  1. 1. Om språkundervisning i mellanrummet - och talet om "kommunikation" och "kultur" i kursplaner och läromedel från 1962 till 2000

    Författare :Ulrika Tornberg; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; foreign language teaching and learning; culture; communication; contingent communicative action; democracy; discourse analysis; pragmatism; curriculum theory; Pedagogik; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : The overall aim of this study is to clarify the potential of foreign language teaching and learning to contribute to identity-formation and democracy as a real-time experience. Its focus is an analysis of how the current core concepts in foreign language teaching and learning within the Swedish school system, i.e. LÄS MER

  3. 2. Accurate quadrature and fast summation in boundary integral methods for Stokes flow

    Författare :Joar Bagge; Anna-Karin Tornberg; Katarina Gustavsson; Adrianna Gillman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Sammanfattning : This thesis concerns accurate and efficient numerical methods for the simulation of fluid flow on the microscale, known as Stokes flow or creeping flow. Such flows are important, for example, in understanding the swimming of microorganisms, spreading of dust particles, as well as in developing new nano-materials, and microfluidic devices that can be used for on-the-fly analysis of blood samples, among other things.

  4. 3. Spectral Accuracy in Fast Ewald Methods and Topics in Fluid Interface Simulation

    Författare :Dag Lindbo; Anna-Karin Tornberg; Michael S. Siegel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning :   This work contains two separate but related parts: one on spectrally  accurate and fast Ewald methods for electrostatics and viscous flow,  and one on micro- and complex fluid interface problems.  In Part I we are concerned with fast and spectrally accurate methods  to compute sums of slowly decaying potentials over periodic  lattices.

  5. 4. Integral equations and function extension techniques for numerical solution of PDEs

    Författare :Fredrik Fryklund; Anna-Karin Tornberg; Alex Barnett; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : Today many phenomena from science and engineering can be simulated accurately thanks to computational methods. Still, many challenges remain, one of them being close interface interactions when simulating e.g. the dynamics of a substance concentration in multiphase flows at the micro level. LÄS MER

  7. 5. Boundary integral methods for Stokes flow : Quadrature techniques and fast Ewald methods

    Författare :Oana Marin; Anna-Karin Tornberg; Anita Layton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boundary integral; Stokes flow; quadrature rule; Ewald decomposition;

    Sammanfattning : Fluid phenomena dominated by viscous effects can, in many cases, be modeled by the Stokes equations. The boundary integral form of the Stokes equations reduces the number of degrees of freedom in a numerical discretization by reformulating the three-dimensional problem to two-dimensional integral equations to be discretized over the boundaries of the domain.
