C*-crossed products
(Master thesis, 2008)We define and study the so-called C*-crossed product construction, primarily from the point of view of C*-dynamical systems, but we will also look at how crossed products (by commutative C*-algebras) arise as C*-algebras ... -
Changepoint Models
(Master thesis, 2009)In this thesis we study recursion methods for making Bayesian inference on a class of multiple changepoint models, introduced in Fearnhead(2006). We present and implement recursion algorithms, and we evaluate how parameter ... -
Classification of seismic waveform attributes in a Bayesian framework
(Master thesis, 2009)The work conducted in this thesis is an extension of an existing methodology developed at Schlumberger Stavanger Research. The Extrema Classification method (Borgos, 2003) provides a framework for automated mapping of ... -
Closed-skew Distributions: Simulation, Inversion and Parameter Estimation
(Master thesis, 2010)Bayesian closed-skew Gaussian inversion is defined as a generalization of traditional Bayesian Gaussian inversion. Bayesian inversion is often used in seismic inversion, and the closed-skew model is able to capture the ... -
Combining the MAX test with methods for Family-wise error rate
(Master thesis, 2008)In chapter 1 the necessary biological background for this thesis is provided. Here the definition of a SNP is provided and the connection between the human genom, DNA and SNPs. Chapter 2 gives the notation and definitions ... -
Comparision of methods and software tools for availability assessment of production systems
(Master thesis, 2008)This thesis presents and considers several different methods for computation of availability and production availability for production system. It is assumed that the system handles flow of a fluid. The thesis presents two ... -
Comparison of ACER and POT Methods for estimation of Extreme Values
(Master thesis, 2010)Comparison of the performance of the ACER and POT methods for prediction of extreme values from heavy tailed distributions. To be able to apply the ACER method to heavy tailed data the ACER method was first modified to ... -
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 ... -
Computing Metrics on Riemannian Shape Manifolds: Geometric shape analysis made practical
(Master thesis, 2009)Shape analysis and recognition is a field ripe with creative solutions and innovative algorithms. We give a quick introduction to several different approaches, before basing our work on a representation introduced by Klassen ... -
Constructing elliptic curves over finite fields using complex multiplication
(Master thesis, 2006)We study and improve the CM-method for the creation of elliptic curves with specified group order over finite fields. We include a thorough review of the mathematical theory needed to understand this method. The ability ... -
Continuation and Bifurcation software in MATLAB
(Master thesis, 2008)This article contains discussions of the algorithms used for the construction of the continuation software implemented in this thesis. The aim of the continuation was to be able to perform continuation of equilibria and ... -
Contrasting broadly adopted model-based portfolio risk measures with current market conditions
(Master thesis, 2009)The last two years have seen the most volatile financial markets for decades with steep losses in asset values and a deteriorating world economy. The insolvency of several banks and their negative impact on the economy has ... -
Design Optimization of Propeller Duct
(Master thesis, 2009)This Master Thesis ends up in a design optimization of a propeller duct profile as an example of multi-objective optimization with computationally expensive objective function evaluation. Computational Fluid Dynamics ... -
Development of a new algorithm for measurement of fatigue and stress in steel
(Master thesis, 2009)A study is done on the transient phase of a voltage signal resulting from a current regulated four point probe measurement on steel plates. Some electromagnetic theory is developed, including a study of the effects of ... -
Discontinuous Galerkin Methods with Optimal Ordering for Fast Reservoir Simulation on General Grids
(Master thesis, 2006)This thesis presents a fast solution strategy for a class of hyperbolic transport equations modelling flow in porous media. The basis of the strategy is discontinuous Galerkin schemes which combined with a numerical flux ... -
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 ... -
Dynamic High Frequency Trading Models
(Master thesis, 2009)This thesis considers constructing high-frequency quantitative trading models. The work is a continuation of my project thesis (spring 2009) and Birgitte Ringstad Vartdal's master thesis (2000). We build our trading model ... -
Effect of Safe Failures on the Reliability of Safety Instrumented Systems
(Master thesis, 2008)Safety instrumented systems (SISs) are of prime importance to the process industry to avoid catastrophic consequences or even loss of human life. The dangerous situations that any equipment may face should be analysed in ... -
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 ...
