Colloquia

TIME: 3:30 PM LOCATION: EIS 104 SPEAKER: Sandrine T. Rakotonarivo, Marine Physical Laboratory, Scripps Institute of Oceanography, University of California, San Diego ABSTRACT: This talk will present different strategies for monitoring of elastic structures using acoustics and ultrasound in the context of non-destructive testing, structural health monitoring and underwater acoustics. The development of localization and […]

TIME: 10:00 AM LOCATION: Dean’s Conference Room, ENG 203E SPEAKER: Juan D. Colmenares, Mark Kostuk, Federico Halpern, Akshay Deshpande and Pranav Puthan, DIII-D National Fusion Facility, General Atomics ABSTRACT: General Atomics (GA) has been at the forefront of fusion energy research for more than 50 years and operates the DIII-D National Fusion Facility for the […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Gregory Holland, Chemistry & Biochemistry, San Diego State University ABSTRACT: Over 300 million years spiders have evolved to produce seven different silk types and one glue-like substance. Spider silks are comprised almost entirely of protein and are used for a diverse range of applications including web construction, egg […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Charles-Gerard Lucas, Mathematics & Statistics, San Diego State University ABSTRACT: Scale invariance is a versatile signal processing paradigm that appears in various real-world applications and can be formalised by self-similarity. However, most practical studies have so far remained univariate, limiting themselves to analyse the different components of the […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Tharm Ratnarajah, Electrical & Computer Engineering, San Diego State University ABSTRACT: In federated learning (FL), model weights must be updated at local users and the base station (BS) or server. These weights are subjected to uplink (UL) and downlink (DL) transmission errors due to the limited reliability of […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Patrick Shoemaker, Computational Science Research Center, San Diego State University ABSTRACT: I describe computational models for how insects detect various classes of motion observed in their visual fields, based on temporally-varying signals from their photoreceptors. Early work was aimed at modeling a fundamental operation involving signals from neighboring […]

TIME: 3:30 PM LOCATION: Virtual Zoom Seminar SPEAKER: Vanessa Lopez-Marrero, Computational Scientist, Brookhaven National Laboratory ABSTRACT: Optimal transport, broadly defined, deals with the problem of minimizing the cost of transporting one (probability) measure to another. It is of interest in a range of subjects such as probability theory, optimization, and partial differential equations, among others. […]

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Feng-Bin Wang, Natural Science, Chang Gung University ABSTRACT: West Nile virus (WNv) is a mosquito-borne disease caused by Flavivirus. To investigate the combined effects of vertical transmission, temperature-dependent incubation periods and environmental heterogeneity on the transmission of WNv, we develop a delay differential system with stage-structure and time-varying […]
