  1. 1. Conformational Stability!? Synthesis and Conformational Studies of Unnatural Backbone Modified Peptides

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anna S. Norgren; Uppsala universitet.; [2006]
    Nyckelord :Organic chemistry; Conformational investigations; β-peptides; glycosylation; biomolecular recognition; cyclic β³-peptides; cyclic mixed α β²-peptides; β-peptoids; Organisk kemi;

    Sammanfattning : The beauty of the wide functionality of proteins and peptides in Nature is determined by their ability to adopt three-dimensional structures. This thesis describes artificial molecules developed to mimic secondary structures similar to those found crucial for biological activities. LÄS MER

  3. 3. Stability of Low-Frequency AC Railways Models and Transient Stability

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :John Laury; Lars Abrahamsson; Math Bollen; Pablo Arboleya; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : Low-frequency AC railway grids are unique in the sense that a only few countries around the world uses them, still however, they are an important parts of their countries infrastructures. Due to the usage of a dierent frequency than the public grid of the country, conversion of frequency is needed for the interconnection. LÄS MER

  4. 4. Global stability and feedback control of boundary layer flows

    Detta är en avhandling från Stockholm : KTH

    Författare :Espen Åkervik; Dan S. Henningson; Luca Brandt; Dwight Barkley; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stability; Global Stability; Feedback Control; Control; Estimation; Absolute Convective Instabilities; Model Reduction; TECHNOLOGY Engineering mechanics Fluid mechanics; TEKNIKVETENSKAP Teknisk mekanik Strömningsmekanik;

    Sammanfattning : In this thesis the stability of generic boundary layer flows is studied from a global viewpoint using optimization methods. Global eigenmodes of the incompressible linearized Navier-Stokes equations are computed using the Krylov subspace Arnoldi method. LÄS MER

  5. 5. Analysis and Design of Hybrid Systems

    Detta är en avhandling från Stockholm : KTH

    Författare :Stefan Pettersson; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asymptotic stability; Lyapunov theory; exponential stability; piecewise quadratic Lyapunov functions; hybrid systems; stability; linear matrix inequalities; nonlinear systems; LMIs; control theory; fuzzy systems;

    Sammanfattning : Many physical systems today are modeled by interacting continuous and discrete event systems. Such hybrid systems contain both continuous and discrete states that influence the dynamic behavior. LÄS MER
