As break downs of production transformers are costly and often result in long outages it is essential for reliability of operation that the transformers are manufactured to be robust. The aim of this M.Sc. thesis is to investigate if deviations should be made from the standard IEC 60076 ? Power Transformers in order to describe a robust large power transformer for procurement.The investigation has been conducted in three stages. In the first stage a definition of the term robust was developed in consultation with the client Vattenfall Vattenkraft.

Today, branding is not a phenomenon but rather a prerequisite for a brand to be able to both survive and grow stronger. During the last couple of years, personal branding has come to be an established term, just like corporate branding. With the growth of the social media and the thousands of ways to interact with each other personal brands face great competition. It is more difficult than ever to maintain a strong brand, partly because of this. There are several growth options for brands.

!is began as a product design challenge, which stipulated broadlythat the designer be ?inspired by a subject?, whose ideas would leaddown a path of product idea evolution. From there, the goals forthe end-product would undergo rigorous revisions, re-de#nitionand re#nement. !e end-product itself would be the result of anentire thinking process.!e subject I have chosen is: Time. I want to challenge and evenalter our conventional sense of time, using principles ofdesign.

Chronic illness is associated with conditions that may result in psychological ill-health in the adolescence. Consequently there is a need for development of preventive psychosocial support interventions for this target group. The objective was to develop, implement, and evaluate the effect of supportive intervention group program for teenagers suffering from chronic illness - aiming at increasing quality of life and supporting mental and physical health. Method: Six different intervention groups were conducted between 2007 and 2011, age 13?17.

This master?s thesis investigates how six Swedish public libraries integrate equality aspects in their user oriented activity. The theoretical starting point for the study is that Sweden is a part of a gender system characterized by gender separation and male superiority, as described by the Swedish historian Yvonne Hirdman and theories that argue that femininity and masculinity are social constructions. Another starting point is that the library sphere cannot be separated from the gender inequality in society. Since the library is part of a gender system that value individuals who are seen as males and separates men and women, some of the library users may be neglected.

National and international studies, such as PISA and TIMSS, which are part of the national evaluation system, are carried out continuosly. Skolverket, in collaboration with researchers, are responsible for the implementation, evaluation, and analysis of the studies. National results show an increasing percentage of pupils who do not reach the goals in mathematics. The last completed international studies PISA 2009 and TIMSS 2007 show an impaired trend of knowledge, in international comparison. Moreover, studies also show that the differences between schools and also within the same school in Sweden have increased.

A detailed dam safety evaluation (in Sweden called FDU) was performed in 2009 by WSP where stability control was performed for Långströmmen power plant with associated spillways. This evaluation concluded that stability could not be ensured, and risk of sliding occurred. The evaluation is based entirely on the recommendations outlined in RIDAS, the power companies guidelines for dam safety, and it is clear that extensive renovations are necessary to stabilize the dam.In this work, the stability will also be checked with guidance through new proposals on guidelines for concrete dams sliding stability, ELFORSK?s report 08:59. This report considered the guidelines in RIDAS as oversimplified, both from an international perspective, but also with regard to the current state of knowledge regarding dam safety.

This study investigates the individual usage of the Dublin Core metadata format in three Swedish Subject Based Information Gateways, SAFARI, Svenska miljönätet and Svesök. The authors also present the reader with an overview of the metadata concept and explains in particular the Dublin Core Element Set. The approach to the study is investigation of Dublin Core application from the viewpoint of three major issues, user friendliness, interoperability and quality control. The study includes an in-depth comparison of the three different metadata templates, as well as interviews with people in charge of the metadata production at the respective SBIGs and users of the respective SBIGs« templates. The study shows that the three SBIGs are more similar than they are different.

The intention of this essay is to describe the problems with loss of books at three Swedish University libraries. It?s based on interviews with librarians. The library codes of ethics, the library law and the terms of reference of the libraries are central for my understanding. Interview results: Little was being done to stop theft.

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

The aim of this Masters thesis is to examine the use of IT, that is the Internet and other applications of personal computers, among seniors 65+. It also deals with issues of access to IT for seniors in public libraries. The theoretical background of the study consists of Rogers "Diffusion of innovations", Hektors categories of information activities, and the Swedish IT-commissions categories of motives and prerequisites for the use of IT. The research questions focus on factors motivating the use of IT, the extent and the purposes of IT use, the consequences and the barriers that IT-users experience, and views on IT in public libraries and IT courses, respectively. Qualitative interviews were carried out with nine senior IT-users.

A purchase decision can be seen as a multifaceted context that raises many unanswered questions. Understanding the consumer's evaluation of alternatives is complex and should be studied at a deeper rather than wider scale. There is a problem for retailers to understand how the consumer manages a purchase decision in a retail setting with durables goods that generates a higher effort. The aim is to describe the decision rules used by the consumer and how they are expressed in this context. A better understanding of which ones they use and how they are conveyed will help retailers to create effective marketing solutions that generate positive outcomes as increased profitability and customer satisfaction.

Den här undersökningen handlar om hur flickor respektive pojkar i en årskurs fem använder värderande uttryck i sina narrativa texter. 22 elevtexter, 11 skrivna av flickor och 11 skrivna av pojkar, har analyserats enligt Appraisal framework. Jag har undersökt hur många och vilka typer av värderande uttryck eleverna använder och även hur de har fördelat uttrycken över texterna i förhållande till den narrativa berättelsestrukturen. Resultaten visar att flickorna använder värderande uttryck i större utsträckning än pojkarna. Fördelningen över de olika typerna av värderande uttryck liksom fördelningen av uttrycken över texten är dock ganska likartad för flickorna och pojkarna.This study concerns the use of evaluation in narrative texts written by pupils in fifth grade.

The purpose of this master thesis is to investigate how the public library can support adult learning through collaboration with other actors in the community. This is done by examining the activity of Linköping municipal library towards the user group adult students. The questions raised consider; the political view of supporting adult learning, the role of the public library, who are the actors in Linköping, the experiences of collaboration and finally what promotes and restrains collaboration. The investigation is done as a case study with qualitative methods. The qualitative methods was found to be the most appropriate for this study, since the majority of the empirical material has been collected through interviews.
