Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Usability is a way to study how good a website is which is what our research builds upon. On a mission from Liseberg our purpose is to find out if their website liseberg.se is good from a user?s perspective. Our way of carrying this out where grounded upon a qualitative study through observations and following interviews with a number of participants. By compositing tools of method we have started with the theories descriptions of usability tests and we have also used the theories to be able to reflect around and to understand the results from the tests.

Smarta elnät är en av lösningarna för att uppnå EUs klimatmål den s.k. 20-20-20-satsningen. Klimatmålen innefattar bl.a. ökad energiproduktion från förnybara energikällor och ökad energieffektivisering, detta anses nödvändigt för att hindra den globala uppvärmningen samt uppnå en bättre och mer hållbar framtid. Den elektriska energins svaghet är den begränsade möjligheten till effektiv och storskalig lagring. Eftersom den förnybara energin har en väderberoende produktion ska smarta elnät hjälpa konsumenten att styra energikonsumtionen efter hur energiproduktionen varierar.

The field of coping has become more developed during the past decades but there is still a lot to be discovered and discussed. Theories of developmental psychology describe the possibility to map a general developmental structure of how the human mind expands. The aim of this study is to contribute to further research in whether there is a reason why we cope the way we do in relation to age. The questions answered in this study was, what coping two girls, whom lived during the Holocaust, used and how the coping found, were possible to interpret from theories of developmental psychology. In order to answer the questions asked a method called Template Analysis Style and three different theories have been applied.

This thesis presents the results of the implementation and evaluation of two machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi cation methods. The results of the evaluation did not match those obtained by the original authors.

The main purpose of this study is to take a closer look at how teachers work with writing and to examine some theories on the teaching of writing. Five teachers in two schools are included in order to get an insight in teachers? practical work with EFL writing. This has been done through classroom observations and interviews. The results show that all teachers seem to use aspects from several theories.

Virtual communities are a phenomenon that is becoming more common as the information technology comes with in reach for the general public. This report will bring the theories and construction of a virtual community together. The purpose of this report is to describe the different theories that have emerged from the research within this field and to examine the work procedures that have been used during the development of a site for a MDA-community. The MDA-website is a homepage on the Internet that was developed to bring the students closer together. The report describes the work of the project group, why the website was not completed and at the end the theories are looked at on the basis of the construction of the website..

This study illustrates the task of the administrator where the main focus lies on getting understanding for the administrator?s work, showing how this is performed. The method I have used in the performance of the research is the qualitative method. This study was carried through by means of interviews. Theoretical starting points are exchange theories, friendship theories and part theories.

The banking industry is a fundamental part of the economy in Sweden. Despite its importance, the competition and the concentration level within the Swedish banking sector is relatively unexplored. This paper aims to examine the development of the concentration level in the Swedish banking sector during a period of ten years, 2003 to 2013. The examined banks in the study are the four largest banks in Sweden; Handelsbanken, Nordea, SEB and Swedbank, and four selected niche banks, ICA banken, Ikano Bank, Länförsäkringar Bank and Skandiabanken. In order to examine the development in percentage change, there are six selected variables; loans, deposits and borrowings (both public and households), net interest income and return on equity, which are observed during a period of ten years.

Exporten har en betydande roll i dagens samhälle och verklig påverkan på landsbygden och dess framtida möjligheter till överlevnad i ett urbaniserande och teknikfokuserat Sverige. Det är dock inte helt enkelt som enskilt, mindre företag att exportera sina produkter. Detta arbete syftar till att lyfta fram framgångsfaktorer hos livsmedelsföretag som redan är väletablerade på den internationella marknaden och som under en tid har bedrivit en framgångsrik exportverksamhet. Det är en kvalitativ studie och det empiriska materialet är baserat på tre semistrukturerade telefonintervjuer med livsmedelsföretag från Halland och Skåne. Begreppen resurs, nisch och ??Dynamic capabilities?? samt ramverket VRIO har varit viktiga vid analysen.

The overall purpose of this study has its starting point in theories about the consuming society and its advertising. I have examined what kinds of methods that are being used in TV-commercials for beauty products, to influence the consumers. To study advertising, a semiotic method, symbolic interactionism and other theories which discuss symbols and influences, have been used. Six different TV-commercials for beauty products have been examined.The results from this study indicate that the advertiser apply to feelings such as, happiness, a sense of satisfaction, status and success, to affect the consumers behaviour. The findings in this research are discussed in the light of different theories which deal with the significance and the meaning of symbols..
