Оптические характеристики термосферы и мезосферы
Шевцов Б. М., Пережогин А. Н., Середкин И. Н.
Используя лидарные сигналы на длинах волн 561 и 532 нм в диапазоне высот 30-400 км, путем решения обратной задачи восстанавливаем коэффициенты рассеяния света, соответствующие этим длинам волн, что позволяет сравнить оптические характеристики термосферы, мезосферы и верхней стратосферы и ...
Аппроксимация законов распределения времён ожидания форшоков на основе дробной модели деформационной активности
Шереметьева О.В,, Шевцов Б.М.
В статье рассматриваются два алгоритма построения последовательностей форшоков, связанных с главным событием заданной энергии, на основе ранее разработанной авторами статистической модели деформационного процесса. Для исследования используется каталог землетрясений КФ ЕГС РАН (01.01.1962 − 31. ...
Recording of atmospheric electrical potential gradient in the central part of Kamchatka peninsula
R. Akbashev, P. Firstov, N. Cherneva
Electrostatic fluxmeters are in operation at three sites in the region of Central Kamchatka depression to record the atmospheric electrical potential gradient (PG). ...

Observation of the State of the Near-surface Lithosphere Layer based on the Analysis of the Dynamics of the Geoacoustic Emission Signal Characteristics
Senkevich Y. I., Mishchenko M. A., Solodchuk A. A.
The main cause for the occurrence of seismic phenomena is associated with tectonic movements of the earth’s crust. Such displacements generate elastic waves propagating in the lithosphere. These waves are called geoacoustic emission. ...
Mathematical Model of the Formation of Geoacoustic Emission Zones in the Elastic Approximation of the Medium
Gapeev M.I., Solodchuk A.A
Geoacoustic emission is the emission of elastic waves by rocks as a result of their dynamic restructuring. Geoacoustic emission zones are areas of the Earth’s crust surface with relative deformations from to . ...
Mathematical Model of High-Frequency Geoacoustic Emission
Solodchuk A.A., Gapeev M.I., Sergienko D.F., Parovik R.I.
Geoacoustic emission is an indicator of the stress-strain state of the lithosphere, so it plays an important role in the development of methods for predicting strong earthquakes in seismically active regions such as Kamchatka. ...

Solution of a nonlocal boundary value problem of diffusion-convective transfer of radioactive substances in the lithosphere-atmosphere system
R.I. Parovik
The article studies a boundary value problem for describing non-local and nonstationary diffusion-convective transfer of radioactive material in the lithosphere-atmosphere system. ...
Dubovsky's Class of Mathematical Models for Describing Economic Cycles with Heredity Effects
D.V. Makarov, R.I. Parovik, R.I.Parovik, Z.H. Rakhmonov
The article is devoted to the study of economic cycles and crises, which are studied within the framework of the theory of N.D. Kondratiev long waves (K-waves). The object of the study is the fractional mathematical models of S. V. ...
Selkov's Dynamic System of Fractional Variable Order with Non-Constant Coefficients
R.I. Parovik
This article uses an approach based on the triad model–algorithm–program. The model is a nonlinear dynamic Selkov system with non-constant coefficients and fractional derivatives of the Gerasimov–Caputo type. ...
