Visualization is a rapidly growing area of computer graphics. Due to the very progressive development of computer technology and especially 3D-graphic boards yesterdays imagination of visualizations, today is a reality. At Saab Bofors Dynamics in Linköping missile systems are developed. Through the development, different subsystems are simulated before the manufacturing starts. The results of these simulations have to be visualized to get a meaning.

Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.

Normally the operational amplifier is used as a component in active filter design. The goal for future components in filter design is large bandwith and the use of low supply voltages. The use of current-mode instead of voltage-mode circuits gets a step closer to the required performance. A component that use current as the signal conveying part is the current conveyor. In this report a comparative study between two current conveyor structures of second generation (CCII) is performed.

This thesis is based on two different parts. First a presentation and a brief insight of the most comprehensive picture educational structures/theories and their various branches in Sweden from the post war period. Secondly a presentation of my artistic masters project Fantasy World, where I together with a group of children aged 7-12 freely created an artwork in the form of a world of its own, in sculptural expression. The idea behind the thesis has been to study how the perception of picture education and children?s creation has been in the recent decades and how different picture educational theories looks like and then to compare with the idea behind my project and how it may look in practice..

Authors: Philip Trollér & Jasmin FrljevicTitle: A sharp striker or forwardLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 62All throughout time the Swedish language has been influenced by various external languages. And throughout the years many loanwords have been introduced to the Swedish vocabulary. And this phenomenon occurs in the texts written by Swedish sport journalists. But in what extent do loanwords from the English vocabulary occur in texts written by Swedish sportjournalists, in what types of texts they can be found. And also why the usage of loanwords occur.The purpose of our study is to find out how frequent English loanwords are in Swedish sports journalism.

The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.

Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.

ABSTRACT?Crisis Management? New York Citys management of the terroristattack against World Trade Center?Essey in political science, C-level, at Karlstad University, by Sara Kringsberg.Spring 2006. Tutor: Susan MartonThe purpose of this essay is to study New York Citys management of a larger crisis and to see how states are coping with stress. It is important to study how states manage stress so that states can learn to cope with larger crisis. That is important for the survival of the state and the protection of its citizens.

The alpaca is a camelid that originate from the South American highland. During recent years it?s been possible to keep alpacas in other parts of the world. Today there is a world-wide interest in alpacas, but there is still limited knowledge about this fascinating animal. There are approximately 350-400 alpacas in Sweden in 2007.

In this master?s thesis the problem of simulating conditional Bernoulli distributed stochastic variables, given the sum, is considered. Three simulation methods are considered, namely the acceptance/rejection technique, Bondesson?s method and the Markov chain Monte Carlo method.To compare the three methods the bias and the standard deviations of the simulated variables are evaluated. The results of the simulation study shows that the Markov chain Monte Carlo method is not the best method for this type of simulation.

Syftet med arbetet är att undersöka hur möjligheter till flerstämmigt lärande såg ut i ett dataunderstött samarbetsprojekt World of Warcraft i årskurs 6. Frågan angrips med hjälp av metodtriangulering, vars huvuddel består av två lektionsobservationer, vilka förstärks med lärarintervjuer samt elevernas utvärderingar. Jag konkretiserar kartläggningen med produktioner som eleverna gjorde under projektets gång. Som en övergripande teoretisk ram för undersökningen används det sociokulturella perspektivet där relevanta aspekter belyses mer ingående ? flerstämmighet, livsvärldar, lärarens roll och lärande tillsammans.

This project practise methods used in the interaction design discipline to develop a concept related to the Swedish Guinness World Records Magazine. This project is a challenge to accommodate both the users? and client?s needs. We focus on interaction and the experience, which is acquired through the use itself, and how to connect it to a theme from a client. The aim of this project is to create a meeting place for children where they can interact with technology.

Det här arbetet behandlar frågan huruvida man kan använda etablerade studier av spelartyper och spelarbeteende av främst Bartle och Bateman, för att på ett praktiskt sätt hjälpa spelare att optimera sin spelupplevelse. Målet har varit att ta fram en metod för att hjälpa spelare att hitta den roll i onlinerollspelet World of Warcraft som passar spelarens spelartyp allra bäst och som denne har störst chans att uppskatta spelupplevelsen mest igenom.Detta har gjorts genom ett personlighetstest innehållande 21 frågor baserade på forskning av spelartyper och spelarbeteende. Utifrån testtagarens svar bedöms dennes spelartyp och den klass i World of Warcraft som bäst bedöms passa spelarens preferenser föreslås. Personlighetstestet har testats av en 15 personer stor testgrupp och resultaten visade på ett övervägande positivt mottagande och merparten var nöjda med den föreslagna klassen och tyckte spelartypsbeskrivningen passade dem.Utifrån resultaten av undersökningen dras slutsatser kring att det finns ett stort intresse för en personlighetstest av den typen, och att det har en stor potential att hjälpa både spelare att hitta sin roll i spelvärlden och för spelutvecklare att se vad som lockar i sin spelvärld och vilka spelartyper som de kanske bör satsa mer på att locka om de vill utvidga sin spelarbas..
