Monitoring of the state and behavior of spacecraft subsystems based on telemetry data is designed to continuously perform the tasks of controlling, controlling and maintaining the technical characteristics of a spacecraft. Increasing requirements for the characteristics of monitoring methods inevitably leads to a revision of the control technologies used and the need to create a scientific and technical reserve in the form of approaches, methods and technologies for building promising competitive space technology, including: technologies for building integrated information support for solving the problems of monitoring spacecraft subsystems; applied object-oriented systems of artificial intelligence, neural networks and high-performance computing for control, diagnostics and decision support. Currently, the following issues of monitoring the fault tolerance and reliability of space systems are relevant: the development of concepts for flight control centers that control multi-satellite systems and imply high reliability, processing of extra-large amounts of information, autonomy of operation, transfer offunctions on board, reduced human participation in control; analysis of possible failures; substantiation of the use of the on-board system for diagnostics, monitoring and localization of failures and malfunctions, restoration of working capacity; ensuring the maximum achievable (close to absolute) safety, eliminating the catastrophic consequences of possible failures of individual elements and subsystems; development and improvement of the methodology for setting requirements, assessing and controlling the quality and reliability of spacecraft and their components; improvement of international standardization of commercial rocket and space technology; optimal integrated risk management of space activities. The work is devoted to the control and diagnostics of subsystems of communication and orientation of the spacecraft. An artificial neural network, pair and multiple correlation functions are used as a mathematical apparatus to support the operator's decision making. It is shown that the methods make it possible to detect malfunctions and failures of sensors in real time. Calculations based on data obtained from spacecraft sensors are presented.

Based on the conducted research of the influence of various parameters on the values of information and cybersecurity risks in the functioning of enterprises and organizations that widely use elements of the digital economy and have a network structure, the need for timely identification of critical nodes in the network structures used has been established. The authors propose the methodology for determining the most critical nodes of network information infrastructures to ensure their operability and the necessary level of cybersecurity. The methodology bases on the combined use of fuzzy logic, regression analysis and ranking methods in the context of the dependence of information and cybersecurity risk on many different parameters. The authors propose to solve the problem of determining the most critical nodes of network information infrastructures in two stages. At the first stage, the methods of fuzzy logic and regression analysis determine the set of parameters that most affect the value of the cybersecurity risk for the considerate network nodes. At the second stage, we identify the most critical nodes by the method of ranking nodes according to the parameters determined at the first stage. The use of the proposed methodology makes it possible to identify the most critical nodes of the network infrastructure in a timely manner, to plan the set of measures to maintain it at the required level of operability, as well as minimize possible damage and consequences from the implementation of existing threats.

The article outlines the properties of blockchain technology, according to which the content of blockchain blocks is immutable and the use of a peer-to-peer (P2P) network implies decentralized management. It describes the essence and meaning of smart-contracts and smart-views derived from them, which are involved in the process of data analysis and decision making. The article considers the papers devoted to various approaches to the problem of integration of blockchain technology and data storage. To ensure all three key aspects of information security — the integrity, availability and confidentiality of information, which is important for both government and corporate structures, the article proposes to use a private blockchain, instead of a public one. A modification of the model of an electronic decision support system containing an OLAP block, which includes a private blockchain, is developed. It is shown that this DSS model can be used as an electronic demographic DSS, which is an infrastructure for solving state problems in this area, since many of the characteristics of this model correspond to the multisectoral nature of demography.

The article describes the basic principles of operation of the finite element mesh generator SMCMGrid, which is an integral part of the SMCM software package designed to solve problems in the mechanics of composite materials and structures, which was developed at the Scientific-educational center on supercomputer modeling and software engineering of Bauman Moscow State Technical University (BMSTU SIMPLEX CENTER). The paper describes a software pipeline for constructing high-quality tetrahedral unstructured meshes for arbitrary shape B-rep models based on constrained Delaunay triangulation. We have presented the main algorithms for generating meshes on the edges and surfaces of the model, which make it possible to create the so-called simplicial complex, for which it is then possible to construct a constrained Delaunay triangulation and create the final tetrahedral mesh of the required quality. The mesh is generated in a Riemannian space with a given metric that takes into account the required characteristics of the mesh at each point of the geometric model. We gave examples of finite element meshes for various geometric models of engineering structure elements, including composite materials, and also demonstrated the adequacy of the results of solving the elasticity problem on a mesh built using the SMCMGrid generator. The results of the work led to the conclusion that the presented generator can be used to solve problems of engineering analysis and modeling.

The article describes the features and architecture of intelligent online tutor "Kak eto rabotaet: Algoritmy", which is based on modelling subject-domain concepts on the comprehension level of Bloom's taxonomy. It is designed for learning basic algorithmic structures — sequences, selection statements, and loops — using the task of building an execution trace of the given algorithm. The tutor analyzes the student's solution step by step and displays explanatory messages for every error right after it happens; the error messages include the violated domain rules and their consequences in the specific situation. It can also hint the next correct step with textual explanation of why it is correct. It allows reliable learning of new concepts without control of each exercise from the human teachers which significantly increases the number of exercises learners can perform during a course. A control-flow diagram of the algorithm can be visualized; when the student makes an error, it is displayed with a red line on the diagram. The tutor is based on the formal model of subject domain implement using Apache Jena rules over RDF graph. Teachers can create learning problems using block-based interface and them, receiving links that can be sent to their students. Students can also use the tutor on their own to explore examples of interest to them.

The paper considers algorithms for reducing the NP-hard traveling salesman problem to a two-level cooperative assignment problem and vice versa. The accuracy of the information of both algorithms is demonstrated by an example. Using the known conditions of the phase transition in the traveling salesman problem, copies of the problem were created, on which a computational experiment was subsequently carried out. The experiment is aimed at demonstrating the conservation of the phase transition when reducing one problem to another.
