an intelligent defect recognition system based on artificial neural network (ANN) is proposed. A convolutional neural network (CNN) has been selected based on the analysis. To achieve this goal, the following has been carried out: creation of an image database for network training; network architecture development; implementation of a program in MATLAB. The study has been carried out for various objects of non-destructive testing. The result of the testing system work was assigning to one of the defects classes and determining whether there is a defect or not. A technique for automated visual non-destructive testing based on artificial neural network has been developed.

An engineering technique for the tolerance design of active RC filters using advanced OrCAD PSpice tools is considered. The implementation of the tolerance synthesis method based on sensitivity analysis is substantiated. The issues of the operability margin formation and the measuring of performance parameters, their sensitivity to variations in the element parameters are discussed. The variance balance allocation allows for significant differences in the availability of discrete resistors and capacitors with the required tolerances. Variations in the operational amplifier parameters are also taken into account.

The article analyzes industrial networking ecosystems that have added intelligence to manufacturing equipment, processes, and control. The features of the development of Functional Networking Components (FNC) are presented. FNC have the ability to receive and process information (the presence of a computer with network ports), have a physical nature (including hardware and software resources) and can affect the environment,. The structure of the FNC, which determines the function of these devices, and its main elements are considered. The article analyzes cybersecurity problems and ways to solve it. The use of digital matrices (FPGA) as part of the FNC hybrid calculator makes it possible to solve some security problems successfully. An example of the development and simulation of the FNC functional module, a combined generator of powerful ultrasonic vibrations, is considered. The network capabilities of FNC for switching and routing information packets are noted. FNC can be used as an element of a telecommunications network.

Wireless sensor network is an excellent tool for gathering data from various sensors scattered over the area. However, reliability requirements applied to the network nodes are generally higher. A variety of factors contributing to the reliability of the network should be taken into account. In the present study, the reliability indicators for both a typical network node and the WSN as a whole will be evaluated. The mathematical models for estimating mean down time, failure rate and availability factor will be constructed. The influence of external factors on the reliability indicators will be clarified. Throughout the entire calculation process, unique Russian software systems will be used. And finally the impact of both sensor nodes and base stations reliability indicators on the operability of the entire network will be estimated.

Measuring generators with a prescribed electrical power is a relatively new type of devices. Their application is especially promising in the field of medicine, electrochemistry, and a number of other areas where you have to deal with heat-dependent objects, whose parameters may change due to non-standardized electrical energy introduced into them during the measurement. Generators based on signal division have been fairly well researched, in contrast to structures based on signal multiplication. This article presents the study results of a prescribed electrical power generator based on the multiplication of signals and a voltage-controlled voltage source. The data obtained by computer simulation are consistent with the results of the generator circuit practical implementation. The generator can be implemented using only four IC’s and provides the maintaining full-scale error of a prescribed electric power less than 15% in the range of load resistance variation from 50 to 1000 kOhm.

To increase the efficiency of thermoelectric devices, nanostructured thermoelectric materials for operation in the temperature range from 170 to 1200 K having high values of thermoelectric figure of merit were obtained. Thermoelectric materials have the following maximum values of ZT: Bi2Te2.8Se0.2 – 1.15; Bi0.5Sb1.5Te3 – 1.17; Bi2Te2.4Se0.6 - 1.16; Bi0.4Sb1.6Te3 - 1.18; PbTe – 1.31; GeTe – 1.41; SiGe – 1.23 for n-type and 1.21 for p-type. Parameter ZT is determined for the operating temperature range of each material. Increase of the figure of merit for nanostructured TEMs in comparison with the usual structure is determined by the decrease of thermal conductivity by 10–15% due to the phonon heat transfer.In order to increase the efficiency of thermoelectric generators by increasing the temperature difference between hot and cold thermoelement junctions, multisection thermoelements are used. For such a thermoelement with operating temperatures up to 1200 K, the structures and technology of contact systems obtained by vacuum deposition of thin films have been proposed and justified. The influence of the preparation of thermoelectric material surface and the structure of contact systems on their thermal stability, contact resistance and mechanical strength has been established. Effective contact systems are proposed for the temperature range from 300 to 1200 K: Ni; Mo/Ni and Mo/Ta-W-N/Ni, having an adhesive strength of at least 16.0 MPa and a contact resistance of not more than 4.9•10-9 Ohm•m2.

The article discusses the modernization of a device that helps visually impaired people to detect obstacles such as "step up" and "step down".The article presents a structural diagram of a modernized device, an updated element base, a new design, as well as expanded functionality.Instead of two HCSR-04 ultrasonic sensors, two JSN-SR04T ultrasonic sensors with a transmitter and a receiver combined in one housing with a working distance of up to 4.5 m were used as sources of information about obstacles in the upgraded device. Sensor signal processing was now performed using the Arduino Nano platform. Signals about the presence of obstacles, their type and distance to them were output to one vibration motor. The upgraded device was powered not from one 9V battery, but from one high-capacity NCR18650B battery with a charging board.A smartphone can be connected to the upgraded device via a wireless communication module, on the screen of which programmed information about a person’s movements can be displayed. In addition, you can make some changes to the software settings using your smartphone.The structurally modernized device is made in the form of a conventional walking stick, and the replacement of the ultrasonic sensors with the JSN-SR04T made it possible to mark the sensors in the handle and the rubber tip of the cane, making their presence less noticeable to others. The weight of the finished device was 490 g with a cane height of 83 cm.Testing this device on a limited set of conditions showed the validity of the chosen research direction. During the experiments, such a drawback was found as the appearance of false alarms when moving in an apartment on the carpet when an obstacle of the "step down" type is detected. When walking on laminate and linoleum, there were no false positives.
