This is a report written for an examination project C-level, on the subject of energy. The examination project is a product of the FVB Sweden AB (district heating bureau). It started with a meeting with Stefan Jonsson FVB Sweden AB, were he explained the content of the project, and from this a presentation of the problem was made. The problem that needed to be solved was how they could control the valves in the system to provide heating to everyone in the system. The valves are often oversized so the pump in the heating plant would have to be enormous to be able to provide enough flow to be sufficient, if everyone in the system had there valves fully opened. I came up with two solutions to the problem, one was a wireless network that could keep track of the valves and the other solution was an extra sensor that was placed on the radiator.

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

This is a qualitative study about Art transformation and commodification in the digital age. The study applies a rhetoric analysis with the aim to understand how art sellers, gallery owners and entrepreneurs take part in this transformation process through their websites? presentation texts ?about us?. The analysis is related to communication theories but it is also inspired by other theories such as Gramsci?s hegemony theory and Bourdieu?s cultural critical theory.

In this thesis I have used post-colonial theory to analyze the Uyghurs, a Muslim minority group located in Xinjiang province in the Northwest of China, and their identity shaping process in relation to the dominating Han Chinese. I have analyzed the possibilities to use the power perspectives in post-colonial theory, especially Edward Said's Orientalism and the creation of the Other in a new context, where the main focus is on the Uyghurs through the eyes of Han Chinese. I have argued that Han Chinese, with colonial tendencies, have created two generalizing pictures of the Uyghurs; one romantic picture to use as an exotic tourist attraction and one threatening picture that portray Uyghurs as Islamic terrorists to win support in international politics. The thesis is a qualitative single case study with the aim of gaining a deeper understanding for the Uyghurs as well as examine possibilities of widening the analyze areas for post-colonialism. My conclusion is that the power perspectives in post-colonial theory are usable implements also for non-western contexts and in this case function as a way to understand the identity shaping process for the Uyghurs and their relation to Han Chinese..

In this thesis I analyse civilizations in South America. I construct civilizationalnarratives through the method of emplotment, to build a historic continuity, whichI subsequently connect to the theoretical framework. The theory emphasise that,when confronted with globalization and free market capitalism, civilizationsembark on different strategies to challenge the power of transnational marketforces. I find that South America is a polarised continent, and is divergingconcerning the relationship towards the USA and free trade agreements. On thesame time the issues that concern the social movements are not being reproducedin a significant matter at state level.

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.

In this thesis I have done a discourse analysis of the documentary movie A Jihad for Love. A Jihad for Love came out 2007 and is directed by Parvez Sharma. The documentary movie is about homosexual Muslims and their jihad, struggle, for love and to be accepted in a world where they are barely recognized as a group. My aim of the thesis was to see how the movie portrays the persons who are in the film and their relationship to Islam and who gets access to the religion. I have also analyzed if Islam can be used to strengthen the sexual identity or if it works in the opposite way.

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

The fishing port of Bläsinge is located on the east coast of Öland, Sweden?s second largest island. Today the port has a limited supply of freshwater. The economic association of the fishing port wants to expand their business, so that they will also include tourist services. To do this the harbor will need a more independant source of freshwater, with a higher quality than the present well.

Our purpose with this essay is to find explanations to the genesis of the Swedish law against prostitution now in power, known as Sexköpslagen 1998:408. We enter deeply into the official reports behind the law. This Swedish law implies that in a sex trade a crime is committed only by the consumer, and not by the seller. Our essay will result in an analysis of what sexköpslagen is an expression for. Our assumption is that the so called ideology of (gender) equality in Sweden might be a part of the explanation to the genesis of sexköpslagen.

Youth unemployement in Sweden is at an all-time high, a fifth of all university and college students live in poverty and the number of young on welfare is increasing. This study attempts to answer the question of how youth deprivation has been made possible as a consequence of political action, focusing on youth unemployment.I critically examine the role of the Swedish government, the Swedish Labour Organisation (LO), and the various government departments through text analysis, in order to answer the question of how the current discourse on youth position in the labor market. Because youth unemployment is not an isolated phenomena the analysis covers several policy areas, such as education policy, labor market regulation and housing policy. I use discourse theories drawn from Laclau and Mouffe to expose how language is used as an instrument of political power.I conclude that the current situation is a result of policy choices where the young have fallen behind due to lack of political organization. Their situation is not problematized to the required degree and is often explained on an individual level rather than on a structural level..

Media has an influence on millions of people around the world, this influence can be positive as well as negative as a consequence of how phenomena and a certain event are interpreted. Mass media tend to magnify and dramatize events in form of attractive headlines in order to get as many readers as possible. One of the countries that the media spotlight focused on in recent years is Greece. However these attractive headlines, have not contributed anything positive for the country and one can say that it has done more damage than good. In the media the Greeks have been stereotyped, radicalized and labeled as "lazy" due to the representation of media.

The Swedish society woke up Boxing Day 2004 to the greatest disaster in modern times. As a result of a strong earthquake in the Indian Ocean tsunamis occurred that devastated resorts where thousands of Swedes were. In the disasters tracks were uncovered government paralysis and shortcomings of the systems control. The purpose of this study is to examine the capacity and means to demand accountability of politicians and officials of the Swedish political system. Extensive studies and the report from the commission of disasters will form the basis for the study.

The voltage level in the power grid varies due to variations in load and production. Normally these variations are manageable, but they may be excessively large during a disturbance. If the voltage is too high it may damage the equipment in the grid and too low voltages may cause problems like voltage instability. The magnitude of the voltage variation depends on the short circuit power capacity of the point of interest.This problem may become lore prominent due to automatic voltage regulation that acts on shunt reactors and shunt capacitors. When the shunt reactor is connected or disconnected to the grid it may cause such large changes in the voltage that the shunt reactor starts hunting.

För att utöka ett fordons användningsområde kan det utrustas med olika typer av arbetsredskap och lasthanteringsutrustning. För att driva dessa finns möjlighet till kraftuttag (PTO - Power Take-Off) från ett antal anslutningar vid motor och drivlina. I dagsläget saknar motorns styrsystem information om dessa laster vilket kan påverka styrningen negativt. I detta arbete presenteras en metod för att estimera det okända lastmomentet på kraftuttaget. Metoden utgår från Newtons andra lag för svänghjulet och det drivande momentet till drivlinan beskrivs av en dynamisk modell.
