Information and communication technologies

The methods for implementation the group operations for finite groups of arbitrary order and operations in finite fields with given characteristic in linear logic networks, which implementation oriented on programmable logic integrated circuits (FPGAs) are proposed and investigated. A list and the basic properties of group operations for groups of order 2n, which are implemented by regular logic networks of linear complexity for all values of n are defined.

The new technology of deposition of nanoscale (20-50 nm) ferroelectric films (NFF) for the non-volatile memory elements (ME), including the method of RF magnetron sputtering with closed drift of high-energy secondary electrons. Processed using the method and means of RF sputtering plazma monolithic ceramic targets based compounds zirconium, titanium, lead in the direction of reducing the thickness of the film, the technology of ultrasound treatment NFF, which provides an increase in the polarization reorientation and reduction of stress reversal.

The information platform of scenario analysis in the form of the mathematical and software support of the decision of  foresight problems of identification promising directions of development at the level of large enterprises, industries and regions is developed.

The program complex of calculation of reliability of non-failure operation of reconfiguring Fault-Tolerant Mulltiprocessing Systems (FTMS) by means of statistical experiment with the GL-models reflecting behavior of FTMS in a stream of refusals of their components is developed. The new mathematical grafo-logical models (GL-models) adequately reflecting reaction of FTMS to occurrence of refusals optimized for use in specialized system are offered.

Nanoelectronic signal processing devices based on crystal-like structures are the newest element base of information and telecommunication systems. Resonant-tunneling crystal-like structures and devices based on them with very high spectral selectivity are proposed. High-performance microwave microstrip signal processing devices are developed. To improve the efficiency crystal-like structures used in the modes conventional tunneling - resonant tunneling. Together, these effects provide maximum decoupling of signals in the passband and stopband.

Experimtntal studies of information-measuring system showed prospects for use such  devices for  vehicle security system  and the  measurement of  stress-deforming state of railway locomotives. Combining them into a single complex with a satellite navigation systtmand a digital maps aliow to accurately determine the position of the car on the road. 

The aim of work are creation and introduction of hardwarily-programmatic complex with the increased exactness of echolocation  of fuel in the tanks of trucks and level of underwaters through pipe waveguides with the use of normal waves.

As a research method is used computer design of echolocation in waveguides on normal waves, experimental design on the laboratory model of complex.

The principles of construction, modeling and design, design methodology in the range of

5...100 GHz telecommunication devices (TAP) and their components (filters, amplifiers, etc.) and hardware components (lines, transitions, etc.) through the use of metamaterials and integral multi-layer LTCC technologyand, LCP, and examples of implementation of thedevices on that basis.

Models, methods and software complex for optimization of investment  portfolio in condition of uncertainty were created

The development of modern technologies in the field of electronics and the complexity of the devices being designed leads not only to an increase in time spent on the solution, but also increases the probability of the analysis procedures failure due to the accumulation of instrumental and methodological errors. At the present stage of microminiaturization, more physical effects should be taken into account complicating significantly the process of the objects’ dynamic analysis.
