    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Finite Element Methods; GPU; Matrix-Free; Multigrid; Transactional Memory; Scientific Computing; Beräkningsvetenskap;

    Abstract : In this thesis, techniques for efficient utilization of modern computer hardwarefor numerical simulation are considered. In particular, we study techniques for improving the performance of computations using the finite element method. READ MORE

  4. 12. On Prism-based Motion Blur and Locking-proof Tetrahedra

    Author : Mads Rönnow; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; continuous collision detection; locking; GPU; parallel; real time; FEM; motion blur; prism;

    Abstract : Motion blur is an important visual effect in computer graphics for both real-time, interactive, and offline applications. Current methods offer either slow and accurate solutions for offline ray tracing applications, or fast and inaccurate solutions for real-time applications. READ MORE

  5. 13. Mesoscopic thin film superconductors - A computational framework

    Author : Mikael Håkansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Riccati equation; quasiclassical theory; simulation; GPU; time-reversal symmetry; CUDA; Eilenberger equation; coherence functions; Superconductivity; computational;

    Abstract : Motivated by experiments on superconductors in the microscopic regime and the realization of small superconducting devices such as qubits, we initiate a computational project in the form of a numerical simulation package to model and predict the behavior of these type of systems. It is a multidisciplinary endeavor in that it employs theory, computational science, software design, and to some extent new visualization techniques. READ MORE

  6. 14. Efficient GPU-based Image Registration : for Detailed Large-Scale Whole-body Analysis

    Author : Simon Ekström; Robin Strand; Filip Malmberg; Joel Kullberg; Håkan Ahlström; Fred Hamprecht; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; Image registration; whole-body; Radiology; Radiologi;

    Abstract : Imaging has become an important aspect of medicine, enabling visualization of internals in a non-invasive manner. The rapid advancement and adoption of imaging techniques have led to a demand for tools able to take advantage of the information that is produced. READ MORE

  7. 15. Fast Radon Transforms and Reconstruction Techniques in Seismology

    Author : Viktor Nikitin; Matematik LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fourier transform FFT ; Radon transforms; GPU;

    Abstract : The measurements conducted in tomography and seismology typically yield large multidimensional data sets. This in combination with the fact that the data may have an irregular structure makes it computationally prohibitive to use simple reconstruction methods directly. READ MORE
