Förstudie för kvalitetssäkringav glidande förband vid Hissmoforsvattenkraftsstation : -Specifikt för aggregat G6 och G7
Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..
Om detta är en psykiskt funktionshindrad. : - Diskurs, makt och subjekt i psykiatrireformen 1995
This study aims to investigate the political reformation of the psychiatric care in Sweden, that took place 1995. The main purpose is to illuminate the transformation of subjectivity for mentally ill people after the reform 1995. The group of people which are present in the study are those who former were subjects of care in psychiatric hospitals, but with regarding to the reform have moved out from the institutions and instead become clients for community care. This new group of mentally ill people became, in connection with the reform, subjects for a new concept psykiskt funktionshinder. This new label and concept, that were attached to the present group, is the main concept for the investigation in the present study. The method, that was used in the study, develops a textual based analysis of the official documents, that were produced in connection with the political decision to reform the care of mentally ill people. With a theoretical conceptuality taken from Michel Foucault, with concepts such as discourse, power, and subjectivity, are the documents analysed in order to illuminate how the new subjectivity, under the concept of psykiskt funktionshinder arise.
"Varför är du här? Du kan ju inte dansa!" En uppsats om funktionshinder, annorlundaskap och makt
This essay is a qualitative study concerned with questions about disability. I set out from a definition of disability which highlights non-disabled peoples´ participation in making a disabled person ?the Other?. My aim is to contribute to an understanding of the experiences of disabled people as well as problemize the way that normality and disability is socially constructed. The empirical material of the essay consists of qualitative interviews with disabled men and women and the essay is written with a critical perspective.
Aerodynamisk optimering av vindkraftverks rotorblad med en genetisk algoritm, BEM-teori, och XFOIL
This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.
Back to the USSR : En studie av Rysslands demokratiska urholkning
Abstract:The purpose of this study is to examine what actually makes Russia an incomplete democracy, despite of all the formal democratic institutions and legal democratic rights.The research method used for this essay has been qualitative case study, which strives to answer two research questions: Which democratic principles are not respected in Russia? How does the executive power control the political arena? The theoretical framework used for this study consists of a model based on Dahls Polyarchy theory and the Rule of Law concept. The conclusions points out that very little have formally changed in Russia regarding democratic rights and the constitution. The democratic decline is due to political manoeuvres and undue political influence. There is no proper division of power and the executive powers are not controlled by a system of checks and balances.
Analys av designalternativ för snabbare dynamik i kolkraftverk med koldioxidavskiljning
Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.
Asymmetri - ett förräderi?
This study aims to disclose how an asymmetric planogram structure of the brand with the highest actual variety may come to affect the brand itself and its category as a whole. The authors of the study feel that there is a gap still unfilled amongst previous extensive research examining how differences in either space or price vary between categories, products or brands. An in-store experiment was conducted by collecting quantitative data from daily sales, observations of customers and questionnaires. The results show that an asymmetric structure leads to customers being more attentive towards the brand, and perceives it to be more dominant over its surrounding competitors. Furthermore, results indicate that the customer perceived variety increases and we see tendencies to changes in sales..
?Nu kör vi!? : En kvalitativ studie kring fördelar och nackdelar med en traditionell dansundervisning
There is respect for the history of dance and my aim is to find out how the history affects the dancing youth today. The design of the dance lesson is often of a traditional stereotypical manner, both didactic and methodic, and it rarely appears to be questioned. I have danced for almost 20 years and I am a part of this tradition of movements, music, language and way of ?being?. My ambition with this study is to go outside my own experience and offer insight and an overall picture of a, for the outsider, closed world.
Datadrivet generellt partikelsystem till NeoEngine och Power Racing
Arbetet har utförts åt Power Challenge AB som utvecklar onlinebaserade spel. Partikelsystemet är utvecklat att kunna användas oavsett spel, men effekterna som skapats i detta arbete är riktat till ett racing-spel. En generell uppbyggnad har underlättat konfigurationen av olika parametrar avsevärt. Det har också medfört skapandet av en editor där det går att skapa nya effekter samt spara ner konfigurationen för dessa..
Expanderande universum : Den amerikanska serieindustrins superhjälteuniversum och islam.
This study examines how the American comic book industry?s output is addressing the issue of Islam and in which manner the portrayal of Islam in the great American comic book universes have changed since 2001. The comic books are examined from the postcolonial perspective as formulated by Chandra Mohanty and the power and resistance-perspective as formulated by Michel Foucault. Examination of the comic books reveals far greater focus on universal values, orthopraxy and inclusive perspectives than it does on dogmatic teachings, orthodoxy and sectarianism while at the same time partly relying on generalizations and archetypes concerning Islam. To change the power balance requires what I call intervention from the objective, that is to say that ambiguity regarding Muslim characters has to be eliminated by the narrative.

Lån utan säkerhet
The Swedish market for unsecured loans has frequently been attacked by media and government officials. Some actors have been accused of exploiting customers and charging inappropriately high interest rates. Despite the public interest very little academic work has been published on the topic. Therefore it is our purpose to investigate why the prices can differ so much between the different actors. Further, we also aim to conduct a market overview as a secondary purpose which will help us in reaching our primary purpose.
Operation Rolling Thunder
This paper provides an explanation of the concepts John A. Warden III describes regarding the use of air power and if this theory can be found, within the confines of an unconventional war. The U.S. ability to air power is overwhelming, however the right kind of warfare can force this great power to abandon their military and political objectives by exhausting its resources over time as it becomes increasingly costly, both economically, politically and morally, to wage war. The research deals with operation Rolling Thunder and John A.

Skadeanalys och omkonstruktion av HMS Belos A-ram
In order to rescue a distressed submarine crew, the Swedish Navy is able to use a deep submergence rescue vehicle, DSRV. This mini submarine ascends, docks to the downed submarine and picks up the whole crew. The submarine rescue ship HMS Belos has a special crane located in the aft of the ship to lift the surfaced DSRV aboard, which then docks on to the on board pressure chambers located below deck. During inspections the aforementioned crane has shown to have problems with cracks in the structure, most of them located in the bolted joint between the top part of the crane and the two leg parts. A simulation of the forces acting on the structure in heavy sea condition was conducted; these values were then used as input values in a Finite Element Method, FEM, analysis of the joint.
