Joseph Hart, Sandia National Laboratories, Hyper-Differential Sensitivity Analysis: Managing High Dimensional Uncertainty in Large-Scale Optimization

April 7 | 3:00 pm - 4:00 pm EDT

Large-scale optimization is ubiquitous in scientific and engineering applications. The end goal in most applications is the solution is a design, control, or inverse problem, constrained by complex high-fidelity models. Achieving this goal is challenging for many reasons, most notably,…

Bo Wang, Southern Methodist University, Fast and Accurate Simulations Of Time Domain Scattering Problem

August 25 | 3:00 pm - 4:00 pm EDT

We present a fast and accurate numerical method for the simulation of time domain¬†scattering problem. Both acoustic and electromagnetic scattering problems are discussed.¬†Nonreflecting boundary conditions (NRBCs) are used to truncate the problem. We first¬†derive analytic expressions for the underlying convolution…
