... limitations of many commercial piezoelectric accelerometers. To alleviate this difficulty, we present a low-frequency resonance accelerometer to capture extremely low speed rolling bearing faults. The design details are reported in this paper. With this new sensor, the resonance demodulation technique can...

...S. M. Yang; G. J. Sheu It has been stated that a uniform rotating shaft in the Rayleigh beam model has only a finite number of critical speeds and precession modes. This paper presents a controller design of optimal sensor/actuator location and feedback gain for steady state unbalance response...

.... This paper shows that the volume displacement of a vibrating beam can be measured through the use of a set of localized PVDF sensors each spanning only an area of interest. Summation of the volume displacements measured by these sensors would yield the total beam volume displacement. In this application...
