Design and Testing of Off-The-Shelf Electronic Components for an Acoustic Emission Structural Health Monitoring System Using Piezoelectric Sensors
… line driver. A charge amplifier converts a high impedance signal to a low impedance signal. A high pass filter attenuates the low frequency content of a signal, while a low pass filter attenuates the high frequency content of a signal. A line driver converts a low current signal to a high current …

Investigation of synthetic methods for preparation of 2<sup>o</sup>-amino derivatives of 5-amino- 1, 10-phenanthroline: Applications to Cu<sup>+2</sup> based impedance sensors
… interdigitated electrode array chips in standard impedance and impedance resonance-based Cu<sup>2+</sup> sensors. Potential applications include monitoring Cu<sup>2+</sup> leaching from anti-fouling coatings on ship hulls. The importance of the planned secondary alkyl amino derivatives will be to …

Correlation and real time classification of physiological streams for critical care monitoring.
… to determine the start and end of a multi-signal episode. The episode is then processed through a classifier based on clinical rules to determine a classification. The output of the algorithms has been shown, in a single use case study with 24 hours of patient data, to detect clinically …

Design of, and initial experiments with, a MIMO plate control testbed
… The sensors measure plate positions using a high impedance signal conditioning amplifier. The sixteen-channel design implements a band-pass filter to eliminate low- and high-frequency noise. The power amplification scheme chosen for the actuators uses low-gain amplifiers (~2.5 V/V) in series with …

Yeast-based impedance biodosimetry for retrospective assessment of radiation exposures
… exposures following radiological accidents using impedance biodosimetry. The radiation response of S. cerevisiae was examined by using cellular metabolic activity and impedance as a means to evaluate dose. A novel dosimeter design was developed to allow impedance measurements to be performed on …

PROCESSING AND CLASSIFICATION OF PHYSIOLOGICAL SIGNALS USING WAVELET TRANSFORM AND MACHINE LEARNING ALGORITHMS
Over the last century, physiological signals have been broadly analyzed and processed not only to assess the function of the human physiology, but also to better diagnose illnesses or injuries and provide treatment options for patients. In particular, Electrocardiogram (ECG), blood pressure (BP) …
