A mathematical model has been formed for calculating the elastic characteristics of a generalized material based on the properties of a transversely isotropic fiber and an isotropic matrix. The problem of choosing the parameters of materials is formulated as the problem of minimizing the objective function on a parallelepiped set of admissible solutions. To solve it, classical and modified self-organizing migration algorithms of global optimization belonging to the group of metaheuristic are applied. Recommendations on the selection of the best parameter values are obtained.

The article discusses the issues of developing an ETL process for a data warehouse based on open source technologies, instead of private software supplied by the vendor. The process allows you to deliver data from the source to the consumer, focusing on the speed of delivery, the resources spent and the convenience of development. The architecture for solving the problem with a description of the processes being replaced is presented, data transmission over a new process is implemented. Modern tools used to work with data are involved, methods of interaction with them and selection of technical characteristics for the process are described.

The paper proposes a method for calculating the complexity of game tests. Calculations are carried out for the PLines gaming system. Brief information about the PLines system is provided.

A field of Industry 4.0 is one of the most perspective with respect to research and optimization of production and industrial problems. The main problems in this field are connected with necessary analysis and processing of a huge data, which have a different native and sources. Particularly, the data from various automatic sources, as well as getting due to human management, become far away from each other both from the structure point of view and the native meaning. And there often occur, that such a different data in integrated form could contain a significant information for analysis, and moreover for a transformation of the technological process. At the same time, it is rather difficult to provide an analysis in frame of a significant asynchrony, and sometimes it becomes to a practical unsolvable problem. In this regard, the problem on developing of specialized methods for collecting, storing and processing big data of various structures are becoming fundamentally relevant. This is the purpose of the present work, which proposes a new method for organizing data based on the concept of object relations as a universal structure for production modeling. The proposed method is based on the concept of an "object", which is any entity of the production chain (plant, workshop, machine, production operation, unit of production, etc.) The key difference between the method of object relations and agent modeling is the fact that no behavioral scenarios are imposed on objects. Thus, the "object" structure turns out to be authorized to enter into any relationship with other "objects" within the framework of the model under consideration, which in turn allows to accumulate various kinds of data into a single hierarchy and guarantees the reliability of analysis at any level. The proposed method of object relations has been applied at several full-scale production sites, thereby confirming its stability and operability. The paper provides an analysis of key performance indicators of the application of the method of object relations to solve the problem of forming a technological passport of a product at the steel production, and also discusses ways of further development.

The problem of fuzzy relation transitivity checking and transitive closure finding is considered in the paper. Solution algorithms are formulated and corresponding software is described. A logical scheme is given.

The article describes an approach based on a formalized description of technological techniques for performing exercises in information technology courses. The language of description of such techniques is given, which makes it possible to organically fit technological features into the text of the exercise in natural language. Fragments of real scenarios of practical training in information technology are given.

The paper discusses the issues of developing an information system for diagnosing the motivation of educational and cognitive activity of schoolchildren. The information system used the methods "Diagnostics of school motivation of primary school students" and "Diagnostics of the structure of the student's educational motivation". According to the first method, data of 66 primary school students were collected. The second method collected data from 44 students (12 students from 5th grade, 14 students from 11th grade and 18 students from 2nd grade). The analysis shows that primary school students lack low motivation to study. Students of the fifth and eleventh grades have the most pronounced motive of "Self–development", and second graders have the "Position of a schoolboy". Which suggests that middle and high school students are interested in the process and the result of their activities and strive for self-development, and younger students have a sense of duty and responsibility for learning.

The work is aimed at improving the cultural level of correspondence in dialog systems. The key feature of the work is its focus on real–time use and ensuring sustainable detoxification, taking into account the specifics of dialog communication (typos, noise symbols, transliteration, etc.). The solution offers the use of a neural network approach and software processing to obtain embeds of tokens and the subsequent solution of the classification problem. Unlike traditional message filters, the task is to preserve the meaning of the source text by clearing it of toxic content. The operability of the system can be checked on the basis of the Telegram messenger, in which the model is presented in the form of a bot. The system itself is deployed on the basis of Serverless technology from a cloud provider, which allows it to adapt to peak loads and at the same time be easy to maintain.
