SVT is Sweden?s largest TV-network and broadcasts more then 22 000 hours of TV each year. SVT is a public service company where the basic idea is to reflect the world from different perspectives and news is very important for providing neutral and versatile information in a variety of areas. An important part of the flow of information is to continuously receive reports from all corners of the world around the clock. This places very high demands on the technology used and it is important that it function and develops to meet current and future growing needs.

This master thesis has been performed at Solvina in Gothenburg for Skellefteå Kraftand Vattenfall Eldistribution. The aim of it is to investigate the consequences of theinstallation of a wind power plant on the mountain Uljabuouda in the vicinity ofArjeplog. Especially the impacts on voltage and transient stability are examined.Furthermore, the amount of extra strain on the voltage regulation equipment and theneeds for increased regulation capabilities are looked into.The wind power plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines assumed to be built on Uljabuouda.- Simulations of different operation cases and analysis of the simulation results.The results from the simulations show that, as far as voltage stability and extraworkload on tap-changers are concerned, the wind power plant does not, in anysignificant manner, worsen the present conditions. The problem of overloading theline between Arvidsjaur and Vargfors is also minor.

Sammanfattning Studiens syfte är att vidga förståelsen kring hur förskolepersonal konstruerar sitt professionella subjekt. Förskolepersonalens föreställningar om och intentioner i verksamheten visar på olika former för makt och motstånd i deras positionering som professionella. De centrala frågeställningarna för studien är: Vilka föreställningar, intentioner och former för makt och motstånd kan skönjas i förskolepersonalens samtal om förskolan och reflektioner kring egen praxis? Vad framträder som betydelsefulla delar i förskolepersonalens konstruktion av det professionella subjektet? Hur, i förhållande till dessa delar, positionerar sig deltagarna som professionella? Deltagarnas gemensamma samtal och enskilda reflektioner kring eget agerande står i fokus i studien. Förutom Foucaults teorier om makt används feministisk poststrukturalism i en strävan efter multipla förståelser av såväl subjektkonstruktionens processer som ställningstaganden och övervägande angående studiens utformning och innehåll. Intervjusamtal med respektive arbetslag och individuella reflektionssamtal utgör studiens empiriska material.

With the rise of the internet especially and information- and communication technology in general, the opportunities for fast and effective communication and sharing of information have proliferated. In relation to the new technologies, the citizens? demands on organizations? communicative efforts have increased. Today?s citizens have high standards regarding transparency, the opportunity to dialogue and have hopes to influence the public sector.

Our Bachelor´s Thesis has been performed in co-operation with Bors Automation & Tool AB.Our task was to develop a servomotor powered tube cutting-machine with initial point fromtoday's hydraulic driven tube cutting machine Bors HYD 23. The purpose with the newconstruction was to achieve a more power-efficient tube cutting machine which could lowerthe power consumption, and also meet the market continued growing demand forenvironmental-conscious production.Bors Automation & Tool gave us relatively free hands in order to enable new thinking ideaswithout following their traditional constructional solutions.Our solution resulted in a construction based on a power source existing of a servomotordrivenrollerscrew, witch provides a more rational use of energy compared with the currentmethod.Bors Automation & Tool AB has decided to fabricate a prototype of Bors E 23 during theautumn of 2007, which they are planning to revile at the Tube 2008 exhibition in Düsseldorf,Germany.NOTE:Due to an agreement signed by the authors in the beginning of this project, no appendix is published at this time.If you want to wiew these documents, please contact the authors..

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

The aim of this investigation work " What was it called...Equality...? is to study a clinics current gender equailty plan from a gender approach and by a field survey see if, and in that case, how it can be improved. A connection between existing gender norms and gender power strukctures is applied in the results of this survey in order to illustrate their significance from an individual as well as a structural perspektive.The survey has been carried through by a field survey as well as a discourse analysis as method. Yvonne Hirdmans gender power system is on of the main theoretical points of departure.The results that I have achieved in this essay is that gender can be looked at in different ways within the labour market where women have the main responsibility over the family and are considered more nursing then men. Men on the other hand are thinking of their carriers and have higher salary requirements.

Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.

This essay discusses how popular literature in general and Stephanie Meyer?s Twilight-series in particular can be useful in the classroom, despite, or rather, thanks to, its inherent problems concerning gender roles, relationships and the power systems within them. The essay takes a reader and teacher centered approach in describing both the problems of Twilight and the ways these problems can be worked with in the context of the school subject Swedish in upper secondary school. It makes an inventory of Twilight?s problematic aspects, and attempts to use them in conjunction with the governing documents of the Swedish school system.

Purpose/Aim: To find power structures within the blog network.Material/Method: Using keywords to find all available blog posts about the National Defence Radio Establishment from the blog search engine Twingly, and thereafter using the same blog search engine to find inlinks from other blogs, to those posts. The data is set into the context of the small-world networks models of Duncan J. Watts and rich-club models of Sergi Valverde och Ricard V. Sole.Main results: 5183 unique blogs have written about the subject in 22779 blog posts to which 28128 inlinks from other blogposts are made. Just over one fifth of the blogs are linkted to each other in one big network, where the remaining blogs stand without any ingoing or outgoing links.

On the first of October 2012 the media reported that the women in the Ikea cataloguehad been airbrushed in the Saudi edition. Initially the blame was put on either theSaudi government the Islamic culture or the Saudi franchise. In the end it wasrevealed that the Swedish company Inter Ikea Systems had the full responsibility forIkeas actions and therefore was the culprit behind the airbrushing. On whoseinitiative or why the airbrushing was done the media never found out. These areanswers only Ikea has, although they remain unresponsive to these questionsthroughout the news portrayal.This study methodology uses a qualitative content analysis as framework to furtherinvestigate the news media with support of theoretical perspectives such as mediatheory, power relations and cultural differences.

Central African Republic has partly been portrayed in the media as a forgotten crisis, but also as something that is completely natural for how it is in Africa. The society has perceptions about Africa, which has been reproduced and reconstructed in the selected articles. The discourses in particular have appeared in articles are discourses about: us and them, the confidence in experts, social representations especially (emotional roots), ideological inequities and power relations between different parties..

This essay shows how the concept of virtue can deepen our understanding considering processes of empowerment. A virtue is understood as a trait of character, manifested in habitual action, that it is good for person a to have. Virtues are interpreted as socially constructed. Empowerment is presented as a process toward self-confidence and self-determination where recourses and freedom propels the development toward power for the individual, the household and the community. Why does the concept of virtue deepen our understanding? It is argued that our theoretical perceptive of empowerment needs to better encompass values, norms and practise.

This is a study with a qualitative approach and a social psychological perspective. Our purpose is to describe and analyze authority officials descriptions of individuals with a social disability and their perception of how the interaction in the encounter with its implementation.

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..
