Maximizing the energy of surface wave and diminishing the effect of lateral inhomogenousness in the multichannel analysis of the surface wave (MASW)

Science and Technology Development Journal - Natural Sciences, 2019
Multichannel analysis of surface wave (MASW) is one of the novel seismic methods in geophysic field in Vietnam. MASW is able to survey the stiffness of the soil environment under the ground via the shear-wave velocity VS by analyzing the spectral image of surface wave.

A probabilistic full waveform inversion of surface waves

Geophysical Prospecting, Volume 72, Issue 9, Page 3448-3473, November 2024.
Abstract Over the past decades, surface wave methods have been routinely employed to retrieve the physical characteristics of the first tens of meters of the subsurface, particularly the shear wave velocity profiles. Traditional methods rely on the application of the multichannel analysis of surface waves to invert the fundamental and higher modes of ...

Notranja oksidacija Cu-C in Ag-C kompozitov [PDF]

, 2012
The internal oxidation in copper-carbon and silver-carbon composites occurs when they are exposed to air or oxygen at high temperature. Solubility of carbon in copper or in silver is very low.

Application of Surface wave methods for seismic site characterization [PDF]

, 2011
Surface-wave dispersion analysis is widely used in geophysics to infer a shear wave velocity model of the subsoil for a wide variety of applications. A shear-wave velocity model is obtained from the solution of an inverse problem based on the surface ...

Integration of ground geophysical methods to characterize near‐surface aquifer zones within an active mine

Near Surface Geophysics, Volume 22, Issue 5, Page 521-538, October 2024.
Abstract Understanding near‐surface groundwater storage, flow patterns, surface and groundwater interactions in mining areas can assist in making mining more efficient and profitable. This is especially important in opencast mines affected by water inflows that may negatively affect production and increase mining costs. We map and characterize the near‐

Slope failure remediation using constrained horizontal‐to‐vertical spectral ratio inversion techniques

Geophysical Prospecting, Volume 72, Issue 8, Page 3157-3167, October 2024.
Abstract Slope failure rates may be exacerbated by increased precipitation patterns associated with climate change. Such events are extremely disruptive for local communities affected. Rapid engineering remediation solutions generally require immediate site characterization, including information on depth to intact bedrock and groundwater conditions ...
