In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..

Storage of biomass is often associated with problems such as heat development, dry matter losses and reduction of fuel quality. The rise in temperature can potentially cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles can cause health problems in the surrounding. The dry matter losses and reduction of fuel quality can have economical effects. The aim of this thesis project is to develop guidelines on how to store large amount of biomass at Vattenfalls heat and power plants in an optimal way.

The purpose of this essay was to find out how leaders in micro service firms practice HRM and identify which HRM related problems they experience in their leadership. A case study consisting two cases was carried out. The study has shown that leaders in micro service firms use a highly personalised, informal management and involve their employees in the firm?s development. The findings were that leaders of micro service firms do not have any theoretical knowledge of HRM practises because of lack of education.

This essay has discussed and analyzed a draft for an idea about a network called EduSync. This idea is based on that teachers and students, attending and holding courses, all over the world should be able to find and interact with each other. EduSync is founded from a new learning theory, connectivism. Interviews, participation in a conference and two workshops have been used to gather information and different points of view concerning e-learning, for example possibilities and problems with this idea of a network.  A comparison of web communities and e-learning environments that exists today was also done. The gathered information from persons as well as literature resulted in a discussion concerning learning and what would or would not be possible with the creation of EduSync.

The aim of this thesis is to describe and analyze the geographical distribution of everyday criminality in the town of Borlänge during the year 2002 and to analyze which measures to be taken in the physical social planning to decrease this everyday criminality there. The term everyday criminality is here to be understood as those categories of crime that appear most frequently in the records of reports to the police every year. Here two kinds of crime have been in focus, thefts from cars and office burglary.In fulfilling this aim two main questions have been answered. The first one is how the everyday criminality was distributed geographically in the town of Borlänge during the year 2002. The second one is which measures to be taken in the physical social planning to decrease this everyday criminality in the town of Borlänge.In order to answer the first question a spatial autocorrelation analysis, Local Moran LISA has been used.

Abstract The extraction and usage of energy give rise to immense environmental problems which helps to accelerate climate change. Energy is an important resource for the community and there are a variety of different types of energy sources available, that are either classified as renewable or non-renewable energy sources. The usage of renewable energy sources cause less environmental impact than the usage of non-renewable energy, which in turn means that the energy?s strain on the environment is strongly affected by the type of energy source used.The aim of the study is to describe to what extent attitudes towards renewable energy are affected by whether the individual is male or female, by examining the hypothesis regarding how women have a closer connection to nature and to a larger extent shows on an pro-environmentally friendly behavior than men, and if it also can be detected on issues related to renewable energy and thus imply that women have a friendlier approach towards renewable energy than men. A number of ecofeminist believe that women have a stronger bond with the nature through her embodiment as a woman and by her maternal role, which according to previous research also leads to the fact that women shows on a more extensive environmental behavior.Through a qualitative research method in the form of semi-structured interviews has three female and three male respondents been asked questions with regards to the environment, individual responsibility and energy.

The purpose of this essay is to try and bring clarity to the question, what is Chick Lit and which factors make it so popular. My thesis  endeavors to explain that it is not only the promise of light entertainment that draws the reader, but also the possibility that in an easy way they can read about existential questions such as self-development  and life -choices.As well as mapping out Chick Lit´s specific characteristics, followed by previous research on the subject and the litterateur?s history, I have found it interesting to discuss the female characters, their personalities and life choice?s against a backdrop of existentialistic philosophy.In my research of this form of literateur I have discovered that chick lit often deals with existential universal problems, and that in order to be entertaining these books must contain a serious element..

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).

The purpose of our report was to analyze the effects of youth drug abuse on the families concerned. Youth drug abuse made us wonder about the effects on the family as a whole, of those involved with drug abuse. To answer this question, we decided to employ an empiric study in the form of interviews with four teenagers, five parents and four drug counselors. Because our intent was to understand rather than try to measure the problems involved, we decided on a qualitative method. Our method built upon semi-structured interviews using open questions, where the interviewees were free to express their own thoughts and opinions.

Hemp is an ancient cultivated plant that came to Sweden in the 1st to 2nd Century and was particularly interesting for use for food, clothing and building materials. Over time, other applications have been developed for hemp, e.g. in energy and health products. Interesting new uses for hemp continue to be identified and this fascinating plant has incredibly versatile applications.In this project, seed production of industrial hemp in Sweden was studied and evaluated. Five different methods are described, four of which are proven under Swedish conditions.

Detta arbete handlar om förekomsten av verklighetsbaserade matematikuppgifter i matematikläroböcker. För att få underlag till undersökningen har vi granskat fyra svenska läroböcker i matematik, samtliga avsedda för årskurs sju. Undersökningen är fokuserad på textuppgifter, som vi valt att granska genom textanalys. I samtliga läroböcker fann vi att textuppgifterna var underrepresenterade. Av textuppgifterna var det en stor andel som baserades på verkliga händelser.

On a highly competitive market, quality is an important aspect to take into account, both in terms of goods and services. The Swedish timber market is very competitive and to achieve long-term success focus on the customer, in this case private forest owners, is a prerequisite. SCA Skog AB Jämtlands forest management administration is dependent on the acquisition of timber from private forest owners to fulfil their mission to the supply of SCA's paper and sawmills in Sweden with raw material. To be able to develop the cooperation with private forest owners, the administration investigates their quality management by measuring the customer satisfaction index (CSI). The purpose of the study was to identify a practical and systematic method to handle deviations and suggestions for improvements to achieve a higher customer satisfaction.

Everything has changed, yet everything is the sameUsually, there is no reason for people to think about death or illness, although it is a highlynatural part of life. Most people live in health without major problems. When something does happen, people assume it will be at the end of their life and then it will be a natural part ofgrowing old. Yet some will get the notice or the feeling that something is not the way it should be, it can be something they can live with or they may have to face death.The work concerns the body?s fragility and feelings about human vulnerability.

This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.
