Intractable problems of combinatorial optimization and the theory of PSC-algorithms

The work continues a series of works devoted to the development of the theory of PSC-algorithms and to the creation on its basis of models and methods of scheduling, operational planning, and decision-making in complex socio-economic systems with a network representation of technological processes and limited resources.

Physicochemical bases of low-temperature synthesis (700 - 1500 оС) of ultra-refractory high-strength reinforced ceramics and metal-ceramics of multifunctional application

An integrated approach to the creation of scientific physicochemical foundations of the process of synthesis of large polycrystalline samples or products of reinforced ceramic high-temperature materials at low temperatures is implemented, which involves the use of a capillary-porous body with predetermined structural-geometric characteristics of pore channels as a medium for growing fibers reinforcement (the first at the level of separately taken powder particles from which a capillary-porous t is made) ceramic composite.

Creation of technologies of plastic deformation of homogeneous and powder materials in conditions of superplasticity for maintenance of a resource and reliability of the high technology products

Design and technological classification of standard blades of modern gas turbine engines is developed. Selected typical elements of solid and hollow blades for which tasks are set for the development of manufacturing technologies.

Tools of asymmetric response to hybrid aggression in the humanitarian field

The problem of the scientific work is the absence of asymmetric response tools to the threats of the hybrid warfare in the areas of possible aggressive manifestations: in literature, media, cinema, history, psychology, public administration, diplomacy, relations with the diaspora. The absence of the established mechanisms and means of information confrontation threatens national security, territorial integrity, economic prosperity and sustainable development of the state.

Creating and characteristics research of university CubeSat format nano-satellites for remote observation of the Earth

The work is devoted to the creation of a nanosatellite (CdS) format Cubesat, 3U by developing, modeling and researching efficient service subsystems to provide a payload - an opto- electronic scanner with a capability of shooting in the range of up to 30 m when it operates in orbit at altitudes up to 700 km.
The above works are carried out by the students of the undergraduate, postgraduate students and research staff of the following faculties: TEF, PTF, FEL, FAA, PBF and MMI, as well as attract specialists of PJSC "Pivdenne" (Dnipropetrovsk) as consultants.

The complex of devices for monitoring and diagnostics of gas analytical systems for the determination of cyanide conduit.

The potential range of electrochemical stability of titanium and catalytically active electrodes based on it in solutions of sulfuric and perchloric acid is determined. It was established that the production of hydrogen cyanide in the process of anodic oxidation of thiocyanate with a current efficiency of HCN of about 100% is possible using a 1 M KSCN solution.

Using of the potential of hydrobionts for the conversion of biosources and wastewater pollution

A new technology of processing of bioremediation with obtaining energy carriers while simultaneously clearing sewage from fish farms with a closed cycle of water supply has been developed. A closed cycle of waste processing has been created, in which at each stage the necessary association of microorganisms is selected. The purification of sewage from biogenic elements is proposed with the help of microalgae, the metabolism of which is guided by change for the purpose of increased release of triacylglycerols (raw materials for biodiesel fuel production).

Development of efficient electrobus electromechanical system based on adaptive vector- controlled induction motor drive with accumulator-ultracapacitor power source

An experimental electrical drive for electric buses and traks is developed and experimentally tested. Developed power converter for induction motor based electrical drive provides 100 kW of output power. Flux-torque (speed) control algorithms for induction motor are developed, implemented and experimentally verified. Developed nonlinear controller take into consideration motor's magnetizing curve provides asymptotic flux-torque (speed) tracking, torque per Ampere maximization (MTA) as well adaptation to stator and rotor resistances.

Management of municipal facilities energy consumption

The main structural schemes of interrelations between the subjects of the thermal energy market are determined and the corresponding models of the thermal energy market are proposed depending on the localization level of the heat supply system. Effectiveness of the system was analyzed for two alternatives: monopoly and competition. Modeling the interaction of market participants was done using different technologies for the production of heat energy, in a competitive environment.
