When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

Ethanol fuel is a biofuel, which been widely reported in the public debate and on the fuel market the last years. Ethanol is sold as both E85 and as a five percent admixture of all petrol sold in Sweden. Research studies on ethanol fuel often focus on environmental issues surrounding the production and utilization of ethanol as a fuel, and omits the private and business aspects of the subject. The purpose of this study is to illustrate the economics of ethanol as a fuel. How the Swedish market for ethanol is and how it evolved over time and what the future prospects are.

Syftet med denna studie är att undersöka hur elever samarbetar i skolslöjden och vilka funktioner detta samarbete fyller. Genom att observera hur elever i årskurs nio samarbetade under slöjdlektionerna samlades material till studien in, material som sedan analyserades och kategoriserades.Resultatet av analysen blev fyra kategorier, eller typer av samarbete;Kunskapsförmedlande samarbete, Diskuterande samarbete, Samarbete när den egna kroppen inte räcker till samt Bekräftande samarbete. Analyser gjordes även av hur tillgängliga lärarna var under de olika lektionerna och hur detta kan ha inverkat på elevernas samarbete, samt rummet och arbetsmiljöns förmodade inverkan..

The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

This master?s degree thesis stems from the new possibilities that digitization offers preserving and increased public accessibility of our cultural heritage, but also how a lack of co-ordination and standardization may result in short-term projects and lack of quality. The purpose of this thesis is to examine a selection of public libraries? digitization projects. The two questions posed are:How does a selection of public libraries conduct their digitization projects concerning a) goals and objectives, b) execution c) what resources they encompass?How well does their work agree with the recommendations that exists for goals, objectives and execution?To answer the questions interviews were conducted with persons in various ways involved with the digitization projects.

The purpose with our research in Varbergs Kurort is to study how persons that have been a part of the individual adjusted rehabilitation program First Step have found their stay during their program. The program holds a team of professionals that together work with the individual?s physical and mental health. In our study we have included eight women and to men in the age between 35-65 years who all suffered from a slight mentally illness. Out of a social psychological perspective we have based our study from the social and room environment and how their self-recovery has affected their wellbeing during their rehabilitation.

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.

The purpose of this study is to examine immigrants' experiences of social services' treatmentand their expectations of social services. In this study we have used the following questions:how immigrants have experienced the treatment of the social service, the way in whichimmigrants would like to be treated by social services as well as what kind of beliefs andexpectations immigrants have concerning the social services' duties and powers. We haveused a qualitative method in the study that consists of ten semi-structured interviews. Thetheoretical concepts we have used are culture, ethnicity, cultural competence, professionalismand social psychology. The survey reveals a majority of negative experiences, such as afeeling of being ?tossed around?, suspicion and discrimination by the caseworkers due to theethnicity of the respondents.

Process standardization is a topic that has generated a lot of research and literature. At first, the focus was on production; today processes are used in all different kind of business areas.The aim of this study has been to analyze how processes can be applied on development businesses and how IT systems affect the result of the process. To accomplish this, we have asked questions such as what standardization is in a development process? Why are the processes standardized? What difficulties can appear with standardization? And how the IT-systems affect the result of the process?To answer these questions, we have preformed a case study on Saab. Saab is a well know Swedish company who are working with a project called the GMS-project, where they develop processes to cover the whole company´s business areas.The literature gives the reader an understanding of processes and standardization.

The properties of this material has been studied and it was found that there is very little difference in what affect students in there choice of school, studies and career. Boys who choose hairdressing and styling differ more than girls who choose a career in technics. This is a surprising result which we didn´t expect. In researching background material we learned that it should differ more in perspective of gender. We have compiled the material around young people's choices to high school.

In this thesis, I discuss the impact Swedish national culture may have on Swedish diplomats. This is a qualitative study and I have used theories from studies of international negotiations to compare the oppositional results of those scientists with my interview material. With the help of my interview material from seven Swedish diplomats and five foreign diplomats I have compared their perceptions of Swedish culture, Swedish diplomats and their thoughts about the existence of an international diplomatic culture with well known sceientists of international negotiations. My main question is whether there is an international diplomatic subculture, without any national impact, or not. The mission is to base the thesis with earlier science and then compare and contrast with my interview material.

AbstractEvidence based research has shown that organized parent support programmes have a goodeffect in strengthening the role of the parent and preventing problems during growth. Thisin turn has a great significance for Public Health.Komet is one of the evidence based programmes used in Sweden, based on Americanprogrammes and adapted to Swedish conditions.This qualitative study consists of interviews with six children between six and nine yearswith behaviour problems, whose parents have taken part in the Komet programme.With Grounded Theory as research approach the children?s experiences of the programmeand relations within the family have been looked into and analysed.The result of this study suggests that a space for growth of their own is a common need ofthe children, and that this can be achieved by giving them the opportunity to function in afamily environment where they are seen and understood.The Komet programme contributed to this by giving the family tools to strengthen relationswithin the family, create calm and make the children more visible.The self image of the children in this study had improved which gave them more room togrow in a strengthened family situation. This in turn improved conditions for good feelings,and sense of well being, of importance for child development and health..

Studien syftar till att ta reda på och beskriva vilken medvetenhet som finns hos svenska textilkonstnärer när det kommer till produktionen av de textila naturmaterialen bomull, lin, silke och ull. Mina frågeställningarär hur svenska textilkonstnärer förhåller sig till ursprunget och produktionen i införskaffandet av deras textila material, samt hur de förhåller sig till ekologiskt respektive rättvisemärkt material i relation till sitt skapande.För att ge en bakgrund till detta inleds undersökningen med en kvalitativ litteraturstudie där jag beskriver den konventionella, respektive den ekologiska produktionen av de fyra ovan nämnda naturmaterialen, samt ger en beskrivning av textila märkningar och rättvis handel med textil. Genom en enkätstudie har jag sedan ställt frågor till tretton svenska textilkonstnärer som använder sig av bomull, lin, silke och ull för att ta reda på hur de förhåller sig till produktionen av dessa. Svaren från enkätstudien har sedan analyserats och resulterat i ett antal slutsatser; det finns stora brister i konstnärernas kunskaper kring produktionen av deras material. Flera tycker dock att de borde veta mer, och nio av tretton konstnärer svarade klart och tydligt att de var intresserade av att veta mer.

Finns det föreställningarna av rum och dess befintliga rörelser och struktur? Inom Inredningsarkitekturfinns det ettförhållningssättdär den praktiska funktionen är viktig. Där funktion betyder attvara aktiv i rummet, attkunna beröras av material tex möbler som social struktur för attkanske kunna producera för en konsument/brukare.Går det attlösgöra förväntningar och föreställningar från sin ram eller attvidga dessa i den rumsliga aspekteten attfylla något med känsla i stället för en brukande funktion? Om man reducerar funktionen, vilket betyder för mig, om man tar bort möbler och material och bara förhåller sigtill det mänskliga i ettrum. Vad blir kvar? D.v.s.

The aim of this study is to analyze how intercommunication between offenders are presented with artefacts during the planning and implementation of a robbery in a cash depot in Stockholm. The methodological approach is based on empiricism from police investigation protocols, which leads this study to a case study. The ambition is to analyze the empirical material from a sociocultural perspective. The results shows that the offenders use artefacts to plan the crime with artefacts within an internal intercommunication between the offenders. After the planning artefacts such as a helicopter, explosive material, telephones, saws and ladders have been used in an intercommunication to implement the robbery which leads to an analysis that hierarchy depends on the role of the artefacts, only when technical artefacts are included in the term of hierarchy..
