The purpose of this article is to investigate how and from which sources librarians collect information on their profession with respect to factors that are important for their work. In order to achieve this goal, a questionnaire-based survey will be conducted at three medium-sized central-public-libraries in southern Sweden. Using this survey, I wish to answer the following four questions: To what extent do librarians acquaint themselves with changes and developments within regional and cultural policy arenas important to their work? To what extent do librarians acquaint themselves with information using conferences and library debates that are focussed on changes and developments relevant to their work? Do librarians consider that they have enough time within the limits of their work hours to follow developments within the librarian profession, for example with respect to developments within information technology, and how would they appraise the future demand for information technology-based services at the library? From which source(s) do librarians collect information relevant to their work? The theoretical basis of this paper can be compared to a radar as it scans subjects-of-interest to the organization in the field of business intelligence. This investigation uses a quantitative method, with data collected via a survey consisting of 13 questions.

Design principles are usually used by interaction designers to help creating a user friendly design by making the designer think about the different aspects of the design. These design principles has been further developed since they emerged in the 1990s, and today they're often used in the field of interaction design. By using the design principles, bad design can be avoided and the frustration of the user reduced. Design patterns is described as structural and behavioral characteristics to improve the environment in user interface amongst other areas. These characteristics could make things easier to understand or improve their appearance, they make tools more usable.The purpose with this essay is to identify design guidelinesto be used by developers when designing surveillance systems.

Kamouflage är ett viktigt område inom militär överlevnadsstrategi. Ur ett taktiskt perspektiv innebär kamouflage att anpassa rörelse, uppträdande och placering efter aktuell miljö och situation. Ur ett tekniskt perspektiv innebär kamouflage att kontrasten för ett objekt minskas mot dess omgivning. Detta gäller för hela det elektromagnetiska spektrumet där hotbilden ges av varierande sensorer i radar- och IR-området såväl som i det visuella området. I takt med att tekniken går framåt utvecklas mer avancerade sensorer.

Uppgiften har inneburit att utreda och redovisa några av de möjliga sensoralternativ som med ett 10-årigt perspektiv är möjliga att implementera i en svensk UAV motsvarande det svenska UAV - systemet ?Ugglan?. Fokus avseende uppgifter för UAV ? systemet har legat på taktisk nivå med inriktning mot spaning och ledning av indirekt eld. Slutligen har uppgiften varit att värdera de olika sensoralternativen och förorda vilken eller vilka sensorer i kombination som ger bäst effekt sett till tänkt användningsområde för UAV´n.

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

På Robotförsöksplats Norrland, RFN, i Vidsel, har flygplan och robotar utprovats sedan 1958. Provplatsen har Västeuropas största provområde över land, med en area på över 1600 kvadratkilometer. Radar, Kinoteodoliter, Telemetri och Kameror används för att övervaka provobjektens rörelser. Att kunna följa robotbanan och lagra positionsdata är en väsentlig del av provningsverksamheten.All positionsdata samlas in av ledningsprogramvaran, BAPS, och används för att i realtid presentera positionsdata på en karta till stöd för provledaren. Samma data kan sedan bearbetas för att generera mera exakta positionsuppgifter i efterhand.2001 infördes ett nytt geodetiskt referenssystem i Sverige, SWEREF99.
