The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

In this thesis you will be able tofollow the design work of a drumtest. A tool that by having a rotatingdrum with equally positioned obstacleswill simulate the conditions a mountainbike rim will pass through.Initially there is a specification ofsome parameters and requirements thatthe design had to fulfill. There is alsosome brief background information aboutwhy a drum test is required for abicycle rim manufacturers and about thecompany Innolite Design AB that thisthesis is done for. After that itfollows an extract from conceptgeneration with the chosen concepts andsolutions but also some of the conceptsthat were not chosen.The thesis also contain a part where thereader cangain a deeper understanding of how thedesign works as well as some moredetailed facts about how the choice ofmaterials, their thicknesses, etc. havebeen made.

Detta arbete beskriver struppipning, som är en sjukdom som beror på att rekurrensnerven är skadad. Detta leder till att larynx inte kan fungera normalt. Hästens symtom visar sig särskilt vid ansträngning, då den blir onormalt trött, och vid inandning har den ofta ett karakteristiskt missljud. Orsaken till att nervskadan uppstår är ofta idiopatisk, men det kan exempelvis också bero på trauma av olika slag. Det är troligt att sjukdomen är ärftlig.

ABSTRACTThe aim of the study was to examine the prevalence and the location as well as the registration of gingival recessions among patients between 20-29 years of age, who are treated on the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a recording study, where the first page of the base record paper was examined. We examined 295 base records. The result showed that gingival recessions only were registered on 3 % (n=10). Most of the injuries, 53 % (n=157), had been registered as toothbrush trauma.

In this thesis I am going to study how women experience working in a male-dominated occupation and how men experience working in a female-dominated occupation. I have chosen a qualitative method, interviewing four women and four men. By using this method I have gained a deeper understanding of what it is like having a non-traditional occupation. In the background I have looked into the unequal distribution of power between the sexes as well as the entrance of women on the labour-market, where the law of equality has had a major impact on the strive towards a more equal distribution according to sex. The theoretical part includes different theories where gender is focused, both when it comes to the biological differences as well as the segregation of sexes that prevails in society and here socialization heavily influences the choice of a vocation.

To achive this purpose I have used following questions: Which view have preschool teahers about the inportance of aestetic forms of expression for children? How do preschool teacher describe their work with aesthetic expression and what similarities and differences exist between the different pedagogical approaches? The result shows that there are both similarities an differences between the preschools, mainly how they work with aestetic forms of expression.

The purpose of this this thesis is to evaluate the books that the Library Project "Give me five" uses accoring to their own project objective. Starting in the discussion of censorship that took place in Swedish media, the goal of the project is to defend picture books that portray child's inner and outer worlds. Some of the books are selected by librarians and some preschool teachers themselves have chosen. I have a in a thematic analysis examined if the books' themes meet the requirements of the project goals and if there is any difference on the books that preschool teachers chosen and the ones that the librarians have selected. I have in a image analysis investigated whether they have used books that challenge children's imagery, and if the books portray children's outer world.
