Fully nonlinear inversion of fundamental mode surface waves for a global crustal model [PDF]
, 2007 We use neural networks to find 1-dimensional marginal probability density functions (pdfs) of global crustal parameters. The information content of the full posterior and prior pdfs can quantify the extent to which a parameter is constrained by the data.

Determination of wave speed and distensibility of flexible tubes using diameter and velocity [PDF]
, 2009 It is well accepted that wave speed is one of the key factors describing wave propagation in arteries. Local wave speed is directly related to the mechanical properties of the arterial wall and is widely used to determine the arterial distensibility ...

Effects of Particle Shape on the Shear Wave Velocity and Shear Modulus of 3D Printed Sand Analogs
Open Geomechanics, 2022 Isolating the effects of individual particle properties (e.g. shape, size, mineralogy, surface roughness) on the mechanical behavior of naturally occurring coarse-grained soils is a significant challenge in experimental studies.

Shear wave velocity-based evaluation of liquefaction resistance of in-situ sand with aging effects
Yantu gongcheng xuebao, 2023 The shear wave velocity is one of the commonly used parameters to evaluate liquefaction resistance of sandy soils. In this study, based on the initial liquefaction criterion-based shear wave velocity characterization model (i.e., the "Zhou-Chen model ...

Subsonic near-surface P-velocity and low S-velocity observations using propagator inversion [PDF]
, 2005 Detailed knowledge of near-surface P- and S-wave velocities is important for processing and interpreting multicomponent land seismic data because (1) the entire wavefield passes through and is influenced by the near-surface soil conditions, (2) both ...

Inner core composition paradox revealed by sound velocities of Fe and Fe-Si alloy
Nature Communications, 2022 The origin of the observed low shear wave velocity in the solid inner core is unclear. Here, the authors report shear wave velocities of iron and iron-silicon alloy under Earth’s core conditions by shock compression and find that neither the effect of ...
