  • Adaptive Multiscale Methods Based on A Posteriori Error Estimates 

    Alyaev, Sergey (The University of Bergen, 2010-06-01)
    We give an overview of different methods for solving highly heterogeneous elliptic problems with multiscale structure and no intuitive scale separation. We compare different finite element variational multiscale methods ...

  • Tokamerarekonstruksjon og Gröbnerbasar 

    Slinde, Kristine Njøs (The University of Bergen, 2016-06-01)
    I denne oppgåva skal me sjå på korleis ein skal gå fram for å rekonstruere ei scene frå to bilete. Dette kan brukast når ein skal evaluere satellittbilete og gjere ei kalibrering av kamera. Me skal sjå på geometrien og ...

  • 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 ...

  • 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 ...

  • Higher Hocschild homology is not a stable invariant 

    Tenti, Andrea (The University of Bergen, 2016-05-27)
    The purpose of this thesis is to study the higher Hochschild homology of some rational algebras. We know that for some algebras the higher Hochschild homology is a stable invariant. Studying the homology over the spheres ...

  • Vurdering for læring i matematikk - vurderingspraksis i 1YT i to klassar på elektrofag 

    Årdal, Jill Berit (The University of Bergen, 2016-05-31)
    Denne oppgåva handlar om formativ vurdering i matematikk. I problemstillinga spør ein etter i kva grad kapittel- og lekseprøver i 1YT har ein formativ funksjon for elevar på elektrofag. Ein skil mellom formål og funksjon ...

  • Alternative læringsmåter for derivasjon i R1 - en komparativ analyse 

    Aksdal, Tom (The University of Bergen, 2016-06-01)
    I denne masteroppgaven har jeg studert elever som har arbeidet med derivasjon i matematikk R1. Formålet har vært å sammenligne to alternative læringsmåter med tradisjonell oppgaveregning, med tanke på læringsutbytte på ...

  • Elevers holdninger til matematikk i videregående skole 

    Ludvigsen, Gerd Anne (The University of Bergen, 2016-06-01)
    Målet med oppgaven har vært å få en dypere innsikt og mer kunnskap om elevers holdninger til matematikken på et høyere nivå i videregående skole. Ut fra et sosialkonstruktivistisk perspektiv har fokus vært rettet mot ...

  • Analysis of non-linear shallow water equations discretized on Arakawa C-grids 

    Eidsvåg, Espen Knudsen (The University of Bergen, 2016-06-01)
    To model the behaviour of flow and waves in three dimensions, one may use the Navier-Stokes equations. These equations leads to the shallow water equations, when the depth is much smaller than the wavelength. The shallow ...

  • Is there a U-shaped relationship between physical activity in leisure time and risk of chronic low back pain? A follow-up in the HUNT Study 

    Heuch, Ingrid; Heuch, Ivar; Hagen, Knut; Zwart, John-Anker (BioMed Central, 2016-04-11)
    Background: Physical activity in leisure time is often considered to have favourable effects on the risk of low back pain (LBP), but demonstrating a definite association in epidemiological studies has proven difficult. The ...

  • Mathematical Modeling and Simulation for Microbial Enhanced Oil Recovery Optimization 

    Kassa, Abay Molla (The University of Bergen, 2016-06)
    In this study, we developed a mathematical model for 2D microbial EOR technology. It consists of an average pressure formulation of two-phase flow and component advection-diffusion reactive transport models. An IFT reduction ...

  • 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 ...
