PROBLEMS AND PROSPECTS OF THE THEORY AND THE METHODOLOGY OF SCIENTIFIC COGNITION AND THE AUTOMATED SYSTEM-COGNITIVE ANALYSIS AS AN AUTOMATED METHOD OF SCIENTIFIC KNOWLEDGE, PROVIDING MEANINGFUL PHENOMENOLOGICAL MODELING

abstract 1271703001 issue 127 pp. 1 – 60 31.03.2017 ru 40
In the author's interpretation we consider concepts and methods of science, such as science, knowledge, model, gnosticism and agnosticism, the principle of Ashby, facts, empirical regularity, empirical law, scientific law, and others. We have formulated the main problem of the science, concluding that cognitive abilities of a human are limited and do not provide effective knowledge in a very large volume of data. The solution to this problem is to look at ways of automation of scientific research. Traditionally, we use information-measuring systems and automated systems research (ASNI) for this. However, the mathematical methods used in these systems, impose strict impracticable requirements to the source data, which dramatically reduces the effectiveness and applicability of these systems in practice. Instead of having to submit to the source data impracticable requirements (like the normality of the distribution, absolute accuracy and complete replications of all combinations of values of factors and their full independence and additivity) automated system-cognitive analysis (ASC-analysis) offers (without any pre-processing) to understand the data and thereby convert them into information and then convert this information to knowledge by its application to achieve targets (i.e. for controlling) and for solution for problems of classification, decision support and meaningful empirical research of the modeled subject area. ASC-analysis is a systematic analysis, considered as a method of scientific cognition. This is a highly automated method of scientific knowledge that has its own developed and constantly improving software tool – an intellectual system called "Eidos". The system of "Eidos" has been developed in a generic setting, independent of any domain and can be applied in all subject areas, in which people apply their natural intelligence. The "Eidos" system is a tool of cognition, which greatly increases the possibility of natural intelligence, just like microscopes and telescopes multiply the possibilities of vision (but in this case only if you have this possibility). The study proposes a new view of the models: phenomenological meaningful model, which is currently represented only by systemic cognitive models, and which is currently in the middle between empirical and theoretical knowledge. The system called "Eidos" is considered as a tool of automation of the learning process, providing meaningful synthesis of phenomenological models directly on the basis of empirical data

SMALL-SIZED MACHINES CREATION VIA ENGINEERING GEOMETRY AND COMPUTER GRAPHICS METHODS

abstract 1271703005 issue 127 pp. 126 – 137 31.03.2017 ru 39
A number of small-sized machines for division of loose materials on the basis of screw drums created with use of engineering geometry and computer graphics methods, in particular of the engineering geometry section: curves and surfaces. In these machines, unlike the known ones, the effect of the movement of bulks on the curvilinear surfaces of screw reels with imposing of low-frequency fluctuations from the vibrator on this main movement is used. Such addition of two movements does not only increase productivity, but also provides self-cleaning of the sifting surfaces of screw drums. The standard machine’s schemes are presented with use of low-frequency fluctuations on the basis of the screw drums made of several screw punched strips with smooth screw lines on perimeter and also of screw drums of only one of punched strips with various form of cross section of the sifting surface

abstract 1271703010 issue 127 pp. 193 – 203 31.03.2017 ru 37
Based on the complex of studies carried out, the formulation of wafers (wafer sheets) enriched with food additives "Powder from the tubers of Jerusalem artichoke" and skimmed sunflower lecithin was developed, as well as the formulation of fat filling enriched with a complex of food additives "Powder from tubers of Jerusalem artichoke", "Powder from hips" And low-fat sunflower lecithin. A recipe was developed and an assessment of the organoleptic and physicochemical parameters of enriched waffles with a filling was made. The storage period, ensuring safety and maximum preservation of consumer properties, was established. The study of the nutritional value of the developed waffles with filling allowed to establish that in comparison with the control sample they contain inulin and vitamin C, while the degree of satisfaction of the daily demand for these nutrients with consumption of 100 g of the developed product is 16.46 and 24.65% respectively. In addition, the developed products, in comparison with the control sample, are characterized by an increased content of dietary fiber, potassium, magnesium, phosphorus, iron, vitamins B1, B2 and B6

DEVELOPMENT OF NEW DESIGNS OF MAGNETIC MECHANICAL INDUCTION MOTORS AND METHODS OF MANUFACTURING

abstract 1271703024 issue 127 pp. 363 – 379 31.03.2017 ru 7
Based on the analysis of domestic and foreign scientific and patent literature, options for reducing the weight of electro technical steel in the magnetic circuits of electrical machines are explored. We have carried out a search for the best options of technology for the manufacture of magnetic cores of the stators of induction motors, aimed at increasing the utilization factor of electrical steel and improving the energy performance of electric machines. All options are described in detail and illustrated by drawings. We have listed the advantages and disadvantages of each method of manufacturing magneto-wires and the reasons why certain proposals of manufacturing technology cores have not been implemented in mass production. A variant of technology of manufacture of annular magnetic cores for mechanical induction electric motors is offered. The essence of mechanical design is to replace the laminated stator and rotor twisted from a strip of electrical steel, wound in the form of a ring with the simultaneous breaking-hell grooves with variable pitch under the stator windings and squirrel cage of the rotor coils. The effectiveness of the use of volute stator in mechanical electrical machines is confirmed in frequent controlled asynchronous torsion engine when tested pilot batch of the mechanical single-phase asynchronous motors for washing machines. This technology almost completely eliminates the problem of technological wastes of electro-technical steel regardless of the form of the stator bore (cylindrical, conical, flat end or flat line); it allows fully automate the manufacture of magnetic cores, greatly simplifies the stamps, makes them more durable

NEW SCIENTOMETRIC INDICATORS RESISTANT TO ARTIFICIAL “IMPROVEMENT”

abstract 1271703038 issue 127 pp. 557 – 583 31.03.2017 ru 14
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
