This work examines the functioning of a team of agents united through a network, and considers the architecture of a distributed data processing system based on an overlay network. The goal of this work is to develop a comprehensive solution that provided signal preprocessing, reliability of data storage and transmission, and high speed of decision making. The distributed key-value storage Etcd has been integrated with the implemented overlay network client by using the tun interface on each agent. The client encapsulates the transmitted IPv4 data packets for further sending through the underlying IPv6 network using a protocol that ensures reliable delivery. The solution considered in the work allows you to autonomously create quickly deployable network exchange mechanisms and guarantee data delivery with an acceptable delay in conditions of interference, jitter, fluctuations in packet delivery delay, and packet non-delivery.

This article highlights the theoretical results of analytical research in the field of the use of tethered balloons as carriers of barrier networks, which can be used as passive protection of particularly important civil and industrial facilities from unmanned aerial vehicles and other low-flying means of air attack. A diagram of an aerostatic barrier system, theoretically capable of countering air attack means, is presented. The elements of the methodology for determining the probability of damage to aircraft from cable type air barriers are presented.

It has been established that the concentration of cholesterol mesogenic esters in lubricants ambiguously affects the microrelief parameters and the tribotechnical characteristics of a steel 45 – steel 45 friction pair. %, the best indicators of friction and wear of metals, on the contrary, are realized with an increase in the concentration of cholesterol esters in lubricating compositions.
