RESTORATION OF A MODEL OF A DYNAMIC NONLINEAR SYSTEM FROM THE TIME SERIES GENERATED BY IT
DescriptionThe main task in the analysis of time series is the reconstruction of the dynamical system that generated this series. To illustrate the nature of the behavior of a dynamic system described by a nonstationary time series, a «phase portrait» method is proposed. An acceptable description of the phase space of a dynamical system can be obtained if we take instead of real variables of the system delay vectors composed of the values of the series at consecutive moments of time. Restoration in a given class of a system of differential or difference equations is performed based on the scalar time series of the observed process. In order to eliminate the measurement error and accurately represent the position of the object in the current, future, or any of the past moments, it is proposed to apply the Kalman filter using the known mathematical model of object dynamics

Description
This article is devoted to the problem of network attacks recognition, which is essential for providing network security. A research of neural network efficiency has been held. Such metaeuristic algorithms as genetic algorithm, gray wolf algorithm and firefly algorithm have been applied for the neural network learning. The algorithms’ fundamentals have been described. Multilayer perseptrone with sigmoid activation function has been selected for the task of network attack presence check. Various configurations of the neural network have been tested in order to find the optimal number of layers and neurons per layer, which ensure the least error. Learning has been performed by minimization of the average squared error between the network’s output and its target value with the help of the listed algorithms. Genetic algorithm requires accurate parameter picking in case of any network’s architecture alteration. Moreover, it is not as fast as firefly and gray wolf algorithms. Gray wolf algorithm appears to be the most effective one. However, it loses its efficiency if the number of layers is increased. Firefly algorithm proves to be the most universal one. Although it is less effective than gray wolf algorithm, it provides the most exact output even if the network’s structure is changed

USE OF GRAPE POMACE IN PRODUCTION OF FLOUR CONFECTIONERY PRODUCTS
DescriptionThe object of the study was the sweet pomace of red varieties of grapes grown in village Taman Temryuk district of the Krasnodar region. By grinding in a laboratory mill and drying in a drying oven at a temperature of not above 60 ºC, a powder is obtained from the mash. Its quantitative chemical analysis has been carried out. The mobile forms of metals and the total content of metals are determined. The content of mercury, lead, arsenic does not exceed the permissible levels of the maximum content of toxic elements in flour confectionery products. The influence of powder from grape pomace on the quality of the finished product and on the properties of the pastry test was studied, as the control sample was chosen the recipe for the sugar cookies "Carrot". A part of the flour was replaced with grape-dried powder in amounts of 1 %, 2 %, 5 % of the mass of wheat flour of the highest grade in the test. The recipe of sugar cookies with the addition of powder from grape pomace and without, calculated on 200 g of finished product, and organoleptic parameters of the finished biscuit is given. It is established that the use of grape-dried powder allows to increase the mass fraction of dry substances and to reduce the mass fraction of sugar in confectionery products, as well as to enrich them with mineral substances, microelements, which are necessary for normal functioning of the organism. Biscuits with the addition of powder from grape pomace are a good source of ballast substances reducing caloric content, which contributes to the removal of harmful substances from the body: cholesterol, heavy metal salts, etc

MODEL OF MANAGEMENT SYSTEM OF LABOR PROTECTION OF A MACHINEBUILDING COMPANY
DescriptionThe article considers a combination of the process-based and systematic approach in the management of OSH at the enterprise for the development of the OSH management system model. The OSH management system is created by the enterprise based on the model provision, the branch requirements and recommendations of the current standards. Features of the system are determined by the state of the external and internal environment of the enterprise (context). The context forms the basic requirements for the inputs of the system and determines its capabilities. An analysis of the context of the enterprise makes it possible to identify the system: describe its inputs and outputs, identify key stakeholders and consumers. Based on this analysis, a model of the OSH management system is suggested, which, in analogy with the modern model of the quality management system, allows us to identify the place of the OSH in the context of the organization, and also to clarify the interaction of the main groups of OSH

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

Description
The article presents the main directions of the application of the scree plot method in solving metrological problems in the social and humanitarian fields of knowledge (economics, pedagogy, sociology, including sciencemetry). It is known that statistical measurements in socio-economic systems are inextricably linked with the processing of primary homogeneous monitoring information. It is also known that empirical averaging (computation of the empirical mean), as the dominant method of mathematical statistics, is becoming a thing of the past, due to moral aging, inconsistency with modern requirements (primarily to measurement results in socio-economic systems); In science meteorology, this method was replaced by the scree plot method (the Hirsch index and other scientometric indicators are estimated on the basis of this method). Despite its enormous potential, the scree plot method, as an alternative to traditional methods of mathematical statistics, is very poorly used in the social and humanitarian fields of knowledge. The authors of this article have shown that this method can be successfully applied in solving various metrological tasks, not only in science (sciencemetry is a branch of science), but also in economics, pedagogy and sociology. In addition, the authors show modifications of the scree plot method, using the example of measuring (measuring) indicators in the economy, sociology and pedagogy; The relationship between the scree plot method and the theory of latent variables (qualimetry) and database technology is grounded. The authors also substantiate that the scree plot method - the basis for the formation of monitoring indicators that adequately reflect the performance of socio-economic systems. The practical significance of the results of this study is that they can be used in socio-economic and psychological-pedagogical monitoring systems (according to modern views, monitoring is an information management mechanism). Methodological basis of the research: system, sociological, competence, probabilitystatistical and qualimetric approaches (leading methodological basis is the probabilistic-statistical approach). Research methods: modeling; Methods of graph theory, sets and relations; Systemic-cognitive analysis; Methods of qualimetry (the theory of latent variables); Methods of mathematical statistics
