Multiscale Modeling Framework using Element-based Galerkin Methods for Moist Atmospheric Limited-Area Simulations
Soonpil Kang, James F. Kelly, Anthony P. Austin +1
This paper presents a multiscale modeling framework (MMF) to model moist atmospheric limited-area weather. The MMF resolves large-scale convection using a coarse grid while simulta…

Adversarial Perturbations of Physical Signals
Robert L. Bassett, Austin Van Dellen, Anthony P. Austin
We investigate the vulnerability of computer-vision-based signal classifiers to adversarial perturbations of their inputs, where the signals and perturbations are subject to physic…
