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.

Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.

"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.

?En kärlekshistoria vi alla drömmer om?: En analys av chick lit ur ett genusteoretiskt perspektiv

The purpose of this Master?s thesis is to examine how the gender system is described in chick lit. The analysis is based upon seven chick lit novels. The primary theoretical point of departure is Yvonne Hirdman?s theory about the gender system, the hierarchical order and the separation of the sexes.

Det händer bara andra, det händer inte mig. Tre unga tjejers upplevelser av att ha levt i misshandelsförhållanden

Today several things point to the fact that many young women are being abused and sexual harassed. Despite that there is no knowledge about how the girls handle the violence or how the battering affects them. For that reason the purpose of this study is to describe and give a picture of some girl?s experiences of being battered of men they have or have had a relationship with. In focus is also how these girls identities are affected of the battering.

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.

Suitability analysis of a reintroduction of the great bustard (Otis tarda) to Sweden

The great bustard (Otis tarda) became extinct in Sweden during the mid-19th century. Globally, populations have suffered dramatic declines during the past two centuries. Recently, local populations have stabilized or increased after hunting bans and conservation efforts. Despite positive trends the species is still classified by IUCN as vulnerable (VU), mainly due to withdrawals in the distribution. The limited distribution emphasizes the need for finding ?new? areas suitable for a translocation or reintroduction.

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.

Konkurrensbegränsning genom selektiva distributionsavtal inom den schweiziska klockindustrin

Sammanfattning Selektiva distributionsavtal används inom många branscher som ett sätt att reglera handeln med produkter och som ett verktyg för att selektera återförsäljarna. Det senaste året har dessa avtal kommit att nyttjas även inom klockbranschen. Det är en speciell bransch där varumärkena får allt större betydelse och det bidrar till en starkare position för de företag som äger och levererar produkter av de specifika varumärkena. Syftet med detta arbete är att utreda huruvida de selektiva distributionsavtalen medför en begränsning av konkurrensen och om så sker, vilka faktorer det är som skapar begränsningarna. Vidare har en diskussion förts om de villkor som nyttjas verkligen är förenliga med lagstiftningen.

Inte vet jag vad jag håller på med e. : En beskrivning av partikel-e i dellboskan i två delar. Distribution och funktion.

Denna uppsats syfte och mål har varit att undersöka distribution och funktion för den i dellboska partikeln e. Undersökningen utgår från material transkriberat dels från egna inspelningar, dels inspelningar från Swedia2000projektet. Analysen uppdelas sedan på två delar; en första grammatisk undersökning för att fastställa regler för distributionen, somgenomförs utifrån skribentens och informanters språkkänsla samt konkordansundersökningar. Dessa resultat ligger sedan till grund för undersökningen av partikelns funktion i diskursen utifrån definitioner av diskursmarkörer. Slutligen har undersökningen visat att partikelntroligtvis kan införas under begreppet final dubblering av negation, samt också kan definieras som en diskurspartkel med funktionen att signalera övertygelse om att det som sägs är riktigt, och något som inte bör ifrågasättas..
