  1. 1. VLSI aspects on inversion in finite fields

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Mikael Olofsson; Linköpings universitet.; Linköpings universitet.; [2002]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VLSI; Inversion; Finite Fields; Area; Delay; Power dissipation; Irreducible polynomials; Polynomial basis; Triangular basis; Normal basis; Dual basis; Tower fields.; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Different algorithms and architectures for inversion in finite extension fields are studied. The investigation is restricted to fields of characteristic two. Based on a simple transistor model, various architectures are compared with respect to delay, area requirement, and energy consumption. LÄS MER

    Detta är en avhandling från Göteborgs universitet

    Författare :Susanne Gustavsson; Högskolan i Skövde.; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES Social sciences Education; SAMHÄLLSVETENSKAP Socialvetenskap Pedagogik; Humanities and Social sciences; Humaniora-samhällsvetenskap; Teacher education; scientific basis; professional basis; field-based education; college-based education; critical hermeneutics; teacher education;

    Sammanfattning : Both historically and in our own time the teacher education has been discussed and changed to match current traditions and intentions. There is an ongoing debate about the scientifi c basis of teacher education and the relation to professional basis. LÄS MER

  3. 3. High Order Local Radial Basis Function Methods for Atmospheric Flow Simulations

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Lehto; Uppsala universitet.; Uppsala universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; meshless method; high order finite difference; atmospheric flow; hyper-viscosity; stable algorithm; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Since the introduction of modern computers, numerical methods for atmospheric simulations have routinely been applied for weather prediction, and in the last fifty years, there has been a steady improvement in the accuracy of forecasts. Accurate numerical models of the atmosphere are also becoming more important as researchers rely on global climate simulations to assess and understand the impact of global warming. LÄS MER

  4. 4. Gröbner Basis Methods for Minimal Problems in Computer Vision

    Detta är en avhandling från Centre for Mathematical Sciences, Lund University

    Författare :Henrik Stewenius; Lund University.; Lunds universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer vision; minimal problems; gröbner basis; Matematik; Teknik; Mathematics; Technological sciences;

    Sammanfattning : A method is presented for building solvers for classes of multivariate polynomial equations. The method is based on solving an analogous template problem over a finite field, and then using the elimination order established for this problem for the original class of problems. LÄS MER

  5. 5. Localised Radial Basis Function Methods for Partial Differential Equations

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Victor Shcherbakov; Uppsala universitet.; Uppsala universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; Partition of unity; Computational finance; Option pricing; Credit default swap; Glaciology; Fluid dynamics; Non-Newtonian flow; Anisotropic RBF; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : Radial basis function methods exhibit several very attractive properties such as a high order convergence of the approximated solution and flexibility to the domain geometry. However the method in its classical formulation becomes impractical for problems with relatively large numbers of degrees of freedom due to the ill-conditioning and dense structure of coefficient matrix.
