The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

The following essay aims to determine what textbooks and teaching media educators in the county of Västerbotten use when teaching the relation between religion and science. Based on educational science theory and through analyzes of factual texts, the teaching materials was examined to determine how much focus they put on the thematic of religion and science. The result shows how the different teaching materials affect this thematic differently. The main conclusion is therefore that students in Sweden could, depending on the teaching materials used in their education, be taught by different standards to reach the same requirements..

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

The thesis is aiming to investigate what happens in the customer-service worker interaction when the service worker is wearing religious attributes. In order to operationalize this the Muslim head scarf, hijab, is chosen as stimuli. Reviewing previous research and theory in this field, it is clear that people have a preference for people that they perceive to be like themselves, this is referred to as homophily. Further on, the study investigates the ethnicity dimension of the service worker customer interaction. Theoretical areas of attractiveness and color are also investigated.

I uppsatsen undersöks hur 11 globala miljö och/eller etiskt märkta fonder har presterat i jämfö-relse med 17 konventionella fonder i det svenska premiepensionsutbudet genom tillämpning av utvalda finansiella prestationsmått. Detta med anledning av att miljö och/eller etiskt märkta fonder har haft en stor framväxt under det senaste decenniet och det finns därför en efterfrå-gan av att klargöra ifall en pensionssparare behöver göra avkall på den finansiella avkastningen vid val av miljö och/eller etiskt märkta fonder. En jämförelse av det statliga förvalsalternativet och 10 globala miljö och/eller etiskt märkta fonder har även gjorts för att undersöka skillnaden av att vara en aktiv respektive passiv premiepensionssparare då antalet som inte gör ett aktivt val är omkring 50 procent. Resultatet visar ingen statistisk signifikant skillnad med avseende på den riskjusterade avkastningen mellan fonder som är miljö och/eller etiskt märkta och fonder som inte tar hänsyn till dessa kriterier vilket överensstämmer med tidigare forskning. I jämfö-relsen mellan det statliga förvalsalternativet och 10 globala miljö och/eller etiskt märkta fonder har det förstnämnda presterat på en hög nivå..

During the period after the Second World War Sweden underwent a quick transformation due to a strong economic development. Decades-long rule for the Social Democratic Party now led to the creation, in Sweden, of a modern welfare state. This period in Swedish history is often considered to be the time when ?the Swedish model? was formed. Tage Lindbom (1909?2001) was a historian and intellectual in the Swedish labor movement.

Research shows that almost 30 per cent men and 20 per cent women at the age of 16-24 inSweden download music on a regular basis instead of buying records. Thanks to moderntechnologies teenagers of today have become used to downloading music illegally from theInternet. Even though legal alternatives, such as Spotify, have become popular, the behaviorof illegal download of music still persists. What do record companies do to prevent thisphenomenon and why do they go to such length to stop this widespread movement? Thequestion is, why is illegal download of music a problem ? and for whom?To investigate this I?ve read books about the subject, analyzed web pages of alternative recordcompanies and interviewed a drummer in a local band.

This thesis looks at the difference between the legal protection in law and the legal protection in reality when a small company working with international trade comes in contact with seller's breach of contract. The thesis uses a case taken from a company with over 30 years experience trading with China and looks at the legal protection available along with the different possibilities of dispute resolution available to a company and then looks at the reasons why this legal protection never becomes a reality and the thesis also analyses some possible reasons for this gap between law in the books and law in reality..

The purpose for this Masters thesis is to describe childrens librarians work in supplying literature to children with emphasis on easy-reader materials. Our main questions are: · What do librarians believe characterizes an easy-reader book, and what do they base their decision on when classifying a book as easy-to-read? · How have the libraries in our study solved the hands-on difficulties associated with easy readers childrens literature? · Which factors do librarians consider to be important when supplying literature to children that are not used to reading or are not good readers? The theories we have used are Aidan Chambers Reading Circle and Karner Smidts view on the librarians professional roles when supplying literature. We have used a case study method, which means that we have gathered information through observation, objective papers and interviews. This has been done at six libraries.

In this study, I examine how educators are working with gender. My focus has been on gender and literature. The questions I asked is how educators choose the books that are read in the preschools and if they discuss literature from a gender perspective? I used two methods in this study, observations and interviews. My main base of theory is Lev Vygotskijs? sociocultural theory.

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.

The aim of this thesis is to examine how the identity of the public librarianwith regard to reading is manifested in the library field. The approaches thatare taken to reading and readers are examined as well as the consequencesdifferent approaches might have. The empirical material is based on 93articles published in Swedish library journals. The theoretical andmethodological starting point is discourse analysis. The application ofdiscourse analysis according to Michel Foucault?s hypotheses reveals threediscursive formations regarding the professional identity of public librarianswithin the framework of reading promotion: The public librarian asguarantor of democracy is related to the public library's original mission offostering, cultivating and educating citizens.

This master's thesis is about alternative career opportunities for library and information science graduates. Ever since the beginning of our education we have been interested in working outside of the traditional libraries. Now that we are about to receive our degrees in library and information science we are doubtful if the competence we have obtained is enough to meet the demands of the labour market. The employment field we have been studying in this master's thesis is information management, since this is a field that we find comparable to library and information science. Our study involves a qualitative survey amongst recruiting companies to investigate how the recruiters value different educations, competences and personal skills when they employ staff within the field of information management.
