S-wave

S-wave

(ĕs′wāv′)
n.
A seismic wave that travels relatively quickly through the earth, causing the rocks it passes through to change shape, and the particles of the rocks to vibrate at right angles to the direction of wave propagation. S-waves can travel through solids but not through liquids or gases. Also called shear wave.

[S(econdary) wave, since it is the second type of wave, after the faster P-waves, to be detected by a seismograph after a seismic event.]

In this paper, we theoretically study tunneling conductance in ferromagnetic metal/normal metal/ferromagnetic superconductor (FM/NM/FSc) double junction where ferromagnetic superconductor (FS) is in spin-singlet s-wave pairing (SWP) state and has an exchange field [h.sub.s].
In these papers, the studies of the binary condensates were limited to the case of s-wave interaction, while a great deal of attention has been drawn recently to the dipolar BEC.
Using Quick Epicentre Determination (QED) location and Jeffreys and Bullen (1958) travel time tables, the teleseismic body wave data were appropriately windowed for one minute starting 10s before P-wave arrival or S-wave arrival.
Earthquakes generate various kinds of waves; one type has a back-and-forth motion and is called a shear wave, or S-wave. S-waves travelling through the Earth will bounce or reflect off material interfaces inside the Earth, arriving at different times depending on where they interact with these interfaces.
In which, [v.sub.p] is the P-wave velocity, [v.sub.s], the S-wave velocity, and [rho] the bulk density.
Finally, an original method for shear wave (S-wave) calibration of AE sensors will be presented.
* Direct reading of calculated P-wave and S-wave velocity.
CGGVeritas derives a host of geomechanical properties from migrated CDP gathers, including YoungEoACAOs Modulus, PoissonEoACAOs Ratio, and shear modulus, by first inverting the data for P- and S-wave velocities and density.
(5) Second, the very short interval from the beginning of each QRS to the beginning of the retrograde P wave (0.07 seconds) and the retrograde P wave's having a pseudo r' deflection in lead [V.sub.1] and a pseudo S-wave configuration in the inferior leads strongly favor A-V nodal reentrant tachycardia over A-V reciprocating tachycardia utilizing a bypass tract.
It added, however, that it did not detect the type of seismic wave called an S-wave usually seen in natural earthquakes.
On the other hand, seismic tomography provides the 3D distribution of the physical properties (P- and S-wave velocities) in the rock massif.
In several regions, such as south of the Indonesian island of Java or in the Coral Sea northeast of Australia, P-wave and S-wave images show broad, plumelike features rising from the base of the mantle but extending only halfway to Earth's surface.
