This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

In this study I compare the use of reporting verbs in direct speech in Swedish and Polish literary prose. The aim is to examine how differences in usage are reflected in translations to and from Swedish and to what extent the translator adapts the text to the target language and its literary conventions.I have compared the material on two levels: source text versus source text in Polish and Swedish respectively, to see what kind of speech verbs are most commonly used, and source text versus target text, to study the strategies the translators have used and to what extent reporting verbs are altered or not.I have also studied quotation verb + adverbial phrase or prepositional phrase, to investigate if they are more frequent in the two target texts or adapted to the literary concentions of the target language. .

The concept of IT has developed into ICT (Information- and Communication Technology) over the years. ICT has an increasing impact in society and the Swedish curriculum (Lpo 94) highlights the importance of school to convey lasting knowledge that constitutes the general frame of reference that everyone in society is in need of. The purpose of this study was to find out how teachers perceive and use ICT in secondary school and discover the teachers? vision concerning ICT.The used approach for the study is a qualitative research with a basis of interviews. Four interviews are made with teachers from the early years of secondary school, at two different schools.

AbstractIn this text the attitudes towards and using of blogs in teaching Swedish toteenagers will be explored. The results are based on a survey made amongst 17teachers and 58 students from all over Sweden. The end results show that theusage of blog still hasn?t found a permanent way into the classrooms, but has anappeal to and is being used by predominantly younger teachers both, male andfemale, with a positive response from students regardless of gender. Theconclusion is that using web tools like the blog is an easy first step for schools toconnect to the digital society of the 21stcentury and take advantage of the perksavailable in the digital classroom.Svensk titel:Blogg + Svenska =Sant? ?

An increasing number of applications are becoming more or less network based today.The traditional architecture for network based applications is client-server, but as usageof download services are going up, so is the Peer-to-Peer architecture. This report is acomparison between the Peer-to-Peer and client-server model, and can serve as a basiswhen a decision between them needs to be taken. In the report, the performancebetween the different architectures is compared in different contexts. Our basis is ageneral implementation of both architectures in a test that is derived from a previousreport. On top of this, the performance of the different architectures are measured,implemented in a gaming-context.

Our time is characterized by the development of new technologies that facilitate communication between people. The need for Video Mediated Communication (VMC) is increasing because people move to other locations due to migration and global mobility. VMC provides the opportunity for millions of people around the world to ?hang out? and see each other despite the distance in between. The world is "shrinking" because of the Internet and our perception of distance is changing.VMC is becoming increasingly available, in the form of applications like Skype and MSN for mobile phones and computers, and in addition, it?s practically free.The purpose of this thesis is to render a picture of the way in which people use Skype in the private sphere.

Facebook is the most widely used social media in Sweden. It allows the user to easily share the latest from their everyday life, their opinions, as well as communicate with their acquaintances. According to the latest poll from the Foundation for Internet Infrastructure, 33% of teenagers in the ages 12-15 spend their Internet time being active on social media. 63% of these teenagers visit Facebook on daily basis.Herein, we examined how Facebook can be exploited as a complement to the education of the mother tongue. The investigation was performed with a questionnaire as well as a test group that has been supplemented with semi-structured interviews. In conclusion, the study showed promising results in the usage of Facebook with the education.

The purpose of this paper has been to identify which modern search functions user of Smartphones are using, why just these functions are being used, and how they have affected the way users acquire information. Modern search functions in this paper means searches that are not based on text, i.e. ways to search for information by other means than writing something into a search field. To identify this, two studies were conducted, one with a questionnaire being distributed with the help of Google Docs through social networks, and one with four interviews with users of modern search functions for Smartphones. The study showed that even though 76 % of Smartphone users are aware of at least one modern search function, only 29% uses one on a regular basis.

As the 2010 Swedish election was closing in, there was a discussion about how the media represented the different party leaders in a differential and unfair manner. This study aims to identify if there were any differences in how four of these party leaders, Lars Ohly, Maud Olofsson, Fredrik Reinfeldt and Mona Sahlin were treated in four individual questioning sessions on Swedish television. Utilizing conversation analysis the study focuses on identifying differences in the usage of interruptions between the four different sessions. The study also analyzes the aggressiveness of the journalists? questioning and how they designed their questions in the four different sessions.

This paper constitiutes graduate work at the Swedish University of Agriculture Science, the Department of Urban and Rural Development, Ultuna. The main objective of this work has been, in part, using the municipality of Runby as an example, to test different inventory and analysis methods directed towards a sociotopic usage perspective. A secondary objective has been, based on knowledge obtained from current research results concerning the usage of green areas, to transfer the analysis results to a proposal for a free space planning over Runby. People living in the countryside often have good access to nature as well as access to a garden of their own. In the city, however, there are considerably less people that have access to a private outdoor spaces so the parks become a type of public living room for all the inhabitants. Through the lack of private green spaces and through the anonymity of the city, an inviting atmosphere is created towards spending time in the park.

With this study we aim to learn more about the relationship between digitalization and the swedish church. We have interviewed two priests and two other persons ? one who got married about five years ago, and one who, at the time of writing, is getting married in a few weeks. In addition to the interviews we found some earlier research that were relevant to us, which we read and compared to the empirics we got from the interviews. In our study we have taken qualitative research into practice since we want our interviewees to really share their points of view on the organisation?s usage of digital media.

In this Bachelor thesis I explore sound and room as elements in design of user interfaces, both theoretical and practical in a specific application domain, to identify some of the advantages and disadvantage associated with these elements. As application domain I studied email clients and their usage at home amongst students at Blekinge Institute of Technology. In the study I found an activity, which seems to be highly distributed in the physical room where the user is located. The activity was notification of email and could take place in an arbitrary location of the home. I then augmented this activity with ideas from my theoretical assumption about room and sound. The result was a rule-based agent for notification of email, which primarily uses sound as interaction style..
