A Comprehensive Experimental Evaluation of Actively Controlled Piezoceramics with Positive Posistion Feedback for Structural Damping
(Virginia Tech, 2000-03-30)
This study evaluates the effectiveness of actively controlled piezoceramics with positive position feedback (PPF) for reducing structural vibrations. A comparison is made between active control with PPF and a parallel ...
Multi-Function LIDAR Sensors for Non-Contact Speed and Track Geometry Measurement in Rail Vehicles
(Virginia Tech, 2013-06-03)
A Doppler LIght Detection And Ranging (LIDAR or lidar) system is studied for the application of measuring train ground speed in a non-contacting manner, as an alternative to the current train speed measurement devices such ...
