This thesis contains a usability evaluation of ?Barnplay?, a Swedish video-on-demand service targeted at children. The objective of the study was to identify usability issues in the video service and to develop measures on improving the user interface, with special focus on adaptation to the broad target group of 3-11 year olds.The study was conducted by first mapping established practices in designs of VOD-services targeted at children, followed by interviews and usability tests with children between 2-11 concerning their use of ?Barnplay?. Based on the initial data collection, a prototype was developed and then evaluated by usability testing and A/B-testing.The main conclusion of the study is the need of better individual adjustment of the video content selection to better appeal to different age segments within the target group.

The purpose of this essey is through empirical methods investigate usability factors on Video On Demand applications for the Internet. More specificly we will focus on a application called Voddler. The purpose is to identify usability problems that exist in Voddler, and present the reader with suggestions on possible solutions. This could be used as guidelines to how to design for usability in this kind of system. We will use an online survey to investigate Voddler usability and use this data as a basis for our analysis.

Today's technology offers a variety of opportunities to interact with the interactive systems. Human-Computer Interaction in the last decade is the area of research that has contributed the most to this development. But how is this interaction perceived? The user experience is something that is formed by the interaction between human and the computer interactive systems. The objective of this thesis is to investigate how the user experience differs depending on how one interacts with a game.

Cleanboxen som den kallas är en flashbaserad2 produktpresentation. Simply Quality är ett företag som gör analyser och mäter renhet hos olika föremål på partikelnivå. Ett exempel på detta kan vara att ett företag som tillverkar bildelar skickar en del efter produktion för att få en analys på hur mycket partiklar/smuts som sitter kvar efter tillverkning. Vårt arbete var att ta fram en produktpresentation för deras mobila labb som säljs till företag som vill kunna göra sina analyser på plats. Behovet var att på något sätt kunna presentera Cleanboxen visuellt för sina kunder..

This bachelor´s thesis analyzes the debate in a number of Swedish media regarding the introduction of video games as a new medium in the public libraries. The theory and method used is discourse analysis. Three questions were asked: how the introduction of video games as a new media in libraries is discussed, how is it motivated and in what way the authors of the articles analyzed are speaking about new media and the mission of the library. The selected articles were divided into four themes and the analysis resulted in the identification of two main discourses, one which is positive to the introduction and integration of new media in the libraries? collections, and one which has a more negative approach and uses quality and culture as an argument. The conclusion is that video games are a medium so widely used that librarians have to decide whether or not they want to include it in the libraries? collections, and by deciding this they reveal their attitude towards the mission and purpose of the public library..

The gaming market has become the fastest growing market for leisure and is one of the most popular forms of homeentertainment. This has generated a media debate about how people are affected by gaming and concernes how we are affected by the violence that may occur in games. Games proponents argues that gaming is the future of teaching and computer games are becoming a sustainable and popular instruction strategy. Some studies have long used computer games for educational purposes. By interviewing high school students in focus groups as qualitative research, I studied their attitudes towards computer games as a learning tool.

Sweden. 1980. The term ?video violence? becomes public through the debates show Studio S. The show urges and obligates politicians to stop, regulate and ban video films with violent content from the market.

The aim of this study was to, through a qualitative method, investigate students? participation in a specific library blog to find out what motivate them to create and share digital book recommendations through videos. It also intended to describe the students? own views of their participation.We conducted interviews with eight students in the ages 12 and 13, who all had similar experiences regarding the blog creation but diverse attitudes concerning the blog production and intentions to participate.The results showed that the strongest motivating forces behind the students' participation in the blog creation was that they enjoyed the making of the videos and also because they wanted to inspire others to read more and create resembling blogs..

Active ownership is widely regarded as positive for the development and performance of businesses. In this paper, we investigate the impact of ownership concentration and owner identity on return on equity (ROE) in Swedish companies between 1986 and 2008, and show that active ownership might suffer from opposing effects. We find evidence, albeit weak, that ownership concentration has a positive effect on profitability, but that it levels off at high levels of ownership shares. Furthermore, we propose that family ownership has a negative effect on profitability. Our results are dependent of choice of statistical method, but show nonetheless a need to reevaluate what seems to be a universally positive view of active ownership..

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

Intention: The purpose of this thesis is to see if an active investment decision in the Swedish Premium Pension System would result in a higher return than a non-active investment decision. A non-active investment decision is equivalent to leaving the money in AP7 Premium Savings Fund.Method: This thesis is a statistical analysis and has a descriptive character in which the calculations are based on secondary data, thus the thesis has a quantitative character. Furthermore three active portfolios in different risk categories have been chosen. These portfolios are compared with the AP7 Premium Savings Fund?s returns.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Den viktigaste aspekten av human resource management kan i dagens samhälle anses vara rekryteringsprocessen. Syftet med denna kvalitativa studie var att fastställa om, och i så fall hur och till vilka tjänster, video bör användas som rekryteringsmetod. Detta för undersökandet av verktygets möjlighet att öka organisationers förutsättningar till konkurrenskraftigt övertag på arbetsmarknaden i enighet med Barneys teori om resource-based view. Analysen av resultatet utfördes utifrån tre teman ? fördelar och nackdelar med användandet, samt möjligheter till utveckling, av video som rekryteringsverktyg.

This essay covers computer gaming as seen from a perspective of gender theory. The main purpose of the essay is to examine women?s relationship to computer games, and more specifically women?s attitudes to the games they play. The theoretical basis for this essay is sprung from a hermeneutic perspective. The empirical basis for analysis consists of two in depth interviews and game analysis of the two computer games Counter Strike and Final Fantasy XI.

This thesis explores the possibilities of avoiding the issues generally associated with compression of noisy imagery, through the usage of vector quantization. By utilizing the learning aspects of vector quantization, image processing operations such as noise reduction could be implemented in a straightforward way. Several techniques are presented and evaluated. A direct comparison shows that for noisy imagery, vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding..
