  2. 1. High Performance Adaptive Finite Element Methods : With Applications in Aerodynamics

    Author : Niclas Jansson; Johan Hoffman; Johan Jansson; Vincent Heuveline; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The massive computational cost for resolving all scales in a turbulent flow makes a direct numerical simulation of the underlying Navier-Stokes equations impossible in most engineering applications. Recent advances in adaptive finite element methods offer a new powerful tool in Computational Fluid Dynamics (CFD). READ MORE

  4. 2. High performance adaptive finite element methods for turbulent fluid flow

    Author : Niclas Jansson; Johan Hoffman; Sverker Holmgren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

    Abstract : Understanding the mechanics of turbulent fluid flow is of key importance for industry and society as for example in aerodynamics and aero-acoustics. The massive computational cost for resolving all turbulent scales in a realistic problem makes direct numerical simulation of the underlying Navier-Stokes equations impossible. READ MORE

  5. 3. Violence through the life cycle : A public health problem

    Author : Niclas Olofsson; Kent Lindqvist; Ingela Danielsson; Staffan Jansson; Linköpings universitet; []
    Keywords : ;

    Abstract : Background: Violence has probably always been part of the human experience. Its impact can be seen, in various forms, in all parts of the world. In 1996, WHO:s Forty-Ninth World Health Assembly adopted a resolution , declaring violence a major and growing public health problem around the world. READ MORE

  6. 4. Leveraging Intermediate Representations for High-Performance Portable Discrete Fourier Transform Frameworks : with Application to Molecular Dynamics

    Author : Måns Andersson; Stefano Markidis; Artur Podobas; Niclas Jansson; Ivy Bo Peng; Hartwig Anzt; KTH; []
    Keywords : Intermediate Representation; Discrete Fourier Transform; Fast Fourier Transform; Molecular Dynamics; Mellankod; diskret Fouriertransform; snabb Fouriertransform; Molekyldynamik;

    Abstract : The Discrete Fourier Transform (DFT) and its improved formulations, the Fast Fourier Transforms (FFTs), are vital for scientists and engineers in a range of domains from signal processing to the solution of partial differential equations.  A growing trend in Scientific Computing is heterogeneous computing, where accelerators are used instead or together with CPUs.
