NEW SCIENTOMETRIC INDICATORS RESISTANT TO ARTIFICIAL “IMPROVEMENT”

abstract 1271703038 issue 127 pp. 557 – 583 31.03.2017 ru 353
The 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

JUSTIFICATION OF DESIGN PARAMETERS OF THE ACTIVE RING OF A CENTRIFUGAL DISC WITH THE FILING OF MATERIAL ALONG BLADES

abstract 1231609113 issue 123 pp. 1659 – 1670 30.11.2016 ru 355
There has been developed the design of the single disc centrifugal apparatus with the feed of the granular material along the blades. The scattering disc consists of blades, on the top shelf there is a flat disc with air intake windows (deflector). The purpose of the deflector is to eliminate the reflection of particles at the moment of contact with the blade and create a passing air flow to increase the range of flight of the particles. The analysis of the constructive scheme of the scattering disk showed that the amount of air coming inside the scattering disk is affected by the width of the window and the tilt angle of the deflector body. There was determined the dependence of the window width from the angle of the deflector body and height. Based on the analysis of the design there have been determined the limits of setting the window width and the tilt angle of the deflector body. The angle of the deflector body changes in the rate of 90 to 320 . Increasing the tilt angle of the deflector body leads to a proportional reduction of the window width. There have been set the intervals of variation of factors. There have been chosen the symmetrical composite plan of the second order and have been made a matrix of the experimental design. As a function of the response factor there have been taken a relative accuracy coefficient. The implementation of the experiment allowed us to determine the value of the regression coefficients. The adequacy of the regression equation to the equation obtained was performed by the Fisher test. It was determined that the equation adequately describes the technological process. For the analysis of this equation it was turned to the canonical form by moving the origin to a new point and turning at a certain angle of 14,950. The analysis of the canonical equations allowed the authors to determine the optimal values of the studied factors. The window width of the deflector is 22 - 25 mm, the angle of the body of the deflector is 8 - 120

RESEARCH OF USEFUL POWER OF THE STIRLING-BASED ENGINE AND THE MECHANICAL EFFICIENCY OF ELECTROMECHANICAL ANALOGY

abstract 1241610059 issue 124 pp. 887 – 896 30.12.2016 ru 356
We have presented a table of analogues of mechanical and electrical quantities of a thermal power plant, which shows the relation between the useful power of the engine and mechanical efficiency, as well as the relationship between engine parameters and regime of its operation; we have also developed an electro-mechanical analogy, which helped to get the expressions linking the useful engine power with shaft speed, engine performance, coefficient of mechanical resistance and mechanical efficiency with speed, coefficient of drag and engine performance. Similar expressions were obtained for the relations of these variables with other sets of parameters. The article also shows corresponding graphs. The expressions for the maximum net power and corresponding speed of rotation was found. Thus, the efficiency isЅ. It is shown that in larger (compared with the extreme) speed, the mode is less efficient than with the smaller, for the same useful power. A method is presented to measure the important characteristics of the finished engine – motor operation and its rotational drag coefficient used in the resulting expressions

SYSTEM OF PATIENTS SUPPORT USING A DATA TERMINAL (ON THE EXAMPLE OF SMARTCITY COMPANY)

abstract 1221608049 issue 122 pp. 714 – 724 31.10.2016 ru 358
In February of 2016, the Russian Ministry of Health confirmed the guidelines on functionality introduction of medical information systems for medical organizations (MIS MO). The required MIS development levels (of basic and advanced functionality), the capacity status (required and recommended) and a set of subsystems were defined there. One of the subsystems is the "Information support of patients" and all of its functions, being advisory in nature, represent the advanced set of MIS functionality, namely: the support for information terminals and screens, as well as providing the patient or his legal representatives with the access to medical documentation and background information. However, the opportunity to make an electronic appointment to see a doctor on your own plays the leading role as the most widespread and socially oriented medical service. The research is concerned with the issues of the e-registry work support (ER) via the data terminal for patients, including printing the appointment tickets, made via the data terminal. The paper suggests a new patient oriented algorithm of the prompt way to make an appointment to see the doctor. The idea is simple – avoid a large number of clicks on the ER interface tabs and immediately suggest the most appropriate time of reception, basing on previous patient visits. The algorithm was tested on the infomat software, run by "Smartcity" in MO of Krasnodar Region and used to make the appointment to see a doctor by patients on their own, without any assistance of registry staff in MIS

THE USE OF FOKKER-PLANCK EQUATION FOR ANALYTICAL REASONING OF MIXING PROCESS IN THE SCREW MIXER

abstract 1281704073 issue 128 pp. 1060 – 1069 28.04.2017 ru 358
In the current economic situation, the developing of cattle breeding is taking on special significance. It is well known that the effective way to develop cattle breeding is to increase the total number of efficient livestock. The numerous researches show that the high concentrated fodder premix diet gives the highest effect in increasing animal indicators [1, 2, 3]. Traditionally, the premix is a powder mass, which should be added into the mixture of grain components. Exact following the recipe of prepared fodder allows the maximum usage of forage potential of the concentrate components [4, 5, 6, 7]. In view of the foregoing, food enrichers have special actuality in making high concentrated fodder [8, 9, 10]. The usage of differential Fokker – Planck equation systems allows determining the laws of the mixing process of various granulated products. As a result, it becomes possible to optimize the technological process of the mixerenrichers of concentrated feed so that the resulting mixture of feed would have high quality and technological characteristics. At the same time the duration of sewer-enricher’s work and, as a consequence, the energy intensity of the technological process would accept the minimum possible values [11-16]. The given theoretical approach is based on the consideration of the motion of an individual particle contained in a loose grain mass (phase). Concerning this, it is necessary to accept a number of assumptions about making effort to the feed particles, and the velocity vectors of its initial motion should be taken into account. Taking into account the complexity of the mathematically derived differential equation, its literal analytical solution seems very difficult. Therefore, the first step of the solution is aimed at the obtaining the non-stationary diffusion equation of Fokker - Planck and the boundary conditions for isolating the only one solution. The second step of the solution is implemented by the tabulation at the grid-based points, that is, considering the differential equation not at a random point of the area, but only at the grid nodes. Moreover, it is necessary to apply the approximation of the derivatives at each node. The solution of the equation system allows determining the module of the minimum, average, and maximum values of the phase particle motion in different parts of the mixing chamber, respectively. In connection with this, the aim of the study is to substantiate the processes of motion of various types of granulated products

abstract 1341710083 issue 134 pp. 1018 – 1030 29.12.2017 ru 358
The article presents data on the development of recipes and technologies for the production of functional drinks based on cabbage juice. Theoretical and experimental justification of the selection of ingredients of plant origin for the modeling of drinks with a high content of pectin substances is offered in the article. The use of carrots, beets and cranberries is considered as an additional raw material for the purpose of expanding the range and improving the organoleptic properties of beverages. The fractional composition of pectin substances used in the raw materials was studied. The expediency of introducing concentrates of pectin substances into beverage recipes, which define the functional properties of beverages and their optimal content in the recipes was determined. The characteristics of basic parameters of new drinks based on cabbage juice are given. The results of the study of the complex forming property of the developed beverages, which confirmed their functional orientation, are presented. Experimental studies have shown that the addition of pectin increases the complex forming property of juices. Complex forming ability of cabbage juice with beet pectin in comparison with the control sample and other samples is the highest. Taking into account additional complex of biologically active compounds based on cabbage juice, this product can be used as therapeutic, prophylactic and chemoprotective

TO THE APPROACHES OF RECOGNITION AND IDENTIFICATION OF INDIVIDUALS WITH DIGITAL IMAGES IN THE TASK OF ENSURING PUBLIC SAFETY

abstract 1231609042 issue 123 pp. 630 – 639 30.11.2016 ru 359
One of the key areas of interdisciplinary research is to ensure public safety. In order to solve a number of problems within this area we can effectively use information technology and, in particular, an automated pattern recognition technology and identification of objects on digital images. There are addition problems in objects identifying process besides eliminating the influence of ambient light, angle, items of clothing and headgear. To ensure the applicability of the recognition approach to public security issues it must meet requirements of the high processing speed, the replenishment capabilities onthe-fly list of known images, and the low computational complexity of algorithms. The article deals with the main approaches to the recognition and identification of objects on digital images based on statistical approaches, as well as neural network models. We have allocate their basic features and principles, provided a brief description of each method. Consideration has been made in terms of the application for the problems of public safety, in which there is importance of the speed of the identification of the object, the ability of quickly learning for the system to accept new images and simultaneously process a plurality of input images. The analysis of the existing approaches has shown that none of them satisfy at least one or several needs, which are defined by domain problems of public safety

RESEARCH OF RESISTANCE OF PRODUCTS WITH COMPOSITE COATINGS LAYER FROM MATERIALS WITH SHAPE MEMORY EFFECT TO ABRASIVE WEAR

abstract 1281704041 issue 128 pp. 558 – 574 28.04.2017 ru 359
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
