A Comparison Study of Different Optimizing Criteria and Confounding Patterns For Multi-Level Binary Replacement and Other Designs Used in Computer Experiments
(Master thesis, 2011)We have constructed four different types of designs for computer experiments. Thedesign types are based on latin hypercube sampling (LHS), orthogonal arrays (OA), ran-dom sampling and the recently proposed multi-level ... -
A Parallel Multiscale Mixed Finite-Element Method for the Matlab Reservoir Simulation Toolbox
(Master thesis, 2012)We start by giving a brief introduction to reservoirs and reservoir modelling at different scales. We introduce a mathematical model for the two-phase flow, before we look at numerical discretizations. In particular we ... -
Adeles in Mathematical Physics
(Master thesis, 2012)Vi vil utforske bruken av adeler i matematisk fysikk. -
An analysis of Norwegian and American interest rates during turbulent times, and prediction of interest rates in a Heat, Jarrow and Morton Model
(Master thesis, 2012)Abstract:In this master thesis the main focus is an analysis of historical interest rates, and the use of historical interest rates in interest rate modeling. The interest rate data used, both in the preliminary analysis ... -
An Application of the ACER Method to Norwegian Water Level Data: A Comparison of Return Level Estimates
(Master thesis, 2011)In this Master's thesis we have used data from eight different locations in Norway to estimate the distributions of extreme water levels. The locations used are Oslo, Heimsjø, Honningsvåg, Narvik, Harstad, Tregde, Andenes ... -
Analysis of portfolio risk and the LIBOR Market Model
(Master thesis, 2011)This master thesis focuses on interest rate modeling and portfolio risk analysis. The LIBOR Market Model is the interest rate model chosen to simulate the forward rates in the Norwegian and American market, two very different ... -
Anonymity in Network Connections for Mobile Communication
(Master thesis, 2012)This thesis summarizes an existing protocol, that we have chosen to call the Token Key Agreement protocol. It then goes on to introduce two new protocols we have chosen to name the Symmetric Key Agreement protocol and the ... -
Applications of p-adic Numbers to well understood Quantum Mechanics: With a focus on Weyl Systems and the Harmonic Oscillator
(Master thesis, 2012)In this thesis we look at how it is possible to construct models in quantum mechanics by using p-adic numbers. First we look closely at different quantum mechanical models using the real numbers, as it is necessary to ... -
Applying hybrid methods to reduce nonphysical cycles in the flux field
(Master thesis, 2012)In this thesis we present the theoretical background for the two-point flux-approximation method; (TPFA), mimetic discretisation methods, and the multipoint flux approximation method; (MPFA). Theoretical arguments concerning ... -
Computing Almost Split Sequences: An algorithm for computing almost split sequences of finitely generated modules over a finite dimensional algebra
(Master thesis, 2012)An artin algebra $l$ over a commutative, local, artinian ring $R$ was fixed, and with this foundation some topics from representation theory were discussed. A series of functors of module categories were defined, and almost ... -
Discrete Invariant Variational Problems
(Master thesis, 2011)This thesis studies variational problems invariant under a Lie group transformation, and invariant discretizations of these. In chapters two and three, a general method for creating symplectic integrators preserving certain ... -
Divergence-free Isogeometric Methods for Flow in Porous Media
(Master thesis, 2012)This thesis is focused on solving the Darcy flow problem using divergence-free isogeometric methods, and comparing these results to the ones obtained using traditional finite element methods with Taylor Hood elements. A ... -
Efficient Calculation of Optimal Decisions in Graphical Models
(Master thesis, 2012)We present a method for finding the optimal decision on Random Variables in a graphical model. Upper and lower bounds on the exact value for each decision are used to reduce the complexity of the algorithm, while we still ... -
Ensemble Kalman Filter on the Brugge Field
(Master thesis, 2012)The purpose of modeling a petroleum reservoir consists of finding the underlying reservoir properties based on production data, seismic and other available data. In recent years, progress in technology has made it possible ... -
Explicit, A Priori Constrained Model Parameterization for Inverse Problems, Applied on Geophysical CSEM Data
(Master thesis, 2014)This thesis introduce a new parameterization of the model space in global inversion problems. The parameterization provides an explicit representation of the model space with a basis constrained on a priori information ... -
Gryphon - a Module for Time Integration of Partial Differential Equations in FEniCS
(Master thesis, 2012)This thesis aims to implement time integrators in the FEniCS framework. More specifically, the thesis focuses on selecting suitable time integrators, implement these and verify that the implementation works by applying ... -
Krylov Subspace Accelerated Algebraic Multigrid for Mimetic Finite Differences on GPUs
(Master thesis, 2012)The topic of this thesis is GPU accelerated sparse linear algebra for subsurface reservoir modeling. Numerical techniques for reservoir sim- ulations are described and we present the open source reservoir simula- tion ... -
Massey products and Linking
(Master thesis, 2012)This master's thesis is focussed around investigating Massey products as tools for studying properties of links, in particular the Brunnian property. In the literature, there are only a few examples of the Massey product ... -
Modelling risk in multi asset-class portfolios
(Master thesis, 2010)Using a simulation based model, with the Black-Scholes framework for equity andThe LIBOR Market Model for interest rates, we study market risk in multi assetclassportfolios, with static and dynamic weighting. The risk ... -
Multiscale Finite Volume Methods: Extension to Unstructured Grids with Applications in Reservoir Simulation
(Master thesis, 2012)In reservoir simulations, one of the biggest challenges is solving large modelswith complex geological properties. Because reservoirs can be several kilome-ters long, and still be geologically inhomogeneous over centimeters, ...
