  1. 1. 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

  3. 2. Thermally stable electrical contacts to 6H silicon carbide

    Författare :Nils Lundberg; Mikael Östling; Claude Jaussaud; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; I-V current -voltage ; C-V capacitance-voltage ; rectifying; ohmic; interface; silicide; carbide; epilayer; Schottky barrier height; current rectification ratio CRR ; specific contact resistivity; transmission line model TLM ; contact resistance; transfer length; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Silicon Carbide (SiC) are at present being developed for use in high temperature (≥ 500◦C) and high-power environments under which conventional semiconductors can hardly perform.  Thermally stable electrical contacts are essential to the ability of SiC to function under such extreme conditions.

  4. 3. Model‐Based Tool Integration and Ontology‐Driven Traceability in Model‐Based Development Environments

    Författare :Alachew Mengist; Adrian Pop; Peter Fritzson; Juan Llorens; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The landscape of tools available for model-based development of Cyber-Physical Systems (CPSs) is vast, encompassing numerous specialized tools designed to support models at the component-level. In reality, the different parts of the system represented by these component-level models are often physically tightly coupled and interdependent, and the models themselves are subject to change and evolve over time.

  5. 4. 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
