The development of energy-efficient technology of isostatic graphite production

Energy efficient technical solutions and regulations of pressing, baking and graphitizing of isostatic graphite artifacts were developed, which do not have any analogues in Ukraine and enable specific energy consumption decrease. Parameters of material base for isostatic graphite artifacts obtaining were determined and the requirements for “green” isostatic graphite samples, which are obtained on the pressing stage, were formulated.

Fundamental regularities in the synthesis of multifunctional water treatment reagents by chemical activation of alumina waste

A new theory of targeted activation of waste ("red muds") of alumina production has been created, and multifunctional water treatment reagents with a specified structure and clearly defined coagulation, sorption and biosorption properties have been obtained in the processes of removing inorganic and organic substances of various types and origin (heavy metals, dyes, active substances) from contaminated water.

Methods of evaluation and guarantee of technical security’s required level for specialized multiprocessor control systems’ functioning

Purpose of the work is design of methods and means for determination of transition’s probability of reconfigurable multiprocessor system (MS) aimed to control the complex objects. This transition can lead to dangerous state. Also as result of the work is enhance of system functioning results’ veracity. During exploitation due to the processors’ failures MS can went into dangerous state (that is state when is only one (any) of control functions can not be realized and without of those the control object went into dangerous state).

Investigation of the asymptotic properties of pseudo-regularly varying functions and generalized renewal processes

The aim of this research project was to study the asymptotic behavior of pseudo-regular functions and their analogues in stochastic analysis - generalized renewal processes, as well as applications of the results obtained to the theory of stochastic processes, statistics of stochastic processes, mathematical analysis and mathematical physics.

Formation of gradient states in nano layered metal film compositions via processes on the outer surface

Laws of energy induced diffusion phase-structural transformations in film functional-gradient materials with significantly different thermodynamic and crystal-chemical properties of the layers (V-Ag, Pd-Ho, Ni-Cu-Cr, etc.) were determined.
“Diffusion pump” effect was determined for investigated nanothickness materials: physical and chemical processes on outer surface thermodynamically determine diffusion phase formation in the bulk during energy impact in argon-, nitrogen-, oxygen-, hydrogen- containing atmospheres and in vacuum of 10-3 Pa, 10-7 Pa.

The processes of vapor generating in closed miniature evaporation-condensation systems with new coolants for space purposes

A complex study of heat transfer processes in constrained conditions in evaporative-condensation systems was carried out for the first time. A physical model of the boiling process on porous surfaces in conditions of limited space was developed and presented. Dependencies for calculating the heat transfer intensity under such conditions have been obtained. Such dependencies are necessary to create miniature cooling systems for microchips and powerful processors of electronic equipment.

Physico-chemical basis for strengthening of the light structural alloys surface by ultrasonic shock treatment at cryogenic temperatures

Essentially new scientific knowledge has been obtained on the physico-materials science basics and the laws of the surface layers hardening of the light structural alloys by ultrasonic shock treatment (UST) at cryogenic temperatures. These regularities are due to the suppression of the dynamic return processes and dynamic recrystallization, as well as the effect of the dislocations annihilation under the action of the deep cooling factor.

Unmanned aircraft and spacecraft thermal imaging systems

A new model of information transformations was developed for remote thermal imaging from an aircraft or space vehicle. This model takes into account characteristics of background, targets, the optical system and the matrix detector, which allows us to explore ways to improve the technical characteristics of the system’s main blocks. The computational algorithms are based on spatial-frequency filtering in the signal propagation paths and allow performing the tasks of analysis and synthesis of systems with or without visual perception. The model is compatible with the current NATO standards.
