The peculiarities of the use in a substation automation system of a digital combined current and voltage instrument transformer of a new type are investigated. The developed transformer has a voltage class of 110 kV and a measurement range of a current from 150–1200 A. The proposed intelligent electronic device is based on an electromagnetic current transformer and a capacitive voltage divider located on the high voltage side. The transmission of the measured instantaneous current and voltage values is carried out over a fiber optic cable. The construction of this transformer makes it possible to develop analogous equipment of information interaction for digital substations with other ranges of currents and voltages based on developed prototype. In existing digital combined instrument transformers, this combination of primary converters is not used. According to the information available, there is no serial production of such products, which indicates the possibility of obtaining a result capable of legal protection and further commercialization.

The paper describes the results of using the neuro-electrostimulation device for improving the attention and working memory characteristics. It was shown that the application of neuro-electrostimulation could be used as a corrective technique for subjects with low initial values of test parameters. Also it was found that some of the autonomic nervous system characteristics in particular VR and VLF spectral components of heart rate variability can be reflect the results of neuroelectrostimulation impact. In the processing of EEG, it was found that interhemispheric correlation links can also reflect the effect of neuroelectrostimulation.

Nowadays ultrasound studies of the heart, also called echocardiography (EchoCG), are widespread in modern cardiology. One of the most important steps in estimating the health of the heart is the tracking and segmentation of the left ventricular (LV) endocardial border from EchoCG, which is used for measuring the ejection fraction and assessing the regional wall motion [1]. The disadvantage of these methods is the necessity to apply image processing manually or in a semi-automatic mode, which requires special knowledge and skills. As a result, the issue of an automatic tracking and segmentation of the LV on EchoCG-images is an actual and practical problem. The capabilities of the fully trained model of the convolutional neural network Unet for automatic identification of the LV region are explored in this paper. The obtained accuracy of LV segmentation is up to 92.3%, which suggests the expediency of using Unet for automatic identification of the LV endocardial border on ultrasound images.

This work is dedicated neuromuscular interface, which is based on electrical impedance and surface electromyogram registered together. Active part of impedance is registered non-invasively using tetrapolar electrode system from a segment of the upper limb. Impedance signals are proportional to the movement's extent. In contrast to other techniques, this approach allows anthropomorphic bioelectric prosthesis control.

The dynamics of gas bubbles having different sizes was modeled for liquid media under the influence of ultrasound radiation in duplex research mode based on radiation pressure forces. Factors were considered and conditions were evaluated for occurrence of the “pseudo-flow” artifact in liquids with gas bubbles having different sizes under different radiation modes, intensity levels and work frequencies of ultrasound sensors for media with different viscoelastic behavior.

This paper investigates the phenomenon of an evaporation duct and the possibility of waves to propagate inside it. This phenomenon arises as a result of permittivity gradient in the space above the water surface. The model representing the evaporation duct as a multi-layer structure is suggested. The electromagnetic field intensity in every point of model is found by means of using Green's functions method. The paper presents both strict and approximated expressions. The simplest case of Hertz dipole in free space confirms the validity of proposed approach.
