  1. 1. VLSI aspects on inversion in finite fields

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Mikael Olofsson; Christof Paar; [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

  2. 2. Motstånd och mening : Innebörd i blivande lärares seminariesamtal

    Detta är en avhandling från Göteborgs universitet

    Författare :Susanne Gustavsson; [2008]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Teacher education; scientific basis; professional basis; field-based education; college-based education; critical hermeneutics; SOCIAL SCIENCES Social sciences Education; SAMHÄLLSVETENSKAP Socialvetenskap Pedagogik; Humanities and Social sciences; Humaniora-samhällsvetenskap;

    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; Elisabeth Larsson; Natasha Flyer; Tobin Driscoll; [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. Global radial basis function collocation methods for PDEs

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ulrika Sundin; Elisabeth Larsson; Simon Hubbert; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Radial basis function (RBF) methods are meshfree, i.e., they can operate on unstructured node sets. Because the only geometric information required is the pairwise distance between the node points, these methods are highly flexible with respect to the geometry of the computational domain. LÄS MER

  5. 5. FEM and Scientific Visualisation as Tools in Furniture Design

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Pierre Olsson; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design process; Structural mechanics; Finite Element Method; case study; furniture; conceptual design; scientific visualisation;

    Sammanfattning : In the design process, knowledge of structural mechanics is often reduced to its use in determining whether the object that has been designed is sufficiently strong. Strength testing indicates this directly on a yes or no basis, whereas computations are able to quantify the degree of strength. LÄS MER
