  1. 1. A theoretical investigation of Tin+1AlCn and Mn2GaC MAX phases : phase stability and materials properties

    Författare :Andreas Thore; Johanna Rosén; Björn Alling; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents theoretical research on MAX phases (M=transition metal, A=A-group element, X=carbon and/or nitrogen), with focus on predictions of phase stability as well as of physical properties.The first part is an investigation of the phase stability of the MAX phases Ti2AlC, Ti3AlC2, and Ti4AlC3 at elevated temperatures, where the former two phases have been obtained experimentally.

  2. 2. Phase stability and physical properties of nanolaminated materials from first principles

    Författare :Andreas Thore; Johanna Rosén; Björn Alling; Martin Dahlqvist; Tilmann Hickel; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The MAX phase family is a set of nanolaminated, hexagonal materials typically comprised of three elements: a transition metal (M), an A-group element (A), and carbon and/or nitrogen (X). In this thesis, first-principles based methods have been used to investigate the phase stability and physical properties of a number of MAX and MAX-like phases. LÄS MER

  3. 3. Juridifiering som demokratiseringsprocess? : Fallet likabehandling i svensk skola

    Författare :Maria Rosén; Andreas Bergh; Emma Arneback; Sara Irisdotter Aldenmyr; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Juridification; democratization; education; equal treatment; The Child and School Student Protection Act; abduction; Juridifiering; demokratisering; utbildning; likabehandling; Barn- och elevskyddslagen; abduktion; Pedagogik; Education;

    Sammanfattning : The relationship between education and democracy has long attracted political interest. This thesis takes an interest in the political initiative to democratize education through legal means. This initiative is viewed as a wider national and global societal phenomenon. LÄS MER

  4. 4. The Double Layer Potential Operator Through Functional Calculus

    Författare :Michail Krimpogiannis; Andreas Rosén; Bengt-Ove Turesson; Kaj Nyström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Layer potential operators associated to elliptic partial differential equations have been an object of investigation for more than a century, due to their contribution in the solution of boundary value problems through integral equations.In this Licentiate thesis we prove the boundedness of the double layer potential operator on the Hilbert space of square integrable functions on the boundary, associated to second order uniformly elliptic equations in divergence form in the upper half-space, with real, possibly non-symmetric, bounded measurable coefficients, that do not depend on the variable transversal to the boundary.
