  2. 21. Simulation and Electrical Evaluation of 4H-SiC Junction Field Effect Transistors and Junction Barrier Schottky Diodes with Buried Grids

    Author : Jang-Kwon Lim; Hans-Peter Nee; Mietek Bakowski; Ichiro Omura; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide SiC ; junction field-effect transistors JFETs ; junction barrier schottky diode JBS ; schottky barrier diode SBD ; buried-grid BG technology; simulation; implantation; epitaxial growth; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Silicon carbide (SiC) has higher breakdown field strength than silicon (Si), which enables thinner and more highly doped drift layers compared to Si. Consequently, the power losses can be reduced compared to Si-based power conversion systems. Moreover, SiC allows the power conversion systems to operate at high temperatures up to 250 oC. READ MORE

  4. 22. Towards a Power and Performance Simulation Framework for Parallel DSP Architecture

    Author : Minh Quang Do; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DSP architecture; Power estimation models; Power estimation simulation;

    Abstract : High performance, low power and low cost will continue to be driving factors for digital signal processor (DSP) and embedded computer systems of the future. Recent improvements of semiconductor technology have led to faster circuits, higher density, and smaller dimensions. READ MORE

  5. 23. CMOS Parallel-Sampling Receivers

    Author : Henrik Johansson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  6. 24. Parallel computing in model-based process engineering

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

    Abstract : 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. READ MORE

  7. 25. A Large Eddy Simulation Based Fluid-Structure Interaction Methodology with Application in Hydroelasticity

    Author : Andreas Feymark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydroelasticity; subgrid modeling; large eddy simulation; trip model; fluid- structure interaction; numerical simulation; forced oscillation; naval architecture; hydrodynamics;

    Abstract : The phenomenon of hydroelasticity is a subarea of Fluid-Structure Interaction (FSI) and of major importance in many engineering applications related to hydrodynamics and naval architecture e.g. READ MORE
