[1] 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. We inverted fundamental mode Love and Rayleigh wave phase and group velocity maps for pdfs of crustal thickness and independently of verti...

We report an experimental study of traveling-wave convection patterns in a binary mixture of ethanol and water. We survey the patterns observed in a large aspect ratio cylindrical container over a broad range of Rayleigh numbers. It is found that disordered patterns observed immediately after travelingwave convection is initiated evolve toward organized multi-domain patterns, and that the natur...

The Middle-Chelif basin, in northwestern Algeria, is located a seismically active region. In its western part lies the El-Asnam fault, thrust fault responsible for several strong earthquakes. most important being earthquake (Ms = 7.3) of 1980. present study, ambient vibration data with single-station and array techniques were used to investigate dynamic properties ground estimate Vs30 structure...

The present investigation deals with the propagation of waves in a micropolar transversely isotropic layer. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitudes of displacements and microrotation were also obtained. Finally, the numerical solution was carried out for aluminium epoxy material and the dispersion curv...

The Sichuan-Yunnan region is located at the intersection between South China Block, Indian plate, and Tibet Plateau crisscrossed with deep large faults characterized by strong seismic activities extrusion of Tibetan Plateau. Here we employ 1-year continuous waveforms vertical component 89 broadband stations using noise tomography in this to evaluate velocity structure its implications. Through ...

Polymer coated gas-phase sensors using the classical Rayleigh-type surface acoustic wave (RSAW) mode showed higher sensitivity and larger dynamic range compared to bulk acoustic wave (BAW) sensors, being widely used in a variety of sensor systems for chemical and biological gas detection. Using Comsol Multiphysics software, we investigated a 2D finite element model of a Surface Acoustic Wave (S...

Dispersion curves to a oscillatory reaction-diffusion system with the selfconsistent flow have obtained by means of numerical calculations. The flow modulates the shape of dispersion curves and characteristics of traveling waves. The point of inflection which separates the dispersion curves into two branches corresponding to trigger and phase waves, moves according to the value of the advection...

The present article is devoted to a theoretical study on Love wave vibration in a pre-stressed fluid-saturated anisotropic porous viscoelastic medium embedded over an inhomogeneous isotropic half-space influenced by gravity. The expression of dispersion has been achieved with the help of mathematical tools such as variable separable method and Whittaker’s function’s expansion under certain boun...

In this paper, by using a quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, we present the corrected plasmon dispersion relation for graphene which includes a k quantum term arising from the collective electron density wave interference effects (which  is integer and constant and k is wave vector). The longitudinal ...

Passive seismic characterization is an environmentally friendly method to estimate the properties of subsurface. Among its applications, we find monitoring geothermal reservoirs. One key characteristic ensure a productive management these reservoirs degree fracture connectivity and evolution, as it affects flow fluids within formation. In this work, explore effects on Rayleigh wave velocity dis...
