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.

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.

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 authors of this paper intended to study and compare local secondary schools(municipally owned schools) and independent secondary schools(privately owned schools) in Stockholm County. The purpose oft his paper is to explore how secondary schools market themselves and whether the view and use of marketing is different between municipal and independent secondary schools. The essay is by nature multi-case study and interviews were conducted with representatives from four high schools, two municipal and two independent, one representative from Education Committee and one from Privet Schools? Association.The introduction of School reform in 1992 enabled opening of privately owned schools and empirical datas hows that before 1992 secondary schools did not have the same extent of competition and the need of marketing was not widespread, but today there is fierce competition among secondary schools. The introduction of School reform changed the conditions for the Swedish school market, greater freedom of choice led to atougherfight for the students, which in turn increases the competition between secondary schools.

Examensarbetet som beskrivs i denna rapport handlar om en ny teknik för att förbättra säkerheten för flygplan i luften och i närheten av flygplatser. Denna teknik benämns ADS-B (Automatic Dependent Surveillance Broadcast), och är tänkt att göra det möjligt för piloter att själva få information om trafik i närområdet. Nuvarande system baserar sig i huvudsak på visuella observationer från flygledare i kontrolltorn samt radarspaning omkring flygplatserna. Med det nuvarande systemet kommer det att bli både dyrt och svårt att upprätthålla en acceptabel nivå på flygsäkerheten när trafiken ökar. Arbetet har bedrivits i AerotechTelubs regi i Linköping samt med hjälp ifrån företaget Sectra Wireless Technologies AB.

This thesis is made by Carl Persson and Alejandro Saavedra for Gryaab. Gryaab is Gothenburg?s water processing plant and produces about 60 GWh biogas annually with a flow around 1150 Nm3/h. Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.

Examensarbetet är genomfört vid Robotics i Västerås, en enhet inom ABB Automation Technologies AB. Bakgrunden till examensarbetet är en tidigare genomförd kartläggning av företagets kvalitetsbristkostnader som belyst ett flertal problemområden och skapat ett behov av att stärka och effektivisera kvalitetsutvecklingsarbetet. Syftet med examensarbetet är att utvärdera praktisk användning av kvalitetsutvecklingsmetoden Sex Sigma och undersöka behovet av en förbättrad metod för kvalitetsutveckling vid företaget. Författarna avser att presentera en rekommendation för om och hur metoden kan införas och användas. Resultatet av det genomförda arbetet visar på tydliga brister i det utvecklande kvalitetsarbetet vid ABB Robotics inom områden rörande resurser, kompetens och kvalitetsstrategi.

Denna studie ingår i ett forskningsprogram under ledning av professor Caroline Liberg vid Uppsala universitet. Programmet syftar till att utforska nya sätt att se på elevers tidigatextskapande, bland annat genom att fokusera samspelet mellan texters funktion, innehåll och form. Studien utgår från ett vidgat textbegrepp och en dialogisk syn på språkande, där även barn aktivt intar olika sociala positioner gentemot sina medspråkare. Syftet med studien är att studera elevers (årskurs ett) tecknarpositioner i multimodala elevtexter, i termer av dels hur eleverna skapar mening i sina teckningar, dels hur teckningar och det skrivna är relaterade. Sammanlagt har 57 multimodala elevtexter från två olika skrivsituationer i årskurs ett bearbetats i en kvalitativ semiotisk textanalys med en hermeneutisk metodologisk ansats.

This master?s thesis analyzes how cultural policy was problematized in three governmental policy areas; culturalpolicy for the free sector, education policy and popular education policy, during the social democrat Ragnar Edenman?s time (1957-67) as minister of ecclesiasticalaffairs. Earlier research has examined the policy for the free sector, concerning artist?s economic problems. This thesisadds an analysis of the other fields of policy, which were reformed in the 1960?s by the same ministry.

The purpose of the present qualitative study is to create knowledge about librarydigital services and their marketing to patrons with disabilities in Armenia, on theexample of the National Library of Armenia, as well as, to discover opinions of theNLA librarians and patrons with disabilities about the importance of library digitalservices to people with disabilities. Literature review and qualitative interviewing has been employed as methods to collect the empirical data. The results have been analyzed and discussed based on the library-marketing model of marketing research, marketing segmentation, marketing mix strategy and marketing evaluation suggested by Koontz & Gubbin (2010). It has been concluded, that 1) e-accessibility issomething new at the NLA and the NLA does not provide equally available knowledge, resources, services, facilities to patrons with disabilities, because of the following main challenges: lack of continuous funding and support from the state, lack of appropriate facilities and technologies, lack of qualified staff, and historicallyinherited library infrastructure impediments; 2) no library service marketing is conducted to patrons with disabilities at the NLA; 3) the opinions are that provisionwith such services is very important to people with disabilities, since they allow those people to gain access and use information in formats adopted to their various needs, and, of course, they become integrated into the modern society. The important role of a library as a non-discriminator and copyright protector in a developing country when delivering digital library services to patrons with disabilities has also been discovered..

Information Technology (IT) makes it possible to electronically distribute data between actorswho are in geographically diverse areas. Nowadays, information is sent less frequently throughtraditional correspondence in favor of faster electronic equivalents via the internet.Despite effective IT environmentand secure encryption techniques choose some actors to sendinformation through physical delivery. This phenomenon occurs in those working withconfidential information as it is handled by a number of rules and safety regulations.Based on a set of rules and requirements, we have looked over the possibility of sending sensitiveinformation electronically over the internet. The aim was to find general guidelines for howcompanies and organizations should manage and send sensitive information over insecurenetworks. This led us to our research question: How can information be exchanged betweenactors in geographically diverse areas be categorized and encrypted so that it can be transportedover the internet without security or integrity deficiencies?To answer the question, there was a case study at a defense company.

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

The aim of this thesis is to contribute to the field ofinformation politics, in the areas of the future regulationof The Fundamental Law on Freedom of Expression andThe Freedom of the Press Act. The focus of the study is todiscursively examine how ideas and perspectives ontechnological developments are expressed in a pendingSwedish legislative proposal. The empirical data consistsof an interim government report, SOU 2010:68, writtenby Yttrandefrihetskommittén (Committee on Freedom ofExpression) and analysed using Norman Fairclough'sCritical Discourse Analysis. The analysis is conducted onthree levels: a textual level, a discursive practice level anda social practice level.On the textual level we found that the committeecontinously uses significantly charged expressions todescribe technological development. On the discursivepractice level two discourses were identified.

Children and youth inactivity and sedentary at school is increasing. This means that some of the students have a significant unhealthy lifestyle with physical inactivity, which in turn implies risks of suffering from various diseases, including obesity, type 2 diabetes and cardiovascular disease, all related to a sedentary lifestyle. To prevent illness, it is important that children and young people early get a positive attitude towards physical activity.The purpose of this study was to study the causes of child and adolescent physical inactivity in school, based on teachers 'and parents' perspectives.A qualitative research has been selected. To achieve the study objectives, the author has conducted seven semi-structured interviews, with an appropriate choice of five teachers and two parents with children in school. Data was analyzed with a manifest content analysis.The results show that teachers and parents felt that physical activity is a protective factor for children's health.
