    University dissertation from Department of Mathematics, Uppsala University

    Author : Johanna Pejlare; Uppsala universitet.; Högskolan i Borås.; Chalmers tekniska högskola Göteborgs universitet.; Chalmers University of Technology University of Gothenburg.; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; MATHEMATICS; MATEMATIK; Mathematics; History of mathematics; axiomatization; intuition; visualization; images; Euclidean geometry; history of mathematics; euclidean geometry; matematikhistoria;

    Abstract : This dissertation deals with aspects of axiomatization, intuition and visualization in the history of mathematics. Particular focus is put on the end of the 19th century, before David Hilbert's (1862–1943) work on the axiomatization of Euclidean geometry. The thesis consists of three papers. READ MORE

  4. 4. Computational Modeling of Complex Flows

    University dissertation from Chalmers University of Technology

    Author : Johan Hoffman; Chalmers tekniska högskola Göteborgs universitet.; Chalmers University of Technology University of Gothenburg.; Göteborgs universitet.; Gothenburg University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MATEMATIK; MATHEMATICS; computational fluid dynamics; adaptive finite element method; a posteriori error estimate; subgrid modeling; transition to turbulence; multiresolution analysis; object-oriented software;

    Abstract : In this thesis we consider the following aspects of computational modeling of complex flows: (i) subgrid modeling, (ii) stability, (iii) a posteriori error estimation, and (iv) computational platform. <p />We develop a framework for adaptivity and error control for multiscale problems, in particular for turbulent flow, based on a posteriori error estimates.

  5. 5. Generalized Vandermonde matrices and determinants in electromagnetic compatibility

    University dissertation from Västerås : Mälardalen University

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : Matrices whose rows (or columns) consists of monomials of sequential powers are called Vandermonde matrices and can be used to describe several useful concepts and have properties that can be helpful for solving many kinds of problems. In this thesis we will discuss this matrix and some of its properties as well as a generalization of it and how it can be applied to curve fitting discharge current for the purpose of ensuring electromagnetic compatibility.
