Open access has played a significant part in the development of scholarlycommunication. Today, several research funding agencies around the worldrequires that the results of the research it supports must be published openaccess where the underlying idea is that publicly funded research should befree and available to all users. The purpose of this thesis is to discuss the issueof open access publishing from the perspective of researchers in the field ofodontology, focused on their attitudes, behaviors and publishing experienceswith open access. Through a qualitative interview study with fiveodontological researchers, the results have been compared to previous studieson researchers' attitudes and experiences with open access. The results showthat both knowledge and experience with open access publishing is fairly lowamong the participating scientists.

Open source software has recently been discussed, not least in media as a revolution in IT. A number of advantages have been listed in changing proprietary software into open source software. Examples of such pros are no expenses for license fees and improved efficiency. In spite of this, few users have made this change. One of the reasons is a distrust of the quality in open source software.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

The aim of this study has been to examine what students within the sport of skydiving think about their education and the social spirit of the community. The purpose of the study is thereby to answer the study's aim through the following questions; how does group dynamics and social solidarity work within the skydiving community, how do the students feel about group dynamics and social solidarity within the skydiving community, and what factors makes the students feel included or respectively excluded from the spirit of the togetherness?The theoretical part of the study focuses on group dynamics and groups overall. Further on earlier research within adventure sports and skydiving regarding group dynamics and community spirit is presented. My survey is based on 35 interviews with skydiving students.The result shows that the community spirit within skydiving sports is described by the students as very special, unique, and strong among the members.

This report describes an analysis of WebGL together with JavaScript with the aim to examine its limitations, strengths and weaknesses. This analysis was performed by building a 2D game engine containing some dynamic elements such as water, smoke, fire, light, and more. Different algorithms have been tested and analyzed to provide a clearer picture of how these work together. The report will go through the most basic functions of the game engine and describe briefly how these work.The result shows that JavaScript with WebGL can be considered to be a potent toolsets, despite the difficulties caused by JavaScript.In summary, similar projects can be recommended as Javascript and WebGL proved both fun and incredibly rewarding to work with..

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Allteftersom 3d-animerade produktioner blir alltmer vanliga både i film och i TV-produktioner och datorer blir kraftfullare varje år: så börjar realtidsrendering bli mer och mer aktuellt. I detta examensarbete kommer jag främst att koncentrera mig på att skapa koncept, modellering, texturering, behandling av material och ljussättning av en prototypkaraktär där målet är att se om det går att uppnå en så pass hög kvalité på det visuella, att det går att använda i en professionell produktion och om detta inte uppnås: ta reda på vad som saknas. Resultatet är en karaktärsmodell med en tecknad visuell stil med tillhörande återanvändbart material, som förhoppningsvis ser tillräckligt bra ut för att kunna användas i till exempel ett animerat barnprogram på TV.

Sun Microsystems chose its own Open Source path by not following competitors in their commitment toGNU/Linux. Sun instead created its own Open Source project from the source of Solaris under the name ofOpenSolaris. The business model of OpenSolaris belongs to the new and more commercially viable OpenSource, referred to as OSSg2. This survey was based on articles on the adoption of Open Source in organizationsand István Orci?s publication Kritiska IT-System.

Applications for mobile devices, also known as apps, are today the backbone of a huge market where the company Apple is one of the key players. Apple develops, among other things, handheld electronic devices, which are powered by the operating system iOS. Through iOS, millions of customers get access to Apple?s App Store.During a period of two months, an app in the form of a game has been developed for iOS in the programming language Objective-C. The user of the app is presented intuitive menus and interactive graphical objects that seemingly obey physical laws.

The purpose with this thesis is to get a compilation of all the critical bolted joints of all enginesproduced at LV Motors. ABB LV Motors produces induction engines with seven shaft heights. Eachengine size exists several variants of components ex. standard shield and flange shield. Depending onwhich components the engine is equipped with arises various types of strains in the engine's parts,certain assembly ways are more favourable than other.The most critical parts in the engine from a mechanical point of view are the screw units betweenshield/stator, feet/stator and bearing cover/shield.

Open source is growing outside the boundaries of hackers, amateurs and software development, creating a humongous potential in many different areas and aspects of society. The intrinsic and extrinsic motivations that drives open source have been in the subject of much research recently, but how they affect each other when paid and unpaid contributors come together is still hidden in obscurity. In this study I investigate how intrinsic and extrinsic motivation correlates with each other and how those correlations affect paid and unpaid open source software contributors. The literature synthesis is based on of systematic reviews through searches in library databases, identification of articles by searching on the Internet and by reading relevant books. My results indicate that intrinsic and extrinsic motivations continuously affect each other and that paid contributors are more vulnerable since their extrinsic motivation in terms of money is reached only when many other motivations are fulfilled.
