In this paper, we explore the feasibility of controlling the circular motion of the implant in a non-contact manner by controlling the change of the external magnetic field in a magnetic stereotaxic system. The change of the external magnetic field was simulated through computer simulation experiments, so as to control the circular motion of a small permanent magnet in a non-contact manner, and in the actual experiment, the slide rail system was equipped with a large permanent magnet to form an external magnetic field, and the operation of the slide rail system was controlled by an Arduino microcontroller. The results of computer simulation experiments were verified, and the feasibility of non-contact control of the circular motion of the implant was clarified.

The article proposes its own method of providing high availability for configuration management software. The current state of the electronic resources management sphere was examined, the reasons for the use of automation tools were provided. The advantages of using configuration management software were analyzed, examples of using Infrastructure as Code and GitOps approaches to automate the deployment and scaling of electronic resources were given. The existing methods of ensuring high availability were analyzed. The development of our own method of ensuring high availability was carried out. The resulting method of providing high availability is based on the Raft consensus algorithm and the software system clustering approach and extends them with its own solutions. The algorithm of the proposed method was developed, the resulting flowchart of the algorithm and individual steps of its implementation were described in detail. The efficiency of the developed method was evaluated. An a priori ranking of a number of factors that evaluate the effectiveness of automatic recovery strategies and methods was conducted. The analysis of the results has shown that the proposed method implements the most important factors for experts, and in terms of RTO and RPO, the method can work on a par with existing popular disaster recovery strategies.

Conditions for optimal stabilization of diffusive stochastic dynamic systems with external disturbances have been obtained. The purpose of this work is to find the stabilization conditions of diffusive stochastic dynamic systems with external random disturbances. The research topic is relevant because the results of the work will allow to investigate the stabilization of dynamic stochastic systems of a random structure, which makes it possible in many cases to stabilize an unstable stochastic system when certain conditions are met.
