Hantering av QoS i Distribuerade MPEG-videosystem
With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.
Distributed Operations : En förmåga eller en metod?
Uppsatsen behandlar det amerikanska konceptet Distributed Operations (DO) kopplat mot den svenska doktrinutvecklingen. Uppsatsen bygger på Mika Ihalainens uppsats om DO som en framtida upprorsbekämpningsmetod. Uppsatsen avser fortsätta på Mika Ihalainens uppsats, och då främst med hans egna förslag på vidare forskning. Syftet med uppsatsen är att besvara frågeställningen ?Är Distributed Operations en förmåga eller en metod utifrån hur konceptet nyttjades under Falklandskriget?? och att ge ett konceptexempel på hur den svenska Försvarsmakten kan hantera en lågtek-nologisk fiende samt bidraga till den svenska doktrinutvecklingen, framförallt genom en definition av begreppen förmåga och metod.
Ledarskap inom ramen för ett systemutvecklingsprojekt - fokus på en arbetsprocess med stöd i Vattenfallsmodellen
Many research reports mention the fact that a huge number of all system
development projects never reach a successful ending; with other words never
fulfil formulated goals. By identifying and forming success factors (and in
some aspect risk factors) that the project manager in practice can use, this
study may be seen as a step in the direction towards minimising the high number
of failed system development projects.
The purpose of this research report is to investigate how a system development
project, where the development process is based on a specific development or
process model (in this case the Waterfall model), can and should be driven. I
aim to clarify what is demanded of a project leader for the specific
development process and give an account for which eventual leadership qualities
that can be well suited for given situation in relation to the need for
technical competence.
Among other things the project manager should inspire confidence, drive, be a
decision maker, engage and own some form of basic knowledge in the field of
system development.
Datorspel - en lek eller sport? : En studie om hur tre svenska dagstidningar framställer e-sport och datorspel 2000-2013
This essay examines how three big Swedish newspapers depicts e-sports and computer gaming and how the depiction change during 2000-2013. The study will also examine whether e-sports is being portrayed as competitive sport. The purpose is to investigate which attitudes that can be identified towards computer gaming and its culture in major newspapers such as Aftonbladet, Dagens Nyheter and Svenska Dagbladet and how these attitudes eventually changed over time. The sources that will be used in both the quantitative and qualitative analysis are based on web articles, mainly because the paper editions does not provide much, if any, information about computer gaming and e-sports and also because of the convenience of being able to quickly find articles to study. Results indicate that computer gaming is being depicted in a clear negative fashion during 2000-2006, and that the depiction of e-sports is somewhat positive but not as glorifying as for the years 2007-2013. During this period, there is a apparent tendency of e-sports being introduced to readers who are unfamiliar with the gaming culture. As for the attitudes towards computer gaming, the depiction is still somewhat negative, mainly because the debate about computer games and violence was revived because of several acts of violence in shape of school massacres and mass murder.
De autistiska barnens dataprogram - hur bör de vara?
This report presents a study of the basic criteria for computer programmes that may be consideredadequate for aiding children with autism in their education and upbringing. I have based thisstudy on descriptions, opinions and proposals from people who deal with treatment and/orother issues concerning children with autism, as well as relevant literature.The study has been carried out in a major Swedish metropolitan municipality. The intervieweeswere civil servants from this municipality and representing different institutional endeavourson the issue of autism.I used a combination of both quantitative and qualitative techniques, as there was need for bothstandardization and qualitative variation. The main aim of the study was to seek suggestionson how computer programmes should be. That is, if they are to be considered appropriate föraiding children with autism develop their personality.The general conclusion of this study is that computer programmes, that may be consideredappropriate for the above mentioned purpose, should have certain characteristics of whichpedagogic usefulness and user suitability are of primary importance..
Autentisering i programvaruapplikationer
Dagens människa är ytterst beroende av webbtjänster och med tiden har det
blivit fler och
viktigare tjänster som startat upp på internet. Viktiga tjänster som
internetbanker. Oftast är
det bara ett användarnamn och ett lösenord som krävs för att bli autentiserad
så man skulle
kunna tro att användarna håller hårt i sina lösenord och att de väljer
starka/unika lösenord.
För många verkar det dock, enligt källor, vara ett besvär. Borde man ha
associeringar för att
lätt komma ihåg sitt lösenord eller är det för riskabelt? Det har visat att
många tycker om att
använda ord som förknippas med webbsidan.
Pensionären och paddan : En studie av pensionärers upplevelser av läsplattor
Portable IT devices such as laptops, smart phones and computer tablets are becoming ever more ubiquitous. At the same time, the population of the Western world is growing older, with aging bringing about changes with regards to individuals' physical and mental capabilities. These facts raises important questions about how well suited these devices are for use by elderly people. This study focuses on the cognitive aspects of the devices' usability, using the concept of mental models to analyze the users' understanding of a computer tablet. It also draws upon theory of graphical user interfaces in its analyses.

Do the both pictures agree?Method/Material: Together with literature studies, a qualitive method has been used.Two interviews with the managers of Science Park, and five focusgroups with students havebeen conducted.Main Results: The main result from the focusgroup interviews shows that the students perceived image of Science Park correlates in many ways with Science Parks profile. But the study also shows that Science Park do not apply many of the relevant theories that would benefit their marketing..
Deadwood in piles or distributed : does it make any difference to saproxylic beetles?
Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofpiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent pile positions (up and low) was studied and compared to distributed deadwood samplesaround each pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, pile volume and decay stage were assessed to define any effect.
Den statsvetenskapliga diskursen : En innehållsanalys av statsvetenskapliga doktorsavhandlingar 2000-2013
A possible "discursive turn" is believed to have been observed within Swedish political science in later years. The purpose of this study is to examine whether or not such a turn has actually taken place, in order to further determine if a resulting theoretical homogeneity poses a risk to the ability of Swedish political science to identify and respond to its full width of possible research problems, and to determine its perspectives on both these problems and the results that are later communicated to the general society. To do so, the study poses the following primary research question:"Has a discursive turn occurred within Swedish political science?"This question is then broken down into two specified research questions."Has discourse analysis become a more common approach for doctoral dissertations in political science during the period of 2000-2013?""Have ideas corresponding with discourse theory become more common within doctoral dissertations in political science that are not pure discourse analyses during the period of 2000-2013?"These questions are then answered by examining all known 406 doctoral dissertations in political science published in Sweden during the 21st century up until (and including) the year of 2013, using two forms of content analysis, one manual and one computer-assisted. The study finds no clear evidence of a discursive turn in Swedish political science since the turn of the century.
Facebook och ansikte mot ansikte-kommunikation : En undersökning bland 100 ungdomar i Karlstads kommun om deras kommunikativa vanor
This essay deals with the subject of communication through Facebook. In this survey we studied 100 youths from Karlstad and their communication habits and behavior patterns on Facebook.

This paper wants to study what happens to other types of communication.
Användare från båda håll ? Utökat informationsstöd inom design av registreringsprocesser
During spring 2001 we have been involved with our bachelor thesis at Doberman
Digital Agency, an Internet related webdesign company. We have focused our work
on the registration process via digital medias such as the Internet. During our
workprocess we have been conducting a number of studies and analyses of
workrelated materials. Ethnographical methods such as structured interviews and
participant observations were primarily used in our work. We also widely used
brainstorming in our designprocess.

A tricycle construction was chosen because it?s the simplest. Communication between the robot and the computer also kept as simple as possible..
Stereotyper i den virtuella världen. Hur visuella intryck påverkar deltagares uppfattningar av virtuella agenter
The purpose of this study is to examine how participants perceive virtual agents shown on a computer display. In particular, it is explored to what extent participants transfer gender and attraction stereotypes that are commonly applied in the physical world to virtual agents. Previous related studies have often explored only text or voice interfaces, without any visually appearing agents, and here indeed found evidence for a transfer of gender stereotypes. Our hypothesis was that the addition of a visual agent interface would reinforce this effect. The results support our hypothesis that participants transfer human gender and attraction stereotypes onto virtual agents, as well as that these processes are affected by the visual representations of the agents..
Agil projektmetodik - En studie av den agila metodiken och Scrums inverkan på IT-projekt
