Test och verifiering av en ny inkapslingsmetod för SiC BJT och MOSFET
The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..
I mötet mellan tradition och förändring : Om Wikipedia som encyklopedi
This study is about Wikipedia which defines itself as a free online encyclopaedia. Our chief interest lies in the debate and the controversy which has arisen around Wikipedia. After reading critical articles concerning Wikipedia we found that the debate for most parts had one identifiable theme namely the question whether Wikipedia is an encyclo-paedia or not.Encyclopaedia as a term and a phenomenon has a long tradition. Wikipedia, despite calling itself an encyclopaedia, functions differently in comparison to more traditional encyclopaedias. These traditional views involve encyclopaedic structure, its organiza-tion and its functions.

"Pojkar blir på ett annat sätt än flickor ett ordningsproblem i klassrummet" : En intervju-undersökning av diskursen om pojkar och flickor i behov av särskilt stöd
This paper examines how remedial teachers and subject teachers in two secondary schools talk about pupils with special education needs (SEN) both in general, and more specifically about boys and girls who need special education. The study is based on 6 interviews with teachers in two secondary schools in the Stockholm area. In the analysis of the interviews, two different theories have been used. Firstly, the teachers´ speech has been analyzed based on three perspectives; a compensatory-, a critical- and a dilemma perspective (see Nilholm, 2007). Secondly, discourse analysis has been used to examine how the teachers in the study talk about boys and girls in the special education.
Dyslexi : En studie om elevers erfarenheter av undervisning och psyko ? sociala förhällanden i skolan

I present previous resarch on this subject and I focused on docu drama and dramadoc. Bo G Jansson is the researcher I used most frequently in this essay. He describes various types of faction texts in film, television and literature. Annette Årheim´s thesis stands for the didactic portion of the essay.
Utveckling och tillämpning av det muskelstyrda datorspelet EMG Track Game.
Electromyography (EMG) is a technique that measures muscle activity, whichmeans detecting the electrical signals that travel through the muscle in connectionwith muscle contraction. This project deals with how EMG can be used tocontrol a computer game.The project is centered around the game 'EMG Track Game' which has beenconstructed as part of this work. 'EMG Track Game' is controlled by twoelectrodes fastened on the player. These are attached to two selected musclesand control the motion in one direction each, one up and the other one down.The game is constructed in the purpose of being used in several elds of application.Among these are as entertainment, training equipment and a tool inresearch related to EMG and muscles.To highlight a possible application a study concerning muscle control has beenconducted. It answers the question of whether players score better with theirdominant arm in comparison with their non-dominant one.
"Lite snyggare, lite mer partyaktiga, lite mer Paradise" : En kritisk diskursanalys av kön och sexualitet i Paradise Hotel
The purpose of this thesis is to examine how power structures concerning gender and sexuality emerge through the use of language in the Swedish reality show Paradise Hotel. Of particular interest is the representation of heterosexual relations in the show. Because of its interest in the relationship between power, gender and sexuality, the thesis is based on theories from gender and discourse studies. The specific theories referred to are Michel Foucault?s understanding of power, stereotypes according to Stuart Hall, Yvonne Hirdman?s gender system and contract theory, Judith Butler?s heterosexual matrix and R.W.
Kommunikationsverktyget intranät
AbstractThis report discusses how the intranet as a communication tool can bedeveloped to become a daily work tool. An intranet can help the organization to get information out to the employees fast, and the employees can choose when they want to take part of the information. This report also discusses how the functions and the presented information can be developed to be even better. The proposals has been developed out from information gathered from a survey,the people who has answered the survey has been given their point of view of the intranet, and also proposals for improvements, which we have implemented in to our theory part. There is no company or organization that uses the exact same intranet solution.
CSR utan gränser : En studie av oljebranschens reaktion på oljeutsläppet i Mexikanska golfen
Företag publicerar allt mer information om deras sociala miljömässiga och ekonomiska ansvar.Denna information presenterar de i sina årsredovisningar under avsnittet Corporate Social Responsibility. Idenna studie undersökt har vi undersökt hur rapporteringen i en bransch påverkas efter en incident och omdet finns spridningseffekter och imitationsbeteende när det gäller CSR-rapporteringen. Som utgångspunkthar vi valt incidenten i Mexikanska golfen den 20 april 2010. Då skedde ett stort oljeutsläpp i sambandmed att oljeföretaget British Petroleum's plattform Deepwater Horizon exploderade. Oljeutsläppet varomfattande och hade stor effekt på BP's rykte hos allmänheten.
Simonsontekniken i gymnasiets estetiska program med inriktning dans : En kvalitativ studie om anatomi och dansteknik
I denna studie undersöks danslärares och danspedagogers uppfattning avSimonsontekniken och hur den kan användas i dansundervisningen på gymnasieskolans estetiska program för att öka måluppfyllelsen gällande målen inom anatomi, kroppens funktion och den egna kroppens funktion enligt Gy11. Studien är en intervjustudie där gymnasielärare och pedagoger med erfarenhet av Simonsontekniken intervjuades.Resultatet visar att anatomi, och hur de förhåller sig till anatomi, är en viktig aspekt i deras dansundervisning. Ett framgångsrikt sätt att förstå anatomi är att integrera det i dansen istället för att endast behandla det teoretiskt. Det är även viktigt att skapa medvetenhet och förståelse kring varje individs kroppsliga förutsättningar..
FORL : Feline Odontoclastic Resorptive Lesions
This report was written in an attempt to summarize old and new theories and scientific
results regarding FORL (Feline Odontoclastic Resorptive Lesions). Several different kinds
of treatment are presented in this study. Among them teeth extraction and crown
amputation seems to give the best long-term results. It seems clear that the domestic cat of today have no trouble digesting dry foods without their teeth. The most accurate way to diagnose FORL is by using intraoral dental radiology technique.
Likabehandling i praktiken. : Åtta gymnasielärares pedagogiska strategier för likabehandling i undervisningen.
Både rapporter från skolinspektionen och tidigare forskning inom skolan har visat att det är vanligt förekommande i skolmiljön att elever beter sig illa mot varandra. De svenska skolorna ska i dag ha ett likabehandlingsarbete där skolpersonalen ska agera vid varje incident där någon elev blir illa behandlad. I denna uppsats är syftet att analysera och jämföra gymnasielärares sätt att arbeta med likabehandling. För att uppnå syftet ställs fyra forskningsfrågor om hur elever beter sig mot varandra, bakomliggande orsaker till dessa beteenden, lärares metoder för att arbeta med likabehandling och skolans gemensamma likabehandlingsarbete. En fallstudie har genomförts med åtta intervjuade gymnasielärare samt en enkätundersökning i elevrådsstyrelsen.
Brottsförebyggande arbete i Karlskrona Kommun
Theft without break-ins has increased significantly in the last year of swimming, sports and leisure facilities in Karlskrona, more precisely 60%. Vandalism in the shape of graffiti is another common crime. The solutions are divided into social and situational crime prevention. Social crime prevention engage in actions that are based on social causes of crime rather than the opposite situational crime prevention, which instead assumes that discourage with the help of technical solutions and has as primary objective to hinder accessibility for example theft friendly goods. The main purpose of this work is to come up with solutions to prevent these crimes, while also being cost-effective and realistic to implement.
Att se världen i svart och vitt : En kritisk granskning av SOS Barnbyars reklamkampanjer
The purpose of this thesis is to do a critical review of the aid organization SOS Children?s Villages text- and video campaigns, from a postcolonial perspective. Our purpose is divided into two questions: Are there colonial values in the advertising campaigns? Which language- and image strategies are used by SOS Children?s Villages to put across their messages? Our material consists of 10 selected video clips, and four printed ads that are made up of an image and a short text, which are part of a campaign named: Inte ett enda barn ska behöva vara ensamt (translation: Not a single child should have to be alone). We have chosen to use text- and image analysis as a method in our review of the material.
Systemanalys flingtork : Produktionseffektivisering
BillerudKorsnäs is a leading global provider of primary fiber-based packaging materials and on Gruvöns Bruk in Grums, they have chosen to invest millions in the boiler at the facility to increase the total capacity of the factory. This results in the Pulp Flash Dryer at Gruvön being burden more, which makes it important that it is of great reliability and can be run with a high capacity. The reliability of the Pulp Flash Dryer at Gruvön is not as good as one could hope, which leads to reduced availability and production, as well as to increased maintenance costs. There are a number of different reasons for this, but all the casual links are not known.The purpose of this project was to perform a system analysis of the Pulp Flash Dryer to identify bottlenecks and the most critical parts from a capacity- and availability perspective. Appropriate methodology for the system analysis was used and would be used in a structured way to perform the analysis with data from the process and the maintenance system.
