In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

Abstract Background: The World Health Organization has expressed a great concern about the increasing prevalence of childhood obesity. Region Västra Götaland (VGR) has developed a web based program to support school nurses in their work to promote health among children with obesity. Previous research on childhood obesity emphasizes the importance of support from nurses and how their work is organized. Aim: The aim of the study is, firstly, to explore school nurses experiences with health promotion work among obese children. Secondly, to investigate whether school nurses use the salutogenic theory of health.

The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

The print- and mailroom at Gefle Dagblad (GD-tyck) is handling an increasing amount of commercial jobsalong with the newspaper production. Investments have above all been done in the mailroom to be able tooffer commercial costumers a higher degree of finishing and there are plans to expand further in the commercialmarket. GD-tryck is of the opinion that they need to secure the quality of their production to be ableto do such expansion, which is the reason why a quality system of some kind may be appropriate. Howeverthere are no plans to certify such a quality system according to ISO 9001:2000.In this exam report the present methods of working have been analysed from a quality perspective.Suggestions on how GD-tryck should be working with quality development is presented in the fields whereshortage of quality has been discovered. The suggestions taken together do not form a quality system butcan be looked at as ideas of approach to quality fields that have to be developed if a working quality systemshall be accomplished.Many of the quality fields that have been discussed do not have anything to do with technical qualitydirectly but are in some degree requirements for a working quality system.

This thesis has focused on digital born personal archives; how they are different from analog paper archives and possible ways to overbridge these differences. It is also studied how archivists and librarians are dealing with digital archives, what they think about new proactive solutions when collecting private papers and collections and positive and negative effects with this way to work. The thesis is delimitated to only private collections and digital created material. It do not concern digitized material or electronic documents in government or business organizations.The challenges in digital curation and administration are discussed in aspect of the Records Continuum Model. The empirical material is also put in relation to research in Personal Information Management and identity theory.

The purpose of this bachelor thesis is to examine the methods public libraries can use in order to market youth services. It is also a chance to evaluate an untested marketing model adapted to public libraries. Young people are one of the most difficult groups to attract to the library and thus librarians need adequate methods to deal with this problem. We have interviewed librarians, carried out observations and examined documents in accordance to the triangulation method. Before one can begin marketing the libraries one ought to know of how marketing is done and the principles behind it, therefore we have given a simple explanation of marketing and marketing theory.

At the time being there is limited experience within turbine decommissioning in Sweden and the economic effects are unknown. Despite this, there are expectations that revenues generated by sales of materials will cover decommissioning costs. The model developed identifies thirteen parameters that vary between different types of turbines and that affect the economic consequences of decommissioning. The three most important parameters are turbine location, tower material, and the scope of decommissioning. Trends in the wind energy industry show that these three factors are developing in a manner that increases decommissioning costs dramatically.

In Sweden there are many kinds of effort given youths with behavioral problems, one is institutional care. International research display a varying kind of results from this type of treatment. The aim of this study is to examine and illustrate which central components that results in positive treatment, but also starighten important components in KBT. On the basis of research results, important components for positive treatment have been illustrated as; the therapeutic relationship, the integrity of treatment, prosocial-contacts, positive climate in treatment, the continual of treatment, how to bring treatment to an end, the responsivity principle-the principle of need-the risk principle, learning and KBT.  Research also aims to investigate whether these components could be identified in the daily work of youth treatment on institution. This through a qualitative approach including six interviews held with staff working in treatment facilities.

This thesis studied which factors affect political participation among people with physical disabilities in Sweden.? The aim of the study was to test how Civic Voluntarism Model should explain the low political participation among people with physical disabilities in Sweden, through deep interviews.? Following research questions has been studied in the thesis:? How can the Civic Voluntarism Model, based on the time, communicative skills and economic resources, explain the low political participation of people with physical disabilities in Sweden??Which other factors, linked to accessibility, discrimination and legislation, are needed to further explain and understand the barriers to political engagement and participation for people with physical disabilities?? Results about treatment, clearer legislation, economic possibilities and inclusion was central. It became important to considered that where is differences in which capabilities where are to political participation. The CVM could partly explain the low political participation among people with physical disabilities. It needs to be complete with external factors; accessibility, discrimination and legalization, to make more inclusive explanations.? .

We are living in a multicultural society where people from other countries and other cultures are coming to Sweden, including children. Regardless of reasons why these students have come to Sweden, it is common that they are newly arrived and have to learn a second language, in this case Swedish. This will be a challenge, opportunities and difficulties for the student, students? families and for the school and their staff.The purpose of this essay has been to illumine the teaching methods, models and what materials are used by teachers today to contribute to the best possible second language learning for newly arrived students. In this essay the focus has been on one theory and several model-based approaches.

The aim with this study is to achieve an increased understanding and knowledge about terrorist groups. The factors that the study come to be focused around is the groups' objectives, their organization, which enemies they have and with which means that they use for there terrorism. In order to respond to this aim the four different terrorist groups, Colombian revolutionary armed forces (FARC), Baskien - our native country and our freedom (ETA), red Army fraction (RAF) and al Qaida is studied.To achieve the aim of this study the methods qualitative text analysis and comparative method is being used. It is designed also within the framework of this study a categorization model that is used as method in order to do a division of the studied groups based on their objective, enemies, organization and means. The model is also constructed to be used in order to analyze others terrorist groups than these current groups.The result of the study is presented in the categorization model on page 32 in the essay..

In this essay, I have examined what has been studied and presented in the theory of ICT in schools. I have based my theory on Arne Trageton?s book Att skriva sig till läsning ? IKT i förskoleklass och skola (2005) and theories on children?s reading and writing development.The purpose of this study is to determine how teachers and children experience teaching with Trageton?s ICT-based model Att skriva sig till läsning and whether the model is beneficial for children's first reading and writing.Through qualitative interviews with two pedagogues from the same school and some children from first grade, I have received answers to my two questions:How do pedagogues and children experience ICT-based teaching in the context of children's first reading and writing?How do pedagogues experience the reading and writing development in first- and second-language students when using ICT-based teaching?The results showed that both pedagogues and children were positive about the model in which the computer was used as a writing tool in learning to read and write. The teachers felt that the model was suitable for all children according to their conditions.The children saw the writing as very enjoyable. For the ICT-based teaching to work properly, the technology has great significance.

The jetengines of today are growing in complexity. Reliability for aircraft engines are of extreme importance, mainly due to safety reasons but also economical ones. This master thesis deals with faultdiagnosis in the turbine section of RM12, the engine used in Saab/BAe's Gripen. Three different faults which can occur in the turbine section was studied. These faults are: clogged fuel nozzle, hole in outlet guide vane and sensor fault.
