Modeling and Inversion of CSEM Data using Green's Function Methods
(Master thesis, 2014-06-01)The aim of the present study is to develop new approximations to the integral equation for 3D Controlled Source Electromagnetic (CSEM) synthetic data. Several scattering approximations to the integral equation have previously ... -
Modeling and inversion of seismic data using multiple scattering, renormalization and homotopy methods
(Doctoral thesis, 2020-05-14)Seismic scattering theory plays an important role in seismic forward modeling and is the theoretical foundation for various seismic imaging methods. Full waveform inversion is a powerful technique for obtaining a high-resolution ... -
Modeling and simulating the sample complexity of solving LWE using BKW-style algorithms
(Journal article; Peer reviewed, 2022)The Learning with Errors (LWE) problem receives much attention in cryptography, mainly due to its fundamental significance in post-quantum cryptography. Among its solving algorithms, the Blum-Kalai-Wasserman (BKW) algorithm, ... -
Modeling and simulation of blood circulation and perfusion
(Doctoral thesis, 2023-06-16)Numeriske simuleringer har hatt vesentlig betydning for vår forståelse av perfusjon og blodsirkulasjon, og simuleringer gir også viktig innsikt under utviklingen av medisinske anvendelser. Teknologiske fremskritt har ... -
Modeling and simulation of concrete carbonation in 1-d using two-point flux approximation
(Master thesis, 2013-11-21)In this master's thesis we will model concrete carbonation using mass conservation equations and Darcy's law. We then get a set of coupled partial differential equations. We also have a ordinary differential equation ... -
Modeling and simulation of EOR due to biofilm formation and gas production
(Master thesis, 2019-06-15)Microbial enhanced oil recovery (MEOR) is a collective term for more environmen- tally friendly enhanced oil recovery (EOR) techniques. EOR methods are techniques used after primary and secondary stage of oil recovery ... -
Modeling and Simulation of Microbial Enhanced Oil Recovery: A New Approach which Includes the Role of Interfacial Area
(Master thesis, 2016-05-31)In today's world, oil remains the main source of energy. After discovering a petroleum reservoir, one can extract about 30% of the oil by using and maintaining the initial pressure in the reservoir through water ooding ... -
Modeling and Upscaling of Deformation Bands in Fault Damage Zones
(Master thesis, 2008) -
Modeling coastal circulation in Norway using a high-resolution 4D-Var ocean assimilation system
(Doctoral thesis, 2017-06-23)The circulation along the Norwegian coast is characterized by many transient smallscale features such as eddies and meanders that are challenging to reproduce by means of numerical modeling. In this thesis I investigate ... -
Modeling compaction effects on the elastic properties of clay-water composites
(Peer reviewed; Journal article, 2012-09)Modeling the elastic properties of clay-bearing rocks (shales) requires thorough knowledge of the mineral constituents, their elastic properties, pore space microstructure, and orientations of clay platelets. Information ... -
Modeling Coupled Nonlinear Multilayered Dynamics: Cyber Attack and Disruption of an Electric Grid
(Journal article; Peer reviewed, 2021)We study the consequences of cyberattack, defense, and recovery in systems for which a physical system is enabled by a cyber system by extending previous applications of models from the population biology of disease to the ... -
Modeling cultural dissemination and divergence between rural and urban regions
(Journal article; Peer reviewed, 2020-10-31)The process by which beliefs, opinions, and other individual, socially malleable attributes spread across a society, known as "cultural dissemination," is a broadly recognized concept among sociologists and political ... -
Modeling Directional Interactions in Classical Molecular Dynamics for Geometrical Aspects of Nanostructures
(Doctoral thesis, 2009-08-21) -
Modeling Dissolution within Vertically Averaged Formulations
(Master thesis, 2010-06-10)In this thesis we develop a mathematical model describing the migration and trapping of CO2 when injecting it in a deep saline aquifer. Both the migration and trapping processes are inherently complex, spanning multiple ... -
Modeling early life history of cod
(Doctoral thesis, 2007-03-02)Newly hatched Atlantic cod (Gadus morhua) larvae face an uncertain future when they first enter their marine pelagic habitat. Prior to complete yolk absorption, the larvae will have to find food. This process includes the ... -
Modeling fitness changes in wild Atlantic salmon populations faced by spawning intrusion of domesticated escapees
(Peer reviewed; Journal article, 2018-07)Genetic interaction between domesticated escapees and wild conspecifics represents a persistent challenge to an environmentally sustainable Atlantic salmon aquaculture industry. We used a recently developed eco‐genetic ... -
Modeling Heat Transport in Systems of Hydrate-Filled Sediments Using Residual Thermodynamics and Classical Nucleation Theory
(Journal article; Peer reviewed, 2021)As in any other phase transition, hydrate phase transition kinetics involves an implicit coupling of phase transition thermodynamic control and the associated dynamics of mass and heat transport. This work provides a brief ... -
