Localization of Rock Acoustic Emission Sources Based on a Spaced Sensors System Consisting of Two Combined Receivers and a Hydrophone
Marapulets Y., Shcherbina A., Solodchuk A., Mishchenko M.
The paper considers the results of experiments on localization of the sources of geoacoustic radiation generated in near-surface sedimentary rocks. Geoacoustic signals from sources were recorded by a spaced sensor system consisting of two combined receivers and a hydrophone. ...
Berlage Oscillator as a Mathematical Model of High-Frequency Geoacoustic Emission with One Dislocation Source
Sergienko D.F., Parovik R.I.
A mathematical model of high-frequency geoacoustic emission for a single dislocation radiation source is suggested in the papper. The mathematical model is a linear Berlage oscillator with non-constant coefficients whose solution is the Berlage function momentum. ...
