Implementation av FlexRay prototypstack
FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.
"En Svensson orkar inte en hel arbetsdag" : En kvalitativ studie om hur hälsofrämjande arbete beskrivs i media
The aim of this study was to understand how social workers deal with honour-related violence, with special focus on the processing from sheltered housing. Our qualitative interviews with social workers that work with this kind of problems show that there are both obstacles and opportunities in the processing from sheltered housing. On the negative side are the loneliness, the shame and the guilt that the girls may experience when they need to leave their families. The social services can both be an obstacles and an opportunity. When the girls need to create a new life in a new city they have a lot of opportunities and in the same time it is hard to get to know new friends when you don´t know the city or have much money.
Representativa testnät försvenska eldistributionsnät
This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Liv med motgångar : en resandpojks berättelse
This is a life story about a man, Victor, and his life. He was born into a family of travellers, this has been a very important part of his upbringing, socializing and how society has viewed him.The purpose of this essay is to discuss how a society's values, and the changes in these values, are manifested in a life story. A person?s identity is created in the situations one is in and in the relationships with ones social contacts. A person has not just one, but several different identities that coexist and are highlighted depending on the situations in which we find ourselves.
Livscykelanalys av avfallsförbränning och biogasproduktion
Livscykelanalys används som metod för att undersöka produkter eller tjänster från ?vaggan tillgraven?. Med hjälp av mjukvaruprogrammet SimaPro utförs en livscykelanalys på förbränning av avfall med energiutvinning. Resultatet jämförs med en livscykelanalys som utförs på biogasproduktion från matavfall, för att visa vilken av processerna som har mer positiv påverkan på miljön. Resultatet visar att förbränning av avfall bidrar till minskad miljöpåverkan med 63,9 kg CO2-ekvivalenter per ton avfall.
Resurseffektiv livsmedelsproduktion : Tillämpning av industriell symbios för ökad resurseffektivitet inom den svenska tomatodlingsbranschen
Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.
Att säkerställa god språkutveckling i förskolan : En undersökning om hur pedagoger arbetar för att främja varje barns språkutveckling
The main purpose of this study was to examine how preschool teachers are working to promote each child's language development and whether they can ensure that they do that. Therefore I wanted to find out what a good language development implies for each teacher, how they work to promote each child's language development in daily practice, how they measure the actual language development and also what conditions the teachers have, to engage in a language development way to work. For the study, I chose a qualitative method, with structured interviews and all together I interviewed six preschool teachers, within the same organization in a suburb close to Stockholm. The results showed that there is an ambiguity, among the preschool teachers, in what a good language development means, but it can be stated that they do have a language development way to work even if it needs to be developed. Further on, it has emerged that the teachers have the tools to measure children's language development, although they do not have the conditions yet to use the method to the fullest. About the preschool teachers own conditions in order to operate in a language development way to work, I concluded that they have a strong foundation to build on, but they still have much work ahead of them.
Datoriseringen i samhället : Äldres upplevelser
As technology have continued to develop over the latest decades and become more advanced the pressure on the general citizens understanding of technology becomes a essential part to live in our society today. The transition have affected our society in great ways and have made a great impact on different groups, one of them being the elderly population in our society. The purpose of this study is to examine how the fast technological development in the latest decades have affected the elderly in our society. This from their perspective by gathering empirical data through semi-structured interviews with elderly people involved in the Agnes-project, a research project focused on improving the general quality of life for older people and increase their knowledge about technology. The study has shown that after the older peoples time involved in the Agnes-project their quality of life had improved in different areas. Areas such as increased cognitive activity, increased interest in new technology and an improvement in their communication with friends and family.
Utvecklingens dimensioner: utifrån ledarskapsutvecklarnas perspektiv
The market for management training programs is growing and the supply of the service is increasing and getting further diversified. A consequence is a market with a wide variety of definitions of the very concept of development, and subsequently a wide variety of practices and methods to achieve development. The individuals that are subject to these programs seldom know what they are purchasing, or what to expect. When assuming a transfer of the developers view on development to the subject, a need for a greater understanding of the concept arises. The purpose of this thesis is to understand what views on development do exist among management trainers and map underlying dimensions of the views to increase the understanding of the concept of development.

This knowledge could be of use to the nurse in her role as a support to the patient in the process of life style change. The result from this study shows that family support, knowledege about the disease and motivation are important factors when changing life style behaviors..
Kvarteret Kajutan - Från lågenergi till plusenergi
Energy and environmental demands regarding buildings have become an increasinglydiscussed topic, both in Sweden and in Europe as a whole. The general trend indicatesthat greater efforts are being put into the energy efficiency of the built environment.There are already numerous examples of houses with a low energy demand, and thenumber of low energy buildings is constantly growing.At the time being, the maximum level for energy demands for housing in Stockholm is110 kWh/m2year, but as soon as next year the limit will be changed to 90. The Swedishagency Energimyndigheten is currently conducting a project to interpret the EU Directiveon the so-called Nearly zero energy buildings, and the preliminary results indicate thatthe level of requirements for purchased energy will end up with about 55 kWh / m2year,which is in line withtoday?s recommendationsfound in FEBY's Kravspecifikation förPassivhus.Starting with a low-energy house in Henriksdalshamnen in Stockholm, we have analyzedvarious energy-efficiency measures and their influence on power and energy needs. Thefinancial aspects associated with the measures have been studied using a model of lifecycle costs.The measures were initially studied individually to give an idea of how much impact theyeach had.

Börja läsa : Den tidiga läs- och skrivutvecklingen
To be able to read and write is necessary to manage well in life. It is important to get a good start in one´s reading and writing development. My purpose in this study was to find out how to teach children to read and write. Obtain knowledge about how to best help children during the early years of reading and writing development, and what is required to teach good reading and writing skills.I wanted to find out how the pedagogues work in the schools, and if they use ant special methods in their teaching. This is something that I, as a future pedagogue didn´t have much knowledge about, which is very important for my future pupils.My research method was qualitative where I interviewed three pedagogues who work whit teaching reading and writing in the early years.
Hjälpkraftsystem med två lågspänningsnivåer
Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..
