Existence of solitary-wave solutions to a class of pseudodifferential evolution equations
(Master thesis, 2016)In this thesis, we present an original existence proof of solitary wave solutions to a class of pseudodifferential evolution equations. We seek traveling waves with constant velocity $c$ of the form $u(x-ct)$ of \begin{ ... -
Existence of uncertainty minimizers for the continuous wavelet transform
(Peer reviewed; Journal article, 2023)Continuous wavelet design is the endeavor to construct mother wavelets with desirable properties for the continuous wavelet transform (CWT). One class of methods for choosing a mother wavelet involves minimizing a functional, ... -
Existence, smoothness and numerical approximation for two generalizations of the stochastic heat equation
(Master thesis, 2023)I denne avhandlingen ser jeg på to klasser av stokastiske evolusjonsligninger. Jeg ser på eksistens og unikhetsresultater for svake løsninger og jeg ser på resultater som beskriver glattheten og kovariansegenskapene til ... -
Exotic Coactions
(Journal article; Peer reviewed, 2016)If a locally compact group G acts on a C *-algebra B, we have both full and reduced crossed products and each has a coaction of G. We investigate ‘exotic’ coactions in between the two, which are determined by certain ideals ... -
Explainability and validity of statistical methods for genome-wide association studies: Extending Shapley-based explanation methods and adapting saddlepoint approximations
(Doctoral theses at NTNU;2022:26, Doctoral thesis, 2022) -
Explaining random forest predictions with partial dependence and accumulated local effects plots
(Bachelor thesis, 2021)Denne bacheloroppgaven tar for seg potensielle bruskområder for to XAI metoder for å analysere svart boks modeller. For å gjøre dette brukes en svart boks model fra statistisk læring, for denne oppgaven er det valgt å bruke ... -
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 ... -
Exploring Dietary Intake in Adults with Severe Obesity and Associations with the FTO rs9939609 Genotypes
(Peer reviewed; Journal article, 2023)Background Few have studied the associations between rs9939609 genotypes in the obesity candidate locus FTO and energy and nutrient intakes and meal frequencies in adults with severe obesity. We are unaware of studies ... -
Exploring Instruction Cache Analysis - On Arm
(Master thesis, 2014)This thesis explores the challenges of implementing an instruction cache side-channel attack on an ARM platform. The information leakage through the instruction cache is formally discussed using information theoretic ... -
Exploring shared genetics between maximal oxygen uptake and disease: the HUNT study
(Journal article; Peer reviewed, 2023)Low cardiorespiratory fitness, measured as maximal oxygen uptake (V̇o2max), is associated with all-cause mortality and disease-specific morbidity and mortality and is estimated to have a large genetic component (∼60%). ... -
Exponential decay of solitary waves to Degasperis-Procesi equation
(Peer reviewed; Journal article, 2020)We improve the decay argument by Bona and Li (1997) [5] for solitary waves of general dispersive equations and illustrate it in the proof for the exponential decay of solitary waves to steady Degasperis-Procesi equation ... -
Exponential Weighted Sums related to the Divisor and Circle Problems
(Master thesis, 2018)The classical results of the Dirichlet Divisor Problem and Gauss' Circle Problem are examined, with required information on the Riemann Zeta function presented. In particular, the results derived from the weighted sums of ... -
Exposing boundary points of strongly pseudoconvex subvarieties in complex spaces
(Journal article; Peer reviewed, 2018)We prove that all locally exposable points in a Stein compact in a complex space can be exposed along a given curve to a given real hypersurface. Moreover, the exposing map for a boundary point can be sufficiently close ... -
Extending quantitative genetic models to estimate mutational variance
(Master thesis, 2021)Dette prosjektet introduserer utvidelser av dyremodellen, en type generalisert lineær blandet modell innen kvantitativ genetikk. Modellen utnytter informasjonen i en kjent slektskapsstruktur for dyre- eller plantepopulasjoner ... -
An extension of Bohr's theorem

Extreme loads analysis of a site-specific semi-submersible type wind turbine
(Peer reviewed; Journal article, 2020)As a vital key part of the modern offshore wind energy industry, floating offshore wind turbines (FOWT) are built to generate green renewable energy. Robust prediction of extreme loads during FOWT operation is an important ... -
Extreme riser experimental loads caused by sea currents in the Gulf of Eilat
(Peer reviewed; Journal article, 2022)Risers are widely used in offshore industry and are subjected to dynamic environmental loads. Robust prediction of extreme riser external loading under the action of sea currents and subsequently VIV (vortex-induced ... -
Extreme Value Analysis & Application of the ACER Method on Electricity Prices
(Master thesis, 2012)In this thesis we have explored the very high prices that sometimes occurs in the Nord Pool electricity market Elspot. By applying AR-GARCH time series models, extreme value theory, and ACER estimation techniques, we have ... -
Extreme value prediction with modified Enhanced Monte Carlo method based on tail index correction
(Peer reviewed; Journal article, 2023)As one of the main branches of extreme statistics, extreme value theory is widely used in marine engineering. Due to its special application in real ocean environmental states, the scale of the obtained monitoring data is ...
