    Sammanfattning : Protein-based materials, with their unique properties of combining high strength, while maintaining elasticity, and their inherent biocompatibility, hold immense potential for various applications. In order to harness these properties, we need to understand and control how protein building blocks come together to form hierarchically structured materials. LÄS MER

  3. 32. Approximation and Online Algorithms with Applications in Computational Biology and Computational Geometry

    Författare :Mia Persson; Data Vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; system; systems; control; Datalogi; numerical analysis; broadcasting; polygon exploration; robotics; Mathematics; Matematik; Computer science; clique partition; clustering; computational complexity; computational geometry; computational biology; online algorithm; kontroll; approximation algorithm;

    Sammanfattning : The main contributions of this thesis are in the area of approximation and online algorithm design and derivation of lower bounds on the approximability for a number of combinatorial optimization problems with applications in computational biology and computational geometry. Approximation and online algorithms are fundamental tools used to deal with computationally hard problems and problems in which the input is gradually disclosed over time. LÄS MER

  4. 33. Flow control and reduced-order modelling of transition in shear flows

  7. 35. Preattentive gaze control for robot vision

    Författare :Carl-Johan Westelius; Linköpings universitet; []
    Nyckelord :Robot vision; Resolution pyramids; Phase-based disparity estimation; Focus of attention; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A framework for a hierarchical approach to gaze control of a robot vision system is presented, and a implementation on a simulated robot is described. The robot is equipped with a heterogeneous sampled imaging system, a fovea, resembling the varying resolution in a human retina. LÄS MER
