Vindkraftverk ansluts idag i snabb takt till elnät runt om i världen. Elnäten är ofta inte tillräckligt dimensionerade på platser där vindkraftutbyggnad är lämplig vilket leder till ett behov av nätförstärkning. Förstärkning sker konventionellt genom att övergå till en högre spänning, något som kan vara förenat med stora kostnader och ledtider. Bland annat därför har en filosofi med beteckningen smarta elnät uppstått, som handlar om hur elnätsystemet ska se ut när det är mer anpassat till de nya energikällornas karaktär och samtidigt medför ett mer effektivt totalutnyttjande. För vindkraftverk kan det då handla om att i högre grad än idag reglera produktionen och understödja nätet, t.ex.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

This thesis examines the everyday resistance, and its interaction with cultural hybridity, of the Saami population in the administrative unit of Torne lappmark during the period 1639?1732. To do this, the thesis uses theoretical concept of everday resistance as it has been described by JamesC. Scott and the theories of cultural hybridity as they have been described by Peter Burke. Primary source material used in this thesis consists of the court records from Torne lappmark, specifically from the courts at Jukkasjärvi and Enontekis.The results of this thesis present a picture of the everyday resistance in early modern Torne lappmark.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

Purpose?This study has examined the information behaviour and perception of information in a group ofinformation users who have a critical approach to the media and the information supply. Some of them call themselvesor are being called conspiracy theorists. The purpose was to examine how their information behaviour is influenced by the belief that the information is biased or inaccurate and what the information behaviour looks like when the user searches for discrepancies rather than a response to a question.Method?The study is based on transcribed interviews and email responses to interview questions.

Today?s environmental discussions have led to more progress in the different transportareas. To ride a bicycle is often one of the most efficient alternative when it comes totransport. An Electric bike is, and makes transportation more efficient than a regularbicycle. Electric bicycles do not affect the environment significantly and allows moreconvenient transportation than ordinary bicycles do.

This essay deals with the subject of the use of news medium amongst the students inKarlstads University. The presentation of the problem is about illustrating the or thosemedium that is the most used amongst the students, and also which one, ore which onesof the news medium the students puts largest trust in. This subject was chosen with thepurpose to illuminate patterns and attitudes of and to news medium, to make it easierfor eventual research in the future to connect these patterns and attitudes with theparticipation in political elections. The subject in question is interesting because of thefact that the news medium is one of the largest sources of information for the citizensknowledge?s about the society, and the citizen?s attitude to the news medium mightpossibly have the ability to affect people?s commitment in politics.

This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.

Abstract in EnglishElsa Grave (1918-2003) is a Swedish writer, artist and composer. The aim of my study is to analyse the female character in Mödrar som vargar, (Mothers As Wolves), which is a collection of poems written in 1972.The analysis is divided into four parts. First I analyse the figures of speech of the female ?I? in the poems. In the second part I`m dealing with how she acts and relates to men.

The number of data centers and their capacity is increasing throughout the world. Theenergy used in these data centers and the emissions from the use are increasing at thesame rate. The total use of energy will double from 2008 to 2011 based on the trends indata centers use. Research in this area says that the emissions from data centers willhave surpassed the level of airline traffic in 2020. The index used today to compare howefficient a data center is, called PUE, is lacking some information.

This report is the written part of a bachelorthesis on the computer engineering program atUniversity of Halmstad. The project was a cooperate project that where done together withFree2move Holding AB. Free2move is a company with eight employees in Sweden and four inMalaysia. The company is today developing Bluetooth modules and RFID chips. The market forthis kind of products is growing very rapidly, last year it grew 71 percent.

Titel: Fostran som pedagogiskt projekt. Bilden av ?problembarnet? i statens offentliga utredningar. (The bringing up of pupils as an educational project. The image of ?the problem child? in governmental committees).   This study focuses on the image of the problem child as it appears in two texts (from the 1940s and 1970s) of governmental committees on Public Health (SOU) and the new school law (Ds 2009:25, will be implemented in July 2011).

The aim of this study is to analyze the change of Basque nationalism during the last ten years and discuss how the main nationalist party (PNV) tries to impose "we"- feelings and support for its cause. Theories of nationalism and national identity are used in the analysis.A textual analysis of PNV:s unofficial documents is discussed and compared with a discourse analysis of its official documents. Although the unofficial documents deal with similar view of basic political/territorial ambitions, language and identification, there are some differences in the latest documents regarding the view of who is defined as Basque and also to the detoriated relation to Spain. Although references are made to the regard that the Basque Country is for everyone, the persistence of emphasizing the uniqueness and myths of the Basque culture signals a different matter. The discourse analysis of the official documents supports this claim and although they contain an ambiguous relation to Spain it is clear that Basque nationalism has been radicalized.

Swedish law (SOL 2001:45, LVU 1990:52) has gone through several changes to promote participation. The law also includes that young people should be able to participate even during a placement at youth detentions.  The aim of this study is to describe how young people at youth detentions are participated in their treatment plans. The questions of the study were: How and where are the young opinions produced in their treatment plans; how did the opinions change during the time in detention; and how have the opinions been considered at youth detentions? Participation is a wide concept with different meanings. The meaning of participation in this study is that youth have been listened to and that their opinions have been paid attention to.
