I Södermanland visade sig att brukare var mest tillfredsställda med variabelnanvändbarhet..

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

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.

Electromyography (EMG) is a technique that measures muscle activity, whichmeans detecting the electrical signals that travel through the muscle in connectionwith muscle contraction. This project deals with how EMG can be used tocontrol a computer game.The project is centered around the game 'EMG Track Game' which has beenconstructed as part of this work. 'EMG Track Game' is controlled by twoelectrodes fastened on the player. These are attached to two selected musclesand control the motion in one direction each, one up and the other one down.The game is constructed in the purpose of being used in several elds of application.Among these are as entertainment, training equipment and a tool inresearch related to EMG and muscles.To highlight a possible application a study concerning muscle control has beenconducted. It answers the question of whether players score better with theirdominant arm in comparison with their non-dominant one.

The purpose of this essey is through empirical methods investigate usability factors on Video On Demand applications for the Internet. More specificly we will focus on a application called Voddler. The purpose is to identify usability problems that exist in Voddler, and present the reader with suggestions on possible solutions. This could be used as guidelines to how to design for usability in this kind of system. We will use an online survey to investigate Voddler usability and use this data as a basis for our analysis.

The Trappan Model is one of the most implemented treatment programs for children who have experienced domestic violence. This study undertakes a wider evaluation of the model through a pilot study. The approach is both quantitive and qualitative. Theory as well as the Strengths and Difficulties Questionnaire have been used to fulfil the aim. The design is pre-post.

This is a thesis on the Intranet use in the European Parliament. We investigated the use from a multilingual point of view, but also from a communication perspective. What we wanted to know was how a multilingual group, with presumably different computer skills, in the organisation handle the Intranet information. What are the positive and negative effects of a multilingual information exchange over an Intranet? To find out, we sent a questionnaire as an e-mail attachment to all members of a chosen committee and their assistants.

The present Equality Project in the Swedish preschool has been studied according to its view on sex and equality. The purpose was to find out how the Equality Project is described, interpreted and implemented.The research questions focused the central concepts sex (gender identity, gender roles and gender patterns) and equality in the political level, the educational level and the executing level of the Equality Project. From each level some central texts were chosen and analysed.The results indicated that equality is interpreted as connected to an absence of gender patterns and gender roles. The concept of gender identity is differently understood in the different texts. The normative focus and the lack of psychology in the Equality Project are discussed..

The intention is to focus on the implementation of the tablet in preschools and how the intentions around the introduction of the tablet take shape in different preschools. The method is semi structured interviews where the respondents consist of 3 preschool directors and 6 teachers where the preschool directors work. This is a relevant subject to illustrate, as the tablet has become a tool in preschool where it seems to be different opinions about how it should be used. This study aims to understand how the implementation can take form in different preschools, what kind of similarities and differences we can see with the intentions of the tablet and if there is need of clarification on the workings of the tablets in preschools. The results show that the intentions around the introduction of the tablet in preschool look different in the preschools, and the implementation of this new technology starts in a small scale with help of photographing and videotaping.

Eco certification of small housesTo construct an environmental friendly building and show that as a company you care for the environment, is presently very attractive in the Swedish real estate market.This degree thesis covers the environmental certification called ?Svanenmärkning? the Swan, witch is the Swedish equivalent to the European standard ?the EU Flower?. It is concentrated on the certification process in small houses that the Swedish institute of standard, SIS, has presented. We have worked together with the company Faluhus witch is a Swedish producer of small family houses.Faluhus is located in the town of Borlänge, Dalarna and has produced family houses since the 1950:s. They have a great heritage born in the old Swedish mining culture, with great wooden mansions and country homes.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to networks the size of the Internet.
