  1. 11. Efficient Adaptive Algorithms for an Electromagnetic Coefficient Inverse Problem

    Författare :John Bondestam Malmberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coefficient inverse problem; inverse scattering; Maxwell’s equations; approximate global convergence; finite element method; adaptivity; ; a posteriori error analysis;

    Sammanfattning : This thesis comprises five scientific papers, all of which are focusing on the inverse problem of reconstructing a dielectric permittivity which may vary in space inside a given domain. The data for the reconstruction consist of time-domain observations of the electric field, resulting from a single incident wave, on a part of the boundary of the domain under consideration. LÄS MER

  3. 12. The construction, analysis and validation of mechanistic mathematical models of protein kinetics in the context of replicative ageing in budding yeast

    Författare :Johannes Borgqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein kinetics; Replicative ageing; Cdc42; Ordinary differential equations; Reaction diffusion models; Parameter estimation; Model validation; Model construction; Symmetry methods;

    Sammanfattning : Mathematical modelling constitutes a forceful tool for elucidating properties of biological systems. Using theoretical approaches in combination with experimental techniques it is possible to study specific molecular aspects of phenomena such as the ageing of human beings. LÄS MER

  4. 13. Statistical modelling and analyses of DNA sequence data with applications to metagenomics

    Författare :Mariana Buongermino Pereira; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; generalised hidden Markov models; gene abundance data; metagenomics; statistical modelling; bioinformatics; normalisation; DNA sequence data; bioinformatics;

    Sammanfattning : Microorganisms are organised in complex communities and are ubiquitous in all ecosystems, including natural environments and inside the human gut. Metagenomics, which is the direct sequencing of DNA from a sample, enables studying the collective genomes of the organisms that are there present. LÄS MER

  5. 14. Contributions to the theory of optimal stopping

    Författare :Sören Christensen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with the explicit solution of optimal stopping problems with infinite time horizon. To solve Markovian problems in continuous time we introduce an approach that gives rise to explicit results in various situations. LÄS MER
