The goal of this master thesis is to show the benefit of using computer games of the type First Person Shooter, FPS in the field of military simulations. The main focus in this is around a couple of topics. Creating the AI that controls the behaviour of the computer-controlled characters, the bots. Create an environment where it is possible to supervise the bots and also design a framework that enables cooperation between a group of bots, a squad. The result is Total Unreal Studio, TUS, a program where it is possible to add bots to a squad, connect them to a game server and inspect what the bots are doing.

In 1990 the education training program for teachers working with children with special needs was changed. One major difference in the new program compared with the former one is that the specialized teacher is now mainly supposed to supervise teachers instead of teaching pupils who have learning difficulties. The aim of this qualitative interview study has been to find out what the specialized teachers think about there education, and how this could influence children with cognitive disabilities in special schools. I have interviewed six teachers who specialized in teaching pupils with cognitive disabilities. Three of them where educated prior to 1990 and the others were educated after 1990.

Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.

The purpose of this paper is to analyze the employers? responsibilities for rehabilitation ofemployees in Sweden, who due to illness or injury are unable to work. The process of therehabilitation will be analyzed in a gender perspective. A minor comparative study aboutrehabilitation in Denmark will also be carried out. The purpose is to see how the process ofthe rehabilitation is designed for those who due to illness or injury are unable to work, whichfactors that affects the rehabilitation and which differences there are between Denmark andSweden regarding the employers responibility for rehabilitation.

The aim of this study was to identify and make transitions in Swedish preschool-class-9-years elementary schools visible with a special-needs educational perspective. Transitions in focus were those between preschool-class and primary school, between grade three and four and the last between grade six and seven.In the 1960?th Swedish elementary school were devided into three levels; primary school, intermediate level school and upper level lower secondary school. Those levels were officially removed when the curriculum of 1994 was introduced. However, in some way such levels still exist, for example in organisation and structure of schools, the curriculum and teacher education.How did school leaders design transitions between levels and which tools were used? What kind of information was transferred to help children with special needs and what was the role of the special pedagogue in the transition process?The study was a combination of a quantitative and qualitative method, a questionnaire survey complemented with qualitative interviews with special pedagogues in three schools in a middle-sized Swedish town.The result of the study shows that schools in focus had a work plan.

The purpose of this study is to investigate the children?s mathematics learning through play. The questions to be answered are: how can teachers facilitate children?s mathematics learning through play? How can play affect children?s math learning? Are the children aware of the role of play in their mathematics learning?My method is based on interviews and observations. My informants are three teachers who work in two different preschools.

This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.

The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010. The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing. In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment. The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment. Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

This paper examines how and if the understanding of wedding photography has changed during the shift of technology - from analog to digital photography. It examines if the changed conditions due to the shift of technology have changed the habits and conditions for the photographers working with wedding photography. It furthermore examines what impact these habits and conditions have had on the pictures of weddings. The investigation is based on interviews of six photographers that have worked professionally before and after the shift of technology, as well as of pictures by the photographers taken before and after the shift of technology.Use of time and space has changed due to the shift of technology. The change has also had an influence on hierarchy among the photographers.

Overweight and obesity in children is an extensive and accelerating problem in the western world. The risk factors for overweight are well- known and well-documented. Focus should lie in the prophylactic work in order to prevent overweight and obesity in preschool children. The aim of our study has been to highlight the role of the district nurse in her/his work to prevent overweight and obesity in preschool children. The study was carried out through studies as a literature review.

The aim of the present paper was to see why a recommended course of action is not always followed in the way it is supposed to. The paper deals with a new method (SFA-metoden) used by The Social Insurance Agency in working with sick-listed people. Aspects that are elaborated on are local effects of the method at its introduction, case managers work conditions, and control of the implementation of the method. Two different methods of investigation have been employed. On the one hand, previous reports on the method have been analysed, and, on the other hand, two focus groups interviews, one consisting of case managers´ working with the method, and one constituted by their supervisors have been carried out.The results have been analysed in accordance with, on the one hand, the theory of street level bureaucrats and, on the other hand, certain concepts applied in the new institutionalism.

We read different kind of texts every day. We can for example choose to read a book or to watch a film. While we read we can receive and interpret texts. That?s means, for example, that we can have different envisionments about the drama and the film based on it. Based on Langer?s reception theory about ?envisionments?, I?ve wanted to examine and clarify the differences and similarities of envisionments between two texts.
