We've also measured how the sound speed
changes at various depths beneath the seafloor, and crystal alignment doesn't explain why east-west sound waves travel faster when they move through rocks deeper into the plate.
As shown in Figure 7, there is a serious negative sound speed
gradient layer near the surface.
This rather slow expansion is the main reason for the absence of significant pressure gradients in the two-phase water mixture, despite the low sound speed
The sound speed
c is proportional to the slope u of the Goldstone sound mode c = uat/[??].

Fluorinert FC-43 (3M[TM]) was chosen for this study due to its low sound speed
(646 m/s) and relatively large (for a liquid) acoustic nonlinearity parameter [beta] (6.8-7.6) [10-13].
Thus, the higher the sound speed
the higher the incompressibility of the fluid.
Lately, I'm getting emailed news releases from Blair FitzGibbon, president of another PR firm called, Sound Speed
Such works are impossible to digitize--and not only because the "visual magma" is not translatable, but because many of Gehr's early films, including Serene Velocity; all of Dorsky's films; and all the Warhol silents must be shown at silent speed (16 or 18 frames per second), which is a third slower than sound speed
. (Although it is hardly remarked on, this is a problem in the digital exhibition of silent narrative films as well.) And currently, digital players and drives are set to run only at sound speed
, or 24 fps.
Delphinus claims it is the first company to introduce an automated whole breast ultrasound system to integrate ring transducer technology that captures reflection echoes from all directions around the breast and measures transmitted signals coming through the breast, depicted by a color analysis of sound speed
and attenuation values.
By measuring and combining the quantitative values of sound speed
and attenuation from signals that pass through tissues, a cross-sectional color image map is created using an established color spectrum, signifying the least to greatest relative tissue stiffness of the full volume of breast tissue.
here V is sound speed
in rotor's outside ring, 2R is diameter of outside ring.
