In recent years, thanks to the rapid progress of the technology for creating invisible ultraviolet LEDs and the technology for detecting ultraviolet rays, ultraviolet communication has gradually become an urgent object of research due to its inherent advantages: low solar background noise, the possibility of organizing communication in the absence of direct visibility (NLOS) and good stealthiness. The strong scattering characteristics of the ultraviolet signal in atmospheric render ultraviolet waveband the ideal choice for achieving NLOS optical communication. This article reviews the research history and status of ultraviolet communication both in Russia and abroad, and especially introduces three main issues of ultraviolet communication: channel model, system analysis and design, light sources and detectors. For each aspect, current open issues and prospective research directions are analyzed.

This article analyzes the territorial and dynamic aspects of the propagation of information in social networks. The results of such analysis made it possible to draw a conclusion about the formation of practically a hierarchical structure of interconnections between manipulative influences (MI) different in nature, aimed at individual groups of individuals and society as a whole. A set of models for the implementation of the confrontation with informational influences in social networks aimed at achieving destructive goals has been synthesized. Very important results obtained by the authors in this study are the analytical dependencies on various factors for a certain amount of time required for maximizing the number of “infected” users of social networks due to the implementation manipulative influences; extremum of those who are in the so-called “latent” state; reaching the level of 95% of the number of “infected” of the total number of users living in certain settlements or in a certain territory. The success of the implementation of this study and its practical significance, primarily due to the application of the principle of clustering by the authors to mathematical model various situations regarding the propagation of information on a homogeneous territory.

This article analyzes the influence of the characteristics of ultrasonic transducers on the performance of a measuring system using ultrasonic sensors to monitor the position of the moving part of the equipment and control the whole process. The purpose of the analysis is to optimize the control protocol scheme. Ultrasonic transducers are used as a transmitter and receiver of ultrasonic vibrations, the main structural element of which are piezoelectric elements. The physical principle of the piezoelectric element action is stated. Selecting an ultrasonic transducer, the following pairs were tested, including a transmitter and a receiver: AW8R40-10OA00 / AW8T40-10OA00, AW8R40-12OA01 / AW8T40-12OA01 (manufacturer AUDIOWELL), TCT40-10R1 / TCT40-10T1 (manufacturer MEC) and UCE10T-40R-WA / UCE10T-40T-WA. All of them have a resonant frequency of 40 kHz. The transducer characteristics such as sound pressure level SPL, sensitivity, bandwidth, divergence angle, capacitance, maximum applied voltage, operating temperatures are considered. The methods of analysis are proposed and the study of the influence on the functional work of the circuit of the following factors is conducted: frequency; the number of pulses of the generator; distance from source to receiver; angular displacement transducers. The results obtained from the test make it possible to develop recommendations for the selection of ultrasonic transducers to be used as a part of a displacement sensor and optimize their operation. The displacement sensor based on ultrasonic transducers was tested in the PIKA-19 set of equipment for static sensing, manufactured by the PIKA-TECHNOSERVICE Scientific and Technical Center LLC.

In this paper, we study the frequency properties of the multi-step comb and counter-comb microstrip structures with various methods of their excitation. It is shown that with a combined method of its excitation, it has a significantly higher frequency selectivity. The results of a comparative analysis of two-, three-, and four-resonator structures are presented, in which a significant number of working attenuation poles at finite frequencies are formed, which deter-mines the increased frequency selectivity of microstrip filters based on these structures with a significantly limited number of resonators.

A rat-race coupler has been developed that performs an equal-half division of the microwave power coming to one of its inputs. The area of the compact topology without input lines is 776.25 mm2, which is 80.35% less than the area of the usual implementation of the coupler. This result is obtained due to the usual replacement of transmission line segments with their analog in the form of electrodynamic structures. Design of structures was carried out in the NI-AWR program. A mock-up of the proposed device was made, and the measured characteristics are in good agreement with the simulation results.

Research focused on the problem of developing digital adaptive equalizer in the frequency band of wideband HF communication to overcome the negative effect of nonlinear phase dispersion. Developed methods, algorithms and software are supported by the SDR technology and were implemented with the use of the USRP N210 platform. They use state-of-the-art approaches in digital signal processing, including those elaborated by the authors. Verification of methods, algorithms, and software for adaptive equalization was carried out in full-scale experiments on LFMCW sounding over the Cyprus-to-yoshkar-Ola propagation path of length of 2600 km. Besides, the specific objective of the research was studying equalization efficiency in megahertz-bandwidth channels the single-mode (1F mode) propagation band.

This paper is a research of the communication system with hyperphase modulation based in a surface-spherical ensemble of signals, that contains 18 signal points. The communication system studied in this paper consists of a transmitter with hyperphase modulator, a channel with additive white Gaussian noise, and a receiver with a hyperphase demodulator. A simulation model of the communication system has been developed in the Matlab Simulink software package. With the help of the simulation model, it is confirmed, that the application of the signal with hyperphase modulation for communication systems is possible. The probabilities of symbolic and bit errors are obtained for various signal-to-noise ratios in a Gaussian communication channel. A comparative analysis of the characteristics of the signal with hyperpase modulation is carried out in comparison with the classical types of modulations. The prospects of the use of signals with hyperphase modulation in data transmission systems, including satellite-based, are estimated in this paper.

The article is devoted to the analysis of the use of blockchain technology for self-organization of network communities. Network communities are characterized by the key role of trust in personal interactions, the need for repeated interactions, strong and weak ties within the network, social learning as the mechanism of self-organization. Therefore, in network communities reputation is the central component of social action, assessment of the situation, and formation of the expectations. The current proliferation of virtual network communities requires the development of appropriate technical infrastructure in the form of reputation systems - programs that provide calculation of network members reputation and organization of their cooperation and interaction. Traditional reputation systems have vulnerabilities in the field of information security and prevention of abusive behavior of agents. Overcoming these restrictions is possible through integration of reputation systems and blockchain technology that allows to increase transparency of reputation assessment system and prevent attempts of manipulation the system and social engineering. At the same time, the most promising is the use of blockchain-oracles to ensure communication between the algorithms of blockchain-based reputation system and the external information environment. The popularization of blockchain technology and its implementation in various spheres of social management, production control, economic exchange actualizes the problems of using digital technologies in political processes and their impact on the formation of digital authoritarianism, digital democracy and digital anarchism. The paper emphasizes that blockchain technology and reputation systems can equally benefit both the resources of government control and tools of democratization and public accountability to civil society or even practices of avoiding government. Therefore, it is important to take into account the problems of political institutionalization, path dependence and the creation of differentiated incentives as well as the technological aspects.
