For high-quality and fast rehabilitation after a severe injury of lower limbs, it is extremely necessary to adjust and gradually increase the load on the patient’s leg. This work is devoted to the development of a special device consisting of attachments for crutches that measure the load on the patient’s lower limb and transmit the measurement results to a smartphone to inform a doctor. It is possible to accelerate rehabilitation by rather exact regulation and gradual increase of loading on a sick leg. The procedure and scheme of rehabilitation is proposed. Smart nozzles on crutches have been proposed to monitor the load on a sore foot. Functionally, the device consists of a pair of nozzles for crutches. A strain gauge is integrated into each nozzle, which is connected to the wireless information transmission unit. In our case, we used a strain gauge DYHW-116 and a microcontroller MCU ESP32, designed to process and transmit information. The doctor determines the rehabilitation program according to the diagnosis and prescribes it to the patient, and the patient installs the application on the smartphone and enters his account (where there is already a rehabilitation program). The developed rehabilitation device includes a strain gauge, control board, screws and piston, which are housed in the housing. Printing parts can use ABS plastic. The patient uses nozzles on crutches, which determine the load on the patient’s leg according to the program, as well as captures their own feelings on the smartphone. The algorithm of the device allows you to get Statistics, which is sent to the doctor (nozzles – smartphone – doctor). The doctor can change the rehabilitation program if necessary. Rehabilitation techniques using this device show positive results. Further modernization of the device is aimed at making it cheaper and increasing the duration of using attachments, which will allow mass production of the device.

The issues of reducing the vibration caused by rotating rotors at the frequency of the first rotor harmonic (so-called rotor vibration) are among the most important in the design, manufacture and operation of almost all types of modern rotary machines. The washing machine as an object of study of the dynamics and reduction of vibration and noise is of particular interest due to the constant presence of randomly located and wandering imbalance of laundry in the drum and low requirements for accuracy of its manufacture and assembly of parts and assemblies. A mathematical model of oscillations of a multiconnected tank-drum system on elastic suspensions for the main types of machines and spin centrifuges with a horizontal axis of rotation is created. The model is developed in a linear formulation based on the Lagrange equation of the II kind for a washing machine. The accuracy and adequacy of the mathematical model was tested directly on the field object by measuring noise, vibration, forces in the supports and stress distribution in the individual elements and components of the machine in the entire range of drum speeds. Studies of the nature of system oscillations depending on the change in position and attachment points of elastic and damping elements were performed using simulation in the Simulink environment. As a result of research, the basic requirements for the layout of horizontal rotary machines of the drum type were experimentally confirmed: the center of mass of the tank must lie on the axis of rotation of the drum; the axis of rotation of the drum should be the main central axis of inertia of the tank; the center of mass of the tank must coincide with the center of mass of the loaded drum; the center of rigidity of the system of elastic supports must coincide with the center of gravity of the tank, and the main axes of rigidity – with the main central axes of inertia of the tank; the main axes of the constant viscous friction must coincide with the main central axes of inertia of the tank. The results of the theoretical study were applied to the problem of evaluating the efficiency of a liquid auto-balancing device for a proper squeezing machine depending on its dynamics.

The work is devoted to the analytical study of the energy parameters of a machine with a complex movement of the working capacity. In particular, analytical studies of the dynamic moment of resistance formed by the spatial movement of the moving parts of the machine were performed. It is established that when operating a machine with a complex movement of the working capacity, the moment of resistance on the drive shaft will change several times during one revolution and may have negative values. This phenomenon is due to the spatial movement of the tank and a sharp change in the position of the working environment relative to its walls. As a result of analytical research, an equation is obtained to determine the maximum value of the dynamic moment of resistance created by the spatial movement of the moving parts of the machine. It is established that the total maximum moment of resistance on the driving shaft of the machine is defined as the vector sum of the maximum moments of all forces acting on the loaded working medium to the tank and on the moving parts of the machine. Analytically, a general expression is obtained to determine the maximum power consumed by a machine with a complex movement of the working capacity on its drive shaft. The obtained research results can be used by design bureaus of relevant machine-building enterprises at the stage of designing rolling types of equipment.

Published: March 2022

In the practice of electrical and radio measurements, voltage measurement is a common operation. This determines the potential difference or voltage drop in the section of the electrical circuit (on its element). The purpose of measuring DC voltage is to determine its value and sign of polarity. When measuring AC voltage, any of its parameters can be determined (amplitude, mean, rms, rectified value or signal scope). The efforts of prominent scientists are aimed at improving the metrological and technical indicators of existing measuring instruments, in particular the development of new methods for correcting the characteristics of the transformation of the measuring channel, which is their main component. However, all these methods focus on converting the amplitude of the periodic signal into an equivalent parameter, followed by converting it into digital code. All this leads to additional conversion errors and requires additional hardware costs. Accordingly, the improvement of known methods for creating new converters of high-frequency periodic signals into code is a promising task at this stage of development of measuring technology. The paper points to noise sources and analyzes the influence of noise during the conversion of the amplitude of periodic signals into code by direct level quantization. It is established that for industrial tomography, the influence of external factors on the probing input signal is practically absent, because the processes of cavitation and chain reaction take place in a closed environment. It was found that the internal noise is related to the technical characteristics and features of each element of the structural diagram of the converter. Analytical expressions for estimating the influence of noise on the measurement process are presented. In the Matlab environment using the Simulink package, a model was developed for visual study of the influence of internal noise on the process of measuring the parameters of the amplitude of the periodic signal. According to the simulation results, the signal / noise dependence on the frequency of the input signal is obtained. Graphic materials are presented, which clearly demonstrate the influence of noise on the amplitude measurement process. It is established that the signal-to-noise ratio does not exceed 63 dB at frequencies of input sinusoidal signals up to 210 MHz at an amplitude value of 1B, which improves the technical performance of the converter.

Published: March 2022

The paper presents the results a study of methods for increasing the noise immunity of telecommunication channels with OFDM. The structure of the OFDM signal is investigated. The influence of the structure OFDM signals on the noise immunity of their transmission under the influence of the effect of intersymbol interference in a multipath channel is estimated. Recommendations are given on the choice of the OFDM signal form in order to counteract the influence of intersymbol interference by optimizing the duration of the pulse sequence. The behaviour of OFDM signals in the case of intersymbol interference in the AWGN and the Rayleigh channel is investigated. Recommendations for counteracting interference influence on the quality of communication are given. A comparison is made of the efficiency signal-code constructions based on concatenated codes in the case of their application in channels with OFDM. The article presents the results of the development models of effective coding in telecommunications with OFDM based on concatenated codes, taking into account the coding rate and the number of decoding iterations to ensure the specified noise immunity indicators. At the current stage of implementation of modern telecommunication technologies, the use of channel coding plays a key role in increasing the performance of channels that use OFDM. The main contribution of channel coding in combination with time and frequency interleaving is the formation of inter-bit communication in the data stream transmitted on separate carriers in the signal spectrum in such a way that the transmitted information data in the fading channel can be updated in the receiving equipment. In general, in this case, having frequency selectivity creates a certain advantage through frequency diversity. Thus, the presence of information about the state of the channel in the case of channel coding creates the prerequisites for obtaining a certain gain. Optimal in terms of speed and computational complexity, the selection of the scheme and algorithm for decoding the error-correcting code makes it possible to find a compromise in the design of concatenated circuits in channels with OFDM and ultimately obtain a satisfactory gain in performance.

THE INFLUENCE OF RIGIDNESS AND CONSTANCY ON THE ASSESSMENT OF WEAR RESISTANCE OF TEXTILE MATERIALS

Published: March 2022

The article examines the indicators of stiffness and immutability of cotonine-containing and mixed tissues of different fibrous composition. Their influence on hygienic properties of sewing clothes is analyzed. Fabrics for summer clothes should be stiff enough, as this affects the underwear space. At the same time, the presence of lignin in the bast fibers gives the cotton-containing fabrics increased rigidity, which negatively affects the draping of the fabrics and the sewing of products in silhouette. Stiffness, relief and heterogeneity of flax fiber gives mixed cotton-containing fabrics the optimal structure for the manufacture of clothing in the summer range. The permanence of the fabric affects the quality of the product, its service life and consumption costs. Among the important factors that affect the rate of indelibility of the fabric is the composition of raw materials and the type of finish. To increase the coefficient of immutability, fabrics with a content of more than 50% of cellulose fibers must be subjected to final finishing by mechanical or chemical means (low-folding or low-setting treatment). It is the rigidity of the material that affects its ability to resist bending. It is established that with increasing content in the composition of cotonine-containing fabrics of polyester and cotton fibers, the conditional stiffness decreases. It is proved that the stiffness of textile materials is influenced by their fibrous composition, structure, properties of fibers and threads, as well as the structure and processing of the material itself. The ability of a textile material to restore its original appearance depends on the elastic properties and elastic deformations with a rapid period of relaxation. Elongation at the time of breaking linen and hemp yarn does not exceed 3%, cotton – 6%. The share of elastic deformation in the total elongation of the fibers is insignificant. Therefore, products made of natural cellulose fabrics are not resistant to wrinkling. The addition of polyester fibers increases the elasticity of tissues and immutability. The reasons for the increase in the coefficient of immutability are: fabric shrinkage after the first cycles of washing, accompanied by an increase in the linear density of the fabric; reducing the degree of polymerization of cellulose, and, as a consequence, the destruction of cellulose fibers and leaching from the surface of the textile material.

The considered actual problem of controlling access to Internet resources has an important applied value: blocking access to illegal, extremist, antisocial information, preventing the disclosure of confidential information via the Internet, etc. For the development of a wide range of enterprises, the methods of machine technology have been developed. One of the most frequently victorious and effective methods for the classification of hedgehog traffic is the Random Forest, an ensemble method, which is a kind of tree path to inspire a multitude of virgins. To assess the effectiveness of the Random Forest algorithm in the classification of network traffic by types of application protocols operating on the Internet, the collection of network traffic was performed. Applications that generate packets related to different application layer protocols were studied: BitTorrent, DNS, HTTP, SSL, Skype, Steam. After selection of information features and preliminary data processing, training and test samples were formed, one of which contained background traffic. As a result of applying the Random Forest classification algorithm to the obtained data, estimates of the efficiency of this algorithm in the presence and absence of background network traffic were found. The presence of background traffic belonging to classes that did not participate in the training of the algorithm significantly impairs the accuracy of classification. It is shown that the number of attributes for traffic classification is not as important as the choice of classification algorithms. The results of the classification at the testing stage showed that the machine learning algorithms using the “decision trees” Random Forest and C4.5 are best suited for classification with a large number of classes. Classification accuracy indicators using AdaBoost and Bagging suggest that in most cases, combining multiple classifiers into an ensemble and making a decision based on “voting” can improve the results of the classification. To achieve classification accuracy, it is sufficient to calculate the classification attributes for a sample containing 5 …. 10 consecutive packets. Accuracy can be improved to 99% and higher if the statistics were calculated on the basis of 35 consecutive packets.

In the world and in Ukraine, the quinoa market is growing rapidly due to its extremely beneficial properties for the body. Quinoa is one of the few gluten-free crops with a high content of easily soluble proteins, which provides the possibility of making special foods for children, people who play sports, vegetarians and diabetics. Quinoa grain contains a lot of protein: from 16.2% to 20%, the amino acid composition of the protein is very balanced, quinoa grain also contains carbohydrates, fats high in lecithic acid, fiber, minerals and vitamins of group B. The dynamics of sown areas and quinoa production in the world. The work is devoted to the organization of the operation of purification of quinoa grain, which is an important stage of its post-harvest processing. Any processing of grain is associated with its purification from impurities. The presence of impurities negatively affects the efficiency of grain storage and its technological features, which leads to a decrease in yield and quality of processed products. Therefore, cleaning operations occupy a central place in the post-harvest processing of grain. We have determined the geometric dimensions and calculated the basic geometric parameters of quinoa grain, which are the main indicators for the organization and conduct of the cleaning process. To identify the necessary working bodies and determine the optimal size of the holes for the separation of the mixture into fractions, the analysis of the variability of the grain size of the main crop and the size of the released impurity. Based on these data, a correlation table is constructed. Analysis of the correlation table shows that for effective cleaning of quinoa grain it is necessary to use sieves with a diameter of 3… 3.5 mm to remove large impurities and sieves 1.0×20, with a diameter of 1.6 and 1.8 mm. Based on the data of the correlation table, a fractional scheme of quinoa grain purification was developed, with the appropriate shapes and sizes of sieve holes. This scheme of purification of quinoa grain is effective and allows to isolate 93% of impurities.

This article describes and investigates the difference between a decentralized and a centralized information system. The efficiency of use and introduction of new technologies in production is studied. The construction of blockchain-based systems and their efficiency in solving the tasks are analyzed. Conclusions are formed about the tendency that the introduction of decentralization proves the need for digital management systems. At a time when the implementation of blockchain technology has greatly simplified the construction of new decentralized systems, which is a current trend in the world. The basis of blockchain technology is in a distributed information storage. It allows you to store important information simultaneously on many servers, and therefore keep them open and safe. For example, on the basis of this technology it is possible store both the history of customers’ bank transactions, voting results, and database of contracts, fingerprints or medical histories. And the information that stored simultaneously in many places, it is impossible to steal it, because in any case they can be restored from the original sources. As already mentioned, a blockchain, a block of transactions, is a structure for writing transaction groups. Transactions are carried out only when it is considered confirmed. It is reliable and convenient when it comes to making payments or the transfer of confidential data. So that the transaction is considered confirmed, its format and signatures must be verified. After that, the group transactions are recorded in a special block. In these blocks, all data is fast to verify. And in each subsequent information about the previous is stored. For example, in transactions on cryptocurrencies, the chain contains blocks information about all actions ever performed with bitcoins. The block includes a header and a list of transactions. The title of the block has its own hash, previous block hash, transaction hash and other additional official information. The first thing that is specified in the transaction block is getting a commission that will be as a reward, so the user who actually and will create this block. For transactions in the block tree hashing was used.

Authors:   Khmelnytskyi National University, STARIY A.
Published: March 2022

Experimental stands of vibrating machines for cleaning and washing have been developed. An original membrane sensor and an electronic oscilloscope were used to measure the pulsating pressure of the jet. For the washing process, a method was used to create a gas-liquid pulsating jet of liquid in the pulsation chamber of the vibrating machine by oscillating the elastic membrane with disks. To increase the pressure of the jet during the cleaning process in the vibrating machine, it was proposed to connect the pulsation chamber and the cleaning tank with a non-return valve of the membrane type. To confirm the nature of the physical process of the mechanism of mechanical interaction of the liquid jet with contamination during washing, comparative studies of different washing methods were conducted; ultrasonic, jet and jet-pulsating gas-liquid washing. As a result of experimental studies it was found that the use of a diaphragm check valve in the drive of a vibrating cleaning machine allows to increase the maximum pressure of the immersed pulsating fluid jet by 0.045 MPa at oscillation frequencies from 14 to 18 Hz, which allows to increase productivity. It is established that the rational range of oscillation frequencies of the vibrating drive of the machine is in the range from 14 Hz to 16 Hz and it is recommended to use the oscillation amplitude of the vibrating drive 2 mm at a ratio of nozzle diameter to chamber diameter 1:10. Studies of model contamination washing confirmed the main theoretical assumptions on the mechanical nature of the interaction of detergent with contamination and showed the effectiveness of the method of washing with cavitation bubbles obtained by vibrating washing machine and the effectiveness of pulsating jet cleaning of solid particles or metals.

The work is devoted to the experimental determination of the energy parameters of a machine with a complex movement of the working capacity. An experimental installation of a galvanizing machine has been developed, in which the working capacity performs a complex spatial movement, where it is possible to vary in the required range by two factors of influence. Experimental studies of the moment of resistance and power consumed on the drive shaft of such a machine during its operation with a loaded working array to the tank using a digital two-channel USB-oscilloscope VM-8020. On the basis of a complete factorial experiment, the regression equation in natural quantities is obtained. The regression equation describes the dependence of the maximum power consumed by the machine on the drive shaft on the mass of the bulk medium and the angular velocity of the drive shaft. It is established that the power of the machine consumed on its drive shaft increases with increasing mass of bulk medium, which is loaded into the working tank, as well as with increasing angular velocity of the driving shaft of the machine. The previously obtained analytical dependences were checked experimentally and their adequacy was confirmed.

Introduction. The paper addresses the issue of insufficient readiness of teachers to nurture the qualities of a family man in preschool children in the communicative activity. The influence of a teacher on the development of these qualities and author’s approaches to the issue, which consider the necessary psychological and pedagogical conditions, are described. The study proves that it is necessary to work with teachers through various forms of activity that contribute to an increase in their readiness to bring up the qualities of a family man in pre- school children. Materials and methods. A questionnaire for teachers was employed to reveal the degree of readiness of the teachers in a preschool educational organization to develop the qualities of a family man in children: ideas about the upbringing of the family man in preschool children and awareness of the need to accomplish the objectives of this area of education (cognitive, motivational and value components). Monitoring of joint activities of teachers with children and interaction with parents allowed us to determine how teachers fulfill their capabilities (motivational, value, and behavioral components). Results. Analysis of the data obtained has indicated that most teachers have a low level of readiness to educate the qualities of a family man in preschool children. They do not consider it necessary to focus the attention of preschool children on family values. They know superficially about the qualities of a family man and can organize only elementary games for the development of these qualities. The teachers involved in the study do not realize their role in cultivating the qualities of a family man in preschool children. Conclusion. The study has determined the need to organize work with teachers to increase their competence in developing the qualities of a family man in preschool children. Analysis of the data has helped us to identify what knowledge is insufficient, what difficulties teachers face, and what exactly is worth working on. It is important to interest teachers; justify the relevance of the issue of developing the qualities of a family man; discuss forms, methods, and means for organizing the educational process aimed at cultivating qualities of a family man in preschool children; and provide methodological assistance to teachers through various forms of work that contribute to boosting the degree of readiness to educate the qualities of a family man in preschool children.

Introduction. The paper addresses the issues of the development of professional education of police officers in post-revolutionary Eastern Siberia in the 1920s. The archival documents were used to study forms and methods of professional training of young officers of workers and peasants’ police. The main of them were school training of the reserve and practical training of the officers in off-duty and on-duty hours. The study also focused on the issues that interfered with the professional training of officers and, eventually, did not allow the single system for the policemen training to be established. The objective of the study is to examine the issue of creating a system of training police personnel in the 1920s, highlight the activities of the administrative department intended to organize the professional training of police officers for the East Siberian region at a difficult time for the country, and the problems that arose. Materials and methods. The study employed synthesis methods, comparative analysis of historical sources, historical-system method, and the principle of historicism. Results of the study. The activities of the police of Eastern Siberia, which were aimed at the professional training of law enforcement officers, were investigated. The post-war Eastern Siberia faced a lack of personnel for the police since tsarist police were defeated, and the class approach to the personnel selection led to the situation where the policemen from workers and peasants were often poorly literate or illiterate. Therefore, there was an urgent need to establish a professional training system for police officers. Attempts were made to create this system, but they were unsuccessful in the 1920s. This activity, however, made it possible to lay a foundation for the establishment of such a system in the future.

Assessment of psychological mechanisms of socialization may entail identifying characteristics of social recognition claims in mentally-retarded adolescents. With this in mind, one can build psychological support for such adolescents. This paper presents findings of a study on specific features of social recognition claim as a component of assessing the psychological mechanisms of socialization in 13-15-year-old mentally-retarded adolescents. Of interest are not only the social claims of students with mild intellectual disabilities but also their understanding of how their claims are assessed by their close ones (friends, parents, and teachers). This paper presents empirical data on specific features of social recognition claims in mentally-retarded adolescents based on an interview and a modified “How am I evaluated” method. The sample of subjects was verified by assessing the subjects’ level of intellectual development using the Wechsler Intelligence Scale for Children. Adolescents with normal development were a control group. The findings of the study underwent qualitative and quantitative analysis. Significant differences (according to the Student’s t-test) were observed between adolescents in the target and control groups in terms of the level of social recognition claims and some individual parameters of the techniques applied. Pearson correlation analysis revealed a correlation between the level of intellectual development in the subjects and their level of social recognition claims. The higher the verbal intelligence score, the more appropriate the social recognition claims of adolescents are. The findings led to the conclusion that the level of social recognition claims in mentally-retarded adolescents is inadequate compared to that of their normally developing peers. This testifies to insufficient implementation of the reflexive mechanism of socialization. This kind of data can be instrumental in specifying the scope of psycho-correctional work with mentally-retarded adolescents.

This study contributes to the analysis of the Environmental Kuznets hypothesis (EKC) for 31 industrialized countries during 1980-2019 using long-term static and dynamic panel data methods. According to Pesaran's CD tests, the CSD issue is present in all variables. The EKC model had a long-run relationship, according to the results of the second-generation Pesaran CIPS unit roots and Westerlund tests. The estimation results of the static model (MG) and dynamic models (CS-DL and CS-ARDL) reached the same conclusion as the reliability of the EKC hypothesis, implying that environmental pollution and economic growth are linked in an inverted N-letter shape.
