Vad har en simulerad modell av ett fordon och en sportbil med 500 hästkrafter som körs på en frusen sjö i norra Sverige gemensamt? Jo, båda används eller kan användas till att testa den mjukvara som styr BorgWarners fyrhjulsdriftkopplingar. Genom att använda en simulerad bil och specialutvecklade testfall kan mjukvaran testas i alla tänkbara miljöer utan att behöva skeppa runt en riktig bil, även This Master’s thesis investigates if a previously integrated Simulink based vehicle model works for testing and verifying software on an ECU (electronic control unit) used to control a four-wheel drive coupling in cars. The testing is done through a specific program called CANoe that allows the tester to both develop and run test cases. This work also investigates the possibility to use static eva

This study aimed to identify which management and leadership soft skills project managers in project-driven industries are required to have, to contend with complexity and change. To gain a holistic understanding, this knowledge was generated through four different research methods: literature research, interviews with twelve experts across the automotive and IT industries, interviews with five cl

Kalkning ger nytt liv till sura sjöar Försurning är idag inte något som det pratas speciellt mycket om i fikarummen runt om i landet, trots att det är ett problem som fortfarande lever kvar och som man jobbar för att lösa helt och hållet. Kalkning kan hjälpa till att återskapa livsmiljöer för en mängd arter i försurningsdrabbade vatten, men hur har egentligen utvecklingen i sjöarna sett ut sedan Acidification was one of the biggest environmental issues during the 20th centaury, especially in Sweden since acidic emissions from other regions ended up in the ground and water here. In this study, data from several lakes in Ulricehamn Municipality was analysed with consideration of acidification. Liming has been carried out in three lakes, Surströmmasjön, Vallsjön and Trehörningen, since the 1

Cancer är en av våra vanligaste sjukdomar och det pågår mycket forskning kring att hitta nya behandlingar. För att en ny behandling ska kunna erbjudas till cancerpatienter behöver behandlingens effekt och säkerhet utvärderas och säkerställas i en patientstudie. Effekten bedöms vanligtvis genom att mäta tiden det tar för cancersjukdomen att sprida sig och/eller tills patienten avlider. Generellt fåTime to disease progression or death (PFS) is of main interest in oncology clinical trials. The data is commonly analyzed using a Cox model. Early discontinuation gives uncertainty in the estimated hazard ratio (HR). Censoring is generally used to handle discontinuations. However, if discontinuations are related to the patients’ prognosis, the HR may be biased. By simulating PFS data, this bias wa

In this project we present a phenomenological study of signal to background interference effects in leptonic tridents produced in parton showers. The interference effects are introduced by linking matrix element corrections of a kinetically mixed dark photon model to the parton shower Dire. Using different dark photon masses and coupling strengths positron+proton collisions are simulated and diffe

Mänsklig aktivitet leder till ett konstant och oundvikligt flöde av olika typer av avfall som måste hanteras och behandlas. Hushållsavfall, sådant avfall som uppstår i våra hem samt i bland annat skolor, vårdinrättningar och arbetsplatser, är den mest komplexa avfallsströmmen att hantera. Detta eftersom den vanligtvis består av mängder av olika material såsom papper, plast, glas och matrester. VärManagement of municipal solid waste (MSW) is an urgent issue throughout the world. Urbanization, population increase, and economy growth are all factors which contribute to an increase of MSW generation. The most common treatment method of MSW is through landfilling, which lead to a constant dissipation of resources in terms of material and energy, as well as environmental pollution and emission o

Thin-Film Transistor (TFT) technology refers to process and manufacture transistors, circuits, Integrated circuits (ICs) using thin-film organic or metal-oxide semiconductors on different substrates, such as flexible plastic foils and rigid glass substrates. TFT technology is attractive and used for applications requiring flexible, ultrathin ICs to enable seamless integration into devices. TFT t

Gated Recurrent Unit (GRU) neural networks have gained popularity for applications such as keyword spotting, speech recognition and other artificial intelligence applications. Typically for most applications training and inference is performed on cloud servers, and the result are transferred to the power constrained device, e.g., an hearing instrument (HI). This approach has disadvantages such as

The purpose of this study is to gain a deeper understanding of what leads an employee to judge an event as fair or unfair through the lens of sense-making, sense-breaking and sense-giving, within mergers or acquisitions. This study had an abductive qualitative case-study approach, mainly focusing on semi-structured interviews. Our study constitutes based on the theory of perceived fairness in orga

Kommunikation är en sådan central del av vår vardag att vi ofta glömmer hur komplicerat både att tala, men även att lyssna egentligen är. Forskning kring dessa ämnen har gjorts länge, men ännu finns det saker vi fortfarande inte förstår till fullo. En sådan sådan sak är det så kallade Cocktailpartyproblemet, vilket avser hur människor så enkelt kan urskilja röster även i fall där mycketbakgrundsljThe cocktail-party problem relates to the challenge of separating a single sound source from a noisy and crowded background based on the listener’s attention. Earlier work has been done in order to use the relations between the sounds heard and the following brain response to develop a model that can accurately classify which sound an individual listener is listening to. The model deals with an re

The primary focus of this study is to determine the effect of additional education on the wage earnings structure in Uganda. The study is empirical and uses data obtained through the Uganda National Housing Survey (UNHS) 2015/16 in the World Bank Database. The study employs the Mincerian wage function as the main model with different specifications that cater for urban-rural, regional and gender d

In recent years, there has been a surge in research on menstrual poverty in Sub-Saharan Africa, and scholars are debating which interventions are the most appropriate. One of the leading theories is Civil Society Based Intervention which prescribes a mix of sanitary product-provision and menstrual education. This study contributes to the discussion by testing the Civil Society Based Intervention o

Byggnationen av bostadshus med trästomme har enligt Statistiska centralbyrån ökat med 85% efter den senast lägsta uppmätningen 2011. Statistiska centralbyrån menar också att det är bostadshus bestående av 4-8 våningar som byggs mest i Sverige idag. Av denna statistik förutspås det bli en ökning av efterfrågan på bostadshus med 4-8 våningar med trästomme inom den närmsta framtiden. Tillsammans meThe construction of residential buildings with timber as load-bearing system has according to Statistics Sweden increased with 85% since 2011, which is the latest low point of the collected data. Statistics Sweden also shows how residential buildings consisting of 4-8 storeys are, in Sweden, the most built type of house today. Of these statistics, 4-8- storey residential buildings made with timber

Mörk materia är en av huvudkomponenterna av universum. Det går inte att observera den på något direkt sätt, men dess närvaro är uppenbar, eftersom rörelsen av stjärnor och gas påverkas av dess dragningskraft. Mörk materia bildar gravitationsbundna klumpar som kallas för halos. Att förstå dessa objekt utgör en grundläggande del av kosmologin, vilket är vetenskapen som handlar om universums usprung It was previously found that the density profile of dark matter halos is well-fit by a universal, smooth function over a vast range of masses and redshifts, named the Navarro-Frenk-White (NFW) profile after its discoverers. Despite its impressive goodness of fit, the NFW model remains an approximation of the density profile of realistic halos. In the literature, this model has been used for fittin
