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.

This study has investigated how urban vegetation can be used in a multifunctional way to support ecosystem services in urban environments. Nacka municipality is in the start-up phase of building what is to become Nacka city. This provides a unique possibility to study and analyse what role the vegetation play in making the city a healthy living environment and how it needs to be adapted in order to be resilient against changing climate conditions and how the effects of those changes can be regulated. The study further investigates how airborne pollution, caused by urbanization processes, can be regulated or reduced by vegetation or species selection. Methods used in this study were a combination of qualitative interviews and literature studies, seeking to answer the questions: Which specific ecosystem functions are needed in the urban environment and which aspects will influence the ecosystems ability to deliver the functions in demand? And which plant species have the right mechanisms needed to deliver those functions? These questions have been studied and analysed in a local based context where the local conditions ands site specific needs of Nacka define criteria for plant selection.

In this thesis the survival and development of a yearly recurring event will be examined. The purpose of this work is to examine how the festival Stockholm Pride has developed and to find out what underlying factors and conditions that lays behind the development. Also being examined is how the event affects Stockholm city?s tourism industry. To be able to fulfill the purpose of the thesis a qualitative research has been used and two persons with allot of knowledge about Stockholm Pride and Stockholm?s tourism industry has been interviewed.

A qualitative interview study how the normative gender images affects on women, their roles and positions in a drug abuse. The purpose of this study aims to shed a light at the consequences that the normative gender scenario inflicts on women with drug abuse and how these prejudices affects these women. Based on interviews with four different women who all lived with a drug abuse we have problematized how the gender system and the normative gender images affected them. We have used gender perspectives and social constructivism theories while analyzing the empirical basis. More specifically we use the theories of Butler about how gender constructs through performative actions and Hirdmans theories of the gender system.

Information technology (IT) have for several decades been used in university education. An increasing number of classrooms today are built around a concept which uses IT in collaboration with the room itself. However, little is known about the experience of university teachers when working in such classrooms. This study examines the views and opinions of teachers at a Swedish university regarding using and interacting with these classrooms. Furthermore, we identify possible underlying factors that influence these views.

The purpose of the study was to determine the attitudes of the teachers of Reggio Emilia inspired preschools concerning the science work with children between the ages of one and three, as well as their opinions on how the physical preschool environment and the choice of materials influence their scientific work. The study was conducted in three departments of two different kindergartens. Although both kindergartens called themselves Reggio Emilia inspired, their working methods and their environments differed largely. None of them were originally built as Reggio Emilia inspired preschools. One of the kindergartens strived to design their indoor environment the same way as the preschools of Reggio Emilia are constructed, there for they were setting up different stations where the children themselves have the opportunity to explore various scientific areas.

The purpose of this master's thesis is to describe and analyse the origin and development of the libraries in the town of Värnamo, between the years 1908 and 1960, when a new modern public library was inaugurated. The method I have used is, to a great extent, examining and analysing source material from the archive of the municipality in Värnamo and the popular movement in Jönköping. As a background to my study I describe the development of the Swedish society, from the end of the nineteenth-, until the middle of the twentieth century. I also describe the local development of Värnamo, during the same period. Furthermore I also give a general description of the progress of the libraries in Sweden during the same time.

The aim of this masters thesis is to examine the picture book canonization process in pre-schools. To succeed in this I have examined what pre-school staff believe to be the criteria of a good picture book. Together with an observation of the pre-schools current collection, other factors which can influence the collection of the picture book are included. This constitutes the foundation for a description of the pre-school picture book canon. To pursue this goal, I have used the methodology of focus group interviews with staff from two pre-schools in a middle-sized town.

Well-functioning bicycle paths are relevant issues in today´s society as a way to increase active transport. Active transport means working for a better global climate, urban environment and public health. What we experience on a bicycle affects the choice of a bicycle path and is a subject where there is much left to explore. This essay examines methods in environmental psychology literature that measure the experiences of landscape. The aim is to find and apply methods to measure the experience of two bicycle paths in the Skåne plains.

This essay analyses the arguments of The Swedish Government Official Report 2008:88 which proposes that the Swedish law (SFS) should shift from promulgation in print to elec-tronic promulgation on a Website. I have studied two aspects of the arguments in the text. On the one hand, the Inquiry?s description of how things might become if their proposal becomes effectuated and, on the other hand, how the present situation is described in the text. The theory I have used is called A Garbage Can Model of Organizational Choice, which pictures organizations as often irrational in dealing with problems, solutions and decision making.

The aim of this paper is to perform a comparative study between the photography?s of Leila Khaled and Shirin Neshat in order to observe if the woman are able to recede from an conventional formation to become the bearer of the veil and not only reduced to that whichneeds to be concealed. From a feministic perspective I have observed how the symbolic of the veil moulds the woman and how the woman in her context moulds the veil.In the description of the news photography of Khaled and the art photography produced by Neshat the mechanisms that lies as a foundation for the modelling of the portraits becomesthe essays primary entrance. Mechanisms that evolve around the creation of the woman as aconcept, a subject shaped for being looked at and the woman?s self-image through others.The textual discourse is visually enhanced through a comparative picture material visually enhanced and explained through photographs by the contemporary artist photographers Cindy Sherman, Catherine Opie, Laurie Simmons, Robert Mapplethorpe and Elin Berge.

The right kind of democracy ? an ideology analysis of school literatures description of the term democracy.Writers: Fredrik Hedlund & Mattias AhlqvistDemocracy is today a word and a concept that in many ways is taken for granted and almost never is reflected on. The concept democracy is also considered as an essential issue in the swedish school system, both regarding the way the education should be managed and also as a part of the students democratic schooling ? all according to the comprehensive document Läroplanen för de frivilliga skolformerna (Lpf94).The main purpose of this paper is to investigate how swedish literature in political and social science talks about and looks upon democracy ? what do the books say it means?The materials we have chosen for this report are the books Zigma and Forum. As metod we are using a textual ideology analysis in which we have created three dimensions ? meaning/associations, criticism of democracy, and demos/citizenship.

The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.
