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.

Thermomolecular accumulator with the new working medium based on heteregenious liophobic system.

The new results were obtained on the principles of thermomolecular energetics (TME) as a new theory of the use of potential energy of intermolecular interaction on developed surfaces in applied applications of accumulators with high specific (volumetric) energy capacity, with less consumption of structural materials. Three samples of the new type of accumulator with a high specific energy capacity have been created, which work on the principles of thermomolecular energetics using heterogeneous lyophobic systems as a new working media.

Improving energy and resource efficiencies parameters on basis power electronics for highly reliable technology for welded joints of heterogeneous materials

The object of research work is electromagnetic processes in the system "power grid - power converter - non-stationary load". The aim of the work is to increase energy efficiency and resource saving by means of power electronics for the technology of obtaining highly reliable welding joints of heterogeneous materials.

Anthropomorphic robotic ransport device for human unloading in conditions of high risk and uncertainty of terrain

A new analytical model of ARTD kinematics, model of the dynamic behavior of the walking apparatus when moving on an arbitrary surface, has been developed a structural diagram, has been synthesized for the interaction of the robotic transport device systems with its nodes. Created computer models of kinematics and dynamic behavior work, shows the interaction of the executive bodies of the ARTD with its sensory system through the environment.

Theoretical and experimental investigations of electronic, magnetic and optical properties of nanosized carbon-containing materials

Luminophores of “white light” are an important part of white-light-emitting diodes, and the main part of these diodes consists from UV light sources (usually an InGaN based light-emitting structure) and a luminophor transforming UV into a broad spectrum of white light. To date, rare earth or heavy metals are the main components of luminophors leading to its recycling complexity and increase in manufacturing costs. Moreover, the spectral characteristics of the modern commercial luminophors do not correspond to the spectral characteristics of the sunlight.

Creation of methods for designing the processes of shaping engineering structures under viscoplastic deformation of homogeneous, eutectic strengthened and powder materials

In this work, using a unified theoretical approach, the analysis of the processes of visco-plastic forming of typical mechanical engineering structures with homogeneous and structurally heterogeneous materials. The theoretical approach is based on a closed system of equations of the theory of plastic flow of continuum mechanics, taking into account the visco-plastic properties of materials. This approach made it possible to provide system design of structural forming processes.
