Shear Wave Elastography Based on Noise Correlation and Time Reversal

open access: yesFrontiers in Physics, 2021
Shear wave elastography (SWE) relies on the generation and tracking of coherent shear waves to image the tissue's shear elasticity. Recent technological developments have allowed SWE to be implemented in commercial ultrasound and magnetic resonance ...

Evaluation indicators of saturation on partially saturated sand induced by microbial gas

open access: yesCase Studies in Construction Materials, 2022
The induced partial saturation (IPS) technique introduces a certain amount of air/gas into soil voids to mitigate sand liquefaction. The microbial desaturation method utilises biological metabolic processes which are good for environmental protection and

Effects of cyclic loading on lateral bearing capacity of single pile in silty seabed

open access: yesYantu gongcheng xuebao
Under larger wave loading, the bearing capacity of marine single pile foundation will be reduced, even instability occurs. A series of undrained shear triaxial tests on the remolded marine silt in Hangzhou Bay are carried out by means of the GDS triaxial

Influencing Factors of Shear Wave Radiation of a Dipole Source in a Fluid-Filled Borehole

open access: yesEnergies, 2022
In shear wave far detection logging, dipole-source radiation is the main factor influencing the amplitude of the reflected shear waves. In this paper, a method is derived with the far-field asymptotic solution to calculate the dipole-source radiation of ...

The evolution of mode-2 internal solitary waves modulated by background shear currents [PDF]

open access: yesNonlinear Processes in Geophysics, 2018
The evolution of mode-2 internal solitary waves (ISWs) modulated by background shear currents was investigated numerically. The mode-2 ISW was generated by the lock-release method, and the background shear current was initialized after the mode-2 ISW ...
