  1. 1. Understanding Multicore Performance : Efficient Memory System Modeling and Simulation

    Författare :Andreas Sandberg; Erik Hagersten; David Black-Schaffer; David A. Wood; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; Simulation; Modeling; Sampling; Caches; Memory Systems; gem5; Parallel Simulation; Virtualization; Sampling; Multicore; Datavetenskap; Computer Science;

    Sammanfattning : To increase performance, modern processors employ complex techniques such as out-of-order pipelines and deep cache hierarchies. While the increasing complexity has paid off in performance, it has become harder to accurately predict the effects of hardware/software optimizations in such systems. LÄS MER

  3. 2. Switched Bond Graphs : Simulation and Analysis

    Författare :Krister Edström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bond graphs; Hybrid systems; Modeling; Simulation; Causality; Discontinuities;

    Sammanfattning : In this thesis an approach to modeling and simulation of mode switching systems is investigated. This approach, switched bond graphs, is an extension of the bond graph language in the sense that it allows modeling of mode switching phenomena.The classical bond graph language as well as the switched bond graph language are presented.

  4. 3. Modeling and Simulation of Physical Systems in a Mechatronic Context

    Författare :Carl-Johan Sjöstedt; Martin Törngren; Hans Vangheluwe; KTH; []
    Nyckelord :mechatronics; MATLAB Simulink; SysML; bond graphs; Modelica; Simscape; simulation; modeling; EAST-ADL2; physical modeling; Mechanical engineering; Maskinteknik;

    Sammanfattning : This thesis gives different views on the modeling and simulation of physical systems, especially together with embedded systems, forming mechatronic systems. The main considered application domain is automotive. LÄS MER

  5. 4. Rigorous Simulation : Its Theory and Applications

    Författare :Adam Duracz; Walid Taha; Veronica Gaspes; Kazunori Ueda; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; simulation; verification; interval analysis; validated numerics; hybrid systems; cyber-physical systems;

    Sammanfattning : Designing Cyber-Physical Systems is hard. Physical testing can be slow, expensive and dangerous. Furthermore computational components make testing all possible behavior unfeasible. Model-based design mitigates these issues by making it possible to iterate over a design much faster. LÄS MER

  7. 5. Track circuits’ robustness : Modeling, measurement and simulation

    Författare :Emilio Rodriguez; Ajit Kumar Verma; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track circuit; Relay; False positive signals; Signalling in railway; Modelling; Simulation; Testing; Robustness; Interoperability; Reliability; Railway Infrastructure; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. LÄS MER
