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.

Utvärdering och uppdatering av typkurvor

The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.

Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

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.

Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

Title: Images of Sweden in ItalyNumber of pages: 5252 (589 including enclosures)Author: Oskar GustafssonTutor: Martin NilssonCourse: Political Science C level ? Bachelor?s ThesisPeriod: Spring term 2010University: School of Social SciencesLinnaeus UniversityPurpose/Aim: The purpose of my research study is to, through the use of political science theories on soft power and marketing theories about nation branding and in comparison to previous studies on the image of Sweden in Italy, gains a better understanding of the image of Sweden in Italy, with special focus on national political institutions and young Italians.Method: The method of analysis is a combination of qualitative methods: interviews where information about the image of Sweden amongst national political institutions were gathered and a survey where information was gathered about the image of Sweden amongst young Italians.Main results: On the basis of the results I have gained it can be concluded that a positive and well informed image of Sweden emerges when it comes to cultural and social factors but a more restricted and somewhat negative image come to light when asking national political institutions and young citizens in Italy about their views and knowledge on Swedish domestic and international politics and economics.Keywords: Soft power, Public Diplomacy, Nation Branding, Images of Sweden, Italy..

Våldtäkt, texter och diskursiv ordning : - ett diskursanalytiskt perspektiv på våldtäkt i samtiden

This study's interest area loops around how it is possible to understand texts' leverage over human thinking and acting. Focus lies on understanding which forces that form people?s views around men and women's relationships and relations in the public room. From this perspective our interest is to explore how the phenomenon rape is expressed in texts and how we can understand how rape through these texts are to be shaped in individuals' thoughts awareness and. Finally, it is also relevant to create understanding for how rape as a discoursive practice can have effects on individuals and society.

Elkraftsystem för fälttest av Polygeneration system EXC

I ett modernt samhälle är elektricitet en nyckelkomponent för industrins, individens och samhällets utveckling. Naturkatastrofområden där elektriciteten slagits ut står inför stora prövningar för att kunna få samhällsviktiga funktioner att fungera igen. Med hjälp av den mobila miljövänlig energienhet Emergency Energy Module (EEM) kan elbehovet lindras.Detta examensarbetes mål var att ta fram en elsystemsbeskrivning för den kommande Export container (EXC), samt ta fram ett korrekt elschema för den befintliga EEM.Elsystemsbeskrivningen måste ta hänsyn till EXC:s kravspecifikation samt innehålla Bills of Material (BoM) och elschema. Problematiken ligger bl.a. i att få flera olika energikällor (sol, vind och biomassa förgasare) att fungera tillsammans i ett elsystem där likspänning, växelspänning, trefas och enfas blandas.

Hur kommer barn till tals i domen?

The purpose of this essay was to see how the child's voice was being heard in the verdicts in trials. I looked into court cases where parents wanted custody of their child/children. The focus of my analysis was on how the verdicts were presented and if the child/children were described in the court cases. The method that I used was qualitative documentanalysis. I chose seven court cases to investigate and analyse.I described theories of Foucault's power to get a different perspective on courtroom cases and the children's voice.

Politecast : ett nytt kommunikationsprimitiv för trådlösa sensornätverk

Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.

Implementation av ett digitalt vågfilter på en SIC-struktur

When implementing syncronous filters with global clock nets, a substantial amount of energy is consumed in the clock net. Hence, it is interesting to reduce the size of the clock net, which in turn will reduce the total energy consumption. One way to acheive this, is to create a SIC (Structured Interfacing of Computational elements) since such a structure can be created without a global clock net. Our results show that a fifth order wavedigital filter with a sample rate of at least 10M samples/sec may be achieved.

Religionens roll i konsten och arkitekturen i antika Egypten

The purpose of this Bachelor thesis in religious history, is to examine how religion reflects in the artwork and in the architecture in old and new kingdom in ancient Egypt, also to explore how book of the death reflects in the artwork. By means of using the visual culture theory, I have analyzing the selected pice of art with myths and texts from the ancient religion, to been able to come the the results of this study. It was know that religion had a major part in the artwork of ancient Egypt, especially in the new kingdom. In the old kingdom pharaoh generally was in the centre of the art, but also the gods. In new kingdom they started to illustrate texts and myths from book of the death, and the life after death was of great matter.

Alkohol inom äldreomsorgen : Hur hanteras problematiken?

The purpose of our qualitative study is to investigate how the caretakers, in the elderly care,interpret and manage the issue of alcohol problems in elderly people. We have beenperforming semi-structured interviews on 9 people, on different levels in the elderly care.There were 3 elderly care managers, 1 nurse, 1 assistance administrator and 4 auxiliarynurses, who all, at some level, work with alcohol problems in elderly people. Thoseinterviews were performed singularly, with one exception: we interviewed an elderly caremanager and her 2 auxiliary nurses at the same time. To analyse our empirics, we have usedthe theories of Power and Ageism. Our study shows that the auxiliary nurses, who are theones who must deal with these problems, have great difficulties to perform their work becausethey have no qualified knowledge about alcohol problems.

Fröplacering vid hög såhastighet - Väderstad Rapid jämfört med Amazone Cirrus

In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.
