In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

The purpose of this thesis is to investigate how Digital Signage systems such as public info kiosks can be designed to better fulfill its main use; to enlighten, encourage and influence the public with information. The challenges presented from earlier studies shows that the public interests and goals, together with proper and relevant content displayed in info kiosks have impact on the attention the public have towards public displays. Qualitative methods such as interviews, usability testing and observations were conducted to further examine how a public info kiosk can be designed to draw attention and grow interest amongst students at K3, Malmo University. Usability testing were used on the digital prototypes that were developed to ensure that the gestural user interface meet the requirements of a proper interaction from the users. Important insights were made concerning; the attention and interest to relevant content, the aspects of the gestural user interface along with the placement of the info kiosk in terms of context.

Collaborative music making on the Internet is not a new phenomenon, but no applications have yet caught on with the vast number of laptop and bedroom studio musicians active today. This is strange considering the inherent social and interactive nature of music, especially amongst trends like Web 2.0 where collaboration and user-generated data is key. In this paper I study the problems these applications face, and why they do not have a greater appeal to musicians. With the results I develop and evaluate my own framework, known as Crescendo Online: a multi-user sequencing and modular synthesis environment, intended to pave the way for a new type of online music creation platform..

In this paper we explore the relations between context and feedback generated in three user-centered evaluations of a flash-based game. Whether it?s the social context, the physical context or the degree of intrusion from the evaluator, they all contribute to the quality of the feedback received. The selection of test subjects is a narrow process, which gives the above mentioned factors different meaning. Contextual factors have shown to influence the feedback given within both usability and user-experience.

The purpose of this study is to investigate the effectiveness of consumer generated advertising as a marketing tool to encourage online word of mouth. Subsequently, the researchers aim to examine if there are certain design factors in consumer generated advertising that influence the effectiveness of consumer generated advertising in encouraging online word of mouth. The study conducts a multiple case study of several consumer generated advertising campaigns. It consists of in-depth studies of these cases in combination with quantitative analyses of the encouraged word of mouth. The different cases are examined on several design factors that could possible increase the volume of encouraged word of mouth..

The aim of this master thesis is to study how academic librarians can overcome the gap between themselves and the user. The gap, as we see it, is generated by the user's deeper knowledge surrounding her subject in comparison to the librarian. This knowledge gives the user possibilities to handle certain discourses attached to the subject and a knowledge how sub-subjects relate to each other within the main subject. At the same time the user is in need of help to find information within her subject, this need needs to be explained to the librarian as a search expert. The scope of this master thesis is to find how the librarian, tactically, can reach the users need despite lack of subject knowledge.

Journalists´ role in society has traditionally been of representative nature with a task to distribute news and scrutinize those in power. But technological changes have created a new publishing world outside the traditional media institutions. In today?s redactional society anyone can become a publisher in a blog or through other channels on online. This process can be seen as contributing to increased democratization giving everyone the opportunity to publish.

This essay is an investigation of the level- and importance of interactivity on YouTube for the active user. YouTube is a great example of a user-friendly Internet environment which enables the users to take part in a virtual community where they can create the content and, with the various functions the site has to offer, interact with each other. With Uses and Gratifications as a tool for this research we look at the motivations and needs of the user and how they come into play on the most popular video distribution site in the world today. Qualitative interviews on Swedish respondents give us insight in how the YouTube-users with their own words perceive this relatively new highly interactive era. We focus on a narrow group of the most popular age-group of YouTube-users to go deeper - not to expand.

Användarskapat innehåll, eller UGC från engelskans User Generated Content, har med teknikens utveckling blivit allt mer populärt på webbtidningar. Det ses som en konkurrensfördel men kan även innebära risker för tidningen, inte minst kostnadsmässigt. Det blir därför viktigt att satsa på UGC som läsarna vill ha, men vad detta innebär är inte ett välutforskat ämne. Denna uppsats ämnar svara på vilket användarskapat innehåll läsare av webbtidningar föredrar, samt varför de föredrar just detta. Med utgångspunkt i en litteraturstudie identifierades fem aspekter som kan hjälpa till att beskriva UGC.

The communicating home concept has been defined byidentifying the dominating communication technologiesto/from and in the homes, the most important customerbehavior and user needs, the dominating products and thedominating actors of the industry.The evaluation of the communicating home industry has beenperformed with a five forces framework analysis and theoriesregarding value migration and value structures of industries. Ithas been concluded that actors of communication technologies,goods and access services will compete fiercely. The barriersof entry will however be high. When it comes to contentservices the situation is completely different. These actors will,to the largest extent, meet lower competition and low barriersof entry.

The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

Folksonomier, system som låter användare klassificera innehåll, blir allt vanligare på webben. Typiskt sker denna klassificering genom att användare fritt beskriver innehållsobjekt med hjälp av nyckelord. Denna uppsats presenterar en underökning av hur nyckelord förhåller sig till varandra hierarkiskt, inom ett folksonomisystem. Undersökningen är baserad på ett webbgränssnitt, där besökare kunde förfina eller förkasta förslag på hierarkier av nyckelord. Dessa förslag genererades utifrån av ett verkligt folksonomisystem. Efter analys av 400 inkomna svar dras slutsatsen att flera aspekter av metodologin måste förfinas för att tydliga resultat ska kunna uppnås. Förslag på sådana förändringar presenteras slutligen..

This thesis treats the topic of user-generated comments connected with news stories on news sites, meaning electronic word-of-mouth combined with PR. The writers have examined how different types of comments affect consumers' perception of the article and also what communication effects these comments generate in terms of attitudes, purchase intent and word-of-mouth intent. The results interesting to the news site owners, is that lots of comments and negative comments generate a negative effect by making the actual article less credible, attractive and worth reading (relative to the subsequent comments). On the positive side, serious comments imply that the news story is perceived as more interesting, than a news story followed by non-serious comments. From a brand equity perspective, the interesting results show that few comments compared to lots of comments, generate a better attitude to the brand, even though there is no difference in how positive or negative the comments are.

In my study, I have chosen to examine how the user interface and content must conform to design guidelines for responsive design makes it suitable for diverse desktop environment and for varied mobile platforms. The purpose of this study is to examine the extent recommended design guidelines based on scientific research has a positive impact on user performance and perception when using this study delivered hi-fi prototype. The goal of this study is to provide a Hi-Fi prototype with high usability that will introduce and inform the public about BrasilCine according specifications. Study findings from user testing and supplementary questionnaires show that the implemented technologies as design guidelines for responsive design and design features have a positive impact on user performance and perception. The study results are therefore relevant for further prototype development..
