    Sammanfattning : The aim of this study is to examine the semantic architecture of the motif complex the four elements, i.e. fire, air, water and earth, in the Swedish poet Gunnar Ekelöf’s poem A Mölna Elegy (1960). The poem belongs to the same polyphonic and quotative-allusive tradition as T. LÄS MER

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

    Detta är en avhandling från Umeå : Print & Media, Umeå universitet

    Författare :Stefan Johansson; Umeå universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; control system design; stratification; controllability; observability; matrix pair; canonical forms; linear quadratic regulator; periodic systems; periodic Riccati differential equation; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Numerical Analysis; numerisk analys;

    Sammanfattning : 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. LÄS MER
