Flow field behind a complex total pressure distortion screen
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2019The flow field behind a complex total pressure distortion screen is investigated experimentally and numerically. The distortion screen is designed using an established design methodology and fabricated by water-jet cutting technique.

Influence of chest wall distortion on esophageal pressure
Journal of Applied Physiology, 1983 The caudocephalad profile of esophageal pressure swings was studied in 10 preterm and 5 full-term infants, and the effect of chest wall distortion on esophageal pressure swings was analyzed in 12 preterm infants. Esophageal pressure was measured with a fluid-filled catheter, tidal volume with a pneumotachograph, mouth pressure with a face mask and ...

Accurate estimation of tube-induced distortion effects on wind pressure measurements
Journal of Wind Engineering and Industrial Aerodynamics, 2019Pressure signals are commonly measured by tube-transducer systems which may result in significant distortion effects on the measurements. Although many studies have been conducted on the correction of distorted pressure records, there is a lack of ...

Computer Detection of Distortion in Arterial Pressure Signals
IEEE Transactions on Biomedical Engineering, 1974An application of the mathematical concept of curvature to the detection of distortion in arterial pressure signals is described. Curvature is defined and examples of digitally filtered pressure tracings show the relationship between curvature and the degree of damping. Even though curvature is also a function of the cardiovascular system producing the

Distorted hcp structure of zinc under pressure
Physical Review B, 1992Results of c/a variation under pressure for zinc from total-energy calculations that use first-principles linearized-muffin-tin-orbital calculations are presented. c/a decreases with compression and is found to change slope around V/${\mathit{V}}_{0}$\ensuremath{\approxeq}0.92, to approach the ideal value of c/a=1.63.
