When several production units provide a district heating network, water is pumped from different directions. When the flows from the plants finally meet in the network, the water can be completely still. These places are called zero flow zones. In district heating networks with several plants, which also have different supply temperatures, large and frequent temperature fluctuations can occur when the zero flow zones move. This may cause wear on the pipes, a phenomenon called low cycle fatigue.For this reason it is important to examine where and when zero flow zones that cause temperature changes occur.

Abstract The purpose of this essay is to compare the integration policy between Socialdemokraterna, Moderaterna and Sverigedemokraterna with focus on labor-market integration, housing segregation and language knowledge. The international immigration has in recent years increased significantly and this has also enriched the receiving countries and still the numbers of extreme right parties have increased. In Sweden a racist populist party, Sverigedemokraterna, are only a few steps away from entering the parliament. The question in focus is: What differences or similarities are there between the integration politics between Moderaterna, Socialdemokraterna and Sverigedemokraterna with focus on the areas housing, work and language?  By applying the theoretical framework to the data, I have been able to present answers and build up an analysis. The study concludes that there are more similarities than differences in the integration policy between Moderaterna and Socialdemokraterna.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

I dagens samhälle har många kundföretag problem med datalagringen vilket beror på att behovet av att lagra data började öka kraftigt under 2000-talet och har fortsatt öka sedan dess. När kundföretagen började använda sig av virtualisering så expanderade även datastorleken. I samband med att datastorleken växte ville företagen att data inte skulle lagras lokalt utan att den skulle vara lagrad på en central plats som en serverhall och vara överskådlig.Studien utfördes på tre sätt, först undersöktes vilka datalagringslösningar som fanns och det skedde genom litteraturstudier. Därefter kontaktades företag som använde olika lösningar för datalagring. Nästa steg var att kontakta de leverantörer som kundföretag använde sig av och som levererade lösningarna.Under arbetets gång upptäcktes olika lösningar på problematiken med ett ökat datalagringsbehov.

Discussions about the democratic deficit of the European Union have gotten more intense and the criticism usually points towards a great gap between the citizens and the EU politics. In this study the political communication policy is being put under the scope to investigate to what extent the policy is designed to counter the democratic deficit, supported by the theory of deliberative democracy. The analysis examines three aspects of the deficit ? decentralization, participation and the distribution of information ? and makes research into the communicative measures that have been implemented. The importance for EU to make deliberation possible is stressed throughout the essay and in the conclusion I argue that improvements still need to be made.  .

Public opinion has increasingly become a political force in the European integration process. At present, it appears that the people?s attitude towards the European integration is relatively skeptical. How can we expect that the attitude towards European integration will evolve in the future? This paper tests the extent to which diffusion theory can serve as a model to explain the development of attitudes to European integration policy in Sweden from 1999 until 2009.

AbstractTurkey has emerged as a major actor in the Middle East over the last decade, since the ruling party AKP came to power in 2002. Turkey is now playing a mediation role in regional conflicts and has been speaking out loudly on sensitive issues such as the Iranian nuclear program and the Palestinian- Israeli conflict. Furthermore, Turkey has established close ties with the Arab world which has suffered the relationship with its long-time ally Israel. This new presence in Middle East has been criticized by Turkey's allies in west. Critics argue that the country is about to abandon its former western relationship and strengthen their ties with the Arab world instead.This thesis has two main purposes.

This is a two year master's thesis in the field of museum and cultural heritage studies. The purpose of the thesis is to examine different opinions among museum employees about the role of museums. The thesis also aims to find out to what extent and in what way these opinions are influenced by the museum's own policy documents, the national cultural policy and the academic field of museum studies. I have conducted qualitative research interviews with six employees from three different cultural history museums. The theoretical framework of the thesis is based on Laruajane Smith's term authorized heritage discourse.

The EU has for a long time had a special relationship with its former colonies in Africa Caribbean and the Pacific, called the ACP?countries. This relationship is about to change radically with the new partnership agreement signed in June 2000 in Cotonou. This essay aims to study the EU ?ACP Partnership Agreement from the perspectives of two different theories: The liberalist, free-trade policy theory and the nationalist/regionalist, protectionist theory.

Open access (OA) is a publishing model aimed at increasingthe access to academic research results. The object of thisstudy was to contrast nine colleges and four fundingorganizations in Scandinavia with mandatory OA-policies,and to study how they put OA into practice.Inspired by the Open Access Spectrum (OAS), a tool used toappreciate the OA of academic journals, the aim was tograde the policy documents of the colleges using the OASmodel.The study also compares how the colleges implementtheir OA-policies as well as how, and if, the demands fromthe funding organizations are reflected in the policies of thecolleges.The findings show that the OAS is not a tool designed forgreen OA and that all the information needed for the scale tofunction was not found in the policy documents we studied.A selection of the colleges has some demands in theirpolicies, although most of them allow exceptions to be madefrom the mandatory policy. This is shown to be mainly aquestion of academic freedom, and copyright, or rather thanthe degree to which the scientist and the publisher can cometo an agreement on allowing the information to be accessiblethrough OA.The study proposes that the way to change this may be toincrease the demands on OA in the policies, and that the bestsolution might be in stipulations within the employmentcontracts between the individual colleges and scientist..

The aim of this essay is to investigate the implementation of The Social Orientation inSweden. The Social Orientation is a part of the new, one year old, establishment law and isaimed at all newly arrived refugees and immigrants. The aim of the law is to help establish allnew arrivals into the Swedish society by providing knowledge about life in Sweden. Theeducational program is at least sixty hours long and covers: the public authorities in Sweden,laws and regulations, work and education, healthcare, children and family issues in a person?smother tongue.In order to achieve my aim I have chosen two questions: How has the law been implementedin Swedens three counties: Stockholm, Sörmland and Uppsala? What conditions are there fora successful implementation?In order to answer these questions I have used the traditional, ?street-level bureaucrats? andnetwork perspectives and issues for my study of implementation.

In the post Cold-War era, world politics was transforming itself through its emerging complex issues such as terrorism and influential and interdependent actors such as the European Union. In this new era, the European Union was developing its Common Foreign and Security Policy pillar both to present a coherent and unified EU policy and to prove its political potent in order to become an influential actor on world politics. On the other side, security environment was also transforming its content through emerging actors and issues. As one of the most prominent actors of the world politics, the EU was influenced by the transformation of security environment, whose economic ?soft power? proved necessary but insufficient for being a global power in this emerging security environment.

Because social media is personal and reaches users directly, it has become an important means of communication for companies trying to reach out to their audience (Nygren & Wadbring, 2013). Especially the possibility of interactivity has been discussed as social media's big advantage. But how much two-way communication is actually possible on social media? This is a quantitative study that focuses on how Swedish Facebook users in the ages of 16-25 interact with companies on the social network. The aim was to contribute with increased information and knowledge about how the users mentioned above interact with the companies as well as how the users perceive the companies communication and presence on Facebook.

Society and technology develop together in interaction processes. Because of the development of information technology, the Industrial society has been left behind in favor of a society where information is the key production factor, i.e. the Information society. In the Information society, social functions and processes are organized in networks. These networks integrate geographically separate markets to parts of a complex global economic system.
