Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

The aim of this Masters thesis is to examine librarians attitudes and values when it comes to the question if a new media, video games, should be introduced at the library or not. Video games are here seen as media primarily for youths. In our study we also wanted to study the discussions of quality and purchase, when computer games were introduced at the library. In order to answer our questions we conducted nine interviews with librarians working with children and youths, in eight libraries. By analysing their statements, using Maj Klassons theory where she defines the librarians role in three different strategies, we could demonstrate how the librarians reason when it comes to video and computer games, youths, quality and purchase.

Den här rapporten undersöker om och i så fall hur webbplatser kan användas som ett återkommande inslag i matematikundervisning. Bland annat Skolverkets utvärdering av grundskolan 2003 visade att matematiklektioner av många elever upplevs som långtråkiga och enformiga. Med rätt utformade applikationer för dator och Internet kan kanske ett medium för ett annorlunda och för eleverna mer engagerande sätt att lära matematik erbjudas. Inom det här projektet konstruerades en webbplats med uppgifter som nästan uteslutande utformats som små spel och sedan delat sin i nivåer efter svårighetsgrad. För att klara en nivå och på så sätt ta sig vidare till nästa behöver en elev först klara alla uppgifter på den aktuella nivån.

The possibility and the right to be able to communicate with municipalities or other state companies and politicians are natural for the Swedish citizens. However, they may be unaware that this communication process is called citizen dialogue.Today there are so many ways to communicate; one-way communication is not possible in the same way as before. It is above all social media such as Facebook, which has opened the gates one could only dream of.  Via a medium such as Facebook creates a strong citizen dialogue in which the municipality and citizens communicate openly and ask questions and give response.The purpose of this study is to find out how Karlstad?s municipality uses, and maintains, citizen dialogue on Facebook. What are the guidelines and how do the municipality use these? In this paper a qualitative expert interview and a qualitative content analysis has been used to answer the purpose of the essay.

AbstractThe purpose of this study is to examine how children interact with each other and what social positions they assume when using the learning pad. The social positions reffered to is the Owner, the Participant and the Spectator, defined by Ljung Djärf (2004). According to Ljung Djärf (2004), the Owner is defined as the one in control of the mouse and keyboard. The Owner is expected to be in charge of what is happening on the screen. The Participant is typically found on a chair near the computer.

This study aims to investigate and describe the direction of the ideological development of the Swedish gymnastics association Gymniska Förbundet. Between 1928 and 1932, this organization transformed from a purely gymnastic and cultural association into an influential platform for the production of Swedish nationalist ideology. Based on theories of National Socialism?s formation within modern society, the analysis focus on the conditions regulating Gymniska Förbundets relation to modernity. Thus the study examines the association?s ideas in relationship to the concept of modernity.

The purpose of this Masters Thesis is to explore the process of selection that librarians face when selecting and acquiring cultural magazines to public libraries. The methods used are qualitative interviews and literary studies. A brief review is given of acquisition policies at public libraries and of cultural magazines and the important role they play in public libraries. Five interviews have been made at five public libraries to find out what factors affect the process of selection when it comes to cultural magazines. Two theories are used as a basis for the analysis of the result of the interviews and literary studies.

The discussion about high culture and popular culture in our society has been going on for decades. In few places is it as loud as within culture journalism and the critics? society, where the question of what is good taste and what is dumb entertainment constantly gets brought to the surface. Film is a particularly vulnerable area, since it is such a universally appealing and rather young medium. In America and England several studies have been performed of the reviewing society and reveiwers? use of high and low art-discourse in their writing.

This thesis aims to investigate what requirements companies have in order to achieve a successful legislative compliance control. The implementation of an environmental management system can help the company to structure their business and succeed with their environmental legislative compliance.Both small and medium sized businesses perceive that it is difficult and time consuming because the legislation can be difficult to interpret if you do not have the required knowledge. There are many companies that hire help in the form of consultants who audit their compliance, but this leads to a risk that the company will be exposed when the knowledge does not remain in the company if the consultant would cancel the cooperation. There are not so many tools today for businesses to obtain good legal compliance. The methods used are usually checklists included in the control program, and it costs a lot of resources to do everything needed.This study strives to deliver the expressed needs of the businesses.

The aim of this study is to examine possibilities and barriers for an introduction of electric vehicles in Sweden. The study has an interdisciplinary approach and thoroughly examines the essential topics which influence the future of the electric vehicle. The study reaches from answering the question on why electric vehicles lost the game to petrol cars in the early 20th century, to sketch how the difference in total cost of ownership will be between electric vehicles and petrol cars for the coming 20 years. Apart from these subjects the main topics of the study are today?s and tomorrow?s situation regarding technology, charging, fuel, market and economic incentives from an electric vehicle perspective.

The Swedish healthcare system is characterized by lack of resources and extensive hospital queues. In order to counter these difficulties the Lund University Hospital have introduced Lean Healthcare to the hospital organization. The purpose of this scientific paper is to study the relationship between the implementation of Lean Healthcare and the experienced motivation among the staff. This essay thereby intends to impart knowledge, which could be used on future implementations of Lean Healthcare at other hospitals. In order to fulfil the purpose of this essay a case study have been conducted at two wards at the Lund University Hospital in which qualitative research interviews have been the method chosen in order to gather data.
