Abstract: An auscultatory sound-or-vibration sensor electronic test signal applied to a sound generator generates an acoustic sound signal, responsive to which an auscultatory sound-or-vibration sensor in proximity to the sound generator generates a corresponding auscultatory sound signal. The auscultatory sound-or-vibration sensor electronic test signal incorporates a plurality of frequency components, each frequency component of which incorporates an integral number of wavelengths and is terminated following a duration of time corresponding to the integral number of wavelengths after that frequency component is applied to the corresponding sound generator. A determination of whether or not the auscultatory sound-or-vibration sensor is functioning properly is made responsive to an analysis of a Fourier Transform of the auscultatory sound signal.

Abstract: Membranes for membrane distillation (MD) and forward osmosis (FO) are provided with methods of manufacture and use thereof. The MD membrane comprises a microporous mat of electrospun nanofibers made of a nanocomposite comprising reduced graphene oxide dispersed in a hydrophobic polymer with their surface grafted with a silane coupling agent or with hydrophobic nanoparticles. The FO membrane comprises a microporous support layer and a rejection layer formed on one side of the support layer, wherein the support layer is a microporous mat of electrospun nanofibers made of a nanocomposite of hydrophilic nanoparticles dispersed in a hydrophilic polymer, and the rejection layer is made of nanocomposite of hydrophilic nanoparticles dispersed in a crosslinked meta-aramid of formula (I). There is also provided a process for treating a high-salinity and/or high-strength feed, such as fracking wastewater, comprising microfiltration or ultrafiltration, followed by forward osmosis, and then membrane distillation.

Abstract: A time-series array of noise data is generated from an inverse frequency transform of the product of the frequency spectrum of an auscultatory sound signal with an associated noise filter generated responsive to a cross-correlation of frequency spectra of auscultatory sound signals from adjacent auscultatory sound-or-vibration sensors on the torso of a test subject. Noise power within at least one range of frequencies of average of frequency spectra from a plurality of windows of the time-series array of noise data is compared with a threshold to determine whether or not the associated auscultatory sound-or-vibration sensor is excessively noisy. In one embodiment, the noise filter is generated by subtracting from unity, a unity-normalized cross-correlation of frequency spectra of the auscultatory sound signals, wherein the resulting values are clipped so as to be no less than an associated noise floor.
