Методика выделения информативных признаков в сигналах геоакустической эмиссии

open access: yesИнформатика и автоматизация, 2019
Исследования геоакустической эмиссии в сейсмоактивном регионе на Камчатке показывают, что при подготовке землетрясений и последующей релаксации поля локальных напряжений в пункте наблюдений в геоакустических сигналах возникают ярко выраженные импульсные ...

Diagnostic study of geomagnetic storm-induced ionospheric changes over very low-frequency signal propagation paths in the mid-latitude D region [PDF]

open access: yesAnnales Geophysicae, 2022
We performed a diagnostic study of geomagnetic storm-induced disturbances that are coupled to the mid-latitude D region by quantifying the propagation characteristics of very low-frequency (VLF) radio signals from transmitters located in Cumbria, UK ...

The Speed of Gravity in General Relativity and Theoretical Interpretation of the Jovian Deflection Experiment [PDF]

open access: yes, 2003
Recent measurements of the propagation of the quasar's radio signal past Jupiter are directly sensitive to the time-dependent effect from the geometric sector of general relativity which is proportional to the speed of propagation of gravity but not the ...

Development of a methodology to estimate a region and waiting period for strong Kamchatka earthquakes based on seismic and ionospheric predictive signs [PDF]

open access: yesE3S Web of Conferences, 2019
In this paper, an attempt is made to combine seismological and ionospheric predictive signs formed on the eve of earthquakes in order to develop a methodology for assessing the region and the time period of waiting for strong Kamchatka earthquakes with ...

Measuring the Impact of Beamwidth and Bandwidth on the Wide-Sense Stationarity of Millimeter-Wave Channels

open access: yesIEEE Open Journal of the Communications Society, 2023
If a wireless channel is said wide-sense stationary (WSS), the mean and autocorrelation of its small-scale fading are position invariant. This occurs when the channel is rich in propagation paths – their complex summation averages out any position-

Galactic synchrotron emission with cosmic ray propagation models

open access: yes, 2013
Cosmic-ray (CR) leptons produce radio synchrotron radiation by gyrating in interstellar magnetic fields (B-field). Details of B-fields, CR electron distributions and propagation are still uncertain.
