  1. 6. Application of Parallel Computers to Enhance the Flow Modelling Capability in Aircraft Design

    Författare :Mattias Sillén; Dan Loyd; Peter Eliasson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow modelling; parallel computer; parallel efficiency; turbulence modelling; aircraft design; CFD; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The development process for new aircraft configurations needs to be more efficient in terms of performance, cost and time to market. The potential to influence these factors is highest in early design phases. Thus, high confidence must be established in the product earlier than today. LÄS MER

  3. 7. Techniques to Tighten the Upper Bound on the ExecutionTime of Task-based Parallel Applications

    Författare :Petros Voudouris; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheduling; Multiprocessor; WCET; Uniform; Hard; multicore; Related; DAG; Real-Time; Dynamic; Unrelated; Makespan; Homogeneous; Parallel; Identical;

    Sammanfattning : To use multiprocessors in hard real-time systems, schedulability analysis is needed to provide formally proven guarantees for the timing behavior of the system. Programming models for parallel applications, such as OpenMP, use pragmas to specify parts of the application as parallel tasks, for example, a function or a body of a loop. LÄS MER

  4. 8. Parallel algorithms for solving the train timetable rescheduling problem

    Författare :Sai Prashanth Josyula; Johanna Törnquist Krasemann; Lars Lundberg; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parallel computing; Parallel heuristic search algorithms; Computer Science; Datavetenskap;

    Sammanfattning : In railways, it is essential to achieve high train punctuality. Thus, whenever disturbances occur, it is important to reschedule the trains effectively. This task is typically handled manually by traffic controllers in real-time. LÄS MER

  5. 9. CMOS Parallel-Sampling Receivers

    Författare :Henrik Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As the processing capacity of the microelectronic circuits increases, the demands on the interconnects will also increase. Hence, there is a need for higher bandwidth to the chips. This dissertation discusses the possibilities to improve the input data rate to CMOS integrated circuits, which is the most common integrated circuit technology today. LÄS MER

  7. 10. Parallel computing in model-based process engineering

    Författare :Niklas Andersson; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parallel computing; Parameter estimation; Optimisation; Parameter selection; Model-based engineering;

    Sammanfattning : Chemical processes are usually expensive to run. To optimise a process, we need to know how the process behaves, and this is usually accomplished by studying the process experimentally. However, experiments are very expensive, particularly if an existing plant has to shut down normal operation to conduct an experiment. LÄS MER
