Description
Modern extraction systems are characterized by a change in the parameters of the production cycle under the influence of a number of causes caused by the structural dynamics of systems. Information systems can successfully function by solving the tasks of collecting, processing, analyzing and distributing real-time information, which involves the use of modern information technology methods. With increasing requirements to the volume, speed and quality of information on the progress of extraction processes, modernization of information systems is required, allowing to make informed decisions by management structures. In the article the regularities of mass transfer of n-components in carbon dioxide of the solid-liquid system are considered. The effect of spontaneous interfacial convection in the mass transfer of individual components under the influence of an electromagnetic field of low frequency is detected. The joint mass transfer of extractive substances during spontaneous interfacial convection leads to an increase in the mass transfer coefficient of eugenol compared to its diffusion mass transfer

Description
At present, the state management of labor protection in Russia adheres to the goals of harmonizing the domestic legislation with the best world practices in this field, eliminating internal contradictions in legislation and building an active management system for labor protection provided that a «favorable climate» for the conduct of business activities is provided. The regulatory and legal state regulation of labor protection forms the basis for the development and implementation of a set of measures to create conditions for maximum protection of life and health of workers. The authors consider the modern legal framework and standards in the field of management of labor protection in the organization. Reflects the changes that have occurred in the Russian labor legislation regarding the employer's duty to create and maintain a labor protection management system. The aspects of introduction of the health and safety management system are considered taking into account the requirements of the draft international standard ISO/DIS 45001 «Occupational health and safety management systems - Requirements with guidance for use». It is shown that one of the modern directions of standardization in the field of labor protection is the development of risk management and an analysis of foreign practice of legal regulation of issues in the field of occupational safety. The article is intended for specialists in documenting processes carried out implementation, operation and maintenance of a health and safety system, and on students of higher education institutions and teaching staff

CONSTRUCTING A MATHEMATICAL MODEL OF PRICING FOR REAL ESTATE IN KRASNODAR
DescriptionThis study proposes a method of determining the cost of 1 sq. m. apartment on the example of Krasnodar, which is especially important in connection with the necessity of reliable and valid assessment of the property value in a modern market economy. We have performed an analysis of data on apartments in Krasnodar from the site of the Regional Energy Commission - prices and tariffs department of the Krasnodar region. We have also had an exploratory analysis of available data on the subject of emissions and insignificant data (by constructing line graphs and scatter plots); we have also checked for possible dependencies between observations and between variables (built correlation matrix). We have selected variables is linear, the regression model for the variable "cost of 1 sq. m the total area, ths. rub. "(multiple regression). Using regression analysis as a method of mathematical statistics we have revealed a form of analytical dependence of the result of the predictor variables and the degree of this dependence

INNOVATIONS IN THE TECHNOLOGY OF DRY BREAKFAST PRODUCTS MANUFACTURING
DescriptionThe intense rhythm of people's lives in many countries has led to the need to develop and produce «fast food» products. They include dry breakfasts of a porous macrostructure in the form of rods, bars, and flakes, made from cereals, legumes, potatoes and dried fruits. Over the past 10 years, ready-to-eat foods that do not require heat treatment have become popular, the range of breakfast cereals has significantly increased, air grains, pads with filling, asterisks and rings have appeared. The global trend of consumption of slowly digestible carbohydrates predominates. Corn flakes and blown grain began to be used as supplements to soup instead of toast, served for tea and coffee. However, the problem of making and marketing specialized dry breakfasts has not yet been fully solved. The aim of the research is to expand the range of specialized dry breakfasts for people with high physical and mental loads. The tasks of modernizing technology and equipment for the production of dry breakfasts were solved. The methods of preparation for extrusion of easily oxidized in the air raw nuts were developed. Formulations of dry breakfasts for people with high physical and mental loads were developed. The objects of the research are analysis of existing technological schemes, grain, fruit and nut raw materials. We used classical methods of research to determine the composition of proteins, lipids and carbohydrates, as well as modern instrumental methods for assessing the qualitative composition of raw materials, semi-finished products and finished products. The research results include the modernization of technology and equipment for the production of breakfast cereals. Formulations of ready-made breakfast cereals with the addition of cereals, dry fruits and nuts have been developed, in order to improve the quality characteristics and nutritional value of the extrudates. The proposed technology and developed recipes are promising for introduction into production

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
