  1. 6. Stability of Adaptive Distributed Real-TimeSystems with Dynamic Resource Management

    Författare :Sergiu Rafiliu; Petru Eles; Zebo Peng; Luigi Palopoli; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; distributed embedded systems; control systems; scheduling; adaptive system;

    Sammanfattning : Today's embedded distributed real-time systems, are exposed to large variations in resource usage due to complex software applications, sophisticated hardware platforms, and the impact of their run-time environment. As eciency becomes more important, the applications running on these systems are extended with on-line resource managers whose job is to adapt the system in the face of such variations. LÄS MER

  5. 9. On MIMO Systems and Adaptive Arrays for Wireless Communication : Analysis and Practical Aspects

    Författare :Mattias Wennström; Michael A. Jensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; antenna array; calibration; MIMO system; flat fading; non-linear amplifier; switched parasitic antenna; analog beamformer; adaptive antenna testbed; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

    Sammanfattning : This thesis is concerned with the use of multiple antenna elements in wireless communication over frequency non-selective radio channels. Both measurement results and theoretical analysis are presented. New transmit strategies are derived and compared to existing transmit strategies, such as beamforming and space-time block coding (STBC). LÄS MER

  7. 10. Advances on Adaptive Fault-Tolerant System Components: Micro-processors, NoCs, and DRAM

    Författare :Alirad Malek; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network-on-Chip; Quality-of-Service; Main memory; Micro-processors; Error-Correcting Codes; Reliability analysis; Adaptive fault tolerance;

    Sammanfattning : The adverse effects of technology scaling on reliability of digital circuits have made the use of fault tolerance techniques more necessary in modern computing systems. Digital designers continuously search for efficient techniques to improve reliability, while keeping the imposed overheads low. LÄS MER
