Biologisk mångfald och skogsproduktion : -en målkonflikt i skogen?
The purpose of this work, has been to examine how different actors in the Swedish eco movement and the Swedish forest industry looks at Sweden?s forest policy statement, which claims that environmental goals and production goals should be equal in Swedish forestry. By assembling focusgroups with participants from the Swedish eco movement and the Swedish forest industry, we look at if these participants consider the Swedish forest policy goals equal or not. Conflicts do occur between the two forest policy goals, but also between those and others of Sweden?s environmental goals.
Analys av systemfaktorers påverkan på tillförlitligheten i distributionsnät
In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.
Vision Enhancement System : Vilken betydelse har displayplaceringen?
At night, the visibility is reduced and the demands on the driver increase. A safety system that enables the driver to discover warmer objects in the surroundings when the visibility are reduced, such as the Vision Enhancement System (VES) contributes to safer night-time driving. Since the benefits of this system are established, it is of interest to investigate different design aspects. The VES display has in earlier studies been positioned in front of the driver but different display positions such as peripheral placement should be evaluated. The present simulator study is an investigation of the effects of different display positions inside the car.

Inledning till spelutveckling för AndroidSpelutveckling för Android med Java och OpenGL ES
This thesis deals with the problems you face as a new game developer for the mobile platform Android when developing a 3D game and presents solutions to these problems. It also explores which optimizations should be made to increase performance and how well suited for game development the Android platform is. A simple 3D game for version 2.2 of Android was developed to examine this. The conclusion was that a good game structure for Android separates logic and rendering by running these separately in different threads. Solutions to rendering and updating of game logic were presented and optimizations were implemented for performance, although fewer optimizations were needed than was anticipated.
