Unpinning the spiral waves by using parameter waves*
Chinese Physics B, 2021The spiral waves anchored to heterogeneous areas are more difficult to control and eliminate than freely rotating ones in homogenous mediums. To eliminate pinned spiral waves, the resistant force should be provided to resist the pinning force. Other than advection field, we introduce parametric wave to play the role of providing resistant force.

Cylindrical-Wave Reciprocity Parameter
The Journal of the Acoustical Society of America, 1960It cylindrical waves are propagated between the projector and the hydrophone in a reciprocity calibration, a cylindrical-wave reciprocity parameter Jc is needed for the hydrophone sensitivity computation. The parameter Jc would be used, for example, when the projector and hydrophone are both long lines and are closely spaced or in a self-reciprocity ...

Wave parameter gradients along the wave ray
Marine Geology, 1976Abstract Computer methods have been used to track selected deep-water waves along their orthogonals to the surf zone. Three bottom orbital parameters were computed at each step: diameter, maximum velocity and acceleration. These three parameters were then plotted along the several wave rays, thereby providing shoreward gradients. The three gradients

Submaximal Stimulation and F-Wave Parameters
Journal of Clinical Neurophysiology, 2008This study evaluates the effect of submaximal stimulation and varying stimulus rates on F-wave parameters.F-waves were recorded from the abductor pollicis brevis muscle from 3 normal subjects stimulating at 25%, 50%, and 75% intensity in comparison with supramaximal stimulation based on peak-to-peak compound muscle action potential amplitude.

Critical events in random wave trains that can lead to impact on offshore structures are addressed. Experience from model testing has shown that impact is correlated with steep and energetic waves, characterized by high crests, wave heights, orbital velocities, slope, or a combination of all.
