  1. 16. Damage mechanics analysis of inelastic behaviour of fiber composites

    Författare :Peter Lundmark; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Composite laminates under service loading undergo complex combinations of thermal and mechanical loading, leading to microdamage accumulation in the plies. The first mode of damage is usually intralaminar cracking with the crack plane transverse to the laminate middle-plane, spanning the whole width of the specimen. LÄS MER

  3. 17. Image analysis and interactive visualization techniques for electron microscopy tomograms

    Författare :Lennart Svensson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Images are an important data source in modern science and engineering. A continued challenge is to perform measurements on and extract useful information from the image data, i.e., to perform image analysis. LÄS MER

  4. 18. Numerical methods for waveguide modelling

    Författare :Christer Johansson; Björn Engquist; Per Lötstedt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Waveguide; finite element; hp-adaptivity; helmholtz; maxwell; Numerical analysis; Numerisk analys;

    Sammanfattning : Waveguides are used to transmit electromagnetic signals. Their geometry is typically long and slender. This particular shape can be used in the design of efficient computational methods. Only special modes are transmitted and eigenvalue and eigenvector analysis becomes important. LÄS MER

  5. 19. Efficiency and Mixing Analysis of EGR-Systems for Diesel Engines

    Författare :Simon Reifarth; Hans-Erik Ångström; Nils Tillmark; Andreas Cronhjort; José Galindo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EGR; Exergy; mixing; pulsating flow; HP-EGR; LP-EGR; high-pressure EGR; low-pressure EGR;

    Sammanfattning : The reduction of fuel consumption and the reduction of toxic emissions are the main goals of research and development in the area of internal combustion engines. The use of exhaust gas recirculation (EGR) to come further in that direction is today an established method for diesel engines. LÄS MER

  7. 20. Shadows of Cavernous Shades: Charting the Chiaroscuro of Realistic Computing

    Författare :Erik Persson; Data Vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; history of computing; philosophy of technology; philosophy of computing; realistic computing; virtual reality; object-orientation; business objects; software components; client server database access architectures; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

    Sammanfattning : During the early 1990s, a novel style of programming often referred to as component-oriented programming quickly grew popular as the state-of-the-art in graphical user interface and client/server development on Windows-based personal computers, largely in competition with object-oriented programming, a partly similar, partly different programming paradigm, with which component-orientation is often compared, combined, and confused. Also during the 1990s, the world-wide web spread its arachnoid gossamer over the globe with deep-ranging ramifications for software component technology. LÄS MER
