Authors:   Universitas Padjadjaran, Indonesia, Citraresmana Elvi , . Erlina , Sidiq Inu Isnaeni
Published: April 2022

This article discusses the lexical and semantic representation through the collocation that appeared in the Coronavirus Corpus. This research investigates the frequent collocates that appeared together with the node word Corona and find out how those collocates construct the meaning through the linguistic system and conceptual system as they are involved in lexical representation. This research offers a new insight into teaching language using Lexical Concepts and Cognitive Models (Evans, 2009). The data collected are from the Coronavirus corpus by using the corpus-based method. The strength of the keywords and collocate is measured by using Mutual Information (MI). The MI was set in 5; therefore, three lexemes resulted, i.e., cases, patients, and outbreak. The data were analyzed using the lexical concept and cognitive model proposed by Evans (2009). The research results, in general, reveal that the information is coming from the “authorized institution” and “government’s representative”; it needs “the official approval or agreement” before publishing to the media, and in the passive form, it describes the foregrounded information and agentless informational assertion. Therefore, the information should be accurate and firm. However, another lexical concept reveals that the information is terrorizing and terrifying; the educated and trained person should also conduct the treatment.
The Skills of Turkish Teacher Candidates to Use the Functions of Language in the Narrative Texts
Authors:   Recep Tayyip Erdoğan University, Turkey, Çelikpazu Esra Ekinci
Published: April 2022

Communication is an important part of our life. The realization of the communication and the achievement of its purpose is possible by understanding the function of the linguistic units used by the speaker or the text producer. In this case, the communication functions of the language, which is an important part of communication, must be known/recognised. Linguists, sociologists, and psychologists have taken different approaches to classify the functions of language. One of these approaches is the classification made by Roman Jakobson from the Prague linguistics school. Jakobson considers exchanging information between addresser and addressee as an essential element in communication. He also states that language has six functions: expressiveness, referent, call, relationship, metalanguage function and artistic function. In this research, the narrative texts of Turkish teacher candidates were examined in terms of the functions of the language by using Jakobson's approach. The model of the research is case study as it covers both the collection of field-based data, and the process is related to evaluations. Data were collected through documents during the process. The documents of the research are the narrative texts prepared by the 2nd year Turkish Language Teaching students studying at a state university within the scope of the linguistics course. The results of the study showed that there is a significant difference between the pre-service teachers' use of language functions in the narrative texts they wrote before learning Roman Jakobson's classification of language functions and the narrative texts they wrote after learning.
Exploring Conceptions of Creativity and Latinidad in Environmental Education Through the Lens of Culturally Sustaining Pedagogy
Authors: Román Diego , Arias Juan Miguel , Sedlacek Quentin C. , Pérez Greses
Published: April 2022

Environmental education seeks to foster meaningful connections to local and global environments through creative nature experiences. Responding to critiques of historical inequities, practitioners are prioritizing equitable access for historically marginalized youth, particularly from Black, Indigenous, and Latinx communities; this identity-centered prioritization, while essential, generates questions of normativity, diversity, relevance, and engagement within identity groups. Drawing on creativity as meaningful person-world encounters characterized by pluriperspective, future-oriented, nonlinear, and open-ended qualities, this chapter uses culturally sustaining pedagogy to explore how environmental education studies (a) operationalize Latinidad and associated constructs, (b) enact creative experiences in environmental education, and (c) qualify the roles of Latinx communities in shaping these creative experiences. We review studies of environmental education with Latinx youth in the United States that explicitly employ culturally sustaining approaches to engage these communities. We bring together these frameworks as a strategy to move beyond discrete notions of Latinidad in environmental education and toward nuanced conceptions of what it means to acknowledge and cultivate environmental literacies in these diverse comunidades.
The Production of Blue and White Porcelain with Bi-Shaped Bottom at the End of the Ming Dynasty and Its Influence on White Porcelain of Royal Kiln in the 17th Century of Joseon Dynasty
Authors: Park JungMin
Published: April 2022

The shape and size of the bowl vary depending on the region and the times. A bowl used every day does not change its shape significantly. Over time, the detailed shape and size of the bowl gradually change. The shape of the bowl may change due to various factors, such as changing the climate environment, growing social scale, and changing the composition of the community's changes. However, it is difficult to clearly analyze the cause and time of the difference in the shape of the bowl that changes according to gradual cultural changes. On the other hand, if there is a bowl of unusual shape and pattern, the cause and change of its appearance can be directly inferred. The white porcelain with bi-shaped bottom made in Joseon and Japan, including China in the 17th century, is a prominent formative element in the ceramic culture of the three East Asian countries. Since the production period is limited and the appearance is special, it is also used as a material to determine the production period. In fact, bi-shaped bottom is recognized as one of the important characteristics of white porcelain in the 17th century in the study of Joseon ceramic history. Due to their preference for antiques, which were popular in the late Ming Dynasty, the characteristics of the previous period’s Ming Royal kiln ceramics were reflected in the products of commercial kiln’s white porcelain in China at that time. The contact between Joseon and China, which was caused by the Japanese Invasion of Joseon in 1592 and the Manchu war of 1636, allowed the Joseon royal family and the capital city to use various Chinese porcelain, including blue and white porcelain with bi-shaped bottom. After the Japanese Invasion of Korea, Joseon gave sincere services to the Ming court, diplomats and made the form Chinese. Later, in the 17th century, Joseon Royal kiln produced white porcelain ref lecting the characteristics of Chinese vessels, and it can be understood that white porcelain with bi-shaped bottom also appeared in this trend.

Indonesia dengan jumlah penduduk muslim yang besar, sehingga memiliki potensi zakat yang besar (Jurnal et al., n.d.). Namun dalam pandangan Islam, kemiskinan terjadi karena gagalnya umat Islammengelola harta (T W Putra & Naufal, 2021). Islam mengajarkan kita bahwa kekayaan tidak boleh mengalir hanya diantara orang kaya. Orang kaya memiliki kewajiban untuk menguntungkan orang lain, sehingga mereka tidak bisa mengabaikan saudara-saudara mereka yang miskin. Kemiskinan sangat berbahaya bagi kehidupan karena mempengaruhi keyakinan, moral, perilaku, hati nurani, pikiran serta mendorong orang untuk berbuat dosa(Trisno Wardy Putra, 2021).
Maars, tuff rings, and tuff cones at the Manyara rift escarpment, Tanzania.

Published: April 2022

About 350 maar craters, tuff rings, and tuff cones are spread along the Manyara rift escarpment, and clustered around the Hanang and Kwahara volcanoes in North Tanzania. They lie in the East African Rift, an active extensional setting, where the magma composition is moderately to highly alkaline and carbonate-rich. We present newly-collected depositional characteristic observations, grain size distributions, and texture analyses of tephra deposits from selected maars, tuff rings and tuff cones of alkaline composition in Manyara to illustrate the range of the associated eruption dynamics and eruptive styles. We observed deposits with some evidence for water-magma interaction and deposits without. We attribute this range to varying magma ascent conditions and water availability along intrusive paths. Magma is guided by fractures allowing it to rise fast and to exsolve gas only near the surface. If water was available within a fracture, a moderate phreatomagmatic eruption was triggered and formed a shallow maar. In a dry fracture, the magma was fragmented by gas exsolution near the surface resulting in a tuff ring or a tuff cone. Several tephra deposits show similarities with kimberlite deposits, notably so the spherical and ellipsoidal shape of the juvenile lapilli and the presence of cannonball bombs.
What’s love got to do with it? Understanding barriers to care workers’ labor organizing
Authors: Flores-Robles Grace , Gantman Ana P.
Published: April 2022

The United States is facing a shortage of care workers – a workforce that is comprised mostly of women and is seen as feminized labor. One way to attract more care workers is to improve their working conditions. Yet, when care workers organize, they meet opposition in the mainstream press. In this research, we explored whether care workers face opposition and why. In Studies 1-3 (N = 353), we found that tensions between love and money in care work and endorsement of social roles were both negatively associated with support for care workers’ labor organizing. In Study 4 (N = 110), we again found that tensions of love and money were negatively related to support, but found no difference in care vs. non-care occupations. In Study 5 (N = 339), we actually found greater support for care (vs. non-care) workers on strike, but that beliefs in social roles still predicted opposition. Overall, we found overwhelming support for care workers who organize, despite media narratives against them. However, perceived tensions of love and money in care work and endorsement of social roles consistently predicted opposition. We discuss these implications for occupational segregation, the gender pay gap, and the devaluation of care.

Published: April 2022

O policiamento executado por empresas de segurança privada é uma das características dos sistemas de controle social das sociedades modernas. O Brasil não foge à regra e possui um expressivo setor de segurança privada em contínuo crescimento. Quando em suas atividades de policiamento, os agentes privados possuem poderes que, embora não sejam os mesmos disponíveis aos policiais, são igualmente eficientes e potencialmente ameaçadores aos direitos e liberdades individuais dos cidadãos expostos a eles. Diante desta realidade, é fundamental compreender quais os fundamentos e limites desses poderes. Este trabalho visa contribuir para o entendimento de tais poderes, mais especificamente o poder de revista dos agentes de segurança privada, através de análise quali-quantitativa de uma amostra aleatória de decisões judiciais coletadas nos tribunais de São Paulo e Paraná, julgadas entre os anos de 2010 e 2012.

Published: April 2022

The present work proposes a practical approach to determining the main types of algorithms, depending on their effectiveness in the appearance of the software code. Examples of analysis of the software code for computational complexity are given in the order of reducing the efficiency supplied as (in asymptotic designations): O(1), O(LogN), O(N), O(NlogN), O(N2), O(N2), O(N2), O(N3). The research task was to analyze the software code and specific conditions in which the algorithm refers to a particular type of computational complexity. The aim of analyzing the complexity of algorithms is to find the optimal algorithm for solving a specific problem. The criterion of optimality of the algorithm is chosen by the complexity of the algorithm, i.e., the number of elementary operations that must be performed to solve the problem using this algorithm. The complexity function is the ratio that connects the algorithm’s input data with the number of elementary operations. The paper contains a description of classical computational complexity that can be revealed by visual analysis of program code. The main types of computational complexity are (listed in descending order of efficiency) constant, logarithmic, linear, linear-logarithmic, quadratic, cubic. Also, methods for the determination of computational complexity are described. It is established that the main factors that can assess the algorithm’s computational complexity for the visual analysis of the software code are the presence of cycles, especially enclosed, reversibility of the algorithm, etc. Further research could usefully explore a method of semantic analysis of program code to predict the assessment of its computational complexity.
METHOD OF DATA TRANSMISSION PROTECTION IN CYBERPHYSICAL SYSTEMS
Authors: KLOTS Yurii , KORETSKA Luda ,   Khmelnytskyi National University
Published: April 2022

Wireless networks are used to transmit data in cyberphysical systems. This creates an opportunity for attackers to intercept information and then decrypt it and use it for malicious purposes. Consequently, the need to increase the protection of transmitted data in cyberphysical systems increases. This is made possible by new approaches to ensuring the cryptographic stability of the wireless security system. The purpose of ensuring the protection of data transmission in a cyberphysical system is to create a method of encryption that even when intercepting data by decryption was not possible. After sending the test sequence, the attacker hopes to obtain the key sequence that was used during the encryption as a result of decrypting this sequence (reverse operation the sum of module 2 to the encrypted sequence). Having a code sequence and intercepting the following blocks of information, their decryption will not be difficult. Using the coding method for cyberphysical system data before encryption allows you to change the statistical characteristics of the input sequence of elements (message length, data volume, entropy, probability of occurrence of characters). These are the statistical characteristics that an attacker needs to decrypt data. Using encryption before encryption does not allow you to select the input test sequence and obtain the key. The statistical characteristics of the input data and the data obtained as a result of encoding (compression) before encryption were determined; it is established that the use of the proposed method allows to obtain data that are statistically independent of each other in the input and coded sequence; it is shown that the method of protection of data transmission in the cyberphysical system is working and allows to protect data of different volumes.

Published: April 2022

The aim of the work is statistical analysis of the results of simulation modeling of the information security incident response team (ISIRT) depending on the parameter of increasing the intensity of the flow of information security incidents. ISIRT is considered as a queuing system in conditions of increasing load intensity. As input parameters for simulation the intensity of receipt of applications, characteristics of increase of intensity, characteristics of service of applications of ISIRT are used. The developed computer program sets random values of these parameters, distributed according to the indicator law. For each set of values, a set of stationary values is calculated, which characterizes the efficiency of ISIRT, as selected probabilities of operating modes and expectations. The program performs statistical analysis of the obtained values. As a result of the simulation, quantitative values were obtained both for the average values ​​and for the indicators of variability of characteristics that describe the effectiveness of ISIRT. The simulation showed the ability to predict the statistical patterns of cyber-attacks on the effectiveness of ISIRT. Tracking the statistical characteristics of incidents in the process of deploying the current cyber-attack, it is possible in the process of cyber defense to replace one ISIRT with another, the statistical characteristics of which will provide the required level of protection. To implement this approach, the developed software can be used.
JUSTIFICATION OF A RATIONAL METHOD FOR RESTORING AGRICULTURAL EQUIPMENT PARTS
Authors:   Vinnytsia National Agrarian University, BRATSLAVETS B.
Published: April 2022

The article proposes a way to optimize the technological process of updating parts according to the energy criterion. The rational development of technological processes for the restoration of specific parts of agricultural machinery is mainly determined by the choice of a method that ensures the greatest durability of the part at the lowest cost of their restoration. Currently, repair companies have a significant number of ways to restore parts used to eliminate various defects – (wear, mechanical damage, cracks, etc.). Rationale for choosing the best way to restore a part or group of parts in a set of technical, economic and organizational issues. For different types of recovery methods, such as surfacing and iron, when capital investment is significantly different, the technical and economic criteria should be determined through the above costs. However, even in this case, in practice, as a rule, many factors are not taken into account. To restore the same part, several methods are suitable, often unequal in their technical and economic indicators. Thus, to assess the renewal of a specific part in a specific production environment, they are refined. The energy criterion is especially important to use when decisions are made about the development of a new production, the construction of a plant or a large workshop for the restoration of parts. This is due to the fact that today the main parameter is the cost of restoring parts or costs, which in practice are largely influenced by prices, and real production costs, the novelty of the technological process, all energy costs, including , living labor for the production of products (energy criterion).

Published: April 2022

The article considers the results of qualimetric examination of methods of technical diagnostics of hydraulic systems. The theoretical analysis of methods of technical diagnostics of hydraulic systems is carried out, where their characteristics were studied and the advantages and disadvantages of each method from the list are considered. Also, the criteria that guide the choice of a method of diagnostics of hydraulic systems were determined, a matrix of evaluations of experts to assess the informativeness of methods of technical diagnostics of hydraulic systems. The results of the examination on the criterion “signal / noise” were processed. Thus, according to the results of expert evaluation, the most preferred methods for the diagnosis of hydraulic systems are: the method of diagnosis by the parameters of the working fluid, temporal, vibroacoustic and thermal methods. Use of the chosen diagnostic methods will allow to estimate precisely a technical condition of hydraulic system and its residual technical resource. The classification of methods of technical diagnostics of hydraulic systems on the basis of which the comparative analysis of these methods is executed is presented. Mathematical procedures for processing the matrix of expert estimates using the signal-to-noise criterion are also considered. Based on the results of evaluation of diagnostic methods of hydraulic systems of technological equipment for various purposes using the criterion “signal / noise” a certain combination of methods can be formed, which will be optimal for assessing the technical condition of hydraulic system of a particular technological machine.
GENERALIZED MATHEMATICAL MODEL OF VIBRATIONS OF A VERTICAL AXIS ROTARY SYSTEM
Authors:   Khmelnytskyi National University, DRACH Ilona
Published: April 2022

The rotor’s response to dynamic actions depends on its physical parameters and the parameters of the supporting structure. The vibration measured on the bearings or on the rotor shaft, in addition to the physical properties of the rotor, also depends on the value of the unbalance, its distribution along the rotor axis, as well as on the rotational speed. These factors influence the choice of the balancing method. This article proposes a dynamic model of a rotary machine with a vertical axis of rotation and six degrees of freedom. Differential equations of free and forced oscillations of the rotor system are compiled. It is shown that when considering the general case of oscillations of the rotor system, there is a high connectivity of oscillations along all generalized coordinates. Based on the analysis of differential equations, ways of reducing vibration activity and connectivity of machine vibrations are shown, which provide for: reduction of the center of mass of the platform to the axis of rotation of the rotor; alignment of the center of stiffness of the elastic support system with the center of gravity of the platform, and the main axes of stiffness and constant viscous friction of dampers with the main central axes of inertia of the platform; the use of vertical suspensions for the oscillating system in the construction of the machine; replacement of the elastic sealing diaphragm of the rotor with a non-rigid one. The above measures to reduce the connectivity of vibrations and vibration activity do not completely eliminate the vibrations of the machine caused by stochastic, variable imbalances. Therefore, a further decrease in the vibration activity of the machine can be associated with the use of auto-ballasting devices, which make it possible to reduce the disturbing forces by reducing the magnitude of the stochastic imbalances of the rotary machine.

Published: April 2022

The article envisages the increase in the efficiency of NC machine tool due to the use of an upgrades design of turning table for installation and fixing of workpieces, the use of which will lead to improved productivity of machining. With the help of a turning table it is possible to perform machining of workpieces of different shapes from several sides without resetting, and to rotate the workpiece in different coordinates to carry out other technological transitions. Such tables are widely used un multi-position hole machining, milling planes on drilling and milling machines. The workpiece is fastened to the turning table by T-shaped longitudinal seams, and the table can take vertical or horizontal position. Ways to reduce the cost of CNC equipment for small enterprises are analyzed. One possible way is to modernize turning tables by replacing the manual drive. When upgrading the table for replacement of the manual drive a stepper motor is installed, which transmits the movement through the coupling and worm-and-worm gear to the faceplate. Modern stepper electric motors provide movement of the work part with an accuracy of 0.01 mm. In addition, the have good operational life due to the lack of a collector unit (in comparison with servo drives), which is subject to considerable wear during operation. Due to the simplicity of design stepper motors have relatively low cost, which is of great importance in today’s production realities. The analysis of operating life and accuracy of modern stepper motors and the choice of motor was carried out.

The heterogeneous structure of massive heatonic radiation in the form of Fermi-liquid bubbles filled with Bose gas is analyzed. Such radiation is generated by dissipative vortex-wave packets and is absorbed by collector packets in nonequilibrium environments: technical, space, pseudo-elementary, biological. The results of calculations reflecting the internal dynamics and spectral features of heatonic radiation in systems of different scale levels are presented. The effects of phase mode synchronization and multiwave interference in the generation of heatonic resonances in technical and collider experiments are noted. On the basis of the extended analog of Planck’s constant the processes of self-organization and cascade transport of energy in the environment of heatonic radiation, and also mechanisms of its conversion into stable and quasi-stable forms of matter are explained. It is shown that the nonstationarity of dynamic processes in a heterogeneous system is caused by a violation of the balance between the exchange repulsion of shell fermions and the exchange attraction of quanta of internal Bose gas. Spectra of giant nuclear resonances and muon collider resonances are calculated. The lepton structure of hadrons was revealed, which rejects the need for artificial introduction of point quarks and testifies to the complete inadequacy of the existing standard model of fundamental interactions (SM). It has been noted that Einstein’s widely used formula, for the relationship between mass and rest energy lacks the cosine factor of the angle between momentum and the group velocity of quanta, which explains the difference between particles and antiparticles of matter.

The perspective of neural networks equivalental models (EM) base on vector-matrix procedure with basic operations of continuous and neuro-fuzzy logic (equivalence, absolute difference) are shown. Capacity on base EMs exceeded the amount of neurons in 4-10 times. This is larger than others neural networks paradigms. Amount neurons of this neural networks on base EMs may be 10 – 100 thousand. The base operations in EMs are normalized equivalence operations. The family of new operations “equivalence” and “non-equivalence” of neuro-fuzzy logic’s, which we have elaborated on the based of such generalized operations of fuzzy-logic’s as fuzzy negation, t-norm and s-norm are shown. Generalized rules of construction of new functions (operations) “equivalence” which uses operations of t-norm and s-norm to fuzzy negation are proposed. Despite the wide variety of types of operations on fuzzy sets and fuzzy relations and the related variety of new synthesized equivalence operations based on them, it is possible and necessary to select basic operations, taking into account their functional completeness in the corresponding algebras of continuous logic, as well as their most effective circuitry implementations. Among these elements the following should be underlined: 1) the element which fulfills the operation of limited difference; 2) the element which algebraic product (intensifier with controlled coefficient of transmission or multiplier of analog signals); 3) the element which fulfills a sample summarizing (uniting) of signals (including the one during normalizing). The basic element of pixel cells for the construction of hardware accelerators EM NM is a node on the current-reflecting mirrors (CM), which implements the operation of a limited difference (LD) of continuous logic (CL). Synthesized structures which realize on the basic of these elements the whole spectrum of required operations: t-norm, s-norm and new operations – “equivalence” are shown. These realizations on the basic of CMOS transistors current mirror represent the circuit with analog and time-pulse optical input signals. Possibilities of “equivalence” circuits synthesis by such functions limited difference cells are shown. Such circuits consist of several dozen CMOS transistors, have low power supply voltage (1.8…3.3V), the range of an input photocurrent is 0.1…24 μA, the transformation time is less than 1 μs, low power consumption (microwatts). The circuits and the simulation results of their design with OrCAD are shown.

The article is devoted to the analysis of methods of stabilization of photo-video camera and image, advantages and disadvantages of different methods of camera stabilization in order to improve the quality of photo and video shooting. The optical image stabilization system is an automated control system. In its composition, it must have a motion sensor, such as a gyroscope or accelerometer, analog or digital computing device and an actuator for motion compensation (motor). The purpose of such a control system is to maintain a fixed position relative to the inertial coordinate system, line of sight or light beam that passes through the camera lens and falls on the light-sensitive matrix. It is possible to realize it by means of the electric motor on the basis of the information from sensors. The electric motor rotates a certain stabilized optical unit, which in turn refracts the light beam. This unit is made with the possibility of rotation around the vertical and horizontal axes or the axes of the course and pitch. The optical unit rotates so that the projection of the image on the film or light-sensitive matrix fully compensates for camera shake during exposure. As a result, the projection always remains stationary with respect to the light-sensitive matrix for small oscillations of the camera. This provides the necessary image clarity. The steadic camera stabilization device provides smooth camera movement in different planes. Steadicams are used in film and video shooting, as it is the easiest way to get a quality picture in motion without shaking with minimal cost. To ensure high accuracy of image stabilization, it is proposed to use an optical stabilization system based on image stabilization. It can be used for photo and video equipment and even in systems such as binoculars and sights.

Due to the variety of existing and future wireless services, the number of antennas installed on a vehicle is constantly increasing. However, due to design limitations or the addition of more components of electrical equipment, the number of user-friendly antenna positions is reduced. To ensure stable data connections or even higher data rates with the remaining installation space, a possible solution is to use multiple antenna systems. This document discusses and evaluates 16 possible positions of antennas for communication between cars (C2C). The radiation pattern of all antennas is determined by the antenna synthesis maximization method, which takes into account real-world limitations such as space availability, transmission power, number and location of antennas. Channel bandwidth is used to compare different settings. This bandwidth is calculated using virtual disks based on typical application scenarios. The results of this study show which antenna positions and which combinations of antenna positions are most suitable for communication between C2C. Additional time and cost constraints, as well as an increase in the range of products for the automotive industry and a large number of degrees of freedom for the multi-purpose antenna necessitate the use of advanced modeling models and design strategies. Thus, this is the starting point for this work. Here is presented and used a technique that allows you to optimize single and multiple antenna systems. The main purpose of the proposed synthesis is to optimize the radiation profiles of antennas based on constraints specific to vehicles. For antenna design, this document identifies different scenarios based on typical C2C security scenarios. The simulation is carried out in a typical worst case in urban and rural areas or on highways.

The paper presents the development of a multi-channel frequency measurement system on FPGA by Altera Cyclone IV, the main task of which is to measure the informative parameter of sensors of physical quantities with frequency output. Based on the analysis of existing multi-channel frequency measurement systems on the FPGA, it is established that it is advisable to use multi-channel frequency meters for simultaneous measurement of several frequencies. Unlike several frequency meters operating simultaneously, multi-channel frequency meters perform measurements in a single time base, which is provided by a common exemplary generator and timer. A multi-channel universal FPGA-based measuring device has been developed, which has 12 measuring channels for frequency output sensors and supports simultaneous operation of 127 digital sensors via I2C interface. Therefore, theoretically, data transmission from the developed device can be carried out wirelessly. The developed device can be connected to a personal computer via a UART-USB converter. As a chip for the implementation of the frequency meter is used FPGA company Altera EP4CE10F17C8 – a chip in the BGA case, which has 179 pins. The parameters, namely the value of the signal propagation delay, determine the maximum measured frequency, in our case about 3 ns (delay of the signal from the input to the internal register), which corresponds theoretically to 333 MHz. Specialized software has been developed to test the efficiency of a multi-channel measuring system for measuring informative parameters obtained from radio measuring transducers, based on the reactive properties of semiconductor structures with negative resistance. For convenience of perception, there is a visualization of the received information from the measuring device.
