This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.

This reportcommunicates the processes and results of my degree work in industrial design at candidate level at Umeå Institute of Design.During my degree work I had a cooperation with Svenska Jägareförbundet (Swedish Hunters Assosiation).The aim for my project has been to explore how I could make hunting a safer hobby and undertaking. Every year people get seriously injured and in average 2 people a year dies  due to hunting accidents. My goal is to identify problems within the hunters communication and approach. Through a creative design process I will find a valid  nd realistic solution to these problems. My project will be presented as a conceptual solution  hat will be based on currently existing technology.

Problem: What are the characteristics of Polykemi?s management control system and how is it affected by growth? Purpose: To describe and analyse the management control system of a medium-sized family-owned company from the perspective of Simons? Levers of control. Research design: An abductive, interview-based case study of Polykemi AB. Conclusion: Polykemi?s management control system is primarily a traditional one which is rather strong in terms of Levers of control.

I en delstudie till IDA-projektet har 185 kvinnor i 40-årsåldern skattat sin stress med PSS (Perceived Stress Scale) och genomfört fyra episodiska minnestest. Ett omvänt U-format samband med PSS som oberoende faktor och prestation i de olika minnestesterna som beroende faktor har prövats. Ett linjärt samband har sökts post hoc. Både explicit och implicit minnesprestation har mätts, liksom primär- och sekundärminnesprestation. Hög- och lågutbildade deltagare analyserades separat.

Socialt stöd bidrar till mindre risk för yrkesrelaterad utbrändhet. Var tredje lärare uppvisar inom sina första arbetsår symptom på utbrändhet. Syftet med föreliggande studie var att undersöka samband mellan socialt stöd och utbrändhet hos grundskolelärare. Totalt deltog 71 respondenter i Stockholm via enkäter. Socialt stöd mättes via Berlin Social Support Scale och utbrändhet mättes med Shirom Melamed Burnout Measure.

My goal with this Project was to create four pictures which de¬scribed four different emotions. The purpose of the project was that the pictures would be placed in a psychology department and they could use them as a starting point for a discussion about the patients? emotions. My personal purpose was that I wanted to create pictures in scale 1:1 in an analogue fashion, and try to learn more about how people see and feel about pictures. What kind of thoughts can a picture give you? Can I create a picture which can be used as a platform for a discussion? Can I make a picture which describes an emotion? The making of the pictures started with developing ideas and then I took photographs of my friend Joel, in different situations and moods, which I used as reference for my paintings.

At the plant of Sandvik do Brasil in São Paulo there is a need for improving the transport of inserts between the plant building and the stock building. The idea is to install a system with an Automated Guided Vehicle (AGV) to take care of this transportation. The purpose of this report is to present which demands there are on the system and to find the best solution according to the demands.To conclude this work a study was made of the plant and the AGV technology was examined. Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..

This thesis was conducted at Linköping University and Saab Aerostructures DPS, Linköping, and focuses on the possibilities of flexible fixturing in machining applications. The thesis is part of the research project "Koofix", which is collaboration between Linköping University and a number of companies.The thesis is aimed towards small batch production which, for Saab Aerostructures DPS, means diverse part geometry and that parts are manufactured in very small numbers, sometimes just one piece. The result of this is that expensive dedicated fixtures are made for most parts. By introducing more flexible fixturing methods to this kind of production the cost of fixtures and tooling will be reduced, and make the production more efficient.New flexible fixturing methods has been presented and evaluated through the thesis, which has resulted in three different concepts. These concepts have been the result of literature screening and study of current manufacturing process at Saab Aerostructures DPS.

Depressionssjukdomar är vanligt förekommande och medför stor sjukdomsbörda. De psykologiska behandlingsmetoder som visat sig effektiva vid depression är bland annat kognitiv beteendeterapi (KBT) och beteendeaktivering. I denna studie undersöks effekterna av internetbaserad KBT med behandlarstöd vid mild till måttlig egentlig depression. Totalt 80 deltagare randomiserades till behandling respektive kontrollgrupp. De mätinstrument som användes i studien var självskattningsformulären Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Montgomery Åsberg Depression Rating Scale Self?assessment (MADRS?S) och Quality of Life Inventory (QOLI).

To this day, battery of women is a global problem. The aim of this paper is to examine this problem in the country that is considered to be one of the most equal countries in the world, namely Sweden. How big a problem is it, what is the social outlook of the victim and how does the Swedish justice system respond to this issue? These are some of the questions that will help to form an answer to the question if Sweden is a sanctuary for femalebatterers.Due to the resistance of implementing the entire penalty scale and the use of judicial methods, such as restraining orders and its effect on the women, the conclusion drawn from the answers is yes - Sweden is that sanctuary. The Swedish justice system is not tough enough when it comes to the abuse of women.
