  • Vasdal, Thomas Arneberg (Master thesis, 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 ...
  • Nordhaug, Hans Fredrik; Celia, Michael A.; Dahle, Helge K. (Journal article; Peer reviewed, 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 ...
  • Xi, Linda Mon (Master thesis, 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 ...
  • Brun, Knut-Erland (Master thesis, 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 ...
  • Socquet-Juglard, Hervé; Dysthe, Kristian; Trulsen, Karsten; Krogstad, Harald E.; Liu, Jingdong (Journal article; Peer reviewed, Cambridge University Press, 2005-11)
  • Hana, Gert Monstad (Master thesis, The University of Bergen, 2002)
  • Autenried, Christian (Doctoral thesis, The University of Bergen, 2015-02-13)
  • Olsen, Håvard Goodwin (Master thesis, 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 ...
  • Birkeland, Tore (Doctoral thesis, The University of Bergen, 2009-12-18)
  • Bergo, Brede Rem (Master thesis, 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 ...
  • Nicolajsen, Tomas (Master thesis, 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 ...
  • Sævik, Pål Næverlid (Master thesis, 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 ...
  • Wan, Min; Wang, Yu; Bae, Egil; Tai, Xue-Cheng; Wang, Desheng (Preprint, 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 ...
  • Schei, Ole Johan Sørensen (Master thesis, The University of Bergen, 2009-09-15)
  • Johansson, Kari (Master thesis, The University of Bergen, 2014-06-06)
    Problemstillinga i oppgåva var korleis opplever elevane bruk av rekneark i matematikk på ungdomstrinnet. Gjennom eitt år vart ulike reknearkoppgåver prøvd ut i 9./10. klasse. I etterkant henta eg inn data ved hjelp av ...
  • Rabenorolahy, Lalaniaina David (Master thesis, The University of Bergen, 2008)
  • Schwinger, Eyram A. Kojo (Master thesis, The University of Bergen, 2009-06-02)
    This study is aimed at testing the use of Magnetic Resonance (MR) images and mathematical models for renal parameter estimation. The study was based on four models; the Patlak model, Cortical Compartment model, Separable ...
  • Lyyjynen, Hannu Sakari (Master thesis, The University of Bergen, 2014-03-10)
    The history of MCMC, theories of Bayesian thinking and model choice, the Accept- Reject-algorithm, Markov chains, the Metropolis- Hastings-algorithm and the reversible jump MCMC are explained. Then the reversible ...
  • Celia, Michael A.; Nordbotten, Jan Martin; Bachu, Stefan; Dobossy, Mark E.; Court, Benjamin (Journal article, Elsevier, 2009-02)
    One of the outstanding challenges for large-scale CCS operations is to develop reliable quantitative risk assessments with a focus on leakage of both injected CO2 and displaced brine. A critical leakage pathway is associated ...
