A blockyness Constraint for seismic AVA Inversion
(Master thesis, 2008)The aim of seismic inversion is to determine the distribution of elastic parameters from recorded seismic reflection data. If a combination of elastic parameters is known, they indicate a certain fluid or lithology. Elastic ... -
A comparison of accuracy and computational efficiency between the Finite Element Method and the Isogeometric Analysis for two-dimensional Poisson Problems
(Master thesis, 2009)For small error the isogeometric analysis is more efficient than the finite element method. The condition number is lower in the isogeometric analysis than the finite element method. The isogeometric analysis produce general ... -
A General Face Recognition System
(Master thesis, 2006)In this project a real-time face detection and recognition system has been discussed and implemented. The main focus has been on the detection process which is the first and most important step before starting with the ... -
A heavy tailed statistical model applied in anti-collision calculations for petroleum wells
(Master thesis, 2008)Anti-collision calculations are done during the planning of a new petroleum well. These calculations are required in order to control the risk of having a well-collision, which is an unwanted event at any cost. The risk ... -
A Parallel Implementation of Mortal Random Walkers in the Pore Network of a Sandstone
(Master thesis, 2008)Simulations of the nuclear magnetic resonance relaxation method is an important part of a digital laboratory developed by Numerical Rocks. The laboratory is used to model petrophysical properties and simulating fluid flow ... -
A statistical simulation-based framework for sample size considerations in case-control SNP association studies
(Master thesis, 2008)In the thesis, a statistical simulation-based framework is presented that is intended for making sample size and power considerations prior to case-control association studies. It reviews biological background and biallelic ... -
A Study of higher order Cellular Automata with Examples
(Master thesis, 2008)Cellular automata are discrete dynamical systems which are practical to use for simulations. Higher order cellular automata are a natural extension of cellular automata, and are expected to be a useful way of improving ... -
Accurate discretizations of torqued rigid body dynamics
(Master thesis, 2010)This paper investigates the solution of the free rigid body equations of motion, as well as of the equations governing the torqued rigid body. We will consider two semi-exact methods for the solution of the free rigid body ... -
Advanced Filtering in Intuitive Robot Programming
(Master thesis, 2006)This text deals with the problem of reducing multi-dimensional data in the context of programming an industrial robot. Different ways to treat the positional and orientational data are discussed, and algorithms for each ... -
An adaptive isogeometric finite element analysis
(Master thesis, 2009)In this thesis we will explore the possibilities of making a finite element solver for partial differential equations using the isogeometric framework established by Hughes et al. Whereas general B-splines and NURBS only ... -
An empirical study of the maximum pseudo-likelihood for discrete Markov random fields.
(Master thesis, 2009)In this text we will look at two parameter estimation methods for Markov random fields on a lattice. They are maximum pseudo-likelihood estimation and maximum general pseudo-likelihood estimation, which we abbreviate ... -
Analysis of commom cause failures in complex safety instrumented systems
(Master thesis, 2008)Common cause failures (CCFs) have been an important issue in reliability analysis for several decades, especially when dealing with safety instrumented systems (SIS). Different approaches have been used in order to describe ... -
Analysis of Hedging Portfolios in Turbulent Markets
(Master thesis, 2008)Two different strategies, one dynamic and one static, were investigated on portfolios consisting of one long index and one long European put (at-the-money or 10% out-of-the-money). Three indices were considered: The MSCI ... -
Analysis of Longitudinal Data with Missing Values.: Methods and Applications in Medical Statistics.
(Master thesis, 2009)Missing data is a concept used to describe the values that are, for some reason, not observed in datasets. Most standard analysis methods are not feasible for datasets with missing values. The methods handling missing data ... -
Analysis of the Transport Layer Security protocol
(Master thesis, 2010)In this master thesis we have presented a security analysis of the TLS protocol with particular emphasis on the recently discovered renegotiation attack. From our security proof we get that the Handshake protocol with ... -
Application of the wavelet transform for analysis of ultrasound images
(Master thesis, 2008)In this master thesis we analyse medical ultrasound images using the wavelet transform. Mathematical theory is introduced for both one-dimensional and two-dimensional functions. Three edge detectors based on the mathematical ... -
Applications of splitting Methods and exponential Integrators to an electro-chemical Heart Cell Model
(Master thesis, 2007)In this thesis we discuss how a system of ordinary differential equations (ODE) describing electro-chemical processes in a heart cell can be solved by numerical methods. The system is stiff, and explicit numerical solvers ... -
Approximate recursive calculations of discrete Markov random fields
(Master thesis, 2010)In this thesis we present an approximate recursive algorithm for calculations of discrete Markov random fields defined on graphs. We write the probability distribution of a Markov random field as a function of interaction ... -
Aspects of Applying the ACER Method to Ocean Wave Data
(Master thesis, 2010)This thesis gives a presentation of the classical Peaks Over Threshold (POT) method and the recently developed Average Conditional Exceedence Rates (ACER) method. Real life ocean significant wave height data sets, each ... -
Aspects of first and second order cellular automata
(Master thesis, 2010)An introduction to the field of Higher-Order Cellular Automata (HOCA) is provided. Key concepts are defined and illustrated using examples. Some of the possibilities offered by this framework are explored, and used to take ...
