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 availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.

In 2005 we made a research in a Swedish community board about their view on the political and ideological intentions of ?a school for all?. The results from that study were the background to this research.The aim with this research was to find out how principles in the same community were thinking about ? a school for all? and if they were leading a development towards ?a school for all?. In that context they were given the opportunity to explain their definition and reasoning about ?inclusion? and ?integration?.

Community Supported Agriculture (CSA) is an unconventional model of agriculture expected to contribute to a more sustainable food supply and a sustainable landscape; the development of rural areas; a stronger relationship between producer and consumer and a healthier diet. This study, with a focus on food production and the link between the producer and consumer, describes the origin and current development of CSA in Sweden, including the prerequisites for CSA in a Swedish context. Organizations and entrepreneurs working with CSA and related projects are identified and interviewed. The notion of CSA in Sweden is still in its infancy, but a rapidly growing interest currently can be detected. The fact that the identified CSAs are found in different Swedish regions with variations in degree of urbanization and intensity of agriculture indicates that the prerequisites are there for the concept to grow, both in rural as well as urban areas.

The aim of this study is to investigate variations of conceptions among prison librarians, concerning mediation of information from an ethical perspective. We have performed interviews with nine librarians and used the phenomenographic approach when analyzing the material. Sixteen categories of conceptions were found, distributed on four aspects of the phenomenon, the act of mediating information to inmates. The results show a variety of conceptions among the librarians. The four aspects cover conceptions about the inmates as users of the library services in prisons, conceptions about the information need of the inmates, conceptions concerning policies, guidelines and laws and conceptions about information access in the prisons.

Information about the risks involved shall be distributed to the people living in the area nearby to potentially dangerous installation. Swedish law stipulates strict requirements on what information should be supplied, but the law itself does not give any guidance on presentation. The main purpose of the study is to give recommendations on how to improve the information brochures. Within the study, eight people working with risk information have been interviewed and seven different risk information brochures have been studied. Also, a theoretical analysis and a practical experiment were performed using brochures from two municipalities.

In this study we are focusing on Instagram and marketing. We want to know how Web 2.0 and social media creates a new place for companies to market themselves and mostly how they are using the social network Instagram. The amount of swedes using Instagram is 28% and that is the double of what it was a year ago. This creates a whole new place for companies to market themselves and most importantly; it?s free.Our question at issue is In what way is fashion and interior design companies using marketing and Web 2.0 on Instagram and how does it reach individuals? To get an answer we contacted eight different companies and asked if they would like to answer some questions.

Researchers points out that social media has become a powerful venue to spread news, both for the news business and the users. Although the news diffusion has become a phenomenon to be reckoned with, we have found no research in Sweden about what motivate users of social media to share news.This thesis work therefore investigates news sharing on the social network Facebook by examining user motives in the light of the media theory uses and gratifications. A web survey was conducted and distributed to students at a Swedish university. The result showed that expression was the strongest motive to share news on Facebook, and the item that was highly valued by the students was to give other valuable information. The result also showed that other motives for sharing news was socialization, information, status and entertainment. .

According to modern theory, PR is seen as something that creates value for majority of products. The art market is a market that is characterized by several actors in different value chains, where transparency is low and art critics, or PR creators, have a certain amount of impact on the view of art, at least had so historically. But how does PR vs. art galleries´ own marketing (art brochure) affect the view and price consideration of art and artists for non-expert art spectators? After performing a large quantitative study, we can conclude that PR has negative to no affect on the view of art and the artist compared to the case when the spectator did not receive any information prior to viewing an art piece.

There is much research into the reasons why a temporary pain, in some individuals, becomes chronic. Many of the causal factors linked with pain also seems to coexist with social anxiety, public self-consciousness and, to some extent, private self-consciousness. The purpose of this study was to investigate and identify possible patterns of self-consciousness (private and public), social anxiety and pain. This was done by a cross-sectional study in which a questionnaire was distributed to students at Örebro University. A total of 302 completed questionnaires were received.

The aim of this thesis is to get a better understanding of how the management control system works at V&S Distillers. V&S Distillers went through an organizational change in the beginning of 2005. The marketing function went from being a country-driven to a category-driven organization. Among other things this resulted in increased cooperation between employees in different geographical locations. We aim to analyze how a geographical distance affects relations and the use of management control.
