A structure of a refractometric fiber-optic biosensor with microwave photonics processing of information about refractive index of the medium surrounding the sensor is proposed. The sensor is made on a linearly chirped fiber Bragg grating and contains two phase $pi$-shifts spaced along the length of the grating in its structure: one fixed in magnitude and location, the second, changing its parameters, in the fiber section with an etched cladding. Upon contact of the measured medium with a portion of the fiber containing the second phase shift, there is a change in its magnitude and frequency position, depending on the refractive index. The possibility of detecting changes in the refractive index with a resolving power of $1.5times 10^{-6}$ RIU is shown.

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 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.

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.

Dynamic adaptive streaming over HTTP provides the work of most multimedia services, however, the nature of this technology further complicates the assessment of the QoE (Quality of Experience). In this paper, the influence of various objective factors on the subjective estimation of the QoE of streaming video is studied. The paper presents standard and handcrafted features, shows their correlation and p-Value of significance. VQA (Video Quality Assessment) models based on regression and gradient boosting with SRCC reaching up to 0.9647 on the validation subsample are proposed. The proposed regression models are adapted for applied applications (both with and without a reference video); the Gradient Boosting Regressor model is perspective for further improvement of the quality estimation model. We take SQoE-III database, so far the largest and most realistic of its kind. The VQA (video quality assessment) models are available at https://github.com/AleksandrIvchenko/QoE-assesment
