Implicit linearization scheme for nonstandard two-phase flow in porous media
(Journal article; Peer reviewed, 2021)In this article, we consider a nonlocal (in time) two‐phase flow model. The nonlocality is introduced through the wettability alteration induced dynamic capillary pressure function. We present a monotone fixed‐point iterative ... -
Improving Sequential Decisions – Efficiently Accounting for Future Learning
(Journal article; Peer reviewed, 2021)In sequential field development planning, past decisions not only directly affect the maximum achievable expected NPV but also influence the future information that can be used to reduce geological uncertainty. To act ... -
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 ... -
Individual-Based Modelling As a Tool for Sustainable Red Deer Management
(Master thesis, 2019-06-15)Being able to predict how a population of red deer evolve over time for different hunting strategies, can be helpful for wildlife management in their decision-making as means for achieving a sustainable red deer population. ... -
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 ... -

The influence of directional spreading on rogue waves triggered by abrupt depth transitions
(Journal article; Peer reviewed, 2023)An increased number of rogue waves, relative to standard distributions, can be induced by unidirectional waves passing over abrupt decreases in water depth. We investigate this phenomenon in a more general setting 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 ... -
Insights from cardiopulmonary exercise testing in pediatric patients with hypertrophic cardiomyopathy
(Journal article; Peer reviewed, 2021)The usefulness of cardiopulmonary exercise test (CPET) in adult hypertrophic cardiomyopathy (HCM) patients is well-known, whereas its role in pediatric HCM patients has not yet been explored. The present study investigates ... -

Integration by Riemann triangles
(Journal article; Peer reviewed, 2024)In this article we present a method of integration inspired by an example from Proofs Without Words II by Nelsen. Riemann rectangles under a curve are transformed into triangles. The limit of the collection of triangles ... -
Interdisciplinary and Transferable Concepts in Bioinformatics Education: Observations and Approaches From a UK MSc Course
(Journal article; Peer reviewed, 2022-02-24)Bioinformatics is a highly interdisciplinary subject, with substantial and growing influence in health, environmental science and society, and is utilised by scientists from many diverse academic backgrounds. Education in ... -
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 ... -

Internal pressure gradient errors in sigma-coordinate ocean models: The finite volume and weighted approaches
(Master thesis, 2010-04-26)Terrain-following (sigma-coordinate) models are widely used. They are often advantageous when dealing with large variations in topography, and give an accurate representation of the bottom and top boundary layers. However, ... -
International Conference on Greenhouse Gas Technologies (GHGT-12) Models for CO2 injection with coupled thermal proce
(Peer reviewed; Journal article, 2014)Large-scale models of carbon dioxide (CO2) storage in geological formations must capture the relevant physical, chemical and thermodynamic processes that affect the migration and ultimate fate of injected CO2. These processes ... -
Intervall mellom fødslar studert ved "Phase Type Distributions"
(Master thesis, 2011-05-31)Omhandlar tida mellom første og andre barn studert ved "Phase Type Distributions". Ser på desse tidene som overlevelsestider og prøver å tilpasse ein phase type fordeling til datasettet me ser på. Brukar også glatting av ... -
Intracellular Energy Variability Modulates Cellular Decision-Making Capacity
(Journal article; Peer reviewed, 2019)Cells generate phenotypic diversity both during development and in response to stressful and changing environments, aiding survival. Functionally vital cell fate decisions from a range of phenotypic choices are made by ...
