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.

In order to be able to change, to maintain competitiveness as a company in a world where rapid changes is part of the daily life, it is crucial to have knowledge and methods in how to change. One method, originally developed in Finland, is the Change Laboratory. This method is said to be efficient, not only concerning change aspects but also learning, since change and learning in this method is intertwined. This Master Thesis (20p.) tells about the process of conducting a Change Laboratory with a Swedish high-tech company and analyses factors in the process that makes change possible..

Introduction: Sleep disorders are an increasingly growing public health problem. InSweden, the last decade's increase in sleep problems was greatest among younger agegroups. Studies show association between the use of communication media and sleepinghabits. Objective: The aim is to map sleep habits and use of communication mediumamong adolescents and to study associations between them. Method: The study isbased on a previously collected survey data among high school students (18-21 years)from a coastal town in southern Sweden.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

This work is done to try to solve a scientific computer problem and its basis derived from the web, as there are a variety of ways to program to it. The most common languages used by developers, both private and corporate are PHP, .NET and Ruby. But why do companies or a private developer choose a specific programming language? Is it because it is better and has more features than the others, or because they are forced? This essay uses a questionnaire and through tests sees which is best and which one is the most popular/used. To illustrate the problem, a survey is conducted and sent to several companies and asked them to answer the questions regarding the issue.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.

The purpose of this study was to investigate pupils' and teachers' experiences of using the simulator computer game Minecraft in connection with the Swedish school competition Future City. The study examines how students (ages 14-15) and teachers have experienced the use of Minecraft, what the students have learned in relation to everyday education and the different forms of education during Future City and also examine which patterns that exists in the experiences of the students, with personal interest of and knowledge of Minecraft as a benchmark. The study was conducted through individual semi-structured interviews with both students and teachers. The analysis of the results is based upon a theoretical perspective that includes a socio-cultural view of learning, as well as the lines of reasoning in previous research about computer games and learning. As a general approach towards the study, and in a way, a justification of the chosen research method, a hermeneutic approach was used.

This report describes the work with creating a CMS (Content Manager System). A CMS is a web tool so you easy can publish materials on your web page. With a CM Scan you can without any knowledge of programming web pages create and maintain a web page. This will result in that you and your organisation save time and money. You can also split the responsibility for the webpage in different roles, but still keep the control. We have chosen to create our CMS in a script language called php4 and with the database server MySQL, we have also used JavaScript a lot.
