Research:
I considering myself a "systems guy." My research spans the many
related disciplines of dynamics, vibrations,
controls, analog and digital signal processing, autonomous system
health
monitoring, smart materials, acoustics, and structural acoustics.
The confluence of these related disciplines is often referred to
as research in smart structures, adaptive systems or
structures,
or active control. Specifically, my research has involved
development of sensors and actuators as well asnovel control algorithms
and approaches, investigation of new system health monitoring methods,
control development for biological systems, algorithm development for
signal classification using artificial neurlal networks and Bayesian
statistics.
Some current projects include:
- Development of noise classifiers for military use
- Thermoacoustic refrigeration
- Control development for joint motion simulators
- Development of transducers and controls for advanced energy
systems
- Nanoscale hysteresis modeling and control in precision motion
equipment
I have also founded the Sound,
Systems, and Structures Laboratory in the Department of
Mechanical
Engineering at the University of Pittsburgh. This
laboratory includes 1,000 square feet of bench space, state of the art
equipment, and an anechoic chamber facility with a volume of
approximately
5,000 cubic feet. Funding has been obtained from NSF, DARPA/Army,
SERDP, AFRL, NIOSH, Aerotech, Inc., and US Dept of Energy (NETL).
This section will be greatly expanded in
the
future....
