The theory was developed of propagation of spin waves in two-sublattice antiferromagnet with uniaxial magnetic anisotropy and ferromagnetic nano-shaped spherical nanoshell, nanoshell of an ellipsoid of rotation form ("nanorise"), cylindrical nanotubes of circular (circular cylinder) and elliptical (elliptical cylinder) section and for arbitrary ferromagnetic nanosystems with transmitting symmetry.

Conditions for creation of light emitting diodes working in electrical breakdown regime have been determined. The floatable technology have been used. Light emitting diodes obtained is possible to use as standards of power and spectral composition of radiation, and although for creation of sources of short light impulses. Constructions of these devices, laboratorial technology of their fabrication, elements of metrological support have been worked out.
Emitters on SiC-basis operating in the electrical breakdown regime have the following superior characteristics:

A new architectural concept of parallel computing in GRID systems and cloud environment is proposed, which uses FPGA as a high-performance heterogeneous computing resource. FPGA is used as heterogeneous programmable operating unit for processing data streams, allowing for achievement of optimized performance-related energy consumption. The concept simplifies programming the computational problems for these systems.

Spectral, thermal and electronic properties of a new class of hydrocarbon-based materials diamondoid oligomers was investigated. The methods for the selective functionalization of lower and higher diamondoids were developed. Methods of association lower diamondoids in lower oligomers have been developed. X-ray diffraction and thermogravimetric spectra of lower diamondoid oligomers were made. We propose a model that adequately accounts the effects of dispersion interactions in diamondoid oligomers for their physicochemical characteristics.

A number of approaches and methods was developed for creating of global electronic space monitoring program means. The means allow to quickly actualize professional electronic scientific and educational resources.

The aim of the project was a further development of the theory of pseudo-regular and special functions and their applications to limit theorems of renewal theory, study of asymptotic behaviour of solutions to stochastic and deterministic differential equations, investigation of linear and non-linear models in stochastic analysis, statistics of stochastic processes with long-term and short-term dependence, integral equations and transforms.
In the project:

On the base of the results determined by using modern physical material science methods scientific principles referred to relationships for combined effect of sever plastic deformation and temperature on diffusive processes, phase transformation, evolution of structure and thermal stability of mechanical properties of nanostructured composite Al alloys reinforced by ultra fine particles of metastable quasicrystalline phases has been developed for the first time.

New conception of building of industrial multi-level autonomous invertors on the base of spectral orthogonal transforms of discrete functions with m-ary argument and m-ary counting system. Means and devices to compensate reactive load power for autonomous multi-level invertors are developed. Method for building of energy-supply systems on the base of multi-level invertors and parallel filter-compensating devices is proposed. Structure of power part and control system of three-phase autonomous invertors and system for providing of assigned value of non-symmetry factor are developed.

The new link adaptation method was created based on multicriteria channel state estimates with fuzzy logic mathematical apparatus. Matching link adaptation algorithms were created with usage of unusual improved fuzzy inference algorithm based on both link state energy estimations and multicriteria estimations (energetical, probabilistical, and statistical). The rules of membership function construction were determined. They are constructed by direct methods based on simulation results or laboratory measurements of stationary channel immunity.

A new fundamental scientific concept of purposeful synthesis of metal oxides and nanocomposites «metal oxide/multiwalled carbon nanotubes» structure with controlled and predetermined properties, which may be used as photocatalysts and electrocatalysts, energy conversion devices is created. Conceptual bases of alternative methods (high-temperature electrochemical synthesis and recovery metallothermal) direct synthesis of nanostructured silicides metals VI-B group are proposed.
