1. 11. CPU Resource Management and Noise Filtering for PID Control

   Författare :Vanessa Romero Segovia; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource management; embedded systems; real-time systems; multimedia; multicore; measurement noise; filtering; trade-offs; robustness; performance; SDU; noise gain; PID control;

   Sammanfattning : The first part of the thesis deals with adaptive CPU resource management for multicore platforms. The work was done as a part of the resource manager component of the adaptive resource management framework implemented in the European ACTORS project. The framework dynamically allocates CPU resources for the applications. LÄS MER

3. 12. Multimedia representations of distributed tactical operations

   Författare :Magnus Morin; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : Our society frequently faces minor and major crises that require rapid intervention by well-prepared forces from military organizations and public-safety agencies. Feedback on the performance in operations is crucial to maintain and improve the quality of these forces. LÄS MER

4. 13. On technologies for ubiquitous multimedia communication

   Författare :Johan Kristiansson; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

   Sammanfattning : The proliferation of multimedia and deployment of wireless networks over the last decade have made it possible for users to communicate and share information using e-meeting services from almost any location at anytime. While these new services offer new ways to communicate, they are not always easy to use because of the heterogeneity of networks and devices, which must be managed by the users to take full advantage of the possible benefits.

5. 14. Preferential Coding for Mobile Multimedia Services

   Författare :Muhammad Imran Iqbal; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Different parts of source encoded multimedia streams such as those associated with standard image or video formats possess different levels of importance with respect to their contribution to the quality of the reconstructed image or video. This unequal importance among data within a codestream gives rise to preferential treatment of the more significant parts of the codestream compared to the less important parts. LÄS MER

7. 15. Robust Multimedia Communications over Packet Networks

   Författare :Guoqiang Zhang; W. Bastiaan Kleijn; Vinay Vaishampayan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Sammanfattning : Multimedia communications over packet networks, and in particular the voice over IP (VoIP) application, have become an integral part of society. However, the unreliable and heterogeneous nature of packet networks has led to a best-effort delivery of services. LÄS MER
