  1. 21. Theoretical Aspects on Performance Bounds and Fault Tolerance in Parallel Computing

    Författare :Kamilla Klonowska; Blekinge Institute of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of two parts: performance bounds for scheduling algorithms for parallel programs in multiprocessor systems, and recovery schemes for fault tolerant distributed systems when one or more computers go down. In the first part we deliver tight bounds on the ratio for the minimal completion time of a parallel program executed in a parallel system in two scenarios. LÄS MER

  3. 22. High performance fiber-optic interconnection networks for real-time computing systems

    Författare :Magnus Jonsson; Bertil Svensson; Timothy M. Pinkston; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fiber-optic communication; real-time communication; Computer engineering; Datorteknik;

    Sammanfattning : Parallel and distributed computing systems become more and more powerful and hence place increasingly higher demands on the networks that interconnect their processors or processing nodes. Many of the applications running on such systems, especially embedded systems applications, have real-time requirements and, with increasing application demands, high-performance networks are the hearts of these systems.

  4. 23. A Comparative Study of the Performance of Concurrency Control Algorithms in a Centralised Database

    Författare :Donald F Ross; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Sammanfattning : "The performance of Concurrency Control Algorithms (CCAs) in databases has been widely studied over the last ten years, mainly using analytic and simluation techniques. Results have been contradictory. The main CCA categories to emerge are locking, timestamping and serial validation. LÄS MER

  5. 24. Improving Performance of Feedback-Based Real-Time Networks using Model Checking and Reinforcement Learning

    Författare :Gautham Nayak Seetanadi; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model checking; Reinforcement learning; Event-based resource allocation; Camera networks; Real-Time routing; Dual-delay model;

    Sammanfattning : Traditionally, automatic control techniques arose due to need for automation in mechanical systems. These techniques rely on robust mathematical modelling of physical systems with the goal to drive their behaviour to desired set-points. LÄS MER

  7. 25. Control of Constrained Dynamical Systems with Performance Guarantees: With Application to Vehicle motion Control

    Författare :Ankit Gupta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear matrix inequalities; Robust control; Invariant set; Semi-definite program; Linear parameter varying system; Linear fractional transformation;

    Sammanfattning : In control engineering, models of the system are commonly used for controller design. A standard control design problem consists of steering the given system output (or states) towards a predefined reference. Such a problem can be solved by employing feedback control strategies.
