(Research report / Forskningsrapport, 1992)
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
The coupled Darcy–Stokes problem is widely used for modeling fluid transport in physical systems consisting of a porous part and a free part. In this work we consider preconditioners for monolithic solution algorithms of ...

The bidomain system of degenerate reaction–diffusion equations is a well-established spatial model of electrical activity in cardiac tissue, with “reaction” linked to the cellular action potential and “diffusion” representing ...
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
We derive and study a Lax–Friedrichs-type finite volume method for a large class of nonlocal continuity equations in multiple dimensions. We prove that the method converges weakly to the measure-valued solution and converges ...

On reduced twisted group C*-algebras that are simple and/or have a unique trace
(Research report / Forskningsrapport, 2011)
Predicting the reliability of software systems based on a component-based approach is inherently difficult, in particular due to failure dependencies between software components. One possible way to assess and include ...

In 1994, Nessyahu, Tadmor and Tassa studied convergence rates of monotone finite volume approximations of conservation laws. For compactly supported, Lip+-bounded initial data they showed a first-order convergence rate in ...
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
A conceptual variable is any variable defined by a person or by a group of persons. Such variables may be inaccessible, meaning that they cannot be measured with arbitrary accuracy on the physical system under consideration ...
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
Time integration of Fourier pseudospectral DNS is usually performed using the classical fourth‐order accurate Runge‐Kutta method or other second‐ or third‐order methods, with a fixed step size. We investigate the use of ...
(Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2019)
Environmental contours are widely used as a basis for e.g., ship design, especially in early design phases. The traditional approach to such contours is based on the well-known Rosenblatt transformation. In the present ...
