There were created new computational methods of objective assessment of the spatial and energy resolution of space-based infrared cameras on the basis of physical and mathematical model of electro-optical system for forming and converting signals from terrestrial objects and backgrounds to the final information package of thermal imaging system.

The techniques of complex assessment of resource efficiency, impact on environment and safety of different scale objects and systems are developed for effective decision making and management. Indicators for environmental component assessment of sustainable development of the regions of Ukraine and their vulnerability to environmental threats are proposed including resource efficiency and carbon intensity criteria. Complex analysis of environmental component is carried out in sustainable development dimensions for regions and macroregions of Ukraine.

The comparative tests of multi-stage centrifugal distillers are conducted with two types of heat-pumps – mechanical steam compressor and thermo-electric heat-pump, advantages and lacks of their use are certain in the systems of life-support for space aircrafts with a crew onboard. Developed and executed measures on modernization of construction and separate elements of centrifugal distiller and thermo-electric heat-pump, that allowed to promote efficiency of their work.

Object of research is the educational nanosatellite (further NS) a format 2U CubeSat.
Objects of research are a subsystem of navigation for NS on an earth orbit with receiver GPS/GLONASS, a subsystem of orientation of NS, a subsystem of communication of NS to ground station with a format of data interchange AX.25 and BPSK modulation.
The operation purpose is development of subsystems of navigation, orientation and communication of NS by methods of physical modeling and an experimental research of the main parameters of subsystems.

Continuous growth in cooling water shortages and increase of environmental requirements through thermal pollution is closely linked with the problem of rational use of water resources and reducing water-intensive technologies. This necessitates the usage of modern energy technologies and their upgrading with help of existing cooling systems in a variety of industries.

Electric circuit diagrams and technical solutions, which improve technology formation of low-frequency ultrahigh voltages (up to 500 kV) for certified tests of power cables with modern po-lymeric insulation on voltages to 330 kV are developed.
Circuit diagrams and solutions are based on practical realization of a power series resonant contour with adjustable precision Q-factor (Q ≈ 40) in the test installation that provides formation of resonant test voltages with instability ≤ 1 %.

Up to 30% of the produced electricity is being spent on the lighting in Ukraine. Therefore, the problem of energy saving in lighting stands very seriously. Introduction of energy-saving technologies in the internal lighting systems will provide significant energy savings and improve the ecological condition by reducing atmospheric discharges of thermal power plants.

The technological and economic analysis of existing and long-rang power generation technologies is maid. The performance testing and production costs for modernized and advanced units are determined. The criteria optimizations, necessary technological, economic and regime restrictions and balance values were find.

Intensification of the process of dispersing the liquid through the use of hot water made it possible to develop a new technology for the fine spray of water without using high initial pressure, which greatly simplify the system of water supply to the flow of cyclic air in order to implement a highly efficient process of evaporative cooling cyclic air GTE. The use of superheated water implements explosive boiling of the water jet exiting the nozzle, allowing to achieve the necessary quality of atomization without the use of high pressure nozzles and complicated construction.

There is developed a methodical-algorithmic toolkit for the system modeling of the landslide-prone slopes stress state, implementing the new concept and strategy in solving the inverse problem of a sustainable location for the buildings and the constructions in the landslide sites in conditions of destabilizing soil masses degradation factors.
