  1. 1. On Identification of Biological Systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Egi Hidayat; Uppsala universitet.; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; biomedical systems; insect vision; endocrine systems; orthogonal basis functions; time delay; impulse response; Laguerre functions; Laguerre polynomials; excitation design; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : System identification finds nowadays application in various areas of biological research as a tool of empiric mathematical modeling and model individualization. A fundamental challenge of system identification in biology awaits in the form of response variability. READ MORE

  2. 2. Topics on Harmonic analysis and Multilinear Algebra

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mahdi Hormozi; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Generalized bounded variation; Helly s theorem; Modulus of variation; Generalized Wiener classes; Symmetry classes of tensors; Orthogonal basis; Brauer symmetry classes of tensors; Multilinear singular integrals; weighted norm inequalities; weighted bounds; local mean oscillation; Lerner s formula;

    Abstract : The present thesis consists of six different papers. Indeed, they treat three different research areas: function spaces, singular integrals and multilinear algebra. In paper I, a characterization of continuity of the $p$-$\Lambda$-variation function is given and Helly's selection principle for $\Lambda BV^{(p)}$ functions is established. READ MORE

  3. 3. Vehicle wakes subject to side wind conditions

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Magnus Urquhart; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drag; surrogate model; cavity; Latin Hypercube Sampling; wake; aerodynamics; real world conditions; Proper Orthogonal Decomposition; wind averaged drag; Radial Basis Functions; side wind; optimization; tapered extensions; cycle averaged;

    Abstract : Passenger vehicles are associated with travel flexibility, today it is clear that this flexibility impacts the environment. Passenger vehicles account for more than one-tenth of all greenhouse gasses in Europe with approximately a quarter of the vehicle's energy consumption wasted as aerodynamic drag. READ MORE

  4. 4. A generalized finite element method for linear thermoelasticity

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Anna Persson; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermoelasticity; parabolic equations; linear elasticity; multiscale; composites; generalized finite element; local orthogonal decomposition; a priori analysis;

    Abstract : In this thesis we develop a generalized finite element method for linear thermoelasticity problems, modeling displacement and temperature in an elastic body. We focus on strongly heterogeneous materials, like composites. READ MORE
