In this article, the control of a pilot pressure plant was developed by means of artificial neural networks, using the training and learning possibilities that these provide. The same control algorithms used in industrial plants can be applied in this pilot plant. With the implementation of this pilot pressure plant, a comparison was made between conventional control techniques and intelligent control in terms of efficiency and usefulness. This comparison was carried out by means of experimental data considering the results obtained with the conventional controller and the controller proposed by neural networks. A series of perturbations were performed once the system was in its steady state to obtain the response times of both control methods and determine the efficiency and advantages of intelligent control. The control was performed on the Arduino Mega board in serial communication with Matlab®(R2021b) to visualize the variables and thus observe the system behavior in real time.

In the scientific literature, there is a lot of discussion on approximate multipliers and circuits based on approximate 4-2 compressors. The designer who wants to employ an approximation 4-2 compressor is confronted with the challenge of choosing the proper topology due to the enormous number of options. A complete study and comparison of the roughly 4-2 compressors that have been suggested in the literature are presented here. One more compressor is shown, so that there are now twelve distinct approximate 4-2 compressors evaluated. The goal is to create logic gates that can be reversed. Quantum computing relies heavily on the reversibility of logical operations. This technology's gadgets run at very fast speeds and utilize very little power. Hardware description language (HDL) is used to create simple reversible logic gates. The Verilog implementation of the Wallace tree multiplier uses a simple half adder and a full adder. The reversible logic gates have been created, as well as a 4bit reversible adder, irreversible adder along multiplier has been developed. Layouts are designed using a variety of foundry technologies, and these methods are compared. We've reached the end of the road in terms of low-power dissipation. An 8x8 bit reversible multiplier circuit has been suggested and developed in this article. In terms of speed and complexity, the suggested reversible multiplier is superior to the current multipliers. In terms of the number of gates, garbage outputs, and constant inputs, it is superior to the current alternatives. The "HNG" 8x8 reversible gate was recently suggested by Haghparast and Navi. It is possible to use a reversible HNG gate as a reversible full adder when it is used alone. The reversible multiplier circuit in this study is built using HNG gates. Two 8-bit binary integers may be multiplied using the HNG gate in the proposed reversible multiplier circuit. A generalized version of the suggested reversible 8x8 multiplier circuit may be used for NxN bit multiplication as well.

This study aims to create a laboratory unit for induction heating and assess how possible it is to use local induction heating in solving problems related to biotechnology and medicine. This article contains a description of a method for non-contact local hyperthermal heating of biological tissues using inductive electromagnetic radiation. The method is based on the introduction of a composite material consisting of a polymer base and incorporated ferromagnetic particles into living tissues. The authors present a simplified mathematical model of physical processes occurring during the heating of a polymer sample-implant. The results of mathematical modeling are further used to approximate the data obtained in experiments on a specially built laboratory unit. The materials for building the applicator included a mixture of a plastic polymer and a hardener. The plastic polymer was modified by adding finely dispersed ferromagnetic particles and thoroughly mixed. Since the further use of the polymer applicator will occur in the field of biotechnology and medicine, the material for the manufacture of the applicator was Speedex putty silicone impression mass. The authors have calculated the physical parameters of the simplest model of the heated applicator. The nature of the dependence of the efficiency of induction heat release has been established. An increase in the efficiency of induction heating with an increase in the size of electrically conductive particles has been proven. Another series of experiments has been organized with double power consumption. The authors see the prospect of further development of studies in the chosen area in the development and creation of an automated control system and long-term maintenance of the temperature of heated samples at the target level. To do this, it is necessary to compare various methods for controlling the thermal power: control of the duty cycle of the master oscillator pulses, frequency shift near the resonant frequency, periodic on/off switching of the master oscillator, etc. Besides, it is necessary to develop a technique and technology for monitoring the uniformity of the sample temperature, which is especially important due to the complexity of using conductors in the induction heating zone. Finally, an important task for further studies is the development of different inductors for different applications. The authors assume that an open external inductor with a ferrite core may become the most probable model.

With the growth in the number of applications deployed in cloud app repositories and the increase in the number of users consuming them, usability has become a differentiating factor that promotes the competitiveness of software companies and user productivity. One of the usability tests that focuses on evaluating the layout and/or distribution of the elements in the graphic interface is the mouse tracking test, which has as a challenge the analysis of the mouse trace obtained in the test. In this paper we propose as a contribution the application of unsupervised learning techniques and specifically the use of clustering techniques from the K-Means algorithm in the analysis of the mouse trace obtained in a usability test under the mouse tracking approach. In this way, from the images with the mouse traces generated in these tests, the distribution of the mouse trace points around a set of centroids is obtained, with the purpose of determining the area of the screen in which there was more interaction in the test by the user and in order to make decisions on the layout and distribution of the interface components.

Silent blocks are one of the most common and characteristic mates in transport technology, and, in particular, in the design of shock absorbers for car suspensions. The defect such as a “silent block rupture” is characteristed for the rear shock absorbers in operation, Moreover, the silent block often fails much earlier than the shock absorber itself. The shock absorbers restoration by replacement with new silent blocks of standard design does not solve the problem of unsatisfactory durability. The authors consider that the reserve for increasing the durability of shock absorbers is to improve the restoration of silent blocks due to original technical solutions for repair kits. Original technical solution for the silent block repair kits is using a bearing with a movable conical spring insert in it. The design parameters of such an innovative repair kit were previously theoretically substantiated in the authors' works. The silent block repair kit consists of a modified standard silent block and additional elements - a steel sleeve and a conical spring insert. It is presented the developed technological process of manufacturing a repair kit. The validity of the theoretical prerequisites for the development of a repair kit for the silent block of the shock absorber of a vehicle containing a bearing with a tapered spring insert is confirmed by the results of experimental studies using high-precision measuring and control tools, as well as observations under operational conditions. The scientifically substantiated technical and technological development presented in this research is essential for increasing the efficiency of road transport operation by substantiating the principle and developing a technology for restoring the health of vehicle suspension joints using repair kits with movable spring inserts. Summarizing the research results and observations, we can conclude that the developed innovative silent block repair kit has the following important practical advantages; 1. The durability of the node is increased in 1.5 - 2 times due to the presence of such phenomena that are absent in the known designs of bearings, such as the “ratchet effect”, “the effect of oil and thread” and “the effect of wearlessness”; 2. The costs are reduced for the manufacture and assembly of the repair kit by reducing the requirements for the accuracy of the working surfaces of the parts.
