Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

This thesis has been performed at BAE Systems Hägglunds, which is located in Örnsköldsvik. Hägglunds has a wide background of engineering, where they have manufactured all from airplanes to lifting cranes. Currently they only produce track vehicles at Hägglunds, where they manufacture the CV90 and BVS10 models. This thesis concerns the BVS10 which is an all-terrain-vehicle. The main purpose with the BVS10 is to enable transportation of material and personnel thru tough terrain.

The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.

The aim of this thesis is to mediate to the reader an image of Chinese classification systems and in what way the methods of classification have progressed during time. The tradition of classification in China is very old and dates back more than two thousand years, but it wasnt until the downfall of the dynastic era in the beginning of the 20th century, that Chinese libraries and methods of classification were modernized. This thesis also identifies the development of Chinese librarianship which is of old age since Chinese literature stretches three thousand years back. The main question is in what way the values of three different philosophies are reflected in five classification systems compiled between 1953-1975. The three philosophies are Daoism, Confucianism and Maoism/Mao Zedong Thought.

The purpose of this study is to examine how participants perceive virtual agents shown on a computer display. In particular, it is explored to what extent participants transfer gender and attraction stereotypes that are commonly applied in the physical world to virtual agents. Previous related studies have often explored only text or voice interfaces, without any visually appearing agents, and here indeed found evidence for a transfer of gender stereotypes. Our hypothesis was that the addition of a visual agent interface would reinforce this effect. The results support our hypothesis that participants transfer human gender and attraction stereotypes onto virtual agents, as well as that these processes are affected by the visual representations of the agents..

The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.

Vitamex AB är en nordisk egenvårdskoncern med huvudkontor i Norrköping som tillverkar och säljer naturläkemedel och kosttillskott. Inom Vitamex Production AB finns ett reklamationssystem för interna och externa reklamationer som hanteras pappersvägen. För att underlätta hanteringen önskade man ett webbaserat behörighetsstyrt datasystem. I det här examensarbetet beskrivs utvecklingen av ett webbaserat system där fokus har lagts på användbarhet. För utvecklingen har designteorin Usability Engineering använts.

This master thesis investigates how the county administrative boards communicate the regional risk and vulnerability analyses to municipalities in Sweden. Information has been gathered through a survey and through a case study involving three county administrative boards. The results revealed that there are possibilities to improve or develop the communication in all the county administrative boards. The information channels are often written or web based, these channels promote one way communication rather than a dialog. The thesis gives suggestion on how to work out a strategy for a more effective communication, the case study also gives ideas on how a county administrative board can work with communication..

Detta examensarbete ger en introduktion till Requirements Engineering (RE), kravprocessen i informationssystemutveckling. Det slutliga informationssystemet är i stor utsträckning beroende av en effektiv RE-process. Ett framgångsrikt informationssystem beror på hur väl det färdiga systemet stämmer överens med användarens och andra intressenters behov och förväntningar. Use Case är en teknik som kan användas i RE-processen för att representera krav. Arbetets syfte är att finna de för- och nackdelar som finns med Use Case för att representera krav.
