The research of the water dispersion parameters in impact with a hard dry and wetted surface was made. Noted best water spraying at surface with high roughness. This may be due to the difficulty of the air outlet from under flat (before impact) drops during impact. The share of dispersed liquid upon impact a teardrop-shaped expanding jet ( 40% of the water flow in the jet ) with wooden batten was investigated. Also was determined the radius of scattering droplets depending on the fall height and of the water flow consumption from the nozzle.

The functional and biocompatible composition coverages formation on Ti- and Fe-alloys, with hardened by carbon nanotubes and intrusion elements, at the terms of extreme power influences

For the first time the scientific basis of a fundamentally new method of forming biocompatible (titanium alloy) coating of carbon nanotubes (CNT) in polycrystalline silicon oxide layers with nickel and iron catalytic centers are obtained by CVD for implants, dentures support-the driving apparatus of human and medical instruments were developed. For the first time a model of physical and chemical processes of the composite coatings formation under laser irradiation of CNT substrates with pre-coated with a layer of hydroxyapatite powder were proposed.

Thermal stability and operating reliability of nanosized metal films on insulators and semi-conductors

Термічна стабільність та експлуатаційна надійність нанорозмірних металевих плівок на діелектриках та напівпровідниках

A comprehensive scientific approach to account for the "cross-effects" influence of physical and thermal deposition process parameters on structure and properties of nanoscale metal films Cu-Sn, Cu-Au, Cu-Mn, Cu-Sn-Mn, Al-Mn-Cr, Ni- Al, Ni-Au, Ti-Ag, Fe-Pt, and etc has been developed. The general regularities of diffusion processes due to subsequent thermal annealing in ultra-high vacuum, oxygen- and hydrogen containing atmosphere, ion-plasma and laser treatment have been discovered.

Technology of combined energy-efficient power stations with integrated use of distribution generation and smart-technologies

The methodology and mathematical tools for solving problems of the integrated energy systems development is created. Proposed methodology is based on combined use of distributed micro power stations with distributed generation, with taking into consideration the existing energy infrastructure of the region, resource base, the potential of renewable energy, environmental constraints, economic and social risks.

Research of ultra wideband impulse radio signals properties and development of self-organizing radio networks based on these signals and terminals for them.

Макети радіотерміналів, які можуть бути об’єднані в радіомережу із самоорганізацією

A new theoretical base and new methods of using ultra wide band radio signals in self-organized radio networks were created. The main idea of the self-organized networks is based on a fact that each terminal in the network acts not only as final transmitter and receiver of information but as a repeater – router for all subscribers in the network. Each terminal provides network parameters evaluation and optimizes information traffic control mechanisms.

Research and theoretical studies of new precision inertial navigation system in extreme conditions using neural networks

The actuality of solving the problem of fundamental researches of a new precision inertial navigation system (NS) in extreme conditions, which is the important constituent of the aviation gravimetrical system, is grounded. The classification of NS is resulted. The system of NS controlling has been improved.

Dynamic analysis of threats priorities economic dimension of sustainable development administrative - territorial units of Ukraine

Dynamic model of the economic dimension in view of the threats identified and its characteristics for the local government area. The method of calculating the level of threat, which includes grouping sets of data for specific classification features that characterize a particular threat , to create a database for a certain period, the definition of inter depending on the components and the maximum level of threat, the calculation and analysis of the formation of recommendations. The dependence of the functions described and graphically represented in the work.

Increasing of the efficiency and serviceability of equipment of power plants and small engineering during variable mode of operation

The recommendation for designing of air dust-feeders, which ensurance uniform feed of dust to burners of the boilers when low-reaction coal is burnt in working conditions of 300 MW energy unit are worked out. The plan of the branch standard “The method directives for developing, designing and putting in practice of the system of dust feeding with high concentration (under the pressure) to boiler 300MW energy units, which burn low reaction coal” are prepared.

Bezklinkernye inorganic binders with care tonnage thermal power plants - ash and wall products based on them

The purpose of the research is to develop a inorganic binders based on tonnage waste thermal power plants and wall building products based on them.

In carrying out the work were identified pozzolan and hydraulic activity of ash of thermal power plants, depending on the temperature conditions of synthesis and chemical characteristics of the system. Find supplements activators that can adjust the speed of the processes of structure formation.
