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.
Marin diplomati ur ett småstatsperspektiv. : Fallstudie svenska Ålandsexpeditionen 1918.
Abstract:The old established description gunboat diplomacy has in modern time changed to a broader and more nuanced definition called maritime diplomacy. But what is maritime diplomacy and how is it described? This essay analyses the theories from the Englishman James Cable and the American Edward Luttwak. Both Cable and Luttwak represent nations which have a global security interests and deploy their maritime forces worldwide. The foundation for their theories is power politics.
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.
Work locus of control och ledarskapets betydelse för anställdas målengagemang under en företagsnedläggning
Anställdas produktivitet har överraskande visat sig öka under tidigare nedläggningar. Detta uppmärksammade fenomen benämns nedläggningseffekten och förklaras bland annat av anställdas ökade autonomi och utrymme för innovativa förmågor under nedläggningsperioden. Relationer mellan ledare och underanställda är enligt LMX-teorin av olika kvalitét vilket kan förklara anställdas engagemang, ett engagemang som även kan förklaras av anställdas individuella differenser. Syftet med studien är att undersöka ledarskapets och personlighetsvariabeln work locus of control betydelse för anställdas målengagemang under en nedläggningsperiod. En enkätundersökning för 275 medarbetare utfördes 2006 på ett tillverkningsföretag.
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.

Statens fastighetsverk -betalformad styrning i en funktionsdriven organisation
The National Property Board (SFV) has been appointed by the Swedish government to administer all property of cultural value owned by the Swedes collectively. The commission includes maintaining the soul and character of each individual building, to adapt these buildings to present needs and requirements, and furthermore making them available to the public. The return on equity demanded by the government is based on the CAPM used within the real estate industry. The theoretical assumption that organizations are either function-driven or pay-driven will serve as a starting point, after which SFV will be defined as a function-driven organization with a pay-formed management control system. This paper aims to examine how applying a pay-formed management control system will affect a function-driven organization.
Kunden som varumärkesskapare
The purpose of this study has been to examine how customers, by interacting with each other, can communicate and create the image of a brand. We find this topic to be relevant since there are no previous studies conducted concerning the customers influence on the brand image. Our ambition has been to describe in what ways and to what extent the customer can affect and influence the brand image by communicating with other customers. To fulfill our purposed we have targeted three important questions which are:? In which ways can the customer affect the communicated image of a brand?? To what extent can the customer influence the brand image and the perceived value?? Who has control over the brand, the customer or the company?For this study we have used a qualitative approach in which we have conducted eight personal interviews with brand consultants and the editor of the magazine Dagens Media which has given us the foundation for our analysis.
Konstruktion av upprätningssystem för CICLoPE
Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

The school's equipped with an electrical bonding system, harmonic filters for the third harmonic currents, TN-S system from feeding transformer and groundfault monitoring.
Utbildningens betydelse för hälsan : En studie i skillnad på ohälsa mellan akademiker och icke-akademiker
The main focus with this study was to investigate if there was a difference in level ofeducation and self-rated health and if it could be explained by the amount of control,demands and social support at work. Theories used in this essay are education, health,and the job strain-model (control, demands and social support at work). We used analready done study by Folkhälsoinstitutet (2004) to examine these questions. Theanalysed sample consists of respondents 12 166 aged 18-84 years. The decline was39, 2 %.
En organisation i förändring. En fallstudie om Lantbrukarnas Riksförbund och riksförbundsstämman.
AbstractThe Swedish agricultural organisation, LRF, stands in front of many changes and the work with the changes in the organisation has caused some conflicts at the top. Is it like Michels say that it's a few people at the top that rules? The case with LRF shows to be something different, since the president Caroline Trapp was re-elected. The election committee proposed a new president, but the assembly had another opinion and re-elected Caroline Trapp. This shows that the opinions at the top were not the same as among the members of the organisation and the election committee couldn?t rule over them.In this essay I try to understand what kind of organisation LRF is and what made this case special.
Integrationens paradoxer : En intervjustudie av integrationen i praktiken
The purpose of this study is to examine the relations of power within the discourse of integration and my focus will be on power relations and structural discrimination. The study origins from four qualitative interviews with employees from the County administrative board as well as from the Employment office.The theoretical framework is based upon Social Constructionism, Postcolonial Theories and with an intersectional perspective. The recent critical research from The Official Report on power, integration and structural discrimination (Utredningen om makt, integration och strukturell diskriminering) is used as well as Foucault's theory of biopower which is discussed within the analysis.The study indicates that although integration often is addressed as a reciprocal process, it is still assumed that They should be integrated by Us. The present government's one-sided focus on employment has proved difficult for the employees to put into practise and when the responsibility of obtaining employment is based upon the individual alone, she/he becomes responsible for her/his own integration..
