H2 För racing
AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.
Informationssökning för barn och ungdomar politiska dokument och konkret verksamhet

Intranät från ett användarperspektiv: En fallstudie om hur en grupp bibliotekarier upplever och använder sig av intranät i deras yrkesroll.
This is an investigation into the ways in which a group of librarians experience and make use of the intranet in their vocational role. The theoretical frame of reference consists of a model of how professionals seek information, which is based on a role-theory. As a method, I have applied a qualitative case-study. Using semi-structured qualitative interviews I have interviewed five librarians and the webmaster responsible for the intranet in their library. I have investigated how elements such as the age and vocational role of the librarians affect their use of the intranet.
Den slutna cirkeln, eller varför mångfalden inte når till toppen
Sweden is usually seen as a role model when it comes to integration and diversity, but at the top of the pyramid there is little ethnical diversity to be found. This paper investigates how existing economical and sociological theory explain the lack of swedes with foreign background in leading positions in large Swedish companies. Our findings show that none of the theories applied in this paper can explain the phenomenon in isolation. Thus it is not only taken for granted norms, contacts in one's network or cost minimizing under asymmetric information that lie behind the phenomenon, but an interaction of these aspects. Conflicting demands lead the recruiters to separate talk from decision, the search frame is narrow and no or small efforts are made to increase the diversity.
Webbplatsen EUROPA: en utvärdering av söktjänsten
The purpose of this thesis is to evaluate the retrieval effectiveness on the European Unions official website EUROPA, depending on which language is used to formulate the search question. Our main concern were if you get access to the same information depending on which language is used to search information The European Union has so far eleven official languages, and with the forthcoming expansion with negotiations with thirteen new countries to affiliate to the union by May 1:st 2004, the official languages will be even more. We have made a comparison between Swedish and English, using 29 different topics from which we formulated 2x29 queries. The topics used were found at the Swedish Governments FAQ about the European Union, EUsvar. We wanted the topics to be as authentic as possible to avoid bias.

Heuristisk detektering av trojaner
The heuristic methods used by the anti-trojan application TrojanHunter have been evaluated. The evaluation shows that the heuristic scan engine of TrojanHunter has a very good detection ratio and that the detection ratio can be even further improved by implementing the suggested improvements, the most important of which is a white list to avoid misidentifying files that are known not to be trojans..
Aktiv ventilstyrning
To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.
Att finna bilden - varför indexera bilder efter innehåll och hur bedömer man en bild?
Computerized methods for searching pictures are becoming more common. With these it ispossible to make powerful search requests using a combination of terms and search oncomprehensive descriptions of the pictures. The descriptions can encompass various aspectsof the content and allow different interpretations and levels of detail.This essay is about how you can examine and describe the content of a picture from manypoints of view. We have tried to identify differences in searching behaviour, and studiedsome methods for indexing of pictures. Our concepts are taken from the philosophy of artand from theories about the meaning of languages.In the future perhaps libraries can make pictures and illustrations in books available to thepublic, in a sophisticated system, for the purpose of providing visual documentation forstudy, research or other kinds of exploitation..

Barnanpassade söktjänster på Internet
The purpose of this study is to investigate childrens possibilities to retrieve information by searching in searching engines designed for children. Two such Search engines are examined: Yahooligans and Kids Click, both of which index pages in English only. I have compared Yahooligans with its equivalence for adults; Yahoo, by evaluating the retrieval effectiveness. Some functions in Kids Click and in Yahooligan are investigated. Seven class room studies are described in the prior research chapter.
Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem
The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.
