  1. 31. On Computational Homogenization of Fluid-filled Porous Materials

    Författare :Carl Sandström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; homogenization; Darcy flow; porous materials; multiscale modeling; Stokes flow;

    Sammanfattning : Porous materials are present in many natural as well as engineered structures. Engineering examples include filters, sanitary products and foams while examples of natural occurrences are oil reservoirs and biological tissue. LÄS MER

  3. 32. Visual Inertial Navigation and Calibration

    Författare :Martin A. Skoglund; Fredrik Gustafsson; Thomas Schön; Henk Luinge; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Processing and interpretation of visual content is essential to many systems and applications. This requires knowledge of how the content is sensed and also what is sensed. Such knowledge is captured in models which, depending on the application, can be very advanced or simple. LÄS MER

  4. 33. Computational Modeling of Liquid-Phase based on Homogenization

    Författare :Mikael Öhman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Homogenization; Liquid Phase Sintering; FE2;

    Sammanfattning : Liquid-phase sintering is the process where a pre-compacted powder, "green body", is heated to the point where(a part of) the solid material melts, and the specimen shrinks while keeping (almost) net shape. In the case of hardmetal, the microstructure is defined by WC-Co-particles with large pores, whereby molten Co represents the liquid phase. LÄS MER

  5. 34. Computational methods for shape verification of free-form surfaces

    Författare :Per Bergström; Mårten Gulliksson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teknisk vetenskapliga beräkningar; formverifiering; online; formmätning; Scientific Computing; Teknisk-vetenskapliga beräkningar;

    Sammanfattning : Beräkningsmetoder för formverifiering av friformsytor utgör huvudinnehållet i denna doktorsavhandling. En gemensam egenskap för dessa metoder är att de möjliggör formverifiering online direkt i produktionslinan. Av den anledningen måste metoderna vara snabba och robusta. LÄS MER

  7. 35. On Robust LPC-spectrum Coding and Vector Quantization

    Författare :Roar Hagen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robustness against channel noise; LPC-spectrum coding; vector quantization; speech coding; linear mapping of a block code;

    Sammanfattning : Digital speech coding is concerned with representing a discrete-time speech signal with as few bits per second as possible without introducing annoying artifacts in the coded speech. Many modern speech coders are based on Linear Predictive Coding (LPC) which employ a source-filter model for speech production. LÄS MER
