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.

Genreblandning har de senaste fem åren blivit en allt större del i hur datorspel designas. Den här uppsatsen är en studie i hur genreblandning kan appliceras i en spelproduktion och hur denna produktion och dess genreblandning uppfattas av en grupp utomstående som sedan spelar spelet. Den blandning som studeras är den mellan genrerna role-playing game, dual-joystick shooter och minigolf. Resultaten från den enkät denna grupp sedan svarar på visar att genreblandning mellan de valda genrerna fungerar trots deras olikheter sinsemellan, men att det är mycket viktigt att spelets övriga element inte försummas till förmån för genreblandningen. Det framgår även att den grad till vilken de tre genrerna blandas i spelet respondenterna testar inte är den maximala..

This thesis examines the retrieval effectiveness of two Web search engines. The two search engines are chosen to represent two different types Google as a broad general search engine and Dogpile as a broad general metasearcher. Twenty queries have been used and the first twenty hits for each query were evaluated for relevance. The queries were invented by the authors, based upon their interests and information needs. They were expressed in a general manner, by using one or several keywords, in accordance with the simple search mode available for each search engine.

To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.

Yahtzee is a popular dice game around the world. The complexity makes the game interesting to play and analyze. This report compares the effectiveness of the mathematically optimal strategy with a strategy that can be used for casual play. The rules used are those of the Nordic variant Yatzy, in which a few but important rules are different from the American Yahtzee. To evaluate the everyday strategy 100,000 games was simulated in a java program written specifically for this purpose.

This report describes the results of the project "Concept development of jet engine inspection plugs" carried out in the spring of 2008. The work was done at the department of product definition at the company Volvo Aero in Trollhättan. The objective of the work was to develop concepts for a "Volvo-unique" inspection plug. The work is part of Volvo Aero's focus on proprietary (self-developed) technologies. Inspection plugs can be found on virtually all aircraft engines and gas turbines.

The value of game for hunting from a social economic viewpoint is an interesting topic that is currently being investigated in a Swedish research program. The amount of damages that the game stocks cause to the forestry is, and has been in focus for a longer period of time. Something that I saw as missing was an investigation of how much an active game keeping measure might cost in lost incomes for forestry in terms of reduced acreage for forest production. This question was the foundation for this investigation, which purpose is to give interested persons with decent knowledge of forestry an example of how cost estimation for forestry resembling the example that is studied can look like. The measures that has been taken is a felling of forest in different ages on both sides of a forest dirt road to create increased asset of forage for the game, and at the same time give hunters that have their post along the dirt road a better chance of seeing passing animals early and increasing the possibility to shoot good shots. The area, which is a part of The Swedish Association for Hunting and Wildlife Management estate Öster Malma, is also used as an example for guests who wish to learn more about managing ungulates. These guests have now got the opportunity to get information on how big the costs are for the measures that have been taken. The main conclusions of this work is that changed timber prices and foremost a change of interest rate makes big differences on the result of the calculations.

Objective: The objective is to examine if long terms of payment are created because of a perceived zero-sum game in the cash-to-cash cycles between companies. The study will also examine if dependence effects the dependent companies Cash-to-Cash-cycle because of long terms of payment. Scientific method: The study uses a qualitative and a quantitative method, where primary data is collected from semi-structured interviews. Additional primary data is collected from an unstructured interview with an expert in the field of which is examined. Additional data has been collected from the studied companies? annual reports.Theoretical references: The primary theory has been Game theory, where the researchers have used this theory to analyze the behaviors of the companies.

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

The purpose of this thesis is to evaluate three search engines with regard to retrieval effectiveness of information specific to Swedish users. Coverage and the precision in result descriptions are also examined. The three selected search engines are Google, MSN Search and Svesök. 30 queries were tested against the search engines and the first 20 result descriptions and results were judged for relevancy. Relevancy was judged by a binary scale.

The purpose of this thesis is to evaluate and compare the retrieval effectiveness of two search engines on the Internet: Svensk Medicin and Google Scholar. Svensk Medicin is a medicine-specific search engine and Google Scholar specialises in indexing scholarly material. A set of 20 questions in four categories were used to conduct the searches with the search engines. Genuine medical information needs were selected from a question collection provided by the television program Fråga doktorn. The relevance of the first 10 retrieved documents was judged by using a binary scale and the measure used was precision.

Within the literature and film sciences there are clear models of storytelling and methods of creating a good story. In the game industry it's more difficult because the games are often non-linear, and games are a less established medium than the other two. With this study our purpose was to examine game developers and methods they used when creating a videogame, with focus on storytelling. Four interviews were made with representatives from four different videogame companies in Sweden. The information from the interviews was put in relation to theories regarding the structure of videogames and an established model for creating videogames.

This paper examines possible applications of fuzzy logic on the field of artificial intelligence in digital games. It describes fuzzy logic in contrast to crisp logic. The paper will give several examples of possible applications of fuzzy logic-based decision making for game AI. These examples include the choosing of weapons for AI agents and the gas-break decision of an AI-controlled car. The paper will also analyze the impacts of game AI which makes decisions based on many factors.

Abstrakt I den här uppsatsen undersöks hur ett narrativ kan drivas inom digitala spel enbart med hjälp av spelmiljön. Syftet är att få förståelse för vad miljöberättande behärskar som en självständig form av berättande och vad författarna kan göra för att uppnå detta mål. För att undersöka problemområdet genomfördes en spelproduktion där metoder framtagna under undersökningens gång applicerades. Produktionen testades av utomstående studenter i medieteknik och resultaten sammanställdes med reflektioner kring vad som uppnåtts och de metoder som applicerats. Undersökningen beskriver arbetsprocessen och metoder och visar hur dessa kan driva ett narrativ med en spelmiljö. Abstract In this thesis examines how to drive a narrative in digital games using only the game environment.

Abstract ? Noblesse oblige: a roleplaying gameDuring the 17th-century the Swedish nobility was forced to deal with a number of new challenges. They reached the height of their power, but also began their downfall. How did the nobility?s ideal come to be in the face of this? Can we in these ideals find the duties and obligations of the nobility? And if we can, how can a roleplaying game be made out of the historical facts? A roleplaying game meant for educational means, well suited for the classroom and teachers, capable of stimulating the young minds and offering them an in depth understanding of how the nobility?s minds moved.
