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.
The method of system engineering of business-models of organizational systems from the financial-investment activity, based on methodology of the system analysis and system engineering which, unlike available methods, considers features of organizational system due to use of business-structure (formalizes essence of organizational system), ontology (formalizes a sphere of activity of organizational system) and process of business-modelling (regulates creation of business-models) is developed.
A model of integrated quantitative evaluation of sustainable development of the municipality is created using the procedure of building a system of indicators in accordance with the program-oriented approach, including the coordination of data and methods of constructing composite indicators, methods for identifying critical indicators, etc. To work with the model’s data information subsystem for collecting, processing and storage of data is developed.
A set of hardware and software for building networked microcontroller systems for the collection and processing of experimental data on the basis of the network of intelligent sensors to the IEEE-1451 with the support of specialized Web-protocols and built-in Java-related technologies. This data collection system is constructed in the form of Ethernet-network of intelligent sensors with providing Internet-based access protocol MQTT and Java-related technologies.
A methodological and methodical toolkit of information-expert foresight system for processing unstructured information was developed, which includes the development of approaches to the analysis of unstructured data for the foresight platform and development of methods for determining the semantic coloring for pieces of unstructured information.
Gas-dynamic and heat transfer mathematical model of supersonic flow over flying vehicles is developed. The model is taken into account with medium compressibility and dissipative effects leading to an increase of heating rate. Proposed model is based on physical interaction of shock wave and boundary layer. Three dimensional numerical models of flying vehicles in gas-dynamic states are developed in order to investigate different configurations concerning such systems as case - sharp swept fin, case - perpendicular cylinder, case - gas jet, case - sharp unswept fin.
Integrated optimization of production technology of radiation-resistant solar cells based on the A3B5 heterojunctions, on the single-crystal silicon as well as on the nanocrystalline silicon films doped with rare earth elements formed by the method of synthesis of nanocrystalline silicon thin-film layers. Technological operations for manufacturing of high-performance radiation-resistant nanocrystalline silicon thin film solar cells and the A3B5 heterojunction solar cells have been developed and practically realized.
