Cluster analysis of earthquake hypocenters in Azerbaijan and surrounding territories
Sergii Skurativskyi, Sergiy Mykulyak, Yuliya Semenova +1
The research focuses on seismic events that occurred in Azerbaijan and adjacent territories, regions known for strong seismic activity. We analyze a catalog of recorded earthquakes…
Approximation of Invariant Solutions to the Nonlinear Filtration Equation by Modified Pade Approximants
Sergii Skurativskyi, Sergiy Mykulyak, Inna Skurativska
This paper deals with a mathematical model for oil filtration in a porous medium and its self-similar and traveling wave regimes. The model consists of the equation for conservatio…
Cluster and statistical analysis of spatial earthquake patterns in the South Caucasus region
Sergii Skurativskyi, Sergiy Mykulyak, Yuliya Semenova +1
The Caucasus region is characterized by heterogeneous and strong seismicity as a result of collision between Arabian and Eurasian tectonic plates. A rich variety of seismic events…
Statistical properties of shear deformation of granular media and analogies with natural seismic processes
S. V. Mykulyak, V. V. Polyakovskyi, S. I Skurativskyi
In this paper, the process of shear deformation of the medium formed by the cubic grains is investigated experimentally. It is demonstrated that the deformation process is intermit…
Energy redistribution in hierarchical systems of oscillators
V. A. Danylenko, S. V. Mykulyak, S. I. Skurativskyi
The article deals with the mathematical model for media with hierarchical structure. Using the hamiltonian formalism, the dynamical system describing the state of hierarchically co…
