The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

The purpose of this essay is to examine the Swedish people?s level of knowledge about crowdfunding and their incentives and deterrents to crowdfunding investments. Early on crowdfunding was divided into two objectives: reward based and equity based crowdfunding. The division of objectives is logical due to the differencing conditions of the motivation for investors to invest. Supported by theories in crowdfunding incentives, commitment-trust, the prospect theory, and the diffusion of innovations, we aim to establish a comprehensive line of reasoning to support our model of motivation in the conclusive chapter.The results of this essay were achieved by a combined method.

The purpose of this study is to examine how school meals are organized in a selection of Stockholm's secondary schools and to examine the relationship between school meals and the different parameters that indicate each school's symbolic capital and educational capital. By looking at the statistics from each school on the basis of the final grade average, percentage of pupils with foreign background and gender, I examine whether it is possible to see a relationship between how schools organize meals and which pupils attend the school.  In my study, I systematically went through each school's website and tried to identify how school meals at each school are organized. To increase the validity of the study, I have also conducted a questionnaire survey by mail addressed to school principals.   In order to analyse and understand my results and put them in relation to my current knowledge about the schools in my sample, I am using Bourdieu's theoretical tools that a given aid, both in methodological and analytical purpose. Based on Bourdieu's theories of symbolic capital, cultural capital and educational capital, I can understand and analyse school meals are organized and focused as part of schools' symbolic assets in competition with other schools.   The first part of the study shows that there are four different organizational models for school meals, fully equipped kitchen and canteen, heating kitchen and canteen, school meals in restaurants and school meal card.    In the second part, I have examined the relationship between the type of organization for school meals used and the symbolic resources available at the school. I can conclude from the results that it is difficult to find a correlation between the symbolic resources and the different categories. But even though it is not possible to see all the schools' symbolic assets equally clear, there are still some very telling examples. In many ways, these examples can be seen as polar opposites to each other based on Mikael Palme?s concepts ?goal rational? and ?education oriented? schools..

The environmental situation is becoming increasingly critical. The energy sector and other industries have a big impact on our climate and the public is raising their voice for companies to admit their responsibility towards the environment and society. Companies engage in corporate social responsibility (CSR) and happily disclose their responsible performance in annual reports. But what messages are they conveying in their CSR-reporting, and what attitudes towards CSR can be found underneath the explicit content? The aim of this study is to discover which discourses exist in CSR-reports from Swedish energy companies, and how these discourses operate.

I takt med att inköp har fått en allt mer betydande roll inom företag krävs det också att strategier för inköp utformas på ett sätt som möjliggör att de kan efterlevas och följas upp, framförallt när det rör sig om koncernövergripande strategier som kräver samordning. I dagsläget är det inköpsrådet på Saab som styr över och samordnar projekt och initiativ som sker inom inköp. Inköpsrådet ansvarar även för framtagandet av inköpsstrategier och arbetet utifrån dessa för hela koncernen. En första klassificering av Saabs leverantörer utefter Kraljics matris genomfördes år 2010 och i samband med detta har ett ökat intresse påvisats för att på ett differentierat sätt mäta och följa upp leverantörer. Syftet med studien är därmed att se vilka Key Performance Indicators (KPI:er) som är tillämpliga i en indelning av leverantörer enligt Kraljics matris, det vill säga om olika KPI:er är fördelaktiga för att genomföra mätning och uppföljning av olika typer av leverantörer enligt Kraljics matris.En betydande slutsats med indelning av KPI:er enligt Kraljics matris är att studien ska påvisa vilka mätetal som är mest väsentliga att ha vid uppföljning av leverantörer kopplade till respektive kvadrant i Kraljics matris.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Abstract: The purpose of the study was to analyze the experience of being a woman diagnosed with ADHD as an adult. Another aim was to analyze how the women think itwould have influenced them, if they had been diagnosed during childhood.In the study, with a qualitatively approach, three women diagnosed with ADHD were interviewed. The data was analyzed with qualitative content analysis.The result shows that the women perceived affirmation when they received their diagnosis but they also pointed out that they had wished to receive the diagnose during childhood to avoid unnecessary suffering.The conclusion of the study was that it is essential to, as early as possible, follow up deviances in children and adolescents. Therefore, there is a need for more knowledge of how symptoms of ADHD in girls present itself.It is reasonable to believe that if healthcare and school have increased knowledge of symptoms of ADHD in girls, then these girls would be diagnosed at an earlier time.Keywords:ADHD,women,girls,treatment,self?esteem.

The information flow is a very important process in an organization. It affects in a decisive manner the effectiveness of a task. It also has a major impact on the quality of the product or service for which the organization delivers to its customers. Lack of information may cause that important aspects are not given the required attention or even forgotten and can in turn lead to criticism from certification officials and lower customer satisfaction. The purpose of this study was to study how the information flow in Norrskog?s field organization is handled and how this affected the quality of the work performed and the feedback given to the contractors, The study is based on qualitative interviews with contractors, production inspectors and forest inspectors on all Norrskogs districts.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

This essay is a study of the use of IT technology by teachers of English and History at a Swedish upper secondary school. It is based on four interviews and four observations. In my analysis of these I have made use of the theory of Social Shaping of technology, a theory which puts emphasis on a teacher´s purpose regarding the use of IT technology in order to empower the teaching process. As a researcher I aim to explore the reasoning on the part of the teacher and to that end I use the method of interviews and observations. This study shows different ways of using IT technology varying from one teacher to another.
