  1. 1. New Techniques for Building Timing-Predictable Embedded Systems

    Författare :Nan Guan; Wang Yi; Lothar Thiele; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; WCET analysis; cache analysis; abstract interpretation; multiprocessor scheduling; fixed-priority scheduling; EDF; multi-core processors; response time analysis; utilization bound; real-time calculus; scalability; Datavetenskap med inriktning mot realtidssystem; Computer Science with specialization in Real Time Systems;

    Sammanfattning : Embedded systems are becoming ubiquitous in our daily life. Due to close interaction with physical world, embedded systems are typically subject to timing constraints. At design time, it must be ensured that the run-time behaviors of such systems satisfy the pre-specified timing constraints under any circumstance. LÄS MER

  3. 2. Ancillary actor relations : The case of EU’s leading defence primes

    Författare :Pierre Erik Gunnarsson; Peter Thilenius; Hadjikhani Amjad; Martin Lundmark; Fredrik Tell; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ancillary; actor relation; aerospace industry; Aérospatiale; Airbus; BAE; business relations; Dassault; defence acquisition; defence company; defence industry; defence procurement; EADC; EADS; EDA; EDF; EU defence; EU institutions; EU integration; Europeanization; Finmeccanica; IEPG; industrial marketing; Leonardo; SAAB; solutions marketing; strategic industries; project marketing; Thales; Thomson-CSF; OCCAR; Industriell Marknadsföring; försvarsindustri; Försvar; Försvarsindustri;

    Sammanfattning : This longitudinal research project in industrial marketing seeks to understand ancillary actors, specifically what they are, their characteristics, relations and impact on focal relations based on the empirical case of the cross-border relations of EU’s largest defence equipment producing firms (called “primes”). Ancillary actors are approached on four arenas: i) the political setting for EU defence equipment production, ii) the “primes” business relations, e. LÄS MER

  4. 3. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

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

    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

  5. 4. Enhancing the Performance of Distributed Real-time Systems

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

    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

  7. 5. Switched Real-Time Ethernet for Industrial Applications

    Författare :Hoai Hoang; Magnus Jonsson; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Switched Ethernet; Real-time communication; EDF scheduling; Industrial networks;

    Sammanfattning : The research reported in this thesis has been focused on developing and analyzing how to support real-time traffic over a switched Ethernet network without any hardware or protocol modifications. The work has resulted in a proposed systems model, supporting both real-time and non real-time traffic. LÄS MER
