Our speaker will be Joe Zbilut of Rush University.

Dr. Zbilut's focus is physiologic research related to nonlinear dynamics. Working with colleagues in physiology, biophysics, and medicine, he has performed considerable research into the identification of rhythms and patterns in a variety of systems. Recognition of such "patterns" in complex systems provides unique challenges. Among the difficulties include:

1. lack of stationarity,
2. insufficient data length,
3. noise effects, and
4. inadequacy of algorithms for the calculation of chaotic invariants of real systems.

In collaboration with Dr. Charles Webber of Loyola University Chicago, Dr. Zbilut has developed a technique of recurrence quantification analysis (RQA) which overcomes many of these difficulties. At the same time, he has developed a model of chaos ("nondeterministic") which is unique in its emphasis on the importance of "noise" and its effects on deterministic processes as seen in physics, biology, psychology and sociology, and has implications for cognitive theory, natural neural nets, as well as organizational behavior.
