The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.

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.

Since 1 January 2010 it is a requirement to use the European standards, Eurocodes, in Sweden when constructing bridges. One chapter that has caused an extra amount of problems for the engineers is the one about fatigue analysis, which resulted in us doing this thesis.To do this we had to read all of the Eurocodes that direct, or indirect deals with fatigue and calculating of such. We have read the background documents for the Eurocodes and master?s thesis in the subject. We also studied the calculations of bridges constructed by different construction firms.We have chosen to limit the thesis to discuss only road bridges made of concrete due to the lack of method for verification of concrete in the national appendix.

Studies in the recent years have showed that the preschool playground is important for both the physical and emotional development of children. The Botkyrka local government has decided to improve their preschool playgrounds in order to take advantage of these studies. The administration of childcare and education in Botkyrka is arranging a network between the different preschools where they work together to improve their outdoor environments. The network is arranging workshops and seminars where people from the different preschools can come and gain inspiration for improvements of their own preschools. The administration of properties has created a document where they describe the changes that are supposed to be made to the different outdoor environments. Through the administration of properties and the person who is responsible for the outdoor environments I was introduced to their work with the preschool playgrounds.

Sjuksköterskans omvårdnadsarbete har förändrats genom tiderna. I början av 1900-talet var sjuksköterskeyrket ett kall, vilket huvudsakligen innefattades av att se till att smittosamma sjukdomar inte spreds vidare, samt hålla patienten ren. Idag innefattar sjuksköterskeyrket ett mer komplext arbete där administration, specialistvård, teknik, patientnära omvårdnad samt kontakt med andra yrkeskategorier och instanser ska vävas samman. Syftet med den här pilotstudien var att belysa hur fördelningen av sjuksköterskans arbetsuppgifter ser ut över dygnets 24 timmar. Strukturerad observationsmetod användes för datainsamling.

Syftet med denna litteratur studie var att undersöka vetenskaplig litteratur om hur sjuksköterskan och övrig sjukvårdspersonal bemöter och vårdar patienter med missbruksproblem. Begreppet missbruk innefattar alla former av missbruk av både narkotika och alkohol. Artiklarna skulle handla om patienter med ett missbruk och deras möte med vården. Litteratursökningen har skett i följande databaser: Science Direct (Elsevier) PubMed , Blackwell Synergy. Urvalet skedde utifrån relevans till syfte och frågeställningar.

This paper is about sensemaking. By using sensemaking we have derived bankruptcy factors from business leaders? own statements about their bankruptcies. The focus in this paper is to ensure how business leaders create meaning about the bankruptcies, which is also our research question.To make the study feasible, we used a method that corresponds well to the purpose of our work. The collection of data started with collecting a number of newspaper articles with direct quotes from business leaders.

The aim of this Master's thesis is to examine the information use among Swedish backpackers, both prior to departure and while travelling. The questions posed in this study are; which artefacts did the backpackers use, in what way were those used as tools of mediation within their social practice and how does a presumptive interaction between backpackers and information sources appear? The empirical material consists of interviews, held with eight backpackers, concerning their information use. The interviews reveal that a number of information sources are being consulted. The most commonly used sources identified in the empirical material are guide books, advice from other backpackers, fiction, TV programmes and periodicals.

The purpose of this master?s thesis is to study resource allocation among district libraries within Stockholm?s City Library (SSB) on three different occasions ? 1996, 2001 and 2005 ? and to examine whether there exist any inconsistency between the state of the allocation of resources and what might be considered reasonable. During the course of the study, it became apparent that some measurements are more relevant than others when determining whether the allocation of resources is reasonably fair. The most relevant ratio is the share of net cost per capita in relation to population and the population?s composition of children, youngsters and persons with foreign background as a result of relevant political governing documents giving priority to these three groups.

The purpose of this report is to find a model of statistics for construction and demolition waste, which makes it useful for the local manager at the building site. The intention with the model is that it will be used as a support of the local manager, to direct his project towards reduced strain of the environment. The model will also be used to make it easier to control that the claims from authority and aims for the environment are achieved. To familiarise with the subject waste handling within the building and construction sectorI have done a literature search. I have also been studying rules and regulations regarding the waste handling.

The purpose of this study is to explore the differences and similarities regarding the causes of and approaches to bullying among a number of girls and boys in third grade in two schools. One of the schools is in a mono-ethnic area and the other in a multi-ethnic.The purpose isto compare the results between the schools and the questions proposed are:What is the reason for the bullying?What are the differences and similarities in existing opinions on the practice of bullying?What are the differences and similarities of students' opinions on bullying in a mono-ethnic and in a multi-ethnic school?I have chosen to use gender and ethnicity theories and the study was conducted through qualitative group interviews. The results have shown that boys' explanations for bullying are more aggressive than girls, although approaches to bullying were more related with violence among boys. The multi-ethnic school uses more direct bullying compared to the mono-ethnic school where indirect bullying occurred more often.

Background:Studies show that when nurses are experiencing problems in the care of non-Swedish speaking patients, it is often due to obstacles in the communication. Studies also show that a prerequisite for adequate care is that there is a basis for a direct communication. Nurses perceive interpreters as an important link to the patient when they do not share a mutual language, the nurses perceive interpreters as a bridge in the conversation.Aim:The purpose of the study is to describe nurses' experiences of the quality of assessments done with the help of an interpreter.Method:The study was conducted through interviews with ten nurses, working at psychiatric clinics. Qualitative content analysis was used for the analysis, which resulted in five categories.Results:The analysis resulted in one theme: "it´s the interpreter who tells me and have not the feeling that the patient has" and five categories: "shades of the language", "conversation structure", "the interpreter's competence", "interpreting implementing" and "the interpreter's gender and origin". The nurses experience working with interpreters as a challenge.

Japan's foreign and security policy has seen some substantial changes as a result of events like the first Gulf war and 9/11th. This has been taken as proof, by some, that Japan is abandoning its antimilitaristic stance and pursuing a more traditional hard power role through military means. This essay aims to explore if these shifts have coincided with any substantial shifts away from antimilitarism, which has had a strong influence on the country's security policy since the end of WW2.To do this I use constructivist theory, specifically regarding the impact of norms and identities on states security policy and briefly look into the problem of actor designation. The thematic focus is on security policy, from a narrow perspective, and thus I examine areas like the input and output to the Japanese military and the actual applications of this force. State identity is used to explore the prevalence of nationalistic sentiments and support for anti militarism in the public opinion and the political elite.The result of this study points to the further relevance of constructivist theory and especially the application of norms and identity.

Kronoparken is a multicultural area with more than 100 different nationalities. Since we know that girls with a foreign background participate less in sport than girls with Swedish background do, we think it would be interesting to examine what kind of thoughts and experiences young girls on Kronoparken has about sport.  The purpose of this study is to examine what the girls think about the activities that are offered today. We also want to examine their thoughts about sport and gender issues.Since the aim is to identify the girl?s experiences around current activities and find out what ideas they have to improve this, we think a qualitative method is best suited. We have chosen to do interviews with two focus groups.
