  1. 1. Hydromechanical simulations of wave energy conversion : Linear aspects

    Författare :Linnea Sjökvist; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Hydrodynamic simulations of buoy movement is crucial when designing a point absorbing wave power plant. The wave energy converter (WEC) that is developed in the Lysekil project by Uppsala University is studied in this thesis. LÄS MER

  2. 2. Piecewise Linear Control Systems

    Författare :Mikael Johansson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise quadratic functions; Linear matrix inequalities; Convex optimization; Optimal control; Performance analysis; Piecewise linear Lyapunov functions; Piecewise quadratic Lyapunov functions; Quadratic stability; Lyapunov stability; Piecewise linear systems; Nonlinear systems; Fuzzy systems; Hybrid systems.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : This thesis treats analysis and design of piecewise linear control systems. Piecewise linear systems capture many of the most common nonlinearities in engineering systems, and they can also be used for approximation of other nonlinear systems. LÄS MER

  3. 3. Grafisk och algebraisk representation : Gymnasieelevers förståelse av linjära funktioner

    Författare :Annika Pettersson; Igor Gachkov; Kerstin Pettersson; Lovisa Sumpter; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; mathematics education; linear function; graphic representation; scale; concept image; Matematik; Mathematics;

    Sammanfattning : This thesis concerns upper secondary students’ understanding of algebraic and graphic representation of linear functions. Components of the students’ concept images, so-called ‘concept elements’, were studied as a way to capture their understanding. LÄS MER

  4. 4. On the effects of structure and function on protein evolution

    Författare :Kristoffer Illergård; Arne Elofsson; Nir Ben-Tal; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; protein; structure; function; evolution; membrane; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Many proteins can be described as working machines that make sure that everything functions in the cell. Their specific molecular functions are largely dependent on their three-dimensional structures, which in turn are mainly predetermined by their linear sequences of amino acid residues. LÄS MER

  5. 5. Seasonal Adjustment and Dynamic Linear Models

    Författare :Can Tongur; Daniel Thorburn; Sune Karlsson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dynamic linear models; DLM; direct and indirect seasonal adjustment; relative efficiency; Huber loss function; Polls of polls; Wiener process; Swedish elections; statistik; Statistics;

    Sammanfattning : Dynamic Linear Models are a state space model framework based on the Kalman filter. We use this framework to do seasonal adjustments of empirical and artificial data. A simple model and an extended model based on Gibbs sampling are used and the results are compared with the results of a standard seasonal adjustment method. LÄS MER
