    • PDE Based Algorithms for Smooth Watersheds 

      Hodneland, Erlend; Tai, Xue-Cheng; Kalisch, Henrik (IEEE, 2016-04)
      Watershed segmentation is useful for a number of image segmentation problems with a wide range of practical applications. Traditionally, the tracking of the immersion front is done by applying a fast sorting algorithm. In ...

    • Persistent Homology via Quotient Spaces 

      Truong, Tam Thanh (The University of Bergen, 2017-12-20)
      A point cloud can be endowed with a topological structure by constructing a simplicial complex using the points as vertices. Instead of assigning a single simplicial complex, Topological Data Analysis (TDA) employs multiple ...

    • 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 ...

    • Postinjection Normal Closure of Fractures as a Mechanism for Induced Seismicity 

      Ucar, Eren; Berre, Inga; Keilegavlen, Eirik (American Geophysical Union, 2017-10-04)
      Understanding the controlling mechanisms underlying injection-induced seismicity is important for optimizing reservoir productivity and addressing seismicity-related concerns related to hydraulic stimulation in Enhanced ...

    • 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 ...

    • Problemløsning i norske og russiske matematikklærebøker for videregående skole. En sammenlignende studie av eksempler i norske og russiske lærebøker 

      Aaseth, Natalia (The University of Bergen, 2016-01-17)
      Denne masteroppgaven sammenligner lærebøkene fra to land, Norge og Russland, i emneområder Algebra og Funksjoner, og fokuserer på problemløsningsmetoder i eksemplene i de norske og de russiske lærebøkene for ...

    • 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 ...
