Deformation processes in media with fractal structure have been studied. At present, research on the construction of mathematical methods and models of interconnected deformation-relaxation and heatmass transfer processes in environments with a fractal structure is at an early stage. There are a number of unsolved problems, in particular, the problem of correct and physically meaningful setting of initial and boundary conditions for nonlocal mathematical models of nonequilibrium processes in environments with fractal structure remains unsolved.

Purpose. The aim of the investigation is optimization monitoring of spatial displacements by GNSS and selection of minimal intervals of GNSS observations with given accuracy parameters. Methodology. For simulate the monitoring process on a real object tested network GNSS vectors with different lengths were installed. The network consisted of 4 points where two-frequency GNSS receivers were installed.

The processes of consolidation, deconsolidation, phase transitions and destructions in the terms of internal structures of the Earth аre studied on the base of non-linear theory of deformable solid bodies.  It is shown that the loss of stability of equilibrium state can precede to the processes of deconsolidation, phase transitions and destructions on geometric form change (structural instability).

The results of long-term studies of landslide processes in the areas of operation of pumped storage power plant with the help of modern GNSS technologies are considered. The presence of deformation of the earth's surface, both in terms in plane and vertical, is revealed. Displacement of some points is a closed-return trajectory and not exceed a few millimeters. Another part of the points is characterized by the horizontal displacements with the presence of returning movements.

The mechanisms of laser forming are analyzed. The experimental result are presented. Treatment recommendation of carbon steel 65Г and stainless steel 12Х18Н10Т are presented. The conditions and peculiarities of laser forming of low-carbon steel disks are explored.

Purpose. The aim of the research is the analysis of integrated observations of parameters of physical fields in the CSG of Transcarpathia, the establishment of the space-time dependence of observable quantities, identify their characteristics and connections of these fields with the geodynamic situation in the region to build a geomechanical model of the system of Transcarpathia, the process of accumulation and release of energy of elastic-deformation processes.  Methodology.
