Spectra of mantle shear wave velocity structure [PDF]

open access: yesGeophysical Journal International, 1992
We applied the stochastic method of Gudmundsson, Davies & Clayton (1990) (which was applied to ISC P-wave data) to teleseismic ISC S-wave data to obtain an independent estimate of mantle structure.

Simulation of Optical Coherence Elastography in Agar Based on Finite Element Analysis [PDF]

open access: yesE3S Web of Conferences, 2021
The finite element method is used to simulate the optical coherent elastic imaging in Agar. The shear wave velocity in Agar was measured by ARF-OCE system, and then the Agar model was established by finite element method, and then the shear wave velocity

Shear Wave Velocity Estimation Using the Real-Time Curve Tracing Method in Ultrasound Elastography

open access: yesApplied Sciences, 2021
The estimation of shear wave velocity is very important in ultrasonic shear wave elasticity imaging (SWEI). Since the stability and accuracy of ultrasonic testing equipment have been greatly improved, in order to further improve the accuracy of shear ...

Area Covered for Shear Wave Velocity Calculation Affects the Shear Wave Velocity Values [PDF]

open access: yesJournal of Diagnostic Medical Sonography, 2019
Although ultrasound elastography is established as a reliable and valid tool for assessment of skeletal muscles, guidelines around the technical specifications, data selection, and acquisition parameters still lack consensus. One such parameter is the use of the quantification box (Q-box) that calculates the shear wave velocity/modulus, within a ...

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
