This seminar is devoted to fast, accurate algorithms in numerical analysis and signal processing. Conversation and collaboration among the groups is a particular goal. Pseudospectral and high-order finite difference methods, including but not limited to their use with irregular geometries and material interfaces. The sessions will be informal and interactive. Presentations will be about work in progress as well as established results.
Visitors are most welcome.
Graduate students may receive one credit for registering and attending. Regular meetings are in the applied math conference room, ECOT 226, on Tuesdays from 3-4pm. This research examines the use of wavelet-based lossy coding for the compression of turbulence data. The primary target is the compression of data produced by numerical simulations. The computer systems used for the simulations are becoming sufficiently fast that the output of intermediate results can significantly impact the performance of the simulation.
