This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

This is a qualitative study that explores how bilingual children develop their language through play. The study is based on observations and interviews conducted in a preschool located in a multicultural area of Stockholm.The purpose of using two qualitative methods; observations and interviews, was to get a bigger picture of the study area. The results of the study, illustrated through observations and interviews that I have conducted, shows that the game has great role for bilingual children's language development. Furthermore, the results show that the informants are aware of the importance of play for bilingual children's language development especially when they are talking about investing in the promotion of children's language by using different methods and materials in their pre activity for various games and activities.One of my conclusions is that bilingual children learn the language during both free play and structured play especially when educators are present and aware of the activities that they perform. It is also important to see children as individuals to cover all the needs of children at different activities.

This report reflects an examination work performed for Getrag All Wheel Drive AB during the spring of 2005. Among the companies range of products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque.The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for clamping force and friction through utilization of existing testing equipment.Three separate methods of clamping force and friction determination have been tested in rear drive unit, RDU, at a 30 Nm assembly torque. A fourth and final method, screw elongation with ultrasound, has been used as reference. The methods are:?Torque-Tension test.?Screw elongation with micrometer.?Joint stiffness test.?Screw elongation with ultra sound for reference.The results from tests can be viewed in table below.MethodTorque-TensionMicrometerCs=318 kN/mm Assembled with torque wrenchMicrometerCs=318 kN/mm Assembled on lineUltra-soundCS=311 kN/mm Ultra- soundCS=318 kN/mm Joint stiffnessTheoreticalClamping force-21,8 kN17,6 kN17,3 kN17,6 kN17,1 kN17,3 kNFriction-0,110,1470,1530,1470,1520,149.

American football is a well-known sport in America. In addition to the design and rules of the game and the surface it is played on, there are also other differences that are not directly visible. One difference noted in this study is how the teams in the game provide players. Each team has a board of directors together with the team's leadership and they will determine which players are most suitable for the team. These players are recruited to the team after graduating from a U.S.

This report is a documentation of the workflow and the result of a project carried out by twostudents from the Royal Institute of Technology in collaboration with a company. The report isstructured in a chronological order and describes the methods and systems developed in theworkflow. The report shows how the project evolved from a study phase to the various proposals onthe concept solutions.The project aims to develop a systematic way of bonding two different kind of cardboard under fiveminutes. By conducting a general study about glue and its different forms it was possible to obtain abroad knowledge, which helped to choose the right substances to later use in testing on the differentcardboard materials in question. Glues's survey resulted in a list of different substances that wererelevant to the project.

This essay covers computer gaming as seen from a perspective of gender theory. The main purpose of the essay is to examine women?s relationship to computer games, and more specifically women?s attitudes to the games they play. The theoretical basis for this essay is sprung from a hermeneutic perspective. The empirical basis for analysis consists of two in depth interviews and game analysis of the two computer games Counter Strike and Final Fantasy XI.

Tobii Technology AB is a global leading company in eye tracking. The technology is a part of acomputer screen called an eye tracker. It enables computers to follow eye movement whichfurther make it possible to control the computer by only using your eyes.The mission was to develop an arcade game for eye controlled games that Tobii can use in theirmarketing or as a tool when doing researches about the interest in the technology amongst gamecompanies. The product realization involved designing an innovative, functional and futuristiccase which gathered the existing hardware and software to build the final prototype. In order toattract users it was important to focus on the visual expressions.Initially, the project started off with an information retrieval which contained interviews, fieldstudies, tests and literature studies.

The purpose of this paper is to investigate how gender and sexuality are made in the videogames Prince of Persia and Fable II, and more specifically to look at possibilities and limitations for the construction of gender and sexuality in these games. I understand videogames as an interactive media form that differs from other types of media like film and literature. It is a media form that depends on a player to be played. At the same time it is constituted by rules of how it can be played. I have analyzed my material by a method called close-playing.

SVENSKA: Vårt kandidatarbete gick ut på att ta reda på om det var möjligt att utveckla ett kort spel i hög teknisk kvalitet och ändå skapa ett djupt intryck på spelaren. Under projektets gång utvecklade vi, med hjälp av UDK (Unreal Development Kit), ett skräckspel i 3D till PC vid namn The Horror at MS Aurora. För att erhålla den höga tekniska kvaliteten som vi var ute efter användes metoder som räknas som standard för stora speltitlar på marknaden: Animationer spelades in med Motion Capture och musiken skrevs med en full symfoniorkester i åtanke. Innan produktionsfasen tog vid gick alla gruppmedlemmarna igenom en research-fas, där var och en satte sig in i de områden som skulle komma att vara aktuella under produktionen (d.v.s. hur UDK fungerar, musikteori och orkestrationsteknik, hur man arbetar med Motion Capture-data o.s.v.).

The purpose of this bachelor?s thesis is to examine video games, gamers and gaming from an information science perspective. The purpose of the study is partly to study video games as a type of information system and partly to study gamers information use, information seeking and also the experience of gaming. A selection of five games have been analysed using a topology for video game analysis created by Espen Aarseth. A quantitative investigation has also been made, in the form of a web survey distributed through four Swedish online forums, the result of which was analysed using Carol Collier Kuhlthaus model of the information seeking process.

This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

This thesis aims to research how megacorporations are depicted in popular media by analyzing the video game Cyberpunk 2077. In this assignment I focus on how the narrative of said game discusses economic globalization, megacorporations specifically which is accomplished using a set of theories such as: exploitation, commodification and capitalist realism. The analysis is constituted using a modified version of narrative analysis in order to better suit my research field as well as presenting a clear and concise structure a reader can follow. This study concludes that Cyberpunk 2077 constructs a dystopian world with the megacorporations holding the political power where the majority is constantly oppressed by the 1% in power. Things that we find human are questioned and diminished in order to increase the profits of those in power which tends to be the megacorporations.

There is a strong debate in the media about the CEO compensation in the listed companies and whether they deserve their high rewards. Many previous studies have shown differences in the reward system depending on the ownership structure, mostly testing for only ownership concentration or ownership category. This study aims to investigate how the influence of the owners affects the CEO reward system, testing for both the level and the structure of the reward. The sample used in the investigation is Swedish listed corporations and consists of 251 observations. A survey was also conducted but due to low response rate and because the answers are not representative for the whole sample the survey will only be used as an illustration.
