Pressure measurement: Electrical pressure transducers

Progress in Cardiovascular Diseases, 1963
Summary The principles of intravascular pressure detection and recording have been discussed. Accuracy of recording depends upon the dynamic response characteristics (frequency response and sensitivity), and the stability of the transducer system, as well as the response characteristics of the amplifier and recorder.

Ultrasonic pressure measurement in pressure vessels

Review of Scientific Instruments, 2014
Based on the reflected longitudinal wave, a new non-intrusive method for pressure measurement is proposed. The acoustoelastic theory and the thin-shell theory are introduced to develop the pressure measurement model in cylindrical pressure vessels. And a pressure measurement system is constructed to evaluate the effectiveness of the proposed method ...

Constant pressure molecular dynamics for molecular systems

, 1983
Technical aspects of the constant pressure molecular dynamics (MD) method proposed by Andersen and extended by Parrinello and Rahman to allow changes in the shape of the MD cell are discussed.

Peer Pressure and Manager Pressure in Organisations *

We study the interaction between horizontal (peer) and vertical (manager) social factors in workers’ motivation. In our setting, individuals work using open-plan desks. Using a natural experiment, we identify a sharp increase in workers’ productivity following the occupation of adjacent desks. We link this peer pressure effect to two key aspects of the

Pressure developed under pressure garment

British Journal of Plastic Surgery, 1993
To study how much pressure develops under a pressure garment, and how to obtain adequate effective pressure for scar treatment, we have used garments in combination with sponge and plastic plates in human volunteers. The pressures increased significantly when a sponge or sponge and plastic plate were used beneath the garment compared to pressures using
