Colloquium - Bradley

Chaos, Artificial Intelligence and Design
Associate Professor and Chair, Department of Computer Science
11/20/2003
3:30pm-4:30pm

In this talk, I will present two nontraditional approaches to the art of engineering whose roots lie, respectively, in artificial intelligence and nonlinear dynamics. I will begin by describing several AI tools that automate meaningful parts of an engineer's job: analyzing data (FCDMF), modeling system dynamics (PRET), and designing controllers (Perfect Moment). Following a brief review of the operative mathematical theory and computational techniques, I will then use a variety of examples to demonstrate that chaos is not only interesting, but actually quite useful. These examples -- which are drawn from various areas of science, engineering, and even the performing arts -- include methods that extract topological properties from sparse, quantized data; spacecraft trajectories that require less fuel; tracking circuitry with wider lock ranges; flow-control techniques that use MEMS actuators to harness the "butterfly effect;" and chaotic choreographic variations.
