Damping of intraocular pressure fluctuations
Clinical & Experimental Ophthalmology, 2012AbstractBackground: There is increasing evidence that relatively rapid spikes in intraocular pressure may contribute to axonal damage in glaucoma. The present study seeks to quantify the ability of a compressible damping element (a simple air bubble) to reduce intraocular pressure fluctuations induced by a known change in intraocular fluid volume ...

Pressure Sensitive Paint for Acoustic Pressure Fluctuations
Noise Control and Acoustics, 2005Full-field luminescent pressure sensors are commonly referred to as Pressure Sensitive Paint (PSP). In this paper, the suitability of PSP for the detection of acoustic pressure fluctuations is evaluated. Single point measurements utilizing a photomultiplier tube are performed in an acoustic plane wave tube capable of generating pressure levels up to ...

Physica, 1973
Abstract The old problem of pressure fluctuations is analyzed in terms of three characteristic times: (1) the duration of a molecular collision with the wall, (2) the time between successive collisions by a specific molecule, and (3) the integrating time of the pressure-measuring instrument.

Proceedings of SPE Production Operations Symposium, 1985
ABSTRACT The Pressure Fluctuating Tool (PFT) utilizes a fluidic oscillator to create pulsating pressure for breaking down perforations. The maximum pressure fluctuations produced by the oscillator can be as great as 1500 psi (10,300 kPa) above and below downhole ambient pressure with frequency ranging from 140 to 160 cycles per second ...

The discrimination of blood pressure fluctuations
Biological Psychology, 1979Two studies are described in which volunteers were trained to distinguish between displays contingent on or independent of blood pressure fluctuations. The latter were monitored with pulse transit time (TT). In Experiment 1, subjects were required to choose between TV displays that either reflected instantaneous TT or variations recorded a few minutes ...

Pressure fluctuations on gates
Journal of Hydraulic Research, 1989Mean and fluctuating pressures on various geometries of vertical-lift gates have been measured and analysed. The influence of various hydraulic parameters and the magnitude of the gate opening on mean and r.m.s. pressure fluctuations and their spatial correlations has been investigated.
