This application-oriented work concerns the design of efficient, robust and reliable
algorithms for the numerical simulation of multiscale phenomena. To this end, various …

This paper presents an effective paradigm to make full use of both Deep Reinforcement
Learning (DRL) and expert knowledge to find an optimal control strategy. The paradigm …

This paper proposes a new grid-free adaptive advection scheme. The resulting algorithm is
a combination of the semi-Lagrangian method (SLM) and the grid-free radial basis function …

Presented in this work is an explicit finite volume method for solving general hyperbolic
systems on the surface of a sphere. Applications where such systems arise include passive …

Abstract Adaptive Mesh Refinement (AMR) provides an attractive framework for atmospheric
flows since it allows improved horizontal resolution in a limited region without requiring a …

A new computational method for solving the shallow-water equations has been developed.
This method combines some of the recent developments of geophysical and computational …

A new parallel partitioning algorithm for unstructured par-allel grid generation is presented.
This new approach is based on a space-filling curve. The space-filling curve's indices are …

In previous work, a new adaptive meshfree advection scheme for numerically solving linear
transport equations has been proposed. The scheme, being a combination of an adaptive …
