The Whitham Equation as a model for surface water waves
(Elsevier, 2015-08)
The Whitham equation was proposed as an alternate model equation for the simplified description of uni-directional wave motion at the surface of an inviscid fluid. As the Whitham equation incorporates the full linear ...
Numerical bifurcation for the capillary Whitham equation
(Elsevier, 2017-03)
The so-called Whitham equation arises in the modeling of free surface water waves, and combines a generic nonlinear quadratic term with the exact linear dispersion relation for gravity waves on the free surface of a fluid ...
Investigating population genetic structure in a highly mobile marine organism: The minke whale Balaenoptera acutorostrata acutorostrata in the North East Atlantic
(PLoS, 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 ...
Non-standard shocks in the Buckley-Leverett equation
(Elsevier, 2015-08)
It is shown how delta shock waves which consist of Dirac delta distributions and classical shocks can be used to construct non-monotone solutions of the Buckley–Leverett equation. These solutions are interpreted using a ...
Do abnormal serum lipid levels increase the risk of chronic low back pain? The Nord-Trøndelag Health Study
(Public Library of Science, 2014-09-18)
Background: Cross-sectional studies suggest associations between abnormal lipid levels and prevalence of low back pain (LBP), but it is not known if there is any causal relationship. Objective: The objective was to determine, ...
Layout of CCS monitoring infrastructure with highest probability of detecting a footprint of a CO2 leak in a varying marine environment
(Elsevier, 2015-04-04)
Monitoring of the marine environment for indications of a leak, or precursors of a leak, will be an intrinsic part of any subsea CO2 storage projects. A real challenge will be quantification of the probability of a given ...
Two-phase flow in porous media: dynamic capillarity and heterogeneous media
(Springer, 2015-08-11)
We investigate a two-phase porous media flow model, in which dynamic effects are taken into account in phase pressure difference. We consider a one-dimensional heterogeneous case, with two adjacent homogeneous blocks ...
Trigonometric interpolation on lattice grids
(Springer, 2015)
In this paper we construct non-aliasing interpolation spaces and Lagrange functions for lattice grids. We argue that lattice grids are good for trigonometric interpolation and support this claim by numerical experiments. ...
Vertically averaged equations with variable density for CO2 flow in porous media
(Springer, 2015-03)
Carbon capture and storage has been proposed as a viable option to reduce CO 2 emissions. Geological storage of CO 2 where the gas is injected into geological formations for practically indefinite storage, is an integral ...
Determining individual variation in growth and its implication for life-history and population processes using the Empirical Bayes method
(PLoS, 2014-09-11)
The differences in demographic and life-history processes between organisms living in the same population have important consequences for ecological and evolutionary dynamics. Modern statistical and computational methods ...
