  1. 1. Dynamics of Discrete Curves with Applications to Protein Structure

    Author : Shuangwei Hu; Antti J. Niemi; Maxim Zabzine; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Frenet equations; integrable model; folded proteins; discrete curves; Fysik; Physics; Physical Biology; Fysikalisk biologi;

    Abstract : In order to perform a specific function, a protein needs to fold into the proper structure. Prediction the protein structure from its amino acid sequence has still been unsolved problem. The main focus of this thesis is to develop new approach on the protein structure modeling by means of differential geometry and integrable theory. READ MORE

  2. 2. Digital Geometry, Combinatorics, and Discrete Optimization

    Author : Shiva Samieinia; Christer Kiselman; Rikard Bøgvad; Rémy Malgouyres; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Digital geometry; Khalimsky topology; Khalimsky plane; Khalimsky-continuous function; digital straight line segments; discrete optimization; discrete convexity; integral convexity; lateral convexity; marginal function; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : This thesis consists of two parts: digital geometry and discrete optimization. In the first part we study the structure of digital straight line segments. We also study digital curves from a combinatorial point of view. READ MORE

  3. 3. Effects of aperiodic order for Josephson junction arrays and discrete breathers

    Author : Erik Lennholm; Linköpings universitet; []
    Keywords : Aperiodic order; Josephson junction array; Discrete breather;

    Abstract : Effects of the combination of nonlinearities and aperiodic order is studied in this thesis. The nonlinear systems considered are Josephson junction arrays (JJA) and Fermi-Pasta-Ulam (FPU) lattices. Both systems are discrete and one-dimensional. The traveling waves in a JJA are solitons, i.

  4. 4. Stable reduction of curves and tame ramification

    Author : Lars Halvard Halle; Carel Faber; Bas Edixhoven; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; MATHEMATICS; MATEMATIK;

    Abstract : This thesis treats various aspects of stable reduction of curves, and consists of two separate papers. In Paper I of this thesis, we study stable reduction of curves in the case where a tamely ramified base extension is sufficient. READ MORE

  5. 5. Invariancy Methods for Points, Curves and Surfaces in Computational Vision

    Author : Karl Åström; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; curved surface; space curve; planar curve; laser guided vehicles; AGV; autonomous guided vehicles; recognition; reconstruction; image sequence; multiple view geometry; affine; invariant; projective; Mathematics; Matematik;

    Abstract : Many issues in computational vision can be understood from the interplay between camera geometry and the structure of images and objects. Typically, the image structure is available and the goal is to reconstruct object structure and camera geometry. This is often difficult due to the complex interdependence between these three entities. READ MORE
