Datorsimulering av gruvlastare för funktionell testning
I denna rapport presenteras hur en simulatorlösning för funktionstestning av en gruvmaskin har tagits fram. Arbetet har skett i Atlas Copcos regi och består av tre delar: kartläggning i form av intervjuer, utvärdering av befintliga simulatoralternativ och slutligen val och implementation av lösning. Resultatet visar på en konceptuell prototyp, där en gruvmaskin visualiseras i en 3D-miljö tillsammans med en virtuell gruvgång. Detta möjliggör bland annat testning av autonom navigering, alltså att en gruvmaskin självständigt styr utifrån avläsning av tunnelväggar med hjälp av laser. Samtidigt tillåter lösningen också att kontrollvärden från olika sensorer, såsom vinkelgivare, kan hämtas ut ur simuleringen..

En del av spelet : En studie av fotbollsdomarnas tillvaro i Gästrikland
There is a clear difference between the way football players and leaders regard the role of the referee, compared to the way the refereeing body looks at it. The refereeing body regard themselves as fundamental for the existence of the sport, while the other mentioned parties merely see them as functional justice makers. This view places the referees outside the field of football. This establishes a football culture, which is conflicted when it comes to the role of the referees on the field. The conflict comes to its edge in youth football, where the referees are under severe pressure.

Aktiv lastbilsstol för bättre förarergonomi och hälsa
The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.

Portning och utökning av processor för ASIC och FPGA
In this master thesis, the possibilities of customizing a low-cost microprocessor with the purpose of replacing an existing microprocessor solution are investigated. A brief survey of suitable processors is carried out wherein a replacement is chosen. The replacement processor is then analyzed and extended with accelerators in order to match set requirements.The result is a port of the processor Lattice Mico32 for the FPGA curcuit Xilinx Virtex-5 which replaces an earlier solution using Xilinx MicroBlaze. To reach the set requirements, accelerators for floating point arithmetics and FIR filtering have been developed. The toolchain for the processor has been modified to support the addition of accelerated floating point arithmetics.A final evaluation of the presented solution shows that it fulfills the set requirements and constitutes a functional replacement for the previous solution..
The movement of the rider?s hand related to the horse?s behaviour and the stride cycle
One way of signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse?s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse?s performance and welfare (Manfredi et al., 2010). At the trot there are large vertical deviations of the horse?s body which the rider must adjust and adapt to (Terada et al., 2006) and an unsteady hand due to inability to follow the horse?s movement can be a source of discomfort and conflict behaviour in the horse (Heleski et al., 2009).

Kemin bakom framtidens avgasrening : En studie av ureasönderfall under kvävgasatmosfär
The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.
Att leva med bröstcancer. En litteraturstudie om kvinnors syn på bröstcancer och uppfattning om det sociala stödet
This study describes how the women lived with breast cancer. The purpose with this study was to describe the womens' view on the disease and the understanding they hade on the social support they were depended on. The method was a study of literature with article reviews according to Polit et al., 2001. As theoretical frame of reference we choose Carnevalis model, Everyday life -Functional state of health. The result showed that the following four groups were formed: Support, positive and negative support off nursing staff and significant others.
Evidensbaserad praktik i socialt arbete
The purpose with this review is to investigate evidence-based practice (EBP), and which arguments are used to justify EBP. The year of 2006 Bergmark and Lundström published an article regarding the problems concerning EBP. They are discussing that several different definitions of EBP are existing, which they mean can lead to difficulties using the EBP-methods in real life. In this study six articles, from the years 2007-2011, have been analyzed using Mertons structure-functional theory and Lipskys theory of street-level bureaucracy. Different definitions of EBP are discussed in the articles and there seem to be a need to clarify the concept.
Matematik och flerspråkighet : När invandrarelever lyckas
The aim of this paper is to investigate and analyze practices in multilingual classrooms of mathematics in a compulsory school in Sweden where immigrant students have been known to succeed. The school is situated in a suburban and segregated area outside a major city where pupils come from mainly limited socio-economic backgrounds. The rate of second language learners are 70% of all pupils in this school.By using ethnographic methods, mainly interviews and participant observation, data was collected in four mathematics classrooms which corresponded to consecutive ages of education. The data include field notes and observation of artifacts in the environment as well as interviews and informal conversations with teachers and school leadership. Information from the school website, the authority in charge of quality in Swedish schools (Skolverket) and the municipality were also used.The analysis is based on a socio-political viewpoint that power is relational and reflected within schools.
Första avstampet för att konstruera en digital stadskarta för personer med nedsatt syn
The physical map that has been used until now can in the modern days be replaced with digital maps available in smart phones and tablets. One disadvantage of both is that the digital maps require the user to have a fully functional sight. The problem with the research done so far is that it provides little explanation as to why developers have decided to design the maps in a specific way. This thesis has been designed to address this problem.In order to provide the knowledge needed, a literature study was done to construct interview questions to an employee from SG Access AB. These answers and the literature study were used to construct interview questions to members and employees from Synskadades Riksförbund (SRF).
