VECMAtk: A Scalable Verification, Validation and Uncertainty Quantification Toolkit for Scientific Simulations
D. Groen, H. Arabnejad, V. Jancauskas +23
We present the VECMA toolkit (VECMAtk), a flexible software environment for single and multiscale simulations that introduces directly applicable and reusable procedures for verifi…
Stochastic parameterization with VARX processes
Nick Verheul, Daan Crommelin
In this study we investigate a data-driven stochastic methodology to parameterize small-scale features in a prototype multiscale dynamical system, the Lorenz '96 (L96) model. We pr…
Resampling with neural networks for stochastic parameterization in multiscale systems
Daan Crommelin, Wouter Edeling
In simulations of multiscale dynamical systems, not all relevant processes can be resolved explicitly. Taking the effect of the unresolved processes into account is important, whic…
Computing first passage times for Markov-modulated fluid models using numerical PDE problem solvers
Debarati Bhaumik, Marko A. A. Boon, Daan Crommelin +2
A popular method to compute first-passage probabilities in continuous-time Markov chains is by numerically inverting their Laplace transforms. Past decades, the scientific computin…
