  3. 22. Modelling of ultrasonic scattering from a crack in a pipe

    Författare :Jacob Rubenson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-Destructive Testing; Cylindrical Geometry; Pipe; Crack; Wave propagation;

    Sammanfattning : This thesis considers elastic wave scattering in an infinitely long cylindrical pipe with an infinitely long internal axial crack. The method used in this thesis is called a hypersingular integral equation method since it starts with an integral representation and by using the Green's tensor of the pipe it can be manipulated to a hypersingular equation for the crack-opening displacement (COD).

  4. 23. Orthogonal Polynomials, Operators and Commutation Relations

    Författare :John Musonda; Sergei Silvestrov; Sten Kaijser; Anatoliy Malyarenko; Natan Kruglyak; Irina Asekritova; Viktor Abramov; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : Orthogonal polynomials, operators and commutation relations appear in many areas of mathematics, physics and engineering where they play a vital role. For instance, orthogonal functions in general are central to the development of Fourier series and wavelets which are essential to signal processing. LÄS MER

  5. 24. En essä om estetisk efterrättelse

    Författare :Johanna Börrefors; Rättssociologiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Torgny T. Segerstedt; George Herbert Mead; GNU Linux; Aesthetics; Norms; Sociology of Law; Social Psychology; Sociologi;

    Sammanfattning : This thesis is about aesthetic observance. By these terms I intend to give an account of a social phenomenon considered an angle of approach on the understanding of norms. I narrow down the problems with the perspective from social psychology. The central claim by George Herbert Mead was that mind arises from human interaction. LÄS MER

  7. 25. En essä om estetisk efterrättelse

    Författare :Johanna Börrefors; Håkan Hydén; Carl-Göran Heidegren; Sweden Lund Lund University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Juridik; Law;

    Sammanfattning : Meads centrala påstående var att medvetandet uppstår mellan människor. Det individuella subjektet framträder därmed som en effekt. Jag har lyft fram det faktum att Miget - agenten snarare än subjektet - föregår och ingår i den sociala interaktionen. LÄS MER
