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.

Denna uppsats undersöker hur det fotografiska självporträttet används av ungdomar i tonåren och vilken betydelse det har i skapandet av den egna identiteten. Undersökningen besvarar frågeställningarna: På vilket sätt använder tonåringar den fotografiska bilden som redskap i sitt identitetsskapande? Hur kan fotografiet fungera som hjälpmedel för konstruktionen av självbilden? På vilket sätt väljer man att presentera bilden av sig själv? Hur kan man använda det jag sökande fotografiet i ett didaktiskt sammanhang och vad bör man vara uppmärksam på som pedagog? Insamling av empiriskt material till undersökningen har skett genom inhämtning av visuellt bildmaterial från en community på internet, via kvalitativa intervjuer med en grupp informanter samt via en litteraturstudie. Parallellt med det skrivna arbetet har jag genomfört en undersökande gestaltning på communityn bilddagboken.se. I gestaltningen har jag fotograferat mig själv kontinuerligt samt publicerat bilderna för att inta en betraktad-position.

This graduate thesis takes its hold in an idea that many values, in cultural heritage environments, other than the onesthat can be seen with the eyes are as important for the experience of the environment as the visual ones; however theenvironments are usually defined by values that can be experienced visually!Interviews were held with four visually impaired persons. This to get a better understanding for how big part othersense modalities play in the experience of the cultural heritage environments. Questions were asked about what thevisually impaired especially value in cultural heritage environments and what is of value for preservation. Also whatcan be done to make the environments more impressive for them, how they experience the material part of theheritage, architecture, shape and color and with what senses they primarily remember. Furthermore the thesis aims todraw attention to how value definitions made by the conservation field affects the experience of the environmentsand therefore the accessibility for visually impaired.

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.

The aim of this study was to increase our understanding of how secondary schools handle the different forms of bullying in different arenas. The questions we were asking us was how schools work to prevent and treat against bullying based on plans of action, how the schools are responsible in the bullying issues and how the schools and welfare officers have taken account of sex linkage in bullying issues. Our study is based on the result from seven qualitative semi- structured interviews with secondary school welfare officers in Sweden.  The study results show that traditional form of bullying takes place through verbal assault, physical violence, ostracism and glances. Welfare officers coincide that there are gender differences in the approach of bullying.

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.

Entreprenörer är viktiga för Sveriges ekonomiska tillväxt och företagens konkurrenskraft blir alltmer beroende av entreprenörens förmåga att tillgodogöra sig och använda sig av ny kunskap. Målet med denna studie var att undersöka hur entreprenörers erfarenhetsutbyte kan stödjas av IT. För att veta hur IT kan stödja erfarenhetsutbytet har entreprenörernas behov av erfarenhetsutbyte identifierats. Studien har visat att entreprenörernas erfarenhetsutbyte kan stödjas av en mängd olika IT-lösningar. Exempelvis skulle behovet av möten för att diskutera kunna tillgodoses av nätbaserade diskussionsforum, chatt och blogg.

The aim of this thesis has been to examine how the risk for the swine flu was represented in the Swedish Radio news broadcast Ekot 16.45 during different phases of the pandemic in 2009. We wanted to study how the risk was described in different discourses and periods? Were the participants in the reporting calming or warning the listeners in relations to different aspects of the swine flu? What consequences for the community were reported in the broadcasting?To find the answers to our questions, we analysed 13 features about the swine flu broadcasted in Ekot?s main news broadcast Ekot 16.45. We used critical discourse analysis inspired by Norman Fairclough.We identified four types of discourses in our text, a journalistic discourse, a medical discourse, a nationalistic discourse and an authority discourse. The main discourse was the medical one.

   Did the mass media report in a different way about the real estate tax before the Swedish national election 2006 than they did after the election? If there were differences, what could be the cause?This study aims to answer these questions by using a quantitative analysis of articles about the real estate tax published in the Dagens Nyheter (DN), the biggest morning daily. The summer before the election, the ?Alliance?, (the non-socialist coalition, launched an election promise to abolish the real estate tax. Instead they planned to introduce a low community charge.The Alliance won the election and formed a government to implement their election promise. The analysis was made on all the published articles in DN that covered the real estate tax issue. In total there were 43 such articles. These where all published between the launch of the campaign promise until the electionday and a month before the proposal was launched 19/9 2007, until the proposal was implemented in 2008. The study results in three interesting conclusions.

The Aquatic Ape theory was first formulated by Alister Hardy in year 1960. All from the beginning the theory has been criticized, ridiculed, ignored and a source to strong feelings in the anthropological community. The purpose of this essay is to investigate why the Aquatic Ape theory is so controversial and why it is understood so differently by scientists. After interviews with Swedish scientists and the general community, and after reading of anthropological books, I have tried to show that the aquatic ape-coldness depends on it challenging nature against the anthropological paradigm, which describes human beings as strong, hunting creatures who can live in any environment. The Aquatic Ape theory - on the other hand - picks out one of all these environments and says: "here has our evolution occurred: we have been aquatic apes".

The wide spread of the Internet and new information technologies in recent years has come to effect how libraries manage and disseminate information. Search engines like Google are widely used by people who often find the information retrieval systems of libraries to be too complicated. In 2004 Google announced plans to digitise five major library collections. Organisations representing the publishing industry and authors have since then filed lawsuits against Google claiming that Googles scanning of library books infringe the rights holders copyright. Due to Googles potential impact on libraries this thesis aims to examine how Googles digitisation project, Google Book Search, has been received in the library community.

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.
