Presenter: Chrysoula Tsogka, Professor, Applied Mathematics, UC Merced Description: In a strongly scattering medium, waves undergo multiple scattering that is usually seen as an obstacle to imaging. Time-reversal experiments show the opposite: waves re-emitted into the medium refocus on their source more sharply than in a homogeneous medium, because scattering makes the array appear larger […]
Join the UC Santa Cruz Baskin School of Engineering for a virtual information session on our Scientific Computing and Applied Mathematics (SciCAM) M.S. program. Discover our curriculum, research opportunities, application requirements, and career paths for graduates. A live Q&A session will follow the presentation. Registration is required.
Presenter: Anuj Kumar, Assistant Professor, UC Davis Description: Turbulent flows can transport heat and momentum much more efficiently than pure molecular diffusion alone. What flow structures enable this efficient transport and how can they sustain dissipation when diffusivity or viscosity is small? These questions are fundamental to understanding turbulence and have important applications in engineering. […]
We motivate, formulate, and solve several structured optimal transportation (OT) problems for learning and control. The field of OT had its inception in 1781, when Gaspard Monge sought the optimal map to transport mass from a given initial distribution to a desired terminal distribution. Both OT and its entropy-regularized variant, the Schrödinger bridge problem (SBP), […]
