  1. 1. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

    Författare :Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Datavetenskap med inriktning mot realtidssystem; Computer Science with specialization in Real Time Systems;

    Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER

  2. 2. Configurable Hardware Support for Single Processor Real-Time Systems

    Författare :Susanna Nordström; Lars Asplund; Kristina Lundqvist; Krzysztof Kuchcinski; Mälardalens högskola; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; FPGA; real-time system; real-time kernel; RTOS; real-time operating system; vhdl; embedded system; Computer engineering; Datorteknik; Datavetenskap;

    Sammanfattning : This thesis describes a further development of a building block for programmable devices in embedded systems handling real-time functionality.Embedded systems are included in a variety of products within different technical areas such as industrial automation, consumer electronics, automotive industry, and communication-, and multimedia systems.

  3. 3. Enhancing the Performance of Distributed Real-time Systems

    Författare :Hoai Hoang; Magnus Jonsson; Bertil Svensson; Luís Almeida; Högskolan i Halmstad; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Switched Ethernet; Real-Time Communication; EDF scheduling; Reducation of delay and jitter; Computer science; Datalogi; reduction of delay; real-time communication;

    Sammanfattning : Advanced embedded systems can consist of many sensors, actuators and processors that are deployed on one or several boards, while having a demand of interacting with each other and sharing resources. Communication between different components usually has strict timing constraints. LÄS MER

  4. 4. Real Time Drag Minimization

    Författare :Marianne Jacobsen; Ulf Ringertz; Anders Forsgren; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeronautics; optimization; experimental verification; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis focuses on the use of multiple redundant control surfaces to increase performance during flight. There is no clear-cut definition of performance. It may differ between applications, but here, the amount of drag for a given flight condition is used. LÄS MER

  5. 5. On robust and optimal control : with real time aspects

    Författare :Torbjörn Norlander; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : This thesis deals with several issues in realistic design of control systems, both from a practical and a theoretical point of view. This is done in three papers which are preceded by an introduction and a short discussion on future research on time-varying delays. The first paper discusses the importance of reliable sensors in control systems. LÄS MER
