In a second study conducted in 30 volunteers, shear wave propagation was measured.
The topics include observing the magnetic Compton profile of the interface-controlled cobalt/palladium multilayer, adsorption and sensitizing properties of azobenzenes having different numbers of silhyl-anchor groups in dye-sensitized solar cells, random-access multilevel storage in phase change memory by staircase-like pulse programming, a simulator to apply a shear wave velocity measurement system to arbitrary tissue elasticity distribution, the model feedback control system for a class of non-minimum phase systems, and a dicode signaling scheme for capacitively coupled interfaces.
The shear waves travel perpendicular to the direction of the push pulse, and shear wave speed correlates to tissue stiffness.
The shear wave travels through the solid snow and the longitudinal wave travel through the pore space as well as solid snow structure.
The transducer range has also been improved and extended to include shear wave transducers for testing Poisson's ratio and modulus of elasticity, exponential transducers for rough surfaces and higher frequency transducers up to 500 kHz for rock and ceramics testing.
In multicomponent data shear wave splitting can be observed.
s] in the soil is generally decoupled using a Helmholtz decomposition, which results in a set of uncoupled partial differential equations representing the longitudinal and shear wave propagation.
Then the focus turns to Portland concrete pavement, and such aspects as physical properties of rapid-setting concrete using ultra-fine fly ash, repairing longitudinal joints and cracks, and estimating the compression strength of concrete using shear wave velocity.
the group velocity is less than the shear wave velocity in the upper mantle.
Initiate a demonstration project on the ultrasonic shear wave transducer for use in identifying defects in concrete.
Finally, ground response analysis was performed using 1-D shear wave propagation analysis to develop the design response spectra.
