    • Parallel Algorithms for Neuronal Spike Sorting 

      Bergheim, Thomas Stian; Skogvold, Arve Aleksander Nymo (Master thesis, 2011)
      Neurons communicate through electrophysiological signals, which may be recorded using electrodes inserted into living tissue.When a neuron emits a signal, it is referred to as a spike, and an electrode can detect these ...
    • 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 ...
    • Parallel Methods for Projection on Strongly Curved Surfaces 

      Chelliah, Joel Eelaraj (Master thesis, 2011)
      Using the parallel architecture of the graphics processing unit for general purpose programming has become increasingly common in the recent years. The process of creating a mathematically correct transformation of a scene ...
    • Parallel Methods for Real-Time Visualization of Snow 

      Saltvik, Ingar (Master thesis, 2006)
      Using computer generated imaging is becoming more and more popular in areas such as computer gaming, movie industry and simulation. A familiar scene in the winter months for most us in the Nordic countries is snow. This ...
    • Parallel query evaluation on multicore architectures 

      Lilleengen, Ulf (Master thesis, 2010)
      Multicore processors are common in server systems sold today. Writingapplication software that takes advantage of such systems, not to mentionadopting existing software to the parallel domain, is complex. Workloads such ...
    • 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 ...
    • 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 ...
    • Particle-based Powder-snow Avalanche Simulation Using GPU 

      Yndestad, Leif Kåre Hornnes (Master thesis, 2011)
      The main focus of this thesis was the simulation of a powder-snow avalanche flow. The simulation were implemented using the particle-based simulation solution SPH, from a mathematical model describing powder-snow flow ...
    • Partitioning an Open Source Database in the Cloud 

      Ostvold, Even (Master thesis, 2014)
      Cloud computing has become a part of how web applications are being developed. Theeasy access to virtually endless supply of servers that the cloud provides has brought manybenefits, but at the precondition that the ...
    • Partitioning an Open Source Database in the Cloud 

      Østvold, Even (Master thesis, 2014)
      Cloud computing has become a part of how web applications are being developed. The easy access to virtually endless supply of servers that the cloud provides has brought many benefits, but at the precondition that the ...
    • Part-of-Speech Tagging for Code-Mixed English-Hindi Twitter and Facebook Chat Messages
