  1. 1. Dependable Distributed Control System : Redundancy and Concurrency defects

    Författare :Bjarne Johansson; Thomas Nolte; Alessandro Papadopoulos; Luis Almeida; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Intelligent devices, interconnectivity, and information exchange are characteristics often associated with Industry 4.0. A peer-to-peer-oriented architecture with the network as the system center succeeds the traditional controller-centric topology used in today's distributed control systems, improving information exchange in future designs.

  3. 2. Distributed System Simulation Methods : For Model-Based Product Development

    Författare :Robert Braun; Petter Krus; Nigel Johnston; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Distributed system simulation can increase performance, re-usability and modularity in model-based product development. This thesis investigates four aspects of distributed simulation: multi-threaded simulations, simulation tool coupling, distributed equation solvers and parallel optimization algorithms. LÄS MER

  4. 3. Distributed k-ary System: Algorithms for Distributed Hash Tables

    Författare :Ali Ghodsi; Seif Haridi; Alexander Reinefeld; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; distributed hash tables; structured overlay networks; distributed algorithms; distributed systems; group communication; replication; Computer science; Datavetenskap;

    Sammanfattning : This dissertation presents algorithms for data structures called distributed hash tables (DHT) or structured overlay networks, which are used to build scalable self-managing distributed systems. The provided algorithms guarantee lookup consistency in the presence of dynamism: they guarantee consistent lookup results in the presence of nodes joining and leaving. LÄS MER

  5. 4. !secure(system) <=?=> !safe(system) : On Security and Safety of Industrial Software Systems

    Författare :Marcus Lindner; Per Lindgren; Valeriy Vyatkin; Knut Åkesson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; hard real-time; concurrency; model of computation; safety-critical; safety; security; industrial automation; RTFM; real-time for the masses; Embedded Systems; Inbyggda system;

    Sammanfattning : The focus of our research work is on readily accessible, embedded, real-time development with concurrency support. To this end, we develop the Real-Time For the Masses (RTFM) programming framework with a model of computation based on tasks and resources and that stipulates a timing semantics. LÄS MER

  7. 5. Multi-Threaded Distributed System Simulations : Using Bi-Lateral Delay Lines

    Författare :Robert Braun; Petter Krus; Asko Ellman; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : As the speed increase of single-core processors keeps declining, it is important to adapt simulation software to take advantage of multi-core technology. There is a great need for simulating large-scale systems with good performance. LÄS MER
