MONITORING OF SEDIMENTARY ROCK GEOACOUSTIC EMISSION BY A LASER STRAINMETER-INTERFEROMETER AND BY A THREE-COMPONENT PIEZOELECTRICAL SEISMOMETER
Journal Title: Вестник КРАУНЦ. Физико-математические науки - Year 2017, Vol 4, Issue
Abstract
The results of complex geodeformation observations in Kamchatka are presented. A laser strainmeter-interferometer (developed at IKIR FEB RAS) and a three-component piezoelectrical seismometer, constructed by ZAO “Geoakustica” and provided by IMGiG FEB RAS within a joint research, were used as the registering systems. Signals, received simultaneously by different registration systems, were analyzed. Seismic signals from earthquakes, pulses with the frequency up to 100 Hz and higher-frequency geoacoustic signals, which had been registered by a system of spaced hydrophones at IKIR FEB RAS before, were detected.

THE CAUCHY PROBLEM FOR THE RICCATI EQUATION WITH VARIABLE POWER MEMORY AND NON-CONSTANT COEFFCIENTS
The Cauchy problem for the Riccati equation with non-constant coefficients and taking into account variable power memory is proposed. Power memory is defined by the operator of a fractional derivative of a variable order...
