  1. 21. Contributions to parallel multiparadigm languages : combining object-oriented and rule-based programming

    Författare :Eva Toller; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Today, object-oriented programming is widely used as a practical tool. For some types of complex applications, the object-oriented style needs to be complemented with other types of programming paradigms into a multiparadigm language. One candidate for such a complement is the rule-based programming paradigm. LÄS MER

  3. 22. Advances in Task-Based Parallel Programming for Distributed Memory Architectures

    Författare :Afshin Zafari; Elisabeth Larsson; George Bosilca; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel programming; task-based programming; distributed memory system; scientific computing; hierarchical data; hierarchical tasks;

    Sammanfattning : It has become common knowledge that parallel programming is needed for scientific applications, particularly for running large scale simulations. Different programming models are introduced for simplifying parallel programming, while enabling an application to use the full computational capacity of the hardware. LÄS MER

  4. 23. Numerical Investigations of Turbulent Flow in Water Turbines

    Författare :Håkan Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiblock; Parallel; Visualization; Validation; Verification; Turbine; CFD; Francis; Numerical; Kaplan;

    Sammanfattning : This thesis investigates turbulent flow in water turbines, focusing onthe flow in the vicinity of reaction water turbine runners such as theKaplan runner and the Francis runner. The method of investigationis principally numerical although some experimental observations andmeasurements made in the present work and elsewhere are included. LÄS MER

  5. 24. Krylov Subspace Methods for Linear Systems, Eigenvalues and Model Order Reduction
