Grid codes are becoming more demanding on power generating units due to the factthat the complexity of the power grid is increasing. The penetration of wind powerhas grown over the last years and it is clear that wind farms need to be addressedwith the same type of grid codes as conventional generation units. There is howeveran undeniable difference between the technology in conventional synchronousgeneration units, and the asynchronous generation units in wind farms.This thesis has reviewed the current grid code in Sweden and compared it to the newcode proposed by ENTSO-E, ?the Requirements for Generators?, in the aspect ofwind farms with an installed power of 30 MW or more. The comparison has beencomplemented by an analysis of how wind farms of two different technologies(Doubly fed induction generators and full power converters) can meet therequirements and technical proposals have been given on how to be able to meetcompliance with the new grid codes.The Requirements for Generators contains many non-exhaustive and optionalrequirements, because of this it has been difficult to, at this stage, exactly point outthe technical impact on the grid connection of future wind farms in Sweden.

The media plays a key role in constructing identities and categories, as its messages influence the way we understand the world. In the debate on integration issues, categories such as ?Swede? and ?immigrant? are often treated as obvious and unproblematic. ?Swedish?, being the norm, is seldom defined   and   frequently appears   with   subtlety.   This   paper   set   out   to   study   what   characterizes Swedishness in newspaper articles on integration issues, and how it is represented in relations to immigrants.

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.

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.

AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards  between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes.  The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.

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.

The aim of this master thesis is to create an understanding of what it can be like to grow older as a homosexual man in Sweden today. The study has an intersectional and queer theoretical approach and is based on eight in depth interviews with men who are aged between 68 and 82 years old. In the analysis I deal with the problem of how sexuality can be inter- preted with the experience of aging. Central to the analysis is the criticism of norms connected to age, sexuality, social- and family life and gay culture.The results show that the norm-breaking sexual orientation of the men affects their life path in terms of how to organize social life, where friends often replace the traditional family. New ways of forming relationships and living their lives imply other obligations rather than the traditional for significant others, which was shown to influence the expectations and outcome of old age in terms of care and support.

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 project has resulted in an website at www.tinadunker.se, where you also can download the project in it´s written form to get a deeper view of the project. This project aims to explore fear of violence in public places. Fear of violence reminds us that there is a problem in our urban environment that leads to spatial consequences in using public space. Many groups in our society experience fear in their everyday life but this project has focus on women?s fear.

This thesis is a discourse theory analysis of two feminist anthologies - Det heter feminism! and F- ordet.  By analyzing these texts through the three categories feminism & feminists, gender equality & equality and sex/gender & sexuality I have raised questions about the feminist debate in Sweden in the 21st century.The discourse theory?s ideas of descriptions of reality and fixation of meaning lies as a foundation for this thesis. The concepts of social constructionism, post structuralism and essentialism/anti essentialism are central for the analysis as well as concepts connected to the three previously mentioned categories.The intention of this thesis is to describe and analyze a fraction of the Swedish feminist debate in the 21st century and discuss its meaning in a societal context. A number of conclusions were reached in the final discussion.

The purpose of this essay is to investigate how social workers experience and understand subjects such as racism, discrimination, and similar attitudes that can exist in institutions of social work. We also want to bring to light how ?race?/ethnicity, gender and class are related to uneven access to Swedish welfare. Our main questions aim to examine how structural and institutional racism forms social workers daily practices and how this in turn affects ?immigrant? women.

The purpose of this study is to investigate how employees in the financial sector perceive the leadership behaviors of middle managers, and if these perceptions differ depending on the manager's gender and if so, in what way. The study is based on a social constructivist perspective and theories of gendered organizational structures. It is based on 15 semi-structured interviews with employees who have either female or male middle managers from different companies in the Swedish financial sector. The results show that gender often acts as a framework for how leadership is evaluated and understood. Female middle managers are frequently associated with relationship-oriented qualities.

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.
