  2. 2. Computational methods for shape verification of free-form surfaces

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

    Abstract : 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. READ MORE

  3. 3. Mathematical Modelling of Light Scattering in Paper and Print

    Author : Per Edström; Mårten Gulliksson; Inge Söderkvist; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; radiative transfer; solution method; numerical stability; speed; light scattering; light absorption; Kubelka-Munk; errors; reflectance calculations; MATHEMATICS; MATEMATIK;

    Abstract : A problem formulation and a solution method are outlined for the radiative transfer problem in vertically inhomogeneous scattering and absorbing media, using discrete ordinate model geometry. The treatment spans from the physical problem via a continuous formulation, a discretization and a numerical analysis, to an implementation with performance evaluation and application to real-world problems.

  4. 4. G-Convergence and Homogenization of some Sequences of Monotone Differential Operators

    Author : Liselott Flodén; Anders Holmbom; Nils Svanstedt; Mårten Gulliksson; Björn Birnir; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; G-convergence; Homogenization; Multiscale convergence; Two-scale convergence; Monotone opertors; Functional analysis; Partial differential equations; Mathematical analysis; Analys;

    Abstract : This thesis mainly deals with questions concerning the convergence of some sequences of elliptic and parabolic linear and non-linear operators by means of G-convergence and homogenization. In particular, we study operators with oscillations in several spatial and temporal scales. READ MORE

  5. 5. New methods for movement technique development in cross-country skiing using mathematical models and simulation

    Author : Marie Lund Ohlsson; Mårten Gulliksson; Lars-Erik Persson; Fredrik Ståhl; Peter Carlsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied mathematics; Tillämpad matematik;

    Abstract : This Licentiate Thesis is devoted to the presentation and discussion of some new contributions in applied mathematics directed towards scientific computing in sports engineering. It considers inverse problems of biomechanical simulations with rigid body musculoskeletal systems especially in cross-country skiing. READ MORE
