  1. 1. Homogenization of some linear and nonlinear partial differential equations

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Niklas Wellander; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : In this thesis is studied two-scale convergence for sequences of linear and nonlinear evolution problems. In particular homogenization procedures, correctors and a numerical algorithm for such problems are studied. The main results are the following: We prove a crucial compactness results of two-scale convergence type. LÄS MER

  3. 3. Absorbing Layers and Non-Reflecting Boundary Conditions for Wave Propagation Problems

    Detta är en avhandling från Stockholm : KTH

    Författare :Daniel Appelö; Prof. Gunilla Kreiss; Eliane Becache; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PML; perfectly matched layer; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Sammanfattning : The presence of wave motion is the defining feature in many fields of application,such as electro-magnetics, seismics, acoustics, aerodynamics,oceanography and optics. In these fields, accurate numerical simulation of wave phenomena is important for the enhanced understanding of basic phenomenon, but also in design and development of various engineering applications.
