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..

Rätt ordning på liv och lära? : En undersökning av stiftens tillsynsansvar inom Svenska kyrkan utifrån domkapitlens disciplinåtgärder mot präster och diakoner år 2006-2009

The study has shown that retailers in the mid-price segment differentiate their brand through developing a strong company identity around the brand.

By controlling the strategies on a central level the company can make sure that the stores are steered in the direction that the company wants them to be steered in, and also that they follow the positioning-concept. The company can also devote its efforts to working with its core value, which is service.

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.

Statliga turistbyråers marknadskommunikation : en jämförande studie om den Tyska och den Tjeckiska turistbyråns verksamhet på den svenska marknaden

In many of the world's countries, there is a national organization responsible for marketingthat country as a tourist destination. Through their offices, these organizations work towardsthe creation of effective strategies and a deeper understanding of local markets. Usingqualitative methods such as interviews, observations, and thematic analysis, we managed toinvestigate how the Czech and the German national tourist offices operate, and whatstrategies they are implementing to increase the volume of tourism. The study focused on theanalysis and comparison of the organizations' goals and communication channels.The results show that the investigated tourist boards operate in a similar manner with smalldifferences concerning choice of strategies and communication channels. These discrepanciescan be partly explained by differences in the organization's ownership forms and theconsequences that follow that fact.

Vaddå ekonomisk utsatt? : Tankar om ekonomisk utsatthet bland barnfamiljer med utländsk bakgrund i Växjö kommun

AbstractThis thesis is centered on the economic condition and background of immigrants living in Sweden, with focus on Araby, Växjö. To guide us through this enormous work we formulated research questions, which are:Why have foreigners (immigrants) a greater risk of becoming economic vulnerable? How does economic vulnerability effect families with children?What strategies do families adopt under hard economic conditions? What strategies does the society adopt in assisting families, by economic aid, that are economic vulnerable?  Our sample was from a school where we administered an open ended questionnaire to selected students and we also had a comprehensive interview session with ten families in the community so as to have a complete picture of their living condition and how they think people are economically vulnerable.We concentrated on the causes, consequences and strategies of how economic vulnerability is handled by immigrants in Sweden. In our analysis we found out, though our respondents? answers, that the causes of economic vulnerable are background, language, priorities et cetera.

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..

Möbius sekvens -Möbius sekvens samt effekter av leendekirurgi hos en person

Möbius sequence is a rare condition where affected cranial nervesoften lead to speech deviations due to reduced oral motor functioning. Thisstudy aimed to survey speech deviations, compensatory strategies and selfperceptionof speech in seven people with Möbius sequence, and to linkthese to oral motor function and intelligibility. Additionally, the immediateeffects of smile surgery were investigated in one person. The abovementioneddomains were studied instrumentally, perceptually and throughstructured interviewing. All participants displayed reduced oral motorfunction.

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.
