Control Strategies Impacts during Low-Level Jet Events on a 15MW Floating Wind Turbine
(Master thesis, 2024-06-03)The size and complexity of wind turbines are increasing as the energy demand continues to grow. Offshore wind energy has significant potential, and the floating 15MW wind turbine has become the new standard in the venture. ... -
Controllability on Infinite-Dimensional Manifolds: A Chow-Rashevsky Theorem
(Peer reviewed; Journal article, 2014-04-29)One of the fundamental problems in control theory is that of controllability, the question of whether one can drive the system from one point to another with a given class of controls. A classical result in geometric control ... -
Controls of basement fabric on cover faulting in strike-slip regimes: analogue physical models of faults using plaster
(Master thesis, 2015-06-01)The full complexity of deformation associated with natural faults is difficult to understand, given the lack of three-dimensional exposure in outcrop and the limitations of seismic resolution in the sub-surface. Analogue ... -
Controls of fault zone structure on synthetic seismic images of the Maghlaq Fault, Malta
(Master thesis, 2020-06-25)Application of seismic reflection data and 2D seismic modelling studies based on field analogues, contribute to closing the scale gap between field observations and interpretation of seismic data. This has improved the ... -
Controls on architecture and seismic imaging of igneous intrusions: Examples from LIDAR outcrop data on Traill Ø (East Greenland) and seismic data from the conjugate Møre Margin
(Master thesis, 2017-06-27)Intrusion of sills into sedimentary successions is a fundamental and widespread process in basins at volcanic rifted margins. Although intrusions emplaced at shallow paleodepths (<1.5 km) are relatively well understood, ... -
Controls on deformation band formation in carbonate grainstones along the Maghlaq Fault, Malta.
(Master thesis, 2018-06-20)Deformation bands are common structures in deformed porous rocks and sediments, that localise strain in millimetre to centimetre thick tabular zones. Deformation bands occurring in siliciclastic rocks have been described ... -
Controls on hydrocarbon column-heights in the Eastern province of Haltenbanken, the Norwegian Sea
(Master thesis, 2016-11-08)Knowledge of controls on hydrocarbon column-heights is highly relevant in hydrocarbon exploration, and important for determination of in-place volumes of prospects. The eastern province of Haltenbanken in the Norwegian Sea ... -
Controls on hydrocarbon column-heights in the north-eastern North Sea
(Master thesis, 2015-06-30)Knowledge about the controls on hydrocarbon column-heights is important in hydrocarbon exploration, as such column heights are the main controlling factor for in-place volumes of prospects. The north-eastern Viking Graben ... -
Controls on river patterns in active tectonic settings in the central Italian Apennines
(Master thesis, 2016-05-31)The central Italian Apennines have gone through a complex evolutionary history, involving compression and subsidence, followed by extension and uplift. The last 3 Ma, the area has experienced active extension, and presently ... -
Convection in the Magnetosphere-Ionosphere System: A Multimission Survey of Its Response to IMF By Reversals
(Journal article; Peer reviewed, 2020)Past studies have demonstrated that the interplanetary magnetic field (IMF) By component introduces asymmetries in the magnetosphere‐ionosphere (M‐I) system, though the exact timings involved are still unclear with two ... -
Convective chimneys and plumes in the Northern Greenland Sea
(Geophysical Monograph Series;30, Chapter, 2005)In the Boreas Basin in the northern Greenland Sea, convection has been observed to be localized as narrow structures - chimneys - in which the water masses may be homogeneous from the surface through great depths. An ... -
Convective mixing in geological carbon storage
(Doctoral thesis, 2011-11-25)The industrial era has seen an exponential growth in the atmospheric concentration of carbon dioxide (CO2), resulting mainly from the burning of fossil fuels. This can cause changes in the climate that have severe impacts ... -
Convergence of a Cell-Centered Finite Volume Discretization for Linear Elasticity
(Peer reviewed; Journal article, 2015-11-19)We show convergence of a cell-centered finite volume discretization for linear elasticity. The discretization, termed the MPSA method, was recently proposed in the context of geological applications, where cell-centered ... -
Convergence of Chandrashekar’s Second-Derivative Finite-Volume Approximation
(Journal article; Peer reviewed, 2023)We consider a slightly modified local finite-volume approximation of the Laplacian operator originally proposed by Chandrashekar (Int J Adv Eng Sci Appl Math 8(3):174–193, 2016, https://doi.org/10.1007/s12572-015-0160-z). ... -
Convergence of energy stable finite-difference schemes with interfaces
(Journal article; Peer reviewed, 2021)We extend the convergence results in Svärd and Nordström (2019) [7] for single-domain energy-stable high-order finite difference schemes, to include domains split into several grid blocks. The analysis also demonstrates ... -
Convergence of Feedback Arc Set-Based Heuristics for Linear Structural Equation Models
(Journal article; Peer reviewed, 2022)Score-based structure learning in Bayesian networks, where local structures in the graph are given a score and one seeks to recover a high-scoring DAG from data, is an NP-hard problem. While the general learning problem ... -

A convergent mass conservative numerical scheme based on mixed finite elements for two-phase flow in porous media
(Research report, 2017)In this work we present a mass conservative numerical scheme for two-phase flow in porous media. The model for flow consists on two fully coupled, non-linear equations: a degenerate parabolic equation and an elliptic ...
