  2. 16. Simulation of Phosphorus, Zinc and Cadmium Mass Flow in Dairy Farming Systems

    Author : Anna-Karin Modin Edman; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Miljöstudier; Environmental studies; management; Cd; Zn; P; mass balance; system analysis; simulation;

    Abstract : A simulation model, FARMFLOW, was developed for the calculation of phosphorus (P), zinc (Zn) and cadmium (Cd) stocks, flows and balances in different parts of a dairy farming system. The simulated continuous change in element stocks within the farming system enables evaluation of the long-term effects of management practices. READ MORE

  5. 18. Techniques to Tighten the Upper Bound on the ExecutionTime of Task-based Parallel Applications

    Author : Petros Voudouris; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 19. Numerical modeling of auroral processes

    Author : Jörgen Vedin; Kjell Rönnmark; Robert Lysak; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; space plasma physics; auroral acceleration region; auroral current circuit; Alfvén waves; parallel electric fields; equation of state; fluid simulation; PIC simulation; Space physics; Rymdfysik;

    Abstract : One of the most conspicuous problems in space physics for the last decades has been to theoretically describe how the large parallel electric fields on auroral field lines can be generated. There is strong observational evidence of such electric fields, and stationary theory supports the need for electric fields accelerating electrons to the ionosphere where they generate auroras.

  7. 20. Distributed System Simulation Methods : For Model-Based Product Development

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

    Abstract : 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. READ MORE
