A new concept has been created for building a platform for design, operating and developing critical IT infrastructures for “big data”, as well as a number of new models, methods and tools for synthesizing and modeling neural network hardware and software structures that automate the functioning of IT infrastructure components, new methods for structured training of neural networks , tools for adapting programs to achieve the efficiency of parallel programming of systems on homogeneous and heterogeneous architectures, models and methods of parallel computing solutions in today's data center

The created scientific bases and regularities of electrochemical formation of ordered nano- and micro-level materials of hemotronics are based on a clear separation of the influence of the charge transport mechanism of the limiting stage of the electrochemical process on the stratification of the structure of the surface oxide and metal phases of the electrode. The structuring of semiconductor phases is governed by the ratio of gradients of the electric field and charge carriers in liquid and solid phases.

A theory has been developed for multi-tiered bandpass filters of a planar structure, its position is confirmed by measurements on existing experimental samples. On the basis of the established theoretical positions, new circuit design solutions for bandpass filters with different frequency characteristics have been created, which is reflected in the patent materials. It is established that three- resonator filters with a mixed cross-coupling K 13 = K m + K e , equal to zero (К 13 = 0), have two equidistantly located damping poles or a constant delay time.

The basic regularities of the physical nature of strength of directionally solidified eutectic alloys (LaB6-MeB2, B4C-MeB2, Ti-TiB, Mo-Si-B, etc.) have been defined by systematic studies of the influence of the nature of the matrix and reinforcing phases, their structural-geometric characteristics, and stress-strain state on the temperature dependence of mechanical characteristics of composite materials.

Statement and performance of the research under consideration are substantiated by: (1) vital necessity of support and strengthening of safety barriers in nuclear power engineering by passive methods heat removal; (2) availability of vaporization-and-condensation type (VCT) systems creation for heat removal and thermal shielding; (3) significant limitation of the noted R&D and absence of its implementation in nuclear power technologies; (4) extremely insufficient experimental data base as to core temperature mode in the SCW reactors of a new generation resulting in absence of reliable

A package of applied programs for calculating and designing a mobile robotic complex based on a chassis of high cross-country ability with a wheel-walking twin-rollers driver. Effective methods for solving a number of applied problems are proposed, in particular, analytical and numerical modelling of chassis’s dynamics during overcoming obstacles with comparable sizes; identification of loads applied to chassis’ parts by numerical methods or by values of corresponding sensors; predicting the residual life of parts under intense external loads.

A new theory of targeted activation of waste ("red muds") of alumina production has been created, and multifunctional water treatment reagents with a specified structure and clearly defined coagulation, sorption and biosorption properties have been obtained in the processes of removing inorganic and organic substances of various types and origin (heavy metals, dyes, active substances) from contaminated water.

Purpose of the work is design of methods and means for determination of transition’s probability of reconfigurable multiprocessor system (MS) aimed to control the complex objects. This transition can lead to dangerous state. Also as result of the work is enhance of system functioning results’ veracity. During exploitation due to the processors’ failures MS can went into dangerous state (that is state when is only one (any) of control functions can not be realized and without of those the control object went into dangerous state).

The aim of this research project was to study the asymptotic behavior of pseudo-regular functions and their analogues in stochastic analysis - generalized renewal processes, as well as applications of the results obtained to the theory of stochastic processes, statistics of stochastic processes, mathematical analysis and mathematical physics.
In this project:

Laws of energy induced diffusion phase-structural transformations in film functional-gradient materials with significantly different thermodynamic and crystal-chemical properties of the layers (V-Ag, Pd-Ho, Ni-Cu-Cr, etc.) were determined.
“Diffusion pump” effect was determined for investigated nanothickness materials: physical and chemical processes on outer surface thermodynamically determine diffusion phase formation in the bulk during energy impact in argon-, nitrogen-, oxygen-, hydrogen- containing atmospheres and in vacuum of 10-3 Pa, 10-7 Pa.
