The paper investigates a relevant applied problem associated with building decision support systems for critical information services. An original approach is proposed, based on neural network forecasting, within which a method of dynamic local approximation using neural network models has been developed. The principles of constructing and implementing the operational algorithm (under conditions of uncertainty of the external load profile) of a combined proactive system for managing computational resources are outlined. Experiments have been conducted that confirm the effectiveness of the method and the approach as a whole.

Formation of a capable and highly efficient team is the main task of personnel work at petrochemical enterprises, which are high-risk facilities. High requirements are imposed on the qualification of engineering and technical personnel of oil refineries. The process of selection of candidates for work in technical or engineering specialties is rather labor-intensive. Development of software for automation of personnel selection and employee attestation processes for JSC «Naftan» based on the model of key professional competencies will improve the procedure of hiring efficiency, will allow processing more applications of applicants and focusing on the best of them already at the initial stages.

The optical and strength properties of electron-irradiated films of a polyimide composition (polyimide PI2610) deposited on the surface of single-crystalline silicon wafers of the KDB-10 grade by centrifugation were studied. Irradiation with electrons with an energy of 5 MeV was carried out on a linear accelerator U-003 in the dose range 1·1014 – 2·1015 cm–2. It has been experimentally established that at an irradiation dose of Ф = 1∙1014 cm–2, relaxation of elastic stress fields in the polyimide film is observed, which is expressed in modification of the shape of bands with maxima at 1349 and 1700 cm–1, caused by vibrations of the C–N–Cst bond and the C=O double bond imide ring. Polyimide PI-2610 films on silicon are quite stable when irradiated with electrons. A noticeable transformation of the ATR spectrum at a dose of 2∙1015 cm–2 was observed only in the region of stretching vibrations of C–H and O–H bonds, which is due to radiation-induced processes on by-products of polyimide synthesis and residual solvents. No noticeable decrease in the intensity of absorption bands caused by vibrations of the skeleton of the aromatic ring, imide ring, single and double C–C and C–O bonds, and imide C=O bonds was observed.

This article formalizes the problem of semi-automatic construction of the contour of area objects from satellite multispectral images and presents a solution algorithm using PCA and Dijkstra's algorithm. The emphasis of the article is on optimizing PCA using annual matrices for images of the same class, as well as optimizing the Dijkstra algorithm using dynamic programming methods. The contour is considered as the boundary of an object, which can be used for its segmentation and classification. The semi-automatic contour accepts reference points specified by the operator. The formalization of the algorithm is completed.

A study was carried out of the electrodynamic response of an anisotropic medium over hydrocarbons under the influence of probing signals for pulsed and dual-frequency modes with a predominance of high-frequency signals. The characteristics of the geological profile above hydrocarbon deposits were studied using pulse signals depending on the carrier frequency and period of the radio pulse. For the dual-frequency signal mode, the dependences of the material and phase components of the surface impedance of the studied medium over oil and gas fields were modeled depending on the amplitude and frequency ratios. It has been established that an increase in the dielectric constant of the geological profile above the deposits leads to a decrease in resonance frequencies and the values of the absolute component of surface impedance Ż11. The revealed manifestations of anomalous effects expand information about the characteristics of the environment above deposits under the influence of pulsed electromagnetic waves and are of practical interest for exploratory geophysics. The results obtained can be used for electrical prospecting when creating equipment for detecting oil and gas fields.

The object of study is the morphological stability of the tip of a free dendrite in a supercooled melt of a pure substance. Areas of deep supercooling are considered: for nickel DT > 166 K, for copper – DT > 180 K. A distinctive feature of the processes being studied is the presence of two propagation velocities of small disturbances (velocities of “sound”). The dependences of these rates on the supercooling of the melt were determined. The periodic and coordinate-aperiodic modes of perturbation of the growth line have been studied in detail. For these stable regimes, the possibility of observing the same speed of the disturbance wave in two processes, differing from each other in the size of the spatial inhomogeneity of the background in front of the wave and the characteristic wave attenuation times, was discovered. It is shown that aperiodic instability appears if, after the passage of the wave front, the width of the growth line inhomogeneity zone decreases. The resonant excitation mode of the dendrite tip demonstrates important differences between the properties of the nickel and copper melts. First of all, this relates to the temperature dependences of the resonant frequency and the speed of a standing wave formed in the vicinity of the vertex. Numerical calculations are presented and graphic information is presented illustrating the patterns of growth of nickel and copper dendrites.

The optical and strength properties of Kapton polyimide films implanted with manganese ions with an energy of 40 keV and a dose of 5·1016 – 1·1017 cm–2 at a current density in the ion beam of 4 μA/cm2 have been studied. It has been experimentally established that during the process of ion implantation, modification of a thin nearsurface layer of polyimide occurs not only on the implanted side, but also on the reverse side of the film. Radiationstimulated modification of the back surface of the polyimide film leads to the formation of a surface layer up to 5 μm thick with increased microhardness. This may be due to the restructuring of metastable defects formed during the film manufacturing process and the simultaneous relaxation of elastic stresses in the surface layer. During the implantation process, a decrease in the intensity of absorption bands with maxima at ~ 2870 and ~ 2750 nm is observed, due to the evaporation of residual water under high vacuum conditions and reactions of residual solvent molecules, as well as radiation-induced processes on by-products of polyimide synthesis.

Nowadays, homogeneous objects clusters motion is one of the most important and rapidly developing computer vision and machine learning application. In this paper, we consider the crowd motion patterns determination by using motion maps that we calculate with FlowNet, a neural network examining motion of objects in a video sequence. This approach allows us to get information on the crowd direction and velocity with relation to other objects of scene, which plays the key role in behavior analysis and security establishment. Besides, we consider methods for preliminary video sequence processing, including frame combination, to estimate motion maps more precisely and improve the effectiveness of the dynamic scenes analysis.
