We investigate numerical solutions of linear ordinary and partial differential equations. Cauchy’s problem for ordinary equations of first and second order are generalized with fractional power of finite operator. Condition of regularization for the difference operator analogue of a fractional power is represented.
The results of Ionosonde data over Kamchatka during the emergence of D-layer at night
are discussed. At the same time, the spectra of the night sky are represented at this period using a spectrum analyzer installed on Lidar Station of IKIR FEB RAS.
On the example of the local powergrid of Kamchatka shows the relationship between the magnitude of industrial current harmonics and variations of Earth’s magnetic field. Shows dependence of mechanism of geomagnetically induced currents creation from topology of powergrid.
Considered a model of large-scale magneto-convection in a roteting spherical shell. Velocity expressed of the one of the modes of free oscillation of a viscous conduction fluid in the shell. The stationary modes of convection were found. An ability of the dynamo was approved in this model.
The paper presents the results of numerical modeling of phase trajectories of the dynamical system Rikitake. Parameters of system and initial conditions at the case of doubling cascade mode are showen.
We consider a model of subdiffusion radon without advection. With the help of the Green’s function found a solution model. It is shown that it is a generalization of the previously known classical solutions.
In this paper we study the nonlocal effects of plastic deformation (shear) flow in the
subduction zone of the Kuril-Kamchatka arc based on a statistical model cite APS,
constructed according to the catalog of seismic moment tensor cite GCMT for the period
1976 — 2005.
The sparse approximation is a powerful instrument for time-and-frequency signal analysis. This publication outlines use of matching pursuit method for finding impulses in geoacoustic emission signals. Designed algorithm was tested on actual data.
This article reviews the methods of application of learning software. Conduct research shows that using a computer on a geometry lesson develops skills of students, making the learning process more effective.
