Developing effective methods of maintaining soil fertility in accordance with the paradigm of sustainable development.

Conducted theoretical experimental researches of forming process a lot of puffs crystalline amorphous nano- the structures formed by mass crystallization in the presence mykro- and makro- admixtures on the surface of dispersion phase in the dynamic dispersions systems.

Terms are certain formings and mechanism of formation of organic mineral hard compositions matters with a layer structure from the homogeneous and geterogeneous liquid systems.

Investigation of the system of high concentration fuel supply under the pressure for highreaction fuels and energysaving gas burners for boilers.

The analysis of results of works, which were carried out on the problem of oxidation and self-ignition of coal for improving accuracy of the program of investigation of coal self-ignition, was carried out.

Creation of scientific and technological foundations for the development of advanced high-performance heat transfer surfaces.

The design of flat-oval profile steel tubes with the incomplete fins is investigated for use as heat transfer surfaces. Such surfaces have several important advantages: the material - carbon steel, manufacture of low-cost technology – contact welding of the fins on the tube; improved thermal efficiency as compared with steel tubes of round profile, aerodynamic drag of flat-oval tubes with incomplete fins for 40...50 % below the tube of round profile.

Fundamentals of adaptive electromechanical control systems based on vector-controlled AC motors under incomplete information.

The theory of stability of multivariable nonlinear systems is extended allowing development of new design methods of control. The methods provide decomposition of the original system into the interconnected subsystems with the structural properties ensuring the local exponential stability of the composite system and quasi-independence of the subsystems’ processes along with the asymptotic linearization of one of them.

Electronic processes in the breakdown electric fields in the polytypes of silicon carbide

Conditions for creation of light emitting diodes working in electrical breakdown regime have been determined. The floatable technology have been used. Light emitting diodes obtained is possible to use as standards of power and spectral composition of radiation, and although for creation of sources of short light impulses. Constructions of these devices, laboratorial technology of their fabrication, elements of metrological support have been worked out.
Emitters on SiC-basis operating in the electrical breakdown regime have the following superior characteristics:

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.
