Algorithm for individual learning content formation in automated machine learning system
The study describes the algorithms used in the formation of individual learning content which can be used in machine learning. The algorithm for generating educational content based on the input test procedure, thereby reducing the number of elementary units of knowledge in the educational conten
Dynamics of risk degree of innovation-driven growth at higher education institutions
In this article, the analysis of dynamics of risk degree of innovation-driven growth at higher education institutions is discussed. The survey has been employed in this paper and the data analyzed by SPSS software. Results revealed that the resulting risks are regularly encountered in a modern Russian higher educational institution: inability to provide necessary financial support for educational activities; inability to provide required modern material and technical basis; challenges and failures in collaboration with enterprises for organizing practical training for students and the absence of practical training programs at the university. It is also indicated that the risk event might lead to different results: negative, positive, or nul
Characterization of Ni-Cd Nanostructured System Obtained by Chemical Reduction of Salts
The process of obtaining of highly dispersed metal powders of Ni-Cd system by reduction of their salts by hydrazine in aqueous medium at high alkalinity was investigated. The possibility of production metal powders containing up to 50 mol% of cadmium is established and conditions for their synthesis are optimized. Phase composition, structural parameters, dispersity of solid products during the reduction
process were studied by X-ray diffraction (XRD) and SAXS. The formation of metal solid solutions with FCC lattice contradicts to the known phase diagram for Ni-Cd and may be explained by increasing the energy of the particles in the nanostate. The formation of intermetallide NiCd5 in the studied compositions area is caused by sequential character of reduction process; as a result the metal product on the initial stage of reduction is significantly enriched with cadmium
Kinetics of exciton photoluminescence in type-II semiconductor superlattices
The exciton decay rate at a rough interface in type-II semiconductor
superlattices is investigated. It is shown that the possibility of
recombination of indirect excitons at a plane interface essentially affects
kinetics of the exciton photoluminescence at a rough interface. This happens
because of strong correlation between the exciton recombination at the plane
interface and at the roughness. Expressions that relate the parameters of the
luminescence kinetics with statistical characteristics of the rough interface
are obtained. The mean height and length of roughnesses in GaAs/AlAs
superlattices are estimated from the experimental data.Comment: 3 PostScript figure
Darboux transformations, finite reduction groups and related Yang-Baxter maps
In this paper we construct Yang-Baxter (YB) maps using Darboux matrices which
are invariant under the action of finite reduction groups. We present
6-dimensional YB maps corresponding to Darboux transformations for the
Nonlinear Schr\"odinger (NLS) equation and the derivative Nonlinear
Schr\"odinger (DNLS) equation. These YB maps can be restricted to
dimensional YB maps on invariant leaves. The former are completely
integrable and they also have applications to a recent theory of maps
preserving functions with symmetries \cite{Allan-Pavlos}. We give a
dimensional YB-map corresponding to the Darboux transformation for a
deformation of the DNLS equation. We also consider vector generalisations of
the YB maps corresponding to the NLS and DNLS equation.Comment: 18 pages, revised version. The format of the paper has changed, we

The article analyzes the pace of the global steel market development over the past five years. The dynamics of Β«Metinvest Holding LLCΒ» Ukrainian companies for the same period of time. The basic tendencies of development of the global steel industry. The analysis of basic production and economic performance of Β«Metinvest Holding LLCΒ»y. The dynamics of economic indicators: the level revenues, EBITDA, net profit, the value of the company's assets. The dynamics of production indicators: steel production, the volume of iron ore and coal mining. The main reason for the decline and loss of efficiency of the company is to reduce the volume of production of the main products of the company: steel, iron ore and coal. Using the author's methods to assess the level of efficiency of management of competitiveness of the company. Based on the analysis of basic production and economic indicators and the results of the calculation of the efficiency factor of competitiveness management concluded that reducing the efficiency of management of competitiveness of the company Β«Metinvest Holding LLCΒ». Using calculations proved that the largest decline recorded in the evaluation of the effectiveness of resource management competitiveness. Guide companies need to pay attention to the efficient use of all resources. Important reserve for increasing the efficiency of management of competitiveness is the use of administrative synergies that arise in the management of large corporate structures
Bose--Einstein solitons in highly asymmetric traps
We obtain analytic solutions to the Gross-Pitaevskii equation with negative
scattering length in highly asymmetric traps. We find that in these traps the
Bose--Einstein condensates behave like quasiparticles and do not expand when
the trapping in one direction is eliminated. The results can be applicable to
the control of the motion of Bose--Einstein condensates.Comment: 12 pages, Latex, Figures available under request on

Globular Clusters as Candidates for Gravitational Lenses to Explain Quasar-Galaxy Associations
We argue that globular clusters (GCs) are good candidates for gravitational
lenses in explaining quasar-galaxy associations. The catalog of associations
(Bukhmastova 2001) compiled from the LEDA catalog of galaxies (Paturel 1997)
and from the catalog of quasars (Veron-Cetty and Veron 1998) is used. Based on
the new catalog containing 8382 pairs, we show that one might expect an
increased number of GCs around irregular galaxies of types 9 and 10 from the
hypothesis that distant compact sources are gravitationally lensed by GCs in
the halos of foreground galaxies. The King model is used to determine the
central surface densities of 135 GCs in the Milky Way. The distribution of GCs
in central surface density was found to be lognormal.Comment: 22 pages, 4 figure
Extended parametric resonances in nonlinear Schrodinger systems
We study an example of exact parametric resonance in a extended system ruled
by nonlinear partial differential equations of nonlinear Schr\"odinger type. It
is also conjectured how related models not exactly solvable should behave in
the same way. The results have applicability in recent experiments in
Bose-Einstein condensation and to classical problems in Nonlinear Optics.Comment: 1 figur
