  1. 6. High-Efficiency SiC Power Conversion : Base Drivers for Bipolar Junction Transistors and Performance Impacts on Series-Resonant Converters

    Författare :Georg Tolstoy; Hans-Peter Nee; Stig Munk-Nielsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide; Bipolar Junction Transistor BJT ; Resonant converter; Series-resonant converter SLR ; Base drive circuits; High- Efficiency Converters; High-Frequency Converters; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis aims to bring an understanding to the silicon carbide (SiC) bipolar junction transistor (BJT). SiC power devices are superior to the silicon IGBT in several ways. They are for instance, able to operate with higher efficiency, at higher frequencies, and at higher junction temperatures. LÄS MER

  2. 7. Industrialised housing design efficiency

    Författare :Gustav Jansson; Jerker Lessing; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : Industrialised housing has increased its Swedish market share the latest ten years from 2% to 15%. Prefabrication has developed into actual industrialisation, where factories produce not only elements for site assembly, but takes wholesale responsibility for the sales, design, factory production, and assembly of houses.

  3. 8. Models and Methods for Development of DSP Applications on Manycore Processors

    Författare :Jerker Bengtsson; Bertil Svensson; Shuvra S. Bhattacharyya; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parallel processing; manycore processors; high-performance digital signal processing; dataflow; concurrent models of computation; parallel code mapping; parallel machine model; dynamic performance analysis; Computer engineering; Datorteknik;

    Sammanfattning : Advanced digital signal processing systems require specialized high-performance embedded computer architectures. The term high-performance translates to large amounts of data and computations per time unit. The term embedded further implies requirements on physical size and power efficiency. LÄS MER

  4. 9. Data Partitioning Methods and Parallel Block-Oriented PDE Solvers

    Författare :Jarmo Rantakokko; Michael Thuné; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data assimilation; data partitioning; meteorology; multiblock; Navier-Stokes; object-oriented; oceanography; parallel computing; Numerical Analysis; Numerisk analys;

    Sammanfattning : Data partitioning methods for block-structured problems within scientific computing have been studied. The applications are variational data assimilation in meteorology, ocean modeling, and airflow simulation with multiblock grids. LÄS MER

  5. 10. Parallelism in Constraint Programming

    Författare :Carl Christian Rolf; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Parallelism; Constraint Programming; Parallel Consistency; Parallel Search; Distributed Constraint Programming;

    Sammanfattning : Writing efficient parallel programs is the biggest challenge of the software industry for the foreseeable future. We are currently in a time when parallel computers are the norm, not the exception. Soon, parallel processors will be standard even in cell phones. LÄS MER
