The purpose of this thesis is to evaluate 7 different search strategies for content-based image retrieval with respect to retrieval effectiveness. The strategies are based on different levels of resolution implemented by the Haar transformation. The result of the study shows an improvement in both mean average precision and mean recall in strategies based on lower levels of resolution..

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

Millions of people are using search engines every day when they are trying to find information on the Internet. The purpose of this report is to find out how people formulate search queries.

Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

After the fall of communism in Yugoslavia the ethnic resentment grew stronger and escalated in to interethnic civil conflict in 1992. After international intervention the General Framework Agreement for Peace (GFAP) installed peace in 1995. The treaty's aim was not only to establish peace but also to institute democracy in Bosnia. The OSCE were given the task to implement democracy within political institutions and civil society. This in a country with a lack of democratic experience and where great problems with ethnic antagonism still exists.By using democratization and transition theory this single case-study examines how democracy is implemented in Bosnia by the OSCE and clarifies difficulties that this democratization process is facing.

Syftet med denna studie är att undersöka vilken uppfattning elever i årskurs nio har om hälsa.

The ambition to use evidence based treatments has spread within the field of Swedish social work. The number of treatments with claim to being evidence based has grown but the research concerning implementation; the procedures being used to introduce new methods in organizations and assure that the method is being used appropriately and continuously, is scarce. The aim of this study was to examine the implementation of Functional Family Therapy (FFT), being an evidence based treatment, in an organization providing social services in the public sector, in Sweden. We used a qualitative research design and conducted interviews with persons involved in the implementation of FFT in the social services in a town in the south of Sweden. We used the practice guidelines provided in Evidence Based Practice (EBP) together with recently published meta- analyses of implementation research, in the field of social work, to examine the implementation of FFT, as being an evidence based treatment.

Bakgrund: Postpartumsamtal har minskat avsevärt visar studier genomförda i Sverige, trotsatt majoriteten av kvinnor önskar att samtala med den barnmorska som varit närvarande vidförlossningen. Ett viktigt mål för förlossningsvården är en positiv förlossningsupplevelse.Definition av begreppet samtal efter förlossning har ett flertal benämningar och tydligariktlinjer saknas gällande syfte, struktur, innehåll, målgrupp, samt när i tid och vem skall hållai samtalet. Syfte: Var att göra en sammanställning över publicerade studier där samtal omförlossningen förts med kvinnor som fött barn. Metod: En litteraturstudie baserad på 14vetenskapliga artiklar som identifierats efter sökning, huvudsakligen i databaserna PubMedoch Cinahl. Olika sökordskombinationer har använts då det inte finns något enhetligt begreppför samtal efter förlossning.

This paper examines possible applications of fuzzy logic on the field of artificial intelligence in digital games. It describes fuzzy logic in contrast to crisp logic. The paper will give several examples of possible applications of fuzzy logic-based decision making for game AI. These examples include the choosing of weapons for AI agents and the gas-break decision of an AI-controlled car. The paper will also analyze the impacts of game AI which makes decisions based on many factors.

Riskbruk av alkohol är ett stort problem i dagens samhälle. Sjuksköterskan beskrivs ha goda möjligheter att upptäcka och behandla riskbruk av alkohol i det dagliga arbetet. Studier tyder på att korta interventioner är av stor nytta till sjuksköterskan i sitt hälsofrämjande arbete. Dock visar forskningen att sjuksköterskans aktivitet inom detta område måste utvecklas och att det finns många faktorer som kan påverka uppgiften. Syftet med arbetet var att belysa faktorer som påverkar sjuksköterskans hälsofrämjande arbete gällande individer med ett riskbruk av alkohol.
