This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

This paper is a Master thesis for the Master?s program in International and European Relations in the Department of Management and Economics at Linköping University. As the title indicates, the aim of this thesis is to make a comparative analysis of the conflict resolution initiatives that were employed in the Sierra Leonean and Liberian conflicts. The research questions are: ? What were the root causes and trajectories of the Sierra Leonean and Liberian conflicts? ? What were the conflict resolution initiatives employed in resolving both conflicts? ? Why did the Lome Peace Accord succeed in the case of Sierra Leone whilst the Abuja Peace Accord failed in bringing peace to Liberia? In order to answer the afore-mentioned questions and fulfil the aim of this paper, a qualitative research method has been chosen.

At the Women?s House in Örebro, a children?s project has started where the work method ?Oasen? [Oasis] model has been developed by two children?s educationists. The aim of this study is, with the ?Oasen? model as a starting point, to deepen the knowledge of (1) how to meet children?s central needs while staying at a Women?s House and (2) what the ?Oasen? model may contribute to the children. The theoretical framework consists of a cognitive approach to the progress of children experiencing domestic violence and a presentation of conceptions concerning children?s needs.

This study is based on a statistical analysis of fundamental key ratios on the Stockholm Stock Exchange during the period 2004-2012. In total 35 financial ratios of 90 companies were tested, ultimately five ratios remained within the 5% significance level. These ratios were ROA, P/B, Total Yield, EV/EBIT and Operating Margin. A custom made investment model was created based on the purpose to achieve a risk-adjusted excess return. The results in general did not show any significant difference in return between the model's portfolio and index.

I have with this thesis sought to understand how chick lit could be useful in the classroom in the teaching of Swedish B-course in high school. Based on the model of critical literacy I am arguing that this genre would help to meet the objectives of the policy documents which, among other things, are to critically examine and analyze various types of texts.I have found that some of these texts could be used for analyzing and critically examine the ideological dimensions of texts and cultural heritage by the model of critical literacy, and also as a counterweight to the more traditional teaching of the canonical literature as a literary historical stuff that students should learn. I have also wanted to create a basis for discussions about literature in the classroom based on the chick lit genre. To do this I have, based on three themes and questions from the model of critical literacy, tried to focus on issues that might emerge from the ideological analysis and critical review. The model aims to deconstruct norms of society, and in the work of chick lit, I wanted to show how you could deconstruct norms around gender..

The aim of this study is to examine the democratization process of Kosovo in the years after the countries independence was assured. Two central questions for the case study consist of whether a democratic improvement in the country has occurred and which factors, positive and negative, are present to further improve or impede the democratizationprocess. The study builds upon two central definitions, democratic states and democratization in order to gain theoretical background to be able to measure these two quite abstract expressions. A socioeconomic model is used to measure favorable or negative developments within Kosovos society and the findings of this model confirms the hypothesis of modernization theory, namely that increased socioeconomic development increases the chance of a positive democratizationprocess. There has been a positive democratic development aswell as socioecomic progress but since the nature of this study is merely descriptive and not explanatory, it doesnt make claims on the explanatory power of modernization theory.

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 was to determine if and how the city district of Södra Innerstaden in Malmö, by using the Skärholms model, demand their client to reciprocate. The first problem set was to see how the demand was shown in the social service act from year 1998. From there the motives behind the introduction of the Skärholms model in city district of Södra Innerstaden were researched and also if there were a demand on reciprocity in city district of Södra Innerstaden public administration. The study was conducted in an exploratory way. The method used was to describe the idea behind Skärholms model after examining documents from the public administration.

The purpose of our study is to interpret and understand the collaborative process around a regional model that is based on state developed guidelines for people with dementia. We have chosen to focus on the importance of interaction and have therefore interviewed participants in the project's steering committee. This group participates in efforts to develop a model for dementia care in Halland.The project work in Halland, to develop a joint model for people with dementia and their families was initiated in the spring of 2011 and is due to finish at the end of 2012. The Halland model has been named ?Annas led? and is about Anna and her husband Lars and living with dementia.

In recent years the liberal representative democracy has been subject of a substantial critique because of its inability to accommodate difference and createa genuinely democratic political process. One such critique comes from the theory of deliberative democracy. Supporters of deliberative democracy try to promote a model of democracy that take its vantage point in free and equal deliberationbetween all relevant actors in a political community. This model has with some success opposed the aggregative model of democracy, and in important ways turned the attention to the potential of deliberative processes.However, the deliberative model is still somewhat underdeveloped when it comes to issues of diversity and difference. This essay deals with such deficiencies by analysing deliberative democracy in the light of the critiquelaunched by difference- and radical democrats.

This study aims to examine how teachers in elementary school reason about and effectively implements special needs education. A qualitative study was made by interviewing four elementary teachers about their own role in dealing with pupils in difficulty. The material was then analyzed using content analysis. The result section is presented by the study's issue and then been analyzed against the background research. In the analysis it follows that the teachers believe among other things that there is too little time and resources to meet pupils in difficulty, the time and resources in schools is essential when it comes to meet students' needs.

Essay in Political Science, C-level, by Camila Alvarez Cea, spring semester 2010. Tutor: Alf Sundin?Reality or a Political Mirage? ? A Study of the Swedish Press Views on the Health Insurance Reform in the USA? The purpose of this essay is partly to examine whether the picture that Swedish press presents of the health insurance reform in the US, which is part of the Patient Protection and Affordable Act bill, will be of crucial importance to the possibilities that the American population has to receive health insurance. The main research question is accordingly: ?Does the picture that Swedish press presents of the health insurance reform in the USA, seem like something that will be of radical importance to the possibilities of the population to receive healthcare?? The purpose is also to examine in which model (demand or market) the opinions of the Swedish press fits. This purpose will be answered by using three specific questions asking whether their opinions differ when it comes to three criterions: organization, financing/resources and delivery systems.

When a company seeks to enter a new market, the multiple choices of possible new business relationships exist. Further, establishing new relationships is a time-consuming procedure associated with high uncertainty and high costs. Hence, if the firm does not succeed in pinpointing the most suitable business partners to collaborate with, the firm may both forfeit other possible good relationships, as well as resources invested. Based on this notion the aim of this thesis is to explore how a manufacturing company can base the selection of future dealership Business-to-Business partners by evaluating indicators of a possible business relationship?s potential to become successful. The choice of focusing on the Business-to-Business relationship between a manufacturer and a dealership company originates from being influenced by the issues facing the Swedish agricultural machinery manufacturer Väderstad-Verken AB, who is putting attention to explore the US market.

This thesis explores the position of book blogs in the literary system through Robert Escarpit's socio-literary model of the book market. Simultaneously the thesis serves as a test for Escarpit's theory: by actively applying his theory and model to a very new and contemporary actor on the book market I hoped to reach or confirm new insights into the usefulness and validity of Escarpit's work for contemporary socio-literary studies.Three book blogs were selected for the analysis and interviews were carried out with the authors. The interview questions were formulated specifically for the purpose of extracting the kind of information necessary for an analysis using Escarpit?s theory. As a complement to the interviews, statistics on the type of books reviewed on the blogs were also compiled.
