Rethinking the Mathematics of Decisions in Energy and Transportation Systems Seminar @ Mergenthaler Hall, Room 111
Mar 25 @ 3:30 pm – 4:30 pm

SI Leadership Council member Sauleh Siddiqui is the guest-lecturer of the Mar-25 E2SHI seminar on how mathematics can be used to solve today’s big challenges in energy, climate and urbanization. Dr. Siddiqui will discuss a modeling framework that provides insight for better intervention in energy and transportation systems. More details here.

The seminar is open to the public.

Modeling Cyclone Risk and Seismic Building Vulnerability in Central America and the Caribbean @ Hackerman Hall B-17
Oct 8 @ 12:00 pm – 1:00 pm

Graduate Seminar: Modeling Cyclone Risk and Seismic Building Vulnerability in Central America and the Caribbean

This seminar will introduce two research projects applied to the Country Disaster Risk Profiles initiative of the World Bank: a hurricane hazard model and a probabilistic seismic vulnerability tool (PSVT). The windstorm hazard model is a novel approach which yields characterizations of windstorm activity (rate of occurrence, trajectory and spatial wind field) in the Central American region for use in natural risk assessment. The generative mechanism of storms is formulated as a superposition of stochastic processes whose joint opera;on yields synthetic cyclones activity in the region. The outcomes of the model match observed data acceptably well. A brief reference to the risk estimation procedure will be offered. Vulnerability functions estimate building damage caused by an acting hazard intensity. The PSVT is a software tool for creating vulnerability functions for seismic risk analysis. The approach estimates structural response of user-defined models subjected to ground acceleration signals integrating the equations of motion. Ground signals are realizations of random process models of site–specific ground motion hazard.
