System Identification and Simulation of Linear and Nonlinear Systems
Automotive systems and component
behavior, e.g., polyurethane
foam, car seats, seat-occupant systems.
Nonlinear behavior of structures and
materials and interactions between viscoelastic materials and structures:
modeling, excitation for identifying model structure and for robust parameter estimation.
Prediction and simulation of interior
and exterior noise and vibration, with applications to engines, ground and
air vehicles, and buildings.
Monitoring of Machinery
Monitoring of component condition
in machines, e.g., pumps, compressors, rotating machinery.
Engineering (PBE) and Sound Quality (SQ)
Psychology and Engineering partnership of 15-20 faculty studying how people
are affected by engineered products and systems, with the aim of optimizing
machinery performance and effects on people. Group studies a wide
range of sensory input: sound, images, temperature and humidity, air-quality
(smell), touch, and speech.
SQ: My contribution to the
PBE research. Quantifying machinery noise signal characteristics that contribute
to a person's perception of its sound quality. Developing tools for engineers
to enable effective sound design of machinery. Applying
psychoacoustics research to environmental noise and community
impact assessment which includes sleep disturbance and annoyance.
and Signal Processing
Analysis of infant laughter to
monitor developmental changes.
Array techniques for noise source
Use of thin film sensors for real-time measurement of modal interactions.
