2. 1. Tailoring native compilation of Java for real-time systems

   Author : Anders Nilsson; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; systems; numerical analysis; Java; embedded systems; real-time; aspect-oriented; object-oriented; Computer science; compiler construction; control; Datalogi; numerisk analys; system; kontroll;

   Abstract : Our everyday appliances ranging from toys to vehicles, as well as the equipment used to manufacture them, contain an increasing number of embedded computers. Embedded systems software often implement functionality that is crucial for the operation of the device, resulting in a variety of timing requirements and resource utilization constraints to be fulfilled.

4. 2. Robust Real-Time Estimation of Region Displacements in Video Sequences

   Author : Johan Skoglund; Michael Felsberg; Hanno Scharr; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tracking; subpixel; real time; covariance; pose estimation; Image analysis; Bildanalys;

   Abstract : The possibility to use real-time computer vision in video sequences gives many opportunities for a system to interact with the environment. Possible ways for interaction are e.g. augmented reality like in the MATRIS project where the purpose is to add new objects into the video sequence, or surveillance where the purpose is to find abnormal events.

5. 3. Virtual Full Replication for Scalable Distributed Real-Time Databases

   Author : Gunnar Mathiason; Sten F. Andler; Sang H. Son; Hans Hansson; Alejandro Buchmann; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scalability; Flexibility; Adaptiveness; Database Replication; Resource Management; Distributed Database; Real-time Database; Computer science; Datalogi; Information technology; Informationsteknik; Teknik;

   Abstract : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.

6. 4. Active Distributed Power Systems Functional Structures for Real-Time Operation of Sustainable Energy Systems

   Author : Jörgen Svensson; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Distributed power systems; RES; Power electronics; Energy management system; Real-time operation; Advanced functions; Communication; Elektronik och elektroteknik; Electronics and Electrical technology; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : Present power system will face great challenges in several areas depending on the market economy, extensive global integration and constant need for more electric power, which will force the system to operate much closer to its stability limits. Meeting these challenges may involve improving and complementing or even total restructuring of the power systems. READ MORE

7. 5. QoS Control of Real-Time Data Services under Uncertain Workload

   Author : Mehdi Amirijoo; Jörgen Hansson; Sang Son; Svante Gunnarsson; Joseph Hellerstein; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; real-time system; database; feedback control; Computer science; Datavetenskap;

   Abstract : Real-time systems comprise computers that must generate correct results in a timely manner. This involves a wide spectrum of computing systems found in our everyday life ranging from computers in rockets to our mobile phones. The criticality of producing timely results defines the different types of realtime systems. READ MORE
