    • Statistiske modelleringer i det europeiske gassmarkedet 

      Frontéri, Anette Ullestad (The University of Bergen, 2015-06-01)
      I denne oppgaven studerer vi naturgassmarkedet i Europa. Først ser vi på hvilke forhold som påvirker gassprisen. Deretter studerer vi statistisk teori om tidsrekker, volatilitet og copula. Til slutt blir det gjort ...

    • Stochastic chain-ladder models in nonlife insurance 

      Gould, Ingrid Langfeldt (The University of Bergen, 2008)
      This thesis examines the stochastic models which reproduce chain-ladder estimates used in reserve estimation for nonlife insurance. The chain-ladder method provides no information regarding the variability of the outcome, ...

    • Stochastic unit-root processes 

      Dyrhovden, Sigve Brix (The University of Bergen, 2016-06-01)
      In practice there are many types of processes that have near unit roots and are very difficult to distinguish from standard unit-root processes, given a finite sample. In our thesis we study a particular class of such ...

    • Streamline based History Matching 

      Sandve, Tor Harald (The University of Bergen, 2009-05-07)
      Streamline based reservoir simulation has been used with great success in the petroleum industry for decades. Fast computational speed together with the fact that sensitivities can be computed analytically along streamlines ...

    • A Streamline Front Tracking Method for Two- and Three-Phase Flow Including Capillary Forces 

      Berre, Inga; Dahle, Helge K.; Karlsen, Kenneth Hvistendahl; Nordhaug, Hans Fredrik (American Mathematical Society, 2002)
    • Streamline methods for parabolic differential equations. 

      Hafver, Jørn (The University of Bergen, 2008)
      Parabolic advection-diffusion equations arise when modelling flow in porous media. We will in this thesis discuss two different problem set-ups from which these types of equations arise. - Groundwater contamination with ...

    • Streamline Tracing on Irregular Grids 

      Hægland, Håkon (The University of Bergen, 2003)
      Master thesis
    • A study in the effects of different treatments on the growth of high fluorescence virus. 

      Maharjan, Bikram (The University of Bergen, 2011-09-01)
      Master thesis
    • A study in Univalence 

      Husebø, Anders Knarvik (The University of Bergen, 2014-06-02)
      In this master thesis we want to study the newly discovered homotopy type theory, and its models within mathematics. We look at models in simplicial sets, simplicial symmetric monoids, and a new category which could be ...

    • A Study on Continuous Max-Flow and Min-Cut Approaches 

      Yuan, Jing; Bae, Egil; Tai, Xue-Cheng (IEEE, 2010)
      We propose and investigate novel max-flow models in the spatially continuous setting, with or without supervised constraints, under a comparative study of graph based max-flow / min-cut. We show that the continuous max-flow ...

    • A study on iterative methods for Richards' equation 

      List, Florian; Radu, Adrian Florin (Springer, 2016-04)
      This work concerns linearization methods for efficiently solving the Richards equation, a degenerate elliptic-parabolic equation which models flow in saturated/unsaturated porous media. The discretization of Richards’ ...

    • Sub-Riemannian geometry of spheres and rolling of manifolds 

      Molina, Mauricio Godoy (The University of Bergen, 2011-04-29)
      Doctoral thesis
    • Sub-semi-Riemannian geometry on Heisenberg-type groups

      Doctoral thesis
    • Subsea pump vibration analysis for predictive maintenance 

      Rouzbahaneh, Mahdi (The University of Bergen, 2015-11-29)
      The goal of this study is to compare vibration signals of subsea pumps from two different time periods. These signals are gathered for predictive maintenance reasons. Vibration analysis is one of the most efficient tools ...

    • Supervised Continuous Max-flow for Segmentation of Images with Intensity Inhomogeneities 

      Guo, Junjie (The University of Bergen, 2016-05-26)
      In this thesis we propose a regional adaptive active contour model for segmenting images with intensity inhomogeneities effectively. This model includes a regularization term, a global energy term and a local energy ...

    • Surface reconstruction Using Probability Based Photo-Consistency 

      Kjørstad, Åsmund (The University of Bergen, 2009-12-04)
      We reconstruct the surface of an object seen from many different angles. We construct an energy functional by using visibility constraints and photo-consistency. This is then solved by the piecewise constant level set method.

    • Survey strategies to quantify and optimize detecting probability of a CO2 seep in a varying marine environment 

      Hvidevold, Hilde Kristine; Alendal, Guttorm; Johannessen, Truls; Ali, Alfatih Omer Mohammed Ahmed (Elsevier, 2016-09)
      Designing a marine monitoring program that detects CO2 leaks from subsea geological storage projects is challenging. The high variability of the environment may camouflage the anticipated anisotropic signal from a leak and ...
