  1. 1. Software tools for matrix canonical computations and web-based software library environments

    Author : Pedher Johansson; Bo Kågström; Erik. Elmroth; Alan Edelman; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Canonical structure; Jordan canonical form; controllability; StratiGraph; Matlab toolbox; Kronecker canonical form; matrix; matrix pencil; perturbation theory; closure hirerarchy; matrix stratification; control system; observability; Numerical analysis; Numerisk analys;

    Abstract : This dissertation addresses the development and use of novel software tools and environments for the computation and visualization of canonical information as well as stratification hierarchies for matrices and matrix pencils. The simplest standard shape to which a matrix pencil with a given set of eigenvalues can be reduced is called the Kronecker canonical form (KCF). READ MORE

    Abstract : Essay 1 studies the household's decision to supply labor and tests if the so-called unitary model holds. What is subject to a test is the resulting symmetry of the Slutsky matrix, i.e., that the compensated cross-wage effects are equal. READ MORE

  3. 3. Tools for Control System Design : Stratification of Matrix Pairs and Periodic Riccati Differential Equation Solvers

    Author : Stefan Johansson; Bo Kågström; Erik Elmroth; Paul Van Dooren; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; control system design; stratification; controllability; observability; matrix pair; canonical forms; linear quadratic regulator; periodic systems; periodic Riccati differential equation; Computer science; Datavetenskap; Numerical Analysis; numerisk analys;

    Abstract : Modern control theory is today an interdisciplinary area of research. Just as much as this can be problematic, it also provides a rich research environment where practice and theory meet. This Thesis is conducted in the borderline between computing science (numerical analysis) and applied control theory. READ MORE

  4. 4. Syndecan - Regulation and Function of its Glycosaminoglycan Chains

    Author : Anna S. Eriksson; Dorothe Spillmann; Catherine Merry; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heparan sulfate; chondroitin sulfate; integrin; cell motility; fibroblast growth factor signaling; pharyngeal cartilage; biosynthesis regulation; Medical Science; Medicinsk vetenskap;

    Abstract : The cell surface is an active area where extracellular molecules meet their receptors and affect the cellular fate by inducing for example cell proliferation and adhesion. Syndecans and integrins are two transmembrane molecules that have been suggested to fine-tune these activities, possibly in cooperation. Syndecans are proteoglycans, i.e. READ MORE

  5. 5. Molecular mechanisms in vascular inflammation

    Author : Peder S Olofsson; Karolinska Institutet; Karolinska Institutet; []

    Abstract : Vascular inflammation plays an important role in a multitude of major diseases including sepsis and atherosclerosis. Sepsis has been estimated to account for more than 100 000 deaths per year in Europe. READ MORE
