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.

Bloggar och dagordningsteorin : En undersökning av bloggreferenser i fyra svenska tidningar under förvalsperioden 2006 och 2010

For the last ten years Internet has become more popular and is now used by most Swedes every day.  Internet has made it possible for many people to access a great deal of information about news all day long. Internet has also made it possible for people to create their own news and comment on happenings as they are taking place. One way to do this is to start your own blog, which is a kind of diary where you can publish your own thoughts about politics and news.In Sweden the media is often referred to as the third governmental power since the media is examining the government and people in power positions and bringing the people as consumers of news closer to the government. There is a theory called agenda setting that says that the media is an actor that shapes the political issues discussed by the people and politicians.In this essay I have used the agenda setting theory and linked it together with the Medias references to blogs in their news. This I have done to see if the media might be influenced by blogs.

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.

Hur påverkar en ökad andel solceller Umeå Energis elnät? : ? En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

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..

Analys av PWM-mönster i Matlab

One of ABB Power Systems´s business areas is HVDC (High Voltage Direct Current) technology. HVDC is used for transmissions for both short and long distances. One of Power Systems?s products is called HVDC Light. HVDC Light is a relatively new technology for power transmission, but have before only been used for motor drives applications.

Ålder - en ny och komplex diskrimineringsgrund

Age is one of two new discriminatory grounds in Swedish law. EU took official position against age discrimination by means of Council Directive 2000/78/EC of 27 November 2000 establishing a general framework for equal treatment in employment and occupation. From January the 1st 2009 it is, by Diskrimineringslag (2008:567), illegal in Sweden to discriminate anyone based on age. The law covers all age groups and is applicable to various fields in society. Age differ from other discriminatory grounds since everyone has an age.

Statuskontroll av Paradisskolans elektriska belastning

In this thesis is studied the electrical load of Paradisskolan with respect to power quality and energy consumption. The school's owner Trollhättans Tomt AB is also interested to know if they can reduce their costs by changing to smaller meter fuses. A recurring ground fault that?s been recorded from powerpanel A1A has been investigated. 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.

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.

Skriftspråksskillnader? : En jämförande studie av flickor och pojkars skriftspråk på gymnasienivå

Our society has faced monumental changes and therefore our working life has changed as well. We are now in the twentieth first century and still our labor market is gender-segregated. Today networking is an important part of working life and one cannot emphasize enough the importance of having good connections in your network. Networking is now seen as an important tool when it comes to your career. In the past networking has been the men?s arena and it has almost been seen as a male institution.

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..

Könskvotering i bolagsstyrelser : Ett instrument för att främja en jämställd arbetsmarknad?

The European Union has been working to promote equality between women and men for a long time. Despite this, Sweden still have a gender segregated labor market where men generally has the leading positions. According to European law the member states shall promote gender equality and to take all appropriate measures. Statutory gender quotas for company boards is one such measure that some of the European member states have implemented in national law. The Swedish law has no provisions governing gender quotas and therefore the purpose of this study is to explain how gender quotas for company boards relate to current law, both of European law and national legislation.

Ersättning av Ringhals 3 med ett biobränslekraftverk

This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.

Hundratusentals livsöden på några blad : En komparativ studie mellan ett museums förmedlande av utvandringen och dagens läroböcker

The aim of this bachelor?s thesis is to analyze if there are differences in the way of explainingthe causes of The Great Emigration from Sweden to America in the late 1800s/beginningof the 1900s. Due to the researcher?s education the thesis has a didactic, and comparativeperspective between how history textbooks aimed for Middle School and High School andhow the exhibition Drömmen om Amerika (= The Dream of America), in Vaxjo, Sweden,explains this phenomena. A special analysis scheme is applied to the sources in a way to makeit clear to the reader how informative they are and how much effort they put in the explaining.The outcome of the analysis shows that the exhibition gives the visitor a wider, deeper,and more informative depiction of The Great Emigration, compared to the textbooks? moresummarized extracts.
