    • The Seismic Analyzer: Interpreting and Illustrating 2D Seismic Data 

      Patel, Daniel; Giertsen, Christopher; Thurmond, John; Gjelberg, John; Gröller, Eduard (Peer reviewed; Journal article, 2008)
      We present a toolbox for quickly interpreting and illustrating 2D slices of seismic volumetric reflection data. Searching for oil and gas involves creating a structural overview of seismic reflection data to identify ...

    • Similarity-based Exploded Views 

      Ruiz, Marc; Viola, Ivan; Boada, Imma; Bruckner, Stefan; Feixas, Miquel; Sbert, Mateu (Lecture Notes in Computer Science; 5166, Chapter; Peer reviewed, 2008)
      Exploded views are often used in illustration to overcome the problem of occlusion when depicting complex structures. In this paper, we propose a volume visualization technique inspired by exploded views that partitions ...

    • Comparison of Solving Techniques for Non-linear Sparse Equations over Finite Fields with Application in Cryptanalysis 

      Schilling, Thorsten Ernst (Master thesis, 2008)
      The work on this thesis gives a summary of the Gluing/Agreeing techniques, as well as a reference implementation of this methods. Furthermore widely used SAT-solving techniques are explained and a short insight to the ...

    • Improving Efficiency in Parameter Estimation Using the Hamiltonian Monte Carlo Algorithm 

      Alfaki, Mohammed (Master thesis, 2008)
      This thesis investigates three approaches to improve the performance of the Hamiltonian Monte Carlo algorithm. The first approach enhances the Hamiltonian Monte Carlo by suppressing random walk in the Gibbs sampling using ...

    • Naturlige nettverk 

      Vatshelle, Martin (Master thesis, 2008)
      En innføring i naturlige nettverk. Vi forklarer og diskuterer begrepet naturlige nettverk og vurderer hvilke nettverk som bør kalles naturlige. Vi ser på forskjeller og likheter mellom tilfeldige, planlagte og naturlige ...
