Tidssynkroniserade mätningar i vattenkraftstationer

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 Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

Väljer man rätt? : en uppföljning av Svensk baskets regionsuttagningar

AimThe purpose with this study is to evaluate the selectationprocess and what happened with Swedish basketball players born 1986-89, that were selected to participate in Miki Herkel Cup (MHC), which is a camp for the 60 most talented players in Sweden.Metod  Together with the Swedish basketball federation, we decided to survey those who attended MHC as well as the players playing in the senior national team 2009.  The data collection has been made through a survey, with multiple choice questions in order to get as good as possible view of what factors that had influenced their development as basketball players. The survey was sent out to all players born 1986-89 that attended MHC and the senior national team of 2009. We used an electronic survey tool called questback which is an internetsurvey and sent out the survey to 320 players. To collect information we´ve searched within literature and databases.Result  18 % of the players answered the survey, which decreases the research validity.

Nationell identitet i konsten : Peter Johansson dekonstruerar mytbilden om svenskhet

The purpose of this examination is to identify how notions of Swedishness is created artistically, and from where these notions come. My method is to make a study on exhibition catalogues on the theme Swedishness/Nordism, with focus on the contemporary Swedish artist Peter Johansson. With a retrospect of his childhood in Dalecarlia, he investigates a Swedish iconography with it?s roots in national romanticism, which for more than one hundred years has been preserved and exploited of the tourist industry to market Sweden. It?s this monotonous iconography that Johansson deconstructs to make it appear like something else ? namely an iconography based on ethnic purity, which pushes away the foreign and protects the own.

Acceptansgränsen för solceller i lågspänningsnät : Kan den ökas?

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.

STRESS COPING OCH COPINGEFFEKTIVITET BLAND SVENSKA POJKLANDSSLAGSSPELARE INOM FOTBOLL

The aim of this study was to study how Swedish youth national football players handle stressful events in sports. A longitudinal questionnaire diary was constructed from a revised version of Nicholls and Polmans (2007) design with the intention of recording in-sport and psychosocial stress, choice of coping strategy and coping effectiveness. The participants were 59 Swedish youth national football players born 1992 observed during a four day national training camp held by the Swedish Football Association. Data were drawn from a quantifying analyzing method. The main result showed that the most common stressors reported were, physical injury or pain, experiencing teammates or opponents to perform better and feeling generally insecure during training camp.

Barn i fokus: En komparativ studie av arbetet med barnverksamhet på folkbibliotek i Sverige och Italien.

The purpose for this Master?s thesis is to describe the similarities and the differences of the work at the public libraries? children?s sections, between Sweden and Italy. In order to do that we examine the cultural political presumptions that Swedish and Italian libraries have, such as policies concerning public libraries and children, on a national as well as an international level. We also look at existing attitudes regarding the work at the public libraries? children?s sections, among authors of research literature in our subject.

"Ölhallen" - en hjälp i nyhetsarbetet : En kvalitativ studie av några nyhetsjournalister och sociala medier

This is a qualitative study of how some journalists on the Swedish national media are using social media in news work. The study, carried out by using interviews, also covers how these journalists' work is influenced by social media. For the journalists in the study social media has become a tool to do research, get news ideas and find interviewees. At the same time social media affects the work of the journalists, as the social media increases the speed of news and flow of information. Even though they involve some challenges, social media facilitates news work and the journalists in this study have a positive attitude towards the phenomenon.Keywords: Social media, news journalism, the national media..

Det komplexa mötet mellan intentioner och upplevelser : Intervjustudie om hur några grundskollärare uppfattar en ny läroplan

This essay takes its starting point in the making of a new national general school curriculum for the Swedish elementary school. The purpose of this essay is to estimate what the policy makers intended with the new policy documents and relate that to how a few teachers perceive these changes. In order to get an understanding of how the teachers view these changes I have done qualitative interviews with four teachers which all work in the Swedish elementary school.Theories on "implementation" and "street-level bureaucracy" are used to analyse my empirical material. My results tell that there is a difference how teachers relate to the new curruculum and the policy makers' intentions with it. That can be explained by the fact that teachers' work is complex and as to they work in a complex organization..

På spaning efter Cinelitteracitet : En granskning av filmämnet i de nyutgivna läroböckerna för Svenska Gy11

This thesis will explore how the medium of film is treated in the recently published Swedish textbooks and how these textbooks take into account the four different aspects of Cineliteracy.Cineliteracy is a theory which advocates the necessity of students' increased cinematic knowledge by presenting the four skill areas that should be included when it comes to teaching film in school. The theory implies students´ analytical skills, contextual knowledge and knowledge of the film canon as well as the development of students' skills to produce films. Cineliteracy theory finds support both within Swedish National Agency for Education and in recent Swedish research.This study includes investigation of eight new textbooks, adapted to the criteria for the new Swedish curriculum 2011. The analysis will be limited to textbooks for the course Swedish 1, since it is mandatory regardless of the orientation of the student?s education..

Vilka stora tänder du har! : En kvantitativ analys av fyra svenska tidningars rapportering om vargar under 2011 och 2012.

This BA Thesis in Journalism is a quantitative analysis of the coverage of wolves in Swedish printed media. Namely four daily newspapers, two national and two local. The two national newspapers are Aftonbladet which is a leading tabloid newspaper with national coverage and Svenska Dagbladet which is one of the two major newspapers with national coverage, as well as coverage of the greater Stockholm region. The two local newspapers are Falu Kuriren, which is located in Falun and mainly cover the province of Dalarna and Nya Wermlands-tidningen which is located in Karlstad and mainly cover the province of Värmland. These are provinces which have a large wolf population.As the work progressed we found that the newspapers have handled the coverage of the wolf in, what we believe, a good way.

Debatten om övergången från SAB till DDC ? Hur ser den ut?

In 2008 the National Library of Sweden decided to give upClassification system for Swedish libraries and start using DDC(Dewey Decimal Classification) from January 1 2011. Thisdecision has influenced the whole Swedish library system and longbefore the National Library of Sweden took this decision thequestion had been thoroughly discussed and debated in Librariancircles.The aim of this thesis is to find out which arguments have beenintroduced in the debate, if the discussion has changed from beforethe decision to go over to DDC was taken to after wards, and if sohow it has changed. My thesis will discuss the following threequestions:? Which arguments were brought forward in the debate,both for and against a transition?? How has the debate about the Swedish libraries?transition from Classification system for Swedishlibraries to DDC changed from before the decision ofthe Royal Library was taken to after?? What conclusions can you draw from the debatewhich has been led about the transition to DDC?The empirical material consists of six articles dealing with thetransition to DDC and in the analysis of this material I have used atext analyses, analysis of. The analysis shows that more or less thesame arguments for and against have been used in practically allthe articles, and the debate has not changed very much.
