  1. 1. Idioms Unlimited. A study of non-canonical forms of English verbal idioms in the British National Corpus

    Författare :Elisabeth Gustawsson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; English; idiom; corpus; transparency; isomorphicity; modification; derivation; permutation; non-canonical; figurative;

    Sammanfattning : The study is a corpus-based investigation of the semantic, lexical, and grammatical flexibility of English verbal idioms, focusing on qualitative analyses of examples of current British English usage. 300 verbal idioms - i.e. idioms that consist of a verb and a complement, e.

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

    Författare :Stefan Johansson; Bo Kågström; Erik Elmroth; Paul Van Dooren; Umeå universitet; []
    Nyckelord :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;

    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

  4. 3. Non-canonical ATG8 conjugation in ESCRT-driven membrane remodeling processes

    Författare :Anastasia Knyazeva; Yao-Wen Wu; Richard Lundmark; Sascha Martens; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATG8 conjugation; Endosomal Sorting Complex Required for Transport; membrane remodeling; chemical genetics;

    Sammanfattning : ATG8 family proteins have the unique ability to conjugate to membrane lipids. Initially identified as a hallmark of autophagy, ATG8 lipidation is emerging as an important regulator of a growing list of non-degradative cellular functions. LÄS MER

  5. 4. Multipoint Okounkov bodies, strong topology of ω-plurisubharmonic functions and Kähler-Einstein metrics with prescribed singularities

    Författare :Antonio Trusiani; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Okounkov bodies; Seshadri constant; Kähler-Einstein metrics; Kähler Geometry; Canonical metrics; Fano manifolds; Pluripotential theory; Complex Monge-Ampère equations; Kähler packing;

    Sammanfattning : The most classical topic in Kähler Geometry is the study of Kähler-Einstein metrics as solution of complex Monge-Ampère equations. This thesis principally regards the investigation of a strong topology for ω-plurisubharmonic functions on a fixed compact Kähler manifold (X,ω), its connection with complex Monge-Ampère equations with prescribed singularities and the consequent study of singular Kähler-Einstein metrics.

  7. 5. 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.
