Colloquium

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Jose Castillo, San Diego State University, Computational Science Research Center ABSTRACT: It is well known that the inviscid Burgers equation poses several numerical challenges when used in modeling fluid flows and gas dynamics. The non-linear equation leads to sharp discontinuities or shocks as the initial condition evolves over […]

TIME: 2:00 PM LOCATION: GMCS 206D SPEAKER: Christos E. Papoutsellis, École Nationale des Ponts et Chaussées ABSTRACT: In this talk, I will present the numerical solution of the Serre–Green–Naghdi (SGN) model for the propagation of surface gravity waves. I will begin with a brief overview of the mathematical formulation of the water-wave problem and the […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Randall LeVeque, University of Washington ABSTRACT: The open source GeoClaw software (distributed as part of Clawpack) implements the two-dimensional shallow water equations (SWE) over topography in a well-balanced manner, and is widely used for modeling tsunamis, storm surge, river flooding, and other natural hazards over large spatial extents. […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Filippo Capolino, UC, Irvine, Electrical Engineering and Computer Science ABSTRACT: There are two classes of exceptional point degeneracies (EPDs): one related to coupled resonators and the other to coupled-mode waveguides. EPDs are observed among the eigenstates of such systems, i.e., in the eigenfrequencies for the first class and […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Wahid Bhimji, Lawrence Berkeley National Laboratory, Data and Analytics Group ABSTRACT: AI and Machine Learning are changing society. This is also true in science where these techniques have promise to change how things are done: making science is more productive and yields new discoveries. In this talk we […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Andy Wan, University of CA, Merced ABSTRACT: Many models from science and engineering possess fundamental structures which are important to preserve in order for accurate and stable long-term predictions. For instance, preserving conserved quantities, such as energy, mass and momentum, are fundamental in many physical systems. Moreover, preserving […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Meghnath Dhimal, Harvard University, T.H. Chan School of Public Health ABSTRACT: Global environmental change driven by global warming, land use change, rapid urbanization, and intensified human mobility is reshaping ecosystems and creating emerging and re-emerging health risks to population health. Vector Borne diseases (VBDs) are among the most […]
