  1. 11. Exact Results in Five-Dimensional Gauge Theories : On Supersymmetry, Localization and Matrix Models

    Författare :Anton Nedelin; Joseph Minahan; Ivan Kostov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetric localization; Matrix Models; Chern-Simons theory; Supersymmetric Field Theories; 2; 0 theories; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : Gauge theories are one of the corner stones of modern theoretical physics. They describe the nature of all fundamental interactions and have been applied in multiple branches of physics. The most challenging problem of gauge theories, which has not been solved yet, is their strong coupling dynamics. LÄS MER

    Sammanfattning : The cells of higher organisms exist in a complex protein network, the extracellular matrix (ECM), which has a wide variety of different components such as glycoproteins, proteoglycans and carbohydrates. As well as being the physical scaffold on which the cells are dependent for their positioning and mobility, the ECM exercises control over the cells, and changes in the matrix will affect the adhesion, proliferation and differentiation properties of these cells.

  5. 14. Skew-symmetric matrix pencils : stratification theory and tools

    Författare :Andrii Dmytryshyn; Bo Kågström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Investigating the properties, explaining, and predicting the behaviour of a physical system described by a system (matrix) pencil often require the understanding of how canonical structure information of the system pencil may change, e.g., how eigenvalues coalesce or split apart, due to perturbations in the matrix pencil elements.

  7. 15. Causal MMSE Filters for Personal Audio : A Polynomial Matrix Approach

    Författare :Simon Widmark; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Fredrik Gustafsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Audio; Audio Pre-compensators; Causal Filters; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This thesis is devoted to the study of synthesis of causal filters for generating personal sound zones. Personal sound zones, personal audio or personal sound is the theory and practice of steering sound in such a way that it is amplified in one region and suppressed in another. LÄS MER
