      The Shallow Water Equations model the fluid dynamics of deep ocean flow, and are used to simulate tides, tsunamis, and storm surges. Numerical solutions using finite difference methods are computationally expensive enough ...
    • Parallel Seismic Inversion for Shared Memory Systems 

      Hysing, Andreas Dreyer (Master thesis, 2010)
      In this thesis will explore how a scientific application forseismic inversion can take advantage of multi-core programming on x86 architecture. The thesis will focus on most effective domain divisions, communication patterns ...
    • Parallel Techniques for Estimation and Correction of Aberration in Medical Ultrasound Imaging 

      Herikstad, Åsmund (Master thesis, 2009)
      Medical ultrasound imaging is a great diagnostic tool for physicians because of its noninvasive nature. It is performed by directing ultrasonic sound into tissue and visualizing the echo signal. Aberration in the reflected ...
    • Parallelization of Artificial Spiking Neural Networks on the CPU and GPU 

      Vekterli, Tor Brede (Master thesis, 2009)
      Conventional artificial neural networks have traditionally faced inherent problems with efficient parallelization of neuron processing. Recent research has shown how artificial spiking neural networks can, with the ...
    • Parallelizing Particle-In-Cell Codes with OpenMP and MPI 

      Larsgård, Nils Magnus (Master thesis, 2007)
      Today's supercomputers often consists of clusters of SMP nodes. Both OpenMP and MPI are programming paradigms that can be used for parallelization of codes for such architectures. OpenMP uses shared memory, and hence is ...
    • Parameter-based online optimization in metric indexing using Bentley-Saxe transformations 

      Bakken, Jonas (Master thesis, 2021)
      Metrisk indeksering er et viktig verktøy for å kunne søke i store datamengder. Mange algoritmer og datastrukturer i dette feltet bruker en form for parameter i indekseringsprossessen. Det optimale valget for denne parameteren ...
    • Parametric Generation of Polygonal Tree Models for Rendering on Tessellation-Enabled Hardware 

      Nystad, Jørgen (Master thesis, 2010)
      The main contribution of this thesis is a parametric method for generation of single-mesh polygonal tree models that follow natural rules as indicated by da Vinci in his notebooks. Following these rules allow for a relatively ...
    • Part-of-Speech Tagging for Code-Mixed English-Hindi Twitter and Facebook Chat Messages
