    • Passer og linjal, origami og Galoisteori 

      Vasdal, Thomas Arneberg (The University of Bergen, 2011-06-01)
      Denne oppgaven prøver å belyse konstruksjoner med passer og linjal og origami ved hjelp av Galois- teori. De tre klassiske problemene: Kubens fordobling, sirkelens kvadratur og vinkelens tredeling er sentrale. Oppgaven er ...

    • A pore network model for calculation of interfacial velocities 

      Nordhaug, Hans Fredrik; Celia, Michael A.; Dahle, Helge K. (Elsevier Science, 2003)
      Two-phase flow in porous media is characterized by fluid-fluid interfaces that separate the fluid phases at the pore scale. These interfaces support pressure differences between phases, and their dynamics allow for ...

    • Portfolio Optimization with PCC-GARCH-CVaR model 

      Xi, Linda Mon (The University of Bergen, 2014-06-02)
      This thesis investigates the Conditional Value-at-Risk (CVaR) portfolio optimization approach combined with a univariate GARCH model and pair-copula constructions (PCC) to determine the optimal asset allocation for a ...

    • Post-lie algebras and isospectral flows 

      Ebrahimi-Fard, Kurusch; Lundervold, Alexander; Mencattini, Igor; Munthe-Kaas, Hans (National Academy of Science of Ukraine, 2015-11-20)
      In this paper we explore the Lie enveloping algebra of a post-Lie algebra derived from a classical R-matrix. An explicit exponential solution of the corresponding Lie bracket flow is presented. It is based on the solution ...

    • Potensialet for dyp geotermisk energi i Norge: Modellering av varmeutvinning fra konstruerte geotermiske system 

      Brun, Knut-Erland (The University of Bergen, 2010-10-05)
      Dette prosjektet tar for seg to ulike modeller for et konstruert geotermisk system; et lukket enkeltbrønn-system og et åpent, sprekkdominert system. Enkeltbrønn-systemet er modellert eksplisitt, og modellen er også tilpasset ...

    • Punktprosessmodeller for linjetransektdata 

      Olsen, Håvard Goodwin (The University of Bergen, 2010-04-27)
      Oppgaven omhandler punktprosesser som modell for observasjoner ved en transektlinje. Hovedprosessen er en Markovmodulert Poissonprosess som tillater at punkter opptrer oftere i noen perioder enn andre, den er her begrenset ...

    • Quality of the Analysis Step in EnKF 

      Bergo, Brede Rem (The University of Bergen, 2011-06-15)
      In many physical applications we want to characterize the parameters of a system based on indirect observations or measurements. In a reservoir simulator setting, the goal is to simulate the production of hydrocarbons ...

    • Radielle basisfunksjoner som adaptiv kollokasjonsmetode 

      Nicolajsen, Tomas (The University of Bergen, 2014-06-01)
      Hensikten med oppgaven er å undersøke en adaptiv kollokasjonsmetode basert på radielle basisfunksjoner. Målet er å finne ut om man med enkle kriterier for senter- og formparameterfordelingen kan oppnå en fordeling ...

    • Reactive Transport in Porous Media 

      Sævik, Pål Næverlid (The University of Bergen, 2011-08-01)
      In this thesis, we show how the common equations for flow in porous media can be expanded to account for geochemical reactions. Furthermore, the complications arising when solving the new equations numerically are described ...

    • Reconstructing Open Surfaces via Graph-Cuts 

      Wan, Min; Wang, Yu; Bae, Egil; Tai, Xue-Cheng; Wang, Desheng (The authors, 2011)
      A novel graph-cuts-basedmethod is proposed for reconstructing open surfaces from unordered point sets. Through a boolean operation on the crust around the data set, the open surface problem is translated to a watertight ...
    • Regresjonsmodeller i skipsforsikring 

      Schei, Ole Johan Sørensen (The University of Bergen, 2009-09-15)
