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 ... -
Integral conditions for Skorohod stochastic differential equations
(Statistical report no. 24, Research report, 1994-06) -
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 ... -
Interfaces in a knowledge-based statistical system, as exemplified by Express

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 ... -
Invariant connections, Lie algebra actions, and foundations of numerical integration on manifolds
(Journal article; Peer reviewed, 2020)Motivated by numerical integration on manifolds, we relate the algebraic properties of invariant connections to their geometric properties. Using this perspective, we generalize some classical results of Cartan and Nomizu ... -
Inversion of CSEM Data for Subsurface Structure Identification and Numerical Assessment of the Upstream Mobility Scheme
(Doctoral thesis, 2015-03-27)Part I In this part of the thesis, two different methodologies for solving the inverse problem of mapping the subsurface electric conductivity distribution using controlled source electromagnetic (CSEM) data are presented. ... -
Investigating population genetic structure in a highly mobile marine organism: The minke whale Balaenoptera acutorostrata acutorostrata in the North East Atlantic
(Peer reviewed; Journal article, 2014-09-30)Inferring the number of genetically distinct populations and their levels of connectivity is of key importance for the sustainable management and conservation of wildlife. This represents an extra challenge in the marine ... -
Investigating the Asymmetric Behavior of Oil Price Volatility Using Support Vector Regression
(Journal article; Peer reviewed, 2022)This paper investigates the asymmetric behavior of oil price volatility using different types of Asymmetric Power ARCH (APARCH) model. We compare the estimation and forecasting performance of the models estimated from the ... -

Investigations of the Kaup-Boussinesq model equations for water waves
(Master thesis, 2014-06-02)The Kaup-Boussinesq system is a coupled system of nonlinear partial differential equations which has been derived as a model for surface waves in the context of the Boussinesq scaling, and it has also been derived for an ... -
Investigations of the Modified Navier-Stokes Equations in One Dimension
(Master thesis, 2014-06-02)In this thesis we have investigated the Brenner-Navier-Stoke equations in one spatial dimension. These are a modified version of the Navier-Stokes equations, where the modification relates to a mass diffusion term. This ... -
Irreducible unirational and uniruled components of moduli spaces of polarized Enriques surfaces
(Journal article; Peer reviewed, 2023)We prove that infinitely many irreducible components of the moduli space of polarized Enriques surfaces are unirational (resp. uniruled), characterizing them in terms of decompo- sitions of the polarization as an effective ... -
