Expansion of the fuel base and improvement of environmental indicators of stationary and self-propelled systems with diesel engines through the use of gas diesel cycle

A universal gas diesel fuel supply system with microprocessor control (MPSS) for the conversion of diesels of stationary and transport facilities of average power, including military engines, to work on the gas-diesel cycle, which allows to improve the energy and environmental performance of the engine, reduce the consumption of diesel engines more expensive diesel fuel and attract cheap fuel for environmentally friendly gas to the fuel fund.

The increasing of efficiency and economy of the operation of the energetic equipment under different kinds of fuel and conditions of the load control

The experimental curves of the creep and the long-term strength of 25Kh1M1FA steel have been scientifically substantiated and proved by studying of the rotor of power unit No. 9 on the Luganskaya TES which had worked 275 thousand hours and reproduced all aging processes for the entire period of operation. The experimental curve of the long-term strength is supplemented taking into account the creep, which was limited a range of 175 thousands hours, up to 375 thousands hours.

Distributed systems for collecting experimental data on the basis of virtual IP-modules

A set of hardware and software for constructing distributed multi-channel microcontroller acquisition systems and processing of measurement information based on virtual measuring network networks supporting IP protocol, common digital interfaces, specialized CoAP/CoRE network protocols and flexible software configuration of measuring channels in a multitask environment is developed. An approach is proposed to construct systems for collecting and processing experimental data as a multilevel network of virtual measuring modules.

Development of the information-analytical foresight system for social disasters caused by catastrophes and terrorism

An information-analytical foresight system was developed for the problem of social disasters. This system is based on using scenario analysis methodology for timely detection of reasons, modeling, study and mitigation of consequences of social disasters, caused by different reasons, particularly catastrophes and terrorism.

Development and research of aluminum heat pipes with threaded capillary structure for cooling LED lighting devices.

For lighting in the world, 19 to 22% of the generated electricity is consumed. The introduction of energy-saving technologies in lighting systems will provide significant energy savings and improve the environmental state by reducing emissions of thermal power plants in the environment. One way to save energy in lighting is to switch to LED lighting. Light output of LED light sources is 10 times higher than the light output of incandescent lamps and 2 times - compact fluorescent lamps containing mercury.

Heterogeneous telecommunication systems based on the stratospheric platform using modern telecommunication technologies and hardware

The main obtained results are the development of scientific and technical principles for the creation of heterogeneous telecommunications systems of the next generation with high throughput, the nodes of which are located on the platform of the stratospheric unmanned aerial vehicle, which enables such a system to integrate into existing local communications, which are located in the coverage area of the aircraft.

Portable system for automatic object tracking in video sequences

The portable system of automatic visual object tracking in a sequence of images of increased reliability and speed has been developed. The system finds the trajectory of a given object in video sequences determining its coordinates on each frame. The improvement of the system performance is achieved by developing and modifying tracking techniques as well as the structural and functional organization of the embedded software and hardware aids of their implementation on the ARM Cortex-A processor core.

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.
