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.

Society is facing rapid and continuous change. In order to participate in the development, organizations need to take advantage of all the knowledge and skills available in the labor market. Women leaders in top positions are still in the minority but do as good a job as their male colleagues. She brings different dynamics and a new dimension in the work culture but is nevertheless excluded from the mightiest rooms. The purpose of this study is to elucidate the organizational factors that determine and facilitate for women to take on leadership positions.

Civil society is facing many challenges in modern society and there is a lot of debate about where it is heading - is volunteer work declining or just taking a new form Whichever hypothesis will prove correct in the future, organizations that are dependent on volunteers will need to adapt to the new circumstances. This study aims to examine what forces drive voluntary work at Rädda Barnen (Save the Children Sweden) and Hungerprojektet (The Hunger Project Sweden). Through interviews with employees and volunteers at the two organizations, this study finds that volunteers at Rädda Barnen are primarily driven by values and understanding, and that the volunteers at Hungerprojektet are primarily driven by career and to some extent by values, enhancement and social factors. Understanding these driving forces allow the organizations to adapt to the new circumstances by matching the volunteers interests with the organizations' needs..

Increasing volatility and less political intervention from the CAP in the market price of wheat is making it more difficult than in the past for Swedish farmers to determine the price at which they should sell their wheat. In the past, the Swedish farmer-owned company Lantmännen has traditionally set a guideline price for Swedish wheat every year to which farmers could adapt, but ceased doing so last year. Therefore this study sought to identify the parameters on which the price of wheat is dependent on by using a reduced form model. The perspective adopted was that of farmers. The model proved able to identify the main factors determining the annual price fluctuations in wheat, with all variables included having an impact on the wheat price, except export quantity in the previous year.

Background: Increasingly, companies choose to finance their business with corporate bonds which has resulted in an increased demand on credit ratings. As such the rating agencies have a very important role in the financial markets. Examining the value of a credit-rating can be very interesting for both issuer and investor. Purpose: The purpose of the study is to identify and define the value of rating. Execution: The study is built upon nine interviews with rated and non-rated firms and investors.

This study is about the female entrepreneur in rural areas in Sweden. Five women were interviewed with the aim to examine their way of living (livsform), their motivation, what significance it is to be a woman in business and how female entrepreneurs can be encouraged to start their own business. The conclusions : ? The women in this study live an independent life , but the their way of life (livsform) has changed during their life ? Female entrepreneurship can be promoted trough greater knowledge of the female business, better advice to the entrepreneurs, more networking groups and reducing bureaucracy. ? The driving forces for the women is to do what they like and are interested in, at the same time as they have time for the family and children. They also like to work in the rural areas. ? Female entrepreneurship can be promoted through greater knowledge of female businesses in the community, by creating virtual meeting places such as networking groups and mentor groups on internet.

Abstract (Engelska)The aim of this study is to investigate who is being emphasized, constructed and normalized as the addressee written for, in the text book ?Körkortsboken 2013?. Körkortsboken is used as the major textbook in the theoretical part of the education necessary to obtain a drivers? license in Sweden. Most people in Sweden obtain a drivers? license, sooner or later.

A rhetorical analysis of the educational interactive film ?Riskprofilen?, produced by the Swedish Civil Contingencies Agency (Swedish: Myndigheten för Samhällsskydd och Beredskap). This essay uses the theories and methods of Procedural Rhetoric, as described by Professor Ian Bogost, and Visual Rhetoric, as described by Professor Brigitte Mral to analyse the interactive and visual component parts of the artefact, and compares them to the intended purposes of the artefact as stated by documents pertaining to its creation, found to be those of educating the public; marketing the agency; and driving traffic to its webpage. The artefact is through analysis found to fulfil the purposes of marketing the Agency and of likely increasing traffic to the website upon which it is hosted. Regarding the primary, educational purpose this analysis finds that the artefact does not teach a user the accident-avoidance strategies it claims to do, but is dependent upon further materials..

This study´s focus was a group of participants of a social movement called The Zeitgeist Movement. The purpose of this study was to understand and convey what causes participants of this movement to engage despite that the prevailing culture teaches them otherwise.With qualitative methodology of participatory observation and semi-structured interviews with ten participants, our objective has been to answer the following questions: What are the driving forces that make these people act, which approach do they have to ?reality? and how do they relate to it, and what are the potential consequences with this approach?The study has shown that their critical and questioning attitude towards their perception of reality and their social constructivist view of it lead to conflicts between them and their fellowmen. The data was then analyzed with Alfred Schütz phenomenological theories in synthesis with Zygmunt Baumans critical societal analysis and theories.The study's focus was on the Gothenburg chapter of the Swedish Zeitgeist Movement. We did not make any comparisons with other national or international chapters of the movement..

This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. Theprojects main purpose was to develop a draft design of a test equipment. The equipmentwill simulate and valuate the drive-train and brakes at Kalmar?s bigger forklifts.The equipment will be designed so the wheels of the forklift are placed on two rollers;these absorb and affect the forklifts brake- and driving force. With this characteristic anup- and downhill can be simulated.

When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.
