Specialized Computer System for Diagnosting and Reliability Calculation of Reconfigurable Fault-tolerant Multiprocessor Systems

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.

The creation of cast barriered shell for bimetalle and combined hydrogen-storage balloons

Analysis shows modern design balloons from austenitic steels, which they characterizes lack resistance to corrosion in a hydrogen environment. This leads to a «hydrogen degradation» of the vessel wall and loss of hydrogen in environment deference. There exists an technology of manufacturing the protective barrier membranes by coating the inner wall of the silver gold and copper, stainless steel, can prevent the penetration of hydrogen through the walls of the cylinders and to ensure reliability during their operation.

Development of mathematical models of choice of the optimum modes and perspective development of system connections of grids of Ukraine

The working out essence consists in creation of the specific mathematical apparatus intended for the decision of problems of optimization of operating conditions of a backbone network of the main ExtraHVAC transmission lines taking into account uniform distribution of parameters along length of such lines and estimation of features of wave processes by transfer on them of electric energy.

Development of theory of designing for machine tools of new composition on basis of system’s analysis and synthesis of mechanisms with parallel structure

Conception of planning and arrangements of machine-tools of new generation is offered, the basic features of which followings:

-  The genetic going is near classification, description, evolution of development and prognostication of machine-tools as to the difficult technical systems of prirodno-antropogenogo origin.

-  The multilevel morphological going is near a construction and synthesis of the difficult technical systems.

-  Application of framework thecal constructions of the bearings systems.

-  Aggregate-module principle of arrangements.

Development and investigation of perspective miniature energy saving devices on based of evaporating - condensation cycle.

Analysis of literature sources had shown that up-to-date state of miniaturization of electronic devices needs the development of new small-size cooling systems, which are capable to reject great heat fluxes. Within the bounds of this problem theoretical ground of advisability of using miniature heat pipes, thermosyphones and oscillating heat pipes in cooling systems for a wide range of powerful elements of microelectronic technics was found.

Investigation of the processes and development of high efficiency resource-saving ecological-safety technology of deep arsenic removal from water

The information about both, natural and anthropogenic ways and the reasons of arsenic compounds appearance in natural waters are generalised. Prevailing forms of the presence of arsenic compounds in water medium are defined. The comparative analysis and summarization of the existing information on the novel methods and materials for deep extraction of arsenic from water are carried out.

Scientific and technological government a structure and properties of castings multicomponent alloys of the system of Al-Mg bases.

On the basis of undertaken analytical and experimental studies intercommunication is set between chemical, phase and structural composition, technological parameters of treatment and level of properties of casting multicomponent alloys of the system Al - Mg.

Highselective resonant-tunneeling crystal-like signal processing devices.

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.

Nanosized metal oxides: synthesis, structure, physico-chemical and electrochemical properties, applications.

It is known that substances with crystal size less than 100 nm possess some valuable properties which are not known for the substances in bulk or macrocrystal state. In particular, nanosized metal oxides become electrochemically active, which permit to use them in energy storage systems.

The conditions for the reactions of oxidation of metals (titanium, tin, tantalum) and their compounds were determined for the synthesis of the nanosized oxides.
