A SCIENTOMETRIC INTELLIGENT MEASURING SYSTEM OF RSCI DATA BASED UPON THE ASK ANALYSIS AND EIDOS SYSTEM

abstract 1221608014 issue 122 pp. 157 – 212 31.10.2016 ru 641
Adequate and effective assessment of the efficiency, effectiveness and the quality of scientific activities of specific scientists and research teams is crucial for any information society and a society based on knowledge. The solution to this problem is the subject of scientometrics and its purpose. The current stage of development scientometrics differs greatly from his previous appearance in the open as well as paid on-line access to huge amount of detailed data on a large number of indicators on individual authors and on scientific organizations and universities. The world has well-known bibliographic databases: Web of Science, Scopus, Astrophysics Data System, PubMed, MathSciNet, zbMATH, Chemical Abstracts, Springer, Agris, or GeoRef. In Russia, it is primarily the Russian scientific citing index (RSCI). RSCI is a national information-analytical system, accumulating more than 9 million publications of Russian scientists, as well as the information about citation of these publications from more than 6,000 Russian journals. There is too much information; it is so-called "Big data". But the problem is how to make sense of these large data, more precisely, to identify the meaning of scientometric indicators) and thus to convert them into great information ("great information"), and then apply this information to achieve the objective of scientometrics, i.e. to transform it into a lot of knowledge ("great knowledge") about the specific scientists and research teams. The solution to this problem is creating a "Scientific smart metering system" based on the use of the automated system-cognitive analysis and its software tools – an intellectual system called "Eidos". The article provides a numerical example of the creation and application of Scientometric intelligent measurement system based on a small amount of real scientific data that are publicly available using free on-line access to the RSCI

SPECIAL CASES OF INVERSE MATRICES

abstract 1301706071 issue 130 pp. 975 – 981 30.06.2017 ru 641
The inverse matrix for the square matrix A of order n with coefficients of some field exists, as it is known then and only then, when its determinant is not equal to zero. If the matrix A has a certain type (certain structure), then an inverse matrix A-1 should not have exactly the same structure. Therefore, it is interesting to describe such square matrices A, which have an inverse matrix A-1, having the same structure as the matrix A, under certain conditions. For example, a subdiagonal matrix with nonzero elements on the main diagonal has an inverse matrix over a field of characteristic zero, having also the form of subdiagonal matrix. Similarly, an inverse matrix towards symmetrical or skew-symmetric matrix is also symmetric or skew-symmetric accordingly. Also, the matrix inverse to non-degenerate (nonsingular) circulant will be a circulant itself, and finally, the matrix inverse to nonsingular quasdiagonal matrix D will be quasdiagonal itself, and will have the same partitioned structure as D. Thus, there is a problem of determining these types of nonsingular matrices that have an inverse matrix of the same type as a given matrix. In line with this problem in the present study it is determined such type of matrices for which an inverse matrix has the same type, at that the conditions are identified in explicit form, ensuring the nonsingularity of the matrix. The matrices of three orders are shown in detail. These results allow determining the characteristics of fields over which there are inverse matrices of the considered types

abstract 1201606078 issue 120 pp. 1188 – 1198 30.06.2016 ru 642
The article covers the problems of the classification of the crime under Article 159.1 of the Criminal Code of the Russian Federation, and its delimitation from certain related offenses. The article analyzes a definition of the area of lending as well as the definition of a bank or any other lender. The article also analyzes a subject of a crime and the subjective aspect of a crime. The author pays special attention to the analysis of the ways (methods) used to commit fraud in the area oflending. The article considers the question of whether the known to be false or misleading information provided to a bank or other lender is the evidence for the crime stipulated by Article 159.1 of the Criminal Code of the Russian Federation. The article encourages the exchange of the opinions upon the problem of the application of the law on fraud in the area of lending. The author indicates the need for some changes in Article. 159.1 of the Criminal Code of the Russian Federation and the adoption of a new resolution of the Plenum of Russian Supreme Court, which will resolve difficulties in qualifying fraud in the area of lending

SIMULATION OF BALL LIGHTNING IN CONDUCTING ENVIRONMENT

abstract 1301706027 issue 130 pp. 348 – 378 30.06.2017 ru 642
In this work, a model is developed to describe the formation of streamers, plasmoid, and ball lightning in a conducting medium. To describe the contribution of the conductivity currents, we modified the standard electrostatic equation taking into account the vortex component of the electric field. As a result of this generalization, a system of parabolic-type nonlinear equations is formulated that describes the formation of streamers, plasma long-lived formations and ball lightning. As is known, in laboratories it is possible to create a plasmoid with a lifetime of 300-500 ms and a diameter of 10-20 cm, which is interpreted as a ball lightning. With high-speed photography, a complex structure is detected, consisting of a plasmoid and surrounding streamers. Within the framework of the proposed model, problems are posed about the formation of a plasmoid and the propagation of streamers in an external electric field. In this model, the plasmoid is considered to be a long-lived streamer. The range of parameters in which a plasmoid of spherical shape is formed is indicated. It is established that there are three streamer branching mechanisms. The first mechanism is related to the instability of the front, which leads to the separation of the head of the streamer into two parts. The second mechanism is associated with the instability of the streamer in the base region, which leads to the branching of the streamer with the formation of a large number of lateral streamers closing the main channel of the streamer to the cathode. In numerical experiments, the third branching mechanism observed in experiments connected with the branching of the plasmoid in the cathode region with the closure of the space charge to the anode through the streamer system was observed. The results of modeling the evolution of globular clusters in a scale of hundreds of milliseconds are given. Plasma exchange recharge modes leading to the formation of a positive or negative charge of the system are found

FREQUENCY CONVERTERS WITH IMPROVED PERFORMANCE

abstract 1151601084 issue 115 pp. 1323 – 1335 27.01.2016 ru 643
In the autonomous power supply systems there are widely used frequency converters that are able to simultaneously increase or decrease the frequency of the current and voltage stabilizing power supply. These positive properties of frequency converters can improve the operational and technical characteristics of the autonomous power supply system in the complex. The article suggests a functional diagram of a frequency converter performed on reversible rectifiers. We have presented timing diagrams illustrating the principle of its operation. The article also deals with two functional scheme of direct frequency converters executed on single-phase, threephase transformer with a rotating magnetic field. The principle of operation of these schemes has been also discussed in the timing diagrams. The proposed technical solutions for frequency converters contain a smaller amount of power electronic devices that make it possible, thereby reducing the level of electromagnetic interference, increase the efficiency and reliability of performance inverters. The considered scheme of frequency converters, can improve the technical characteristics of the autonomous power supply systems in the complex. We can significantly improve the performance of power systems through the use of modular aggregating principle of the basic functional units of an autonomous system

NOISE IN AGRICULTURAL PRODUCTION AND APPROACHES TO THE NOISE CONTROL WHILE USING EQUIPMENT AND MACHINES ON THE BASIS OF THE NEWEST TECHNOLOGIES

abstract 1211607077 issue 121 pp. 1221 – 1254 30.09.2016 ru 643
Here we present a brief survey of the occurrence of noise in agricultural production while using agricultural machinery and machines with possibility of application of the newest technologies including informational ones. It is well known, that noise is a constant component of all agricultural enterprises and it often indicates the operational condition of equipment and technical culture of enterprises. This is true about both stationary production, such as elevators, grinding plants, feed mills, corn processing plants, and tractors and harvesters. It is natural that above-mentioned mechanisms produce purposeful transformation of the movement. At the same time, any mechanism consists of separate parts that are flexibly joined with each other. In addition, it is due to this fact that the noise occurs. Thus, we should note that due to their design features and complexity of technology itself harvesters a priori are machines that create and produce noise. Noise reduction in machines and equipment is accompanied by increase of labor productivity. Thus, noise protection is an important issue. To reduce the noise a set of measures is applied but not all of them are efficient for selfpropelled machines, including harvesters. Besides, noise is one of the most important indicators of equipment quality, and in some cases, it can be the indicator of the technical level of a machine because it objectively displays inaccuracies in the manufacture of almost all parts. Therefore, noise control is an important problem that has social and economic value
