The phenomenon of synchronization in graph networks of coupled oscillators is discussed. To describe interactions between oscillators (neurons), a finite-dimensional first-order Kuramoto model without inertia is used. By means of parallel computing technology, a computational experiment has been carried out to simulate the time evolution of such networks for the number of oscillators n from 4 to 40 and for various values of the coupling coefficient K, 0≤K≤30. The influence of chosen coupling topology (including random topologies) on the amount of time required for the network to reach the complete synchronization state is considered.

The presented study is relevant due to the need for primary school teachers to have effective ways of organizing the development of the emotional sphere of younger students using animation. Development of universal competences among primary school students through classroom and extracurricular activities is particularly important in the current stage of society's progress. However, the educational system remains largely focused on providing students with a prepared system of knowledge, skills, and abilities based on successful learning of academic disciplines' educational programs. In this regard, it is necessary to modernize the system of primary education so that it becomes a field for the formation and development of the personality of students, which meets the needs of society. Animation is an effective means of developing the emotional volitional sphere of primary school students. The article aims to describe the results of a natural pedagogical experiment to test the developed model for organizing an animation studio's work for the emotional development of younger students. The results are of practical interest, as primary school teachers can use such model for organizing the work of an animation studio for the emotional development of younger students, the «Diary of Emotions» and a set of tasks using animation. The study's theoretical significance lies in expanding ideas about emotional development and determining the structural components of the system, their content, which are included in the described model for organizing the work of an animation studio for the emotional development of primary school students. The practical significance of the study is due to the development of a model for organizing the work of an animation studio for the emotional development of primary school children and the compiled training tasks for students, developed by the «Diary of Emotions» as a means of working in an animation studio.

The article presents an approach to assessing the reliability of an aircraft engine fuel system using a simulation model. The developed model allows us to assess the level of reliability of the fuel system units of an aircraft engine depending on changes in the operating conditions of the aircraft.

The article describes how, in teaching robotics on ROS, virtual practice in a three-dimensional environment, assembling software from nodes and packages, and transition to real hardware are combined. It explains how practices from web software development can be transferred to robotic systems that are more demanding for the following reasons: the cyber-physical loop is safety-critical; scenarios in simulation and in the field differ; time and hardware are limited. The argument draws on the ROS 2 survey, guidance on runtime verification and field testing of ROS-based systems, a review of regression-test optimization for autonomous ROS stacks, a systematic survey of software testing in robotics, and a description of the Robotics-Academy environment. Practical guidelines are formulated for organizing courses and team projects.

The article discusses how robotics education on ROS combines virtual practice in a three-dimensional environment, assembling software from nodes and packages, and transition to real hardware. It explains how practices from web software development map onto robotic systems that are more demanding because the cyber-physical loop is safety-critical, scenarios differ between simulation and field tests, and time and hardware are limited. The argument draws on the ROS 2 survey, guidance on runtime verification and field testing for ROS-based systems, a review of regression-test optimization for autonomous ROS stacks, a systematic survey of software testing in robotics, and a description of the Robotics-Academy environment.
