Då artificiella intelligenta agenter försöker navigera i en virtuell värld med statiska hinder så behöver dess väg beräknas. För denna beräkning används ett lager som beskriver hur och vart agenten kan röra sig i världen kallat för sökrymd. Detta kan göras på flera olika sätt vilket ger skillnad i prestanda och minnesåtgång samt indirekta fördelar genom sättet sökrymden är uppbyggd på. Genom att jämföra dessa skillnader i olika miljöer så kan resultatet påvisa vilka egenskaper sökrymdstyperna ger i de olika miljöerna.Rapporten visar att n-sidat polygonbaserat navigationsnät ger mycket bra egenskaper i de olika mätningarna och ger även flera fördelar på grund av dess utformning som gör att det kan anpassa sig bra till olika miljöer..

This project report shows the work around a mockup to a three-dimensional avatar-making application. An avatar-making application is a computer-based software program in which it is possible to create your own personal virtual character. The possibility to use three-dimensional avatars can in the future be essential for adding extra personal information or characteristics to social communication over the internet or over mobile phones. The problem of transforming a physical form and reconstruct it to a virtual basis has been an important problem to solve for many companies and software developers in the, for instance, virtual worlds area. Methods and ideas over making this transformation is the key throughout this project.

The idea for the thesis ?Construction and implementation of a mobile prototype; The Lovebomb? originates from doctoral candidates Rebecca Hansson and Tobias Skog from PLAY Research Group at the Interactive Institute in Gothenburg. The object of the master thesis is to construct two working LoveBomb prototypes, one mother console belonging to the LoveBomb and blueprints for both. The LoveBomb (the picture to the right shows a possible design) is intended to encourage people to express themselves emotionally when situated amongst strangers in public spaces. Two buttons control the device, which contains a radio transceiver.

Modern air battles are very dynamic and fast, and put extreme pressure on pilots. In some unpredictable situations, like new discovered threats or mission plan deviation because of enemy aircraft, the pilots might need to replan their predefined flight route. This is very difficult, if not impossible, to do since numerous factors affect it. A system that can help the pilots to do such a thing is needed. Previous work in this field has involved methods from artificial intelligence like A*-search.

The CASA-paradigm, Computers Are Social Actors, was introduced in the book "TheMedia Equation" by Reeves and Nass. One of their experiments concluded that we tend to be polite to computers in the same way as we are to people. In this study I have replicated Reeves and Nass experiment but instead of a text-based interface I have used a virtual agentin order to find out if we are polite to the agents, or still to the computer. Two experimental setups was conducted. The two setups had a common first part that was carried out on onecomputer with one agent.

The interest in businesses active on the countryside and their funding situation has increased in recent years. In a survey, conducted by Leif Berndtsson (2003), it was reported that there is a lack of external capital in rural areas. According to Berndtsson (2003) the lack of external capital inhibits the rural firm?s growth. The essay attempts to answer whether the shortage of external capital is a factor that inhibits development for rural businesses.

SecRePac is a household appliance that simplifies sorting of packaging such as milk, juice and yogurt containers. By shredding the packages SecRePac reduces its volume uptake both in the home and at the recycling station. This leads to minimization of both transports to the recycling stations and truck transport for emptying the containers at the recycling station.The greenhouse effect deteriorates and becomes worse and worse leading to extreme climate changes and natural disasters such as floods as an example. Carbon dioxide emissions are the major reason for this and at least 30 percent of all these emissions come directly from transports. In the EU carbon emissions has decreased in the past few years.

The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. As a sustainable control method, pheromones have been successfully applied to disrupt moth mating behaviour. Other behaviours like foraging, search for mating sites or host finding could be potential targets for additional odour-mediated behavioural manipulation but need further investigations of the underlying odour stimuli and behavioural plasticity. Many insects are attracted to the smell of fermenting fruit and associated microorganisms.

This Master?s thesis investigates user education at high school libraries. The aim of this study is to examine user education and the educational approach that librarian?s experience in their teaching. The method used for the study is qualitative interviews with seven high school librarians.

Background: Traditional oral health education is seldom enough in order for dental care personnel to motivate their patients to good, long-lasting oral health care habits and there is a need for evaluation of other more efficient methods. One of these methods is motivational interviewing. An overview of its origin, definition, theoretical background and practical methods is given by way of introduction. Aim: The aim of the investigation was to review studies that had used motivational interviewing in order to obtain oral health, focusing on prevention and treatment of gingivitis, periodontitis and dental caries. Method: Systematic review. A search question was run through the databases ASSIA, ERIC, PsycINFO, Social Services Abstracts, Sociological Abstracts and PubMed. The articles were reviewed based on defined inclusion and exclusion criteria. Results: Five publications (based on three studies) met the inclusion criteria.

The purpose of this legal dogmatic Bachelor Thesis is to define the legal definition of ?a rescue service? and illustrate the division of responsibilities between national authorities and the municipalities with regards to the execution of emergency response operations.?A rescue service? means the emergency response actions that national and municipal authorities are legally obliged to provide to prevent or minimise injury to people and damage to property or the environment when emergencies occur or seem imminent. In the following cases a national authority is responsible for providing the requisite rescue service:1. Search and rescue (air) ? the Swedish Civil Aviation Authority is the responsible authority;2.

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

This Master?s thesis is the first to quantitatively study the prevalence of library anxiety at a Swedish university. Library anxiety is a concept describing the negative feelings students can experience when using the library. The study was conducted using web questionnaires sent out to 512 students at Växjö university. 38 % responded and the results were analysed with the help of, amongst other methods, correlation studies.

Målet med uppsatsen är att åskådliggöra vilka fördelar, nackdelar och effekter användarbaserad systemutveckling har för den administrativa delen av en organisation. Intervjuer har gjorts med en chef och en controller på ett större svenskt företag samt med en expert inom området för användarbaserad systemutveckling. Undersökningen visar att fördelar som ges vid användande av användarbaserad systemutveckling är t.ex. att organisationen och individen blir mer produktiv, får en mer flexibel miljö att arbeta med och blir mindre beroende av konsulter. Nackdelar har visat sig vara att organisationen kan försätta sig i en situation där de blir beroende av den person som har utvecklat ett specifikt system och kvaliteten på underhåll kan även försämras när användarna utvecklar själva.

I have together with Frimeko AB developed new hallway furniture for preschools. The background to the project is the fact that all the existing hallway furniture?s on the market today have a similar design and same features. None of the furniture stands out immediately. Companies who work with school furniture in general have been inspired by each other, and therefore is the collections monotonous.
