This paper considers basic element of device of energy storage which is a piezoelectric generator (PEG) of cylindrical form with the attached inertial mass. A finite element modeling of the device operation is carried out during active load in the external circuit. The main purpose of the operation is to compare the output potential and frequency characteristics of the device known in the literature models of systems with concentrated parameters. On the basis of these models, we can receive the analytical dependence of parameters of PEG with its geometric characteristics and mechanical properties of the used materials. However, the question of the range of applicability of these formulas is still open. In this paper, based on the numerical analysis of finite element models of PEG in package ANSYS, we obtained comparison with the analytical formulas that show the values of some parameters of simplified models and set the boundaries of their applicability.

The article is devoted to mathematical modeling of high frequency electrothermic of thermoplastics in relation to a technological system in the form of the component plate, including electrodes, insulators, the processed material, and the study of the influence of termoisolation on heating of the thermoplastic. In the article the mathematical model in the form of a system of nonstationary heat transfer in considering the internal heat sources with different boundary conditions and delivers its software. 
The software provided in article enables to study the influence of geometrical and electrophysical parameters of technological systems of high-frequency heating of the thermoplastic. In this article the results of research of influence of termoisolation on the nature of the heating of the thermoplastic. Based on the calculations presented in numerical and graphic kind, identified the following areas of heating polymer: uniform heating, regional zones of thermal influence of insulators. Heat-affected zone is characterized by depth and temperature of the contacting surfaces. The thickness increase of insulators over a certain value does not change the zone of thermal influence of insulators, which allows to speak about effective from the energy point of view of the thickness of the insulator, the excess of which increase energy consumption, time of heating of the polymer.
Conclusion is made according to result of the study about the necessity of the presence and settings termoisolations when building technological processes electrothermic of polymers. The developed software allows a new approach to the study of the RF heating, ensuring minimal energy consumption while ensuring uniform heating details.

The quantum and chemical simulation (HF/MP2, cc-pVDZ basis) of diphenyl-2,2',4,4'-tetraamine (DPTA) molecule properties allows to determine the its thin film pyroelectric properties since hydrogen bonds between molecules in the film are weaker than intramolecular bonds. The study of a DPTA photosensitive pyroelectric film microstructure enables one to assume that the dipole moment of the needle-shaped crystallines densely stacked and extended along a film surface is aligned perpendicularly to the surface. The possibility of the reproduced control for DPTA properties may be used when producing the most effective pyroelectric film for photodetectors in infrared wavelength range.

In the article results of theoretical researches of the rotor scatterer of fertilizers are resulted. For elimination of adverse conditions shock interactings of particles of fertilizers with rotor vanes, possibility of application of curvilinear vanes is observed. The forces acting on a particle which moves on a curvilinear vane are justified.

Relative orientation of the aerial views is the fundamental task of the photogrammetry. The final results depends on the accuracy and reliability of its solving, characterizing the spatial position of the photographed object (area).
Two groups of the elements of the relative orientation found their industrial application in our country (then ERO). However they don’t use up all the possible combinations of the corner pieces res ipsa loquitur and also between the photogrammes. Moreover it is known that in both systems of the relative orientation of the aerial views (base and linear-angular) visible correlation of the mistakes of the ERO are found, which leads to the additional of the route trough model within the coordinate space XY and XZ.
One of the possible alternative variants of the application within the group ERO of another corner piece is examined in this article. Five elements of the relative orientation of the aerial views are presented on the left view of the stereo mate as two angles: transverse inclination angle ω1 and longitudinal slope α1, and two angles (α1 and χ2) on the right and the azimuth of the direction of the basis of the design τ. Such a diviosn of the ERO has reduced much the correlation between the mistakes of the angle elements. However other variants are possible (e.g., τ, υ, χ1, α2 and ω2).
To calculate the photogrammetry co-ordinates of the general formula of the straight photogrammetry mark is proposed, which can be used both for the aerial shots in any direction and for the shooting from the points of the earth surface.
