Nya metoder för vibrationsmätning på vindkraftverk

This project has revolved around finding better ways of overseeing vibrations of the gearbox at a wind power station. The gearbox has been a huge problem at the stations located at Gässlingen and the sooner the warning of an incoming breakdown is at hand the more money you can save from preparations. The work has been carried out together with Askalon AB in cooperation with consults from ÅF. Askalon is a company with a department focused on overseeing vibrations and it is in collaboration with that department the work has been carried out. During this work, new positions for the sensors and new methods of gathering and analyzing data have been worked out. This was then implemented at a wind power station to be tried out on site.

Ett Imperium På Nedgång?: En studie av USA: s Imperium

This is a thesis about the American empire. I also focus my work to see if this American empire is declining. The two main questions I ask and want to answer in this thesis are: is America an empire and is it in decline?I first conclude that America has been an empire ever since the end of the Second World War. The sheer military and economic power of the American empire matches and exceeds the ones before them.

Tilläggsisolering - lönsamt enligt en livscykelkostnadsmodell?

It is found that the properties of the record years of 1965-1975 is leaking a lot of energy andthese properties are facing a major energy efficiency. From the energy aspect, the facade isafflicted with poor thermal insulation which is a big problem. To address this problem addinginsulation is a good alternative to reduce overall energy consumption of a building. Thewindows on these buildings are also a problem from the energy point of view. Therefore,there are many reasons considered for energy upgrading.

Energiåtervinning från gjuteriprocess till fastighet, undersökning för ökat utnyttjande av spillvärme

This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.

Ett kompatibelt control package? - en fallstudie av Metso Power AB

Bakgrund: Under senare år har många företag valt mer processorienterad inriktning påverksamheten, framförallt i syfte för att förbättra kundvärdet. Många företag har enmer hierarkisk struktur i utgångsläget, vilket innebär att vertikal och horisontellstruktur kombineras. Ett vanligt misstag är då att nya processorienterade styrmedelinförs, utan att existerande vertikalt orienterade styrmedel tas bort. Detta leder tillatt företagets styrmedel sänder ut motstridiga styrsignaler. För att öka företagetsmöjlighet att uppnå uppsatta mål, så krävs det att dess styrmedel är kompatibla.I sämre tider är det vanligt att företag formulerar mål med Net Working Capital somgrund.

"I go to Elland Road sometimes. Would you bomb me?" : en genealogisk närläsning av villkoren för överlevnad och subjektivitet i Sarah Kanes Blasted

Sarah Kane?s first play Blasted (1995) has often been read in a normative and biographical way by critics, authors and previous researchers. This essay makes a supplementary close reading of Blasted from gender and genealogical perspectives and utilizes theoretical works by Judith Butler, Luce Irigaray and Michel Foucault. My study makes clear that the characters different positions in language and talk create and maintain a power imbalance between them. Efforts to change and develop one?s individual position in language and talk are being made throughout the play since it is the only way to bring about a change in the social power structure.

Selektivitet mellan hög- och lågspänningssäkringar ? I anläggningar med transformatorer ? 500 kVA

Göteborg Energi AB är ett bolag med höga ambitioner att säkerställa ett stabilt distributionsnät för sina kunder. Med ett säkerställande följer åtgärder i form av beräkningar för komponenter som transformatorer av olika märkeffekt, hög- och lågspänningssäkringar och andra kritiska skyddsanordningar som t.ex. reläskydd. Vid ett flertal tillfällen under de senaste åren har det uppmärksammats en problematik där ett fel i lågspänningsnätet har löst ut anslutande transformator. Felet har grundat sig en svag selektivitet mellan transformatorsäkring och lågspänningssäkring.

REDOGÖRELSE FÖR SPRICKARMERING FÖR KONSEKVENT DRAGNA BETONGPLATTOR PÅ MARK : Analys av skillnader mellan BBK 04 och Eurokod 2 med tillämpning av svenskt och danskt nationellt annex

In this diploma work the approach of determining the required amount of reinforcement in slabs exposed to pure tension is processed, on behalf of Ramböll Uppsala. It is a well-known problem in the industry that there are uncertainties in the determining of the amount of crack reinforcement, especially for structures exposed to pure tension. Cracking caused during the time of dehydration in concrete slabs is the most common defect according to statistics made by CBI[1], which provides numbers as high as 35 % of all the defects caused on slabs are generated by cracks. Comparisons between Sweden's former national standard BBK 04, Building Regulations for concrete structures due to restrained forces of shrinkage, and the current European standard Eurocode 2 are carried out through theoretical studies and concludes with several examples of calculations. Rigorous calculations of both standards, BBK 04 and Eurocode 2 with application of the national annex in Sweden and Denmark are performed.

Mentala gränser & social hierarki i det folkvandringstida dräktmaterialet

The purpose of this essay is to inquire whether there are any resemblance or differences in the Migrationperiod textiles between the three places that I have chosen, Högom in Sweden, Evebø and Snartemo in Norway. Another purpose is to investigate if this magnificencedressmaterial indicate some kind of mental borders, social differences or hierarchy not only towards other powerful chieftains in other areas but also inside there own society and groups, a dresscode. In other words both individually locally as regionally and internationally. If there are resemblance's between the dressmaterial, gravefinds and the graves context could that be a sign of the same sphere of power, alliances, trading, intentional import, domesticproduction, culturedistribution? My aim in this essay is to try to show that the textile ought to have a higher significance place among archaeological material.

MIGRATIONSSTYRNING I EUROPA: MAKT, KV?VNING OCH KONTROLL En kritisk maktanalys av migrationsstyrning i Europa genom utrikes f?dda kvinnors arbetsmarknadsintegration i Sverige

In today?s Europe, migration has become a security issue rather than a humanitarian issue. Previous research highlights how migrants have become prisoners of bureaucracy in Europe by their mobility being hindered. The present study critically analyses the migration governance in Europe by highlighting labour market integration in Sweden. The study highlights migrants with a specific focus on foreign-born women. The research questions chosen to examine this phenomenon is: How does migration governance in Europe affect member states' policies for labour market integration, with a particular focus on Sweden? How do foreign-born women in Sweden experience labour market integration processes within the framework of the governance mechanisms that exist in Europe? Foucault?s theory of power and the theoretical concept of choking composes a theoretical framework which is used to analyse focus group data and text analysis data.

Vindkraft: en undersökning av fem europeiska länders vindkraftutveckling och faktorer som kan påverka den

En del länder väljer att investera och utveckla vindkraftmarknaden mycket, medan en del länder väljer att inte göra det. I Europa startade vindkraftutvecklingen under 1970-talet. Efter en trög start är den europeiska vindkraftutvecklingen nu marknadsledande och fortsätter att expandera i hög takt. Tyskland har den högsta installerade kapaciteten av vindkraft i världen, och Danmark har den högsta installerade kapaciteten per capita. Dessa länder, samt Spanien, Sverige och Storbritannien har alla satt nationella mål för utvecklingen av vindkraften.

Vem är du? : En studie om etnicitet och positionering på den svenska arbetsmarknaden.

Research shows that non-european academics are discriminated in the labor market. The purpose of this study is to examine non- European academics narratives about their Job search process. By applying an intersectional approach, this study aims to demonstrate how the interplay of different aspects such as gender, class and etnicity shape the interviewees experience in swedish labour market. A postcolonial perspective is applied in order to contribute to deeper understanding of the discriminating structures that the interviewees deal with.The analysis shows that colonial conceptions are embedded in the validation system and institutions such as employment service. This mechanism affects the interviewees negatively in their Job search process.

Optimering av sotningsfrekvens i biobränsleeldad CFB-panna : panna 5, Mälarenergi AB, Västerås

During the past 30 years the fuels for energy production in heating and power plants have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden have increased with 60% since the 1970's. Different fuels affects combustion and the release of various substances and particles into the flue gas. This is caused by the diverse components and chemical structures of fossil fuels and bio fuels. When the flue gas leave the combustion chamber and enters the path to the chimney particles in the gas are being transported out of the combustion chamber.
