Identification of a nonlinear parameter in a parabolic equation by a linear approach
(Department of Applied Mathematics report, Research report, 1993-03) -
Identification of subsurface structures using electromagnetic data and shape priors
(Journal article, 2015-03)We consider the inverse problem of identifying large-scale subsurface structures using the controlled source electromagnetic method. To identify structures in the subsurface where the contrast in electric conductivity can ... -
Ill Posedness Results for Generalized Water Wave Models
(Master thesis, 2013-06-03)In the first part of the study, the weak asymptotic method is used to find singular solutions of the shallow water system in both one and two space dimensions. The singular solutions so constructed are allowed to contain ... -

(Master thesis, 2009-07-17) -
Image Inpainting using Nonlinear Partial Differential Equations
(Master thesis, 2005-05-23) -
Image processing, filtering and segmentation of data-sets for reservoir simulation
(Doctoral thesis; Peer reviewed, 2013-10-11)Paper A: 2-D Visualisation of Unstable Waterflood and Polymer Flood for Displacement of Heavy Oil. Full-text not available in BORA. The published version is available at: http://dx.doi.org/10.2118/154292-ms -
Impact and detectability of hypothetical CCS offshore seep scenarios as an aid to storage assurance and risk assessment
(Journal article; Peer reviewed, 2020)Carbon Capture and Storage has the potential to make a significant contribution to the mitigation of climate change, however there is a regulatory and societal obligation to demonstrate storage robustness and minimal local ... -
Impact of compressibility in vertically integrated models for CO2 storage
(Master thesis, 2012-06-01)Recent work have shown that simplified models obtained by vertical integration give reasonable approximations for CO2 migration. Most of the work previously done on this topic assumes that CO2 is an incompressible fluid, ... -
Impact of drone route geometry on information collection in wireless sensor networks
(Journal article; Peer reviewed, 2020-09)The recent technological evolution of drones along with the constantly growing maturity of its commercialization, has led to the emergence of novel drone-based applications within the field of wireless sensor networks for ... -
The impact of local-scale processes on large-scale CO2 migration and immobilization
(Peer reviewed; Journal article, 2011)Storage security of injected carbon dioxide (CO2) is an essential component of risk management for geological carbon sequestration operations. During the injection and early post-injection periods, CO2 leakage may occur ... -
Impact of temporomandibular joint complaints on tinnitus-related distress
(Peer reviewed; Journal article, 2019-08-22)There is increasing evidence of associations between the presence of temporomandibular joint (TMJ) disorders and tinnitus. It has been recently proposed that tinnitus patients with TMJ complaints could constitute a subtype, ... -
Implementation of an MPFA/MPSA-FV Solver for the Unsaturated Flow in Deformable Porous Media
(Master thesis, 2018-06-22)The Unsaturated Flow In Deformable Porous Media (UFIDPM) plays a crucial role in several academic and industrial applications such as; cracks induced by desiccation, collapsing soils, ground movement involving expansive ... -
Implementation of mixed-dimensional models for flow in fractured porous media
(Peer reviewed; Journal article, 2019)Models that involve coupled dynamics in a mixed-dimensional geometry are of increasing interest in several applications. Here, we describe the development of a simulation model for flow in fractured porous media, where the ... -
Implications of Protected Areas to Optimal Management of Marine Resources
(Master thesis, 2005)The thesis explores how the introduction of a marine protected area influences the optimal management of a marine resource, i.e. fish stock. Logistic growth functions are applied to a deterministic model with a migration ... -
Improving the error rates of the Begg and Mazumdar test for publication bias in fixed effects meta-analysis
(Peer reviewed; Journal article, 2014-09-22)Background: The rank correlation test introduced by Begg and Mazumdar is extensively used in meta-analysis to test for publication bias in clinical and epidemiological studies. It is based on correlating the standardized ... -
Inexact linear solvers for control volume discretizations in porous media
(Peer reviewed; Journal article, 2014-12-03)We discuss the construction ofmulti-level inexact linear solvers for control volume discretizations for porous media. The methodology forms a contrast to standard iterative solvers by utilizing an algebraic hierarchy of ... -
Influence of natural convection in a porous medium when producing from borehole heat exchangers
(Peer reviewed; Journal article, 2013-08)Convection currents in a porous medium form when the medium is subject to sufficient heating from below (or equivalently, cooling from above) or when cooled or heated from the side. In the context of geothermal energy ... -
Injective braids, braided operads and double loop spaces
(Master thesis, 2011-06-01)We construct the category of B-spaces, which is a braided monoidal diagram category. This category is Quillen equivalent to the category of simplicial sets. The induced equivalence of homotopy categories maps a commutative ... -

Interest rate models in Solvency II
(Master thesis, 2016-11-21)The best estimate of liabilities is important in the Solvency II framework. The best estimate of liabilities should be probability weighted average of future cash flows discounted to its present value. Life insurance ...
