Physical principles of micro- and nanostructured states in surface layers were determined.

The main result of the work is the scientific conception of formation in α-Fe and it’s alloys nano- and submicrostructures under severe plastic deformation by friction (SPDF) in gas atmosphere (argon, air, ammonia). This original new method allows one to refine grain structure down to nanometre scale together with modifying the surface by dopant element.  Minimum strain e necessary to produce 100 nm sized α-Fe grained structure was estimated to be about 10 with high strain rate (έ>10² s^-1) in dynamic recrystallization condition.

First in the identical loading conditions the mechanical parameters such as Young's modulus Е, microhardness HV and nanohardness Hh, plasticity characteristics dH »dA, yield stress s0,2, temperature range of ductile-brittle transition, fracture toughness K1c, of intermetallics on the basis of aluminium, wich were absent in reference books till now, and the features of their deformation and destructions on nanо- and microlevels are determined.

As the result of research work a comparative analysis of existing security systems of microprocessor-based systems was made with aim to identify their disadvantages and improvement prospects. Existing microcontrollers were explore with aim to protection from readers on current consumption are researched and to determine the real security of high end microcontrollers and suggest ways to improve it. The algorithm of discrete wavelet analysis and spectral analysis in polar coordinates was further developed.

Working out of principles of construction and methods of implementation of mobile broadband access systems of a millimeter wave band for maintenance of high-speed access of users to ІР-networks data transfers under condition of maintenance of the secured quality of giving of services was a research work main objective.

The theoretical basis for the construction of telecommunications radio networks which do not require fixed infrastructure and consist of fixed and mobile subscribers has been established. The main scope of the work lies in the use of knowledge processing technologies for resource management processes of radio models at different OSI layers, which will provide the ability to self-organizing as well as functioning in uncertain conditions.

Scientific interest in noble metals nanoparticles (NPs) and nanostructured metal surfaces formed by their deposition is caused by their unique physical properties, including surface enhancement of linear and nonlinear optical phenomena in the media in contact with such nanostructures. Morphological characteristics of NPs determine their catalytic, sensor, optical properties. Thus, it is of great importance to identify factors that affect the morphology of nanoparticles formed in multicomponent solution with regard to kinetic phenomena in solution and on the NPs surface.

New principles of operating autooscillating processes in interphase of conductor-electrolyte by means of external permanent magnetic field are developed. Detailed description of autooscillating phenomena is obtained in interphase of conductor-electrolyte in permanent magnetic field. It is a new example of nonlinear self-organization in system that is dissimilar to thermodynamic equilibrium.

A set of methods for pipelined computer system synthesis is developed. The methods are based on mapping the spaced synchronous dataflow graphs (SSDFG) into the system structure and its schedule. The input data of the methods are initial SSDFG, given period of the algorithm implementation, and optimization criterium. The developed methods provide minimising the clock period as well as processor unit, register, multiplexor number, interprocessor communications, memory volume, energy consumption minimizations.

A number of approaches is developed for creation of monitoring information-analytical systems for scientific and educational activity support. The way of an efficiency estimation of using information-analytical, including monitoring information-analytical systems for solving problems of science and education on the basis of use spatial cognitive model of training is offered. Approaches to formation of  specialized information-analytical systems architecture are created.
