Statistics of Wave Induced Nonlinear Loads and Responses
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:180, Doctoral thesis, 2006)The challenge to calculate the response statistics of nonlinear, compliant offshore structures subjected to a random seaway is still substantial. The topic has been studied intensively for decades, and a substantial amount ... -
Rekursiv blokkoppdatering av Isingmodellen
(Master thesis, 2006)I denne rapporten sammenligner vi tre varianter av Markov Chain Monte Carlo (MCMC) - simulering av Isingmodellen. Vi sammenligner enkeltnode-oppdatering, naiv blokkoppdatering og rekursiv blokkoppdatering. Vi begynner med ... -
Multilevel Analysis Applied to Fetal Growth Data with Missing Values.
(Master thesis, 2006)Intrauterine growth retardation means that the growth of a fetus is restricted as compared with its biological growth potential. This contributes to an increased risk for illnesses or death of the newborn. Therefore it ... -
Om Banachs fikspunktteorem og The Scottish Café: -Anvendelser av Banachs fikspunktteorem. -Kulturhistorisk bakgrunn for forståelsen av The Scottish Café.
(Master thesis, 2006)Sammendrag I kapittel 1 gjøres klart hvilke forkunnskaper som er nødvendige for å kunne forstå og ha utbytte av å lese denne oppgaven. Det henvises også til litteratur som kan brukes som oppslagsverk hvis noen begreper ... -
Hilberttransformpar og negativ brytning
(Master thesis, 2006)I løpet av de siste årene har det blitt mulig å lage medier som har permittivitet $epsilon_r=chi_e+1$ og permeabilitet $mu_r=chi_m+1$ med simultant negative realdeler. I slike medier vil man få negativ brytning og dette ... -
Haarmål og høyreregulær representasjon på kompakte kvantegrupper
(Master thesis, 2006)I denne oppgaven vil vi definere og vise eksistens av haarmål på kompakte kvantegrupper, se på hvordan vi ved hjelp av haarmålet kan konstruere en høyreregulær representasjon. Vi vil så gjøre dette ganske eksplisitt for ... -
On a shallow water wave equation
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:103, Doctoral thesis, 2006)The main topic of this thesis is the study of a nonlinear partial differential equation, the Camassa-Holm (CH) equation: ut - utxx + 3uux - 2uxuxx -uuxxx = 0. -
Sequential Markov random fields and Markov mesh random fields for modelling of geological structures
(Master thesis, 2006)We have been given a two-dimensional image of a geological structure. This structure is used to construct a three-dimensional statistical model, to be used as prior knowledge in the analysis of seismic data. We consider ... -
Interest rate modeling with applications to counterparty risk
(Master thesis, 2006)This thesis studies the estimation of credit exposure arising from a portfolio of interest rate derivatives. The estimation is performed using a Monte Carlo simulation. The results are compared to the exposure obtained ... -
Edge-Detection in Signals using the Continuous Wavelet-Transform.: Edge-Detection in Medical UltraSound Images.
(Master thesis, 2006)Today, UltraSound (US) images are often used in medical examination and surgery. An improvement of the quality of these US-images will lead to many advantages, which is a big motivation for research on this field. One ... -

(Master thesis, 2006)Intrauterine growth retardation means that the growth of a fetus is restricted as compared with its biological growth potential. This contributes to an increased risk for illnesses or death of the newborn. Therefore it ... -
Lie group and exponential integrators: Theory, implementation, and applications
(Doctoral thesis, 2006)This PhD-thesis contains an introduction and six research papers sorted chronologically, of which the first four are accepted for publication. The introduction aims at giving a very brief summary of the background theory ... -
Bayesian 4D inversion: integrating time-shift information
(Master thesis, 2006)A new inversion method for time-lapse seismic data is developed. The method is based on the 3-dimensional spatially coupled AVO inversion in the Fourier domain, describedin Buland et al. (2003b). Further, a technique for ... -
Financial Risk, Risk Appetite and the Macroeconomic Environment
(Master thesis, 2006)This thesis seeks to establish a methodology to reveal whether the risk appetite held by investors is dependent on the macroeconomic environment and, if present, to quantify this dependency. To do so a generic model is ... -
In silico Investigation of Possible Mitotic Checkpoint Signalling Mechanisms
(Master thesis, 2007)The mitotic checkpoint is the major bio-chemical pathway acting to ensure stable genome content in cell division. A delay in chromosome segregation is enforced as long as at least one kinetochore is in lack of proper ... -
Modeling collateralized debt obligations: A copula approach
(Master thesis, 2007)This master thesis gives an introduction to collateralized debt obligations (CDOs), and presents three models for pricing CDO tranches - The Vasicek model, which is considered to be the standard market model, the double ... -
Local Analysis of Ocean Wave Measurements
(Master thesis, 2007)This master thesis investigates the Short Time Fourier transform and the Continuous Wavelet transform in relation to a directional analysis of in situ ocean wave measurements. We have determined the statistical properties ... -
Numerical Simulation of Interacting Bodies with Delays; Application to Marine Seismic Source Arrays.
(Master thesis, 2007)This master thesis has looked at numerical simulation of interacting bodies with delays, especially the situation involving interacting airguns in seismic source arrays. The equations describing the airguns have been ... -
Bandwith selection based on a special choice of the kernel

Recurrent Neural Network for Learning and Reproducing Movements
(Master thesis, 2007)In this thesis I study how movements can be learned and stored by a recurrent neural network. Also I investigate how a movement can be associated with an external context, and wether this can be used to produce movements ...
