Research of fault-tolerant control system of the formation process of carbon products
Authors: Zhuchenko Liudmyla
Published: July 2022

The production of carbon products is largely resource- and energy-intensive. That is why increasing the efficiency of this production is an urgent scientific and practical task, especially in modern conditions of constant growth of energy costs. An effective way to solve this problem is to create a modern process control system, taking into account the possible failures of system elements.

The practice of operating hydraulic presses in carbon graphite production, the control valve of the hydraulic press sometimes fails or works with errors. That is why this paper considers the stage of loading the process of forming carbon products in terms of building a fault-tolerant pressing speed control system.

The article investigates the fault-tolerant control system of carbon products, which is synthesized on the basis of traditional fault-tolerant systems for non-cyclic processes and control systems with iterative learning, which have demonstrated their effectiveness in control technological processes of cyclical nature. A method using linear matrix inequalities has been developed for optimal adjustment of control system parameters.

Based on the combination of control with iterative learning and control that takes into account the failures of regulators, built a control system for the formation of carbon products, which takes into account both the cyclical nature of the technological process and possible failures of regulators. The research of the effectiveness of the control system by comparing its work with traditional fault-tolerant systems and control systems with iterative learning in the event of faults and disturbances of various kinds showed that the proposed system improves control quality not only over time during each cycle, but also from cycle to cycle.

Further research should be aimed at the practical application of the proposed control system for different technological processes in different types of failures of regulatory bodies and the action of disturbances of different nature.

Introduction. The coronavirus disease 2019 (COеVID-19) caused by the SARS-CoV-2 virus led to the global pandemic, and by the beginning of August 2021, more than six million people fell ill in Russia. The study of the interaction between the SARS-CoV-2 virus and the cardiovascular system has great importance for the effective treatment of patients with this disease. Aim. The aim of the study was to identify the frequency of cardiovascular complications, based on the analysis of the patient’s medical histories with viral pneumonia caused by SARS-CoV-2 virus. And to compare the results obtained with the data of literary sources and justify their pathogenetic occurrence. Material and methods. 70 medical histories of patients with viral pneumonia caused by the SARS-CoV-2 virus who were admitted to the temporary infectious diseases hospital in Kazan were analyzed. The comorbidity, routine methods of laboratory (Complete blood count, qualitative and quantitative troponin test), and instrumental (ECG, Echo) diagnostics were studied. Descriptive statistics were calculated: median and interquartile range, categorical variables were presented in quantity and percentage. An unpaired t-test was used for the analysis of statistical significance. The critical value was assumed to be p≤0.05. Literature in eLIBRARY.ru, PubMed, GoogleScholar, Web of Science in recent years, mainly in 2020-2021, were analyzed. Results and discussion. Among the comorbidity: hypertension – in 31 (44%) patients, chronic heart failure – in 14 (20%) patients, coronary heart disease – in 10 (14.2%), diabetes mellitus – in 8 (11.4%), and 16 (22%) patients suffered from obesity. The most frequent complications were regurgitation on the valves (57,14%), cardiac arrhythmias (35,7%), of which supraventricular arrhythmias were the most common. There was no dependence of the increased level of Tr I on the degree of respiratory failure. Among patients with elevated Tr I levels, a chronological association with a previous infection with specific symptoms was revealed in all patients with high reliability of the presence of myocarditis in 12 (17,14%) patients. Conclusion. COVID-19 affects not only the respiratory system but also has a significant impact on the cardiovascular system because of the patient's immune response and the probable cytopathic effect of the virus.

DETERMINATION OF THE KINEMATIC LEAD/LAG RATIO OF TRACTOR WHEEL DRIVES TAKING INTO ACCOUNT TIRE INDICATORS
Authors: Rebrov Oleksii , Kalchenko Boris , Rebrova Olena
Published: July 2022

An analysis of the formation of the value of the kinematic lead/lag ratio of the tractor wheel drives is presented, taking into account the indicators of tractor agricultural tires. It is shown that the kinematic lead/lag ratio is formed as a result of the total influence of the internal gear ratio of the transmission and the values of the rolling circumference of the tires of the front and rear drive axles. It has been established that the actual values of the rolling circumference within tire groups, according to the rolling circumference index (RCI), have wide ranges of values. This can cause a wider range of kinematic lead/lag ratio variation of the front drive wheels, and in some cases even power circulation. For tires with a rolling circumference approaching the upper or lower limit of the interval within the rolling circumference index, as well as equipping the tractor with such tires, with an disadvantageous combination of the rolling circumference of the front and rear tires, the kinematic lead/lag ratio will go beyond the interval 1.01...1.05 which is recommended. It is shown that the kinematic lead/lag ratio can be either 0.982 or 1.074. Since even the use of the difference between the rolling indexes of the rear and front tires necessary for a particular tractor does not guarantee the recommended value of the lead of the front tires, it is imperative to determine it by calculation and check it experimentally in operation
RESEARCH OF OSCILLATIONS OF A TRACTOR DRIVING CLASS 3kN AND WAYS TO IMPROVE ITS RIDE SMOOTHNESS WITH REDUCING SPRING TENSION

Published: July 2022

In order to improve the smoothness of the course of the T-150K tractors, the possibilities of changing the main parameters of the suspension system and its influence on the intensity of low-frequency oscillations of the machine were considered. The stiffness and drag coefficient of the front suspension, as well as the base of the machine, were subjected to changes, and the range of variation was limited by the possibility of implementing the parameters without rearranging the units and changing the traction characteristics of the machine. As criteria for evaluating the smoothness of the ride, the values of the transfer function of the movements of various points of the frame, seat and root-mean-square accelerations during the movement of the tractor along natural irregularities were taken.

Based on the results of these studies, it was found that an increase in the tractor base by 10% has an insignificant and contradictory effect on the root-mean-square accelerations of the frame point over the rear axle over the entire range of design speeds from 2.5 to 7 m/s, and acceleration over the front axle and on the seat - up to a speed of 5 m/s. With a further increase in speed to 7 m/s (25 km/h), an increase in the tractor base by 10% reduces frame acceleration over the front axle by 15%, and on the seat by 20%. In addition, 11-leaf springs (when removing the 5th and 7th sheets), installed in the suspension with tractor hydraulic shock absorbers with optimal parameters, created on the basis of automobile shock absorbers of the MAZ-500E type, have smaller dynamic deflections during compression, than 13-leaf springs (suspension without hydraulic shock absorbers). According to this, the dynamic load on the 11-leaf spring, compared to the serial suspension, is reduced by 51% when the KhTZ-150K tractor is moving along a dirt road and by 30% when plowing the field across the furrows. Consequently, the stress on the sheets of an 11-leaf spring in the presence of shock absorbers in the tractor suspension will be less than that of a 13-leaf spring (without shock absorbers), which will ensure increased durability of the 11-leaf spring. In addition, the resource of the last spring should be increased by reducing the number of load cycles, since the suspension with these springs reduces the frequency of the tractor by 10% (according to experimental data).
PROSPECTS FOR THE DEVELOPMENT OF HYBRID CONTINUOUSLY VARIABLE HYDROSTATIC-MECHANICAL TRANSMISSION OF VEHICLES
Authors: Mittsel Mykola
Published: July 2022

The paper considers ways to increase the efficiency of two-stream hydrovolume-mechanical transmissions (GOMT) of vehicles through the rational choice of transmission mode and the introduction into the design of the recovery system of circulating parasitic power of the closed circuit. The proposed direction of development of two-stream GOMT type with differential "output" aims to expand the range of operating speeds where the transmission efficiency is high, in particular in the area of ​​low "creeping" speeds. Global trends to increase the efficiency of transmissions and reduce emissions of harmful substances into the atmosphere have led to the creation of hybrid and fully electric power plants. Hybrid transmissions, which include electric machines and internal combustion engines, are the most attractive from the point of view of operation, as they do not limit the distance of movement. In case of discharge of batteries, when there is no charging station, they will be powered by a standard engine. One of the ways to increase the technical and economic performance of wheeled and tracked agricultural tractors equipped with HOMT with an differential "output" is to coordinate the optimal modes of transmission with the main technological speeds at the design stage

Optimization of the internal shielding system in gas filled high voltage electric appliances with polymer insulation
Authors: Zhorniak Liudmyla , Afanasiev Alexej , Schus Vitaliy
Published: July 2022

In the article, the authors propose a technique for estimating the parameters of the electrical load for calculating the distribution of the electric field strength of a solid insulating structure of gas-filled high-voltage apparatus that have axial symmetry. This design is a support and insulating cover filled with SF6 gas as an internal insulating medium. This technique makes it possible to estimate the parameters of the electrical load (voltage and field strength) depending on the design features of the device and the shielding system that is used to equalize the electric field. The proposed method makes it possible to evaluate the effectiveness of the influence of the design parameters of the shielding system for gas-filled high-voltage equipment (instrument transformers, arresters, surge suppressors, etc.) when designing and improving individual design solutions. The calculation results are in good agreement with the data of experimental studies and statistical information obtained as a result of monitoring the operation of insulating structures, taking into account real operating conditions and the impact of external factors. The implementation of this technique makes it possible to take into account the influence of external factors and operational characteristics inherent in instrument transformers and surge arresters. In the proposed method, as an example, a supporting insulating cover is considered, which is during operation in the most unfavorable conditions, such as external pollution, moisture and their combination, overvoltage of various origins, etc. Theoretical conclusions are confirmed by the results of calculations on the example of the most mass-produced design of a gas-filled current transformer TOG-245 series. A more accurate determination of the effectiveness of the proposed method for predicting the parameters of the distribution of the field strength under the action of the shielding system can be achieved by carrying out an additional series of calculations and experimental tests of specific insulating structures. Thus, it was concluded that the obtained results can be used to assess the external insulation performance of both gas-filled instrument transformers and similar high-voltage switchgear equipment and transformer substations.
Releasers with electro-hydraulic retarders as an effective alternative for short circuit and overcurrent protection
Authors: Kalinchyk Vasyl , Pobigaylo Vitaliy , Borychenko Olena , Kuzovkin Sergii
Published: July 2022

It is known that circuit breakers (CBs) installed in distribution cabinets (DCs), better known as “enclosed circuit breakers”, depending on the execution, are designed for: - protection against emergency states of grids: overvoltage and short circuit (s/c) or voltage drop below the permissible level (circuit breakers installed on the grid do not always provide protection against voltage reduction); - protection of AC motors, as well as for combined installation with other electric devices (CBs can service by grid sections as well as separate motors if CBs are used to operate the wound-rotor motor or starting devices, they must include voltage drop protection); - to be used as disconnectors for supply and trunk networks. Overcurrent protection is done by a bimetallic plate, while an electromagnetic releaser provides s/c protection. The main features inherent in this technical solution of overcurrent protection include: - relative dependence on ambient temperature; - inability to quickly switch on again after the CB is triggered; - unstable time-current characteristics of the CB. National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute” and «E.NEXT Ukraine» offers an alternative solution for the design of CB protection elements, which is an integrated overcurrent and short circuit protection at the same time in the form of a releaser with an electro – hydraulic retarder. A releaser with an electro-hydraulic retarder triggers the СB actuator, which breaks the contact group of the CB when the current exceeding the set maximum permissible value (s/c or overcurrent) is passing through electrical equipment. The main part of this releaser is an electromagnet, whose coil is connected in series with working contacts in the circuit of the operating current.

La Enfermedad Renal Crónica [ERC] es un problema de salud pública a nivel mundial. En México, en el año 2018 murieron 13.845 personas por esta causa. El incremento en el riesgo de mortalidad está asociado a la falta de apego al tratamiento. En pacientes pediátricos, una parte importante del manejo de la enfermedad recae en el cuidador primario. El propósito de la presente investigación fue evaluar la eficacia de una intervención cognitivo conductual para mejorar la adhesión al tratamiento y la calidad de vida, así como promover recursos psicológicos en pacientes pediátricos con ERC en tratamiento de hemodiálisis y al mismo tiempo disminuir la carga en sus cuidadores primarios. El estudio empleó un diseño mixto, longitudinal, que incluyó pre-test, una intervención cognitivo conductual de ocho sesiones en el que se utilizó un manual, una evaluación post-test y un seguimiento a los dos meses. Participaron 5 pacientes pediátricos entre 12 y 17 años de edad y sus cuidadores primarios que asistían a un hospital público de la ciudad de Morelia, Michoacán, en México. Los resultados cuantitativos mostraron una mejora en la adhesión terapéutica, en la calidad de vida global y en los recursos psicológicos de los pacientes, así como una disminución de la carga en los cuidadores primarios. Los hallazgos cualitativos mostraron que los pacientes lograron entender su padecimiento, expresaron sus emociones respecto a la enfermedad y reconocieron el apoyo de su cuidador primario. Se concluye que el tratamiento cognitivo conductual es una propuesta de intervención eficaz para mejorar las variables de estudio.

El uso de las Tecnologías de la Información y la Comunicación (TIC) en edades tempranas es cada vez más generalizado. El objetivo de este trabajo fue aportar evidencias de validez y de fiabilidad de la adaptación al español de la Escala de Uso Problemático de Medios con Pantallas (Problematic Media Use Measure) y su versión corta (Problematic Media Use Measure Short Form). Ambas evalúan el uso problemático de los medios con pantalla en menores de 4 a 11 años, con la información proporcionada por sus progenitores. La evidencia de validez se basó en el análisis de su estructura interna y su relación con otras variables, y la estimación de su fiabilidad se basó en el modelo Omega de McDonald. La muestra consistió en 230 progenitores de alumnos de dos centros de educación infantil y primaria de la provincia de Huelva (España), con una edad media de 39.58 años (DE = 5.70). Los progenitores aportaron datos de 230 menores, con edades entre los 4 y los 11 años (M = 8.65; DT = 2.12). De estos, 111 eran niños (48.3%) y 116 niñas (50.4%), con tres participantes omitiendo el género. Los resultados, obtenidos mediante un Análisis Factorial Confirmatorio, muestran que ambas escalas se ajustan a un modelo unidimensional y cuentan con altos valores de confiabilidad (valor Omega de McDonald de .96 para la escala completa y de .90 para la reducida). Se encontró que los dispositivos más utilizados fueron TV, DVD y vídeos, y que su uso se correlacionó positiva y significativamente con la preocupación de los padres. Ambas escalas en su versión española se muestran como instrumentos útiles para evaluar el uso problemático de los medios con pantallas a partir del reporte de los padres

Este plano de aula tem como objetivo fazer análise da paisagem do local de vivência dos estudantes do sexto ano com o uso de geotecnologia, no caso o Google Earth, objetivando perceber as modificações ocorridas entre os anos de 2003 e 2021. O ensino de Geografia deve superar as metodologias tradicionais que focam na memorização e incluir metodologias que despertem a autonomia e o protagonismo. A abordagem do lugar do estudante o remete a ter um olhar espacial sua realidade, buscando ressignificar seu cotidiano.  A Geografia, enquanto componente curricular e tendo como objeto de estudo o espaço geográfico, deve oportunizar aos estudantes o contato e uso das geotecnologias disponíveis para observações e reflexões sobre o uso da superfície terrestre. Conclui-se que o uso de geotecnologia para analisar as modificações temporais na paisagem demonstrou-se eficiente, contribuindo na compreensão dos fenômenos e novos aprendizados aos estudantes.

There is very little knowledge on microplastic pollution in the Western Ghats (WG), a heritage site in southwest India. To address this, we have studied the seasonal variations of sedimentary microplastics (MPs) from River Sharavathi - a pristine river in the WG, southern India. We analysed the sedimentological and carbon content (organic and inorganic) of these sediments and explored their relationship with MPs. Finally, risk assessment indices such as the Pollution Load Index (PLI), Polymer Hazard Index (PHI), and the Potential Ecological Risk Index (PERI) were calculated to detect the levels of plastic pollution. The concentration of MPs ranged from 2.5 to 57.5 pieces/kg and 0 to 15 pieces/kg during the pre-monsoon and post-monsoon seasons, respectively. The dip in the MPs abundance during the post-monsoon season was due to the extremely high rainfall in the river basin during July-August 2019, which would have entrained the sedimentary MPs and transported them to the coast/Arabian Sea. Smaller MPs (0.3-1 mm) were more abundant than the larger MPs (1–5 mm), mainly due to the breakdown of sedimentary plastics by physical processes. Fragments, films, foams and fibres were the main categories of MPs and the main polymers were: polyethylene > polyethylene terephthalate > polypropylene. No significant relationship was observed between the sedimentological properties and microplastics, which may be due to the different physical properties of sediments and microplastics. The PLI, PHI, and PERI indices suggest different contamination levels in the river basin, and the district administration can use the data to mitigate plastic pollution in heritage sites.
A biologically inspired approach for recovering the trajectory of off-line handwriting
Authors: Senatore Rosa , Santoro Adolfo , Parziale Antonio , Marcelli Angelo
Published: July 2022

Background: Reconstructing the trajectory from the static image of handwritten ink traces is useful in many practical applications envisaging handwriting analysis and recognition from off-line data, as it allows to use methods, algorithms and tools that deal with on-line data, achieving better results than those achieved on off-line data.Methods: In this work we addressed the trajectory recovery by proposing an approach inspired by the processes involved in human learning of motor skills to perform voluntary and complex movements. As humans learn motor skills by a trial-and-error process driven by the performance and the consumption of metabolic energy, our approach generates a trajectory and estimates the consumption of metabolic energy needed to execute it, and in case it is deemed too energy demanding, a new one is generated and its energy consumption is evaluated. Eventually the one corresponding to the minimum energy consumption among the extant ones is selected as the actual one. Results and Conclusions: The effectiveness of the proposed approach has been quantitatively and extensively evaluated on a large and publicly available dataset, containing multi-stroke words. The experimental results show that our approach outperforms the existing ones in terms of Root Mean Square Error and Dynamic Time Warping distance between the recovered trajectories and the actual ones. Furthermore, an on-line recognition system provided with the trajectory recovered from off-line samples showed an overall reduction of about 1% with respect to the recognition rate achieved by the system when provided with on-line data.

Electron acceleration due to the beating of two linearly polarized lasers of finite spot size at an arbitrary angle in a vacuum has been investigated. The interference at certain angles due to these lasers with slightly different frequencies interacting at any arbitrary angle has been studied. Due to the constructive interference between these lasers, their resultant electric and magnetic field points out in a particular direction, where the electron is injected for effective trapping and noticeable acceleration has been observed. Sensitiveness of chirp parameters on electron acceleration have been observed. Along with this, a periodic frequency chirp plays a crucial role in the improved acceleration of electron. In this way, electron energy is enhanced more conveniently.

This paper proposes a rough surface micro-contact method to investigate the contact characteristics of the interface between the outer surface of in machine tool main spindle and the interference connection of the inner ring surface of a bearing. Based on the measured data of real rough surface, a contact model between the single micro-convex body and the rigid surface is established, and the variation rules of the micro-convex deformation and the normal contact stiffness on the whole contact interface are analyzed in the stages of elastic deformation, elastic-plastic deformation and full-plastic deformation. The relationship between the contact stiffness of the micro-convex body and the macro-overrun of the interface between the spindle rough elastic surface and the bearing rigid inner ring surface interference connection is modeled by the mathematical relationship between the macro-overrun and the separation distance between these surfaces. It is found that, throughout the contact process, different ranges the interference amount can cause different forms of deformation of the micro-convex body at the contact interface, and the contact stiffness grows nonlinearly with the increase of interference amount. Finally, the finite element results are used to verify that the contact stress between the rough surface micro-convex body and the rigid smooth surface on the unit contact area shows a nonlinear increase as the interference gradually rises, which indirectly proves the correctness of the derived model describing the relationship between the contact stiffness of the micro-convex body and the macroscopic interference the full contact domain , and provides theoretical support for the rational selection of assembly design parameters at multiple scales.
Digital Mindfulness Trainings and Cognitive Functions – A preregistered systematic review of neuropsychological findings

Published: July 2022

Traditional mindfulness interventions have been frequently reported to be effective in improving cognitive functions. In recent years, however, traditional programs are increasingly replaced by technology-enabled mindfulness interventions. The aim of the present systematic review (PROSPERO ID: CRD42021289480) was to evaluate the research evidence on their effects on cognitive functions. Empirical intervention studies in the realm of digital mindfulness trainings fulfilled the inclusion criteria, which led to 19 studies and 1,257 participants being included in this review among PubMed, Scopus, and Web of Knowledge. Results support previous assumptions on the potential of digital mindfulness trainings with the most robust effect on attention control, followed by executive regulation and memory, cognitive flexibility, and other cognitive functions. However, the number of studies that did not find significant changes at least equaled, if not exceeded, the number of studies that found increases. The heterogeneity of identified studies prompted us to discuss several aspects in order to help future development of digital applications.
