Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

I den här uppsatsen undersöker jag musikelever på gymnasiets estetiska program i Västerås, och vilken effekt undervisningen har på deras musikpreferenser. Resultaten baseras på två enkäter, en till elever och en till lärare. Undersökningen visar att eleverna till största delen är positiva till den musik de möter i skolan, men bara en mindre del av dem lyssnar på den musiken privat..

ABSTRACTThis project thesis has been written at the request of Mälardalens University, Västerås.The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course ?Aircraft Engine Technology?.                      The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate.

Students who do not achieve the different credentials that Elementary schools demand because of their mental disability, have the alternative to go to special school. Special school has a reduced course of studies, which correspond  to the students' different conditions and qualifications. The students who go to special school have done assessments to establish their need of extra help and support in their education. This paper want to show how the schooling of the children can be experienced from a parental point of view. Parents with children with special needs constantly have to make different choices to promote their children's development. In this study the parents of disabled children have been interviewed about their children's participation and intergration in ordinary schools and later in special schools.

Developing good reading skills is crucial for all pupils in school, and the reading bookis a tool for achieving that. Pupils are entitled to good reading instruction, regardless ofwhich reading level they are at, and regardless of the level of the reader they have beengiven. The aim of the study is to examine a particular teaching material and describe thedifferences that exist between a simpler and a more difficult variant of the same reader.The study is a textual analysis focused on the two readers for grade 2 from the materialDiamantjakten (The Diamond Hunt). The study shows that the two books display greatdifferences. Reading the simpler book involves a smaller amount of text, fewerdescriptive expressions, and a smaller number of words, but it does make demands onthe reader?s ability to read between the lines.

This paper is an examination of how you as pedagogue can strengthen students self-esteem. I have acknowledge that there are possibilities to do this by the art of dancing. I want to with this paper to give a deeper understanding that shows of how you as a pedagogue can strengthen students self-esteem by using dance at junior level. To answer this question I have used this questions:- Can dance strengthen students self-esteem by the art of dancing and if that is so how can this be done?- What pedagogical attitude can be to an advantage when the goal is to strengthen students self-esteem.I have chosen to use ten qualitative interviews which brings up my questions at hand.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

Small companies have fewer resources which often result in an tendency to disregard  administrative tasks. A factor that influences the company?s revenues is the control of its inventories. The purpose of the current study was to analyze which of the two options, leasing or owning your inventory, that could be justified from an economical perspective. Furthermore, the purpose was to describe the optimal inventory level for each option. To meet these objectives representatives for the company was interviewed and a thorough investigation process was undertaken, during which methodological problems were solved.  It was found that leasing the inventory was the most expensive option for the company. Analysis demonstrated that optimal turnover inventory according to EOQ (Economic Order Quantity) would amount to 65,0 thousand Swedish Krona if the company leases their inventory in comparison to 56,0 thousand Swedish Krona if the company owned their inventory.

In this master thesis we suggest a recreational directed forest management plan for the Skedalaskogen. The forest is situated 10 kilometres east of the city of Halmstad and is owned by the municipality. We have in literature and in research investigated what people like and want in the forest, how to manage the forest for recreation according to for example tree species, mixtures and density. We tried to adapt the forestry methods more to recreational thinking. We have also looked at issues like what is rare and not rare in this part of the country according to nature and forest, where people live and which connection they have to the Skedalaskogen. The Skedalaskogen is a quite big area, totally 830 hectares. The area have about 100 000 visitors a year.

Sweden will, in accordance with the EU-directive 2003/54/EC, move from post-regulating the electricity power grid-tariffs by using a fictitious grid, to a regulation in advance which uses the actual power grid as a starting point. For this purpose a component breakdown of the grid needs to be made to determine the value of the network and by that the tariff price that is reasonable for the network business in question to charge.The primary breakdown criteria is the voltage-level and type of region. Voltage-level is crucial for the cost and complexity of a grid-part, because the higher the voltagelevel is, there are more and stricter laws and rules to follow. This work is limited to the distributionpart of the grid, in other words voltage levels from 20 kV and below.The type of region is crucial to the type of components you can and want to use. In city environments both overhead-wires and independent substations are undesirable for both practical, safety and aesthetic reasons.

AbstractSchool is taking on a great responsibility in mediating knowledge of mathematics as technology is assuming greater importance in our everyday life. The aim of this study is to examine how the teachers in year F and 1 view their teaching of mathematics from an individually adapted perspective. I have based my research on different factual study books within the education for younger children?s learning of mathematics, and have from an individually adapted perspective made a comparison between theory and practice. The empirical data has been obtained through interviews with six teachers, three pre-school teachers and three teachers, working with pupils in year F and 1.

It is the curriculum and the syllabus for history that decides what the classbooks will include. The intention with this paper was to found out what Swedish and Norwegian classbooks writes about the union between Norway and Sweden in 1814-1905. The result has been compiled from a study with teaching materials. Two Norwegian and two Swedish books which was written for the elementary school was used in the study. The text in these books has been analysed from a number of questions.

The aim of the study was to investigate feeding routines, management, health and level of activity of riding horses in Sweden. This was obtained by a survey requesting information from owners who kept horses at a non-professional level. Owners to approximately 500 horses were contacted and the usable response of the survey was 56 %. The dominating breed in the study was Swedish warmblood (38 %). Fiftytwo percent of the horses were geldings, 45 % were mares and 3 % were stallions.

Syftet med denna uppsats var att undersöka hur kön görs i sex stycken vägledningssamtal på gymnasiet. Med stöd av några utvalda könsteoretikers forskning analyseras samtalen som utförts av tre stycken olika studie- och yrkesvägledare på tre stycken olika gymnasieskolor. Varje studie- och yrkesvägledare samtalade med en tjej och en kille i årskurs tre och deltagarna valde själva ut vilka elever som spelades in på band. Resultatet pekar på att studie- och yrkesvägledarens förhållningssätt delvis skiljer sig åt beroende på elevens kön. Genom att undersöka samtalsinnehållet och jämföra detta med normativa föreställningar om kön så ges olika exempel på hur kön görs i samtalen.

The amounts of theories that deal with naval warfare are many. Several of those are developed under the previous century when tactics and technology were in the eve of development. Many of modern thinkers within science of war often refer to older but recognized theories. The purpose of this essay is to examine if the old but recognized theories are of current interest in modern naval warfare. The questions that are used in this essay are, what is the characteristics of the war of Yom Kippur with Mahan?s offensive and Corbett?s defensive as a starting-point and are there any of the theories that are prominent.
