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.

AbstractDuring the year 2005, a more and newer models of trade as shopping malls has been established in Värmland. Trough media (Wermlands the newspaper, Tvärsnytt) we have been able to follow the development of trade establishments as happened in the county, for example the establishment of Olav Thons Shopping center in Töcksfors. The aim and issues as then arisen in this study is part's why economic activities as shopping center increases precisely in Värmland, part's factors that governs the premise ice ring of a shopping center, were Töcksfors shopping center is functioned as an example, part's if shopping centers is a part of Värmland's new tourist activity? Through depth interviews with the region manager Urban Svanberg on Swedish business communities, the centre manager Helene Rödseth on Töcksfors shopping centre and the county tourist manager Monica Karlsson on Värmland's tourist council, some cultural geographic premise ice teories has been showed. For example this study has shown that trade in Värmland has been given birth to new trades in the county..

The overall goal of this diploma work is to produce a design of a 5 GHz radio frontend using Agilent Advanced Design System (ADS) and then build a working prototype. Using this prototype to determine if RF circuits at 5 GHz can be successfully produced using distributed components on a laminate substrate. The design process for the radio front-end consists of two stages. In the first stage the distributed components are designed and simulated, and in the second stage all components are merged into a PCB. This PCB is then manufactured and assembled.

This is a qualitative study that has investigated four people's experiences of making a physical change of life. With narrative depth interviews, the study was characterized by the informants own experience of their experiences and thoughts. With questions surrounding their experiences of alienation, belonging to the standard, people's attitude and prejudices against their appearance. The investigation revealed that the informants experienced shared experiences and things that separated them. The conclusion based on the people in this study was that people with low self-esteem are at greater risk for experiencing alienation.

We chose to base our literature study on the meme phenomena. The meme is a portion of culture that is spread among us from mind to mind. Every time we learn something by copying others we use information that has been passed on from a previous person, that information can be seen as a meme. The theoretical frame for our methodology in our exam paper is founded on Forsberg och Wengström research on literature studies. Our aim is to describe to the reader in depth what a meme is and how they could be helpful in an academic and pedagogical setting. Our study will show how memes are seen predominantly as graphic designs and as artifacts for cultural representation parallel to their imagery.

In the coming years, organic food waste will be collected in the region of Gästrikland, Sweden. The collection is planned to cover the entire region by the end of year 2007. To start with, smaller amounts are being collected and transported to a central composting plant in Sala. However, a central composting plant in the region of Gästrikland is projected.The objective of this thesis is to evaluate a number of possible methods for composting of organic food wastes regarding their environmental impacts and localization.There are four scenarios for future composting of organic waste that have been evaluated. There are two that consist of membrane composting, either in Sala or in the region of Gästrikland.

With this thesis I have examined the views of religion among six comparative religion teacherstudents, with the perspecitve of their life stories. I have also examined what stance they want to take due to their personal beliefs in their forthcoming teaching. To achive this I have used in-depth interviews among the six soon examined teacher students, and within the interviews I have had a particularly focus on turning points of the students? life stories. Later on I have used their turning points in an analysis with the hypothesis of ?Rites des Passage? and ?Structure and Anti-Structure?.In my survey I have found a significant relationship between the students? life stories - inparticularly their backgrounds and tourning points - and their views of religion.

IT is a natural part of the work today when it comes to projects. There are many aspects that are wholly or partly dependent on IT support actions to proceed efficiently. Although there is still situations where IT is deselected as a tool. The factors that make it look like this is not always included in the calculation, which resulted in the failure that could have been remedied with the right tools to solve the problems. The project form which today is increasingly common with all major groups involved enables IT tools' impact also becomes an increasingly provided they are used properly.

In query expansion (QE) terms are added to an initial query in order to improve retrieval effectiveness. In this thesis we use QE in the sense that a reformulation of the query is done by deleting the terms in the initial query and instead replacing them with terms from the documents retrieved in the initial run. The aim of this thesis is to, in a experimental full text invironment, study and compare the retrieval result of two different query expansion strategies in relation to each other. The following questions are addressed by the study: How do the two strategies perform in relation to each other regarding recall? What may be causing the result? Are the two strategies retrieving the same relevant documents? Two strategies are designed to simulate a searcher using automatic query expansion (AQE) either with or without relevance feedback.

Sammanfattning:De ökande testdatavolymerna som krävs för att testa moderna System-On-Chip (SOC) bidrar i hög grad till den ökande produktionskostnaden. De stora testdatavolymerna kräver stora och dyra Automatic Test Equipment-minnen (ATE-minnen). För att minska behovet av dessa minnen så har olika komprimeringsmetoder utvecklats.Denna rapport beskriver arbetet med att implementera en given komprimeringsmetod för testdata till SOC. Den metod som används heter vector repeat och den implementeras genom skapandet av ett för ändamålet avsett dataprogrogram. För att vector repeat ska fungera effektivt så förutsätts det att in- och utgångarna på den ATE som används kan delas in i olika portar.

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.
