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.

A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to Convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.

The aim of this study is to identify factors, which decide wheter you choose to commute with bicycle to work in the winterseason. The study is conducted in Umea, in the norhtern part of Sweden. The study is based on 509 answers from a webbased survey, conducted on municipal employees. The study has investigated which factors that affect different commuting groups from a gender perspective. The groups, which has been compared is motorists, wintercyclist and summercyclists.

Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and Convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.

Development and construction of an electronic Breakout box is the main work for this thesis. The box is a part of a test system for the component Fuel Flow Transmitter and should Convert signals to be suitable for a frequency counter. A previously constructed Breakoutbox for this purpose is being old and needed to be recreated. So SAAB Aerotech, Aircraft services, the company for the thesis work wanted to construct a new, more sustainable Breakoutbox adapted to a more modern technology. The signals to the box comes from the transmitter and should be Converted to suitable signals for a frequency counter so it can show pulse and time difference between the signals.

The intention of this study was to create an understanding of how multi-professional interaction could Convert into inter-professional collaboration, which takes advantage of and acknowledges the individual professional identity. The intention was to understand the meaning of collaboration through the study of meetings between professionals who use different symbol systems. In particular, we wanted to study inter-professional interaction from a symbolic interactional perspective with a focus on Self, Identity, Symbols, Meaning and Professional community. The employed method was semi-structured interviews with ten questions. A convenience sample was used to identify working groups composed of different professions, such as teachers, social workers and therapy assistants.

The purpose of this comparative study is to investigate if the views of Sayyid Qutb and Tariq Ramadan regarding social structure and religion are possible to unite with western liberal democracy. The basis of the study is the problematizing approaches written by Qutb and Ramadan regarding the possible unity between Islam and democracy. These problematizing approaches are then tested on the political philosophy of liberalism to see if a unity is possible.The result showed that Qutb's view did not meet the criteria of democracy, which wasn't surprising due to his negative views on the system. However, Ramadan's reformist view on Muslim identity did unite with the views of liberal democracy, though questions regarding the possibility of creating and preserving a European Muslim identity in the secular society were immediately brought to attention.The importance in Qutb's view is social equality, unity and submission to God and the importance of Ramadan's view is to create and preserve a European Muslim identity and adapt to the society where you live and participate as a citizen. Qutb's view will not tolerate diversity and one is to keep or Convert to the Muslim faith.

AbstractThe aim for this study is to establish how teachers and supervisors at the Child and Recreation Programme interpret the concept ?vocational knowledge?. It is also about how they substantially can see that the pupils are developing vocational knowledge, during their work placement training. The aim of this thesis is to create a base for teachers to work with continuing development in teaching practice. The empirical part of this study is based on interviews. Interviews were analyzed in three categories: definition of vocational knowledge, substantially developing in vocational knowledge and success factors. The result shows that knowing how and knowing why is salient in vocational knowledge.

The purpose of this thesis is to examine the conflict of interest between shareholders, life insurance companies and insurers in stock life insurance companies operated on a mutual basis from an agency-theoretic perspective. Further, this thesis aims to explore from an ownership-theoretical perspective, why this conflict of interest exist. A qualitative research has been performed and the empirical data is foremost based on interviews with persons from the life insurance industry and public prints. The study concludes that the stock life insurance company operated on a mutual basis has two principals whose interests are in conflict. History has shown that stockowners? interests have been prioritized on the expense of the insurers.

That many creative workers have uncertain and uneven incomes is well-established, but how or why they make a living is not. This paper examines the elusive value exchanges between creatives, buyers, consumers, and other economic supporters, and offers a model of how creatives make a living. By mapping income statistics of Swedish creatives together with in-depth interviews some patterns emerge. This, combined with Bourdieu's theories of social, cultural and symbolic capital, and Knorr's objects of sociality, forms a basis for a structured model of value exchange. The paper shows how creative workers create economic and non-economic capital (capitalization), how they advertise this capital (signaling), and how they Convert between different types of capital (conversion) in order to make a living.

This thesis seeks to investigate the relationship between municipal policy for housing supply and the planning of new housing in Sweden. Through a case study of Göteborg municipality and a comparative content analysis of Göteborgs policy for housing supply and a number of plans featuring housing the analysis seeks to investigate the effect of policy for housing supply as a tool for securing the demand for housing in the Swedish municipalities. The thesis also seeks to discuss its findings using theory concerning the implementation of policy and the general planning situation for Swedish municipalities today. The result of the analysis shows that most plans fail to regulate most of the content suggested in the policy for housing supply, particularly regarding aspects such as pricing, type of housing and type of ownership. The result also points towards a relationship regarding the prevalence of municipal land contracts and compatibility to policy for housing supply as well as a connection between how extensive the plans are in their proposed land use and their compatibility with policy for housing supply.

Hence, the system shall be used both to Convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

The purpose of this study was to examine whether urea could be an option as a nitrogen source for young cattle, the study was limited to risks related to feeding, growth and feed efficiency. Microbes in ruminants have the ability to Convert nitrogen to protein, this has been highlighted by beef producers as they are in search of cheap protein feed resources. Urea can be a worthy source of nitrogen for growing young animals, because of its high nitrogen content and the low price. Studies have shown that the replacement of a portion of the total protein content by urea in diets with low content of crude protein, like corn silage, may improve animal growth and feed efficiency. Replacement of all the true protein with urea can result in reduced feed intake and microbial growth.
