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.

Studies of modern communication media such as Cell Phones and so called Instant Messengers are popular today. This study focused on these modern techniques, focused on parents as a target group and on what is important for them in everyday communication.By exploratory using three focus groups it became clear that the children, and the link to them was the absolute most important thing for the parents. It became clear that this link to a great extent today exists through the mobile phone.In a following study a Mobile Instant Messenger called My Friends was introduced. It was used by two families during two weeks to see how it would change the communication within the family. The focus was to see how problems with availability were handled, it turned out that:My friends had a more obvious way of indicating availability than the Cell Phone had.

AbstractTitle: See each other on the Internet or on a café? A survey about social consequences of Internet usage. (Umgås på Internet eller på ett café? ? en studie om Internetanvändningens sociala konsekvenser.)Number of pages: 34 (including enclosures).Author: Carolin Johansson.Tutor: Else Nygren.Course: Media and Communication Studies C.Period: Fall 2007.University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: The purpose is to get increased knowledge about the social consequences that may come up when young people at the age of 16-20 are using the Internet.Material/Method: The material consists of a questionnaire that I made with questions about Internet usage that 84 young people from five classes (from three different upper secondary schools) answered.Main results: To have access to a computer and Internet and the fact that broadband is more inexpensive now than before leads to an increased usage of the Internet. I found out that chatting, music/movies, searching for information and using the Internet for entertainment is what most of the participants spent the most time on while using the Internet.

The purpose of this ideology critical study is to investigate the hidden content in the reform Gy11 and compare it with the concept new public management. After the clarification of the hidden content, we compare the structure of the organization in Swedish high schools with the structure in public sector called new public management. The main questions of this study are the following: Is it possible to see the foundation of new public management in the Swedish high schools when it comes to the views of knowledge and the formation of goals? Which similarities can we find when we look at the organization new public management and the Swedish high school?The result showed many similarities, both regarding the views of knowledge and the formations of goals. The structure of new public management has been largely implemented in the Swedish high schools and the schools now focus more on instrumental knowledge rather than universal knowledge based on understanding.This is not surprising due to the social progress.

AbstractTitle: A changing climate? A study on the changes of the communicativeclimate. Klimat i förändring? En studie om det kommunikativaklimatets förändring.Author: Anne BjörckAim: The aim of this essay is to study changes in the area of the communicative climate and link that to Karl Weicks thoughts on communication and change. Karl Weick is famous for his contribution to organizational theories and he is still very well used around the world and that is the main reason to why his theory is served as a base in this essay.Method: The essay has a theoretical base with elements of qualitative explorative research method.

The aim of this qualitative study was to study high school PE teachers´ experience of health in high school and how they work with health in their physical education.

The methods for using health in their physical education were divided into three different categories; physical health, improve the individual and theoretical health.

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.

The purpose of this thesis is to find out how clients at Effect Reklambyrå (an advertising agency) view the communication and relationship with Effect. Conclusions are then drawn based on what the clients say. The conclusions show how Effect can improve in these areas.The study uses a qualitative research method since the phenomenon studied is complex and requires deep understanding. A total of 16 interviews took place. Seven clients were interviewed by phone and nine clients participated in a personal interview face-to-face.

The aim of this study was to evaluate parents and course leaders'perceptions of ComHome, a course in communication for parents. Thecourse aims to change the interaction between the parent and the child in aselected play activity based on a defined goal and agreed methodology. Thedata consisted of four group interviews and an individual interview with atotal of 12 parents and course leaders. The interviews were transcribed andcontent analyzed. The study showed that parents and course leadersconsidered goal attainment scaling as a rewarding approach.

The purpose of this dissertation is to create an understanding of how a personal idea in the mind of an entrepreneur becomes an outspoken vision in one biotech company. More specifically, for what purpose the vision is used at different stages, how it is communicated, its content and what impact previous visions have on future vision work and in order to reach a deeper understanding of how vision develops over time and how it is used we have employed a qualitative approach based on a case study. The theoretical framework starts with the concept of vision and related concepts. Furthermore, the entrepreneur?s and manager?s usage of vision is examined.
