Variations in the changes of the mean values of compression wave
velocities for gneisses diverge in a wide range ([V.sub.PR] = 1.95-5.24 km/s).

into liquid lead: (a) pressure; (b) velocity.
However, both speed values were much smaller than the estimated compression wave
speed of approximately 1500 m/s.
This relationship suggested that under the same backpressure, a higher in-cylinder pressure at EVO created a stronger compression wave
during the blow down phase.
When the compression waves
reach the metal plate, the velocity of detonation products changes from [u.sub.i] to [u.sub.m] which is equal to V.
Finally, using the data obtained, we can estimate the average velocity [V.sub.av] of the compression wave
propagating through the felt material.
Note that the strain level, at which the elastic modulus based on the compression wave
velocity is determined, is generally less than [10.sup.-4] ~ [10.sup.-3]% .
Simply put, what we hear is a compression wave
traveling through the air.
Using his hands to run along the strings, Close creates a longitudinal compression wave
, which is a similar sound to the vibration patterns that are produced when a finger is run around the edge of a glass, resulting in deep cello-like tones.

The site response models were constructed using different borehole profiles, shear and compression wave
velocity profiles, and the available geotechnical data of CPT and SPT.
Although information can be extracted from compression wave
(P-wave) data alone, the inclusion of shear waves (S-waves) can be used as an additional source of observations to further constrain and narrow uncertainty in the results.
