The article proposes methods for increasing the efficiency of pattern recognition in images using convolutional neural networks in conditions of insufficient reference images. It is proposed to use various kinds of image transformations to generate new images and increase the training sample volume. In particular, methods of scaling, adding noise, blurring, etc. are proposed. In addition to standard image transformations, it is supposed to increase the database by presenting patterns using a doubly stochastic model. In addition, the need for the use of regularization in training is noted. The recognition results are compared for two convolutional neural networks that differ only in the number of neurons for different initial data. It is shown that the highest recognition accuracy is provided by a network trained on a large number of augmentations in combination with images generated by a doubly stochastic model.

A Butler matrix scheme with the possibility of forming four independent radiation patterns is proposed. The dimensions of the circuit under consideration were reduced due to the miniaturization of all directional couplers included in the matrix. The dimensions of the couplers were reduced using artificial transmission lines - this allowed to reduce the matrix area by 73.15% relative to the matrix in the standard version. Theoretical and experimental characteristics are given, according to which it was established that the operating frequency band of the compact matrix is already 10%. The proposed matrix can be easily manufactured using standard methods for the manufacture of printed circuit boards.

The paper presents the results of designing a data collection system aimed to prevent pressure sores and ulcers in immobile patients, most of the time are in a wheelchair. Three variants of sensor part of system are discussed. In all variants, two similar linearly chirped fiber Bragg gratings (LC-FBG) are used forming one system sensor: first for patient pressure sensing, second for temperature compensation. In first variant, we used classical LC-FBG. In second one, both gratings in center had one phase $pi$-shift. The use of such gratings will reduce the cost of the spectral interrogation system, which limits the use of similar fiber-optic systems in medical practice. The interrogation system used for these type sensors belongs to microwave photonics class. In third variant, the second pressure sensor based on address LC-FBG with two phase $pi$-shifts were utilized. The use of such type sensors will solve the problems of addressing the information received from specific wheelchair zones connected with right and left shoulder blades, buttocks and heels.

In this paper we present a radio frequency precision sensor on rectangular spirals with the opposite direction of winding. The sensor is purposed to control and measure the gap to a flat metal surface. The sensor model was created using CST Studio Suite software. Using this model, we obtained relation between the gap width and change of electrodynamic parameters of the sensor. A schematic diagram of the sensor's measuring generator based on a modification of the Colpitts LC-generator was developed, and its characteristics were obtained in the PSpice. This paper also indicates the advantages of using proposed sensor as a base for various devices and systems for monitoring, measurement and controlling of physical quantities and parameters of technological processes.

Methods and algorithms for embedding marked information with fractal properties to ensure the integrity and authenticity of raster images are considered. The features of using algebraic fractals as intermediate cover images, as well as secret keys that define places for embedding watermarks, are analyzed. Numerical examples show that the proposed methods increase the integrity and authenticity of bitmap images.

Modern infocommunication systems, combining the capabilities of computer technology and communication devices, almost always have a digital implementation using binary code. In this case, various code structures are used, which on the one hand provide high transmission efficiency of the initial messages, the required noise immunity and, as far as possible, simple practical implementation, which allows to achieve lower technical and financial costs, minimize delays, etc. Moreover, the question of how the solutions used differ from theoretically achievable potential boundaries is very important.
