Information and communication technologies

The main scientific results are the services processing technology with the integration of information resources in the request service systems, that will allow significantly increasing the efficiency of technical resources in the provision of services to communication subscribers, allow for distributed processing of requests for user services and their billing, allow improving the quality of customer service and increasing the intelligence of service process.

The vision system for the high dynamic range (HDR) video signals is developed. The system performs the HDR image compression to the signal with dynamic range of 48 dB without loss of sharpness in the light and dark areas and no artifacts, and has moderate hardware costs when it is implemented in FPGA. The Retinex compression algorithm based on the bilateral function is considered. A simplified HDR compression algorithm is proposed, that uses the intelligent image analysis of local characteristics instead of the bilateral function .

The results of research led to the creation of new types of standardized devices for interference-free data transmission in high-speed channels, microwave and satellite communication, which are the main technical and economic parameters exceed the available foreign analogues.
Unification is implemented as a range of frequencies used for (2 GHz, 5 GHz, 12 GHz, 130 GHz) and by type of radio channel (microwave and satellite).

It is proposed a theoretical and methodological basis for creating wireless sensor networks (WSN) monitoring of environmental parameters. Synthesized new WSN topology control algorithms. Formulated approaches to building the knowledge base (rules) to control the topology of WSN. An improved method of energy-efficient data aggregation in WSN, which uses a new way to reduce the energy use of individual nodes WSN by limiting their number for message transfer over the period of data collection.

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.
