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.

AimThe aim of this study has been to examine how health enhancement teachers in Montana, USA, view the value of physical activity from a lifelong perspective.In what way does the health enhancement teacher think the importance of physical activity from a lifelong perspective could be presented?What resources are available for teachers to present the value of physical activity from a lifelong perspective?MethodThe issue has been answered through qualitative interviews consisting of six health enhancement teachers, four women and two men, in Montana, USA. One of the teachers worked at an elementary school (for 30 years), three teachers worked at middle schools (20, 10 and 8 years of work experience) and two of the teachers interviewed worked at a high school (30 and 3 years).  ResultsThe majority of teachers feel that a wide variety of activities, adapted to an individual level, and the understanding of a healthy lifestyle are important in order for the teacher to present the value of physical activity from a lifelong perspective.The teachers felt they had sufficient material in order to present the value of physical activity, where the school budget provided the teachers with materials every year. In addition to the budget, all the teachers had 12 hours of professional development every year where they could attend conferences or their own choice of professional development.ConclusionWith the help in forms of professional development offered by the school, conferences, meeting with other teachers, and their own choice of development, the teachers instruction techniques could increase which could help the teachers to find the pupils? interest for different kinds of physical activities.KeywordsPhysical education and health, physical activity, SOC, sense of coherence..

The purpose of this study was to investigate the effect of educational and vocational guidance, refer-only high school students tend to stay on their first selected program or to change the program. The theories used in the study deals with young people's choices and choosing education and vocational and life role as a student. The method was quantitative, descriptive survey. High school students in grades three, from two high schools, were asked to answer a questionnaire about perceived educational and vocational guidance. Convenience sample consisted of 162 respondents (N = 162), 86 women and 76 men.

It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.

Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

The essay, based on interviews with eight people, deals with name changes from a foreign-sounding name to Swedish-sounding name. The aim is to investigate the reasons behind the name change and whether experiences of ethnic discrimination were among these reasons. Furthermore, I explore the consequences of the name change, and whether the name change was an effective strategy to avoid ethnic discrimination. The study employs qualitative method; I carry out eight interviews with four women and four men, and analyze the empirical material by means of post-colonial theory in which categorizing, otherness and passing are significant terms. The results show that the name change takes place primarily to reduce a sense of otherness, and the discursively locked positions a foreign-sounding name creates.

The aim of this master thesis is to examine readers? advice in weblogs - frequently modified web pages with a series of archived entries. We have chosen to study a specific kind of entry that contains information about a book of fiction- not for children and young adults - and the bloggers? comments regarding that same book. The entries are published in ten weblogs that all deal with literature and reading.

Income support is often described as the community?s farthest protection, as a last economic way out.

The EU- citizenship was established in the Maastricht Treaty in 1993. This citizenship involves rights to free movement, election rights to the European Parliament, diplomatic protection and the right to petition to the Ombudsman. In my analysis I discuss the implications of the EU- citizenship for the individual. The development and legal status of the union citizenship is examined in order to give a general understanding of the implications. In addition, I conduct a case study concerning the EU- citizenship's impact on workers rights.

A large part of the time losses in production in modern manufacturing industry are a cause of unplanned interruptions in production. In this essay we have studied the effects of an unplanned interruption in production. The study was performed during one month on a press production line at Volvo Cars Body Components (VCBC) in Olofström. The effects of the interruptions have been studied on the basis of two perspectives of the environment of the production. The study started at the level of automation and was mainly done as a survey of the unplanned interruptions in production.

The aim of this essay is, due to a noted lack of earlier research together with an even more accentuated responsibility regarding the matter in question, to study the citizens? preparedness for crisis. Starting out from a number of questions regarding the citizens? responsibility andlearning from the hurricanes Gudrun and Per, the discussion concerns the terminology ofcrisis together with the question of responsibility and learning from experience.In conclusion, the source material consisting of nine interviews shows that preparedness for crisis for the affected citizen above all is related to the personal measures to create a working situation in a state of crisis. Hence, to a great extent, the citizens show consciousnessof their own responsibility.

This thesis project explores technologies that enable people to experience the world through animals' senses in order to spark interest in and awareness about the marine environment and its inhabitants. The project is carried out as part of a planned ocean themed science center. The purpose is to explore how a greater understanding of the marine environment can be achieved using interactive technologies. The thesis is based on a theoretical framework consisting of academic works on experience, learning in a museum context and sensory perception. Our proposed designs are a series of, primarily, wearable devices that translate sensory experiences and principles from the marine world to humans.
