  1. 16. On random satisfiability and optimization problems

    Författare :Joel Larsson; Klas Markström; Roland Häggkvist; Victor Falgas Ravry; Stefanie Gerke; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Random graphs; k-SAT; satisfiability; coupon collector; random cover time; threshold phenomenon; concentration of measure; combinatorial probability; perfect matching; assignment problem; local graph limit; mean-field; Mathematics; matematik;

    Sammanfattning : In Paper I, we study the following optimization problem: in the complete bipartite graph where edges are given i.i.d. weights of pseudo-dimension q>0, find a perfect matching with minimal total weight. LÄS MER

  3. 17. Surface Modified Capillaries in Capillary Electrophoresis Coupled to Mass Spectrometry : Method Development and Exploration of the Potential of Capillary Electrophoresis as a Proteomic Tool

    Författare :Aida Zuberovic; Jonas Bergquist; Ziad El Rassi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Topology optimization; Design optimization; Material distribution; Wave propagation problems; Inverse problems; Acoustic devices; Medical microwave tomography; High performance computing; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The increased knowledge about the complexity of the physiological processes increases the demand on the analytical techniques employed to explore them. A comprehensive analysis of the entire sample content is today the most common approach to investigate the molecular interplay behind a physiological deviation. LÄS MER

  4. 18. Co-rotational beam elements in instability problems

    Författare :Jean-Marc Battini; KTH; []
    Nyckelord :instability; co-rotational mehtod; branch-switching; beam element; warping; plastic buckling. post-bifurcation; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The purpose of the work presented in this thesis is to implement co-rotational beam elements and branch-switching procedures in order to analyse elastic and elastoplasticinstability problems. For the 2D beam elements, the co-rotational framework is taken from Crisfield [23]. LÄS MER

  5. 19. Continuity and Positivity Problems in Pseudo-differential Calculus

    Författare :Joachim Toft; Matematik (naturvetenskapliga fakulteten); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; funktionsanalys; fourieranalys; Serier; functional analysis; Fourier analysis; Series; Entropy.; Young s inequality; Twisted convolution; Schatten-von Neumann; Lower bounds; Weyl Calculus; Pseudo-differential Operqator; Continuity; Positivity;

    Sammanfattning : The paper deals with various positivity and continuity questions arising in the Weyl calculus of pseudo-differential operators. Let W be a symplectic vector space. LÄS MER

  7. 20. Solutions and their ambiguities for structure and motion problems

    Författare :Magnus Oskarsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surveying; navigation; autonomously guided vehicles; motion; Computer vision; structure; Mathematics; Matematik;

    Sammanfattning : This thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. LÄS MER
