  2. 21. Parameter estimation in heterogeneous catalysis

    Author : Jonas Sjöblom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microkinetic modelling; Jacobian; Parameter estimation; Latent Variable models; Design of experiments; heterogeneous catalysis; sensitivity analysis; Experimental design;

    Abstract : The detailed modelling of heterogeneous catalytic systems is challenging due to the unknown nature of new catalytic materials as well as the often required transient nature of the resulting models. Thus, this thesis deals with the methodologies involved in the kinetic modelling of heterogeneous catalysis and in particular NOx reduction systems. READ MORE

  4. 22. Mathematical models of biological interactions

    Author : Linnéa Gyllingberg; David J.T. Sumpter; Kolbjörn Tunström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Mathematical models are used to describe and analyse different types of biological interactions.  From self-propelled particle models capturing the collective motion of fish schools to models in mathematical neuroscience describing the interactions between neurons to individual-based models of ecological interactions.

  5. 23. Quantum Computing for Airline Planning and Operations

    Author : Marika Svensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; quantum technology;

    Abstract : Classical algorithms and mathematical optimization techniques have been used extensively by airlines to optimize their profit and ensure that regulations are followed. In this thesis, we explore which role quantum algorithms can have for airlines. READ MORE

  6. 24. Computational electromagnetics : software development and high frequency modeling of surface currents on perfect conductors

    Author : Sandy Sefi; Jesper Oppelstrup; Francisco Saez de Adana; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High frequency approximations; Maxwell’s equations; Method of Moments; Physical Optics; Geometrical Theory of Diffraction; Extraction Extrapolation; Numerical analysis; Numerisk analys;

    Abstract : In high frequency computational electromagnetics, rigorous numerical methods be come unrealistic tools due to computational demand increasing with the frequency. Instead approximations to the solutions of the Maxwell equations can be employed to evaluate th electromagnetic fields. READ MORE

  7. 25. Permanence of age-structured populations in a spatio-temporal variable environment

    Author : Sonja Radosavljevic; Vladimir Kozlov; Uno Wennergren; Bengt-Ove Turesson; Michael Chipot; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : It is widely recognized that various biotic and abiotic factors cause changes in the size of a population and its age distribution. Population structure, intra-specific competition, temporal variability and spatial heterogeneity are identified as the most important factors that, alone or in combination, influence population dynamics.
