Fundamental research

A new concept of architectural and algorithmic organization of software that supports information learning environment was worked out. The concept describes a number of modules such as monitoring and processing of the heterogeneous educational information resources module, module for indexing for all types of search (attributive, fulltext, quasisemantic, associative etc), modules which provides intellecualized possibilities such as referencing, clasterization, classification. A new method of organizing data to support the entire range of search possibilities was created.

Was developed a new concept of composing and development of large-scale information management systems and open public media, a number of mathematical models and methods of analysis, design, implementation and operation of control systems of cloud IT infrastructure that automates critical cloud computing processes that allow you to create technology-aided design and management of cloud IT infrastructure.

The overall fundamental problem to be solved by the project is the development of mathematical models and methods of hierarchical planning and decision making in a complex organizational and production systems with network representation of technological processes and limited resources.

Methods for morphology control in a process of nanostructures growth by deposition of atoms diffusing from solution to the forming surface are developed. Surface restructuring is considered, yielding morphologies of interest in catalysis. Shape selection for nanoparticles and surface nanostructures occurs in appropriate "nonequilibrium" regime of properly balanced rates of various processes.

Created new science concept, new methods of analysis and control in the field of security of complex systems. Constructed new logical-probabilistic models allows to formalize the description of complex systems security problems and ensure a unified methodological framework for its solution. Created new scientific approaches for constructing a new class of complex information security systems.

The object of research is the directed crystallization partly of semitransparent materials from melt. The subject of research is mathematical models of radiation-conductive and radiation-convective heat exchange. Mathematical models and techniques of numeral solution of tasks of ra-diation-convective heat exchange are worked out taking into account influence of impurities in melt on an asorptance and selectivity of optical properties of semitransparent crystal and melt.

The new enthalpy-entropy method of the thermodynamic analysis of gas turbine cycles and combined on their basis energetic installations is developed. Methods of the thermodynamic forcing, at the first, of basic gas turbine installations by connection to them of closed gas turbines, which produce additional electric energy by utilization of the gas turbine exhaust gases heat potential, and, at the second, one-fuel monic gas-steam installations with using of the steam extended expansion turbines is proposed.

It is developed new approach for diffusion formation of stable nanoscaled magnetic-hard FePt films with chemically ordered L10(FePt)FCT phase at using additional layers of alloying elements (Ag, Au, Cu) with low surface energy. The energy of interface between layers was applied as additional superior-driving force for acceleration of thermally activated processes of chemical ordering FePt film and decreasing of temperature (~ 100oC) of phase transformation of chemically disordered magnetic-soft А1(FePt)FCC to chemically ordered magnetic-hard L10(FePt)FCT phase with superstructure.

Electro-magnetic waves propagation in atmosphere is of great theoretical and practical interest because using laser radiation for information transmission through the earth's atmosphere has many obvious advantages over traditional communication methods. However, fluctuations of the refractive index in the atmosphere, caused by turbulence, lead to the optical field fragmentation in the detecting area and to the beam wondering in regards to the initial direction.

New complex mathematical model of heat transfer processes in conditions of evaporation-condensation systems (miniature heat pipes, thermosyphons and pulsating heat pipes) inner space decreasing was developed. Criterial relation for evaluation of miniature heat pipes heat transfer ability was obtained as a result of differential equations system and conditions of uniqueness analysis.
