NEW SCIENTOMETRIC INDICATORS RESISTANT TO ARTIFICIAL “IMPROVEMENT”
DescriptionThe article presents the new criteria suitable for the diagnosis of the productivity of research and the importance of its results for the scientific community, are resistant to artificially "improve". It is known that generally accepted measure of the productivity of research scientists is the h-index, which is calculated based on a statistical method of scree. This indicator is applicable to research teams (organizations). However, the h-index and a number of other scientometric indicators based on citation, are easy to be artificially increased (fraudulent schemes action). New scientometric parameters adequately reflecting the importance of research results, and not amenable (or very difficult to) to be artificially "improved" are therefore needed; moreover, it is recognized around the world: the true score (not fictitious) of the significance of the results of a research scientist for the scientific community - is a complex metrological (scientometric) task. The authors argued that such indicators are primarily index latitude demand for research results, as well as a number of other parameters of copyright. Despite the fact that authors indicators, the same as the h-index are based on citation, their large values indicate that the scientific community recognizes the results of the research activities of scientific and pedagogical workers; moreover, these indicators can be considered as a criterion to identify really promising (productive) researchers. The problem of adequate assessment of the productivity of research activities and the significance of its results, the authors consider in the context of the problems (larger problems) of the effectiveness of educational environments. The practical significance of research results lies in the possibility of their use for constructing criteriondiagnostic apparatus for monitoring research activities of scientific institutions (including higher educational institutions). Research methodology: systemic, metasystemic, probabilistic-statistical and qualitative approaches. Research methods: cognitive, structural, functional, and mathematical modeling; methods of graph theory, sets and relations; system-cognitive analysis; methods of quality control (theory of latent variables); methods of probability theory and mathematical statistics (first of all – a method of scree), methods of analytical geometry; methods of the mathematical theory of limits

Description
The presence of an ethnic component at economic space of the territory allows gaining synergy effect and increasing competitive advantages of the region. In the article, it is revealed that the clustering of business activity in the sphere of ethnic economy will promote growth of economy of the Krasnodar region, increase in efficiency of interaction of subjects of small and medium business and growth of their internal potential in the added economic conditions of managing. Options of agro-industrial clusters are offered and the conditions necessary for creation of these integration forms of managing are defined. Our way to a judgment, the modern economic policy pursued by organs of the regional power shall be directed to maximizing ethnoeconomic potential of economic space of the territories. Creation of ethnoclusters allows not only to increase efficiency of ethnic production by means of implementation of innovative technologies in case of manufacture of competitive production, but also to use possibilities of waste-free production, promotes implementation of culture of traditional environmental management, allows ethnoses to offer the made production in the international market. The difficulties interfering effective functioning of the Cossack farms are revealed. It is defined that use of model of the Cossack farms of innovative type at the level of the region will allow to solve a row of tasks: 1) to increase production of agricultural production; 2) to provide inflow of income to the budget; 3) to increase quality of the produced food; 4) to provide growth of competitiveness of regional producers; 5) to increase employment of the population involved in agriculture; 6) the food market will act as the "growth point" generating pulses of development of other local markets of the region

Description
The article gives results of research of the process of abrasive wear of samples made of Steel 45, U10 and with applied composite surface layer "nickelmulticomponent material with shape memory effect (SME) based on TiNi". For the tests we have chosen TiNiZr, which is in the martensite state and TiNiHfCu, which is in the austenitic state at the test temperature. The formation of the surface layer was carried out by high-speed gas-flame deposition in a protective atmosphere of argon. In the wear test, Al2O3 corundum powder was used as an abrasive. It is shown that the wear rate of samples with a composite surface layer of multicomponent materials with an SME is significantly reduced in comparison with the base, which is explained by reversible phase transformations of the surface layer with an SME. After carrying out the additional surface plastic deformation operation (SPD), the resistance of the laminated composition to abrasion wear is greatly enhanced, due to the reinforcing effect of the SPD. It is recommended for products working in conditions of abrasive wear and high temperatures to use the complex technology of formation of the surface composition "steel-nickel-material with high-temperature EPF", including preparation of the surface of the substrate and the deposited material, VGN in the protective atmosphere of argon, followed by SPD

TECHNICAL AND ECONOMIC PERFORMANCE OF VM32 MACHINE MULTI-COMPLEX
DescriptionThe article describes problems of economic growth of the Russian Federation, development of high-tech knowledge-intensive manufacturing industries on the basis of a fundamentally new technological order, creation and development of import-substituting production of engineering resources that relate to dual-use technology and are in the most demand by strategic organizations of machinetool, machine-building and military-industrial complexes (aircraft engineering, rocket and space engineering, shipbuilding and power engineering). We proposed some measures to improve the accuracy in the manufacture of complex and large-sized parts with weights up to 100 tons. Precision machining of the workpiece surface is directly dependent on the tooling, quality and quantity of the cutting tool (CT), as during the processing the CT wears and must be replaced. We have described the modernization of multi-machine complex and ways of increasing the accuracy, the change in the kinematics tool supply to increase the number of tools used in the processing. We made calculations of the new chain drive of the tool supply. The proposed modernization of the tools will increase the instrument amount that allows increasing the accuracy of manufacturing products. We have also made calculations of the economic effects of the tool supply modernization

Description
The article contains a block diagram of the mechanical activation process of multicomponent shape memory materials, taking into account the variety of influencing factors. We have proposed to evaluate the reactivity of the sprayed material using the energy criterion (energy intensity), determined by the additivity concept as an energy amount of the raw material and energy accumulated during mechanical activation. Power consumption of the raw material depends on the chemical and phase composition and is determined based on the similarity between the melting energy, plastic deformation and fracture on the thermodynamic characteristics and diagrams of the systems. The energy stored in the MA is determined on the basis of X-ray structural analysis. We have demonstrated that with increasing of grinding precision there is growth in the number of active centers, which enables nanostructurization of surface layers in high-velocity oxygen-fuel spraying (HVOF). According to the study, we have developed practical recommendations for effective implementation of mechanical activation of the shape memory material

ANALYSIS OF QUALITY INDICATORS OF AUTOMATIC CONTROL SYSTEMS WITH NONLINEAR APPROXIMATION CONTROL LAW
DescriptionThe subject of research of this work was the study of the quality of control processes in a nonlinear automatic control system with an approximating the control law. In the known published works there are no results of such studies, which makes it difficult to synthesis a nonlinear control system for multimode objects in applied biotechnology, including technological objects of the agro-industrial complex. A comparative analysis of the quality of regulation in the transient and steady-state regimes is carried out. It is shown that the approximation method used for the synthesis of the nonlinear control law provides a linear dependencies in steady-state and close to them modes in combination with relay modes in transient regimes, which is a positive factor for improving the quality of regulation in multimode control systems. It does not necessary to determine the moments of switching the dependencies in the control law when changing modes

OBTAINING OF FREQUENCY CHARACTERISTICS FOR INDUCTION MOTORS USING THE RESULTS OF THE EXPERIMENT
DescriptionThe article is devoted to the solution of the urgent task, which is to increase the reliability of the power supply systems of enterprises for processing agricultural products. The material of the article has a research character, which consists in the fact that the obtained expressions for the frequency characteristics of high-voltage induction motors allow us to investigate the symmetric modes of their operation by means of a more efficient and simple apparatus. A number of provisions of the article have a scientific novelty, which consists in obtaining frequency characteristics for induction motors as a result of the experiment. A convenient procedure for obtaining the frequency response of an induction motor based on the results of an experiment using the mathematical model of an induction motor in the coordinates of the generalized vector and the Fourier transform has been developed. As an example, oscillograms of the stator current of an induction motor of the A-12-52-4 type are given for the initial stage of the start-up. For the stator current of this induction motor, a transition is made from the phase coordinate system to the coordinates of the generalized vector. The dependences of the stator current on the D and Q axes on time are constructed. The real and imaginary parts of the frequency characteristic of the engine are calculated for sliding s = 1, the calculations are illustrated by the corresponding graphical characteristics. The results of the study are proposed to be used for the calculation of transients in power supply systems for enterprises engaged in the processing of agricultural products
