  1. 1. Reiterated homogenization and G-convergence for some sequences of monotone operators

    Author : Marianne Olsson; Mårten Gulliksson; Anders Holmbom; Nils Svanstedt; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Homogenization; G-convergence; Multiple scales; Monotone operators; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis, the main focus is on G-convergence and homogenization of monotone parabolic equations with multiple scales. This kind of equation is examined with respect to existence and uniqueness of the solution, in view of the properties of some monotone operators. READ MORE

  2. 2. G-Convergence and Homogenization of some Monotone Operators

    Author : Marianne Olsson; Anders Holmbom; Nils Svanstedt; Mårten Gulliksson; Jan Françu; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; G-convergence; homogenization; two-scale convergence; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis we investigate some partial differential equations with respect to G-convergence and homogenization. We study a few monotone parabolic equations that contain periodic oscillations on several scales, and also some linear elliptic and parabolic problems where there are no periodicity assumptions.

  3. 3. Synthesis, Coding, and Evaluation of 3D Images Based on Integral Imaging

    Author : Roger Olsson; Youzhi Xu; Mårten Sjöström; Tingting Zhang; Aljoscha Smolic; Mittuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integral Imaging; 3D images; coding; quality evaluation; H.264 AVC; JP3D; Telecommunication; Telekommunikation;

    Abstract : In recent years camera prototypes based on Integral Imaging (II) have emerged that are capable of capturing three-dimensional (3D) images. When being viewed on a 3D display, these II-pictures convey depth and content that realistically change perspective as the viewer changes the viewing position. READ MORE

  4. 4. High Efficiency Light Field Image Compression : Hierarchical Bit Allocation and Shearlet-based View Interpolation

    Author : Waqas Ahmad; Mårten Sjöström; Roger Olsson; Peter Schelkens; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Over the years, the pursuit of capturing the precise visual information of a scenehas resulted in various enhancements in digital camera technology, such as highdynamic range, extended depth of field, and high resolution. However, traditionaldigital cameras only capture the spatial information of the scene and cannot pro-vide an immersive presentation of it. READ MORE

  5. 5. Growth of fatigue cracks subjected to non-proportional Mode I and II

    Author : Peter Dahlin; Mårten Olsson; Veronique École; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue crack growth; Mode II overloading; Crack closure; Sequential mixed mode loading; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : This thesis deals with some aspects of crack growth in the presence of cyclic loading, i.e. fatigue. The cyclic load cases studied here are primary of non-proportional mixed mode type. READ MORE
