after the critical review of previously proposed solutions, the project is closed by suggesting plausible possibilities for the restoration of the lake and its watershed towards a sustainable eco-socio-economic state, in terms of short- and long-term measurements. https://lup.lub.lu.se/student-papers/record/4253926/file/4934284.pdf application/pdf 3691970 no 2013 eng Hypersaline lake Urmia Lake Artemia Urmiana Nonlinear time series analysis Chaos Theory Correlation Dimension Method Man-Kendall trend test Trend Climate Variability Hydroclimatology Salinity Secondary Salinization Regressions Technology and Engineering 1101-9824 13/5012 Sweden’s Best Master Thesis of the Year (2013) in Environmental Sciences by Ramböll Company Revised, January 2015 Examiner: Magnus Persson 4253926 2014-01-24T11:31:08+01:00 2019-03-29T10:16:27+01:00 2014-02-11T10:33:41+01:00

Accidents do occur in spite of actions taken to prevent them from happening. The energy-barrier philosophy is the governing principle within the Norwegian offshore industry. The paradox with that philosophy is that the construction of additional barriers may increase complexity within the system. Risk may be seen as an emerging property of complex systems, yet little attention is paid to complex interactions in<br /> barrier systems. The Petroleum Safety Authority Norway (PSA) has therefore raised the matter of dependencies within barrier systems during 2013 to increase awareness of their implications. The governing energy-barrier philosophy relies on linear reasoning and does therefore not provide tools for the interpretation of complex and non-linear interactions. Hence the purpose of this thesis is to apply a different method to interpret interdependencies in a barrier system on an offshore platform and then evaluate the application of that method. The purpose is also to see if the PSA prioritizes an essential issue. https://lup.lub.lu.se/student-papers/record/4255227/file/4255234.pdf application/pdf 661922 no 2013 eng Barriers complexity dependencies FRAM normal accidents offshore barriärer komplexitet beroenden normala olyckor Technology and Engineering 1402-3504 5447 4255227 2014-01-27T14:32:52+01:00 2014-03-10T10:40:47+01:00 2014-01-27T14:49:56+01:00

Therefore, events in two small municipals were analyzed. The report also aims to examine if risk and vulnerability analysis is an appropriate tool for smaller municipals to work with social risks. The analysis shows that social risks are present also in smaller municipals and that they therefore should consider these in order to increase community safety. Further, the analysis shows that risk and vulnerability analyzes are partly a suitable tool for smaller municipals to work with social risks. https://lup.lub.lu.se/student-papers/record/4255235/file/4255239.pdf application/pdf 1038987 no 2013 swe Social risks risk and vulnerability analysis arson hate crime abuse of drugs risk factor protection factor sociala risker risk- och sårbarhetsanalys anlagd brand hatbrott missbruk av droger riskfaktor skyddsfaktor Technology and Engineering 1402-3504 5433 4255235 2014-01-27T14:38:46+01:00 2014-03-10T10:40:47+01:00 2014-01-27T14:49:30+01:00

Geotechnical investigations are made to determine the soil properties and one method of doing so is to perform borehole drillings. Such drillings are expensive and unfortunately it’s not always known if similar procedures have been performed in the surroundings. A geotechnical drilling is interpreted by a geologist that clearly would benefit from knowing the results from previous drillings in the area. Thus, there is a common interest in centralized storage of such data.<br /> <br /> Sweco GeoAtlas is a GIS software for managing geotechnical data which also enables advanced geological analysis. Its usage requires installation in a desktop environment and rather good acquaintance of the system. This master thesis use Sweco GeoAtlas as a case study to investigate how presentation of geotechnical data can be performed on the web.<br /> <br /> Existing mapping services for managing geotechnical data as well as other services for displaying quantitative point data have been studied to determine their strengths and weaknesses. The Geological Survey of Sweden has a newly launched application with relevant purposes but it’s still in an early stage. The Geology of Britain Viewer is a good example of how a web application for geotechnical data can look like.<br /> <br /> The requirement specification for the web application contains features stretching from basic point interaction to the implementation of 3D functionality. All of the requirements haven’t been fulfilled due to various reasons but they are all brought up for discussion.<br /> <br /> The starting point for the prototype in the case study was to solve the problem with displaying quantitative data. Because of this, the web mapping library Leaflet was chosen since it has a well-functioning cluster plugin. Other choices of technology consist of Open Street Map as base map and a dynamic SVG for displaying stratigraphic profile images.<br /> <br /> The conclusion of the thesis is that it’s possible to move basic interaction with geotechnical borehole drillings to a web environment. Rather than a complete web-GIS the application would instead be an environment to view the data. The target audience of the web application are GeoAtlas users that aren’t experts and therefore this could be considered as a reasonable division. https://lup.lub.lu.se/student-papers/record/4255475/file/4255483.pdf application/pdf 3242302 no 2014 swe geotechnical investigations point clustering Physical Geography and Ecosystem analysis WEB-GIS borehole scans leaflet Technology and Engineering 12 https://lup.lub.lu.se/student-papers/record/4255475/file/4255487.pdf application/pdf LU/LTH access External supervisors: Karin Neland, SWECO Position Malmö and Peter Rothstein, SWECO Position Malmö 4255475 2014-01-27T16:51:48+01:00 2014-01-27T17:38:31+01:00 2014-01-27T17:38:31+01:00

The purpose of the first experiment was to examine whether people make the same choice of exits in Virtual Reality as in real evacuation experiments in simple environments with flashing lights. In the secound experiment subjects were faced with three different situations where they could choose between two exits with flashing lights in red or green. In the first experiment 30 subjects participated and the result showed that there was no significant difference between the real and virtual experiment. In the secound experiment 40 subjects participated and the results showed that 35 subjects consistent chose exits with green lights and that the exits with green lights were perceived as the most secure choice. https://lup.lub.lu.se/student-papers/record/4276230/file/4276233.pdf application/pdf 1904377 no 2013 swe Fire evacuation behaviour exit choice green and red flashing lights experiments Virtual Reality validation Unity CAVE brand utrymning beteende vägval gröna och röda blinkande ljussignaler försök validering Technology and Engineering 1402-3504 5440 4276230 2014-01-29T11:55:59+01:00 2014-03-10T10:40:47+01:00 2014-01-29T12:00:47+01:00

Spectracure AB has developed a system for real time monitoring of dose parameters during IPDT treatment of prostate cancer using bare-end fiber tips. One of the parameters that is monitored is the effective attenuation coefficient, mu_{eff}, and the goal of this thesis is to study how well this parameter can be evaluated with cylindrical fibers. For this purpose a digital 3D model with a FEM solver is used to simulate experimental data and an evaluation program is implemented in Matlab. This program assesses the optical properties at each fiber given the simulated fluence rate measured in the digital model. The program is shown to work well in the ideal homogeneous case with with normal optical properties, where the error is only 0.35 % between assessed mu_{eff} and the actual mu_{eff} from the simulated experimental data.<br /> <br /> Normal errors in fiber positioning impose an error of about 4.48% between evaluated and actual mu_{eff}. When a heterogeneous tissue model is used to mimic the true condition in vivo, larger errors are seen. In the worst case giving an error of 22.7% between evaluated and actual mu_{eff}. It was otherwise difficult to draw definite conclusions from the results of the evaluation under heterogeneous conditions. Further tests on in-vivo and incorporating the cylindrical diffusers in the complete SpectraCure system would give a more conclusive answer. It is shown however that it is possible to implement an evaluation software for cylindrical diffuser fibers, that it is possible to obtain a good light distribution profile and that it is accurate in the ideal case. https://lup.lub.lu.se/student-papers/record/4279665/file/4279686.pdf application/pdf 3715665 LU/LTH access 2013 eng IPDT prostate cancer cylindrical diffuser medical optics Spectracure photodynamic therapy tissue optics PDT photosensitizer Biology and Life Sciences Medicine and Health Sciences Technology and Engineering 4279665 2014-01-30T16:50:40+01:00 2015-12-14T13:32:33+01:00 2014-01-31T11:09:51+01:00

studentPublicationsH2 Elin Backman author 4222152 Åsa Ek supervisor Ergonomics and Aerosol Technology v1000237 department Det finns många uppfattningar av hur risk definieras och den mest traditionella definitionen av risk är sannolikheten för att en oönskad händelse ska inträffa multiplicerat med konsekvensen av händelsen om den inträffar. Dock har denna tekniska definition av risk blivit starkt ifrågasatt de senaste decennierna då många menar att sociala, psykologiska och kulturella faktorer måste beaktas. Människors olika värderingar och riskperceptioner gör att en risk kan uppfattas väldigt olika.<br /> <br /> Sårbarhet är nära relaterat till risk då det uppstår till följd av ett visst riskscenario. Definitionen av sårbarhet är de problem som uppstår i ett system när detta utsätts för oönskade händelser samt de problem systemet får när verksamheten ska återupptas efter att sådana händelser har ägt rum.<br /> <br /> Metoder som riskbedömningar, riskanalyser samt risk- och sårbarhetsanalyser (ROS-analyser) blir allt vanligare för att på förhand kunna upptäcka och analysera risker och sårbarheter med en planerad åtgärd i samhället. Riskbedömningar består av en riskanalys och en riskvärdering. Riskanalysen syftar till att bestämma risker samt att värdera sannolikheten och konsekvensen för att en oönskad händelse ska inträffa. Riskvärderingen utgörs av den fas där resultaten från riskanalysen jämförs med uppsatta acceptkriterier för tillåten risk och förslag på riskreducerande åtgärder ges om risken bedöms vara för hög. En ROS-analys består av, som går att avläsa av namnet, av en riskanalys och en sårbarhetsanalys och har alltså som syfte att identifiera och analysera både risker och sårbarheter.<br /> <br /> Detta examensarbete har utförts i samarbete med Sweco Norge AS, vilka ofta utför riskbedömningar, riskanalyser eller ROS-analyser i samband med de uppdrag som de tilldelas. Dock saknar Sweco Norge AS i dagsläget en generell struktur för hur dessa ska genomföras och en önskan om förbättring finns. Även rutiner för uppföljning av åtgärder i projekten behöver förbättras.<br /> <br /> Syftet med examensarbetet var att ta fram en standardmall för hur riskbedömningar skall utformas på Sweco Norge AS. Eftersom en riskbedömning består av en riskanalys och en riskvärdering, går mallen även att tillämpa då en riskanalys ska upprättas. Ett avsnitt om sårbarhetsanalyser finns också med i mallen för att den ska vara möjlig att använda vid utformning av ROS-analyser. Därmed kan mallen användas oavsett om en riskbedömning, riskanalys eller ROS-analys efterfrågas.<br /> <br /> Metoder som har använts för att kunna besvara examensarbetets frågeställningar är litteraturstudie, intervjustudie, dokumentanalys av interna respektive externa rapporter samt mailkontakt med uppdragsledare inom Sweco. Viktig litteratur i litteraturstudien är ”NS 5814: Krav til risikovurderinger”, som är en standard för hur riskbedömningar ska utföras och dokumenteras i Norge. Intervjustudien innehåller intervjuer med fem personer som alla arbetar med risk i Sweco Norge AS. Dokumentanalysen av interna rapporter innebar en granskning av 21 rapporter (riskbedömningar, riskanalyser och ROS-analyser) gjorda av Sweco Norge AS medan de externa rapporterna utgjordes av fyra rapporter från olika företag som arbetar med liknande uppdrag som Sweco. Mailkontakten med uppdragsledare inom Sweco var för att undersöka om de fått någon feedback från kunderna efter att de levererat rapporterna och helt enkelt för att undersöka om kunderna varit nöjda.<br /> <br /> De viktigaste slutsatserna med detta examensarbete är:<br /> • Viktigt att skilja på begreppen riskbedömning, riskanalys och ROS-analys. Dessa begrepp betyder inte samma sak. Sårbarheter ska redovisas om rapporten kallas för ROS-analys.<br /> • Måste förbättra eller snarare lägga till avsnitt om osäkerhet och känslighet – presentera osäkerheter samt redovisa hur osäkerheterna kan påverka resultatet och därmed även ett eventuellt beslut (känslighetsanalys). Osäkerhet och känslighet måste få större plats i Sweco Norge AS´s rapporter.<br /> • En gemensam mapp som alla anställda har tillgång till bör upprättas, så att alla riskrapporter kan dokumenteras i denna mapp. Dokumentation är viktigt för att Sweco Norge AS´s rapporter ska få en mer gemensam struktur. Anställda vill dokumentera rapporterna på ett gemensamt ställe, så att man kan lära av varandra.<br /> • Uppföljning av åtgärder bör bli ett vanligare moment. Vem som är ansvarig för att uppföljningarna görs samt när de ska göras ska anges i rapporten. https://lup.lub.lu.se/student-papers/record/4285827/file/4285913.pdf application/pdf 1996338 no 2014 swe Riskbedömning riskanalys risk- och sårbarhetsanalys ROS-analys Sweco risk sårbarhet.

The defined best practices will later be implemented in the corporation’s market companies globally.<br /> The methodology of the project has been to benchmark organizations with similar type responsibilities and work. The research design has mainly been divided into a quantitative analysis (analyzing sales data) and a qualitative analysis (interviews).<br /> The challenge has been to benchmark organizations that operate in different economical and political climates (macro economy) while their industries (micro economy) differ a lot as well. Therefore a benchmarking model has been developed to take these external factors into consideration. Thereby a relevant and trustworthy benchmarking output was achieved.<br /> Two best practices were found to impact the performance of an organization (sales) positively and significantly. These best practices have been communicated to the company with a suggested implementation plan.<br /> While uncovering the best practices, it has been found that organizations that perceive their competition to be intense tend to formulate a strategy. The existence of a strategy drastically improves the organization’s performance (sales). If the strategy is supported with relevant and related activities, the performance increases even further. https://lup.lub.lu.se/student-papers/record/4286447/file/4286449.pdf application/pdf 1888841 no 2014 eng internal bench marking best practice spare parts standard components Technology and Engineering 14/5480 4286447 2014-02-06T13:50:07+01:00 2014-02-06T14:01:45+01:00 2014-02-06T14:01:45+01:00

The work is conducted from a flow-based perspective where dependencies and influences between actors are connected through flows. This report proceeds earlier work conducted at Lund University and also aims at evaluating the concept of flows in dependency analyses. An existing method for dependency analysis is chosen, evaluated and integrated with the method for mapping. It was concluded that the concept of flows must be further analyzed before it is used, however several criteria have been developed regarding the mapping of actors in dependency analysis. https://lup.lub.lu.se/student-papers/record/4293462/file/4293479.pdf application/pdf 1704992 no 2013 swe Mapping Aggregation Dependency Impact Dependency analysis Risk and vulnerability analysis Flow Snowballing Kartläggning Aggregering Beroende Påverkan Beroendeanalys Risk- och sårbarhetsanalys Flöde Technology and Engineering 1402-3504 5434 4293462 2014-02-07T14:08:27+01:00 2014-03-10T10:40:47+01:00 2014-02-07T14:14:58+01:00

The task of automatically finding and identifying objects in an image is challenging in the extreme. By looking at the problem from a new angle and including additional information beside the visual, the problem becomes less ill posed.<br /> <br /> In this thesis we investigate how the addition of text annotations to images affects the classification process. Classifications of different sets of labels as well as clusters of labels were carried out. A comparison between the results from using only visual information and from also including information from an image description is given. In most cases the additional information improved the accuracy of the classification.<br /> <br /> The obtained results were then used to design an algorithm that could, given an image with a description, find relevant words from the text and mark their presence in the image. A large set of overlapping segments is generated and each segment is classified into a set of categories. The image descriptions are parsed by an algorithm (a so called chunker) and visually relevant words (key-nouns) are extracted from the text. These key-nouns are then connected to the categories by metrics from WordNet. To create an optimal assignment of the visual segments to the key-nouns combinatorial optimization was used. The resulting system was compared to manually segmented and classified images.<br /> <br /> The results are promising and have given rise to several new ideas for continued research. https://lup.lub.lu.se/student-papers/record/4317091/file/4317099.pdf application/pdf 4223060 no 2014 eng Mathematics and Statistics Technology and Engineering 1404-6342 2014:E5 LUTFMA-3258-2014 4317091 2014-02-18T12:57:27+01:00 2014-05-27T11:18:40+02:00 2014-05-16T17:05:01+02:00

The neurological disease is characterised by episodes of neural hyperactivity (seizures) and neural synchronization that can have behavioural manifestations such as convulsions. Anti-epileptic drugs (AEDs) can be used for treating most cases of epilepsy, but since especially temporal lobe epilepsy (TLE) has proven to be drug resistant, there is still a need to develop novel treatment methods. The research towards such new treatments requires animal models that mimic the pathology of the human disorder. In this project, optogenetics is used in evoking seizure-like afterdischarges (ADs) in anaesthetised mice by stimulating the CA1 region of the hippocampus. The mice are transgenic, expressing channelrhodopsin 2 – green fluorescent protein (ChR2-GFP) under the Thy1 promoter. An optrode is constructed and used to both stimulate with 463 nm light in 10 Hz pulses and to record an intracranial electroencephalogram (EEG). The tissue response and amount of ADs that follows a light stimulation train is evaluated. Also, spontaneous activity is assessed by calculating the burst suppression rate (BSR). Isoflurane and ketamine anaesthesia is compared and it is concluded that ketamine at the dose of 80mg/kg blocks the development of ADs following a stimulation train. On the other hand, the isoflurane anesthetised animals developed ADs which seemed to escalate in a kindling like manner. https://lup.lub.lu.se/student-papers/record/4317165/file/4317166.pdf application/pdf 2925523 no 2013 eng optogenetics epilepsy channelrhodopsin isoflurane ketamine EEG kindling temporal lobe epilepsy TLE seizure optrode hippocampus Thy1 Technology and Engineering Medicine and Health Sciences 4317165 2014-02-18T16:44:23+01:00 2015-12-14T13:32:33+01:00 2014-03-26T13:26:23+01:00

One of the generator side problem in this is to meet the power requirement while not wasting unnecessary power, thus keeping the cost down, which must be done while the frequency is kept in a suitable range that will not damage any equipment connected to the power grid. It would theoretically be most logical to have a centralized controller that gathers the full networks data, calculates the control signals and adjusts the generators. However in practice this is not practical, mostly due to distance. The transmission of sensor data to the controller and the transmission of control signals to the generators would have to travel far, thus taking up to much time before the generators could act.<br /> <br /> This paper presents a distributed model predictive control based method to control the frequency of the power network. First, an augmented matrix model predictive controller is introduced and implemented on a two homogeneous subsystems network. Later the control method is changed to a state space model predictive controller and is then utilized on a four heterogeneous subsystems network. This controller implementation also includes state<br /> observers by Kalman filtering, constraints handler utilizing quadratic programming, and different connection topology setups to observe how the connectivity affects the outcome of the system.<br /> <br /> The effectiveness of the proposed distributed control method was compared against the corresponding centralized and decentralized controller implementation results. It is also compared to other control algorithms, specifically, an iterative gradient method, and a model predictive controller generated by the MATLAB MPC Toolbox. The results show that the usage of a distributed setup improves the outcome compared to the decentralized case, whilst keeping a more convenient setup than the centralized case. It it also shown that the level of connectivity for a chosen network topology matters for the outcome of the system, the results are improved when more connections exists. https://lup.lub.lu.se/student-papers/record/4317314/file/4317341.pdf application/pdf 7578980 no 2013 eng Technology and Engineering 0280-5316 ISRN LUTFD2/TFRT--5931--SE https://lup.lub.lu.se/student-papers/record/4317314/file/4317327.pdf application/pdf no 4317314 2014-02-19T11:12:59+01:00 2014-02-19T11:59:52+01:00 2014-02-19T11:59:52+01:00

In most outdoor environments this problem was solved by the introduction of the Global Positioning System (GPS). In indoor or suburban areas however, the GPS signals are often too weak to enable a reliable position estimate. Instead, other techniques must be utilized to provide accurate positioning. One of these is trilateration based on WiFi signal strengths. This is an auspicious technology to use partly because of the large number of access points (APs) in our everyday environment, and partly due to the possibility of measuring signal strength with a normal smartphone. The technique is further enabled by the move to include transmitters at 2.4 as well as 5 GHz in modern APs, providing a better basis for accurate position estimations. Furthermore, the motion sensors present in today’s smartphones are accurate enough to provide a short-time estimate of the user’s movement with high accuracy. In this thesis, both of these technologies are used to develop an accurate method for indoor positioning, and the contributions can be summed up into two points.<br /> <br /> The first contribution is an investigation of the behavior of two WiFi frequencies, 2.4 and 5 GHz, where their time dependent noise is proven to be almost uncorrelated with each other. This is then exploited to develop aWiFi-only trilateration algorithm by the use of a particle filter (PF), where the only restriction is that the locations of the APs need to be known.<br /> <br /> The second contribution is adding an accelerometer and a gyroscope to the algorithm, to provide a more accurate estimation. A step counter is developed using the accelerometer, and the gyroscope detects changes in heading while the WiFi signal strengths give information about the position. This makes it possible to alongside the position also estimate both heading and step length, while still keeping the only restriction of knowing the AP locations. The resulting algorithm produces position estimates with a mean error less than two meters for a specific use case, and around three meters when a more lenient user behavior is allowed. https://lup.lub.lu.se/student-papers/record/4317328/file/4317329.pdf application/pdf 2864956 no 2014 eng Technology and Engineering 0280-5316 ISRN LUTFD2/TFRT--5932--SE https://lup.lub.lu.se/student-papers/record/4317328/file/4317331.pdf application/pdf no 4317328 2014-02-19T11:39:35+01:00 2014-02-19T13:48:05+01:00 2014-02-19T13:48:05+01:00

One proposed way of doing this is by having vehicles travelling at close distances to reduce the air drag, and thereby reducing their fuel consumption. This thesis address the platooning problem on model-scale vehicles as they are a desirable demonstration platform since they can be driven indoors.<br /> <br /> This thesis considers the implementation and evaluation of the longitudinal control of a model-scale vehicle platoon where Model Predictive Control is utilised. The concept of platooning on real full-size vehicles is briefly discussed and some of its benefits are described. The thesis then discusses and evaluates what sensors are necessary to equip the model vehicles with and how to implement them, in addition to a discussion and evaluation of inter-vehicular communication in an indoor environment is provided. Then, based on the available sensors, a heuristic feedback controller and a model-based controller is designed as distance controllers, as well as a feedback controller used for speed control, and then connected in a cascading structure. The two controllers are then evaluated in simulations based on different<br /> scenarios and finally results from a working implementation on the model-scale vehicles are presented.<br /> <br /> The end results from this thesis are a demonstration platform of two model-scale electrical vehicles as well as two different distance control algorithms both based on using the cruise control developed in the vehicles. https://lup.lub.lu.se/student-papers/record/4317334/file/4317335.pdf application/pdf 8609493 no 2014 eng Technology and Engineering 0280-5316 ISRN LUTFD2/TFRT--5933--SE https://lup.lub.lu.se/student-papers/record/4317334/file/4317337.pdf application/pdf no 4317334 2014-02-19T11:50:12+01:00 2014-02-19T13:47:15+01:00 2014-02-19T13:47:15+01:00

The project was conducted in collaboration with ArjoHuntleigh AB, a company based in Malmö, Sweden. ArjoHuntleigh develops integrated healthcare solutions for people with low mobility and thereto related problems.<br /> <br /> The report describes the development and design of an accessory for the Carevo shower trolley, a newly launched product in the ArjoHuntleigh product line of hygiene systems. The accessory is intended to facilitate handling of loose objects involved in the showering process using the Carevo.<br /> <br /> In order to obtain valuable knowledge about the healthcare business and identify the relevant needs of the Carevo users, research was conducted. The research involved a pre-study, observation and contextual interviews with the caregivers in their environments and interviews with sales representatives of ArjoHuntleigh in foreign countries.<br /> <br /> Based on the identified needs, a range of product concepts were generated. Using sketch prototypes the concepts were tested and refined until only one concept was chosen.<br /> <br /> The final concept is a holder mainly intended for facilitating the handling of bottles used in the shower process using Carevo. The holder can be attached to different parts of the Carevo, depending on the requirements of the user. When not used, it can be stored on a flat surface, e.g. in a cabinet or on a sink.<br /> <br /> A prototype of the final concept was produced and tested in order to evaluate how well the concept meets the needs of the target users. Suggestions for further improvements to the concept are provided, as well as brief discussions about producibility and material choice. https://lup.lub.lu.se/student-papers/record/4317348/file/4317371.pdf application/pdf 4758807 no 2013 eng Product Design Product Development ArjoHuntleigh Healthcare Hygiene System Technology and Engineering 4317348 2014-02-19T12:43:12+01:00 2014-02-26T10:50:11+01:00 2014-02-26T10:50:11+01:00

Ett sådant är Augustenborg, Malmö, där man genom anläggning av ett fullskaligt, öppet dagvattensystem lyckats reducera avrinningen med 70% samt minska över-svämningarna i området. <br /> Att på ett hållbart sätt hantera dagvatten i urbana miljöer kan resultera i samhällsekonomiska vinster. Dock finns i dagsläget begränsat med studier kring värdering av de sociala samt miljömässiga effekter som ett öppet dagvattensystem bidrar med. <br /> I detta arbete har en subjektiv metod utvecklats för utvärdering av hållbarheten hos element från dagvattensystemet. Utvärderingen skedde genom poängsättning med skala 0-10 för elementens uppfyllelse på tekniska, miljömässiga, ekonomiska samt sociala aspekter. Slutligen viktades samtliga aspekter lika och ett hållbarhetsindex skapades.<br /> Elementen från den öppna dagvattenhanteringen i Augustenborg fick följande hållbarhetsindex: våta dagvattendammar 6.9, infiltrationsytor 5.8, öppna dagvatten-kanaler 5.1 samt gröna tak 5.0. Motsvarande alternativa mer traditionella lösningar hade samtliga ett hållbarhetsindex på under 4.0. Med ledning av denna metod kan slutsatsen dras att öppna dagvattensystem är en mer hållbar lösning än traditionella lösningar. https://lup.lub.lu.se/student-papers/record/4331124/file/4331186.pdf application/pdf 3109213 LU/LTH access 2014 swe Technology and Engineering 1101-9824 12/5016 Examiner: Linus Zhang 4331124 2014-02-25T10:37:07+01:00 2019-03-29T13:57:05+01:00 2014-03-07T14:35:59+01:00

With conventional methods the forward kinematics, inverse kinematics and the kinematics for the velocities and accelerations of the robot are modelled. The forward dynamics, calculating the generated motor torques, of the robot is modelled with MapleSim and code generation of this model, to be implemented in the software from B&amp;R<br /> Automation and used online during control, is used. In the software from B&amp;R Automation, B&amp;R Automation Studio, the kinematic model, path trajectories for the TCP with polynomial functions, an interface between the software and a PC and programs for communicating with the drives are also implemented together with a main program. To simplify, analyze and calculate equations Maple is used.<br /> <br /> Experiments using the generated torque are made for comparison with the model and to improve it. The model is improved by measuring the friction torque and the torque caused by the inertia of the motor, a gear and one robot arm.<br /> <br /> Because of the parallel structure of the robot the generated dynamic equation consists of complex differential equations which can overload the PLC during solving. To ensure stability of the dynamic model a second dynamic model with constraint stabilization is generated for use during slower movements. Despite the risk of starvation of the PLC the robot is moved at 10 g acceleration with good result comparing calculated and actual torque. Without using the desired feedforward from the dynamic equations, but instead using a simpler less dynamic feedforward method, the robot is accelerated at 16 g. https://lup.lub.lu.se/student-papers/record/4332966/file/4332967.pdf application/pdf 1941576 no 2013 eng Technology and Engineering 0280-5316 ISRN LUTFD2/TFRT--5929--SE https://lup.lub.lu.se/student-papers/record/4332966/file/4332969.pdf application/pdf no 4332966 2014-02-26T15:38:37+01:00 2014-03-03T11:28:32+01:00 2014-03-03T11:28:32+01:00

Kraftverkstunnlar är alltid vattenfyllda, vilket innebär att inspektioner är svåra att genomföra. Driftstopp av anläggningen för inspektioner anses vara för kostsamma, vilket innebär att få har överblick över konditionen på de svenska kraftverkstunnlarna samt hur beständiga de är.<br /> Syftet med detta examensarbete är att studera åldringsfenomen och nedbrytnings‐ processer i kraftverks – hur tunnlarna åldras och bryts ned. För att göra detta krävs kunskap om hur tunnlarna är konstruerade och utförda, vilket omfattar både tunneldrivnings‐ och förstärkningsmetoder. Nedbrytning av tunnlarnas förstärkningar, med speciellt fokus på korrosion av bultar, och förändrande egenskaper hos bergmassan är två centrala faktorer i arbetet. Förhoppningen är att detta examensarbete skall kunna utgöra ett underlag för planering av fortsatt drift‐ och underhållsarbete men även för fortsatt forskning.<br /> Resultatet från fallstudierna indikerar att tre rasmekanismer är vanligt förekommande: Svällande lera, glidning i svaghetszon med omvandlingsprodukt samt variationer i det hydrostatiska trycket inne i tunneln. Dessa rasmekanismer utvecklas vanligtvis relativt kort efter driftsättning, vilket kan bero på att fel förstärkningsmetod använts eller på att förstärkningen varit underdimensionerad.<br /> Litteraturstudien avslöjade att inget av de 26 studerade tunnelrasen berott endast på att bergbultar korroderat och mist sin bärförmåga. Den visade också visar att ingjutna bergbultar som är monterade på rätt sätt har god beständighet och generellt utsätts för små korrosionsangrepp. Dock har uppgifter från besök och samtal på olika vattenkraftverk indikerat att vissa kraftverkstunnlar endast är förstärkta med tillfälliga bultar. Dessa tillfälliga bultar skulle kompletteras med ingjutna bultar i ett senare skede, vilket inte gjorts. De tillfälliga bultarna utgör således en okänd risk för kraftverkstunnlarnas beständighet och stabilitet. https://lup.lub.lu.se/student-papers/record/4354174/file/4354195.pdf application/pdf 3559590 no 2013 swe Kraftverkstunnlar tunnelras beständighet åldringsfenomen bergbultar korrosion Technology and Engineering TVTG—5131 4354174 2014-03-07T14:13:17+01:00 2014-09-04T08:30:24+02:00 2014-03-10T10:41:49+01:00

The rapid urbanization process in Africa is a major challenge for politicians, urban planners and society in general. The archipelago of Zanzibar in Tanzania is in the middle of this process. Traditionally, low and middle income families live in Swahili houses, houses characterized as low rise houses, usually one floor, resulting in urban environment with a horizontal growth instead of vertically. Because this group of population is very voluminous the problem is reflected on the occupation of very large areas of land used for housing. Large parts of the local families have not responded positively to the attempts to deal with density issues increasing the number of homes in low-rise multi-storey buildings. The urbanization process is so fast that the different needs seem to compete with each other, and therefore priorities must be made. We visited the island during the month of April 2012 and we spent three weeks in Zanzibar, living with a local family to make the field study. Apart from observations, and interviews with locals, town planners and experts on the fields, we conducted a survey questionnaire with residents divided in two groups: one living in Swahili houses and a second living in low-rise multi-storey houses. The purpose of this survey was to understand and to be able to analyze the situation, but also to see what opportunities exists to develop neighborhoods and residential areas, so that they better meet the need for sustainable living now and in the future. We also did a climate analysis due to the fact that the indoor climate is important for us humans to thrive and feel well. https://lup.lub.lu.se/student-papers/record/4357652/file/8961711.pdf application/pdf 3825386 no 2014 eng urbanization density sustainable housing development swahili house zanzibar Technology and Engineering 4357652 2014-03-03T00:00:00+01:00 2018-10-18T10:28:18+02:00 2014-03-11T00:00:00+01:00

The reasoning why powder metallurgy and particulate materials processing is chosen as a topic for this thesis is because of the potential to minimize the manufacturing waste. Instead of utilizing wasteful cutting and grinding processing steps to gain the final shape, powder processing aims to minimize the waste by producing near net shaped products. These in turn can be sintered to form comparatively strong components with less waste and often faster processing times. By sintering the component less heat is needed for formation which reduces production costs.<br /> <br /> Because of this a fundamental knowledge regarding which powder products can be used for the industry is needed. The iron aluminide system has been seen as a viable candidate in high temperature alloy components which also are resistant to oxidation as well as sulphurization. The study focuses on the influence of particle size and heating rate on the intermetallic phase formation during reactive sintering. Differentiations during sintering which will be analyzed are: exothermic behavior, phase changes, onset temperature of the exothermic reaction, and possible density changes.<br /> <br /> This thesis shows thermal data which exhibit a single exothermic behavior for when sufficiently small iron particles is used for self-propagating high temperature synthesis. This is differentiated from the two peak exothermic reaction which can be seen in other studies for coarser particle size. Both energy-dispersive x-ray spectroscopy as well as x-ray diffraction were used to characterize phase changes post processing. It was identified that for finer particle mixtures a near complete FeAl phase could be achieved with a heating rate of 7.5 K/min without holding at or above 1000oC. It was shown that for a slower heating rate a higher sintered density and lower swelling was obtained. https://lup.lub.lu.se/student-papers/record/4358081/file/4358082.pdf application/pdf 9805084 yes 2014 eng Technology and Engineering ISRN LUTFD2/TFMT --14/5044--SE 4358081 2014-03-11T14:31:07+01:00 2016-01-26T14:47:47+01:00 2016-01-26T14:47:47+01:00

The purpose of this master thesis is to investigate thermal properties of concrete so additional costs and negative environmental impacts can be minimized. Measurements of thermal properties of different Swedish aggregates from existing quarries were investigated. It will also study if the thermal properties affect ther thermal expansion of concrete. The experimental study in this work was done in laboratory conditions. Preparation studies that were made before casting concrete were sieving aggregates, density of aggregates and moisture content. While the concrete was fresh standard tests such as slump, air-content and density of fresh concrete were made. When the concrete was 28 days old compressive cube strength and thermal expansion measurement were executed. The thermal properties (thermal conductivity, volumetric heat capacity and thermal diffusivity) were measured on aggregates and concrete cubes with the instrument Hot Disk 2500-S.<br /> <br /> The results show that the minerals quartz and magnetite have significantly different thermal properties than the other studied aggregates/concretes. The aggregate/concrete with high amount quartz mineral has high thermal conductivity and diffusivity. The aggregates/concrete with magnetite has high thermal conductivity and volumetric heat capacity. The other aggregates and concretes have similar thermal properties. The thermal expansion coefficients have similar values (12.6-15.5∙ 1 /⁰C) for different aggregates, and it was not possible to see if there was a correlation between them and the thermal properties. Thus was the value of thermal expansion coefficient in a range that is normal for concrete. The thermal shock resistance is dependent of the thermal conductivity, thermal expansion coefficient, fracture strength and elastic modulus. The concretes with high thermal conductivity also had high thermal shock resistance whereas so such concrete should better resist rapid temperature changes.<br /> <br /> The conclusions that can be drawn from this work are that the thermal properties of the aggregates will be reflected in the properties of the concrete. For both thermal conductivity and heat capacity the values for the dry concretes (RH 10-30%) were about 40-70% of the values of the aggregates. Note that this conclusion only applies for thermal conductivity and heat capacity and does not apply on thermal diffusivity, since diffusivity is the ratio of conductivity and capacity it will be similar in the concrete. In this study only two aggregates significantly affected the thermal properties: quartz has high thermal conductivity and diffusivity and magnetite rock has high thermal conductivity and heat capacity. Another conclusion from this study was high thermal conductivity also give high thermal shock resistance, where the concrete resist rapid temperature changes better. https://lup.lub.lu.se/student-papers/record/4358448/file/4358449.pdf application/pdf 3531334 no 2014 eng aggregates thermal properties Concrete heat capacity thermal conductivity thermal expansion coefficient thermal shock resistance. high thermal mass buildings thermal diffusivity Technology and Engineering 0348-7911 TVBM-5095 5095 4358448 2014-03-11T18:14:38+01:00 2014-03-12T17:51:57+01:00 2014-03-12T17:51:57+01:00

They are implemented in a popular high-level programming language to compare their performance on a set of real instances. We also explore ways to parallelize each of the algorithms and discuss what benefits and detriments those implementations hold. https://lup.lub.lu.se/student-papers/record/4359826/file/4359849.pdf application/pdf 897795 no 2014 eng edge coloring graph algorithm cubic graph performance test performance comparison Technology and Engineering https://lup.lub.lu.se/student-papers/record/4359826/file/4359862.zip application/zip no 4359826 2014-03-17T11:52:15+01:00 2014-09-04T08:29:47+02:00 2014-03-17T12:44:31+01:00

The hexacopter used is a ArduCopter 3DR Hexa B and the work follows a model-based approach using Matlab Simulink, running the model on a PandaBoard ES after automatic code generation. The main challenge will be to investigate how data from an Internal Measurement Unit can be used to aid an already implemented computer vision algorithm in a GPS-denied environment.<br /> <br /> First a physical representation is created by Newton-Euler formalism to be used as a base when developing algorithms for estimation and control. To estimate the position and velocity of the hexacopter, an unscented Kalman filter is implemented for sensor fusion. Sensor fusion is the combining of data from different sensors to receive better results than if the sensors would have been used individually. Control strategies for vertical and horizontal movement are developed using cascaded PID control. These high level controllers feed the ArduCopter with setpoints for low level control of angular orientation and throttle.<br /> <br /> To test the algorithms in a safe way a simulation model is used where the real system is replaced by blocks containing a mix of differential equations and transfer functions from system identification. When a satisfying behavior in simulation is achieved, tests on the real system are performed.<br /> <br /> The result of the improvements made on estimation and control is a more stable flight performance with less drift in both simulation and on the real system. The hexacopter can now hold position for over a minute with low drift. Air turbulence, sensor and computer vision imperfections as well as the absence of a hard realtime system degrades the position estimation and causes drift if movement speed is anything but very slow. https://lup.lub.lu.se/student-papers/record/4359940/file/4359943.pdf application/pdf 984617 no 2013 eng Technology and Engineering ISRN LUTFD2/TFRT--5930--SE https://lup.lub.lu.se/student-papers/record/4359940/file/4359945.pdf application/pdf no 4359940 2014-03-17T14:42:38+01:00 2014-03-30T14:21:01+02:00 2014-03-30T14:21:01+02:00

Interviews conducted with active parties in the industry shows that the current guidelines for using the ALARP-principle results in a variation of the methods used to decide whether a risk can be considered reduced to ALARP. Furthermore several respondents are of the opinion that the application of ALARP in risk analyses is not performed correctly. Suggestions for reducing these problems include more detailed regulation and guidelines regarding the use of ALARP in land-use planning, in combination with better data selection in calculations of risk levels. https://lup.lub.lu.se/student-papers/record/4360292/file/4360300.pdf application/pdf 1087558 no 2014 swe ALARP fysisk planering riskanalys tillämpning land-use planning risk analysis real-world application Technology and Engineering 1402-3504 5451 4360292 2014-03-18T13:16:00+01:00 2014-03-18T13:22:40+01:00 2014-03-18T13:22:40+01:00

This trend has also become a part of the medical rotary industry. As a part of a SMS, Flight Safety Training (FST) is included, which consist of Human factors, Crew Resource Management (CRM) -training and the creation/shaping of attitudes and safety culture. During 2012 a SMS was implemented in Scandinavian MediCopter Ab. This study attempts to discover if the implementation of the FST tool in the SMS has an effect on how professional aviators speak about safety and how the training curriculum is affected. <br /> <br /> For the qualitative research nine professional pilots and flight instructors working with FST and duty in a Helicopter Emergency Medical Service (HEMS)-organization were interviewed about how they perceive the language and syllabus change during the last five years. Additionally the training curriculum was reviewed both before and after the implementation of the SMS. The results imply that language change is difficult to connect to implementing a SMS alone. The change can arguably be seen as being intertwined with deeper phenomena and is a result of a broader change, which does come incrementally. The study hints that as a part of such a change, the SMS helps people to have a more open and transparent approach to safety and increased incident/accident reporting. Changes in the curriculum could be found, which in part are also connected to other aspects, like authority and customer requirements. Additionally the results suggest that the SMS can contribute in making FST and reporting actually feel less bureaucratic, which is a phenomenon usually attributed to SMS. https://lup.lub.lu.se/student-papers/record/4361489/file/4361508.pdf application/pdf 481265 no 2014 eng FLMU05 Technology and Engineering 4361489 2014-03-20T16:16:38+01:00 2014-09-05T08:44:10+02:00 2014-03-21T07:55:08+01:00

This type of organization often presents challenges when it comes to control and management. Arriva DK suffers from high order costs due to lack of coordination between the depots and the suppliers. To address these issues Arriva wants to introduce a central warehouse.<br /> Purpose<br /> The aim of the thesis is to optimize inventory management by creating simulation models that from a cost perspective explore the effects of introducing a central warehouse for spare parts.<br /> To provide Arriva DK with simulation models of the supply chain and inventory management, both with – and without a central warehouse.<br /> Method<br /> The thesis is built on Hillier and Lieberman’s Operations research method. Data used in the thesis consist of both primary and secondary quantitative and qualitative data. Literature studies have also been done and are the basis for the theory. Two simulation models were built. The first model represents an optimized decentralized situation that uses joint replenishment. The second model represents a system with a central warehouse, which also uses joint replenishment. Thereafter the models were compared to determine if an investment in a centralized system is profitable.<br /> <br /> Conclusions<br /> The results from the simulation study showed that the total cost for the CW-model is higher than the DC-model in all scenarios. Both the holding- and order cost will be higher with a central warehouse.<br /> The major advantage of using a central warehouse is that the number of orders to the suppliers will be reduced by more than 50%. This along with the suppliers only have to deliver to one location will result in price reductions on the products. Even with small discounts, will a central warehouse be profitable since the procurement cost represents such a large part of the total cost. https://lup.lub.lu.se/student-papers/record/4362211/file/4362215.pdf application/pdf 2043124 no 2014 eng Central Warehouse Joint replenishment Multi-echelon Simulation Technology and Engineering 14/5482 4362211 2014-03-24T15:22:36+01:00 2014-03-24T15:33:24+01:00 2014-03-24T15:33:24+01:00

The technology can be used to identify individual particles in order to sort wanted material from unwanted material. Today, the technology is widely used in different industries such as the food industry, the recycling industry, and to some extent the mining and mineral processing industry. If fully implemented in the mining and mineral processing industry several critical areas, such as energy/water consumption and mineral reserves, can be improved.<br /> The sensor-based sorting technology is thoroughly presented in this report, together with information about benefits, costs and limitations. A case study has also been conducted, where the technology was analyzed at a specific mine site in Austria. The result of this study was that the technology can help increase the annual revenue, extend the life time of the mine, and lower the environmental impact.<br /> An attempt was also made to define the actual market potential of the technology. The conclusion was that the market potential is high, however the potential has not been fully utilized.<br /> Since the technology is able to deliver an increased value, and most technical limitations seem possible to overcome, the near future of the technology in the mining and mineral processing industry is expected to depend on non-technical aspects. Such aspects contain both psychological factors that affect the customer behavior, and manufacturers’ attitude to product development. https://lup.lub.lu.se/student-papers/record/4362219/file/4362220.pdf application/pdf 1193751 yes 2014 eng Sorting Sensor-based sorting Sorting technology Mining Minerals Sensor-based Wolfram Scheelite Mittersill Technology and Engineering 14/5483 4362219 2014-03-24T15:28:10+01:00 2014-03-24T15:33:13+01:00 2014-03-24T15:33:13+01:00

A booster cushion is a cushion used for children age 4-12 years and the purpose of the cushion is to relocate the child into an elevated seat position. A market analysis was made to ensure the new concept met the requirements of Läreda Mekan and end costumers. The analysis consisted of interviews with Läreda Mekan, car salesmen and end costumers. The collected data from the interviews was needed to establish the customer and company needs. A wide range of different concepts were then developed. Many of the concepts were removed as they did not follow the customer and company requirements. The concepts which passed the screening process were incorporated with each other to create dynamic 3D-models in CAD. The most suitable CAD-model was then chosen and built as a prototype. The construction of the prototype was executed in the workshop at Ingvar Kamprad Design Centre, LTH. Machines that were used to build the prototype were a water jet cutting machine, bending machine and spot welding equipment. The final concept consisted mainly of new parts but also of already existing parts manufactured by Läreda Mekan. The already existing parts were used to adjust the cushion from the base position to the first height position and the new parts were used as an extension moving the cushion to a second height position. The result of the project was a working prototype which showed how a future integrated booster cushion vertically adjustable in two steps could work. https://lup.lub.lu.se/student-papers/record/4362440/file/4362441.pdf application/pdf 12776096 2015-03-25 no 2014 swe Integrated booster seat integrated booster cushion child safety child seat prototype product development two steps Technology and Engineering ISRN LUTMDN/TMKT 14/5489 SE ISRN LUTMDN/TMKT 14/5489 SE 4362440 2014-03-25T12:09:19+01:00 2015-03-25T03:57:04+01:00 2014-03-25T13:36:48+01:00

We react in certain ways when exposed to certain information but considering those reactions stem from experiments mainly conducted on Americans is not something that is considered to be of importance. Whereas these statements tend to hold true for many aspects, lately some studies executed on people from different countries with very different cultural background have investigated if those psychological rules indeed are applying on every individual being (Henrich, Heine, &amp; Norenzayan, 2010).<br /> <br /> When it comes to how Westerners and Easterners (especially Americans and Chinese) process information, remarkably enough plenty of differences were discovered. This thesis will discuss those differences and attempt to analyse whether or not those inequalities could be used to understand how we may adjust technical products when it comes to designing products, mainly focusing on interaction design and user experience.<br /> <br /> It was found that there may be several relations to cultural background and that they might affect preference towards user interfaces. Even though the amount of participants lacked in some user groups, and more test subjects would be needed, some noticeable patterns were still discovered. It seems like a preference towards more interactivity and more complex and colourful design may be more appreciated by the typical Chinese user, while it seems like it’s basically the opposite for the typical western user. https://lup.lub.lu.se/student-papers/record/4389289/file/4389303.pdf application/pdf 4521545 no 2013 eng creativity copycat culture field-dependence holism reductionism Technology and Engineering 4389289 2014-04-03T13:26:58+02:00 2014-04-09T14:31:01+02:00 2014-04-09T14:31:01+02:00

Inadequate insulin secretion prevents efficient glucose metabolism and is a serious health risk. Major available treatment modes are multiple daily<br /> injections of insulin and insulin pump therapy providing continuous subcutaneous infusion.General insulin regimens for low- and high-fat meals were studied in silico to improve current pump therapy for type 1 diabetes. This involved modifications of the FDA-accepted UVA/Padova metabolic simulation model for evaluations of meals with different absorption rates. Simulations of meals with varied fat content under this modified model demonstrated qualitative replications of published data. Subsequently, an insulin regimen library with<br /> optimized regimens under open- and closed-loop settings for a variety of meal compositions was constructed using the particle swarm optimization algorithm.<br /> Calculations show that the optimal open-loop insulin delivery profiles for low-fat meals comprise a normal bolus or short square wave depending on the size of the meal. The preferred delivery pattern for large meals is a short insulin wave due to the increased risk for<br /> hypoglycemia. Interestingly, the optimal open-loop regimens for high-fat meals are typically biphasic, but can extend to multiple phases for large slow absorbing meals. Furthermore, individual in silico optimizations revealed that patients with high insulin sensitivity could benefit from biphasic insulin deliveries when consuming high-fat meals. Preliminary investigations of the optimal closed-loop regimens under varied fat content also display bi- or triphasic patterns for high-fat meals and are primarily influenced by the carbohydrate content in the meal.<br /> The novel insulin delivery profiles identified in this work comprise new and unique waveforms that provide better control of postprandial glucose excursions than existing schemes. Furthermore, the novel regimens are also more or similarly robust to uncertainties in various<br /> parameter estimates with the closed-loop schemes displaying superior performance and robustness. The proposed closed-loop strategy does not rely on optimal basal therapy and is therefore a realistic approach that could have real-life applications in an artificial pancreas. https://lup.lub.lu.se/student-papers/record/4389464/file/4389465.pdf application/pdf 1195964 no 2013 eng type 1 diabetes insulin pump therapy insulin dosage artificial pancreas particle swarm optimization biomedical control Technology and Engineering ISRN LUTFD2/TFRT--5928--SE https://lup.lub.lu.se/student-papers/record/4389464/file/4389467.pdf application/pdf no 4389464 2014-04-03T15:33:44+02:00 2014-04-07T10:07:15+02:00 2014-04-07T10:07:15+02:00

The effect of additives in the extinguishing water is fairly unknown. In this report small-scale experiments shows that additives and fire retardants can provide a significant improvement in extinguishing effect on fire with class A fuel. A total of nine additives in water were tested. The extinguishing media was applied to a bonfire of pine studs. The effect was measured as the time it took for the media to reduce the temperature just above the fire to 200 degrees Celsius and a visual observation regarding when no flames was visible. <br /> Depending on which part of the extinguishing process that is studied various products show different effect. Some of the additives gave a good effect in the gas phase of the fire and some were better at surface cooling.

An analysis has been done on two residential buildings by two different developers, a private and the other commercial. The problems that many buildings in Kurdistan have had and still have today are the poor indoor comfort temperature and high energy use; this appears through an analysis carried out on location and interviews with architects, engineers and a questionnaire survey of residents in the city. A simple method to improve indoor climate and reduce energy costs throughout the lifetime of a building is through introduction of insulation. This was demonstrated by the U-value calculations on the different elements of the building with and without insulation. The task also showed that building techniques are in great need to be modernized and streamlined. https://lup.lub.lu.se/student-papers/record/4392157/file/8961712.pdf application/pdf 2447331 no 2014 swe kurdistan sulaymaniyah enfamiljshus analys u-värde förslag till förbättringar Technology and Engineering 4392157 2014-04-09T00:00:00+02:00 2018-10-18T10:28:20+02:00 2014-04-10T00:00:00+02:00

In order to deliver the highly energetic neutrons, protons are accelerated to energies in the GeV range and then collided with a spallation target. This acceleration process requires superconducting cavities cooled down to slightly over 2 K, and this cooling is done through the cryogenic system using helium.<br /> <br /> In this project, the cryogenic system at ESS has been modeled in Dymola. Simulations have been made of the cool-down and warm-up of the superconducting part of the accelerator. This was done in separate simulations for the cryogenic distribution line and for an individual cryomodule. Additionally, a model was created for the helium discharge system, in order to size the vent line leading rapidly expanded<br /> helium from the cold masses back to the cryoplant. The mathematical tools and structure of the modeling are described in a separate chapter. https://lup.lub.lu.se/student-papers/record/4392724/file/4392725.pdf application/pdf 2870337 no 2014 eng Technology and Engineering 0280-5316 ISRN LUTFD2/TFRT--5939--SE https://lup.lub.lu.se/student-papers/record/4392724/file/4392727.pdf application/pdf no 4392724 2014-04-11T11:35:24+02:00 2014-04-28T12:04:47+02:00 2014-04-28T12:04:47+02:00

Southeast of Thuan An<br /> inlet, one of the two inlets of the lagoon, a groin was constructed in 2008 as a measure to reduce the<br /> sediment transport to prevent the inlet from closing. This groin has caused erosion of the eastern sand<br /> spit of the inlet and accretion of sediment on the coastline south east of the groin. The objectives of<br /> this study was to make a model of the sediment transport on the southeast side of the groin to be able<br /> to analyse how different measures to reduce the erosion of the inlet would affect the sediment<br /> transport past the groin.<br /> The field measurements and parts of the data collection took place in Vietnam during nine weeks in<br /> the beginning of 2013. The position of the coastline at Thuan An inlet was measured and the rest of<br /> the data, such as e.g. wave data, bathymetry data, previously measured coastlines and sediment<br /> transport was obtained from Institute of Mechanics in Hanoi. Other data used in this thesis was also<br /> obtained from The University of Agriculture and Forestry in Hue and from The Oceanographic<br /> Institute in Nha Trang. The study area has a tropical monsoon climate with two monsoon season per<br /> year – the southeast monsoon and the northwest monsoon. The micro tidal climate in the area is fully<br /> semi-diurnal and gives that the main sediment transport is wave induced.<br /> The modelling software GENESIS was used to model the sediment transport past the groin. The<br /> model was calibrated and validated using measured data and then the sediment transport on the<br /> southeast side of the groin was modelled during the years 2013 to 2017. First, the case where no<br /> measures were taken was modelled, to see what will happen if no changes of the groin were made.<br /> After that, three different measures to decrease the accretion of sediment on the southeast side of the<br /> groin (i.e. increase the sediment transport past the groin in order to reduce the erosion of the Thuan An<br /> inlet) were modelled and analyzed. These three measures were making the groin shorter, increasing<br /> the permeability of the groin and dredging sand from southeast side of the groin.<br /> The result of the model and the different measures to reduce erosion were discussed. The conclusion<br /> was that interventions to reduce the erosion are needed to protect the lagoon and the people living<br /> around it and making their livelihood from it. Many people work with e.g. fishery, aquaculture and<br /> agriculture and these occupations could be severely affected of the results of continuous erosion, such<br /> as changed water environment in the lagoon and flooding. https://lup.lub.lu.se/student-papers/record/4393060/file/4393063.pdf application/pdf 4678434 no 2014 eng Thuan An Hoa Duan Tam Giang-Cau Hai lagoon system lagoon inlet groin longshore sediment transport Thua Thien-Hue province GENESIS Huong River Technology and Engineering 1101-9824 14/5002 Examiner: Hans Hanson 4393060 2014-04-14T11:30:36+02:00 2019-03-29T14:20:04+01:00 2014-04-14T21:11:13+02:00

The Powerbox is a product for sourcing of compressed air, vacuum suction and electric power. Nederman is a strong brand and considered a market leader in many of its areas. The Powerbox is however regarded as being too expensive and in need of improvements.<br /> The new design should be a long-term solution since these products have long market life cycles. Focus during the process has been to make a product that has improved ergonomics, functionality and cost efficiency.<br /> The thesis has been conducted based on well known product development methods. Primarily has Ulrich and Eppinger’s Product Design and Development been used. [1]<br /> The needs and demands for the new box were collected from interviews and observations at auto workshops and during discussions with experienced people from Nederman. The old Powerbox was also analyzed thoroughly to identify weaknesses, strengths and cost driving factors. Combined with a research of the competitors it gave a good foundation to work from and it was formulated in a function analysis.<br /> After the concept generation phase the process for detail design development of the product begun. During the project it was continuously checked that the different suggestions and concepts were feasible. Materials, manufacturing methods and new features were all subjects that were examined and developed. Several mock-up prototypes were made and a final prototype in full-scale size was made in similar materials as the suggested final design.<br /> The result was a Powerbox with new design, added functionality and reduced cost. The new design of the Powerbox is made up of fewer and cheaper parts than the current product. It has also increased functionality in terms of ergonomics due to the bevelled bottom part. The final cost reduction was estimated to be over 40%, for the examined parts, which was more than the targeted 35%. The new box should give Nederman good possibilities to increase the sales of the product and add value to the customers. https://lup.lub.lu.se/student-papers/record/4393216/file/4393285.pdf application/pdf 24461536 yes 2014 eng Product development workshop equipment redesign Technology and Engineering 4393216 2014-04-14T13:06:34+02:00 2014-05-12T10:56:38+02:00 2014-05-12T10:56:38+02:00

studentPublicationsH3 Johan Larsson author Jan Sternby supervisor Professor Tore Hägglund supervisor Department of Automatic Control v1000253 department When treating patients suffering from renal failure with hemodialysis, an obvious point of interest is the actual blood cleaning efficiency of the dialyzer (artificial kidney). This efficiency is called clearance or dialysance.<br /> The method currently used for estimating clearance is based on doing a step-change on the process. Due to the nature of the process, this method is slow and has a relatively large output spread.<br /> This master thesis investigates a new method of finding clearance by means of system identification. The dialyzer is modelled as a discrete-time system, and perturbed by use of a pseudo-binary random sequence. The input/output-data is then fed into an optimal Kalman filter for parameter estimation. The gain and offset of the identified system is directly related to the dialyzer clearance of the treatment.<br /> The method shows promising results, usually converging to good parameters within 15 minutes, and then tracking changes continuously for the rest of the treatment. It also provides better accuracy, with a considerable reduction in spread compared to the old method. Main obstacles stem from variable time-delays in the system and measurement offsets. https://lup.lub.lu.se/student-papers/record/4394033/file/4394043.pdf application/pdf 8117661 no 2014 eng System identification pseudo-random binary sequence PRBS Kalman filter hemodialysis dialyzer modelling Technology and Engineering 0280-5316 ISRN LUTFD2/TFRT--5934--SE https://lup.lub.lu.se/student-papers/record/4394033/file/4394045.pdf application/pdf no 4394033 2014-04-17T09:37:38+02:00 2014-04-28T11:53:54+02:00 2014-04-28T11:53:54+02:00

This was done with the ultimate goal of producing a hard<br /> magnetic ferrite powder for powder metallurgical production of permanent magnets. For this study, eight<br /> different compositions of iron, cobalt and boron were atomized using atomization by water and a gas-water<br /> combination atomization (GA/W). The atomization type was found to have a limited impact on the particle<br /> morphology and GA/W atomization also showed a slight reduction in the oxygen contents.<br /> <br /> X-Ray Diffraction (XRD) was used to characterize the phase composition in conjuncture with Simultaneous<br /> Thermal Analysis (STA) and dilatometry to find the temperature of any phase transitions. One of the alloys was<br /> also analyzed using XRD, STA and Light Optical Microscopy (LOM) at different stages of milling and heat<br /> treatment under different atmospheres so as to determine the best way to treat the powder for crystal growth.<br /> <br /> Representatives from all eight alloys was analyzed in a Vibrating Sample Magnetometer (VSM) to produce<br /> hysteresis loops and determine the magnetic characteristics. In these analyses the composition, heat treatment<br /> and milling was varied in an attempt to discover any dependencies. Two samples that were heat treated for this<br /> purpose, were also coated with SiO2 using tetra-ethyl-orto-silicate (TEOS) in an attempt to hinder sintering<br /> normally accompanied with long heat treatments.<br /> <br /> A SEM analysis indicated that the grain growth is a slow process but was unable to quantify a growth rate due to<br /> a large variance. The equivalent LOM analysis was inconclusive but suggested an estimation of the grain size.<br /> These analyses were also used to estimate the number of grains per particle but vary heavily between 10 and<br /> 1&#39;000&#39;000.<br /> <br /> All but two of the alloys were, with their stoichiometric composition, found to contain &gt;80% Fe2B with the<br /> remainder being FeB. Trace amounts of other phases could exist but was not possible to resolve in the XRD<br /> analyses. The remaining two alloys, having a non-stoichiometric composition, were found to contain mostly<br /> (Fe,Co)3B2 (&gt;50%) with the remainder being FeCo. Thus it&#39;s concluded that the stoichiometric composition is<br /> more beneficial to the project.<br /> <br /> Heat treatment of these materials was beneficial in the transformation of (Fe,Co)B into (Fe,Co)2B regardless if<br /> the atmosphere is N2 or H2.<br /> <br /> A phase transition between an (Fe,Co)2B type phase and another phase has been detected around 550OC using<br /> DSC. This is confirmed by phase diagram comparison, reference measurement of pure Fe in DSC and is<br /> consistent with DSC of etched samples.<br /> <br /> The best hard magnetic properties has been found to be in the least heat treated and least milled G336 sample.<br /> Heat treatments and milling both, consistently, showed a deleterious effect on the hard magnetic properties. The<br /> heat treatment having this effect remains unexplained but the milling introduced defect in the material that could<br /> have acted as nucleation points for magnetic sub-domains.<br /> <br /> The SiO2 coating worked well as a coating to prevent sintering but had a deleterious effect on the magnetic<br /> properties of the material. The reasons for this are discussed.<br /> <br /> Some of the alloys were found to contain a large fraction of particles containing bubbles, mainly from the water<br /> atomizing process. These have not been seen to have any effect on the magnetic properties. https://lup.lub.lu.se/student-papers/record/4407394/file/4407397.pdf application/pdf 17741898 no 2014 eng Crystalline metals Magnetic materials Hard magnetic materials Electro-magnetic applications Single crystalline powder Powder metallurgy Fe2B FeB Water atomization Gas/Water atomization non-RE hard magnetic material.

The standard specifies, among other things, API, aggregation and data model.<br /> The implementation is not fully compliant, as the time-frames of the thesis did not allow for such an endeavour. However, a partial implementation turned out to be possible. For example does the standard impose functionality for navigation between different course modules, called SCO:s.

However, there is often an uncertainty in how much margin there is in the path plan and if they are trustworthy. The goal of this report is to determine the margin in pre-programmed path plans, using the program AutoTurn, for trucks with a length of 10 meters. This report discusses drive and rest times how both the drive and rest times depend on the drive time of different paths to reverse in to goods receptions. A time study has been performed and a path plan study as well as interviews to obtain a sufficient amount of data. The time study was conducted at two supermarkets in Sweden during February 2014. These supermarkets were chosen after inventorying industry plots, bigger and smaller stores, supermarkets and malls with a goods reception. One criterion was that the goods reception had to be enclosed by a fence and there should also be many deliveries every day to get a sufficient amount of data. 80 trucks where studied, and the time it took to reverse and the time the trucks spent on the area were recorded. The results of the time study were used to choose the three paths to include in the path study. The three path plans were tested in AutoTurn and were measured. Then a field study was conducted for two days in the beginning of March 2014, and three path plans were tested with a truck of the type Scania Highline and with a length of 10 meters. The results from the time study show that the majority of the trucks reverse to the goods reception in 30-39 seconds. The time of reversing varies between 20 to over 60 seconds. At the two different goods receptions, the time the trucks spent in the area varies between four minutes and up to 60 minutes. The results from the path study show that the path plans are not the same in reality as in the program. The path plans in AutoTurn is more generous with margins and takes more space than a 10 meter truck does in reality. The conclusion is that trucks with a length of 8-12 meters with unloading that contains unboxing inside the markets drive and rest times are not affected by the time of reversing can be made from the interviews and the survey. As only two goods receptions and 80 trucks were studied, it is not possible to make any general conclusion of how the reversing time affects the drivers’ drive and rest times. There are margins in AutoTurn when a truck drives forward to the right with full steering angel. The margins are between 0,73 m to 3,90 m.

During veldfires, the relationship between the fire actors and the affected population is important to the crisis communication. In the Dr. Kenneth Kaunda District Municipality there are primarily three fire actors: the fire brigade, the Fire Protection Association (FPA) and Working on Fire (WoF). The aim of the study is to explore the communication between the different stakeholders during veldfires. Semi-structured interviews were performed with fire actors and farmers. The interviews were transcribed, coded and categorized according to the research questions. The results indicate that the communication performed by the FPA adheres to the needs of the<br /> affected population while the communication performed by fire brigade does not meet the needs. The communication within the FPA is believed to be successful due to the fact that it is performed as dialogical<br /> two-way communication. The communication between the different stakeholders is affected negatively by the stakeholders’ preferences of communicating in different languages. Already established networks,<br /> such as the one created by the FPA, have proven to be highly beneficial when veldfires occur. The study focuses on the Dr. Kenneth Kaunda District Municipality but the results may be beneficial to stakeholders<br /> in other locations as well. https://lup.lub.lu.se/student-papers/record/4434797/file/4434800.pdf application/pdf 706817 no 2014 eng Crisis communication Veldfires Language Networks Trust Credibility Dr. Kenneth Kaunda District Municipality South Africa Kriskommunikation Markbränder Språk Nätverk Förtroende Trovärdighet Dr. Kenneth Kaunda District Municipality Sydafrika Technology and Engineering 1402-3504 5397 4434797 2014-05-06T13:09:02+02:00 2020-12-03T14:26:08+01:00 2014-05-06T13:17:17+02:00

Limited to highway scenarios, a method combining data from different sensors to extract information about the currently associated lane is presented.<br /> <br /> The suggested method splits the problem in two main parts, lane change identification and road edge detection. The lane change identification mainly uses information from the camera to model the lateral movement on the road and identifies the lane changes as a relative position on the road. This part is implemented with a particle filter. The road edge detection enters radar detections to an iterated Kalman filter and estimates the distances to the road edges.<br /> <br /> Finally, a combination of the filter outputs makes it possible to compute an absolute position on the road. Comparing the relative and absolute positioning then leads to the desired lane association estimate.<br /> <br /> The results produced are reliable and encourages to continue approaching this problem in a similar manner, but the current implementation is computationally heavy. https://lup.lub.lu.se/student-papers/record/4436923/file/4436924.pdf application/pdf 2400109 no 2014 eng Technology and Engineering ISRN LUTFD2/TFRT--5937--SE 4436923 2014-05-09T16:35:29+02:00 2014-05-12T11:58:39+02:00 2014-05-12T11:58:39+02:00

The project was performed at MarineDiesel, a company producing diesel engines for marine applications in Ängelholm, Sweden. A need of a sterndrive strong enough for large diesel engines is present on the market. This thesis involves hydraulic systems and mechanical geometry for trimming and steering of the sterndrive and was part of the initial development of a prototype drive. The intention has been to reach a prototype level of design for the hydraulic cylinders and choosing an appropriate trim pump unit. The project has however been postponed leaving critical decisions untaken. This made it more convenient to perform the thesis as a parametrical study shaped to ensure the work carried out could come to as much use as possible. A concurrent analysis was made to get a wide perspective of existing concepts and detail solutions in order to inspire ideas for concept generation. Eleven realistic concepts divided into two sections were found and evaluated by concept scoring according to Product design and development, Karl T. Ulrich and Steven D. Eppinger [1]. The main focus was on robustness redundancy and safety. Based on the concept scoring seven concepts were rejected and the rest examined further. A calculation chart was conducted to evaluate the forces in the system and to provide output parameters for future prototyping. The chart, together with a second scoring procedure, motivated the conclusion to use the combination of two concepts, traditional gimbal configuration with dual external steering and trimming cylinders. To widen the steering range an idea of using a universal joint attached to the steering cylinder waist was found, making the total width of the drive significantly narrower. The result of the thesis is a choice of concept and a calculation chart providing the conceivable parameters dimensioning the system when crucial decisions are made in future development. https://lup.lub.lu.se/student-papers/record/4437473/file/4438132.pdf application/pdf 3171132 LU/LTH access 2014 eng Sterndrive trim/tilt steering cylinder gimbal Technology and Engineering 4437473 2014-05-13T12:54:06+02:00 2014-05-16T10:44:18+02:00 2014-05-13T13:36:28+02:00

The aim of this work is to provide feedback as well as showing if the revised building regulations have achieved some of the major purposes and objectives that were the basis for the revisions. The survey method was chosen as the evaluation tool in order to provide a qualitative analysis from a user perspective. The total number of respondents that participated in the surveys were 155 in Sweden and 89 in New Zealand, out of which the majority were fire safety consultants. The<br /> results indicate that the revision of the Swedish fire safety building regulations BBR Chapter 5 was a success and that further development should follow the same path. The results further indicated that the revision of the New Zealand fire safety building regulations NZBC Clause<br /> C could not be described as a success, and that a different route may need to be considered for further work and development. Furthermore the surveys pointed to the need for additional guidance for assessment of existing as well as complex buildings in both Sweden and New Zealand. https://lup.lub.lu.se/student-papers/record/4437805/file/4437806.pdf application/pdf 6874019 no 2014 eng Building regulations fire safety Sweden New Zealand BBR NZBC survey Technology and Engineering 1402-3504 5463 4437805 2014-05-14T12:56:25+02:00 2014-05-14T13:02:00+02:00 2014-05-14T13:02:00+02:00

In this thesis, I examine polymer materials for acoustofluidic applications, and find several functioning, and promising, materials and designs.<br /> <br /> Microfluidics involves manipulating small volumes of fluids for novel applications, and acoustofluidics describes the application of ultrasound to microfluidics. This technique puts certain restraints on the choice of materials. In acoustofluidics, the material is an integral part of the function of the device, and since the field’s inception the material of choice has mainly been hard materials like silicon and glass. Their use is accompanied by high costs and complicated processes. Polymers do not generally possess the same acoustic properties as these harder materials. Therefore polymers need to be tested, and optimized, to work effectively.<br /> <br /> In this thesis I decided to investigate a few specific polymers and designs of acoustofluidic devices in order to evaluate their viability and performance. Hopefully, my insights can be generalized to other polymers as well. I designed, fabricated, and tested, chips made from three different materials: cyclic olefin copolymer (COP), poly(methyl methacrylate) (PMMA), and polystyrene (PS). All chips were designed with wavelength-matched air channels on both sides of a straight fluid channel.<br /> <br /> I found that all three polymers could successfully be applied in the construction of acoustofluidic devices. I observed acoustic focusing in all chips that were made without physical defects, with varying success and efficiency depending on material and design. Chips of COP, PMMA, and PS showed concentrated central focusing of polystyrene particles at low flow speeds (5-25 μl/min) from a resonance between air channels. Several problems persist and remain to be solved before polymers can replace traditional materials, problems such as fabrication, design, optimization, and heating of the chip.<br /> <br /> These findings prove that it is possible to use polymers in a range of acoustofluidic applications. Their use can accelerate research and enable cheaper commercial devices. https://lup.lub.lu.se/student-papers/record/4438156/file/4438163.pdf application/pdf 4198233 LU/LTH access 2014 eng Technology and Engineering https://lup.lub.lu.se/student-papers/record/4438156/file/4438165.pdf application/pdf no 2014-01 4438156 2014-05-16T11:18:58+02:00 2015-10-08T09:52:14+02:00 2014-05-16T11:40:38+02:00

The building code, EKS 9, gives some restrictions and methods to determine this and one of these methods is the local fire (Swedish standards institute (1), 2007) which is evaluated and analyzed in this master thesis. The aim with this master thesis is to identify difficulties with the method and to determine which parameters of both fire and construction are central for the design of fire protection and also to<br /> evaluate the parameters of the local fire for which the design method is most sensitive to. A further goal is to develop a guide for the local fire design method and to perform a case study to apply the developed guidance for a certain type of hall building. It is especially the distance between the local fire and the construction that is important to be aware of when the local fire design method should be used. Other parameters like diameter and heat release rate per unit area are also important to keep in mind when conducting the method. https://lup.lub.lu.se/student-papers/record/4438248/file/4438252.pdf application/pdf 2516300 no 2014 swe steel constructions regression analysis fire design of building structures critical resistance cargo load factor heat release rate dimensionerande lokal brand dimensioneringsmetod Br2-Hallbyggnad EKS 9 Eurokod brandens parametrar ståltemperatur stålkonstruktioner regressionsanalys brandteknisk dimensionering av bärverk kritisk bärförmåga lastutnyttjandegrad effektutveckling Technology and Engineering 1402-3504 5437 4438248 2014-05-16T13:19:02+02:00 2020-12-03T14:26:08+01:00 2014-05-16T13:28:16+02:00

The building is used for a variety of sports and activities on an everyday basis. On occasion the building is also used for larger events such as sports competitions, dinner parties, nightclub events and for lodging. This poses new challenges to the current fire protection systems of the building and therefore a deterministic evaluation has been performed to investigate occupant safety in case of a fire.<br /> <br /> A risk analysis has been performed to determine the worst credible fire scenarios when taking into account likeliness and consequence. This identifies the buildings karatehall, A-hall and B-hall as locations where an unsafe egress environment is expected. Computer software, calculations as well as qualitative reasoning has been used to quantify available time of egress and time needed for evacuation.<br /> <br /> Based on comparison of these results it was possible to conclude that safe egress cannot be guaranteed for all the scenarios.

Cirkus is a heritage listed building that offers a lot of different events, such as concerts and conferences. This report is limited to only cover the public areas of the building. No account is taken to either economic losses or environmental impacts in case of fire. The method employed is a deterministic scenario analysis that handles uncertainties with a credible worst case approach. From the risk identification three scenarios were selected for further analysis.<br /> <br /> By using different simulation programs the times to critical conditions and evacuation are determined for each scenario. These times were compared to each other and if a negative time margin was obtained the personal safety cannot be ensured. For all three scenarios it was found that measures must be taken and requirements are presented and verified. The requirements are considered not to affect the buildings appearance and this because of the heritage label of the building. https://lup.lub.lu.se/student-papers/record/4448962/file/4448980.pdf application/pdf 4843899 no 2014 swe Brandteknisk riskvärdering BTR Cirkus Stockholm personsäkerhet kritiska förhållanden känslighetsanalys riskanalys Simulex FDS CFAST PyroSim Technology and Engineering 4448962 2014-05-23T12:15:10+02:00 2014-06-10T09:46:06+02:00 2014-06-10T09:46:06+02:00

The report was written by students at the Fire Protection Engineering program at Lund University. The project focuses on the public safety within the building and not on the damage of the property. The building includes different types of activities such as theatre, public library and art museum. The aim was to evaluate the existing fire protection system and find the weaknesses in the system. Initially a visit was made at the object to gather information and get an overview of the building. Risk identification was then carried out to identify the worst case scenarios considering the public safety in the building. Comparisons between time to critical conditions caused by a fire and the time to evacuation were made to see if the fire safety is satisfactory. The areas regarding the two theaters was of most concern and the ones were most improvements were needed. Examples of improvements are education, information and fire safety equipment. The fire safety routines among the staff were estimated to be good according to the visit at Borås Kulturhus. https://lup.lub.lu.se/student-papers/record/4449001/file/4450191.pdf application/pdf 5887485 no 2014 swe BTR Brandteknisk riskvärdering Borås Kulturhus utrymning Simulex CFAST FDS kritiska förhållanden riskanalys känslighetsanalys Technology and Engineering 4449001 2014-05-23T13:17:15+02:00 2014-06-10T09:46:18+02:00 2014-06-10T09:46:18+02:00

Brunnsgården consists of apartments for elderly people with dementia as well as assisted living in serviced apartments. Furthermore the building consists of a section with offices for the staff. This work is limited to a dementia section and a service section where all floors are identical. Moreover it is the residents&#39; personal safety which is mainly considered in the report, as they are not expected to evacuate unassisted in the event of a fire.<br /> Probable fire and evacuation scenarios were designed and based on these, simulations were made in the programs ERM, CFAST and FDS. The time to critical conditions in CFAST and FDS were compared with the time for evacuation from the evacuation scenarios in ERM. More so the results in the simulations were validated through performing sensitivity analysis. The fire safety is deemed to be not acceptable if critical conditions are achieved before everyone has evacuated.<br /> This fire risk evaluation indicates a result in which the fire safety and the ability of evacuation of Brunnsgården nursing home is inadequate and in regard to that an acceptable personal safety is not achieved. The reason why personal safety is not achieved is mainly due to the production and distribution of smoke.<br /> Since the fire safety is insufficient, measures are needed to improve this with the intention of reaching an acceptable level. Suggestion of measures are discussed and listed in the report as two kinds of measures; those that shall be implemented and those that should be implemented. One of the most significant measure, to prevent that critical conditions arise, is that the staff of Brunnsgården nursing home develop a well working fire prevention plan with clear directions of what to do in case of fire. https://lup.lub.lu.se/student-papers/record/4449261/file/4449262.pdf application/pdf 2084814 no 2014 swe Brandteknisk riskvärdering Brunnsgårdens äldreboende FDS CFAST ERM personsäkerhet kritiska förhållanden utrymning känslighetsanalys Technology and Engineering 4449261 2014-05-25T09:46:01+02:00 2014-06-10T09:46:01+02:00 2014-06-10T09:46:01+02:00

In spite of being a highly inhomogeneous<br /> and anisotropic material, as an approximation wood may be modelled<br /> as homogeneous and orthotropic. By means of such a material model,<br /> first order linear elastic theory and a fracture mechanics condition on<br /> the strain energy release rate, a formula is derived for the load bearing<br /> capacity with respect to fracturing. The capacity is further simulated<br /> in 2D with FEM both by employing a linear elastic method with node<br /> releasing and by a non-linear method with a cohesive zone. The validity<br /> of the analytical and numerical models are verified by laboratory tests<br /> comprising 21 small wooden members with varying notch size. The<br /> characteristic value of the capacity is determined by the 5th percentile<br /> with 75 % confidence level.

Three different fire scenarios have been studied in three different parts of the library. The design and assumptions made in the fire scenarios and their impact on the results are discussed in the report. The time to egress relative to the time to untenable conditions is unsatisfactory in one part of the building, barnavdelningen. This leads to that the level of safety is considered unacceptable in this part. Included in the report are appropriate measures to be taken to reach an acceptable level of safety.

While they are designed to increase the efficiency in the warehouse, the implementation of them requires the warehouse implementing it to adjust to the new environment it creates. This adaption have proven hard for the people working there, resulting in that the desired efficiency improvements often have taken longer than expected to achieve. A possible solution to this dilemma might be an increased focus on change management before, during and after the implementation. While there is literature, which has examined the general challenges associated with implementing IT systems such as e.g. ERP, few articles cover the specific challenges when implementing a WMS. Meanwhile, there are many methods and models, which claim to work as guidelines for working with change management, but few (if any) have been tailored to situation of a WMS implementation. <br /> <br /> The purpose for this master thesis is to develop a change management methodology for efficient, high quality, WMS implementations.<br /> <br /> Through interviews with project managers at a company who is developing and implementing a WMS, and with people who is working at different levels within the warehouse, from three companies who have recently implemented a new WMS, the main challenges with a WMS implementation have been identified. Thereafter, an evaluation of some selected change management model was performed where one was selected and modified to fit the context of a WMS implementation. <br /> <br /> The evaluation of change management models led to that the ADKAR model, developed by Hiatt (2006), was ultimately selected. The challenges of WMS implementation proved to be quite similar to a general IT implementation and most challenges can be handled through using the ADKAR methodology in its present form. But through appointing roles and responsibility to different people involved in the change process and tie them to specific activities, the authors believe that the developed methodology could be utilized to decrease the time spent from the implementation to that the desired efficiency levels are reached. https://lup.lub.lu.se/student-papers/record/4450740/file/4450745.pdf application/pdf 1621391 no 2014 eng Change management Warehouse Management System WMS implementation warehouse management challenges in WMS implementations change management methodology change management model ADKAR Technology and Engineering Business and Economics 1651-0100 276 4450740 2014-05-27T08:38:10+02:00 2015-08-12T11:18:13+02:00 2015-08-12T11:18:13+02:00

All three characteristics together make the concept well suitable for a wearable computing device since it takes the user’s interaction and communication behavior to a new level. https://lup.lub.lu.se/student-papers/record/4451017/file/4451023.pdf application/pdf 1558225 no 2014 eng Wearable Computing implicit Human-Computer Interaction Participatory Design Communication behaviors Generation Z Technology and Engineering 4451017 2014-05-27T14:00:44+02:00 2015-06-04T09:35:57+02:00 2014-08-26T16:22:25+02:00

Project Office Manager, PC CHE, Alfa Laval<br /> <br /> Bakgrund: I dagens ökande konkurrenssituation behöver företag erbjuda produkter som marknaden efterfrågar och som samtidigt tar till vara på företagets interna kapabiliteter och resurser. Detta har lett till att det blir allt mer aktuellt för företag att skapa arbetssätt och metoder för hur och vad företaget ska erbjuda för produkter till sina kunder idag och i framtiden, vilket är essentiella byggstenar i området portföljhantering. Området innefattar bland annat komplext beslutsfattande, strategisk koppling, organisering, prioriteringar och utvärdering. Portföljhantering karaktäriseras av osäkerhet och föränderlig information, multipla mål, strategiska överväganden och beroenden mellan produkter, beslutsfattare och platser.<br /> <br /> Syfte: Syftet med uppsatsen är att skapa ett ramverk som företag kan använda för att förbättra sin portföljhantering.<br /> <br /> Metod: Studiens metod grundar sig i en abduktiv ansats. Ett teoretiskt ramverk har skapats utifrån befintlig teori och samtal med anställda på Alfa Laval. Empirin från fallföretaget har både varit av kvalitativ och kvantitativ karaktär som tillsammans med det teoretiska ramverket analyserats för att svara på studiens syfte.<br /> <br /> Slutsatser: Sex områden och deras samberoenden som är viktiga för portföljhantering har identifierats. Dessa områden har resulterat i ett ramverk som beskriver områdena och samberoendet mellan dem. Dessa områden är övergripande portföljstrategi, portföljstrategier för respektive affärsenhet, datainsamling, prioriteringar, genomförande av projekt samt utvärdering och agerande. Sammanfattningsvis behövs det övergripande processer och strategier för att arbetet ska kunna bli enhetligt genom hela organisationen.<br /> <br /> Nyckelord: Portföljhantering, strategi, process, produktportfölj, beslut, datainsamling https://lup.lub.lu.se/student-papers/record/4452051/file/4452053.pdf application/pdf 1768964 no 2014 swe Portföljhantering strategi process produktportfölj beslut datainsamling Technology and Engineering Business and Economics 4452051 2014-05-30T12:55:44+02:00 2015-08-19T11:13:52+02:00 2015-08-19T11:13:52+02:00

The purpose of the report is to evaluate human safety of visitors in case of fire at the racetrack Halmstadtravet and suggest possible solutions if the human safety is deemed insufficient. The purpose is also to train the students in their engineering capability.<br /> <br /> The method is to choose several fire scenarios that challenge the existing fire protection features of the building. The fire scenarios are ranked by likelihood and consequence. The most severe scenarios are simulated in FDS where the time to critical conditions is obtained. The results are compared to evacuation simulations executed in SIMULEX. If safe evacuation is not achieved within the allowed timeframe, an assessment will be carried out to suggest improvements. To examine how robust the solutions are, sensitivity analyses are carried out.<br /> <br /> The assessed building includes a restaurant, kitchen, bleachers and cafés. The existing fire protection features of the building are presented and a comparison is made with Swedish regulations, BBR 20.<br /> <br /> The results of the report shows that safe evacuation is not achieved within the allowed timeframe. Therefore the following suggestions are presented to improve the fire protection features of the building and assure safe evacuation. <br /> <br /> Necessary measures<br /> <br /> • A 2,0 meter wide door leading straight to the outside, shall be installed in the north-west corner of the bleachers. Outside a fire escape with at least the same width as the door shall be installed.<br /> • A 2,0 meter wide door, shall be installed leading from the lower part of the bleachers to the restaurant. This requires removal of the tables between the new door and the stairs to the ground floor. The door shall open outwards in the evacuation direction. The door could also be placed so it leads straight to the outside in the north-east corner of the bleachers. This also requires a fire escape.<br /> • A fire escape shall be installed from the balcony of the VIP- and horse owners lounge.<br /> <br /> Secondary measures<br /> <br /> • Smoke ventilation should be installed where the bleachers are located by enabling automatic opening of every second window in the upper part of the glass wall upon smoke detector activation. <br /> • A door with fire classification EI 30 that closes automatically in case of fire should be installed between the kitchen and the restaurant. <br /> • The door below the stairs to the ground floor from the restaurant should be replaced by a door that is easier to open in an emergency, preferably with a crash bar.<br /> • Employee education, primarily for those working in the restaurant, in how to behave in a fire situation. Rapporten är ett examinerande moment i kursen Brandteknisk riskvärdering. Syftet med rapporten är att utvärdera personsäkerheten vid brand för besökarna på Halmstadtravet och ge förslag på eventuella förbättringar. Syftet är även att studenterna ska tränas i sin ingenjörsmässiga förmåga.<br /> <br /> I byggnaden som utvärderas finns bland annat restaurang, kök, sittplatsläktare och caféverksamhet. Det redogörs för det befintliga brandskyddet samt görs en jämförelse mellan befintligt brandskydd och BBR 20. <br /> <br /> För att utvärdera personsäkerheten vid brand väljs ett antal brandscenarier som ska utmana det befintliga brandskyddet. Brandscenarierna rangordnas efter sannolikhet och konsekvens. De brandscenarier som innebär störst risk simuleras i FDS där tid till kritiska förhållanden erhålls. Resultaten jämförs med utrymningssimuleringar som utförs i SIMULEX. Om utrymning inte kan ske säkert tas förslag på åtgärder fram och därefter genomförs känslighetsanalyser för att säkerställa robustheten hos lösningarna.<br /> <br /> Resultaten i rapporten visar att säkerheten inte är tillräcklig. För att uppnå en godtagbar säkerhetsnivå presenteras åtgärder vilka syftar till att förbättra personsäkerheten för besökarna på Halmstadtravet.<br /> <br /> Nödvändiga åtgärder<br /> <br /> • En dörr med bredden 2,0 meter som leder ut till det fria ska installeras i det nordvästra hörnet av läktaren. Utanför krävs en brandtrappa med minst samma bredd som dörren.<br /> • En dörr med bredden 2,0 meter som leder från läktarens nedre del in till restaurangen ska installeras. Detta kräver att de bord som finns placerade mellan den nya dörren och trappan till bottenplan tas bort. Dörren ska vara utåtgående i utrymningsriktningen, det vill säga öppnas in mot restaurangen. Alternativt kan dörren, då med tillhörande brandtrappa, leda direkt till det fria via det nordöstra hörnet av läktaren.<br /> • Utrymningstrappa från balkongerna utanför VIP- och hästägarloungen.<br /> <br /> Sekundära åtgärder<br /> <br /> • Installation av brandgasluckor på läktaren där vartannat fönster i den övre raden av fönster som vetter mot travbanan öppnas vid detektion. <br /> • Installation av en dörr mellan köket och restaurangen i lägst brandteknisk klass EI 30 med automatisk dörrstängning vid brand.<br /> • Dörren nedanför trappan till bottenplan från restaurangen bör bytas ut mot en dörr som är enklare att öppna i en nödsituation, förslagsvis en dörr med en så kallad panikregel.<br /> • Utbildning av personal, vilket främst gäller de som arbetar i restaurangen, i hur de ska bete sig vid brand. https://lup.lub.lu.se/student-papers/record/4452115/file/4452116.pdf application/pdf 2786382 no 2014 swe BBR brandscenario brandteknik brandteknisk riskvärdering BTR effektutveckling FDS Halmstadtravet kritiska förhållanden känslighetsanalys LTH personsäkerhet rökfyllnad SIMULEX travbana utrymning critical conditions department of Fire Safety Engineering evacuation fire safety evaluation fire scenarios heat release rate human safety racetrack sensitivity analysis smoke filling Technology and Engineering 4452115 2014-05-31T10:55:07+02:00 2014-06-10T09:47:00+02:00 2014-06-10T09:47:00+02:00

Anledningen till detta går att spåra i de kvaliteter som papper erbjuder och som tycks svåra att ersätta med digitala lösningar. 2010 kom de första av en ny generation pekplattor. Dessa blev snabbt populära. Bland annat var många svenska kommuner tidigt ute med att använda dem för att ersätta pappershandlingar på kommunsammanträden, så kallade papperslösa sammanträden. Hur det kommer sig att pekplattorna fått så stort genomslag i kommunerna trots de tidigare dokumenterade problemen med att ersätta papper är dock oklart. Uppsatsen ämnar därför undersöka kommunernas motiv till de papperslösa sammanträdena, samt huruvida kommunerna anser att införandet uppfyllt sina syften. För att ge svar på detta genomförs en kvalitativ undersökning där fem kommuner som infört papperslösa sammanträden med pekplattor intervjuas. Intervjuerna följer ett teoretiskt ramverk som tagits fram genom att studera relevant litteratur. Ramverket består av faktorer som antas påverka kommunernas beslut att genomföra införandet. Resultatet visar att kommunernas motiv till införandet av papperslösa sammanträden varierar. Vision och strategi, liksom miljö- och kostnadsbesparingar är de mest framträdande faktorerna. Resultatet visar också att kommunerna har sett nya möjligheter med pekplattorna, vilket tillsammans med teknikintresserade politiker tycks varit en pådrivande faktor. Kommunerna är själva mycket nöjda med införandet av pekplattorna och har inga planer på att återgå till pappersbaserade sammanträden. https://lup.lub.lu.se/student-papers/record/4456135/file/4456141.pdf application/pdf 1487745 no 2014 swe papperslösa sammanträden kommun beslut pekplatta läsplatta Technology and Engineering Business and Economics 4456135 2014-06-02T08:46:42+02:00 2014-06-17T15:17:33+02:00 2014-06-17T15:17:33+02:00

A vital phase of the radical innovation process is the first phase, called the Fuzzy Front End. Scholars claim that FFE activities are entailed with much complexity and uncertainty, yet crucial for a company’s competitive advantage. Innovation success is highly dependent on the integration between R&amp;D and Marketing, which tends to be low in large and mature companies. The effects of R&amp;D and Marketing integration in the FFE, when aiming to support radical innovation, have been little academically explored. Through conducting a case study on a Global Manufacturing Company, the study aims to better understand challenges and opportunities of increasing R&amp;D and Marketing integration in the Fuzzy Front End to support radical innovation. The study shows there are many external factors driving increased need for integration and physical barriers and different organizational responsibilities were considered the highest barriers for the case company. Most evident potential positive effects of increased integration were deemed: helping to grasp market and technology opportunities, making better business assessments and aligning goals and visions for the departments. https://lup.lub.lu.se/student-papers/record/4456247/file/4456465.pdf application/pdf 2632421 no 2014 eng Innovation Radical innovation Fuzzy Front End R&D and Marketing integration Large and mature companies Technology and Engineering Business and Economics 1651-0100 271 4456247 2014-06-02T11:49:12+02:00 2015-08-19T11:13:44+02:00 2015-08-19T11:13:44+02:00

The capital tied<br /> is believed to be too high, therefore Campbell Soup wants to lower their inventory levels.<br /> Purpose The purpose of this study is to do an extensive research resulting in long term suggestions<br /> on feasible batch sizes which are affected by campaigns and seasonality. The outcome of<br /> the study will be suggestions on how to lower the capital tied, while adhering to agreed<br /> customer service levels and looking at the total costs.<br /> Method Ten bouillons within the group Bong Dry Bouillon produced at the production line 102<br /> were investigated. The data for the study was collected by interviews, direct observations<br /> and by collecting quantitative and qualitative data. The methodical view used was the<br /> analytical view.<br /> Analysis The theories presented in the thesis were used to construct two models of the production<br /> and inventory of finished products of one year. The first one, called Current Situation<br /> Model, was based on real data and was used as a validation tool for the second model<br /> called Cost Analysis Model. In the Cost Analysis Model a distribution function was used to<br /> simulate a random stochastic demand and the Current Situation Model was used to<br /> validate if the chosen distribution function was good enough. Different scenarios were<br /> analyzed with the Cost Analysis Model to investigate the batch sizes sensitivity to different<br /> changes. With the Cost Analysis Model a batch size for each investigated product could be<br /> determined, which fulfills the case fill rate and has the lowest total varying cost.<br /> Conclusion Campbell Soup Nordic has very low inventory costs in comparison to the setup costs and<br /> manufacturing costs. It means it is more profitable for Campbell Soup Nordic, with regards<br /> to the summation of the varying costs depending on volume, to produce in larger batches<br /> for the products with high turn-over. The products with low turn-over should on the other<br /> hand be produced in smaller batches. If Campbell Soup Nordic wants to fulfill the gold<br /> standard of the service level in case fill rate they should continue with a safety time of two<br /> weeks. They should do this since a shorter safety time gives more lost sales which leads to<br /> not being able to fulfill the gold standard of a case fill rate of 99%. https://lup.lub.lu.se/student-papers/record/4456408/file/4456423.pdf application/pdf 5053395 no 2014 eng Batch size campaign case fill rate gamma-distribution holding cost manufacturing cost seasonality setup cost and simulation model.

studentPublicationsM1 Sven Paulin Nilsson author Daniel Stenbeck author Gösta wijk supervisor Production Management v1000259 department Svensk modeindustri växer kraftigt och har de senaste åren fått allt större uppmärksamhet. Branschen sysselsätter nu fler än traditionella svenska industrier som stål och livsmedel och uttryck som det svenska musikundret har fått ge vika för det svenska modeundret. Den svenska marknadens begränsade storlek gör att de svenska modeföretagen tidigt tvingas utomlands för att bli bärkraftiga och nå önskade försäljningsvolymer, samtidigt som företagens resurser ofta är begränsade. Detta examensarbete syftar till att utreda vilka faktorer som påverkar förutsättningarna för svenska modeföretags etablering på utländska marknader samt hur dessa faktorer kan ligga till grund för utformningen av en framgångsrik internationaliseringsstrategi. Ett företags internationaliseringsstrategi avser både val av marknader, etableringsmetod såväl som hur marknadsnärvaron skall utvecklas över tid. Det övergripande målet är att företaget skall bli så lönsamt som möjligt.<br /> Genom att studera existerande teori kunde 17 faktorer, som på olika sätt och i varierande omfattning påverkar ett företags internationaliseringsstrategi, identifieras. Dessa faktorer kan delas in i fem kategorier: interna, externa och strategiska faktorer samt önskade metodegenskaper och typ av kunskap. Nio framgångsrika svenska born-global företag verksamma inom modeindustrin studerades sedan för att få en bild av hur de resonerat under sina internationaliseringar. Med denna empiriska kunskap kunde sedan de 17 faktorernas relevans verifieras för aktuell bransch och tillsammans bildade de en ny modell, Stenbeck och Paulins modell.<br /> Det visade sig att modellen med dess 17 ingående faktorer på ett tillfredsställande sätt kunde ge en förklaring till de studerade företagens framgång. Även om företagen inte utvärderar samtliga faktorer medvetet såg vi att alla ingående faktorer, om än i varierande grad, påverkar ett företags internationaliseringsstrategi. Det gäller vid val av marknader, val av etableringsmetod såväl som när och hur marknadsnärvaron ska förändras över tid.<br /> Genom att analysera modellens samtliga faktorer och ta hänsyn till vilka faktorer som specifikt företag värderar högst och anser vara mest relevanta kommer den sammanvägda analysen peka åt antingen en hierarkisk marknadsnärvaro eller en icke hierarkisk marknadsnärvaro. Vi ser att vid de tillfällen som företag misslyckats med sin etablering på en ny marknad har de i regel avvikit från presenterad modell, att de viktigaste faktorerna inte legat i linje med vald etableringsmetod på aktuell marknad. https://lup.lub.lu.se/student-papers/record/4456426/file/4456432.pdf application/pdf 1491259 yes 2014 swe Internationalisering strategi marknadsval etableringsmetod modeföretag born global Technology and Engineering 145485 4456426 2014-06-02T14:44:23+02:00 2014-06-02T14:52:12+02:00 2014-06-02T14:52:12+02:00

As a consequence, the organization is facing challenges related to its organizational identity. From a theoretical perspective, organizational identity consists of an internal and an external part that together dynamically construct the identity. In case of an unbalance between the internal and the external part, there is a risk of impairing the organizational health. This effect is not, however, further investigated in existing theory.<br /> <br /> Purpose:<br /> The main purpose of this study is to gain insights into how a temporary disassociation between the internal and the external definition of organizational identity is affecting organizational health. Further, the sub-purpose is to illustrate Vattnadahl in the light of identity dynamics and from this investigate if those with power within an organization have greater influence of the identity balance.<br /> <br /> Methodology:<br /> This study was conducted from a qualitative and inductive approach and was performed as a case study at Vattnadahl. From this, collection and compilation of empirical data at Vattnadahl initiated the study. Subsequently, a literature study was conducted in order to explain the phenomena found at Vattnadahl. Finally, the case company was analyzed from an analytical framework developed by the authors.<br /> <br /> Conclusions:<br /> Summarizing the study, it can be concluded that Vattnadahl has an unbalanced identity strongly influenced by their external image. Consequently, the organization is experiencing the dysfunction of hyper-adaptation, which is affecting their organizational health. This effect can be compiled into six unhealthiness factors; stress, frustration, confusion, lack of pride, anxiety, and lack of initiative. Furthermore, it can be concluded that those with power within Vattnadahl have a greater influence on the identity balance compared to other employees.<br /> <br /> The thesis also provides a development of the construction of possible dysfunctions occurring from an unbalanced identity, by questioning the existing definitions and nuancing the concepts. The nuancing of the concepts is divided into two perspectives; a stakeholder perspective and a nuanced grading perspective. The stakeholder perspective implies that the dysfunction could differ depending on which stakeholder that is in focus of the analysis. The nuancing grading perspective indicates a possibility for dysfunctions to simultaneously exist, but in different strengths, such as softer or stronger. https://lup.lub.lu.se/student-papers/record/4456451/file/4456453.pdf application/pdf 1476468 no 2014 eng organizational identity identity dynamics image organizational culture organizational health hyper-adaptation organizational narcissism Technology and Engineering Business and Economics 1651-0100 265 4456451 2014-06-02T15:03:21+02:00 2016-02-04T15:11:15+01:00 2014-07-17T07:39:48+02:00

This is also to say, that perception of the web – present and past – is shaped and governed by the media we and our machines perceive it with. So with what media do we archive it? Recording media is a largely unexplored factor in the preservation of the web and archival science in general, and the question requires rethinking.<br /> <br /> This Master&#39;s thesis examines a prominent instrument used for archiving the web – the software Heritrix – as a technical recording medium. As a contrast and background to Heritrix, the electronic legal deposit law recently enacted in Sweden is written as another medium used to transmit content published online. My research question is, how does Heritrix work as a archiving medium?<br /> <br /> Heritrix is shown to be technical in the sense that it inscribes, without human intervention and without any respect for human discourse, signals that reach it, much like how a photographic plate indiscriminately registers and inscribes light by chemical reaction. It is a recording medium in the sense that the transmission traverses across time as well as space. To enable the study of Heritrix as medium, I employ a media archaeological method inspired mainly by the media theory of Friedrich Kittler. By carefully delimiting my study Heritrix is as far as possible considered on its own terms, to build an diagrammatic description of the medium and the way it fits into our contemporary discourse network.<br /> <br /> Four epistemological configurations and one time perspective create a full description, and the disparity between the electronic legal deposit law and Heritrix is shown to be massive, with Heritrix being a technical medium while the electronic legal deposit law remains an artistic medium. https://lup.lub.lu.se/student-papers/record/4456676/file/4456678.pdf application/pdf 346085 no 2014 swe Web crawler medium archival science web preservation media archaeology History and Archaeology Arts and Architecture Technology and Engineering 4456676 2014-06-02T21:52:50+02:00 2014-06-18T14:26:21+02:00 2014-06-16T14:37:34+02:00

To diminish this threat it’s of <br /> great importance that adequate time for evacuation is available. In this paper students at the Fire Protection Engineering program examine the system that is currently in place to ensure the safety of guests and personnel at Arken Hotel &amp; Art Garden Spa. This is done by setting acceptable risk criteria, evaluating risks, determining available and required time, analyzing the effects of important factors <br /> and finally reaching a conclusion about personal safety. The method involves literature studies, calculations, simulations and logical thinking. Where the safety is found inadequate different solutions are examined and recommended. The examination shows that the safety of guests cannot be completely guaranteed in all parts of the hotel without a few building modifications to reach the acceptable criteria. https://lup.lub.lu.se/student-papers/record/4456786/file/4456792.pdf application/pdf 5676581 no 2014 swe Fire safety evaluation FSE Fire scenario Simulex FDS CFAST Hotell Arken Hotell & Art Garden Spa human safety escape critical conditions risk analysis sensitivity analysis Technology and Engineering 4456786 2014-06-03T10:59:23+02:00 2014-06-10T09:46:49+02:00 2014-06-10T09:46:49+02:00

Since academia agrees that value based pricing is superior for creating profit, the problem is not in identifying an ideal pricing strategy, but to understand and facilitate the transformation process towards value-based pricing. Only a limited amount of research has so far been put on understanding the sales force; the part of the organization which will ultimately carry out the operational changes. The authors argue that it is of great importance to get their buy-in, and therefore aim to understand what obstacles the members of the sales force perceive in value-based pricing.<br /> Purpose: To refine and further develop existing knowledge on how to facilitate value-based pricing transformation.<br /> Method: The study was performed using triangulation by combining qualitative and quantitative research methods. First, members of the sales force at Informatikka were interviewed in order to produce proposals and hypotheses on what would hinder sales force buy-in. These were then tested in a questionnaire sent out to a larger share of the total population. <br /> Conclusions: The interviews found eight obstacles perceived by the sales force at Informatikka. The perceived severity of the obstacles seemed to be dependent on previous experience of value-based pricing, which was confirmed by the questionnaires. https://lup.lub.lu.se/student-papers/record/4456917/file/4456918.pdf application/pdf 1713569 no 2014 eng Value-based pricing value-based pricing transformation pricing capabilities sales force obstacles buy-in.

A strong reflection can have a negative influence on speech or music that is transmitted from the source to the receiver. Impulse responses including different strength of a reflection are modelled using a statistical model. From the impulse response, different parameters describing the strength of the reflection can be calculated and the detection thresholds for the parameters are found from listening tests.<br /> Three different parameters were compared, of which one is an existing parameter by Dietsch and Kraak and the other two are new parameters based on the energy decay curve of the impulse response. The threshold is given as the minimum level at which the subject can hear the reflection by listening to the impulse response. The detection threshold is found from impulse responses for rooms with different volumes and reverberation times and for different delay times of the strong reflection. The performance of the parameters is then discussed and a suggested technique for identifying and evaluating a strong reflection is given. https://lup.lub.lu.se/student-papers/record/4456992/file/4456993.pdf application/pdf 1765792 no 2014 eng Technology and Engineering http://www.akustik.lth.se/ 0281-8477 TVBA--14/5045 4456992 2014-06-03T16:58:03+02:00 2014-10-24T13:53:57+02:00 2014-10-24T13:53:57+02:00

Therefore, global banking regulations exist to ensure that banks keep enough capital for the risks they are taking. One such risk is name credit concentration risk, arising when exposures in a portfolio have a skew distribution across different counterparties. Regarding the treatment of this particular risk, Finansinspektionen gives guidance on how Swedish banks and financial institutions could approximate it. They do so by proposing two methodologies, one within a Standardised Approach and one within the more advanced Internal Ratings-Based (IRB) Approach. A comparison between the resulting capital requirements for Finansinspektionen’s two proposed methodologies do not publicly exist. Performing such a comparison for portfolios with different characteristics, including a third parameter, would add to previous research. The comparison would also provide Swedish banks and institutions with additional knowledge of the differences in resulting capital requirements when applying Finansinspektionen’s two proposed methodologies on their portfolios. Thus, the authors have compared these methodologies. The thesis is performed through a quantitative study of generated realistic portfolios and of Ikano Bank’s leasing portfolio, where two methodologies for approximating capital requirement for name concentration risk are applied on the portfolios. Theory used is the methodologies proposed by Finansinspektionen, i.e. the Standardised Approach and an IRB Approach; a Granularity Adjustment according to Michael Gordy and Eva Lütkebohmert. The major conclusion of the thesis is that the relationship between a portfolio’s large and small exposures in terms of assigned PDi is of great importance for how the two methodologies’ resulting capital requirements differ. To further clarify, it is this relationship that affects the difference in capital requirements between the two methodologies, rather than the actual levels of PDi for the big and small exposures. https://lup.lub.lu.se/student-papers/record/4457017/file/4457030.pdf application/pdf 2072896 no 2014 eng Granularity Adjustment Capital Requirement Name Concentration Risk Credit Risk Standardised Approach Basel agreements Mathematics and Statistics Business and Economics Technology and Engineering 1651-0100 268 4457017 2014-06-03T18:27:09+02:00 2014-09-01T10:45:33+02:00 2014-09-01T10:45:33+02:00

At the same time, construction companies must increase their profitability. This requires the development of systems for improved communication and interaction. Especially now when the industry is facing massive retirements, there is a risk that knowledge will be lost. To ensure quality the companies also need to involve their employees so they take greater responsibility. The intention with the report is to study the possibilities for construction companies to create a more efficient building process through making better use of the employees’ qualifications. Problems with communication, planning and the working environment have been identified in the background of this report and they have been the starting point for this report. Representatives from six construction companies, of different sizes and in different stages of development, have been interviewed. This method was chosen in order to give a broad picture of how the construction industry can be more efficient. The research question is based on the idea that a construction company could use their employees’ qualifications better, by improving communication and interaction. This statement is shown to be true and improvement can be achieved by applying different efficiency concepts and their recommended actions through activities. Most efficiency concepts advocate experience feedback and regular meetings. Regular meetings was one of the activities that was most used and which also was adapted to the company’s own organisation. The activities that were shown to be the most profitable to invest in are experience feedback, visual communication and joint planning of work preparations. Joint planning and experience feedback throughout the building process are excellent ways to improve the use of available knowledge. The results of this report are of importance for construction companies who have problems with communication and interaction. To succeed with this strategy, the company should also be imbued with the ambition to constantly evolve. Because a key point to improve efficiency is to create a work environment that engages employees and gives them the opportunity to contribute to the development. https://lup.lub.lu.se/student-papers/record/4457484/file/8961716.pdf application/pdf 2439178 no 2014 swe kompetens samverkan kommunikation yrkesroller byggprocessen effektiviseringskoncept Technology and Engineering 4457484 2014-06-02T00:00:00+02:00 2018-10-18T10:28:27+02:00 2014-06-04T00:00:00+02:00

The idea behind the service is, throughout the entire supply chain, to measure temperature and microbial growth using sensors attached to the package. The information will at certain points in the supply chain be sent to a cloud service that calculates the remaining shelf life by using prediction algorithms.<br /> <br /> The aim for this study is, from a business perspective, to analyze the opportunities and challenges in the implementation of a DSLP service in a supply chain and also the effect it would have on the studied 4PL company’s business model (Bring Customer Solutions). The method that is used is a single case study on one of the food supply chains that the case company coordinates. The data collection consists of literature findings, interviews and study visits. Six different areas of study are researched which has been put together into a theoretical framework that has served as a basis when developing an analysis framework to answer the research questions.<br /> <br /> The findings show that there are many opportunities connected to the DynahMat project such as being able to guarantee the quality of the supply chain and the goods it delivers. Other opportunities are increased track- and traceability of the goods and also more visibility, collaboration and information sharing in the supply chain which can have a positive effect on its performance. In addition, the DSLP service offers the possibility to easier measure the supply chain performance. There are also challenges with the DSLP service. For example, it is important to convince all actors to cooperate and make the necessary investments. The increased visibility in the supply chain will also make the actors more exposed and accountable for their performance. Another challenge is the extended requirement on coordination and communication. Moreover, it can be determined that the 4PL’s business model will change on several points. For example, the supply planning needs to be changed to a more reactive approach, new technology needs to be implemented and there will be a higher degree of transparency to the customer and the logistics providers. https://lup.lub.lu.se/student-papers/record/4457499/file/4457503.pdf application/pdf 2840611 no 2014 eng DSLP Service DynahMat Dynamic Shelf Life RFID Biosensors Supply Chain Management Business Model Coordination Information Sharing Transparency 4PL company Technology and Engineering ISRN 14/5120 4457499 2014-06-04T07:39:57+02:00 2014-06-04T09:55:38+02:00 2014-06-04T09:55:38+02:00

The entire construction load is then taken by the non-composite steel sections. Bracing may be needed to make the slender girders rigid enough to resist lateral torsional buckling during this phase. If temporary formwork could be attached and be shown to work as torsional bracing; material could be saved and the construction phase could be safer.<br /> <br /> Within this thesis some of the commonly used temporary formworks are described and analyzed to see if some of them could work as discrete torsional bracing. Findings from this investigation were that the often used formwork system CUPLOK was easy and suitable to be modified and attached to the girders as discrete torsional bracing. <br /> <br /> With the modified CUPLOK system attached, three different systems were numerically analyzed using the finite element program Abaqus. One with formwork attached to a laboratory test beam set-up with dimensions according to Mehri and two on real bridges with trapezoidal respective I-girder cross section.<br /> <br /> Findings from analyzes were that with the modified CUPLOK system attached, the stiffness were increased dramatically on the slender I-girder system and also, but relatively less, on the less slender real bridge I-girder system. No stiffening effect was shown on the specific trapezoidal cross section analyzed herein. <br /> <br /> Finally the findings are discussed and further research proposed. https://lup.lub.lu.se/student-papers/record/4457607/file/4457614.pdf application/pdf 2973502 no 2014 eng temporary formworks stabilizing concreting bracing bridge girders Technology and Engineering 0349-4969 5231 Examinator: Roberto Crocetti 4457607 2014-06-04T12:29:49+02:00 2014-06-14T08:52:44+02:00 2014-06-14T08:52:44+02:00

A literary review of the basic theory is performed, which clearly shows the theoretical relation between natural frequency and axial loading of linear structural elements (strings &amp; beams). Current journal articles show that research has been done on mathematical models as well as some experimental studies. Basic theory and current research show that the impact of support conditions is of great importance to the relation between frequency and load. Thus an approach which models the support conditions as unknowns (springs) is suggested and used in the remainder of the study. The method requires the measurement of both the natural frequency and the corresponding mode shape for calculation purposes.The calculations are performed using both an analytical and a discrete approach. Numerical testing shows that the method is highly sensitive for the measured shape of the vibration mode. Testing of the discrete algorithm has shown stability/convergence issues if the discretization level is too detailed. However the ability to use an excess of measurement points than necessary (overdetermined system) to describe the mode shape seems to overcome some stability issues. The experimental studies to date have mainly focused on tensile tests performed on slender structures. Laboratory testing on four compressive samples with varying slenderness is performed in order to investigate the applicability on real-life structures. Testing results show that the presented approach yields loading estimates highly sensitive to the mode shape. Estimation quality is significantly improved by the use of excess shape measurements. Also the load estimations seem to overestimate the magnitude of loading. The use of both Bernoulli-Euler and Timoshenko beams show that the former tends to yield even higher estimates of loading. The study shows that the suggested method is promising for axial load identification, yet further investigations are required. Specifically improvements to the measurement/calculation of the mode shape are necessary. https://lup.lub.lu.se/student-papers/record/4457808/file/4457813.pdf application/pdf 10100471 no 2014 eng Technology and Engineering 0349-4969 TVBK-5233 https://lup.lub.lu.se/student-papers/record/4457808/file/4457816.pdf application/pdf no Examinator: Per-Erik Austrell 4457808 2014-06-04T14:58:29+02:00 2014-06-14T08:50:09+02:00 2014-06-14T08:50:09+02:00

Despite of the possibility, investments in sustainable retrofit of building blocks are not prioritized among property owners. Instead, projects with a higher profit are chosen. Therefore, it is essential to scrutinize the decision-makers motivation during this investments and how the profitability are measured among property owners. <br /> The purpose of this master thesis is to highlight the property owners’ priorities and considerations when investing in energy-efficiency packages during sustainable retrofits. The study is designed with an explorative approach, where the phenomenon can be studied with a qualitative method. It is a combination of multiple case-studies and an interview study, which have been analyzed with the foundation of a theoretical framework consisting of investment planning and retrofits. The property owners prioritize the following aspects when investing in energy-efficiency packages during sustainable retrofits; the building&#39;s requirements, packages with a small investment cost, decrease operation costs and the property management. The building’s technical requirements determine the possibilities of investment and the available capital crucial. Three dimensions can be identified for the profitability assessment, to the extent of a formalized process; standardized (formal), routine and experience based (in formal).

Dock väljer många fastighetsägare bort investeringar i energieffektiviserande åtgärder till förmån för projekt som anses vara mer lönsamma. Därmed är det av intresse att undersöka hur fastighetsägarna motiverar sina val vid investeringar i energieffektiviserande åtgärder och hur de bedömer lönsamheten i åtgärderna. <br /> Syftet med det här examensarbetet är att belysa vad fastig-hetsägarna beaktar vid en investering i energieffektiviserande åtgärder vid renovering av flerbostadshus. Studien utgår från en explorativ ansats, där ett empiriskt fenomen studeras utifrån en kvalitativ metod. Den är utformad som en kombination av multipla fallstudier och intervjustudier, som har analyserats utifrån ett teoretiskt ramverk inom investeringsbedömning och val av energieffektiviserande åtgärder. Fastighetsägarna prioriterar följande faktorer vid en investering i energieffektiviserande åtgärder vid en renovering; fastighetens behov, åtgärder med en liten investeringskostnad, minska fastighetens driftskostnad samt förvaltning av fastig-heten. Fastighetens tekniska behov avgör möjligheten till in-vestering, därefter är det ekonomiska investeringsutrymmet avgörande. Tre mönster synliggörs vid fastighetsägarnas vid lönsamhetsbedömning, utifrån graden av formalisering; stan-dardiserad (formell), slentrianmässig samt erfarenhetsbaserad (informell). https://lup.lub.lu.se/student-papers/record/4459662/file/4459702.pdf application/pdf 2373550 no 2014 swe fastighetsägare beslutsunderlag investeringsbedömning renovering Energieffektiviserande åtgärder Technology and Engineering Business and Economics 1651-0100 264 4459662 2014-06-05T12:13:06+02:00 2015-08-19T11:14:00+02:00 2015-08-19T11:14:00+02:00

The reason for the standardization of the train control command system is to increase the competitiveness of the railway by promoting the ability to run the same train from one end of Europe to the other, without the need to change locomotives and drivers. The train control command system that was chosen by the European Union is ERTMS which stands for European Rail Traffic Management System. Initially, the ERTMS will be introduced on eleven (11) corridors that stretch throughout Europe. Sweden is involved in the corridor known as the Corridor B, which runs between Stockholm and Naples. The portion of Corridor B located in Sweden will be completed by 2020. Sweden has chosen to replace the existing ATC-system with ERTMS on all railways throughout Sweden. The study is an opinion-based qualitative study of the Swedish railway industry&#39;s views on the European train control command system ERTMS. To set ERTMS in proportion the positive and negative aspects of ERTMS was compared with the existing system ATC. The study is focused on the key factors: Finance, Information, Technology and Industry expertise. The substrate was collected through qualitative interviews of railway operators from the following categories: Infrastructure manager, Suppliers and Construction planners. The selection of interviewees was made using chain sampling. The interviews were analyzed and processed with the analytical sense concentrator. The result is presented under the respective key factor with an added factor for other opinions. This is illustrated by a chart with the positive and negative aspects that emerged from the interview responses. Under each chart is an analyzing text that describes the industry&#39;s mutual opinion. The railway industry is cautious towards ERTMS. For the motivation towards ERTMS to properly appear, it will require a general increase of knowledge about ERTMS, in the entire industry. https://lup.lub.lu.se/student-papers/record/4460281/file/8961717.pdf application/pdf 3578961 no 2014 swe ertms atc järnväg signalsystem kvalitativa intervjuer meningskoncentrering åsiktsbaserad studie Technology and Engineering 4460281 2014-06-05T00:00:00+02:00 2018-10-18T10:28:29+02:00 2014-06-06T00:00:00+02:00

Något denna plånbok däremot inte innehåller är en motsvarande lösning för legitimationen, ett plastkort som i digitaliseringen inte verkar ha någonstans att ta vägen. Faktum är att legitimering med smartphonen blev möjligt i takt med lanseringen av Mobilt BankID år 2011. Denna elektroniska legitimation är dock bunden till kontexten av e-tjänster och fyller således inte funktionen av att i en fysisk legitimeringssituation kunna agera substitut för exempelvis körkortet. Oavsett vilken riktning den digitala plånboken kommer ta gällande legitimationen finns idag inget underlag för hur en elektronisk legitimering i en fysisk kontext skulle gå till. Det är således även oklart hur de potentiella användarna ställer sig till en sådan artefakt. Med dessa oklarheter som grund ämnar uppsatsen tillhandahålla den artefakt som möjliggör elektronisk legitimering i en fysisk kontext, och vidare att undersöka användarnas acceptans för denna. För att ta itu med detta tar vi hjälp av relevant litteratur för att identifiera de teoretiska ramverk genom vilka artefakten ska designas och utvärderas. Influerade av designforskning utgår vi från designteori av Gregor och Jones (2007) för att tillhandahålla artefakten. Utvärderingen utgår från Davis (1986) Technology Acceptance Model och genomförs i form av en kvantitativ enkätundersökning. Resultatet visar att elektronisk legitimering teoretiskt sett bör fungera i en fysisk kontext, men att vidare designforskning krävs innan detta blir möjligt. Studien visar även att de potentiella användarna anser att Mobilt BankID hade varit ett bra komplement till den fysiska legitimationen, men att avsikten att använda e-legitimationen i en fysisk legitimeringssituation minskar då den fysiska legitimationen upplevs vara det föredragna alternativet. https://lup.lub.lu.se/student-papers/record/4461060/file/4461061.pdf application/pdf 2498104 no 2014 swe E-legitimation Mobilt BankID design theory designstudie TAM Technology and Engineering 4461060 2014-06-09T00:22:54+02:00 2014-06-17T15:15:39+02:00 2014-06-17T15:15:39+02:00

This architectural style and a growing demand for illuminated space require buildings to be designed with larger facade openings. The diculty with this is that the masonry superstructure will be loaded by large shear forces, while at the same<br /> time its shear capacity is limited. To handle this issue today there are dierent types of methods but they are either economically unsustainable or not good enough. <br /> The purpose of this masters thesis was to investigate and nd a solution to this problem that is sustainable from both an economic and practical perspective. First of all a comprehension regarding masonry limitations was established, to be able to set realistic goals. Then a survey was carried through to weigh dierent alternatives against each other.<br /> Thereafter, the work was followed out by two mathematical parameter studies which were based on a brick-concrete combined beam and a straight-out reinforced concrete beam. The rst research proved that masonry is quite limited in its ability to work as a beam structure. The study of reinforced concrete beams with appropriate geometry gave indications that pointed to that the desired resistance was achievable. https://lup.lub.lu.se/student-papers/record/4461091/file/4461092.pdf application/pdf 18888227 no 2013 swe Technology and Engineering 0349-4969 TVBK-5219 https://lup.lub.lu.se/student-papers/record/4461091/file/4461094.pdf application/pdf Populärvetenskaplig artikel no Examinator: Johan Jönsson 4461091 2014-06-09T08:49:50+02:00 2014-06-12T15:35:38+02:00 2014-06-12T15:35:38+02:00

According to the American standard ACI 349, which is also used in Sweden, two limits should be carefully considered. These temperature limits are 66°C (150°F) and 93°C (200°F). Previous studies usually focus on concrete subjected to fire, thus the aforementioned moderate temperature loads are not widely studied in the aspect of strength in concrete. <br /> The purpose of this master thesis is to gather information on the subject and perform tests on concrete which have been subjected to moderate elevated temperatures. A better understanding of how well the conditions of different reactor vessels can be evaluated based on the gathered information. The main purpose is to investigate compressive and tensile strength but also changes in the modulus of elasticity and weight loss. https://lup.lub.lu.se/student-papers/record/4461103/file/4461112.pdf application/pdf 10984025 no 2013 swe Technology and Engineering 0349-4969 TVBK-5220 https://lup.lub.lu.se/student-papers/record/4461103/file/4461114.pdf application/pdf Populärvetenskaplig artikel no Examinator: Sven Thelandersson 4461103 2014-06-09T09:03:24+02:00 2014-06-12T15:32:33+02:00 2014-06-12T15:32:33+02:00

A robust building is characterized by the fact that the consequence of local damage is never more severe than the initial event. The way in which structural robustness is approached in the design of a building differs a great deal from one structural engineer to another. For a structure in consequence class 2b or higher, Eurocode requires that at least one out of three alternatives (indirect method, direct method, key element) is applied. Guidance for when and how to apply each method is appalling or completely missing. In addition to this, there are two different parts of Eurocode (EN 1991-1-7 and EN 1992-1-1) treating the subject and for a given set of circumstances, result in different design tensile forces. It’s difficult to conclude which part of Eurocode and which set of equations to apply. This leads to a situation where each structural engineer has to make his own individual interpretation of the code. However, by researching, reasoning and by mapping arguments from structural engineers with varying academic backgrounds (structural engineering consultants, professors and PhD students) it’s possible to identify interpretations that are more rational than others. https://lup.lub.lu.se/student-papers/record/4461263/file/4461292.pdf application/pdf 3497696 no 2013 swe progressive collapse consequence class 2b robustness Eurocode vertical tie horizontal tie alternative load-path catenary action prefabricated concrete Technology and Engineering 0349-4969 TVBK-5224 https://lup.lub.lu.se/student-papers/record/4461263/file/4461299.pdf application/pdf Populärvetenskaplig artikel no 4461263 2014-06-09T10:44:15+02:00 2014-06-12T15:33:20+02:00 2014-06-12T15:33:20+02:00

Befolkningen upplevde en stor bostadsbrist, som krävde akuta lösningar. Beslutet som landets politiker tog, var att bygga en miljon bostäder på ett snabbt och effektivt sätt. Målet var att minska bostadsbristen, tillfredsställa hyresgästernas behov samt ge dem en högre levnadsstandard. Under projekteringen och produktionen låg fokus på effektivisering och standardisering av arbetet. Detta resulterade i nya byggtekniska lösningar som än idag används och utvecklas. Miljonprogramshusen byggdes under en tidperiod då det endast förekom ett fåtal energikrav. I dagsläget står miljonprogramshusen inför behov av stora renoveringar. Synen på bostäder har förändrats och nya byggkrav har införts.Energistatusen är en av de viktigaste parametrar som i dagsläget ligger i fokus. Nya hus byggs och gamla renoveras, för att vara energisnåla samt få en hög levnadsstandard som motsvarar dagens krav. Offerkällan är hyresfastigheter byggda under miljonprogramsperioden, 1967- 69, av LKF, Lunds Kommuns Fastighets AB. I dagsläget utförs en renovering av dessa hus som snart är färdigställd. Under renoveringsarbetet valdes den bästa tekniska lösningen både med hänsyn till energistatus samt ekonomi. I denna rapport redovisas den beräknade energistatusen både före och efter renoveringen. Förslag på kompletterande åtgärder för att sänka energiförbrukningen, utan hänsyn till ekonomidelen, har angetts. Resultatet visar att den utförda renoveringen av bostadsområdet inte gav högre effekt- och energiklasser. Renoveringsåtgärderna som LKF genomförde kunde inte minska energianvändningen, därmed kunde inte de gällande krav från BBR uppnås. Detta innebär att det kommer att krävas ytterligare åtgärder med hänsyn till de satta miljömålen år 2020. De förbättrade åtgärderna som föreslås i denna rapport ger lägre energianvändning, vilka uppfyller gällande krav från BBR. https://lup.lub.lu.se/student-papers/record/4461716/file/8961718.pdf application/pdf 5105106 no 2014 swe miljonprogramshus energieffektivisering isolering bostäder renovering hållbart Technology and Engineering 4461716 2014-06-09T00:00:00+02:00 2018-10-18T10:28:33+02:00 2014-06-10T00:00:00+02:00

Today’s system has soon reached the end of its lifecycle period and therefore need to be replaced. Meanwhile, decisions within the EU have been taken to improve interoperability between European countries. The solution will be an international control system replacing the different national train control and command systems in Europe. The new system is referred to ERTMS. To develop the system nationally early deployment lines have been developed where testing and adaptation to the Swedish network occurs. The purpose of this study is to create a description of the most common unforeseen stoppages that the experimental lines have experienced, and thereafter suggest potential solutions or opportunities for improvement. The report is divided into three parts, the first part is a description of the unforeseen stoppages, including categorizations and descriptions. The second part includes analysis of these problems and whether any solutions can be developed and if so, how. The third and final section is a compilation of the two previous parts and provides a broad overview. All three sections are based on interviews with respondents who previously were, or currently are, involved in the project. In all three parts the unforeseen stoppages have been categorized depending on the source of the specific disturbances. Based on these categories it clearly shows that the spread has been great regarding the origin of the disruption. The complications encountered were of both technical and administrative nature. The technical disruptions were reduced to locate in the ground and onboard equipment while disruptions regarding education, contracts and collaboration between the parties depend on administrative complications. The technical disruptions regarding ground and onboard equipment is in the state that it mostly can be repaired through system updates. The disruptions that do not origins from technical disruptions can potentially be repaired with improved theoretical methods. For the implementation of ERTMS to achieve its potential success it is required that the material provided in the educations is sufficient to each profession within the train control system. Furthermore should there be clarification at the beginning of a contract between the two participants. It is of great importance that respectable collaboration between the participating parties is established which include openness and transparency. In that way misunderstandings and inaccuracies can be reduced. https://lup.lub.lu.se/student-papers/record/4461720/file/8961719.pdf application/pdf 1507447 no 2014 swe ertms pilotbanor driftstörningar mark- och ombordutrustning utbildning kontrakt erfarenhetsdrift Technology and Engineering 4461720 2014-06-06T00:00:00+02:00 2018-10-18T10:28:35+02:00 2014-06-10T00:00:00+02:00

The project was carried out in cooperation with the company Tactel AB. They see a great commercial potential in a tool that can provide application publishers with information about users’ frustration levels in real-time. The objective of the project was to develop a prototype for such a tool, which measures relevant user behavior, detects deviations and visualizes information about behavior deviations in large user populations. During the project a prototype was developed, EmoTouch, consisting of two parts: the Android module EmoTouch Android SDK and the web application EmoTouch Dashboard. The module measures various parameters in the user’s interaction with an application. Parameters were selected for measurement based on the results of previous studies, where correlations between user behavior and affective responses were examined. A user-specific profile is established as behavior is measured. The profile is used to detect parameter values that deviate from the user’s normal behavior. Through analysis of such deviations, behavior is categorized as either frustrated or non-frustrated. In order to enable EmoTouch to combine data from large user populations, it was implemented as a plugin to Google Analytics. EmoTouch Dashboard retrieves and visualizes this data. In order to examine EmoTouch’s ability to detect frustration, tests were conducted with test subjects. The test subjects interacted with an Android application, first in a normal way, and then with a simulated frustrated behavior. The results of the tests showed a relation between the proportion of deviating parameter values and simulated frustrated behavior, which indicates the possibility of detecting frustration based on EmoTouch’s method for mapping user behavior. EmoTouch could not differentiate between normal and simulated frustrated behavior, however analysis of the test results revealed ways of improving the method for identifying frustration. The project has shown how user behavior can be mapped in an arbitrary Android application, how deviating behavior can be detected and how information about the behavior of large user populations can be visualized. The project has also shown how Google Analytics can be utilized as a platform in order to create a more powerful tool. https://lup.lub.lu.se/student-papers/record/4461724/file/8961720.pdf application/pdf 1974877 no 2014 swe android användarbeteende google analytics frustration analysverktyg för mobilapplikationer Technology and Engineering 4461724 2014-06-05T00:00:00+02:00 2018-10-18T10:28:37+02:00 2014-06-10T00:00:00+02:00

studentPublicationsH3 Thomas Daun author Anders Robertsson supervisor Björn Olofsson supervisor Rolf Johansson supervisor Department of Automatic Control v1000253 department The demand of today for advanced manufactured parts with high precision is due to the increasing complexity of technologies. The parts are typically made by CNC (Computer Numerical Control) machines, which are expensive and comparably big. By using industrial robots that are significantly cheaper, reduced costs can be achieved, which is particularly beneficial for small and medium enterprises. Robots are, however, less stiff and strong and are less accurate compared to the CNC machines.<br /> <br /> In this thesis, the idea was that by designing a controller, this could be compensated for so that the robot could perform machining with high precision. The research made in this thesis was part of the EU co-funded research project COMET.<br /> <br /> The robot task was to repeatedly mill parts with improved results. Iterative Learning Control (ILC) was therefore chosen as a suitable control strategy for this task. It uses the position error from previous iterations and adds it to the control signal to converge the output to successful results. Results showed that when using ILC for tracking paths, the position error could be reduced with approximately 11-20% in x, y, and z directions after one iteration. https://lup.lub.lu.se/student-papers/record/4462212/file/4462448.pdf application/pdf 2579283 no 2014 eng Technology and Engineering 0280-5316 ISRN LUTFD2/TFRT--5942--SE https://lup.lub.lu.se/student-papers/record/4462212/file/4462457.pdf application/pdf no 4462212 2014-06-10T14:55:32+02:00 2014-06-13T11:18:16+02:00 2014-06-13T11:18:16+02:00

Med en växande användarbas och en kostnad som nästan alltid är obefintlig är det naturligt att företag ser open source som ett alternativ till att köpa proprietär mjukvara. Genom denna uppsats undersöker vi därför vilka egenskaper hos open source som är viktiga och mindre viktiga när beslut om att använda den typen av mjukvara tas, och om IT-företag idag över huvud taget överväger att använda open source. För att svara på detta skapas ett teoretiskt ramverk med totalt sex faktorer som baserat på tidigare forskning och litteratur är de vanligast förekommande egenskaperna hos open source. Fyra stycken intervjuer genomförs sedan med små till medelstora IT-företag där frågorna baseras på ramverkets sex faktorer. https://lup.lub.lu.se/student-papers/record/4462217/file/4462447.pdf application/pdf 2564966 no 2014 swe Open source closed source mjukvara Technology and Engineering 4462217 2014-06-10T14:58:13+02:00 2014-06-17T15:14:50+02:00 2014-06-17T15:14:50+02:00

Utifrån det behovet har Content Management Systems (CMS) framkommit, som har som huvudsyfte att stödja och underlätta innehållshanteringen. Då implementering av ett CMS är ett relativt omfattande projekt, vill vi undersöka vad som leder till att organisationer lyckas med ett sådant projekt. Syftet är således att identifiera framgångsfaktorer som organisationer och leverantörer kan ha i åtanke vid åtagande av ett CMS-projekt. Under studiens gång togs ett ramverk fram för att strukturera resultatet och analysen, samt för att belysa de områden vi tror är viktiga i en implementering av ett CMS. Vår empiriska undersökning bestod av kvalitativa intervjuer med fyra företag som levererar CMS-lösningar, samt med en övrig informant som innehar stor kunskap inom ämnet. Den slutsats som framkom av undersökningen var att det finns ett flertal faktorer som ger en lyckad implementering av ett CMS, men samtliga kunde relateras till områdena processer, användare och planering. https://lup.lub.lu.se/student-papers/record/4462822/file/4462828.pdf application/pdf 1183884 LU/LTH access 2014 swe CMS implementering framgångsfaktorer innehållshantering organisation Technology and Engineering Business and Economics 4462822 2014-06-10T21:38:21+02:00 2014-06-17T15:14:58+02:00 2014-06-17T15:14:58+02:00

studentPublicationsM2 Simon Carlson author Fredrik Lindblom author Programmes in Helesingborg v1000317 department This rapport is a study in advance of a possible up and coming restoration of the old observatory in Lund. The rapport is based on the possibility that it will be restored to accommodate modern facilities and suit the needs and demands we have on a modern building regarding installations and accessibility. This rapport describes in detail how to transform and renovate the old observatory to house a modern operation. The rapport includes an excessive study and documentation on the current state of the building The observatory has been used as an observatory for about a hundred years which have led to many makeshift solutions and poor choices regarding material when it has been repaired. A number of suggestions on how to transform this building into a modern functioning one which conserves the unique qualities this magnificent building have been the result of this study. The main focus has been to rectify the poor restorations that have been undertaken previously which has in many ways damaged the buildings interiors as well as exterior. In addition to pure restoration work the restoration plans which has been the result of this study also includes two separate ways on how to improve on the use of energy and heating. The first suggestion focuses on keeping the building intact without altering the interior. The second one is more extensive and alters the interior more than the first but brings the building to a energy consumption level where it complies with the regulations regarding newly constructed buildings. Neither of the two suggestions do in any way change the exterior of the observatory as it is heavy regulated in accordance which it state as a listed historical building. In accordance with Swedish regulations energy consumption of both suggestions are declared in detail. Also the energy consumption in the observatory’s current state has been calculated. These calculations shows that the first suggestion lessens the energy used in the observatory with about 50 percent and suggestion two with about 80. The total cost for these renovations are estimated to be around 5 to 7 million SEK. Complementary to the two suggestions the rapport contains details of escape routes and accessibility for which suggestions on improvements in accordance with modern regulations are made. The cost of all suggestions are individually presented as a budget, this is to give the user to give the user the option of choosing from an array of methods which are suitable for the building. The main focus has been to keep the spirit of the building intact and to keep the exterior unaltered. It is important for the reader of this document to remember that the observatory in Lund is an historically important building with unique qualities. https://lup.lub.lu.se/student-papers/record/4462898/file/8961721.pdf application/pdf 5440799 no 2014 swe observatorium restaurering renovering energiberäkning tilläggsisolering tillgänglighetsanpassning helgo zettervall Technology and Engineering 4462898 2014-06-06T00:00:00+02:00 2018-10-18T10:28:38+02:00 2014-06-11T00:00:00+02:00

studentPublicationsM2 Markus Gustavsson author Programmes in Helesingborg v1000317 department This thesis is about ”BIM &quot; , it addresses the problems and risks associated with the introduction in Sweden and how the expression is misinterpreted. The work also includes how BIM should be used to achieve profitability and how the different operators relate to it.<br /> The Swedish construction industry is today exposed with big problems when it comes to productivity, efficiency, material waste and a variety of other factors. They are searching for solutions to these problems, and the answer to some of these might just be BIM.<br /> BIM is still a relatively new approach, where the concept is all about reuse and smart ways to manage information through various stages. This is then often visualized in one or a few 3D models, instead of traditional engineering where it is made up by many drawings, thereby contributing among other things to a greater understanding to those involved in the projects.<br /> The thesis is based on an analysis of the results, that have been obtained by a literature review and ten interviews with people from different stages and stakeholders in the industry, which have all in one way or another, been working with BIM . The result intends to create a greater understanding of this complex concept and a possibility to be used as a complement when using BIM, where it can give a hint on how a project should be profitable and how common mistakes can be avoided.<br /> After analyzing the information given by the work, the answers to the following questions are responded to in the conclusion:<br /> - What difficulties are there in introducing BIM in the rail project?<br /> - What benefits can be achieved through the use of BIM in the railway project and who will use them?<br /> - In what kind of rail projects is BIM profitable?<br /> If a greater understanding of what BIM is wished before the reading of this work, then the readers are advised to watch the video &quot;What is BIM ? &quot; Published by Trafikverket on Youtube, which runs through the basics of the concept, http://www.youtube.com/watch?v=6pjd6TYKd4o .<br /> Keywords: BIM, Machine Control, 3D modelling, Model, Railroad, level of detail, design https://lup.lub.lu.se/student-papers/record/4462902/file/8961722.pdf application/pdf 752076 no 2014 swe bim anläggningsmodell maskinstyrning 3d-modellering modell järnväg detaljeringsnivå projektering Technology and Engineering 4462902 2014-06-10T00:00:00+02:00 2018-10-18T10:28:40+02:00 2014-06-11T00:00:00+02:00

This type of construction is not usually built anymore, all because of new techniques that replaces this kind of large mass grain storages. The intention of the report is to analyze how an industrial building, shaped as a silo can be changed into residential blocks. The study is meant to describe how<br /> this can be done in a sustainable way by preserving as much as possible from the original construction. The reconstruction is analyzed from a technical angle and is based on the work of a student of architecture, Christoffer Justusson. The project he has made is then studied and analyzed to confirm if the project is<br /> technically possible and also what changes needs to be made in the construction. An important part of the report is meant to analyze if there is a possibility to<br /> cover the facade with climbing green plants. A number of problems forms the base of the report, such as, if it is possible to<br /> perform the transformation and how does the process along the way look like. To see how history has left its marks on the building is also an important observation. Even the study of a green facade has contributed with some questions, like if the idea even is possible in the area and how the plants affect the building and the people around it. Furthermore what plants can be used and how maintenance is done is also analyzed. By our own gathered knowledge and by consulting specialists in several<br /> domains and also by reading technical literature, necessary information has been collected for the report. The result of the report describes the importance in preserving this unique silo in the city of Malmö and how changing it into residential blocks amplifies the fact that it has an enormous contribution to the city&#39;s history. As a result of the work a conclusion can be made. That this kind of transformation takes an enormous amount of planning and preparatory work to create a successful result<br /> with sustainable technology. https://lup.lub.lu.se/student-papers/record/4462905/file/8961723.pdf application/pdf 8529916 no 2014 swe hållbarhet bevarande kulturhistorisk bostadssilo gröna fasader sustainability preservation culture-historical the residential silo green facades Technology and Engineering 4462905 2014-06-09T00:00:00+02:00 2018-10-18T10:28:42+02:00 2014-06-11T00:00:00+02:00

studentPublicationsM1 Marcus Lindén author 4463081 Jan Olhager supervisor Engineering Logistics v1000260 department Bakgrund: OF Ekeri är ett nationellt företag med kontor i Markaryd. De levererar och hyr ut ett stort utbud av olika typer av lastbilssläp som till exempel släpvagnar, påhängsvagnar och reservdelar. Nästan alla företag i dag har någon form av informationssystem, men många av dem är ineffektiva. OF Ekeri är medvetna om att deras sätt att hantera deras information inte är uppdaterad och därför de har bett om hjälp. Om det är möjligt att utnyttja deras informationssystem på ett effektivare sätt, kan det bidra med stora besparingar.<br /> <br /> Problem: Problemet i dag är att OF Ekeri inte utnyttjar sina informationssystem till sin maximala kapacitet vilket kostar pengar och leder i slutändan till mer arbete.<br /> <br /> Syfte: Syftet är att göra en grundlig analys av OF Ekeri´s informationshantering och informationsflöde samt möjliggöra och visa utförbara förbättringar.<br /> <br /> Metodik: I detta examensarbete har en induktiv metod använts. Först samlades OF Ekeri´s empiriska information in, och utifrån den har teorier samlats och analyser gjorts. Detta examensarbete har genomförts som en fallstudie. En grundlig förståelse för verksamheten skapades innan eventuella förbättringar skapades. Data har samlats in genom intervjuer, observationer och litteraturstudier. Under undersökningen har betoningen legat på att se till att tillförlitlig och giltig data har använts.<br /> <br /> Resultat: Förbättringar av de nuvarande informationssystemen kommer att resultera i mindre arbetstid, optimering av deras sätt att arbeta på OF Ekeri och stora besparingar. Vilket resultat man kommer uppnå beror på vilka implementationer OF Ekeri väljer att göra. De rekommenderade investeringarna har en rimlig investeringskostnad i förhållande till de fördelar som de genererar, en kort avkastning på investeringen och de kommer att förbättra sättet att arbeta på. De är också realistiska för OF Ekeri att genomföra med avseende på både kapital och tid.<br /> <br /> Slutsats: Att investera i ett större ERP system just nu är inte relevant för OF Ekeri. Ett ERP hade varit mer passande om OF Ekeri hade kontor på olika ställen, hade produktion av släpvagnar istället för att bara köpa dem och sälja dem vidare och om de hanterade större volymer av produkter och transporter. Informationssystemen LIME och Visma och deras förmåga att integrera med varandra och andra webbaserade system underlättar väldigt mycket, vilket gör de nuvarande systemen tillräckligt bra för OF Ekeri. Uppgraderingarna till deras nuvarande informationssystem kommer generera stora besparingar i förhållande till kostnaderna för genomförandet och de kommer ge bra resultat. Det kommer att vara viktigt för de anställda på OF Ekeri att lita på de nya möjliga implementeringarna för att få dem att nå bästa resultat Background: OF Ekeri is a national company with an office in Markaryd. They deliver and rent a wide selection of different types of truck trailers, semitrailers and spare parts. Today almost all companies have some kind of information system and many of them are inefficient. OF Ekeri is aware of that their way of managing their information is not up to date and therefore they have asked for help regarding if it is possible to manage their information systems more effectively which could contribute to savings.<br /> <br /> Problem: The problem today is that OF Ekeri does not fully utilizes their information systems which cost money and leads to more work in the end.<br /> <br /> Purpose: The purpose is to perform a thorough analysis of OF Ekeri´s information management and information flow and make possible and reasonable improvements.<br /> <br /> Methodology: In this master thesis the inductive approach has been used. First, OF Ekeri´s empirical information was gathered, and based on that, theories were collected and analyses were made. This master thesis has been conducted as a case study. A thorough understanding of the business was created before trying to improve it. Data has been gathered through interviews, observations and literature studies. During the research, emphasis has been on ensuring that reliable and valid data has been used.<br /> <br /> Results: Depending on which of the suggested implementations OF Ekeri chooses to do, the improvements of the current Information systems will result in variety of less work hours, optimized working method and major savings. The suggested investments have a reasonable investment cost relative to the benefits it will generate, a short Return of Investment (ROI) time and they will improve the way of working. They are also realistic for OF Ekeri to implement with regard to both capital and time.<br /> <br /> Conclusions: Investing in an ERP system right now is not relevant for OF Ekeri. An ERP system would have been more suitable if OF Ekeri had offices in different locations, had own production of trailers instead of buying them and selling them on and handled larger volume of products and transportations. The current information systems LIME and Visma and their ability to integrate with each other and other web-based systems simplifies a lot, which makes the current systems good enough for OF Ekeri. Upgrades of their current information systems will generate big savings relative to the implementation cost and generate good results. It will be important for the employees at OF Ekeri to be able to trust the new possible implementations for them to reach the best results. https://lup.lub.lu.se/student-papers/record/4463048/file/4463077.pdf application/pdf 956687 no 2014 eng Information System ERP (Enterprise Resource Planning) CRM (Customer Relationship Management) WMS (Warehouse Management System) FMIS (Financial Management Information System) Return of Investment (ROI) Technology and Engineering https://lup.lub.lu.se/student-papers/record/4463048/file/4463080.pdf application/pdf no 4463048 2014-06-11T10:55:33+02:00 2014-08-25T13:12:54+02:00 2014-08-25T13:12:54+02:00

Konsulterna<br /> arbetar i en central roll mellan programvaruleverantör och slutkund<br /> för att ta fram BI-lösningar. Denna roll är viktig att diskutera för att<br /> förstå varför kunden ej kan gå direkt till leverantören. I denna studie<br /> har vi undersökt hur konsultation ser ut inom BI för att förstå hur<br /> konsulter arbetar när de tar fram BI-lösningar. Den empiriska<br /> undersökningen har gjorts i form av intervjuer med konsultbolag som<br /> arbetar med att ta fram lösningar inom BI. Resultatet är att det arbete<br /> som konsulten utför är mycket kundnära och rollen handlar om att<br /> vinna förtroende för både partners och slutkund. I val av partners är<br /> det marknaden som bestämmer och det sker kontinuerlig avstämning<br /> med partners för att se till att affärsmålen uppnås.

studentPublicationsM1 Sara Nordlund author 4463117 Jan Olhager supervisor Engineering Logistics v1000260 department The purpose of this project is to find out if it will be beneficial to implement Multi-Echelon Optimisation(MEO) at Scania Parts Logistics (SL). SL is the department at Scania that is responsible for the spare parts distribution. The IT-system used for planning at SL is currently being replaced. Even though the new system, Spare Parts Management (SPM), can perform MEO it was decided not to use it during the initial roll out. SL however wants to know if they should implement MEO in the future.<br /> <br /> The project is performed with a deductive approach; the aim is to validate how the theory works in practice. The intention was to prove that MEO will be beneficial for SL to use by comparing the three different scenarios:<br /> 1. The old planning system<br /> 2. The new planning system, SPM, with standard settings<br /> 3. SPM with MEO activated<br /> For scenario 1 existing data was gathered from different sources at SL. This scenario was included to be able to validate the outcomes from the new system; since it was the first time anyone at Scania used SPM. For scenario 2 and 3, data regarding the spare parts was gathered and inserted into SPM. SPM was then run, in order to receive results that could be used for comparison.<br /> <br /> It was not possible to analyse the entire assortment, which consists of more than 100 000 parts, in the scope of this project. Instead a group of parts that could represent the complete assortment was chosen. SL had divided the assortment into different segments, according to an ABC-classification based on part cost and part demand. These segments were used to find the parts to analyse: a few parts from each segment, about 50 parts in total.<br /> <br /> The first analysis compared scenario 1 and 2, in order to see that SPM generated realistic results. It was quickly found that it did not; after performing a data validation, several parameters and settings needed to be adjusted in order to get accurate results. The old planning system has many limitations and uses quite simple methods to calculate forecasts and safety stock. With the new planning system, the expectations were to get more accurate results. Findings showed that the change in forecasts and safety stock levels differed from part to part: the levels both increased and decreased.<br /> <br /> Similar findings where made when comparing scenarios 2 and 3, the difference varied highly between parts. With such a high variation of results, it was not possible to state any conclusions based on these numbers alone. However, with MEO the average safety stock levels at Scania Parts Center (SPC), the central warehouse in Belgium, decreased by about 3%. At the seven Regional Warehouses (RW’s) located around Europe, several parts were removed from stock.<br /> <br /> Average inventory levels were compared between scenario 1 and 3. It was shown that the average inventory levels at SPC decreased by 25%, while at the RW’s the levels increased. This kind of result is also supported by the theory of MEO.<br /> <br /> The RW’s only deliver emergency orders, orders that should be delivered within 24 hours. All orders to refill stock are delivered straight from the central warehouse, SPC. The theory of MEO however, is based on regional warehouses supplying all types of orders. Therefore there is a risk of using MEO at the regional warehouses because the effects of MEO at such installations are not known. SL’s intention is to soon include a larger part of the distribution system in SPM. If this was to happen, the effects of using MEO will likely become greater.<br /> <br /> The conclusion was that further analysis is needed before deciding whether to implement MEO. The initial focus should be on making the standard version of SPM work as desired. When that is achieved, further evaluation of MEO can be carried out. Firstly, the entire assortment should be analysed in order to get figures that can be trusted. Alternatively, a better segmentation should be done to find more general parts to represent the assortment. Secondly, SL needs to consider if the RW’s should be included in the scope of MEO. If not, the recommendation will be to wait with implementing MEO until more nodes are included in SPM. Then the benefits of using MEO will likely exceed the cost of resources required to implement it. Syftet med detta projekt är att ta reda på om det är fördelaktigt för Scania Parts Logistics (SL) att implementera flernivåoptimering, så kallad multi-echelon optimisation (MEO). SL är den avdelning på Scania som är ansvarig för distributionen av reservdelar. För tillfället håller det IT-stöd som används för planering på att bytas ut på SL och i det nya systemet, Service Parts Management (SPM), är det möjligt att aktivera en funktion som utför flernivåoptimering. Till en början har SL valt att inte implementera denna funktion, däremot vill de veta om de borde implementera den i framtiden.<br /> <br /> Projektet är genomfört med en deduktiv ansats, vilket innebär att teorin kring flernivåoptimering kommer att testas genom att simulera verkligheten. Målet är att visa att det är mest fördelaktigt för SL att använda flernivåoptimerings-funktionen, genom att testa tre scenarion:<br /> 1. Det gamla planeringssystemet<br /> 2. Det nya planeringssystemet, SPM, med standardinställningar<br /> 3. Det nya planeringssystemet, SPM, med flernivåoptimerings-funktionen aktiverad<br /> <br /> Scenario 2 jämfördes med scenario 1 för att verifiera att resultaten från det nya planeringssystemet var godtagbara. Det konstaterades snabbt att så inte var fallet: flera parametrar och inställningar behövde justeras innan resultaten blev korrekta.<br /> <br /> Då det inte var möjligt att analysera alla de över 100 000 reservdelar som finns i lager i distributionssystemet, valdes en grupp av artiklar ut som kunde representera det kompletta sortimentet. SL hade en segmentering av sortimentet, baserad på en ABC-klassificering där artiklarna var klassade efter deras kostnad och efterfrågan. Denna segmentering användes som bas för att välja ut de cirka 50 artiklar som analyserades.<br /> <br /> Resultaten visade att hur mycket säkerhetslagernivåerna och de beräknade prognoserna ändrades, skiljde sig från artikel till artikel. Då det nya systemet har mer avancerade räknemetoder, var förväntningen att prognoser och säkerhetslagernivåer skulle stämma bättre överens med verkligheten. Det skulle kunna förklara varför skillnaderna både ökade och minskade. Liknande upptäcker gjordes när scenario 2 och 3 jämfördes: skillnaderna i hur lagernivåerna ändrades skiljde sig mycket åt mellan olika reservdelar. Det var därför väldigt svårt att dra slutsatser om hur skillnaderna hade blivit för det totala sortimentet och vilket scenario som faktiskt gav bäst resultat.<br /> <br /> Då flernivåoptimerings-funktionen var aktiverad i SPM, sjönk antalet artiklar som skulle lagerhållas på de sju regionala lager som finns i Europa. Samtidigt visades att medellagernivån på dessa platser istället ökade. Slutsatsen var att genom att använda flernivåoptimering så skulle ett mindre antal artiklar hållas på regionala lager, men istället skulle fler enheter av resterande artiklar finnas tillgängliga på lagren.<br /> <br /> På centrallagret i Belgien, Scania Parts Center (SPC), skulle medellagernivån sänkas med 25 %, jämfört med nuvarande nivåer. Säkerhetslagernivåerna sänktes ytterligare med 3 % när flernivåoptimering var aktiverat, jämfört med endast standardversionen av SPM. Dessa siffror är inte tillräckliga för att dra en klar slutsats om ifall flernivåoptimerings-funktionen bör aktiveras, men de visar åt vilket håll det verkar luta.<br /> <br /> De regionala lager som finns i SL’s distributionssystem hanterar endast akuta order, då reservdelar måste levereras inom 24 timmar. De vanligaste orderna, de som görs för att fylla på i lagren, skickas alltid direkt från centrallagret SPC. Teorin kring flernivåoptimering är baserad på lager som hanterar alla typer av order, det finns därför en risk med att optimera regionallager, då det är oklart vilken effekt flernivåoptimeringen skulle få. I framtiden planerar SL att ta in en större del av distributionssystemet i SPM, då skulle effekterna av flernivåoptimering kunna få en mycket större omfattning.<br /> <br /> Slutsatserna är att fler analyser är nödvändiga för att kunna bestämma om flernivåoptimering ska implementeras eller inte. För att få tydliga resultat bör hela sortimentet tas med i analyserna, alternativt krävs en bättre segmentering och ett noggrannare urval av artiklar. SL bör också fundera över om de anser att regionala lager bör vara med i optimeringen. Om de lämnas utanför, är rekommendationen att vänta med att använda flernivåoptimering tills fler noder installeras i SPM. Då är det mer troligt att fördelarna med att implementera flernivåoptimering skulle överstiga riskerna. 2014 eng Technology and Engineering 4463093 2014-06-11T11:31:47+02:00 2014-08-26T13:05:43+02:00 2014-08-25T13:10:44+02:00

Furthermore it is to explore the recognition level<br /> and business impact of these propositions.<br /> <br /> Methodology: The work process consisted of an initial explorative phase where a theoretical framework was created based on literature research. Founding on that the maturity model was developed, and then further tested in a survey. The survey also examined the recognition level of the propositions. To explore the business impact of the propositions three in depth interviews were held.<br /> <br /> Conclusion: The main conclusions in the project are that the eight examined propositions are common challenges among large Scandinavian companies. The developed maturity model covers these challenges and can be used by organizations to see where they are at in their maturity curve and what the next step in the maturity process is. The higher the BI maturity is, the less recognized the propositions are. The recognition level of propositions and the BI maturity impact the business success, and the BI maturity among large Scandinavian companies is somewhat moderate. Other conclusions are that a well functioning BI environment is essential for any large organization since it enables the achieving of strategic goals such as efficient and effective processes. However, efficientBI-­processes and a functioning IT landscape can be difficult to establish, especially for large companies. There are extensive amounts of data to<br /> process, the implementation costs are high, and the needed change management resources are often overlooked. https://lup.lub.lu.se/student-papers/record/4463173/file/4519568.pdf application/pdf 2702091 no 2014 eng Business Intelligence Maturity Model Operational Challenges Business Impact Value Creation Technology and Engineering https://lup.lub.lu.se/student-papers/record/4463173/file/4463189.pdf application/pdf no 4463173 2014-06-11T12:35:03+02:00 2014-08-25T13:13:46+02:00 2014-08-25T13:13:46+02:00

studentPublicationsM1 Rickard Karlsson author 4463263 Erik Flink author 4463264 Dr Kostas Selviaridis supervisor Engineering Logistics v1000260 department Problem Discussion: The oil and gas sector is not very mature in terms of supply chain management. The chosen case company, Maersk Drilling (MD), has problems with a split IT-­landscape with poor data quality. It has caused problems with inefficient and complex processes with much communication required, parallel information and more. Within procurement it translates to problems in spend management and time wasted with tracing orders. The ERP system plays an important role in supporting information sharing, cross-­functional ways of working and a better overview. By introducing a new ERP system some major changes are expected within supply chain and processes will have to be changed. The ERP project is significant hence there are many stakeholders who may perceive the potential challenges differently.<br /> <br /> Purpose: The purpose of the study is to dig deeper into how the change with a new ERP system will affect the procurement and supply chain processes at Maersk Drilling. The changes bring challenges as well. The study gives a deep understanding of the perceptions of challenges from the different actors. It is important in order to see if everyone works towards the same goal.<br /> <br /> Methodology: This thesis is a qualitative single case study. The theory was gathered prior to a pre-­study that was made at the company in order to grasp the problem and come up with the research questions. Thirteen interviews were made and archival data from the company was collected. This provided several sources of data and triangulation was possible. The data collection was then matched with the theory in order to secure that the theory would cover the specific research questions. After that the analysis was conducted where empirical data was compared with the theory. Finally the conclusions from the whole study were drawn. <br /> <br /> Frame of Reference: The reasoning when setting the theoretical framework was that the ERP project is the start of a radical change in the way of working at MD. Many processes are redesigned or improved. The whole study is within the procurement and supply chain area and with this reasoning we then set up the structure for the theoretical framework containing the three areas; Procurement and SCM, Processes, and ERP. In the latter change management plays an important role since the new system means a major change in the way of working for many persons at the case company.<br /> <br /> Conclusions: ERP has been an enabler for the changes and the new processes will become more streamlined, standardized and cross-­functional. Increased information sharing will help MD to work more efficient and additional/improved data will give MD an enhanced overview in form of management reporting. The new ERP system was not affecting the level of centralization very much, since the structure of decisions in procurement was not changed. The challenges in implementing these changes have been communicated well between the stakeholders and the view of the challenges is overall unified. Master data was perceived as the biggest challenge, most likely since the project is in the establish phase and that MD has a starting point with very poor data. The data quality is of high importance when migrating data to the new system. MD furthermore needs to look closely at how the offshore personnel perceive the project and how they will meet the changes. The vision was also containing technical and management jargons, which makes it less understandable. Today they use good information and many channels but MD needs to make sure that the communication reaches the end users to achieve buy-­in. Problemdiskussion: Sektorn för olja och gas är inte särskilt mogen när det gäller kunskapen om försörjningskedjor. Det valda företaget för fallstudien, Maersk Drilling (MD), har problem med ett splittrat IT-­landskap och dålig datakvalitet. Det har orsakat problem med ineffektiva och komplexa processer där det krävs onödig kommunikation, parallell inmatning av data, etc. Inom upphandlingar och inköp leder det till problem med förståelsen för hur pengarna spenderas och tid slösas bort med att spåra order. Affärssystemet(ERP) spelar en viktig roll för att stödja informationsutbyte, tvärfunktionella arbetssätt och ge en bättre överblick. Genom att införa ett nytt affärssystem väntas stora förändringar inom leveranskedjan och processer kommer att behöva ändras. ERP-­projektet är så pass omfattande och de olika aktörerna kan därför uppfatta de potentiella utmaningarna på olika sätt.<br /> <br /> Syfte: Syftet med studien är att gräva djupare i hur förändringen med ett nytt ERP-­system kommer att påverka inköps-­ och logistikprocesser hos Maersk. Eftersom ERP-­projektet är stort med många personer inblandade, kommer det att innebära förändringar i organisationen och i de roller och ansvarsområden som finns. Det är viktigt att få en djup förståelse för de olika uppfattningarna i projektet när det gäller utmaningarna, för att se om alla arbetar mot samma mål och har samma uppfattning.<br /> <br /> Metod: Uppsatsen är en kvalitativ fallstudie. En del teori studerades inför en förstudie som gjordes på företaget för att förstå problemet och komma på de forskningsfrågor som uppsatsen skulle bygga på. 13 intervjuer gjordes och arkivdata från företaget samlades in. Detta gav forskarna flera datakällor och triangulering var möjligt. Datainsamlingen matchades sedan med teorin för att säkerställa att teorin skulle täcka de specifika forskningsfrågorna. I analysen jämfördes empirisk data med teorin och slutligen så drogs slutsatserna från hela studien.<br /> <br /> Referensram: Resonemanget när den teoretiska ramen framställdes var att ERP-­projektet är början på en radikal förändring i sättet att arbeta på MD. Många processer kommer göras om eller förbättras. Hela studien är inom inköps-­ och försörjningskedje-­ området och med detta resonemang skapades sedan en struktur för det teoretiska ramverk som innehåller de tre områdena; försörjningskedjor och inköp, processutveckling och affärssystem (ERP). I den sistnämna inkluderas även förändringsarbete vilket spelar en viktig roll då det nya systemet innebär en stor förändring i sättet att arbeta för många personer på fall företaget.<br /> <br /> Slutsats: Affärssystemet har varit en möjliggörare för förändringarna och de nya processerna kommer att bli mer effektiva, standardiserade och tvärfunktionella. Ökad informationsdelning kommer att hjälpa MD att arbeta mer effektivt och utökad/förbättrad data ger MD en överblick i form av ledningsrapportering. Det nya affärssystemet påverkar inte graden av centralisering nämnvärt eftersom strukturen av besluten i inköpsprocessen inte kommer förändras. Utmaningarna med att genomföra dessa förändringar har kommunicerats väl mellan de berörda parterna. Master data uppfattades som den största utmaningen, troligen eftersom projektet är i etableringsfasen och MD har en utgångspunkt med dålig data. Datakvaliteten är även av stor betydelse vid förflyttning av data till det nya systemet. MD behöver dessutom titta närmare på hur offshore personalen uppfattar projektet och hur de kommer att bemöta förändringarna. Visionen innehåller teknisk och administrativ jargong, vilket gör det mindre begripligt, och den behöver utvecklas. Idag använder många informationskanaler, men MD måste se till att kommunikationen når slutanvändarna för att få dem att anamma det nya systemet. https://lup.lub.lu.se/student-papers/record/4463194/file/4464102.pdf application/pdf 5775885 no 2014 eng Supply Chain Management Procurement Processes Change Management ERP Perceived challenges Oil and Gas Försörjningskedjor Inköp Processer Förändringsarbete Technology and Engineering https://lup.lub.lu.se/student-papers/record/4463194/file/4464108.pdf application/pdf no 4463194 2014-06-11T12:55:35+02:00 2014-08-25T13:14:39+02:00 2014-08-25T13:14:39+02:00

Vad som inte är lika känt är vilken roll IT har i sammanhanget. År 2010 stod IT för cirka 2 % av de totala utsläppen av växthusgaser, vilket är en siffra i nivå med flygindustrins utsläpp. Den påtagliga inverkan som IT har visat sig ha på vår miljö har gett upphov till ökade insatser på området. Begreppet grön IT blir allt vanligare och certifieringar som Energi Star förekommer idag på många av våra datorer och skärmar. Då företags verksamheter idag ofta är beroende av IT-stödda informationssystem är grön IT inom företag ett viktigt ämne. Vad som driver företagen till ett arbete med grön IT är tidigare studerat i länder med stor potential till förbättring inom hållbarhetsarbetet i stort. Vi ställde oss därför frågan hur situationen ser ut hos företag i Sverige, som är ett land i framkant inom arbetet mot ett hållbart samhälle. För att besvara frågan vände vi oss till befintlig litteratur i ämnet och använde det som grund för att utforma ett ramverk menat att förklara vad som motiverar företag till att arbeta med grön IT och hur ett sådant arbete kan indikeras i verksamheten. Vi genomförde intervjuer med sex svenska företag för att komplettera befintlig litteratur. Vi fann att arbete med grön IT indikeras på olika sätt men att det finns en kärnverksamhet kring energikonsumtion i datorhallar. Utifrån detta fördjupas arbetet på olika sätt med analyser som ser till strömhantering. Resultaten visar även att den största motivationsfaktorn bland företagen är miljöansvar. Yttre påtryckningar såg ingen av företagen i studien som en motivation till arbetet med grön IT, vilket skiljer sig från tidigare forskning. https://lup.lub.lu.se/student-papers/record/4463604/file/4463611.pdf application/pdf 949651 no 2014 swe grön IT motivationsfaktorer grön IKT Technology and Engineering 4463604 2014-06-11T19:51:08+02:00 2014-06-17T15:15:07+02:00 2014-06-17T15:15:07+02:00

Problemet för denna uppsats grundar sig i att teorin undviker att tillhandahålla specifik information vid ett verklighetsbaserat genomförande. Information som exempelvis definition av övriga intressenter och deras ansvarsområde framgår inte. Vidare påvisas en tydlig avsaknad av information gällande hur Sprint Review skall genomföras, vilken information det material som exempelvis omvärldsanalysen skall hantera samt om eventuella prioriteringsskillnader förekommer mellan aktörer. Utifrån teorin identifierades fyra huvudområden som ligger till grund för genomförandet av detta event, nämligen Kunskap, Kommunikation, Reflektion och Lärande. Syftet med studien har varit att kartlägga genomförandet av Sprint Review. Vidare har även de medverkande aktörernas prioriteringsgrad undersökts utifrån projektorganisationen synvinkel. För att undersöka ovannämnda aspekter etablerades ett ramverk som identifierar utvalda teman. Ramverket tillämpades i den empiriska undersökning som genomfördes genom semi-strukturerade intervjuer. Informanterna innehar, eller har innehaft, positionen som SCRUM Master i mjukvaruutvecklingsprojekt. Uppsatsens primära slutsatser är att kundorganisationen prioriterar Sprint Review påtagligt lägre än projektorganisationen utifrån projektorganisationens perspektiv. Prioriteringsgraden är starkt knuten till kunskap och därmed förståelsen för Sprint Review och det agila genomförandet. https://lup.lub.lu.se/student-papers/record/4463632/file/4463636.pdf application/pdf 1642029 no 2014 swe Agil projektledningsmetod SCRUM Sprint Review Kartläggning Prioriteringsgrad Technology and Engineering 4463632 2014-06-11T20:37:04+02:00 2014-06-17T15:17:24+02:00 2014-06-17T15:17:24+02:00

studentPublicationsM2 Sandra Anderberg author Johanna Strand author Peter Johansson supervisor Civil Engineering - Architecture (BSc) LURS00008 department Division of Building Materials v1000221 department Byggsektorn står för ca 40% av Sveriges årliga totala energiförbrukning. För att minska denna siffra är ett alternativ är att bygga hus som förbrukar mindre energi. Exempel på en sådan hustyp är passivhus och därför är dessa intressanta att studera närmare med avseende på tillverkningsenergi. I rapporten har tre passivhus (Emrahuset, Passivhuset och Ytonghuset) i olika utföranden jämförts tillsammans med ett traditionellt hus (Konventionella huset). De fyra husen har jämförts med varandra med avseende på tre parametrar: årlig specifik energianvändning, tillverkningsenergi och livslängd. Olika konstruktionslösningar har utformats för de fyra husen, med olika material och dimensioner för att kunna undersöka materialets inverkan på energiförbrukningen totalt sett. Arbetet har genomförts med hjälp av beräkning av årlig specifik energianvändning i datorprogrammet Isover Energi 3, samt insamling av data angående tillverkningsenergi. Tillverkningsenergin har beräknats specifikt för varje hus med avseende på ingående material och dimensioner. Konventionella huset, konstruerat på BBR:s strängaste krav på U-värde, fick en årlig specifik energianvändning på 68 kWh/m2, vilket är 25% mindre än BBR:s krav på specifik energianvändning. De tre passivhusklassificerade husen, konstruerade med krav enligt FEBY 12, de fick en årlig specifik energianvändning på 25 kWh/m2. Emrahuset, uppbyggt av cellplast och betong, fick lägst tillverkningsenergi (21 945 kWh). Ytonghuset, bestående av enbart lättbetong, fick den högsta tillverkningsenergin (59 750 kWh). Tegel och betong är de material med längst livslängd medan tejp och foam för tätning är de material med kortast livslängd. Alla husen hade för- och nackdelar men då alla de tre utvärderade parametrarna vägs samman blir resultaten bäst för Ytonghuset. Detta eftersom den förväntade livslängden överstiger ställda krav, oorganiska material används vilket resulterar i minimal risk för fuktproblem, att använda få material i konstruktionen föredras (färre genomföringar, färre köldbryggor) och ingen plastfolie som riskerar att mista sin lufttätande funktion om den förstörs. Sammanfattningsvis är inte en låg tillverkningsenergi den långsiktigt bästa investeringen. Viktigt är att beakta materialens beständighet och livslängd, det kan nämligen bli olönsamt att tvingas byta ut konstruktionsdelar som mist sin funktion jämfört med att investera i material med längre livslängd men med en något mer energikrävande tillverkningsprocess. https://lup.lub.lu.se/student-papers/record/4463716/file/8961724.pdf application/pdf 7712713 no 2014 swe passivhus tillverkningsenergi specifik energianvändning u-värde mineralull ytong cellplast eps årlig specifik energianvändning byggvarudeklaration bbr livslängd Technology and Engineering Detta examensarbete är utfört vid Avd Byggnadsmaterial, Lunds Tekniska Högskola 4463716 2014-06-11T00:00:00+02:00 2018-10-18T10:28:44+02:00 2014-06-12T00:00:00+02:00

Det har mynnat ut i flera olika åtgärder, bland annat- för Sverige- en helt ny spårväxelstandard kallad 60E. Examensarbetet är framförallt en jämförelsestudie mellan de tre vanligast förekommande äldre växeltyperna SJ50, BV50, UIC60 och den nya spårväxelstandarden 60E. Nyheter som rälslutning, nytt växeldriv och bredare spårvidd i 60E ställs mot de gamla växlarnas motsvarigheter och analyseras utifrån hur de har förbättrats. Arbetet beskriver också principiell uppbyggnad och funktion av en växel ur en anläggnings perspektiv. Rapporten belyser skillnader och nyheter i en spårväxel som förbättrar drift och funktion i anläggningen. Arbetet har utförts på ÅF Infrastructure, Helsingborg. Arbetet utgår från följande frågeställningar.<br /> • Kommer problematiken med is och snö i växlarna att minska vid användning av 60E?<br /> • Vad händer med växlar som byts ut i förtid?<br /> • Blir underhållet av 60E-växlarna enklare än av äldre modeller?<br /> • Kommer de totala kostnaderna kring växlar att minska? Datainsamlingen har dels gjorts genom en litteraturstudie av framförallt föreskrifter och standarder från Trafikverkets databaser och dels genom intervjuer av representanter från de inblandade parterna beställare, konsulter, leverantörer och sakkunniga utomstående. Det har resulterat i framförallt ban- och signaltekniska slutsatser kring hur förbättringarna för spårväxlarna påverkar fordon och bana. Förbättringarna leder till bättre tåggång, färre snökänsliga platser, jämnare slitage, högre hastigheter och högre axellaster. Skillnaderna mellan gamla växelserier och den nya är påtagliga vilket redovisas i arbetet. Det är lätt att förstå hur tankegången sett ut då denna växelserie tagits fram och vad som gjorts för att undvika slitage, driftfel och höga livscykelkostnader. Arbetet behandlar inte hur myndigheter och politiker skött järnvägen eller vad politiska beslut inneburit för anläggningen. Samhällsekonomiska aspekter behandlas inte heller.

En för branschen obeprövad entreprenadform har snabbt introducerats på marknaden och medfört möjligheter men även problem. Rapporten behandlar de största och mest betydande skillnaderna i förfrågningsunderlaget och allmänna bestämmelser mellan totalentreprenad och utförandeentreprenad. I en studie belyser vi även hur parternas inställning är till totalentreprenad och var effektivisering av entreprenadformen behövs för att bättre anpassas till en styrd järnvägsbransch. Efter litteraturstudier bildades en uppfattning om hur totalentreprenad fungerar och vilka för- och nackdelar som finns med totalentreprenad jämfört med utförandeentreprenad. Genom intervjuer av personer med erfarenhet av totalentreprenader kunde vi ta del av branschens syn på entreprenadformen.<br /> För att förstå svårigheterna med funktionsbeskrivningar har rapporten även innefattat praktisk upprättande av funktionsbeskrivningar. Järnvägsbranschens regelverk och rutiner är i dagsläget inte anpassade för ett effektivt användande av totalentreprenad. En viktig del är utvecklingen av funktionskrav vid uppförandet av funktionsbeskrivningar vid järnvägsprojekt. Vidare är framtagandet av kontrollmetoder som blir praxis för branschen av det yttersta avgörande för användandet av funktioner ska fungera. Kontrollmetoder som inte bara kontrollerar funktioner efter entreprenadtiden utan under hela järnvägens livslängd.

studentPublicationsM2 Ida Kellokoski Adamsson author Programmes in Helesingborg v1000317 department Abstract Today large amounts of macadam are being delivered for the production of asphalt. One of the requirements of the material that´s being used is the adhesion. The adhesion is essential for the performance of the coating. It minimizes the risk of stone chips and makes the construction of the pavement stronger etc. Several studies have been made using the Roller bottle method. The results show that it is not enough to produce asphalt by only using bitumen and macadam, an adhesive is also required. Some of the adhesive materials that are considered to be the most suitable for the manufacture today are lime, cement and Wetfix I. The roller bottle method basically means that homogenous aggregate is being mixed with bitumen. In this study, adhesive will be in the mix to see if the results are affected in either a positive or a negative way. When the stones have been covered with bitumen and the adhesive they will be stored overnight at room temperature, then they will be placed in specially designed glass bottles filled with distilled water. The bottles will then be rolled on a roller table and will be evaluated regarding the stone coverage during different times. Three different adhesives will be evaluated in this study and aggregates from two different locations will be used. The aim of the study is to examine the adherence of various binders. The study will also examine, but only thoroughly, if the adherence varies depending on the aggregates qualities of the stones. The method involves taking photographs of the aggregate with and without adhesive materials at the different times of evaluation. On each occasion, several images will be taken of the aggregate. The images will be named for each material and occasion for easy identification of the images in the image editing software. The software is developed in Matlab environment, which is a commercially available computing language. The system for estimating the coverage of the bitumen consists of multiple steps. These steps are mentions below item 2.7.2 Steg för steg bildanalys. The results of the survey show that none of the evaluated adhesives yielded any positive results. For an adhesive to be useful it requires the coverage to be at least 70 % at the last check. The adhesive that were used showed different results depending on what aggregate was being covered. Keywords: Ocular assessment, adhesion, image analysis and coverage. https://lup.lub.lu.se/student-papers/record/4463728/file/8961727.pdf application/pdf 4690942 no 2014 swe rullflaska okulär bedömning vidhäftningsförmåga bildanalys och täckningsgrad Technology and Engineering 4463728 2014-06-11T00:00:00+02:00 2018-10-18T10:28:49+02:00 2014-06-12T00:00:00+02:00

But unfortunately, batteries are associated with short lifetime. By introducing Electrochemical Double-Layer Capacitors (EDLCs) as an alternative power source, the lifetime of the backup energy source can be significantly increased.<br /> <br /> The lifetime is dependent on two predominant factors; temperature and voltage. To evaluate the aging behavior of EDLCs, accelerated lifetime tests where performed. The measurements were carried out on capacitors from two different manufacturers (Cooper Industries and Maxwell Technologies). The results were then used for lifetime estimations.<br /> <br /> To accomplish an increased lifetime, a control system is suggested which monitors the capacitance and controls the applied voltage i.e. ptimizing the amount of stored energy. A complete power back up system with EDLCs as power source and an associated control system, was built and simulated in Simulink. Furthermore, an electrical hardware prototype was implemented to create a proof-of-concept. It is found that the lifetime can be significantly increased when controlling the applied voltage, since the voltage can be held as low as possible at all time. https://lup.lub.lu.se/student-papers/record/4464268/file/4464293.pdf application/pdf 30942634 no 2014 eng Supercapacitor Ultracapacitor Electrochemical Double-Layer Capacitor Energy Storage Power Source MATLAB Simulink Embedded Systems Aging Lifetime Estimation Voltage Control Control System.

studentPublicationsH1 Jens Månsson author Peter Gärdenfors supervisor Cognitive Science v1000050 department A model of the human stereopsis mechanism is presented. As foundation for the model lies a number of ideas that has arisen from redefining the correspondence problem. Instead of establishing potential matches by the detection and matching of some set of ?predefined? features, e.g. edges (zero-crossings) or bars (peaks/throughs), matches are sought by comparing the overall configuration of contrast within delimited regions of the two images. The main disambiguating<br /> <br /> power of the model is provided by combining the results of the matchings from a number of independent channels of<br /> <br /> different coarseness (in regard to the resolution of the contrast information). The idea is that the information in the coarser channels can be used to restrict the domain of potential matches, to be considered, within the finer channels. Important for this assumption is the concept of figural continuity. To further reduce the set of potential matches, the model relies on the constraint of uniqueness. A computer implementation of the model is presented, which from the input consisting of a stereogram, produces a representation of the binocular disparity present within the stereogram. A number of results obtained from this computer implementation are also presented and discussed. https://lup.lub.lu.se/student-papers/record/1333297/file/1333298.pdf application/pdf 508828 no 1997 eng Artificial intelligens stereopsis correspondence problem figural continuity Artificiell intelligens Technology and Engineering 1333297 2005-09-13T00:00:00+02:00 2009-04-20T11:19:18+02:00 1997-01-01T00:00:00+01:00

studentPublicationsH2 Goncalo Ferreira Cardoso author Charlotta Borell Lövstedt supervisor Division of Water Resources Engineering v1000225 department Vegetation is known to have different effects in shallow water environments, including changes in hydrodynamics. This often creates the need to include vegetation in large scale hydrodynamic models, which nowadays can already be achieved using some software packages available in the market. This work, however, had the purpose to test simple methods to simulate vegetation in hydrodynamic models without having the need to use vegetation specific software.<br /> <br /> Method: The tests were done using the MIKE 21 hydrodynamic module, developed by DHI Software, and two simple models were tested under different wind conditions. One of them simulated submerged vegetation by reducing the bottom depth as well as increasing the flow resistance values, while the other one, used to simulate emerged vegetation, consisted only of a significant increase in the flow resistance. In order to validate the models and the results obtained some field measurements were made in a local shallow lake, Krankesjön, and it was possible to see that the emerged vegetation used was plausible and also a good approximation, which didn?t clearly happen with the emerged model. The current speed values obtained by the modeling were consistent with the values measured in the lake, always in the order of greatness of a few centimeters per second.<br /> <br /> Results: The results obtained by the numeric modeling showed evident decreasing in the current speed values after introducing the vegetation models, along in some cases with changes in the preferential flow paths.<br /> <br /> Conclusion: As an overall conclusion of the project, the submerged vegetation model showed to potentially be a good approximation to study hydrodynamics in shallow lake environments, even if used only as a preliminary study, while the emerged model didn?t prove to be so reliable. Some improvements and further tests are suggested to both models, in particular to the one for emerged vegetation, such as altering the wind friction values in the water surface over the areas with emerged vegetation to better approximate the real phenomenon.<br /> <br /> (examensarbetet är utfört vid avd.

studentPublicationsH3 Evelina Karlsson author Karolina Persson author Associate professor Rolf Larsson supervisor Division of Water Resources Engineering v1000225 department Bakgrund: De centrala delarna av Vietnam har en årlig nederbörd på 4000 mm/år och det är vanligt med hastigt uppkomna översvämmningar (s.k. flash floods) här. Flash floods är plötsliga översvämmningar med ett högt flöde producerade av kraftiga regn. De sker oftast under natten och ger ofta upphov till jordskred. År 1999 skedde det en stor översvämning som spred sig 200 km längs kusten och dödade över 700 människor. Ett av områdena som drabbades var avrinningsområdet Tuy Loan. Det består av höga berg med branta sidor vilket gör det sårbart för flash floods. I avrinningsområdet har hydrometeorologiska mätningar skett under oktober och november 2003.<br /> <br /> Syfte: Huvudsyftet med studien är att öka förståelsen för de hydrologiska funktionerna i avrinningsområdet med betoning på flash floods.<br /> <br /> Metoder: För att analysera de hydrologiska processena i området analyserades vattenbalansen, respons tid och hydrografen. För att simulera flash floods användes enhetshydrografen och en avrinnigsmodell framtagen för flash floods (HRCmodellen). För att undersöka om det fanns ett mönster i hur det regnade gjordes en korrelationsanalys mellan stationerna i Tuy Loan och Thu Bon.<br /> <br /> Slutsatser: Svårigheterna med att förutse en flash flood gör att det är komplicerat att konstruera ett varningsystem. För att göra bättre prognoser behövs att en mer noggrann undersökning genomförs. Detta kan göras genom att analysera regnvärdena noggrannare genom att till exempel undersöka deras ursprung och rörelsemönster innan de når avrinningsområdet. En bättre förståelsen av avrinningsområdets funktioner skulle också uppnås genom att göra en geologisk undersökning av området. Det hade även varit önskvärt att genomföra mätningar under flera regnperioder i området för att få flera höga flöden att arbeta med. Detta hade kunnat förbättra funktionerna i modellerna som använts. Resultatet från denna rapport är inte tillräckliga för att kunna konstruera ett varningsystem.<br /> <br /> (examensarbetet är utfört vid avd.

studentPublicationsH3 Oskar Ljungqvist author Ylva Schwinn author Jes la Cour Jansen supervisor Professor Kenneth M Persson supervisor Division of Water Resources Engineering v1000225 department Ämne för detta examensarbete valdes efter en förfrågan från UNICEF att bistå dem att utvärdera ett mobilt system för dricksvattenproduktion. Sedan juni 2003 har EmWat 4000-systemet använts i Etiopien i områden med vattenbrist. För att försäkra sig om att systemet fungerar effektivt och att det producerade vattnet är av tillräckligt hög kvalitet behövdes en utvärdering.<br /> <br /> Målet med examensarbetet är att utföra utvärderingen av EmWat 4000 för UNICEF i Etiopien med avseende på hur vattenreningssystemet har fungerat, att identifiera begränsningar samt att undersöka hur anpassningsbart systemet är till olika förhållanden i Etiopien. För att uppnå målet har arbetet indelats i tre aktiviteter: tester av den mikrobiella kvaliteten på dricksvattnet som producerats på tre olika platser, utvärdering och summering av resultat från tidigare driftstillfällen och utförandet av två fullskaletest för att undersöka hur olika tänkbara åtgärder kan påverka reningsprocessen. Besöken på de olika platserna syftade även till att samla praktiska erfarenheter av systemet samt problemen som kan uppstå vid drift.<br /> <br /> EmWat 4000 är ett komprimerat vattenreningssystem som är lätt att transportera och kan producera upp till 4000 liter dricksvatten per timme. Systemet är speciellt anpassat för katastrofhjälp där det finns ytvatten att tillgå. EmWat 4000 är uppbygg av fyra olika reningsprocesser: flockulering, sandfiltrering, aktivt kolfiltrering och klorering. I utrustningen ingår fyra olika kemikalier för flockuleringsprocessen. Av dessa är två koaguleringskemikalier och två flockuleringskemikalier. Typen av kemikalie för vattenreningen bestäms utifrån kvaliteten på råvattnet som skall användas. Klor doseras från en behållare där hypoklorittabletter har placerats.<br /> <br /> Det huvudsakliga målet vid produktion av dricksvatten är att avlägsna patogena organismer. Därför bedömdes reningsgraden i systemet genom räkning av E-coli i det renade vattnet. Denna bakterie är en indikator på fekal förorening som medför en förhöjd risk att patogena organismer finns i vattnet. För att komplettera resultaten av bakterieräkningarna mättes turbiditet, fri klorhalt och pH för att bedöma disinfektionsförhållandena. Dessa uppmätta värden jämfördes sedan med rapporterade resultat från andra områden där EmWat 4000 tidigare använts.<br /> <br /> En del av fullskaletestet var att undersöka hur och till vilken grad antalet koagulerings- och flockuleringstabletter påverkar reningsprocessen. Filtreringssteget, där patogena organismer samt partiklar avlägsnas, kan avsevärt förbättras med hjälp av en effektiv flockulering. Kloreringen som oskadliggör de organismer som passerat filtret är enbart slagkraftig då partikelhalten är låg. För att optimera flockuleringssteget är valet av kemikalier för varje enskilt vatten avgörande. Därför testades olika antal och kombinationer av tabletter och dess olika effekt på turbiditetsreduktion i sandfiltret mättes. Vidare bestod fullskaletestet i att analysera hur flödet påverkade reningsgraden. Turbiditetsreduktionen, över sandfiltret, vid användande av designflödet på 4000 l/h jämfördes med det halverade flödet. Slutligen undersöktes även turbiditetsreduktionen i filtret med aktivt kol.<br /> <br /> Resultaten från de tidigare driftstillfällena bekräftade att EmWat 4000 kan producera dricksvatten av god kvalitet. Testresultaten från de platser som besöktes under detta arbete uppnådde dock inte WHO:s dricksvattenstandard. Den låga kvaliteten anses bero på att delar av utrustningen var skadad eller trasig samt att alla delar inte användes. Troligtvis hade filterenheterna gått sönder då vatten renats vid ett för högt flöde utan att säkerhetsventilen använts. Fullskaletestet visade att tillsatts av flockuleringsmedel medförde en markant förbättring av turbiditetsreduktionen då designflödet användes. Även sänkning av flödet visade förhöjd reningsgrad med avseende på turbiditet. Resultaten från fullskaletestet antydde även att kolfiltret inte har kapacitet att reducera höga halter av turbiditet. Praktiska erfarenheter av systemet var att det är lätthanterligt men kräver noggrannhet vid installering och drift för att erhålla acceptabel dricksvattenkvalitet. Dessutom visade sig manualen vara bristfällig i information och presentationen av denna samt även missvisande vad gäller turbiditets-gränsvärdet för klorering. Samtalen med driftsteknikerna gav intrycket att många var nöjda med EmWat 4000.<br /> <br /> Slutsatsen är att EmWat 4000 har kapacitet att producera dricksvatten av en acceptabel kvalitet, men, behovet av noggrann drift understryks. Designflödet skall ej överskridas för att förhindra att utrustningen skadas. Vidare skall mätning och kontrollering av vattenkvaliteten utföras regelbundet för att försäkra att WHO:s standard uppnås. Då snabb vattenproduktion är angeläget vid katastrofhjälp är det fördelaktigt att i första hand använda flockuleringskemikalier för att förbättra reningsgraden vid högturbida vatten. I andra hand kan flödet reduceras. Manualen bör förbättras och kompletteras med mer information för att möjliggöra bättre anpassningar till olika förhållanden i fält. För att förhindra att kolfiltret sätts igen bör det i manualen finnas ett gränsvärde för hur hög turbiditet som kan tillåtas passera. Slutligen, genom att uppmuntra att erfarenheter sammanställs och förs vidare kan effektiviteten vid framtida driftstillfällen förhöjas.<br /> <br /> (examensarbetet är utfört för avd.

studentPublicationsM2 Tautvydas Rindzevicius author Robin Prior author Programmes in Helesingborg v1000317 department At this point, railway switching systems exchange takes about 15 hours to perform. It means that long time is needed if performing multiple exchanges. It even means that traffic on tracks has to be disallowed for a long amount of time. It costs maintenance companies like Infranord a lot of money to keep tracks free from other vehicles during the work. The company needs to purchase special permission to be allowed to be the only company allowed on the tracks during that time. That adds up with costs of resources needed to perform the work. All put together, this demands a high budget. The shorter time workers need to be on duty – the less the company spends on human resources. If the company manages to cut time spent on performing the exchange of railway switching systems, lower budget is needed. It even means becoming a more attractive and competitive railway maintenance entrepreneur. Until now there has not been done specific research and analyses of processes during railway switches exchange processes. This should be done to find the most critical and time demanding processes. For that reason Infranord has suggested this thesis approach. By use of time studies, interviews and literature studies it should be possible to idfentify the most time demanding processes and give solutions to improve these. Time studies have been conducted and analysed to find the methods which are most effective. The time studies which have been done were performed on simple (two-ways) switches. The objective was to make it possible for the company of performing the railway simple – switch exchange within 8 hours. Analyses of time studies and assembled facts are shown as results and recommendations for Infranord. These are grounded on comparison of different methods of changing the switch. Every method has been presented by motivations and reference to time studies which have been done. Diagrams show the processes that are the most time consuming. https://lup.lub.lu.se/student-papers/record/3048374/file/8961518.pdf application/pdf 2805300 no 2012 swe växelbyte effektivisering tidsstudie förbättringsförslag Technology and Engineering 3048374 2012-09-03T00:00:00+02:00 2018-10-18T10:22:38+02:00 2012-09-04T00:00:00+02:00

studentPublicationsM1 Sara Josefsson author 3048477 Andreas Medin author 3048478 Fredrik Eng Larsson supervisor Engineering Logistics v1000260 department Background:<br /> With todays’ requirement of shorter product life cycles and faster time-to-market, producing companies experience an increased demand for faster transports in the supply chain. This puts pressure on freight forwarders to offer their customers a timely and reliable transport service at a reasonable price. Another challenge for the freight forwarders in Sweden is to provide such services in all parts of the country. Therefore, the actors in the 3PL industry must find an appropriate design for their transportation network which can enable these transports. This pressure is felt by Company X, which is the Swedish division of one of the largest freight forwarders of road transports in Europe. The network is operated by hauliers and contains of 25 terminals where some of them also function as hubs, which consolidate goods in order to increase the utilization of transports. Company X are now facing problems in meeting the scheduled delivery time for deliveries to northern Sweden. Since Company X strives for meeting its customers’ expectations it is wishful to develop a model based on a set of factors, which can evaluate the localisation of a hub and be a support for future decisions. Moreover, there has not been an evaluation of the main hub and its connected lines in the transportation network for many years. An analysis of the current network according to the model will therefore be conducted to identify the optimal hub localisation.<br /> <br /> Purpose:<br /> The purpose of this master thesis consists of two parts; first, to develop a model, which can evaluate the localisation of a hub, and second, to perform an analysis of the current hub location to find an optimal one according to the model.<br /> Research questions:<br /> The master thesis will answer the following questions to achieve the purpose:<br /> - Which factors have to be taken into consideration by Company X when deciding where to locate a hub?<br /> - How should the alternative hub localisations be identified and evaluated to arrive at a decision support for an optimal hub localisation?<br /> - What is the optimal hub localisation for the chosen lines according to the developed model and how reliable is the result?<br /> <br /> Method:<br /> The thesis is based on a systems approach since synergy effects are expected to arise between the factors in the constructed model. The development of the model is considered to be an exploratory and a normative study while the second part of the purpose will be an explanatory study. Both qualitative and quantitative data will be used in order to develop the model and to perform the analysis. The model is validated according to four steps to ensure the validity, reliability and objectivity. The validity of the analysis is investigated through performed sensitivity analyses.<br /> <br /> Conclusions:<br /> A number of factors affecting facility localisation were found in the literature and these were analysed to identify factors affecting the hub localisation for Company X. The following 16 factors were finally recognised to be considered when deciding where to locate a hub for Company X; highway access, labour availability, delivery time to customers, driving and rest periods, environmental regulations, construction feasibility, railway access, congestion, living costs and family conditions, location costs, wages, weather, closeness to similar companies, cost of return goods flows from northern Sweden, and closeness to nearby terminal to support goods handling at hub.<br /> <br /> A decision support model has been created consisting of four sub models. With a set of fixed data a Centre-of-Gravity analysis can be completed where a centre of gravity is achieved. A number of alternatives which fulfil the qualifiers, factors that the hub location needs to fulfil, are obtained. Next, the alternatives are evaluated according to a set of parameters, factors which are wishful to fulfil for the locations, and a parameter score is calculated. Moreover, the transportation cost for the alternatives is estimated. The output of the model is to be used as a decision support for hub localisation.<br /> <br /> Based on the analysis of the chosen transport lines the optimal hub location could not be distinguished, according to the model. Uppsala was the best alternative according to the parameter score, however, Gävle got the lowest transportation costs. Since the difference between the alternatives’ score and cost was marginal, it was not possible to identify the optimal hub localisation. In addition, there are aspects which are not included in this analysis that need to be considered before making a decision. https://lup.lub.lu.se/student-papers/record/3048452/file/3048476.pdf application/pdf 2384819 no 2012 eng Facility localisation optimal hub location decision support model Technology and Engineering ISRN LUTMDN/tmtp--5734--SE 5734 https://lup.lub.lu.se/student-papers/record/3048452/file/3055196.pdf application/pdf no 3048452 2012-09-04T12:57:21+02:00 2013-02-12T11:28:33+01:00 2012-09-21T12:01:47+02:00

This is no different for Volvo Bus Corporation, the second largest manufacturer of buses and bus chassis in the world, whose global product development organization is under pressure to find new ways to meet an increased amount of projects along with requirements on shorter lead times. For the Prototype Build and Test department, one actor in the product development process, this means that gains in process efficiency and effectiveness is needed to meet future demands.<br /> <br /> The purpose of this thesis is to map and analyze Volvo Buses’ Prototype Build and Test process, with a specific focus on the material supply process within the Prototype Build and Test department, in order to identify areas of potential improvement and suggest appropriate actions. Suggestion of a number of key performance indicators to measure the improvement of the process is also a goal for the study.<br /> <br /> The study uses a systems approach to provide a holistic view of the studied organization and to properly capture the complex interrelations within the system. The study is conducted through a case study where the bulk of the data is gathered using qualitative data collection methods, consisting of semi-structured interviews with representatives from all parts of the studied process. The data is analyzed through a theoretical frame of reference, developed by means of a literature study, based on the areas of process understanding, process mapping, process analysis, process improvement, process measurement and organizational structure.<br /> <br /> The analysis results in a set of process maps describing the core processes of Prototype Build and Test as well as its relation and connections to the rest of the product development process. The analysis identifies a number of issues; Insufficient process orientation, poor communication, lacking control over the material flow, unrealistic time and resource planning and unclear definitions of roles and responsibilities, all of which limits the process’ efficiency. The authors suggest a set of recommendation for how Prototype Build and Test, and the product development organization as a whole, should act to address these issues and increase the efficiency of the process. The recommendation to Prototype Build and Test are:<br /> <br /> - To start actively working with process orientation efforts<br /> - To regain control of the material flow by implementing improved delivery control, goods receiving and warehousing routines<br /> - To create clearly defined descriptions of roles and responsibilities<br /> - To initiate an evaluation of the time and resource planning routines<br /> - To start implementing a continuous improvement program<br /> To measure improvements in the material supply process KPI’s measuring delivery performance, goods reception and standstills in the prototype builds are suggested. https://lup.lub.lu.se/student-papers/record/3048484/file/3048490.pdf application/pdf 2999198 no 2012 eng Process mapping process management process improvement process- based organizational structure Technology and Engineering ISRN LUTMDN/TMTP--5732--SE 5732 https://lup.lub.lu.se/student-papers/record/3048484/file/3055185.pdf application/pdf no 3048484 2012-09-04T13:28:31+02:00 2013-02-12T11:28:19+01:00 2012-09-21T11:51:40+02:00

The project describes the interaction between expectations and<br /> needs, in and across situations, in order to be and feel prepared, relaxed, and while still well dressed.<br /> The Expectation of this project is that it should be an eye opener to take get new knowledge about<br /> how we dress, why we wear clothes like we do and how we optimize the environment for our body.<br /> In order to distinguish the garments in the concept from today’s apparel categories and clothing,<br /> whose names are coloured by individual associations and prejudices, the garments have been assigned<br /> new names “Sika” and “Kalorint”.<br /> The name “Sika” comes from the word “sicca” which in Latin means dry. The garment should be worn directly to the skin and<br /> the garment’s main purpose is just that; to keep the skin dry.<br /> The name “Kalorint” comes from Latin words “Calore” which means heat and the word “inter” which means between. The garment<br /> is the middle layer between the inner and outer layer and the garment’s main purpose is to keep the heat.<br /> The brief was to design a garment or a collection that targets a future, conscious and semi-active<br /> audience in 2015. The garment or garment’s function is to convey an identity, be presentable and be<br /> comfortable. There was also a personal brief based on the curiosity to explore and develop designer<br /> skills beyond the safe frame of a common industrial design project.<br /> Clothes are all around us: in shops around town, on the Web, in fashion magazines, dressed on people<br /> around us, in our closets, at night, during day, on the job, at the party - everywhere. They come in<br /> all different price ranges and in all different styles, almost. It may seem hard to come up with something<br /> new in the clothing industry, but if you look closely at what range the supply actually contains, it<br /> is still limited.<br /> Today, we see tendencies that indicate future trends that the previous conservative dress codes are<br /> going away, a personal style at work is requested and a more active society is awaiting. The project’s<br /> future scenario involves, among other things, that the car as transportation is replaced, even to and<br /> from work and other more dressed-up connection. Instead people will start choosing a cleaner and<br /> healthier alternative such as cycling, walking or similar. The target group is the conscious semi-active<br /> enjoyer of life.<br /> The fashion industry is working with categorizing garments into different “boxes”, which in most cases<br /> are linked to a situation: a party, at home, exercise, work, etc.. Part of the project has been to show<br /> that these categories often are linked and that there is a grey zone between and around these situations<br /> where the clothing need requirement has not yet been observed.<br /> An insight into the textile industry show a complex structure built up with different levels of innovative<br /> systems. It begins with a textile fiber that eventually forms into a fabric and then reaches all the way<br /> into a sewn garment with a given garment-name, a brand, an identity and an expectation. It is a<br /> complex structure that results in a load of trademarks, brands and trade names in different levels of<br /> the system.<br /> Clothes are meant to be used on the body. For optimal functioning the body requires a certain physical<br /> environment.

Denna metod begränsar i stor utsträckning utformningen av dessa flödesledare. Konstruktionen resulterar också i relativt stora effekt-förluster.<br /> Avdelningen för Industriell Produktion driver därför i samarbete med Magnetic Components Sweden AB (MagComp) ett projekt där dessa laminerade flödesledare ersätts med gjutbara flödesledare av mjukmagnetiska pulver-kompositer.<br /> MagComps gjutbara flödesledare kallad SM2C består av ett mer eller mindre legerat järnpulver i en matris av epoxi. Epoxin ger kompositen hög mekanisk styrka i kombination med hög järnpulverpackning. På grund av epoxins utmärkta vätningsegenskaper isoleras också varje järnkorn väl elektriskt. Detta är nödvändigt för att uppnå en energieffektiv flödesledare. Epoxin har dock ett antal nackdelar så som dålig temperaturtålighet och arbete med epoxin involverar relativt stora hälsorisker.<br /> I detta examensarbete undersöks därför möjligheten att ersätta epoxin med ett annat bindemedel.<br /> Arbetet började med en undersökning av tänkbara bindemedel. Efter en kort utvärdering testades de mest lovande av dessa bindemedel. De testmetoder som användes var framtagna för att ge en uppfattning om kompositens lämplighet som magnetisk flödesledare. I undersökningen ingick såväl polymera som keramiska bindemedel.<br /> De utförda testerna visade att andra konventionella polymerbaserade bindemedel har svårt att mäta sig med epoxin. Det framkom dock att vissa av de keramiska bindemedlen i vissa fall uppvisade bättre eller liknande egenskaper som epoxin.<br /> Det keramiska bindemedel Bindzil 50/80 visade sig ha minst lika bra egenskaper som epoxin i samtliga tester med undantag för mekanisk hållfasthet. Samtidigt var hanteringen av detta bindemedel kopplat till markant färre hälsorisker än epoxin. https://lup.lub.lu.se/student-papers/record/3051477/file/3051480.pdf application/pdf 2592207 no 2011 swe Technology and Engineering 3051477 2012-09-10T10:28:53+02:00 2012-09-10T10:41:48+02:00 2012-09-10T10:41:48+02:00

This<br /> model contents all different costs and factors that affects the total production cost<br /> for a produced unit. The aim is to develop an unique IT - support in relation to the<br /> model, which gives the opportunity to value and connect all parts in the production<br /> development chain. At the same time the IT - support will make it possible to split<br /> the detail production cost into every step in the manufacturing chain. This will<br /> make it possible to measure the result of different development efforts against each<br /> other in order to make it easier finding the most profitable ones, which means the<br /> lowest detail cost. At the market exists different kinds of softwares connected to<br /> company production lines, but no software fill the TESSPA - requirements.<br /> The aim of the present Master Thesis is to invent and analyse performance in<br /> existing production follow - up systems at different companies. The study is<br /> focused on three companies engaged in the TESSPA - project and one company<br /> not engaged in the project. The report is also intended to companies who supply<br /> and develop high - performance softwares and the authors have made restrictions<br /> due to the report time schedule.<br /> During the investigations it was important to distinguish between systems at the<br /> market and how these systems are used at the analysed companies.<br /> A several production follow - up systems and one business system has been<br /> investigated and analysed in the view of the TESSPA - requirements. It became<br /> relevant to analyse the companies production follow-up in its entirety to value<br /> their access to the required TESSPA - parameters. By interviews with different<br /> software suppliers it has been concluded that the existing systems are possible to<br /> develop and adapt in order to meet the TESSPA - specifications. A such<br /> development requires knowledge and consciousness in the TESSPA - concept at both developers and users, the manufacturing companies. The manufacturing<br /> companies influence the development by their software requirements while the demand is the most important development factor. https://lup.lub.lu.se/student-papers/record/3051587/file/3051632.pdf application/pdf 2882523 no 2008 swe Technology and Engineering 3051587 2012-09-10T13:12:43+02:00 2012-09-10T14:33:13+02:00 2012-09-10T14:33:13+02:00

The purpose is to further develop and verify a method o calculate the process cost at smaller companies with discrete part manufacturing and to identify improvement- and development potential. The work has been carried out in cooperation with the company, which usually manufactures series as small as 1 to 20 parts. The manufacturing equipment consists of CNC-machines and manual milling and turning machines. The company has grown a lot during the last years and has disregarded to develop an optimizing strategy for the manufacturing process. Two of the CNC-machines have been chosen to be analyzed and studied with help of two methods called Systematic Production Analyze and Manufacturing Economic Simulation. To acquire data a production performance matrix was developed for the two machines. The data was then gathered over a time of one week and then summarized in the matrix. The analysis has resulted in several measures that can reduce the process cost and simultaneously set free production time. Data should be gathered over a long period of time to get a more accurate process cost calculation. This is preferably done with a computer system with a user interface simple enough to let the operators concentrate on the manufacturing. https://lup.lub.lu.se/student-papers/record/3051643/file/3051644.pdf application/pdf 493575 no 2009 swe Technology and Engineering https://lup.lub.lu.se/student-papers/record/3051643/file/3051646.pdf application/pdf no 3051643 2012-09-10T14:38:09+02:00 2012-09-10T14:43:17+02:00 2012-09-10T14:43:17+02:00

Currently, the only way to fully determine whether or not such treatment is actually needed is an invasive procedure. In order to spare patients from the discomfort that it would involve, this essential step is often skipped and instead, antibiotics are prescribed regardless. Using Doppler ultrasound, it is possible to induce and measure acoustic streaming inside a cavity. This can be used in order to determine the nature of the sinus infection and hence avoid unnecessary prescriptions of antibiotics. In this master&#39;s thesis, a program was created which simpli_es and, to a degree,automates this new method of diagnosis. Using energy levels below the safety limits, set by the FDA, trial results were successful in inducing acoustic streaming velocities of 2 cm/s inside a phantom model. The method is ready to be used clinically using a pulse repetition frequency of 3.3 kHz. https://lup.lub.lu.se/student-papers/record/3051697/file/3051711.pdf application/pdf 5216349 no 2012 eng Technology and Engineering https://lup.lub.lu.se/student-papers/record/3051697/file/3629877.pdf application/pdf no 2012-01 3051697 2012-09-10T15:40:32+02:00 2014-10-08T14:47:01+02:00 2012-10-12T13:36:10+02:00

To be able to recognize early symptoms of this type of diseases it has proven to be important to investigate the mechanical properties of blood vessels. A few years back from now it became evident that the common carotid artery has a distinct bidirectional movement pattern in the longitudinal direction during each cardiac cycle. The mechanisms of this behavior has however since then been undetermined. In this study three independent indicators of the cardiac wall movements’ involvement is presented.<br /> By ultrasound examinations of both the right and left side common carotids and simultaneous examinations of left ventricle movement of the heart of 14 humans it has become evident that:<br /> The longitudinal movement in the carotid arterial wall, in both directions, occurs in parts of the vessel close to the heart before it is transmitted to more peripheral parts of the vessel.<br /> In every instance, the movement of the heart precedes the movement in the carotids.<br /> The motion forward on the right side carotid occurs before the motion forward on the left side.<br /> All these peaces of evidence suggests that the heart’s movement is the mother of, or at least significantly involved in, the longitudinal motion in the carotid arterial walls. https://lup.lub.lu.se/student-papers/record/3051799/file/3051802.pdf application/pdf 1440149 no 2012 eng Technology and Engineering 3051799 2012-09-11T08:53:04+02:00 2014-10-08T14:47:02+02:00 2012-09-11T09:01:01+02:00

More research and case-specific studies are required to understand the behavior of sediment transport mechanism in order to propose remedial measures. Sakuma dam on Tenryu River in Japan is one of the largest dams in Japan and it is rapidly losing its storage capacity due to sedimentation. The dam started its operations in 1957. To study the bathymetric changes upstream of the dam, a mathematical modeling approach was selected using HEC RAS to simulate the existing changes and predict future trends.<br /> Before going into the detailed modeling, a literature review has been made about different sediment-related studies on the river and Sakuma dam to get deeper insight and to build a conceptual model. Then a reach of about 32 km of Tenryu River, from Hiraoka dam to Sakuma dam was modeled. Google Earth and AutoCAD were used to extract the geometrical data of Tenryu River to be used as input in HEC-RAS. Other data about flow and sedimentation were obtained from the Department of Civil Engineering, University of Tokyo. As necessary, simplifications and assumptions were also made, and sometimes data was extracted indirectly. After initial data input, it was required to do calibration and validation of the model from 1957 to 2004, when the data were available. <br /> Once the model was validated, prediction of future bathymetric changes was also made through model simulation. For this prediction it was assumed that the existing flow data could be recycled. Predictive simulation shows that the dam would probably not serve its intended purpose after year 2035 ± 5. Therefore it is recommended to employ some suitable remedial measures to remove sediment and to prevent loss of storage in order to increase the useful age of the dam. Some prospective study options are also identified at the end. https://lup.lub.lu.se/student-papers/record/3051998/file/3052010.pdf application/pdf 2899988 no 2012 eng HEC-RAS sediment transport bathymetric change Sakuma dam Tenryu River.

Söderhallarna is a combined market hall with regular stores, restaurants and offices. A lot of people visit Söderhallarna daily, especially during the greater holidays, such as Christmas and Easter. Many non-Swedish speaking tourists visit the market hall, emphasizing the importance to have easy to understand signs and multi lingual evacuation alarms. After inspection of the object, four fire scenarios were chosen for further analysis. Simulations of the fire scenarios were made in FDS5 and controls where made in CFAST. From the FDS simulations, time to critical conditions was given regarding sight, temperature and smoke gas layer height. Simulex was used to simulate the egress of people. Three simulations per scenario were made, altering the mixture of people, giving a span for the egress time of Söderhallarna. The total time for evacuation is given by adding time to detection, decision and reaction. To compensate for variations the evacuation time was varied in @risk. By comparing the maximum time for evacuation with time to critical conditions a discrete result of whether evacuation can be securely done was produced. No injuries during evacuation are accepted, for scenarios presenting lacks in evacuation safety recommendations for improvement are made. https://lup.lub.lu.se/student-papers/record/3052020/file/3052021.pdf application/pdf 5764553 no 2012 swe brandteknisk riskvärdering utrymning Söderhallarna saluhall FDS CFAST Simulex @risk kritiska förhållanden brandscenarier brandgaslager simulering brand personsäkerhet beslut- och reaktionstid varseblivningstid förflyttningstid systematiskt brandskyddsarbete Technology and Engineering 9412 3052020 2012-09-11T13:13:03+02:00 2014-03-10T10:40:43+01:00 2012-09-12T13:00:56+02:00

The report is written by students in the fire safety engineering program at Lund University.<br /> <br /> The analysis determines three possible fire scenarios in different parts of the building, which are considered to have the worst probable outcome in terms of life safety. The scenarios were analyzed using CFD simulations and hand-calculations to determine at which time conditions become critical for persons in terms of view through smoke, temperature and radiation. These times where compared to the calculated time of a complete egress, which was determined using Simulex. The comparisons lead to a positive time margin in all cases where the sprinkler system worked as intended. A positive time margin means that the egress was completed before critical conditions were reached. When analyzing the scenarios without a working sprinkler system the time margin was in some cases negative, meaning life safety in case of fire could not be assured. To strengthen the fire safety of Sky City and to ascertain life safety in case of fire, measures were suggested in the report. Some measures have to be made and some are strongly recommended. https://lup.lub.lu.se/student-papers/record/3052031/file/3052034.pdf application/pdf 18218975 no 2012 swe Brandscenarier brandteknisk riskvärdering Sky City Arlanda Simulex Detact QS FDS CFD personsäkerhet utrymning effektutveckling kritiska förhållanden riskvärdering strålning.

The evaluation follows a scheme that was developed on a basis of prior learning at the Fire Protection Engineering Program and focuses on risks concerning life and health. The work started with an on-site identification of possible fire scenarios. The scenarios were ranked relatively to each other by comparing probabilities and consequences. The three most relevant scenarios were investigated further. Calculations were carried out regarding the spread of fire and smoke as well as evacuation. The conclusion is that fire safety at the hospital is almost satisfying, some efforts should be made to further improve the protection. Recommended improvements concerns better education of personnel and inspection of fire compartments to ensure that they are properly constructed. https://lup.lub.lu.se/student-papers/record/3052039/file/3052041.pdf application/pdf 14982170 no 2012 swe Brand brandscenario brandskydd brandteknisk riskvärdering CFAST DETACT QS effektutveckling ERM Jakobsbergs sjukhus kritiska förhållanden känslighetsanalys Locum personsäkerhet riskbedömning simulering utrymning Technology and Engineering 9415 3052039 2012-09-11T13:20:21+02:00 2014-03-10T10:40:43+01:00 2012-09-12T12:59:52+02:00

The report is a part of the course Fire Safety Evaluation given by the Department of Fire Safety Engineering and System Safety at the Lund Faculty of Engineering, Lund University in Lund, Sweden. Västerport Köpcentrum is a 5000 m2 shopping mall. The report evaluates three different fire scenarios and possibility to evacuate safely. The scenarios are simulated in FDS to see when critical conditions occur. The simulation program Simulex is used to estimate the time until the mall is evacuated. These two times are compared and conclusions are made. The report also gives proposals that should attend to improve the fire safety and some measures that are to be made by the law. https://lup.lub.lu.se/student-papers/record/3052057/file/3052058.pdf application/pdf 2710298 no 2012 swe Brandteknisk riskvärdering Detact-QS effektutveckling FDS galleria kritiska förhållanden känslighetsanalys Nyköping personsäkerhet Simulex utrymning värmestrålning Västerport köpcentrum Technology and Engineering 9417 3052057 2012-09-11T13:25:26+02:00 2014-03-10T10:40:43+01:00 2012-09-12T12:59:30+02:00

The report is a part of the course Fire Safety Evaluation, a course in the Fire Protection Engineering Program at Lund University, Faculty of Engineering, Lund, Sweden.<br /> <br /> The purpose with the report was to evaluate the personal safety in the building, specifically in regards to egress, in case of a fire. During the evaluation a large number of fire scenarios were analyzed and four fire scenarios were chosen and evaluated with fire simulations in FDS and egress simulations in Simulex. These fire scenarios were considered to be a fair representation of possible fire scenarios in the entire building.<br /> <br /> The analysis showed that a safe evacuation was not achievable, in parts of the building, before people were exposed to critical conditions. Mandatory and optional measures were proposed to ensure personal safety in the building in case of a fire. https://lup.lub.lu.se/student-papers/record/3052062/file/3052068.pdf application/pdf 6011089 no 2012 swe brandscenario brandskydd brandteknisk riskvärdering CFD DETACT‐T2 FDS kritiska förhållanden känslighetsanalys Nynäshamn osäkerhetsanalys personsäkerhet riskanalys riskidentifiering simulering Simulex sjukhus skola systematiskt brandskydd utrymning.

It evaluates the possibility to safely evacuate the premises if a fire occurs. Wallmans in Helsingborg offers dinnershows, where the guests are entertained while served dinner. After the dinnershow they close and reopen for nightclub. The maximum number of guests is 350 when dinnershow and 650 when nightclub. Three different fire scenarios have been analyzed, mainly with computer programs. The time to critical conditions has been compared with time for evacuation. The results indicate that the current situation at Wallmans is insufficient regarding human safety. To ensure human safety a number of suggestions has been made. If these suggestions or equated actions are not made, the human safety cannot be guaranteed in the premises. https://lup.lub.lu.se/student-papers/record/3052073/file/3052075.pdf application/pdf 6849132 no 2012 swe Brandteknisk riskvärdering nattklubb restaurang brandscenario effektutveckling utrymning personsäkerhet Wallmans i Helsingborg kritiska förhållanden FDS Simulex Pyrosim @Risk.

Kyrkskolan is an educational institution in the community of Svedala that houses a primary school, preschool and kindergarten. Parts of the building are roughly 100 years old and there has been a need to investigate if the fire safety is satisfactory with respect to present regulations and risk acceptance.<br /> <br /> The aim of this work has been to evaluate the fire safety with focus upon occupational safety. The work method is mainly based on a quantitative approach and some qualitative reasoning. Four critical scenarios in the building have been chosen for evaluation. Every scenario deals with a fire that is calculated and simulated in CFAST. In parallel, egress simulations are performed for each scenario in Simulex. A time margin is calculated for each scenario with collected time data for critical conditions and evacuation time.<br /> <br /> The results show unacceptable conditions for egress in most cases. @RISK is used to treat uncertainties and to show important factors that can be used to reduce the risks. Measures are evaluated and suggested in order to secure satisfactory safety. https://lup.lub.lu.se/student-papers/record/3052080/file/3052088.pdf application/pdf 4977836 no 2012 swe Brandteknisk riskvärdering personsäkerhet brandscenarier utrymning kritiska förhållanden tidsmarginal CFAST Simulex @RISK.

Gekås is Scandinavia’s largest department store with 4,5 million visitors a year. Three different scenarios were analyzed and simulated in the programs FDS and Simulex. The time to critical conditions were compared with the total evacuation time to see if the requirements for fire safety were fulfilled. The conclusion is that some important measures have to be taken at Gekås Ullared AB to secure safe evacuation conditions. Measures that shall be taken are as follows:<br /> <br /> - The evacuation alarm shall start when two detectors activates.<br /> - Optical alarms shall be installed in restrooms.<br /> - One door, BD1, shall be restored and fitted with push bars.<br /> - One door, BD35, shall be replaced with a door opening in the escape direction and<br /> fitted with push bars.<br /> - Emergency exits where people with disabilities can evacuate shall be marked.<br /> - An investigation shall be done to address the problem with the large amount of<br /> flammable goods. https://lup.lub.lu.se/student-papers/record/3052097/file/3052102.pdf application/pdf 6815544 no 2012 swe Brandteknisk riskvärdering BTR brandscenario kritiska förhållanden utrymningstid Gekås Ullared AB varuhus brandlarm rökfyllnad FDS Simulex.

The study is based on thirteen interviews with three local municipalities, one county administrative board, two national authorities and one private nuclear power plant company in Sweden. An extensive literature search was conducted in the area of capacity and cooperation, in the field of nuclear emergency preparedness and with help from the discovered literature, the answers from the interviews were analyzed. From the report, it is clear that capability is an immature field of study and that many actors are insecure when it comes to conduct the capability assessments that are required by Swedish regulations. Also, the report proposes some improvements within in the field of study. https://lup.lub.lu.se/student-papers/record/3052853/file/3052864.pdf application/pdf 4283221 no 2012 swe national authority county administrative board local municipality roles communication coordination cooperation assessment capacity capability emergency preparedness crisis management nuclear power Ringhals förmåga förmågebedömning samverkan samordning kommunikation roller kommun länsstyrelse myndighet krishantering kärnkraftsberedskap kärnkraftverk Technology and Engineering 1402-­3504 5385 3052853 2012-09-12T20:26:39+02:00 2014-03-10T10:40:43+01:00 2012-09-14T11:10:52+02:00

With market research supported by wide investigation of emerging technologies the proposed concept and its associated difficulties are divided into smaller and more apprehensive problems. By generating conceptual problem solutions to these smaller problems followed by substantial evaluation and further refinements more detailed concept solutions are obtained.<br /> The design is primarily focused on a “form follows function” basis, seeing as the need for a great functionality is more important than that of a perfect aesthetical design in extreme environments. However, since the sales success of the concept ultimately depends on customer preference, aesthetical needs are not neglected.<br /> <br /> Lastly these developed concepts are tested further and converged into a single final concept. https://lup.lub.lu.se/student-papers/record/3054116/file/3054122.pdf application/pdf 4162691 LU/LTH access 2012 eng Axis Communications Network Surveillance Camera Technology and Engineering 3054116 2012-09-18T10:57:30+02:00 2012-09-20T11:07:52+02:00 2012-09-20T11:07:52+02:00

studentPublicationsH2 Karna Dittmer author Giorgos Nikoleris supervisor Innovation v1000241 department In this master thesis a process in Delmia was created for digital test assembly. Delmia is a computer program for simulations, at Scania Delmia is used for simulating truck assembly. The process created was made to be easily reused in future tests. The base of the process came from the best practice document for manufacturing at Scania. To do this a study of the systems at Scania was made to get an understanding the primacies of the solution. Today digital tests are not possible to reuse because they are stored locally and because of this the parts are not updated from the Enovia database. By making a process in a template that can easily be copied in to a project the process can be used in many different projects. The parts in the template were linked to the process in the template was the same as the process of building a truck on manufacturing line. When new parts were exported to the project the same linking made the parts linked in to the right part of the process. This makes it possible to not have to link and organize the parts manually as much in the future. By saving the projects in the PPR-hub the parts could be updated every night. <br /> A big problem with using this solution it that a lot of parts geometry needs to be loaded which takes up a lot of time for the people working with the projects. One solution for this is to open the process in the step that the test is to be done in and to get all the parts up till then through using load with manufacturing context. https://lup.lub.lu.se/student-papers/record/3054203/file/3054204.pdf application/pdf 1900329 no 2012 swe Delmia Digital test assembly reusable process Technology and Engineering 3054203 2012-09-18T13:39:24+02:00 2012-09-18T13:42:55+02:00 2012-09-18T13:42:55+02:00

This workload is made up of small tasks, seemingly requiring small efforts that together and over time can cause considerable muscle wear. A large number of these tasks consist of opening packages constructed to ensure that the products are sterile. In this study, the effects these packages have on the users were examined, as well as possible ways of improving them to minimize the negative health impact they have on the users’ hands. The research was carried out at Helsingborg’s Hospital and Linero’s Community Health Center in southern Sweden.<br /> The problem was identified and described by means of observations, surveys, shadowing and interviews. At least 25% of the nurses who received the survey stated that they have trouble or pain of some sort in their thumbs, fingers or wrists. Observations and shadowing revealed that a major portion of the daily work performed by the nurses involved their hands. By studying the workday and every tasks performed, it became clear that dealing with packages made up a major part of the tasks involving hands.<br /> Brainstorming was used to come up with ideas that were then evaluated based on properties that were considered necessary, important and desired. The best ideas were realized as prototypes and used to perform a usability test. In the test, the prototypes were evaluated based on four statements concerning the force required to open, how easily the opening was performed, and how the performance felt. Combining the positive properties of the prototypes resulted in a final prototype and design. The final design has lips that are 30 mm long, 1.2 mm thick with an 18 mm radius hole in the middle of both lips. Two of the users from the original test group tested opening this final prototype, which confirmed that the combination of these properties resulted in a package that required less strength to open, was self-explanatory, easy to grip and comfortable to hold. This prototype was the basis of a written set of specifications presented to Region Skåne that aims to be of assistance in the purchase of more ergonomically designed packages. https://lup.lub.lu.se/student-papers/record/3054691/file/3054697.pdf application/pdf 5795968 no 2012 swe Hand ergonomics sterile packaging packaging design health care occupational injury Handergonomi sterila förpackningar förpackningsdesign vården arbetsskada Technology and Engineering LUTMDN/TMAT-5160-SE 3054691 2012-09-19T16:04:34+02:00 2012-10-08T10:35:10+02:00 2012-10-08T10:35:10+02:00

The main<br /> systems for transportation have been dominated by the Otto and Diesel engine for a long<br /> time, but both are trade-o in local and global emissions, i.e. NOX, soot, HC and CO<br /> versus CO2. This has driven the evolution to concepts as homogeneous charge compres-<br /> sion ignition, HCCI and later partially premixed combustion, PPC. Although HCCI has<br /> been shown to have ultra-low engine-out emissions in soot and NOX, has it been proven<br /> to be unreliable in terms of combustion control and lack in eciency at higher loads.<br /> PPC on the other hand is proven to be a good contester in both elds. This takes us<br /> to where we are now, where the PPC analyzing and testing phase is ongoing. PPC has<br /> been run with diesel as fuel, but with only a 25% of the conventional diesel combustion<br /> range, due to self-ignition 6. This problem has been solved by running high octane fuels<br /> with high resistance to ignite. These have shown to reduce emissions in soot and NOx<br /> as a result of longer air and fuel mixing period and high EGR values for a low combus-<br /> tion temperature. Ethanol has been tested with good results in eciency, combustion<br /> control and emissions. The growing market for renewable fuel in Sweden and globally 1<br /> indicates that this fuel is worth our eort for further investigation.<br /> This thesis attempts to characterize PPC with ethanol as fuel. It has been shown, based,<br /> and conrmed, that earlier testing by Manente 3 with double injection, EGR=50% and<br /> =1.5 are suitable for PPC operation. New results shows that an injection strategy with<br /> a pilot injection around -35 CAD ATDC, -5 CAD ATDC for second injection and an<br /> injection ratio around 52% give good eciency, low emissions and low acoustic noise at<br /> 12 bar IMEPg. In this operation does the second injection provide with control over<br /> the combustion duration. Earlier it has been stated that start of combustion (SOC)<br /> was triggered by second injection, but results show no connection. Trends show that a<br /> combination of, inlet temperature, lambda, and start of rst injection are key factors,<br /> as they all coincide in creating a fuel and air mixture which is igniting at its certain<br /> temperature. One can divide the combustion sequence in two parts. The pilot injection<br /> which provides with a sucient fuel and air mixture which kinetically ignites due to the<br /> high temperature just before TDC, causing a high rate of heat release. Followed by the<br /> second injection, which is partially kinetically ignited and partially stratied that burns<br /> in a diusion ame.<br /> Concerning combustion sensitivity to parameter variation, inlet temperature has shown<br /> to be an important factor, as variation of 5-10 oC clearly aects combustion in all<br /> aspects. With too high temperature, SOC and phasing are advanced resulting in loud<br /> acoustic noise and high combustion temperature, with too low inlet temperature SOC<br /> and phasing are retarded which also leads to high noise, as well as higher emissions with<br /> decreasing combustion eciency. Small variations of rail pressure, EGR and lambda does<br /> not aect combustion at the same proportion, but even so they are as important to be<br /> combined properly to gain a sucient ignition delay and combustion temperature. https://lup.lub.lu.se/student-papers/record/3054805/file/3054806.pdf application/pdf 3927639 no 2012 eng Ethanol premixed combustion Technology and Engineering 3054805 2012-09-20T10:11:52+02:00 2015-09-07T09:48:12+02:00 2012-09-20T14:49:24+02:00

Icing<br /> of wind turbines cause safety hazards, production losses and increased loads. This means that there is<br /> a need to develop a technique to quantify the icing climatology and corresponding eects on wind turbines<br /> to enable large scale wind power developments in the windy, sparesly populated areas of northern Sweden.<br /> This thesis is focused on evaluating the possibilities to estimate the long term icing climatology using<br /> mesoscale meteorological models in combination with existing ice models. The basis for the study<br /> were long term, low resolution time series from WRF and COAMPS in combination with high resolution,<br /> short term time series for the same geographical area, with the aim to nd a method for normal year<br /> correction of the icing climatology. A number of dierent methodologies for normal year correction of icing<br /> climatology were developed and evaluated using a few criteria: plausibility of the results, site dependency,<br /> sensitivity to data set used and sensitivity to the length of the time series used as reference. The ice modeling<br /> was performed using an implementation of the Makkonen algorithm for ice accretion. The normal<br /> year correction was performed using dierent theoretical reasoning and at dierent steps in the modeling.<br /> Linear regression of time series of standard meteorological parameters as well as of active ice hours and<br /> ice loads were tested. A method using iterative height adjustment of the parameters was developed as<br /> well as a basic method directly relating the high resolution modeled ice load to the low resolution modeled<br /> ice load. A method using averaged values for the dierent ice model input parameters was also tested.<br /> The evaluation showed promising results for the linear regression method. The dierent implementations<br /> showed feasible results and the outcome was not sensitive to the length of the correction basis. The<br /> height adjustment method was dicult to evaluate and was sensitive to the time series used as correction<br /> basis. The method using basic relations between high and low resolution parameters was extremely<br /> sensitive to the correction basis and the method based on averaged values did not show feasible results.<br /> Using active ice hours as basis for the normal year correction was shown to be preferable compared to<br /> using ice load.<br /> The conclusion drawn was that linear regression in combination with height adjustment to relate low<br /> resolution modeled icing climatology to high resolution icing climatology may be a promising tool. Development<br /> of the ice models used to estimate icing of wind turbines is needed, preferably a way to model ice<br /> directly on the wind turbine blades compared to the standard cylinder used in the Makkonen algorithm.<br /> Also, more reliable means to measure ice accretion are needed to enable further evaluation of the methods<br /> compared to the real icing climatology. https://lup.lub.lu.se/student-papers/record/3054826/file/3054832.pdf application/pdf 4330593 no 2012 eng ice modeling normal year correction icing of wind turbines mesoscale meteorological models Technology and Engineering 0282-1990 5254 3054826 2012-09-20T11:02:19+02:00 2012-09-20T14:50:49+02:00 2012-09-20T14:50:49+02:00

Customers are equipped with a display, connected to the<br /> smart meter, which shows the consumption in real time. Customers with smartphones<br /> can also follow their consumption in their phones by using an application.<br /> During the experiment the participants will be facing 5 different phases, with a<br /> purpose to motivate savings in different ways.<br /> Parallel with the experiment a scientific study is taking place at the Department<br /> of Energy Sciences, Faculty of Engineering, Lund University. The study is divided<br /> into two Master´s thesis. The purpose of the study is to investigate if the energy<br /> consumption in Swedish households can be affected by making it visual to its users.<br /> For example, is it possible to make savings by setting up a target for the reduction?<br /> This is the first of two reports with the purpose to give a theoretical platform for<br /> the evaluation and also examine the preconditions and the participant’s comments<br /> on the equipment. This report is divided in two parts.<br /> The first part is a literature study that starts with the chapter about the use<br /> of energy in small houses. Here is the direct and indirect energy use described in<br /> four different function areas. The following chapter describes feedback related to<br /> energy use and in which ways this can be given. Results from previous studies are<br /> also presented showing that energy savings between 5 to 12 % is the most common.<br /> There are also examples showing that savings up to 20 % are possible. Factors<br /> affecting our behavior are described in the chapter about behavior change. A couple<br /> of models used to explain behaviors are also presented in the same chapter. The<br /> last chapter in the first part is about energy saving advices.<br /> The second part of the report contains results from the two surveys that have<br /> been made. The first one was distributed to the 7 457 participants that, by the time<br /> of the survey, had installed the equipment. The rate of response was 65.6 %. The<br /> main part of the respondents was male with a high interest for technology. They<br /> v<br /> vi<br /> were also more interested in saving money instead of the environment. The few<br /> females that participated thought that the environment was more important than<br /> their interest for technology but saving money was the most important reason. Most<br /> of the respondents thought that they had good knowledge of their consumption.<br /> Despite that, 21 % answered that their consumption was lower than the limit of<br /> minimum 10 000 kWh per year for participation in the experiment. The conclusion<br /> that was made from this was that the participants overrated their own knowledge<br /> and underrated the consumption. Most of the respondents put a lot of effort in<br /> putting up their target for reducing energy. The mean value of the target for energy<br /> reduction was 8 %, which they thought was something between easy and difficult.<br /> The purpose of the second survey was to analyze the respondent’s thoughts<br /> about the display. The survey was sent out to 9 859 and the rate of response was<br /> 30 %. One important conclusion was that the display was seen as a valuable tool for<br /> energy savings. Respondent’s that use the display more than once per day was more<br /> able to see that they could save electricity. They were also more convinced that they<br /> would achieve their targets. The interest for further functions in the display was also<br /> analyzed. The respondent’s thought that they should be able to see the difference<br /> in consumption between today and yesterday. They also thought that the display<br /> should show the consumption, day by day, during the last week. At the moment,<br /> there is a relatively week interest in paying for the service but it will increase if the<br /> service was working properly. https://lup.lub.lu.se/student-papers/record/3054833/file/3054836.pdf application/pdf 5627856 no 2012 swe energisparexperiment energianvändning energifeedback Technology and Engineering 0282-1990 5255 3054833 2012-09-20T11:10:41+02:00 2012-09-20T14:52:35+02:00 2012-09-20T14:52:35+02:00

Hydrogen economy<br /> can represent a good alternative. To get it, developing carbon-free renewable hydrogen production<br /> processes will be crucial. This Master Thesis is focused on the ones using solar thermal energy to split<br /> water. At first, world’s energy situation is analyzed to introduce the need of alternatives like hydrogen.<br /> Then, main hydrogen production processes are classified and discussed. Nowadays 96% of hydrogen<br /> production is based on decarbonizing fossil fuels. Even though, there are different renewable alternatives<br /> developed or under developing, which are expected to take a main role in the middle and long term.<br /> Among them, thermochemical cycles are a good solution to split water using solar thermal energy,<br /> especially two-step cycles like ZnO/Zn. Taking this one as an example, viability of a large-scale hydrogen<br /> production implementation using thermochemical cycles is analyzed at different levels: solar technology,<br /> energetic efficiency and economical status and perspective. I conclude that this process is viable<br /> nowadays, except for the economical level. It requires financial support in the first states of its commercial<br /> development, but not necessarily in its middle and long term. In those, could represent a great pathway to<br /> produce carbon-free renewable hydrogen. https://lup.lub.lu.se/student-papers/record/3054875/file/3054878.pdf application/pdf 6877405 no 2012 eng hydrogen production thermochemical cycles decarbonisation solar thermal energy carbon-free energy Technology and Engineering 0282-1990 5256 3054875 2012-09-20T14:19:15+02:00 2012-09-20T14:53:49+02:00 2012-09-20T14:53:49+02:00

This study treats the direct injection of fuel at high pressures (c.a. 1500 bar). Ignition is not simulated in this work since this is intended to be a previous step for future studies which include combustion. A combination of LES for turbulence modeling and LPT for liquid phase modeling, which is a rather new approach, has been used and its advantages and limitations are reviewed herein. Six different simulations with different conditions as: mesh resolution, number of injected parcels, droplet size distribution and initial turbulence field; have been performed, analyzed and compared to ECN Sandia Spray A experimental results. OpenFOAM, which is an open source flow solver, has been employed in this study. Vapor penetration results for the best case have a good agreement with experimental results, with a maximum relative error of 5.77%. However, liquid length predictions are highly inaccurate in every case, as a consequence of the usage of a droplet size distribution in the nozzle outlet instead of implementing an atomization model In diesel engines, a very accurate description of the liquid zone is not required, but a good description of the vapor distribution is preferred. This makes this work useful in this area. Furthermore, LES-LPT involves a low computational effort compared to Eulerian techniques, becoming it a feasible approach to be used along with reaction schemes. https://lup.lub.lu.se/student-papers/record/3054883/file/3054891.pdf application/pdf 4325387 no 2012 eng Diesel spray injections LES LPT Technology and Engineering 0282-1990 5258 3054883 2012-09-20T14:29:57+02:00 2012-09-20T14:47:25+02:00 2012-09-20T14:47:25+02:00

The characteristics are advanced and it takes powerful tools to model a shock absorber. Öhlins Racing AB in Upplands-Väsby is looking for a tool to physically describe their products; in this thesis the task is performed by using the modeling language Modelica and the simulation tool Dymola. The modeled product is named Öhlins TTR and the work takes place at Modelon in Lund. First a literature survey was made to get a glimpse in what was created previously and it showed that only a few detailed shock absorbers have been modeled. To understand the modeling work a certain understanding of both Dymola and shock absorbers in general is required. Therefore this thesis gives a short introduction into how Dymola works and a technical description of the shock absorber. The model is built up by both components available in Dymola and self-made components. Valve system, cylinders, oil and other physical phenomena are built and then connected in order to simulate the complete model. Detailed descriptions will be given on how each part was modeled, the descriptions will be given both with mathematical derivations and images from Dymola. The measurements was made at Öhlins; in a flowbench to measure flow through valves and in a dynamometer (both with sinus shaped position and speed ramps) to measure the damper force. The simulation results are then compared to the measurements data and some parameters in the model are being adjusted in order to get a better match. It turned out that the model gave good results and did reflect much of the shock absorbers complex characteristics. https://lup.lub.lu.se/student-papers/record/3054933/file/3054937.pdf application/pdf 2809958 no 2012 swe Stötdämpare modelleringsspråk Modelica simuleringsprogram Dymola Technology and Engineering 0282-1990 5259 3054933 2012-09-20T15:45:43+02:00 2012-09-20T15:51:01+02:00 2012-09-20T15:51:01+02:00

These fluids were the best to use according to the respective authors. The result is generated with the main code of the program but using a different solver. The result section consists of multiple temperatures while the main program is designed to be used with one fix heating and one cooling temperature. Also a turbine calculation was written to be coupled with the main program.<br /> The results show that superheating have a negative impact on the output power and should be kept as small as possible. Some fluids however should have some superheating to avoid moisture in the expansion process. There are three types of fluids that is found: wet, dry and isentropic. The wet fluids are the ones that should have a degree of superheating as their expansion process otherwise might end in the wet region of the T-s diagram i.e. moisture at the end. <br /> The cooling has a major impact on the performance. A fluid that’s the best performing with a low cooling temperature isn’t necessary the best if the cooling temperature is increased.<br /> As the superheating should be kept low the main program uncertain parameter, if the user should define the pinch-point to the heating media or the amount of superheating, is set to last the mentioned https://lup.lub.lu.se/student-papers/record/3054940/file/3054947.docx application/vnd.openxmlformats-officedocument.wordprocessingml.document 5339688 no 2012 eng fluid selection maximum power output superheating cooling Technology and Engineering 0282-1990 5261 3054940 2012-09-20T15:51:08+02:00 2012-09-20T15:59:55+02:00 2012-09-20T15:59:55+02:00

In order to do this<br /> the current way of working with capacities is investigated prior to the actual<br /> implementation of the process. The key contribution of the authors is the<br /> development of a template to support the implementation process and ensure<br /> accurate capacity figures and support the capacity planning process. After the<br /> implementation the One Supplier Capacity Process is evaluated with regards to<br /> its key components, its implementation, and the results and potential to improve<br /> the capacity planning process for IKEA and its suppliers.<br /> Methodology: As the authors were actively involved in the implementation phase by adapting<br /> the One Supplier Capacity process to the specifics of plastic production, the<br /> chosen methodology was participatory action research with a normative<br /> approach. The study is deductive and mainly qualitative based on interviews and<br /> observations of IKEA employees and suppliers.<br /> Conclusions: The One Supplier Capacity Process provides a much needed framework for<br /> working with capacities that is lacking today. With the support of the template it<br /> provides a standardized method of calculating the capacities to ensure their<br /> accuracy, and allows allocation of production resources shared between products.<br /> It gives IKEA an insight into the suppliers’ productions that enable proactive<br /> work with regards to operationally maintaining availability. The insight should<br /> also enable IKEA to more efficiently secure tactical dedication of capacity at its suppliers. https://lup.lub.lu.se/student-papers/record/3055152/file/3055153.pdf application/pdf 9743519 no 2012 eng Technology and Engineering 12/5426 3055152 2012-09-21T11:04:50+02:00 2012-09-21T12:47:31+02:00 2012-09-21T12:47:31+02:00

Since many of the corporations’ markets are mature and highly competitive there are low margins and hence a constant need for new and improved products, processes and services to maintain profitability. There is also a constant increase in complexity and cost of research and development, which has made Lantmännen interested in increasing the use of open innovation. The purpose is to find a way to share costs and decrease the risks associated with research and development, and also gain access to a richer flow of ideas and innovations.<br /> Purpose The purpose of the thesis is to improve and extend Lantmännen’s processes within open innovation. Objectives include studying existing theories and models within open innovation and creating a model that suits Lantmännen. With this model Lantmännen’s existing processes within open innovation will be analyzed and opportunities for improvement identified.<br /> Methodology Substantial literature reviews on existing theories and models within open innovation have been carried out. https://lup.lub.lu.se/student-papers/record/3055162/file/3055164.pdf application/pdf 727036 no 2012 swe Open Innovation Blue Ocean Strategy Innovation Management Technology and Engineering 12/5416 3055162 2012-09-21T11:13:37+02:00 2012-09-21T12:48:44+02:00 2012-09-21T12:48:44+02:00

studentPublicationsM1 Gustaf Heverius author Mohammed Younis author Bertil Nilsson supervisor Production Management v1000259 department Issue of study For the past ten years there has been a remarkable growth in the wind power industry. During 2003 - 2010 the production capacity increased by 456 % in Sweden, corresponding to total capacity of 2019 MW. An additional 754 MW was installed in 2011, and there is a planned capacity installation of 950 MW for 2012. This will, according to a prognosis from Svensk Vindenergi, generate a power production of 7.7 TWh in 2012 and 11 TWh in 2013. Furthermore, if the expansion continues at this rate, wind power will correspond to about 10 % of the total power production in Sweden by 2015.<br /> Despite the rapid growth wind power projects are still dependent on government subsidies, i.e. green certificates. However, as the business continues to grow so do the technological advancements, thus providing new and more efficient wind turbine designs. Both incrementalas well as novel solutions have been developed over the years. In order to find new dominant designs they need to be evaluated both from a technical and a business point of view.<br /> Purpose The purpose of this study is to investigate the possibility for technology development to further strengthen the Swedish wind power business case, and ultimately examine the potential for eliminating the need for government subsidies.<br /> Objectives The objectives of this thesis are the following:<br /> Scan for trends in technology development and choose areas according to the scope and delimitations of the study.<br /> Evaluate the chosen technical areas – both financial and non-financial aspects.<br /> Depending on the outcome in the previous evaluation discuss the implications for the case company.<br /> Methodology A case study with an analytical approach has been performed for the development of the evaluation method, which consists of both qualitative and financial measurements. The qualitative aspect is covered by a method for technology concept selection, which assesses technologies based on several criteria. These criteria have been developed through literature studies and interviews with concerned stakeholders in the wind power industry. The financial aspect is covered by a capital budgeting model, intended to assess the cost of the wind power case including all costs over its lifetime, capital expenditure, operations and maintenance, and cost of capital.<br /> Conclusion A potential for single technology advancements to sustain the business case’s independence from green certificates has been identified. The technological development is mainly focused on increasing turbine size, i.e. generator output and rotor diameter. However, other incremental implementations have shown potential of business case improvements as well. https://lup.lub.lu.se/student-papers/record/3055167/file/3055177.pdf application/pdf 1476227 no 2012 eng Green certificates technology development onshore wind power wind turbine generator (WTGs) business case evaluation Technology and Engineering 12/5419 3055167 2012-09-21T11:18:20+02:00 2012-09-21T12:48:23+02:00 2012-09-21T12:48:23+02:00

However, seizing new opportunities often imply<br /> changes within the organization, and projects associated with change are<br /> bound to encounter resistance. To efficiently manage change and thereby<br /> avoid resistance and engage in measures that generate support for change, is<br /> therefore important in order to successfully address an opportunity. As<br /> change is always unique, no generic tools for managing change exist.<br /> However, in order to generate support it is essential to clearly communicate<br /> the impact and benefits of a project, which a business case (BC) is a<br /> common tool for.<br /> Company X has identified the indirect sales channel, where products are<br /> sold through partners, as an opportunity to increase sales. Certain regions<br /> within Company X utilize an indirect sales channel today, however the<br /> majority of the regions solely sell products directly to end customers.<br /> Increasing the use of partners as an extended sales force is a way of<br /> reaching new customers and broadening the customer base. In order to<br /> address this opportunity the Indirect Sales Program (IS Program) has been<br /> formed. The IS Program aims at establishing and expanding indirect sales in<br /> all regions, and the program is currently developing a new indirect sales<br /> IV<br /> model including tools and processes that enable regions to efficiently sell<br /> products via partners.<br /> Problem<br /> Discussion<br /> All regions within Company X are responsible for their own business<br /> decisions, and to make the decision of establishing indirect sales would<br /> imply many changes for the regional organization. Also, most regions lack a<br /> general understanding of the IS Program, the indirect sales model, and the<br /> benefits of establishing an indirect sales channel. There is an uncertainty of<br /> which processes to put in place, what personnel to involve, and the amount<br /> of resources to allocate. In order to successfully establish indirect sales, the<br /> IS program therefore needs to convince the regions to actively support and<br /> implement the indirect sales model. A business case that communicates the<br /> opportunity of the indirect sales channel as well as its associated benefits<br /> and costs is consequently needed.<br /> Purpose<br /> The purpose of this study was to explore how a business case can work as a<br /> tool for generating support for a change project. In order to achieve the<br /> purpose, a business case concerning indirect sales was developed for the IS<br /> Program. The business case was implemented in collaboration with a region<br /> and its ability to generate support was analyzed.<br /> Methodology<br /> The project started with a literature study. Thereafter a regional business<br /> case concerning the indirect sales channel at Company X was developed<br /> through adherence to the literature study. The business case was created as<br /> two parts; a guide and a financial model. The business case’s ability to<br /> generate support was tested through a regional implementation, and<br /> and<br /> analyzed in a theoretical context. Thereafter conclusions were drawn.<br /> Frame<br /> of<br /> Reference<br /> The frame of reference introduces three theoretical fields. The first field<br /> grants the reader an understanding of different sales channels, and more<br /> specifically the indirect sales channel. The second field discusses business cases in general and emphasizes the business case format. This field was<br /> used to structure the empirics and the business case development. The third<br /> field concerns resistance to change and underlines what initiators of a<br /> change project should do to generate support for a project. This field was<br /> primarily used when analyzing the indirect sales business case’s ability to<br /> generate support, however it also served as inspiration when developing the<br /> business case. The frame of reference ends with a framework illustrating<br /> how the theoretical fields are applied.<br /> Conclusions<br /> and<br /> Recommendations<br /> A business case can work as an efficient tool for generating support for a<br /> change project, as the indirect sales business case had a good ability to<br /> generate support from decision makers and implementers. However, a<br /> business case’s ability to generate support is limited by the capabilities of<br /> those developing and implementing it. They have to convey its message in a<br /> convincing way and communicate the business case appropriately. When<br /> using a business case as a tool for generating support for a change project it<br /> is essential to identify possible uncertainties associated with the change<br /> project, and to define if and how the business case can clarify these<br /> uncertainties. It is also crucial to devote time to communicate its content,<br /> and involve stakeholders and implementers in the business case<br /> development.<br /> The indirect sales business case’s ability to generate organizational wide<br /> support could be enhanced by incorporating more information concerning<br /> employees’ roles in the indirect sales business. The business case can be<br /> improved with regards to risk assessments, investment alternatives, and<br /> performance appraisal systems. The business case was intended to be<br /> generic. It has however been concluded that it can never be truly generic<br /> since all regional circumstances could not be accounted for.<br /> As a recommendation to Company X, the implementation process should be<br /> a collaborative process involving the IS Program and regional<br /> representatives. The implementation should be an iterative process where<br /> the implementation process and the business case are continuously<br /> improved. https://lup.lub.lu.se/student-papers/record/3055213/file/3055220.pdf application/pdf 1589242 no 2012 eng Technology and Engineering 12/5425 3055213 2012-09-21T12:21:12+02:00 2012-09-21T12:48:16+02:00 2012-09-21T12:48:16+02:00

The following research questions were formulated:<br /> How does gamification work and what are the underlying psychological factors?<br /> How can Cybercom implement a game layer on their employee development process?<br /> Method: This thesis has used a combination of a qualitative and a quantitative approach to accurately capture the complex relations of the employee’s motivations and obstacles for using the competence model, which is their employee development process. Data was gathered through a thorough literature study, internal interviews with employees, meetings with companies, specialised at gamification, and internal quantitative surveys. The gathered data served mainly as input for psychological frameworks and frameworks related to game design.<br /> Results: The analysis showed that the employees of Cybercom are motivated by self-actualisation but not by competition or status, which means that the game layer needs to focus on the individual development and not by comparing progress. By analysing the employee development<br /> process, it was concluded that the main activity of the game should be to write a log of the employee’s activities. The game layer also needs to focus on increasing ability (usability) since their motivation only can be raised to a certain degree due to limited in-system time. The results also include an account of the underlying psychological factors that explains the effect of gamification. The suggested game design is also presented in the proof of concept of this thesis. https://lup.lub.lu.se/student-papers/record/3055223/file/3055224.pdf application/pdf 3282999 no 2012 eng Gamification Enterprise Gamification Game Layer Employee engagement Behavioural change Employee development Technology and Engineering 12/5421 3055223 2012-09-21T12:27:34+02:00 2012-09-21T12:48:08+02:00 2012-09-21T12:48:08+02:00

There is also<br /> an ambition within the organization to improve the<br /> sales in Canada by exploring previously unknown<br /> market opportunities. The needs for increased<br /> knowledge are experienced both at the Canadian<br /> sales office and at the Lund headquarters. To be<br /> able to make the right strategic and marketing<br /> decisions, Company X Equipment division needs<br /> in-depth knowledge about the end-users’ current<br /> needs together with information regarding trends<br /> for the Equipment division’s application areas.<br /> The experienced need for increased knowledge<br /> implicates an improvement potential within the<br /> process of generating marketing information.<br /> Company X has furthermore expressed desire to<br /> improve within that area. Generating marketing<br /> information is a cornerstone in a market-oriented<br /> IV<br /> organization according to Mohr et al (2010) and<br /> by improving the marketing information system<br /> (MIS); there is a possibility for Company X to<br /> increase its degree of market orientation<br /> accordingly.<br /> Purpose: The main purpose of this master thesis is to<br /> conduct a market research and map the market<br /> potential for some of the Canadian application<br /> areas within Company X Industrial Equipment<br /> division. Furthermore, the thesis also describes<br /> and explains the current and future development<br /> of the end-user needs within the markets.<br /> The secondary purpose of the thesis is to analyze<br /> Company X ‘s MIS (marketing information<br /> system) and give Company X a recommendation<br /> of improvements in order to achieve a higher<br /> degree of market orientation and thus reduce the<br /> risk of future knowledge gaps.<br /> Methodology: The research was conducted through a<br /> combination of a descriptive and an explanatory<br /> case study in order to achieve an in-depth<br /> knowledge of the underlying potential of the<br /> Canadian market and the processes of gathering<br /> market information within Company X and<br /> Company X Canada. The research was mainly<br /> qualitative and the information origins from<br /> several in-depth interviews together with written<br /> second-hand information from literature, articles<br /> and e-sources. In order to quantify the market<br /> potentials, quantitative second-hand data was<br /> used and combined with qualitative and<br /> quantitative first-hand empirics from interviewees.<br /> The interviews were held at Company X in Sweden and in Canada as well as externally with<br /> different stakeholders in Canada.<br /> Conclusions: The total potential and the size of a market are<br /> determined by how it is defined. Consequently, in<br /> some of the application areas studied, the<br /> Canadian market potential estimated differs from<br /> the one currently assumed by Company X. All the<br /> markets currently have low growth rates and a<br /> high amount of existing users. Thus, the bulk of<br /> the value is in the replacement markets, where<br /> Company X is observed to currently be less<br /> present and where the knowledge is lower<br /> accordingly.<br /> There are currently some gaps in Company X’s<br /> way of gathering external marketing information<br /> about the Canadian markets. Those gaps create<br /> a weakness in the MIS that connects the<br /> Canadian markets to the decision-making<br /> processes within the organization. Improved MIS<br /> have potential to improve the current market<br /> knowledge and in the long run – increase<br /> Company X’s degree of market orientation and<br /> thus improve both the strategic and the marketing<br /> decision qualities. https://lup.lub.lu.se/student-papers/record/3055233/file/3055236.pdf application/pdf 7710885 no 2012 eng Market Research Market Orientation Marketing Information System Market Potential Technology and Engineering 12/5422 3055233 2012-09-21T12:40:43+02:00 2012-09-21T12:47:41+02:00 2012-09-21T12:47:41+02:00

Yangtze River is the biggest river in China and the area of whole river basin is about 1.8 million square kilometers covering more than one fifth of whole China area. At the same time Yangtze River basin has huge hydro-energy at 268 000 MW in theory and 197 000 MW exploitable. Meteorological data, installed capacity data and hydropower production data of Yangtze River Basin are collected for model calibration. The project study area is divided into three subareas according to their precipitation, temperature and geological conditions. And HBV-TR model is used on each of them. The calibration results cannot be judged by normal criteria due to the difficulty of lacking data. However, by using other supplementary means, some reasonable calibration results are obtained. In study area, the peak value of energy flow appears in summer time during June to September following the same pace of precipitation. In Upper area, the average annual energy inflow is around 8—20 GWh when this number in Middle area and Lower area is 200—300 GWh and 400—850 GWh respectively. https://lup.lub.lu.se/student-papers/record/3089181/file/3089188.pdf application/pdf 4789984 no 2012 eng Technology and Engineering 1101-9824 12/5011 Examiner: Rolf Larsson 3089181 2012-09-24T13:02:18+02:00 2019-03-27T16:05:43+01:00 2012-09-24T13:41:08+02:00

Planeringen sker i dagsläget<br /> manuellt vilket gör att slutresultatet kommer allt längre från det optimala.<br /> För att anpassa planering och transporter till den ökande efterfrågan krävs<br /> en grundlig genomsyn av transporterna. Studien ämnar därför göra en<br /> kartläggning och analys av transporterna för att undersöka vilken<br /> förbättringspotential som råder.<br /> <br /> Syfte: Vilka förbättringsåtgärder kan identifieras för att, genom ruttoptimering,<br /> möjliggöra ekonomiska såväl som miljömässiga vinster?<br /> <br /> Metod: Studiens uppbyggnad bestod inledande av explorativ och deskriptiv studie<br /> för att genom observationer, intervjuer och datainsamling få förståelse för<br /> de faktorer som påverkar ruttplaneringen och transporternas förfarande.<br /> Vidare gjordes en normativ studie där transporterna simulerades och<br /> analyserades med hjälp av ruttoptimeringsverktyget Route Planner.<br /> Inledningsvis analyserades förbättringsmöjligheterna med utgångspunkt<br /> från hur transporterna genomförs idag, i studien kallat Nuläge. För att<br /> analysera hur strategiska förändringar påverkar transporterna skapades två<br /> IV<br /> scenarion, leveranser med Nya tidsfönster samt leveranser Sex dagar i<br /> veckan. Samtliga analyser fokuserade främst på kostnader och miljö men<br /> även leveransservice och resursutnyttjande togs i beaktning.<br /> Slutsatser: Inledningsvis kunde ett flertal problemområden identifieras. Problemen<br /> ställde inte krav på omplanering utan snarare körbeteenden vilka anses<br /> vara relativt enkla att åtgärda. Om hälften av de identifierade problemen<br /> kunde elimineras skulle Bergendahls initialt sänka sina kostnader med 5<br /> procent per år och samtidigt minska sina emissioner med 5 procent.<br /> En förutsättning för att på sikt kunna optimera sina rutter är att<br /> Bergendahls hanterar problemområdena. Till följ av den ökande efterfrågan<br /> har den manuella planeringen blivit allt mer komplex vilket gör att<br /> ruttplanerarna får använda sig av olika planeringsåtgärder. Analysen visar<br /> att ett ruttoptimeringsverktyg många gånger kan hjälpa<br /> transportplanerarna att undvika de kostsamma åtgärderna.<br /> Genomgående i analysen visar resultaten att tidsfönsterna har en mycket<br /> begränsande inverkan på optimeringen. Förutsatt att Bergendahls hanterar<br /> sina problem kan de teoretiskt uppnå en 22 procentig kostnadsbesparing<br /> samt en emissionsminskning på 18 procent.<br /> Ett införande av leveranser sex dagar i veckan kan hjälpa Bergendahls att<br /> hantera problemen identifierade i studien. Förutom att minska kostnaderna<br /> får det också positiv inverkan på butiker och slutkunder. Problem: The manual transportation planning at Bergendahls Food has recent years<br /> become increasingly complex due to the growth in demand. In order to<br /> adjust to the changes, Bergendahls Food requires a thorough mapping of<br /> their transportation activities. The lack of supporting IT-system obstructs<br /> the ongoing transport review why this case study aims to map and analyze<br /> the transports in order to investigate the potential of improvements.<br /> <br /> Purpose: What improvements can be identified through route optimization in order<br /> to gain both economic and environmental benefits?<br /> <br /> Method: To get a deeper understanding of the elements influencing the route<br /> planning and transports, the initial part of the study consisted of an<br /> exploratory and descriptive analysis. In order to identify possible<br /> improvements a normative study was made in which shipments were<br /> simulated and analyzed using the route optimization tool Route Planner.<br /> The potential of improvements of the transports as they are planned today<br /> were primarily analyzed. Furthermore two different scenarios were<br /> developed to analyze how a strategic change of the transports could affect<br /> the flow of goods with their associated costs and emissions. The scenarios<br /> VI<br /> investigated were ‘New time-windows’ and ‘Deliveries six days per week’.<br /> All analyses were primary analyzed in a cost and environmental perspective<br /> but delivery service and resource utilization were also taken into<br /> consideration.<br /> <br /> Conclusion: Primarily a number of problem areas were identified. The situations did not<br /> require reorganization of the routs since the problems was connected to<br /> how the routes were executed. Therefore the problems seem easy to<br /> handle and eliminate. If half of the problems were eliminated cost savings<br /> could be as much as 5 percent annually. The environmental savings<br /> connected to the improvement could be 5 percent.<br /> In order to reach optimization, Bergendahl has to deal with the problems.<br /> Due to increased demand the manual route planning has become more<br /> complex. When managing, the transport planners use different solutions<br /> which are quite costly. The analyze shows that a route optimization<br /> software could help avoiding these planning solutions.<br /> Throughout the study the results show that the time-windows have a great<br /> influence on the optimization process. Assuming that Bergendahls is able to<br /> handle the problems cost savings could be as large as 22 percent. In the<br /> same time the emissions could decrease with 18 percent.<br /> Introducing deliveries six days per week could help Bergendahls to handle<br /> and eliminate some of the problems identified in the study. Besides the<br /> improvement of their own distribution, the improvements could have a<br /> positive effect on the stores and final customers. https://lup.lub.lu.se/student-papers/record/3089200/file/3089211.pdf application/pdf 1813290 no 2011 swe kostnadsbesparingar miljöbesparingar ruttoptimering Transporter Environmental Benefits Cost Benefits Route optimization Transportation Technology and Engineering https://lup.lub.lu.se/student-papers/record/3089200/file/3089213.pdf application/pdf no 3089200 2012-09-24T13:31:52+02:00 2013-02-12T11:30:17+01:00 2012-09-24T14:28:04+02:00

Birds aredecreasing in numbers day by day as a result of our actions and most severe is the situation within the intensified agricultural landscape.<br /> <br /> The goal with this project is therefor to increase the birds chance of survival by increasing the biodiversity within the landscape. This resulted in an artificial biotope that will create habitats for insects. The insects will in turn help the farmers with pollination and pest control on their land and become an important food source for the birds. The biotope will additionally provide the birds with water for them to drink and clean their feathers in. By integrating this artificial biotope into the intensified agricultural landscape a more diverse environment could be created that could benefit both birds and farmers. https://lup.lub.lu.se/student-papers/record/3098794/file/3098882.pdf application/pdf 7965789 no 2012 eng Arts and Architecture Technology and Engineering ISRN ISRN: LUT-DVIDE/EX--12/50168-SE 3098794 2012-09-25T13:59:55+02:00 2012-09-25T14:08:40+02:00 2012-09-25T14:08:40+02:00

The derived control design was compared to an uncontrolled system and the results state that the developed controller improved the performance of the system, concluding that it is possible to use event-based control on a server system. https://lup.lub.lu.se/student-papers/record/3112448/file/3112462.pdf application/pdf 1043614 no 2012 eng Technology and Engineering ISRN LUTFD2/TFRT--5904--SE https://lup.lub.lu.se/student-papers/record/3112448/file/3112464.pdf application/pdf no month=September 3112448 2012-09-26T09:35:43+02:00 2012-09-28T11:08:03+02:00 2012-09-28T11:08:03+02:00

studentPublicationsH3 Arnbjörn Einarsson author Babak Rajabian author Anders J Johansson supervisor Rolf Johansson supervisor Department of Automatic Control v1000253 department The aim of this master thesis is to compare two different control algorithms with respect to reference tracking and simulation time for a superconductive cavity in ESS. The two control algorithms are PID and MPC. The most common type of controller is the PID due to its simplicity. However, an increased interest in finding a control algorithm which can handle the reference tracking better than the PID controller, has been searched for better development of computers. The Model predictive control is a more advanced and requires more computer power. In this thesis the comparison is made using first a very simple cavity model and then extending it with Lorentz detuning of the cavity. Both these models are simulated with the two types of control algorithms. The result shows that both PID and MPC can manage the reference tracking well. In both cases, the controlled output is within its margins. However it can be seen that the PID has a faster response to the beam injection into the cavity. Due to the complexity of the MPC, this algorithm has a longer simulation time then PID. Furthermore the MPC calculates the control signal through an optimization problem. https://lup.lub.lu.se/student-papers/record/3115719/file/3115720.pdf application/pdf 1707287 no 2012 eng Technology and Engineering ISRN LUTFD2/TFRT--5905--SE https://lup.lub.lu.se/student-papers/record/3115719/file/3115722.pdf application/pdf no month=June 3115719 2012-09-26T11:50:47+02:00 2012-09-28T11:18:07+02:00 2012-09-28T11:03:13+02:00

studentPublicationsM1 August Falck author 3115732 Johan Lundin supervisor Engineering Logistics v1000260 department Upprinnelsen till detta examensarbete var att Otis Stockholm, som också leder den svenska verksamheten, saknade en processkarta för nymontageavdelning. Försök hade gjorts tidigare med att göra en processkartläggning, men man hade då inte kommit hela vägen. Man ville nu från ledningens håll ha en karta på processen så att alla gjorde på samma sätt från projekt till projekt. Processen var uppdelad i två funktioner, säljavdelningen och fältavdelningen, genom en kartläggning ville ledningen veta på vilken sida av de två funktionerna kostnaderna för projekten lades. Företaget ville ha kostnadsstyrning och tydliga rollfördelningar i projekten. Då författaren kom till företaget och diskuterade studiens upplägg blev syftet ett lite annorlunda upplägg och med mindre fokus på funktioner och mer på vilka förbättringar som kunde skapas. En nulägesbeskrivning enligt Ljungbergs et al. (2000) processbegrepp gjordes, och det gavs också rekommendationer för hur förbättringsarbete av processen skulle kunna möjliggöras i framtiden till exempel av mätningar och dokumentation.<br /> Som metod i studien användes en fallstudie som angreppssätt, där intervjuer lade grunden till en överblick för hur processen utförs i dagsläget. Författaren intervjuade representanter involverade i olika delar av processen. Genom intervjuerna och observationer på företaget och ute på fält kunde författaren skapa sig en helhetsbild av processen. Den har presenterats i löpande text, i tabellform och i en processkarta, det vill säga hur projekten utförs i det flesta fall i dagsläget. Utifrån denna kartläggning och med hjälp av processinfluerade teoristudier kunde det göras en analys över problem i dagens process och ges flera förbättringsåtgärder.<br /> Slutsatserna och de rekommendationer som författaren vill ge företaget är för det första en förändrad process med större fokus på kunderna och att få alla medarbetare på företaget att dra åt samma håll. För det andra att företaget bör skapa en grupp som fokuserar på partneringsamarbeten. Där det är viktigt att förstå hur dessa fungerar och hur man kan ta över kontrakten med de stora byggföretagen vartannat eller vart tredje år från konkurrenterna. Den tredje huvudsakliga slutsatsen som uppdagades under arbetets gång var att företaget bör fokusera mer på ett större utnyttjande av medarbetarnas olika kompetenser. Det är i dag en låg tro på medarbetarnas styrkor där chefer är de som kan och bestämmer i många av fallen. En större tillit och ändrade kontrollsystem skulle skapa en större lärande atmosfär där kunden hamnar i första rummet. Den fjärde rekommendationen handlar om mätning och mål. Det är viktigt att föra fram mått som de anställda arbetar med och förstår. Många av dagens mått är mycket svårbegripliga och skapar mer suboptimeringar än nytta. Författaren menar även att medarbetarna bör få mer resurser och tid för reflektion och uppföljning av teamets arbete i nymontageprocessen. The impetus for this thesis was the identification of the need for a process map for processing new equipment within Otis Sweden. The company had tried before to map their process but had not fully developed the model. This time managers wanted a process map to stabilize the process of managing employees to ensure consistency across projects. The process has been spit in two functions, the sales and the field department, who also have separate budgets. Management were interested to see the relative costs of each department and to have a clearer idea of what each side did during the process. When the author came to the company for the first time to discuss the purpose of the study, the focus turned from functions to possible changes, and a search for an improved process. The study maps the current situation and gives recommendations for development of the process; for example, through improvements in measurement and documentation.<br /> The methodology used was a case study, where semi-structured interviews were undertaken to give an overall picture of the process. Interviews worked through the process from start to finish, all those involved in the process gave their portrait of the process. The picture drawn from the interviews and the author’s observations at the company and in the field gave a complete picture of the process. A presentation of the process has been made in text, tables, and in a map.<br /> The conclusions the author would present to the company are fourfold: first there is a need for a clearer process with a stronger customer focus and which gives clarity of direction for the workforce. Secondly, a group should be set up to analyze the company’s possibilities to establish partnership with the four main Swedish building contractors. Thirdly, the company should make better use of the workforce and their competences, creating a learning organization where competences are used to develop the company through the sharing of ideas and know how. The fourth recommendation centers on targets and their measure. It is vital that targets and measures be simplified such that the workforce can readily identify and work with them. This can be achieved partly through measuring how the parts, and the process as a whole, create value for the customer. Even if targets and measures are initiated by managers, it is important that personnel are involved in the process of establishing them. It´s also important that these targets and measures are evaluated and that the company make changes if problems are discovered. https://lup.lub.lu.se/student-papers/record/3115728/file/3115731.pdf application/pdf 905641 no 2011 swe Processkartläggning process partnering ramavtal mätning kvalitet kundnöjdhet byggbranschen Technology and Engineering 3115728 2012-09-26T12:48:51+02:00 2013-02-12T11:30:32+01:00 2012-09-26T13:34:07+02:00

Ett steg i detta är att se om det finns några förbättringar att genomföra i lagerstyrningen i form av lager- och servicenivåer. Detta då de anställda upplever dagens verktyg som ganska trubbiga för det nuvarande produktsortimenetet och att detta kanske kan förbättras genom ytterliggare en dimension på det befintliga systemet i form av efterfrågemönster.<br /> Syfte:<br /> Syftet med examensarbetet är att förbättra lagerhanteringen genom att sänka lagernivåerna givet målet på servicenivån.<br /> Metod:<br /> Detta examensarbete har utförts med ett systemsynsätt. Det abduktiva metodsättet har applicerats på detta och författarna har rört sig fram och tillbaka mellan teori och praktik. Mycket numerisk data från många olika källor har använts under projektet vilket lett till en kvantitativ analys som har stöttats med kvalitativ analys i form av intervjuer.<br /> Teori:<br /> Teorin som använts i detta examensarbete är en blandning från olika länder och tidsepoker. Men eftersom mycket av den klassiska teorin för lagerhantering inte förändrats mycket under detta århundrade kan den därför bli sammanfattad från ett fåtal välkända författare som sedan stödjs av nyare teori.<br /> Slutsatser:<br /> Slutsatserna i detta examensarbete är uppdelade i några steg. Först och främst fastställdes det genom nulägesanalysen att produktsortimentet var ganska komplext och att det nuvarande systemet hade potential för förbättringar. En vidare analys visade att det fanns fyra tydliga efterfrågemönster och genom att dela upp produkterna efter dessa mönster så fann projektgruppen ett sätt att applicera detta på det befintliga systemet. Implementationen visade att förbättringar var möjliga i form av lagersänkningar med upprätthållen servicenivå, men att det för att lyckas med ytterligare förbättringar av servicenivån behövs ett mer sofistikerat system. Background:<br /> Nederman has a long term goal of improving their supply unit in Helsingborg. One step of this is to investigate if there are any improvements to be made in the inventory control in terms of stock levels and service level. This since the employees at Nederman believes that the existing methods are too blunt as a tool for the product range and that their methods can be improved by adding a new dimension on the existing system in terms of demand pattern.<br /> Purpose:<br /> The purpose of this master thesis is to improve the inventory control at Nederman by lowering the stock level given the goal of the service level.<br /> Method:<br /> This master thesis has been performed with a systems approach. An abductive research method has been used and the authors have been moving back and forth between theory and practice. A huge amount of numerical data from different sources has been used throughout the master thesis why most of the analysis has been quantitative, but it has been supported with more qualitative analysis in terms of interviews.<br /> Theory:<br /> The theory used in the master thesis is a mixture from different authors and time periods. But since most of the traditional theory for inventory control has been consistent the last decade it could therefore be summarized from a few well known authors and then supported with more recent theory.<br /> Conclusions:<br /> The conclusions of this master thesis are divided in a few different steps. It was concluded from the current state analysis that the product range was pretty complex and that the existing system had potentials for improvement. Further analysis showed four distinct types of demand pattern and by dividing the products according to this the authors found a way to apply this to the existing system. The implementation showed that improvements were possible in terms of a lower safety stock value with a maintained service level. But that it in order to make further improvements on the service level was needed an even more sophisticated system. https://lup.lub.lu.se/student-papers/record/3122499/file/3122508.pdf application/pdf 3950377 no 2012 eng Lagerhantering efterfrågemönster variationskoefficient beställningspunkt säkerhetslager Inventory control demand pattern coefficient of variance reordering point safety stock Technology and Engineering https://lup.lub.lu.se/student-papers/record/3122499/file/3122510.pdf application/pdf no 3122499 2012-09-27T10:31:03+02:00 2013-02-12T11:30:58+01:00 2012-09-27T10:48:31+02:00

studentPublicationsH2 Jonna Engström author 3125588 Karl-Axel Andersson supervisor Innovation v1000241 department Målet med detta examensarbete är att skapa ett koncept där kunden får möjlighet att påverka den visuella utformningen av höljen, och/eller utformningen av fästen till olika övervakningskameror. <br /> <br /> Axis Communications kunder har hela tiden ökande krav på snabbare leveranser och det finns ett växande behov av kundanpassade produkter. I detta examensarbete undersöks möjligheterna med additiv tillverkning, även kallat 3D printning, som en metod för att möta de ökade kraven. Idag används additiv tillverkning mestadels för att tillverka prototyper, men det finns en tro på att metoden även kan användas för att skapa färdiga produkter och göra mer kundspecifika tillbehör. <br /> <br /> För att uppnå detta syfte utvärderas olika tillverkningsmetoder och SLS (selective laser sintering) väljs som den mest lämpliga metoden. För att få projektets vidare inriktning utforskas olika kundscenarier, försäljningsalternativ utreds och en studie över potentiella installationsmiljöer utförs. <br /> <br /> Huvudfokus är att visualisera konceptet genom att utveckla ett monteringsfäste och ett hölje som passar till utvalda modeller av Axis Communications kameror. Dessa tillbehör är skapade för att visa möjligheterna med en parametrisk design och hur additiv tillverkning kan användas för att skapa färdiga produkter. <br /> <br /> Slutsatserna av detta examensarbete är att individuell kundanpassning av fästen och höljen är möjlig att genomföra genom att utnyttja additiv tillverkning. Det krävs att priserna för de tillverkade delarna sjunker till en rimlig nivå innan en sådan implementering anses rimlig. Att erbjuda kundanpassning av detta slag är inget som passar in i Axis Communications befintliga affärsplan, där en produktionsserie idag innebär tiotusentals produkter. En alternativ lösning kan därför vara att samarbeta med ett annat företag som tog ansvaret för den småskaliga produktionen och det administrativa ansvaret kring försäljningen av produkterna. The thesis objective is to create a concept where the customer gets the opportunity to decide, or change some of, the visual design of the casings, and/or the design of the mounting bracket for an Axis Communications’ surveillance camera. <br /> <br /> Customers have increased requirements for faster delivery and a growing need for customized products. In this thesis the possibilities with additive manufacturing is explored, to meet the customers’ increased requirements. As it is today additive manufacturing is primarily used for making prototypes, but there is a belief that the method can be used to manufacture end-use products and make more customer specific devices.<br /> <br /> To achieve this aim different manufacturing methods are evaluated and the selective laser sintering (SLS) is chosen to be the most suitable one. To get the direction of the project different customer scenarios are explored, sale alternatives are investigated and an exploration of potential installation environments is made. <br /> <br /> The main focus is to visualizing the concept by developing one mounting bracket and one casing for Axis’ cameras. These devices are created to show the abilities with a parametric design and how additive manufacturing can be used to create end-use products.<br /> <br /> The results show the possibilities to create customized products by using additive manufacturing. But the prices need to decrease before an application of this sort could be commercialised. https://lup.lub.lu.se/student-papers/record/3125590/file/3125593.pdf application/pdf 21299566 LU/LTH access 2012 eng Additive manufacturing Customer specified Surveillance Camera Axis Communications AB Technology and Engineering 3125590 2012-10-03T19:21:23+02:00 2012-10-08T10:35:18+02:00 2012-10-08T10:35:18+02:00

studentPublicationsH2 Henrik Sundberg author 3127242 Associate professor Rolf Larsson supervisor Division of Water Resources Engineering v1000225 department This study attempts to calculate the green blue and gray water footprint of the crop production of winter wheat and three derived winter wheat products: liquid fuel ethanol, wheat flour and macaroni. The calculations were done for Sweden for the period 2008-2010, covering an average of 80% of the annual winter wheat production. The south of Sweden was divided into 18 climate zones for which sufficient climatic data was available. The crop water use and requirements were then calculated for each of these zones using the CROPWAT model developed by the UN Food and Agriculture Organization, FAO. Other activities such as transportation, energy use and processing water were included in the study but combined these activities contribute to less than 1% of the water footprint of raw winter wheat production, referred to as the supply chain system. It is completely dominated by the cultivation component and the total water footprint is 875 m3 (59.4% green, 0.8% blue and 39.8% gray) per ton of wheat with a water content of 14%. Out of the supply chain system the cultivation component stands for 871 m3 (59.5% green, 0.6% blue and 39.9% gray) or about 99.5%. The result compares well to an earlier study by Mekkonen &amp; Hoekstra (2010a).<br /> In the case studies of refined winter wheat products the total water footprint is still dominated by the supply chain in general and the cultivation component within it specifically.<br /> The water footprint of wheat flour from winter wheat at the mill in Malmö is found to be 1.15 m3 (59.1% green 1.2% blue and 39.7% gray) per kg of flour out of which 99% is from the supply chain component.<br /> The water footprint of liquid fuel ethanol from the Agroetanol plant in Norrköping is calculated to 1 477 m3 (57.5% green, 4.2% blue and 38.3% gray) per m3 of ethanol, out of which the supply chain component is almost 95%, while the rest is mostly energy use in the form of bio fuel based steam production and electricity.<br /> The water footprint of the production of macaroni at the Ceralia factory in Järna is calculated to 1.30 m3 (57.7% green, 3.8% blue and 38.5% gray) per kg of macaroni. About 95% of this is from the supply chain component while the remaining 5% is mostly attributed to the energy used in the processes. Studien syftar till att beräkna det gröna, blå och grå vattenfotavtrycket vid odling och produktion av höstvete och tre fallstudier av höstvete-produkter; drivmedelsetanol, kärnvetemjöl och makaroner. Beräkningarna har utförts för Sverige under perioden 2008-2010 och täcker ungefär 80 % av den svenska produktionen av höstvete under de berörda åren. Södra Sverige delades in i 18 klimatzoner för vilka tillräckliga klimatdata fanns tillgängliga. Grödornas vattenanvändning och behov beräknades sedan för var och en av dessa zoner med hjälp av FN-organet FAOs (Food and Agriculture Organisation) vattenmodell CROPWAT. Andra aktiviteter i systemet som transport, energiproduktion och processvattenanvändning inkluderades, men bidrar med mindre än 1 % av vattenfotavtrycket sammanlagt i produktionen av höstvetekärnor. Denna del kallas supply-chain systemet i resten av rapporten.<br /> Supply-chain systemet domineras helt av odlingskomponenten och det totala vattenfotavtrycket är 875 m3 (59.4 % grön, 0.8 % blå och 39.8 % grå) per ton höstvetekärnor med 14 % vatteninnehåll. Av detta står odlingskomponenten för 871 m3 (59.5% grön, 0.6% blå och 39.9% grå) eller ungefär 99.5%. Resultatet kan med fördel jämföras med en tidigare studie av Mekkonen &amp; Hoekstra (2010a) I fallstudierna där vattenfotavtrycket av höstveteprodukter studeras dominerar supply-chain komponenten generellt, och odlingskomponenten inuti den, specifikt.<br /> Vattenfotavtrycket av kärnvetemjöl från kvarnen i Malmö beräknas till 1.15 m3 (59.1 % grön, 1.2 % blå och 39.7 % grå) per kg kärnvetemjöl. Ungefär 99 % av detta härrör från supply-chain systemet.<br /> Vattenfotavtrycket från drivmedelsetanol från Agroetanolfabriken i Norrköping beräknas till ungefär 1 477 m3 (57.5 % grön, 4.2 % blå och 38.3 % grå) per m3 etanol. Supply-chain komponenten står för nästan 95 % av detta, medan övriga avtrycket kommer från produktionen av bioenergi i form av ånga från E.on samt elektricitet.<br /> Makronerna som produceras vid Ceralias anläggning i Järna beräknas ha ett vattenfotavtryck på ca 1.30 m3 (57.7% grön, 3.8% blå och 38.5% grå) per kg makaroner. Ungefär 95% av detta härrör från supply-chain komponeneten, medan kvarvarande 5% mest kommer från produktionen av energi som används i tillverkningsprocessen. https://lup.lub.lu.se/student-papers/record/3127244/file/3127252.pdf application/pdf 2635204 no 2012 eng macaroni Lantmännen wheat flour liquid fuel ethanol winter wheat Water footprint Technology and Engineering 1101-9824 12/5004 Examiner: Linus Zhang 3127244 2012-10-08T13:51:25+02:00 2019-03-27T16:03:47+01:00 2012-10-09T21:14:58+02:00

This aim is secondary to the prime objective of the Directive, the increase in energy efficiency of energy-related products. By conducting ten in-depth interviews, the study investigates whether and in what form the Directive, which is to address 31 product groups, can contribute to innovations, potentially with resource efficiency improvements, referred to as eco-innovations. The analysis reveals the success of the Directive in cutting off the worst performing products from the market, highlights the Energy label as a stronger driver for innovation and discusses the current limitations of the Directive regarding the implementation of resource efficiency objectives. Recognizing that many issues are product-specific, the study is narrowed down to focus on electric motors, which account for high energy consumption in industry and demonstrate significant ecodesign improvement potential. The extension of the Directive electric motor group to possibly comprise permanent magnet motors is related to whether it could foster innovations capable of achieving resource efficiency improvements of rare earth elements. These materials, classified as critical in the EU, are able to achieve high energy densities in permanent magnets and can contribute to developing motors with higher energy efficiency classes. The case study uses a selection of innovation drivers integrated in Geels’ (2002) multi-level perspective for technological transitions to evaluate their influence on permanent magnet motor developments. Perceptions of permanent magnet motor manufacturer participants of the first preparatory study meeting are gathered through questionnaires for this purpose and interviews with material experts complement the case study. With regulatory standards being one of the most relevant innovation drivers, and the option to request design for recycling, the potential of the Directive to contribute to rare earth element resource efficiency improvements is indicated. https://lup.lub.lu.se/student-papers/record/3127648/file/3127913.pdf application/pdf 2980102 no 2012 eng Ecodesign Directive Innovation Resource Efficiency Rare Earth Elements Permanent Magnet Motors.

Computer consultancy firm Abou AB, in consultation with some of the municipalities, has concluded that a mobile application can be a possible channel when it comes to increasing the municipal engagement. Examples may be ranging from engagement in the question of whether to raise a new statue or not, to file a note about a burned down barbecue area. The question this thesis will attempt to answer is how such a municipal mobile application may be designed in order to bring the citizen closer to the municipality in order to get him or her more involved. Det finns önskemål från kommunens sida att öka det kommunala engagemanget hos medborgare i allmänhet och hos yngre medborgare i synnerhet. Detta kan vara allt från att engagera sig i upprättandet av en staty, till att anmäla en nedbrunnen grillplats.

Computer consultancy firm Abou AB, in consultation with some of the municipalities, has concluded that a mobile application can be a possible channel when it comes to increasing the municipal engagement. Examples may be ranging from engagement in the question of whether to raise a new statue or not, to file a note about a burned down barbecue area. The question this thesis will attempt to answer is how such a municipal mobile application may be designed in order to bring the citizen closer to the municipality in order to get him or her more involved.<br /> Purpose <br /> The purpose of this paper is to develop an understanding for the needs of the citizens, and based on those needs develop a concept for an application consisting of services and interaction design that will increase civic engagement. Method To understand the problem of what civic engagement is and what ingredients the concept consists of, literature studies have been carried out. Data collection has been largely conducted through interviews, focus group discussions and questionnaires. The material was analyzed using grounded theory. Inspiration has been drawn from some of today’s popular apps.<br /> Conclusion <br /> The design of a municipal mobile application with respect to interaction<br /> design should be easy to understand and if possible resemble applications<br /> that the user is familiar with. Services should focus on features that make it possible to give ones point of view, obtain information about the municipality and file reports in case something broken. The most important thing to remember is to enable two-way communication in order to make the citizen feel involved and dissemination of information in order to make the citizen feel enlightened. Det finns önskemål från kommunens sida att öka det kommunala engagemanget hos medborgare i allmänhet och hos yngre medborgare i synnerhet. Detta kan vara allt från att engagera sig i upprättandet av en staty, till att anmäla en nedbrunnen grillplats. Datakonsultföretaget Abou AB har i samråd med vissa kommuner kommit fram till att en mobil applikation kan vara en möjlig kanal när det kommer till att öka det kommunala engagemanget. Frågan detta examensarbete ska försöka besvara är hur en sådan kommunal mobilapplikation kan se ut för att föra medborgaren närmre kommunen i syfte att få denne mer engagerad. Syftet med detta examensarbete är att förstå medborgarnas behov för att därefter ta fram ett koncept till en applikation bestående av tjänster och en interaktionsdesign som ökar det medborgerliga engagemanget. För att sätta sig in i problematiken med vad medborgerligt engagemang är och vilka beståndsdelar begreppet består av har litteraturstudier genomförts. Datainsamling har till större delen utförts i form av intervjuer, fokusgruppsamtal och enkäter. Materialet har analyserats med hjälp av grundad teori. Dessutom har inspiration hämtats från applikationer som är populära idag. Utformningen av en kommunal mobilapplikation ska interaktionsdesignmässigt vara enkel att förstå och helst påminna om applikationer brukaren är van vid. Tjänstemässigt bör det finnas funktioner som gör det möjligt att lämna synpunkter, inhämta information om kommunen samt göra felanmälningar. Det viktigaste att tänka på är att möjliggöra tvåvägskommunikation för känslan av delaktighet och informationsspridning för upplysning. https://lup.lub.lu.se/student-papers/record/3128076/file/3128082.pdf application/pdf 2499682 LU/LTH access 2011 swe kommunapp app Digitalt medborgarskap mobilapplikation packaging logistics Technology and Engineering 3128076 2012-10-10T09:46:37+02:00 2012-10-10T11:55:02+02:00 2012-10-10T11:55:02+02:00

To provide a mean for stimulating students and researchers around the world for promotion of this new field, an annual world championship, Robocup, has been organized with start in 1997. During these competitions, the state-of-the-art technical achievements within Sensor Systems, Mechanics, Artificial Intelligence, Machine Learning and many other related fields are presented by the participants. The final goal is to create autonomous humanoids that can win a soccer match against humans by 2050.<br /> <br /> Computer Vision and Robotics are tightly bound together as vision is the most important part of the sensorimotor system enabling a robot to act in a dynamic environment. This includes recognizing landmarks for localization, obstacles for collision avoidance, and objects for manipulation. To go one step further in this direction, the challenge within Sony AIBO quadruped ERS-7 class for year 2004 was to recognize objects in different lighting conditions and to recognize and remember the position of newly detected landmarks. For this class of robots, the playground was a green carpet, surrounded by white walls. Two nets and four beacons in four different two-color combinations were the only permanent landmarks.<br /> <br /> The object recognition module was decided only to be designed for rendering the task of recognition of all predetermined as well as unknown landmarks on and around the field given a set of image frames containing shapes presented as color blobs. Most importantly, the module should be designed in a way that it could recognize the regular objects independent of the lighting conditions and calculate the angle and distance to each one as well as the confidence for the calculated results. The outcome was thereafter to be saved in a common space for the other modules to use and act upon.<br /> <br /> As the most challenging object to recognize and estimate the distance and view angle to is the ball, the step by step approache to a successful solution is presented in the report. The next subject mostly discussed is how to recognize the nets, where several factors affect the precision and confidence. Other subjects as filtering the information, how to consider the pose of the head, and how to use a voting system for raising the confidence are discussed thoroughly. Also some pros and cons of each method are looked at. For the reasons discussed throughout the text, the recognition was primarily based on color verification and not the shape of the blobs. The module was implemented in Matlab for unit test and to verify the theories and later on implemented, assembled, and compiled in C++ for the final run.<br /> <br /> Although individual tests in the lab environment showed on a successful module in recognizing objects on and around the field, lack of a consistent color segmentation table resulted in a poor quality of recognition in variable lighting conditions during the competitions. Nevertheless, the module is reusable as the methods are as general as possible to fit different platforms with diverse frame rates and dimensions.<br /> <br /> Regardless of the outcome, the thesis work presented in this report lays a ground for a vision module that can perform the task of recognition of known and unknown objects. In particular, it reports on the methodology used for recognition of objects with estimation of their distances and angles to the AIBO, for which a software vision module is implemented. The contribution of this thesis is the methodology for detection of the peripheral of the ball blob, using a voting system, an attempt to merge blobs, specially for finding the rectangular shapes and correct estimation of their sizes, and an investigation about using rule based verification of the objects, methods that had not been used before by any teams in previous years. https://lup.lub.lu.se/student-papers/record/3129335/file/3129337.pdf application/pdf 8833752 no 2010 eng Robocup Robotics Computer Vision Legged Robots Computer Science Technology and Engineering 1650-2884 LU-CS-EX: 2010-33 3129335 2012-10-14T23:43:24+02:00 2015-02-10T11:17:46+01:00 2012-10-30T23:16:59+01:00

studentPublicationsH2 Petra Andersson author Associate Professor Åsa Ek supervisor Ergonomics and Aerosol Technology v1000237 department Exposure to vibrations from tools and machines used in construction work can induce damages to the human body. Oscillations around a fix point with a certain direction, frequency and magnitude describe the phenomenon vibrations. Their influence is generally expressed as acceleration [m/s2]. Furthermore, vibrations are separated in two categories; hand‐arm vibrations or whole body vibrations. Exposure to vibrations can lead to physical pain in<br /> different ways. One of the most frequent symptoms of hand‐arm vibration syndrome (HAVS)is commonly known as white fingers. This symptom generally involves whitened extremities,<br /> pain in arms and fingers and degradation in mobility and function when it comes to finer motor skills.<br /> <br /> The Swedish Work Environment Authority, Arbetsmiljöverket, introduced new guidelines on the topic of vibrations in 2005; AFS 2005:15. They refer to the responsibilities and rights of<br /> employers and employees. Also, they are aligned with the 2002/44/EG directive of the European Union. According to the guidelines, the employer should account for the estimation<br /> of exposure to vibrations on work sites where this is a present risk. In 2011, the Authority reported an unsatisfactory effort on prevention of occupational injuries due to vibrations. Similarly, Occupational and Environmental Medicine at Skåne University Hospital (Lund)reacted on not seeing any decrease in the frequency of injuries derived from the construction industry. Despite new guidelines, the number of workers reporting occupational injuries due to exposure to vibrations has not decreased. In order to investigate the reason to why the construction industry has not been affected by the new guidelines, and how this goal can be reached, a part of the Swedish contractor Skanska has been studied.<br /> <br /> This study mainly consisted of interviews at a number of construction sites of civil works in southern Sweden. A total of 10 site supervisors and 21 construction workers were<br /> interviewed. The interviews focused on exposure to and experiences of vibrations and related injuries and on information on daily work routines. After a compilation of the first block of interviews, two more profound interviews were held with professionals at higher positions in<br /> the Skanska organization.<br /> <br /> The interviews with site supervisors demonstrated a lack in knowledge when it comes to estimating the magnitude of exposure to vibrations at the construction sites. Of the 21<br /> interviewed construction workers, 11 people might belong to a risk group of developing HAVS. They either suffered from suspected symptoms already, or suffered from other injuries<br /> that in combination with exposure to vibrations might lead to HAVS development. Incorporating the Work Environment Authority’s directions has not been accomplished,<br /> partly due to the characteristics of the actual directions and the motivation of Skanska as a whole to adjust to them. Another strong influencer is the psychosocial work environment of the construction industry; characterized by a segregated hierarchy and a homogeneous work force.<br /> <br /> Several actions have been suggested to improve the preventive health and safety work at Skanska. The risk of vibration injuries could be better prevented by introducing a manual for<br /> daily vibration exposure assessment, by further educating the employees on the physical risks of exposure to vibrations and by tagging the vibrating tools and machines used on site. https://lup.lub.lu.se/student-papers/record/3130799/file/3130810.pdf application/pdf 2660452 LU/LTH access 2012 swe Vibrationsskada byggindustri väg‐ och anläggning arbetsmiljö och säkerhet Technology and Engineering 3130799 2012-10-18T13:53:44+02:00 2012-10-22T12:25:15+02:00 2012-10-22T12:25:15+02:00

We have focused our work on solving this with a stand-alone complementary building which contains all the critical functions a dwelling should have. To facilitate and make the investment more realistic the building should be constructed so it is permit-free in terms of building permits. We started with a research of the building regulations and the rules of permit-free complementary buildings, so-called friggebodar. After that we did a survey of the existing solutions of friggebodar, compact living and building materials. Based on the survey and our own demands we produced two different layouts. To show the huge amount of different solutions to this problem one layout was quite easy and basic and the other one was fairly complex with more advanced and modern solutions. We chose high requirements on energy performance but to maximise the floor area we had to make the walls thinner than usual without affecting the performance. To make that possible we had to choose modern and expensive materials and that resulted in 32% increased area. To make sure our constructions (walls, roof and foundation) could stand the loads from the building and snow etc. we did calculations accordingly to the Eurocode standard. When we were sure it did we used the results from the calculations to make both architectural and construction drawings. Finally we used the drawings to calculate the amount of material we need and how much the cost of it will be. The price of all the materials need to build and furnish the building is 120 950 SEK but it does not take into account the cost of actually building it or the installation cost for plumbing and electricity. Keywords: Extra room, one-and two-family houses, friggebod, complementary building, stand-alone. https://lup.lub.lu.se/student-papers/record/3130980/file/8961520.pdf application/pdf 2667879 no 2012 swe extrarum bygglovsfritt en-och tvåbostadshus friggebod komplementbyggnad fristående Technology and Engineering 3130980 2012-10-17T00:00:00+02:00 2018-10-18T10:22:42+02:00 2012-10-19T00:00:00+02:00

Natural forms possess exceptional rigidity<br /> and use minimum materials to maximum structural advantage. To quote Makowski,<br /> &quot;Natural forms act in the direction of minimum effort&quot;. Man has not been slow in copying<br /> these examples drawn from Nature. The main structural aim which drives the use of this construction system is to use the least material possible to achieve a lightweight structure and at the same time have good characteristics of rigidity and restricted deformation. The proposed construction technology can provide ample opportunity for structural engineering; it lends itself to the creation both of bridges of considerable importance and of three-dimensional structures for covering large areas without the use of bracing elements.<br /> Nowadays, the development and diffusion of timber construction systems demonstrate<br /> their validity and competitiveness especially in the construction of roofs and bridges, even with long spans. This has given rise to the idea to use timber even for the space frame technology. The research will be directed to explore the possible applications of the system, initially scheduled for tubular steel structures, in the field of wooden construction. Always used as a structural material in the construction of frames, floors, roofs and bridges, timber material has found high regard in modern civil constructions. In the building industry we often talk about sustainability, energy conservation and the need to relate the constructions with the hosting environment, from this perspective timber has been greatly revalued rediscovering the qualities well-known in traditional building regarding the excellent mechanical characteristics, the simplicity and the versatility for esthetic and modern architectural use. The idea of applying this technology to laminated wood structures was proposed by ing. Arne Emilsson of the engineering company LIMTRÄTEKNIK AB which boasts<br /> a long career in the design of timber structures in Sweden and always looks for new applications of the material in modern buildings. The proposed research project is inserted<br /> harmonically in a larger context that sees the Università degli studi di Trento and the Lunds Tekniska Högskola busy with their own research institutes and associated companies in the development, use and promotion of wood as a building material. The research is directed to explore the possible applications of the space frames system in the field of wooden construction, the proposed construction technology can provide ample opportunity even for timber engineering. The aim of the thesis is to prove the possible application of the timber material considering that the design of wood structures is very complex and requires detailed theoretical knowledge accompanied by the intuition and the ability which comes from an understanding of the critical points of the structures. The work is organized into several parts that try to consider all the thematic relating to the design of the specific construction technology and the material particularities.<br /> Part I describes in general the timber space frames system; it elencates the description,<br /> the development, the components and the advantages of the technology. It also<br /> introduces and correlates the use of timber material in the space frames system listing<br /> any possible issue related.<br /> Part II is about the development of the connection system for transferring the axial<br /> stresses from the member to the node. The connections must be able to resist cyclic<br /> stresses, exhibiting a good ductile behavior, allowing, among other things, to increase<br /> the general robustness of the construction. Different technologies like screws inclined<br /> 45° to the grain and pre-stressed bolts working in shear are mentioned for an advantageous<br /> application in the truss system.<br /> Part III treats a specific case study of a space frame court mentioned in the book<br /> «Analysis, design and construction of Steel space frames» (G. S. Ramaswamy et al. 2002)<br /> [1] . The design of the same construction in glued laminated timber instead of high<br /> resistance steel, using the same geometry and loads demostrates the complete applicability<br /> of the topics treated in the previous parts. The design is performed according to<br /> the new regulations checking the resistance of any element at the ultimate limit state.<br /> The deformation of the connection with preloades bolts and the deflection of the court<br /> are checked to be within the limits recommended. https://lup.lub.lu.se/student-papers/record/3131142/file/3131144.pdf application/pdf 5175035 no 2012 eng Technology and Engineering 0349-4969 TVBK-5218 3131142 2012-10-19T12:46:30+02:00 2012-10-24T14:59:01+02:00 2012-10-24T14:56:29+02:00

The bridge is compared with an existing composite bridge built in Kalix, Sweden. Initially both bridge solutions are presented and some detail descriptions is presented for the bridge with the glulam deck. A short description of the finite element method is given together with the main equations for the finite element model for plates. The basics on how to build up a finite element model in SAP 2000 is also presented. A main goal with this report is to study how the risk for lateral torsional buckling can be reduced by using a lighter bridge deck. This is done by first deciding what kind of loads the bridge is subjected to. Then the critical lateral torsional buckling moment is calculated for different spacing between the cross girders. Hand calculations are compared to a finite element model in SAP 2000 and the minimum number of cross girders is calculated. The results are then compared with a finite element model in SAP 2000. It´s also checked how the risk for lateral torsional buckling is reduced when the bridge deck is attached. This is performed by attaching springs between main girders and bridge deck in the model in SAP 2000. The springs represent screws and different stiffness is applied to these screws. Analysis is made and the total stiffness of the bridge is examined. The bridge is also checked in the serviceability state. It is shown that the vertical deflection is<br /> bigger than accepted. A suggestion to decrease the deflection is to build the bridge with a small vertical curvature. Results from the analysis shows that the number of cross girders can be reduced by half. It is<br /> also shown that a distance of 160 mm is required between the screws with a diameter of 12 mm to achieve sufficient total stiffness of the bridge deck. This is the screws that attach the main girders to the bridge deck.<br /> In the report an overviewing economic calculation is also done. The report shows that a big cost in the glulam alternatives is the bridge deck. However the alternatives with the glulam deck can be built faster since there is no time for concrete hardening. This can save a lot of<br /> money in labor costs. https://lup.lub.lu.se/student-papers/record/3132377/file/3132380.pdf application/pdf 2537042 no 2012 swe Samverkansbro vippning finita elementanalys SAP 2000 brottgränstillstånd bruksgränstillstånd skjuvbuckling spänningskapacitet Technology and Engineering 0349-4969 TVBK-5213 https://lup.lub.lu.se/student-papers/record/3132377/file/3241677.pdf application/pdf no 3132377 2012-10-24T14:21:25+02:00 2012-12-13T10:05:59+01:00 2012-10-24T14:55:44+02:00

Compared to a rope bridge, the stress ribbon bridge has a reinforced concrete slab. This has bending rigidity and significant weight, which eliminates the flexibility that is typical of rope bridges and provides stability and rigidity such that the bridge also can be used for vehicular traffic.<br /> The current report is an introduction to the bridge type. Its appearance, construction, production, use, typical dimensions, static and dynamic operation are briefly described. The principles, equations and criteria for a preliminary design are also given. Depending on the load type, deformations and stresses can be calculated analytically or numerically<br /> using the finite element method. Both methods are used in an example of preliminary design. Diagrams show how various design parameters can affect the function of a bridge with a span of 80 m. When designing a stress ribbon bridge there are different stages in construction and usage<br /> time. This report takes into account five different stages:<br /> - Stage 0: Installation of bearing cables with dead load of separated concrete segments.<br /> - Stage 1: The concrete segments cast together, applying post-tension force and then assemble all the dead load from the non-structural parts.<br /> -Stage 2: Official opening of the bridge. This means the introduction of live load and also temperature variation.<br /> - Stage 31: Long-term effects add to the analysis of Stage 1.<br /> - Stage 32: The final stage involves a modification of the quantities at Stage 2 and introducing the time-dependent effects.<br /> <br /> The preliminary calculations in this report suggest that stress ribbon bridges may be of special interest for pedestrian and bicycle bridges with long spans. Vibration frequency and bending moments in the bridge deck with live load along only half of the bridge appear to be critical in the design. Parametric studies showed that low or no post-tension<br /> force reduces the need for reinforcement and bearing for the bridge in the form of hinged fixed bearing can be better then fixed rigid bearing. https://lup.lub.lu.se/student-papers/record/3132390/file/3132393.pdf application/pdf 3165791 no 2012 swe Stress ribbon bridge Pedestrian bridge Curved beam Suspension structure Cable structure Post-tension.

The data is collected from 45 small towns and communities in peri-urban areas in the Volta, Ashanti and Northern region. I have used correlation analysis and multiple regression analysis to derive cost functions for small town water systems and for the components in a water system. The aim is to derive functions for the total capital expenditure of a small town water system and for the fixed assets: mechanized borehole, water reservoir, pipe work and stand post. The resulting functions are created both for initial use before planning a new system and after having done the first design of a water system. The results are presented as eight functions, representing the total capital expenditure for a water system and capital expenditure for the assets water reservoirs, pipework and stand posts. The data was insufficient in deriving a function for mechanized boreholes. Key parameters for validating the functions are presented in relation to the functions. Explaining variables that were frequently used are design population, length of pipeline, volume of reservoir and dummy variables for region (location). The functions vary in accuracy with an explanation coefficient R2 varying from 0.42 to 0.88. The functions that have explaining variables, requiring a first investigation at place of the intended water system, are particularly interesting to use in forecasting capital expenditure. Rapporten är en sammanställning av ett kandidatarbete, huvudsakligen utförd som en ”Minor Field Study” i Kumasi, Ghana och i samarbete med WASHCost. WASHCost är ett pågående internationellt forskningsprojekt med holländska IRC som initiativtagare. Genom att använda data, insamlad av forskare från WASHCost i Ghana har jag undersökt vilka kostnadsdrivare som kan användas för att förutsäga kostnaderna vid nybyggnation av ett dricksvattensystem med grundvattenteknik för mindre orter med populationer under 20 000 invånare. Databasen täcker 45 tätorter ifrån tre ghananska regioner; Volta, Ashanti och Norra regionen. Huvudmålet med studien har varit att skapa en kostnadsfunktion för att i ett tidigt skede kunna få en uppfattning om de totala investeringskostnaderna vid nybyggnation av ett drickvattensystem. Sekundärt har funktioner skapats för att förutsäga kostnaderna för följande ingående komponenter i ett ghananskt vattennät:Borrhål med automatisk pump, vattenreservoarer, rörledningsnät och vattenposter. Till min hjälp för att skapa relevanta funktioner har jag använt mig av sambandsanalys och multipel regression analys med olika modellalternativ. Dataunderlaget innehåll inte tillräckligt med information för att kunna skapa någon funktion för borrhålen. I resultaten redovisas åtta olika funktioner, varav två beskriver den totala investeringskostnaden. Av funktionerna är fem skapade efter linjära modeller och tre efter exponentiella. De vanligaste förekommande kostnadsdrivarna, alltså förklarande variablerna, är: i vilken region vattensystemet är lokaliserat, den dimensionerande populationen, den totala rörlängden och vattenreservoarens volym. I samband med resultaten presenteras även nyckelvärden för att kunna bedöma funktionernas tillförlitlighet. Förklaringsgraden, R2, för funktionerna varierar mellan 0.42-0.88, vilket ger en stor variation i tillförlitlighet. De mest intressanta funktionerna är de som kallas för ”first function” och kräver en första utredning för det tilltänkta vattensystemet, men ger istället en bättre precision i att förutsätta kostnaderna. https://lup.lub.lu.se/student-papers/record/3157946/file/3157954.pdf application/pdf 2514845 no 2012 eng Ghana small town water system cost function capital expenditure multiple regression analysis Mathematics and Statistics Technology and Engineering 3157946 2012-10-25T14:31:07+02:00 2012-10-25T15:36:35+02:00 2012-10-25T15:36:35+02:00

In the current situation, many of the major players use BIM both in the design and production phase. What remains is to explore is how BIM can be used in property management.<br /> Purpose: The purpose of this study is to find out which information the contractor must put in the BIM model so that the property managers can get an added value.<br /> Method: The study was conducted as a case study and interviews were conducted with property managers. The interview method has been open-targeted and based on the results; a proposal has been prepared for the introduction of BIM in the management phase.<br /> Conclusion: The knowledge of BIM among property managers in the current situation is very limited. Managers are generally positive about the introduction to BIM in the management phase. In order to successfully and efficiently implement BIM in the management phase, it is up to contractors, developers and others knowledgeable in the field to develop and promote short-term benefits of BIM in the management phase.

For the two case studies, there is a portal<br /> that manages the information. The contractor provides documents that the provider needs to submit quotation for a project purchase. All the handling of documents is made in the portal but the quote is sent by e-mail back to the contractor. For a purchase by call-offs against a contract, it is the provider that provide information through the portal, so that the buyer easily can make their purchases. The processes work well but would be better if all the information were gathered in the portal.<br /> Today, there is no general method for the delivery process. Delivery notification will take place days before the delivery, usually by telephone and when the goods arrive, a visual inspection of the received goods is made so that everything consistent with the packing slip, and that nothing is damaged. By conducting a precisely and documented reception, the information can be stored and used for after- following activities in the process and automatic controls can be implemented. To get a more conducted documentation it is required that the material is id-marked. Identification labels will also increase the possibility to easier follow the material to the workplace, resulting in better communication between the parties.<br /> Electronic invoices are becoming more common but still, many businesses receive paper invoices and must scan them. If the invoice is received fully electronic checks can be performed automatically on the information in an integrated system. Such system would also contain information on follow-ups. https://lup.lub.lu.se/student-papers/record/3158109/file/3159818 application/pdf 1419990 no 2011 swe Technology and Engineering 10/5419 3158109 2012-10-26T10:53:01+02:00 2012-10-31T14:31:42+01:00 2012-10-31T14:31:42+01:00

The field-of-use for the current stretcher is in hospital- and homecare, although other competitive scoop stretchers are used for ambulance emergency care. For this reason, the possibility to extend the target group is investigated.<br /> <br /> Firstly, a comprehensive study, i.a. through study visits, was performed to establish customer needs and limitations for a new scoop stretcher. From these a number of specifications were established in order to evaluate and compare the performance of existing scoop stretchers on the market. These specifications were later used to evaluate the final concept.<br /> <br /> In the next step a list of subfunctions for the scoop stretcher was identified and for each subfunction a number of concepts were generated. Both the subfunctions and concepts main purpose is to satisfy the user needs. The concepts were screened to sort out less promising ideas, and the remaining was combined. These combinations were scored as guidance for a final choice of concepts. During the generation of concepts it was established that composite material was the most suitable candidate for the supporting areas of the stretcher. Therefore a more complex approach to the material aspect was used in the further development of the concepts.<br /> <br /> Members of the target group were then revisited in order to get feedback on the chosen combination of concepts. A simple prototype in wood was built to test the ergonomics of the stretcher. How to adapt the stretcher for a human was analysed in order to obtain dimensions for the CAD. Further development of the components resulted in CAD-models that could be analysed in FEM to determine the performance of the stretcher. In this stage manufacturers were contacted in order to make sure that the design was realizable.<br /> <br /> In the final step the FEM-analyses was performed and the result indicates that the established criteria was met. The new scoop stretcher has supporting surfaces in carbonfiber-epoxy-laminate with a new improved coupling mechanism and it is length-adjustable by two telescopic aluminium bars attached underneath the composite parts. The total weight is reduced from 9.4 kg to 7.8 kg and the safe-working-load is increased from 160 kg to 272 kg. It is also adapted for wider and taller patients than the current scoop stretcher. Other aspects are also improved such as ergonomics, hygiene and center of gravity adaption. https://lup.lub.lu.se/student-papers/record/3158730/file/3158734.pdf application/pdf 6271121 yes 2011 eng scoop stretcher product development FEM composite bedridden patients Technology and Engineering 3158730 2012-10-29T12:03:42+01:00 2013-01-07T08:23:08+01:00 2013-01-07T08:23:08+01:00

The task is to develop a system to mount a bright trim on a vehicles bodyside. A bright trim is a polished metal trim that is fitted around the windows of a vehicle for aesthetical reasons. The conventional method in VCC is to mount the bright trim on the doors and this generates a number of problems when it comes to variation.<br /> <br /> Doors are movable parts that are mounted on the vehicle body with a hinge, thus the doors position has a relatively large variation. If the bright trim is mounted on the door it has an internal variation relative to the door, this ads to the door variation and gives the system properties that are sensitive to variation. Because the bright trim on the front and rear door are lined up and the bright trim has a polished and eye-catching surface the variation is clearly visible.<br /> <br /> To overcome these difficulties one solution is to mount the bright trim on the bodyside in one piece. This erases the splits in the bright trim and therefore the system is not as sensitive to the doors variation.<br /> <br /> The prerequisites are mostly determined from interviews with employees in VCC and research based on the knowledge from the education at LTH.<br /> <br /> After the research, concept generation began with the prerequisites in mind. The chosen concept was developed especially with shape and mounting method to fit the narrow section in the quarter glass area on VCC vehicles. The bright trim is mounted in Y-direction instead of Z-direction that is the method used by other car manufacturers using similar solutions.<br /> <br /> To fasten the bright trim to the body, a method is used that has the advantage that it only takes up 2 mm on the inside of the cant rail. This gives the opportunity to design the reinforcements on the inside of the cant rail more freely. Principally, a plastic clip with bayonet clutch properties allows this, it is placed in a specially shaped hole and is then rotated 135°. Barbs keep the bright trim in place.<br /> <br /> Another function of the bright trim than aesthetics is that it also functions as a drip moulding to prevent rainwater to run over the roof of the vehicle when the doors are open and contaminating the seats. In the bright trim a rubber moulding is fitted that leads the water away from the door openings.<br /> <br /> The solution is verified with computer visualisations and simulations and physical tests. https://lup.lub.lu.se/student-papers/record/3158772/file/3158774.pdf application/pdf 3611546 yes 2011 eng Automotive car exterior trim fastener Technology and Engineering ISRN LUTMDN/TMKT 10/5412 SE 3158772 2012-10-29T12:26:59+01:00 2013-01-07T08:24:04+01:00 2013-01-07T08:24:04+01:00

The water industry would be able to improve the quality of distributed drinking water if spatial and temporal variations of BDOC could be mapped in the distribution system. The aim of this study is to design a method to measure the BDOC concentrations in the drinking water produced and distributed by the water treatment plant Ringsjöverket. <br /> Two recirculating batch reactors were designed and packed with biologically active sand. Drinking water samples were collected at pump stations along the water distribution network that stretches from Stehag to Örby. The samples were recirculated in the bioreactors for approximately one week. COD and UV absorbance of the recirculated water was analyzed at different time intervals to be able to analyze the change in DOC concentrations and chemical composition. TOC concentrations in the water of the bioreactors were analyzed at VA SYD water laboratory. Before analysis all water samples were filtered to separate POC from the DOC pool (Kaplan and Newbold, 1995). The only available chemical analysis of dissolved organic carbon at Ringsjöverket was the CODMn method. To translate the COD values into DOC values a ratio (TOC/COD) was analyzed and determined to be 1.92. <br /> <br /> The results show a general trend of higher outlet values of COD than inlet COD values. These results indicate that the fraction of biodegradable organic carbon dissolved in water could not be determined in the BDOC bioassay designed at Ringsjöverket since no or few reduced values of COD were observed. The probable reason for the increase of COD when the water samples were recirculated was that the bioactive sand was leaking organic matter. The biofilm probably needed more time to adapt to the organic loading and chemical composition of the water samples to reach a dynamic equilibrium with a net reduction of BDOC. Furthermore, it is possible that the BDOC concentrations in the distributed drinking water from Ringsjöverket are so low that changes in concentration cannot be measured with this method. <br /> The results of the UV analysis show a general trend of increasing UV absorbance with time as the sampled water was recirculated in the bioreactor. One explanation for the increase in aromatic DOC is that the chemical composition in the water samples was altered by bacterial metabolism. Further studies are needed to establish such a correlation. Another possible explanation to the increase of aromatic DOC in the recirculated water is that the bioactive sand released aromatic organic matter.<br /> As a conclusion, further studies are needed to provide Ringsjöverket with reliable and fast information about the BDOC concentrations in the water distribution system. https://lup.lub.lu.se/student-papers/record/3159617/file/3159618.pdf application/pdf 1535526 LU/LTH access 2012 eng water treatment plant drinking water biodegradable dissolved organic carbon COD TOC UV absorbance bacterial growth water distribution system biofilm bacth reactor Technology and Engineering 1101-9824 TVVR 12/4004 3159617 2012-10-30T20:41:26+01:00 2012-11-15T17:33:11+01:00 2012-11-15T17:33:11+01:00

Because of this, it is important to consider both the positive and the negative aspects regarding the phenomenon. Furthermore it is vital to analyze how companies utilize their BI systems and how it affects them. With this paper we strive to attain a deeper understanding of the practical implications of a BI system. In order to achieve this goal we developed our literature review where we found five key aspects of BI systems; Strategy, Economy, Reliable data and consolidation, Scalability and Flexibility and Security. Furthermore, we based the interview guide on those five aspects we previously identified and conducted four interviews with four different companies. Afterwards we compared the reviewed theory with the empirical results from our interviews to investigate similarities and differences. It showed that all of the companies were familiar with these five aspects and all of the companies argued that thanks to the BI system, they could consolidate all of their data and instead of using different systems to access data, they could easily connect to the BI system to instantly retrieve all useful information. Furthermore all companies emphasized that the BI system secured the reliability of the company data. Essentially, all of the companies stated that they were very satisfied with having a BI system within the organization. Despite the fact that it was to some extent economically demanding to implement the BI system, it was worth it in the long run. https://lup.lub.lu.se/student-papers/record/3159795/file/3159802.pdf application/pdf 1044826 no 2012 eng Business Intelligence systems Strategy Economy Reliable data Consolidation Security Scalability Flexibility Technology and Engineering 3159795 2012-10-31T13:44:35+01:00 2012-11-16T14:38:13+01:00 2012-11-16T14:38:13+01:00

Weight optimization is important since it provides a structure that can carry the applied loads in addition to fulfilling the structural requirements. In this project, a Matlab-algorithm has been developed to find the optimum design of steel portal frames according to “Eurocode 3: Design of steel structures” with regard to the weight. To get the final design of the frame, some inputs have to be specified by the user such as the material, the coordinates, the loads and the distribution pattern of the bracings.<br /> The algorithm goes through three essential steps before getting the optimal frame:<br /> - Analyzing the frame with help of CALFEM-toolbox: In this step, the frame is geometric nonlinearly analyzed due to certain load combination according to the Ultimate Limit State (ULS) and Serviceability Limit State (SLS) criterion. The internal forces and the displacement established and the axial force diagram, shear force diagram, bending<br /> moment diagram and the deformed shape of the frame to be calculated and plotted.<br /> - Checking the capacity of the frame according to Eurocode: Some constraints with regard to EC should not be violated. These checks may refer to the frame capacity, checking the capacity against the risk of buckling and the deformations which should not be exceed the Serviceability Limit State (SLS) limitations.<br /> - Finding the optimal design of the frame using Genetic Algorithm optimization method: Genetic Algorithm (GA) is an iterative searching method based on the evolution of species’ principle. The algorithm repeat the two steps above every iteration cycle trying to find the best design that has the minimum weight without violating the limitations. Since it is an iterative process, the time required to find the optimum design<br /> depends on some factors such as the speed of the computer, the number of variables the size of frame mesh etc.<br /> <br /> The project ends with some testing examples in which a frame with width span of 20 m, and a height of 6.5 m and uniformly distributed loads as snow loads are acting on the roof of the frame. In these examples, the algorithm has been tested to compare the design that have been got in case of fully braced frame, unbraced and by letting the algorithm to find the optimal number and position of the bracings along the frame. Another comparison has been done to see the difference of the design in case of absence /existing of the deformation limitations. https://lup.lub.lu.se/student-papers/record/3159822/file/3159828.pdf application/pdf 5800634 no 2012 eng Technology and Engineering 0349-4969 TVBK-5215 3159822 2012-10-31T14:19:56+01:00 2012-10-31T15:28:54+01:00 2012-10-31T15:28:54+01:00

This is mainly due to not having mastered the timber construction to the same extent as steel and concrete. Nowdays the interest in timber bridges have increased and the technical solutions have been greatly developed in the last 15 years. The purpose of this study is to provide an insight of how a design of an arch bridge in timber is according to Eurocode can be done. For the report the design will be checked with hand calculations and with commercial FEM software, SAP2000. When hand calculations have been too time consuming or not possible for the authors to implement FEM have been used for the design values.<br /> The case study is based on an existing arch bridge with a stresslaminated timber deck in Norway which was designed by the old Norweigan standards. The results from the hand calculations gave a lower strength compared to methods based on the finite element method. The difference between the two methods were not very large, hand calculation are about 20 % lower than the methods which were calculated by FEM. For out of plane buckling the bracing stiffnes at the attachment points have a great influense on the strength of the arch. In reality the hinged attachment points is not rigid at the transverse direction and should be considered when designing the bridge. The buckling load can vary between 1 and 45 MN but make the greatest contribution before the out of the plane stiffness reaches 10000 N/mm.<br /> Bending stresses in the transverse direction is a big problem for the deck. The material utilization of the deck was calculated to 565 % of the recommended pre-stress level of 1 MPa. Both compression and tension are the same in the deck but with opposite signs, this may be because the modeling is done with shell elements.<br /> When comparising the authors&#39; plate model with Ekström in Chap. 9.6.1 it can be seen that the solid elements provide a different stressdistributions at the top and bottom of the deck. The tensile stresses are less than the compressive stresses in the solid plate member, this is due to the maximum compression stresses that are obtained directly under the load which generates an &quot;disrupted zone&quot; of the stresses. When modeling account, therefor no accurate representation of the results are obtained when modelizing the plate member in SAP2000.<br /> Although the calculations shows that the bridge lacks strength at some points, we must not forget that this is an existing functional bridge in Norway. The bridge is designed for old standards according to Norwegian regulations and has probably passed the requirements. This is a sign that the new Eurocode is much more stricter than previous standards. https://lup.lub.lu.se/student-papers/record/3159835/file/3159836.pdf application/pdf 5160904 no 2012 swe Arch bridge timber bridge stress laminated timber deck FEM hand calculation plate model shell element frame element & solid element.

Most of the research performed on these structures has focused on systems in which wet concrete is cast on top of timber beams with mounted connectors. Recently investigations on composite systems were performed at Luleå University of Technology in Sweden, in which the concrete slab is prefabricated off-site with the connectors already embedded and then connected on-site to the timber<br /> joists. Similar studies have been carried out also on timber-concrete composite structures with prefabricated FRC slabs at Lund University in Sweden. Two kinds of shear connectors were incorporated in the prefabricated FRC concrete slabs. These last systems can be considered globally as partially prefabricated structures because only the slabs were cast off-site with already inserted shear connectors and then the<br /> connection with the timber beams is done on the building site. An innovative composite system for floor applications is presented in this thesis. The entire structure is prefabricated off-side, transported and direct mounted to the building on site, that can be seen as full prefabricated structures. Noticeable benefits of a full prefabricated structure are that the moving work from the building site to the workshop reduces construction costs, is more simple and fast of manufacture and erect, and of sure, has better quality, that means more durability.<br /> Self-tapping full-threaded screws to connect concrete slabs to timber beam were used. Dimensions of the composite beams and the spacing between the screws has been chosen by discussing different FE model in order to reach the optimal solution. The experimental campaign included: <br /> (i) two short-time bending tests carried out on two dierent full-scale specimens, <br /> (ii) dynamic tests conducted on one full-scale specimen, <br /> (iii) long-time bending test carried out on one full-scale specimen, <br /> (iv) compression tests on three cubes of concrete, <br /> (v) nine withdrawal tests of the screws with different depth in the concrete. <br /> The results of the experimental tests show that the composite beams have a very high level of resistance and stiffness and also allow to reach a high degree of efficiency.<br /> Last, comparisons between FE results, analytical calculations and experimental values have been performed and from them it can be concluded that FE model and theoretical calculations well interpret the behavior of the composite structure and provide reliable results. https://lup.lub.lu.se/student-papers/record/3159841/file/3159856.pdf application/pdf 30726670 no 2012 eng Technology and Engineering 0349-4969 TVBK-5212 3159841 2012-10-31T14:41:58+01:00 2012-10-31T15:27:57+01:00 2012-10-31T15:27:57+01:00

This makes it more interesting in looking in to new ways of constructing timber bridges. Most timber bridges for road traffic are using an arch with a hanging deck suspended from the arch using vertical hangers. This master thesis has looked at the possibility of using a system (developed for steel arch bridges) that is using inclined hangers, “the network arch”. This system has proven to greatly lessen the bending moment in the arch for steel arch bridges.<br /> A parametric study has been performed to decide the influence of the different parameters of the bridge. The study was made using a finite element program to calculate different influence lines. These influence lines have then been the basis of the study. The study showed that by changing the stiffness of the arch and hangers the influence lines for the designing bending moment could be changed and the point for the critical section could be moved.<br /> The study has also showed that the problem with relaxing hangers was bigger than anticipated. Hanger relaxation is a problem for network arches and is due to the fact that a partial load of the bridge will deform the arch in a sideways movement. This movement will decrease the distance between the nodes for some of the hangers making them “to long” to take any load.<br /> The study was made on a hanger constellation using the same angle for all of the hangers. It was proven that the problem with relaxation was biggest close to the supports. This proved that another hanger constellation using a constant or parabolic change of hanger inclination would probably lessen the risk of relaxing hangers.<br /> The feasibility of the system was then tested by designing a 50 m long and 10 m wide network arch bridge with a hanger inclination of 55 degrees. A reference bridge with a more conventional design with vertical hangers has also been designed.<br /> This design showed that by using the network arch system the bending moment that was achieved was almost nine times smaller and the cross-section of the arch was almost half the size. The lessening of the bending moment also had a great impact on the tension perpendicular to the grain of the arch, a load that is a big problem for arches especially when using the Eurocode design standards. https://lup.lub.lu.se/student-papers/record/3159858/file/3159862.pdf application/pdf 2428573 no 2012 eng Technology and Engineering 0349-4969 TVBK-5211 3159858 2012-10-31T14:53:52+01:00 2012-10-31T15:26:49+01:00 2012-10-31T15:26:49+01:00

Trä som konstruktionsmaterial är även specifikt påverkat, då ett nytt klassificeringssytem har införts i samband med övergången till Euorocode. Träts hållfasthet har överlag blivit nedimensionerat och den typ av hållfasthetsvärde som sänkts kraftigast procentuellt sett är hållfastheten tyckt vinkelrätt fiberriktningen. Det uppenbara problemet med detta är att många träkonstruktionslösningar som tidigare klarat de svenska reglerna inte längre räknas hem.<br /> Då det gäller beräkning av tryckhållfastheten vinkelrätt fibrerna för limträ, får numer en faktor av 1.75 användas om längden av upplaget är minst 400 mm. Om upplagslängden är kortare sätts istället samma faktor till 1.0 . Riktigheten i detta kan enkelt ifrågasättas och en mer nyanserad metod för att tillgodoräkna bärförmågans höjning med upplagslängden vore önskvärd. Vidare finns i dagsläget inget direct sätt att inkludera förstärkningar av trä vid hållfasthetsberäkningar av trä tryckt vinkelrätt fiberriktningen. På grund av detta finns intresse<br /> av att undersöka om sådana tillägg i normen skulle vara försvarbara. För att ta reda på om, och i så fall vilka tillägg som skulle behöva göras, avser vi utföra och analysera resultaten av ett antal laborativa tester:<br /> · Limträbalkar av olika dimensioner trycktestas på ett antal upplag kortare än 400 mm.<br /> · Trycktester av limträbalkar vilka förhindras att deformera i sidled.<br /> · Trycktester av limträbalkar vilka är förstärkta med antingen inlimmade trästavar eller inlimmade stålstavar.<br /> Syftet med detta examensarbete och denna rapport är med andra ord att ta reda på om Eurocode tillräckligt bra reflekterar verkligheten eller om vi istället kan ta fram en metod vilken mer noggrant beskriver hållfastheten hos trä vid tryck vinkelrätt fiberriktingen och under olika förhållanden och utföranden. De upplagslängder som undersökts när det gäller oförstärkta limträbalkar är begränsade till 60, 90 och 120 millimeter. Alla spikningsplåtar som använts tillsammans med skruvar för att<br /> förhindra sidledsdeformation hos balkar är 80 millimeter breda, 2.5 millimeter tjocka och 240 millimeter höga. För 60 millimeter långa upplag användes ett lägre antal skruvar i plåtarna för att undvika plasering av skruvar för nära balkkanterna och därmed riskera klyvning av trät.<br /> Trästavarna som använts vid förstärkning av vissa balkändar är 400 millimeter höga med en diameter av 19 millimeter. Stålstavarnas diameter är istället 12 millimeter, dels för att större stavar skulle riskera att klyva trät vid tillverkning, och dels för att vår bedömning är att en 12<br /> millimeters stålstav i det här fallet håller för ungefär samma påfrestning som en 19 millimeters trästav.<br /> Enligt testresultaten presenterade i denna rapport har upplagslängden betydelse för tryckhållfastheten vinkelrätt fibrerna hos trä. Kortare upplag medför generellt högre tryckhållfasthet.<br /> <br /> · Vid 2 till 3 millimeters deformation uppvisar oförstärkta balkar på<br /> 60 mm långa upplag en ökning med 142–133 % jämfört med klossar av samma trätyp.<br /> 90 mm långa upplag en ökning med 93 – 85 % jämfört med klossar av samma trätyp.<br /> 60 mm långa upplag en ökning med 87 – 76 % jämfört med klossar av samma trätyp.<br /> <br /> · Vid 2 till 3 millimeters deformation uppvisar stålstavförstärkta balkar på<br /> 60 mm långa upplag en ökning med 63–158 % jämfört med oförstärkta balkar.<br /> 90 mm långa upplag en ökning med 125–228 % jämfört med oförstärkta balkar.<br /> 120 mm långa upplag en ökning med 64–173 % jämfört med oförstärkta balkar.<br /> <br /> · Vid 2 till 3 millimeters deformation uppvisar trästavförstärkta balkar på<br /> 60 mm långa upplag en ökning med 74– 99 % jämfört med oförstärkta balkar.<br /> 90 mm långa upplag en ökning med 153–203 % jämfört med oförstärkta balkar.<br /> 120 mm långa upplag en ökning med 120–207 % jämfört med oförstärkta balkar.<br /> <br /> · Vid 2 till 3 millimeters deformation uppvisar plåt och skruvförstärkta balkar på<br /> 60 mm långa upplag en ökning med 72–84 % jämfört med oförstärkta balkar.<br /> 90 mm långa upplag en ökning med 95–97 % jämfört med oförstärkta balkar.<br /> 120 mm långa upplag en ökning med 48–57 % jämfört med oförstärkta balkar.<br /> <br /> Baserat på dessa resultat presenteras i denna rapoort en ny modell för beräkning av tryckhållfastheten hos trä. Metoden syftar till att förenkla arbetet med dimensionering av förstärkta träbalkar och innebär en direkt förbättring när det gäller att tillgodoräkna lastspridningseffekter vid tryck vinkelrätt fiberriktningen. Metoden tar dock inte hänsyn till initiella skillnader i styvhet hos materialet, något som i denna rapport observerats i samband med variering av träkroppens bredd. I denna rapport<br /> uppvisar bredare provkroppar generellt lägre styvhet jämfört med mindre breda provkroppar, något som i sig kan ha sin förklaring i andra faktorer än just provkroppsbredd. En sådan faktor kan vara upplagsmaterialet, ty alla oförstärkta, mindre breda balkar vilade på träupplag, medan alla oförstärkta mer breda balkar vilade på upplag av stål. https://lup.lub.lu.se/student-papers/record/3159865/file/3159867.pdf application/pdf 5595993 no 2011 eng Technology and Engineering 0349-4969 TVBK-5209 3159865 2012-10-31T14:57:38+01:00 2012-10-31T15:25:46+01:00 2012-10-31T15:25:46+01:00

Resultaten är snarlika och skillnaderna <br /> dem emellan, med avseende på resultatet, betingas snarare av indatas beskaffenhet än av val av <br /> metod. <br /> Att kunna tillämpa handberäkningsmetoder kan tyckas vara överspelat, med dagens moderna <br /> integrerade datorberäknings- och projekteringsverktyg men det finns exempel på situationer då de <br /> integrerade beräkningsmetoderna inte kan tillämpas. <br /> Tryckfallsberäkning av kanalsystem är långt ifrån en exakt vetenskap, men för att kunna leverera <br /> bra lösningar behöver vi också ha kunskap om de olika beräkningsmetoder som finns tillgängliga, <br /> hur de tillämpas och vilka begränsningar de har. https://lup.lub.lu.se/student-papers/record/3161456/file/3161457.pdf application/pdf 3304103 no 2012 swe Technology and Engineering 3161456 2012-11-01T08:23:17+01:00 2015-07-01T15:00:30+02:00 2012-11-01T09:56:36+01:00

Detta gör byggnadsbeståndet inom EU till den enskilt <br /> största källan till koldioxidutsläpp. Dagens krav om energieffektivitet på moderna byggnader såsom <br /> bostadshus, kontorshus och andra lokaler är ett steg i ledet om att minska energianvändningen inom <br /> samtliga av samhällets sektorer. Dessa krav om minskad energianvändning har lett till ökade <br /> isoleringstjocklekar och hus vars klimatskal är mycket tätare än tidigare. Detta leder i sin tur till att <br /> husen kan komma att bli väldigt varma på sommaren då värmeenergin blir kvar i byggnaden i större <br /> utsträckning. <br /> Examensarbetet syftar till att endast med hjälp av så kallade passiva metoder, alltså utan <br /> energitillförsel, försöka förhindra att byggnader och framför allt bostäder blir allt för varma på <br /> sommaren. För att kunna ge förslag på rimliga åtgärder för att komma till rätta med problemet har <br /> tre stycken betydande värmelaster identifierats. Dessa tre är solinstrålningen under dagen, den <br /> elektriska utrustningen i bostaden samt de boende själva. Av dessa är det solinstrålningen under <br /> dagen som är den absolut största värmekällan och också den enda egentligt intressanta då det inte <br /> går att göra så mycket åt de boende och då den elektriska utrustningen antas vara av relativt <br /> modernt snitt och därmed också energieffektiv. <br /> Studien utförs framför allt för implementering hos befintliga byggnader men resultaten kan även <br /> användas vid projektering av nya byggnader. Tre stycken koncept för att sänka <br /> inomhustemperaturen har prövats. Det första handlar om att pröva fönsterstorlekens betydelse för <br /> inomhustemperaturen. Det andra går ut på att med hjälp av olika typer av solskydd hindra en stor del <br /> av solinstrålningen. Det tredje handlar om att med hjälp av olika sorters byggnadsmaterial öka <br /> byggnadens förmåga att lagra värme och därmed sänka temperaturtopparna inomhus. <br /> De tre olika koncepten prövas med hjälp av datorsimuleringsprogrammet TeknoSim som används för <br /> att simulera det termiska klimatet i ett rum. Rummet som simuleras är ett sovrum i en <br /> bostadsfastighet i området Flagghusen i Västra Hamnen i Malmö. Området uppfördes mellan 2006 <br /> och 2008. Rummet modelleras med dess enligt ritning korrekta geometriska form och ingående <br /> byggnadsmaterial men med en uppskattad mängd möbler, elektrisk apparatur och antal boende. <br /> Resultaten från simuleringarna jämförs sedan med målvärden från branschorganisationen Energi- &amp; <br /> Miljötekniska Föreningen samt med Socialstyrelsens riktvärden för bedömning av olägenhet för <br /> människors hälsa. Även den operativa temperaturen och PPD-index (Predicted Percentage <br /> Dissatisfied) redovisas. <br /> Resultaten visar på att den mest effektiva av de tre åtgärdena är att använda någon form av <br /> solskydd. Dessa fungerar i sin tur effektivast om de monteras utanpå husets fasad och allra bäst <br /> resultat erhålls då detta utanpåliggande solskydd kontrolleras med hjälp av automatik. Är solskydden <br /> istället manuellt kontrollerade av de boende är de långt mycket mindre effektiva. Att ändra <br /> fönsterarean är likt solskydden en åtgärd som ger stort utslag i resultaten men denna åtgärd är också <br /> mycket mer arbets- och kostnadskrävande. Dessutom förändras byggnadens arkitektoniska uttryck <br /> avsevärt vid användning av utanpåliggande solskydd samt förändrad fönsterarea. Resultaten från de <br /> simuleringar då olika typer av byggnadsmaterial prövades visar på att de har en effekt men att den <br /> effekten var alltför liten för att kunna rekommenderas som en realistisk lösning. Bättre resultat Passiva åtgärder för att reducera sommartemperaturer i bostäder <br /> <br /> <br /> erhölls då rummets alla väggar och dess golv var helt i betong, då uppvisades en temperatursänkning <br /> med cirka 3-5 °C. Detta innebär dock att huset måste byggas på detta sätt redan från början. Här ska <br /> dock beaktas att då materialet i väggarna ersattes av betong blev också väggarna tjockare än de <br /> ursprungliga. Anledningen till detta beror på begränsningar hos TeknoSim varför resultaten inte är <br /> direkt jämförbara. <br /> Försök till simuleringar har också gjorts med olika typer av experimentella betongblandningar vars <br /> förmåga att lagra värme är betydligt större än konventionell betong. Tanken med detta var att <br /> relativt tunna skivor av dessa material skulle kunna ha fungerat som en lösning i en redan befintlig <br /> byggnad. Tyvärr gick det inte att, med de beräkningsverktyg som stod till buds, få några resultat från <br /> dessa simuleringar. Det får inte desto mindre anses vara ett intressant alternativ för framtida studier. <br /> En slutsats är att det är av stor vikt att förhindra den direkta solinstrålningen, alltså med någon form <br /> av solskydd. Det får också anses vara det enklaste lösningsalternativet. En annan viktig slutsats är att <br /> det redan i projekteringsstadiet är av stor vikt att inte bara tänka på att dimensionera byggnaden för <br /> vinterförhållanden utan också för sommarförhållanden. Åtgärder i efterhand tenderar att bli dyra, av <br /> olägenhet för de boende samt ganska komplicerade att på ett bra sätt integrera i en befintlig <br /> byggnad. https://lup.lub.lu.se/student-papers/record/3161473/file/3161475.pdf application/pdf 3930333 no 2011 swe Technology and Engineering 3161473 2012-11-01T08:56:47+01:00 2015-07-01T14:56:02+02:00 2012-11-01T09:54:58+01:00

The fire gases can easily spread through the ventilation system if it is not properly designed and some safety measures are taken. <br /> <br /> The current legislation suggest as solution to install independent ventilation systems or smoke barriers. However, the new Swedish legislation will offer new possibilities base on smoke dilution. While the smoke dilution is within a range of values the systems are safe and new design possibilities appear. <br /> <br /> From this point of view, the ventilation system of the project Xchange from the company Skanska has been studied along this thesis. Both the risks from the possible smoke spread through the ventilation system and the opportunities it provides to extract the smoke are considered. <br /> <br /> With the help of PFS, Program Flow System, different ventilation systems are tested in order to find a safe configuration that fulfills all the requirements set by the new legislation. The layouts are simulated under different fire conditions characteristics such as temperature, flow and position inside the building. <br /> <br /> Before performing the simulations, the Xchange project is described and the present <br /> legislation and the fire smoke spread basics are studied. Also the implementation of the <br /> model in PFS is explained. <br /> <br /> The results obtained from the simulations allow discussing the strong and weak points <br /> of each layout in order to decide what layout should be built. https://lup.lub.lu.se/student-papers/record/3161502/file/3161505.pdf application/pdf 2828382 no 2011 eng Technology and Engineering 3161502 2012-11-01T09:18:25+01:00 2015-07-01T15:04:30+02:00 2012-11-01T09:53:43+01:00
