As Dental implants have emerged to be one of the best means of rehabilitating a missing tooth, there have been various new advancements taking place in implant dentistry in recent years. It is extremely important to preserve the facial bone and the soft tissue, especially in the esthetic zone. Various such procedures maintain the width of the soft tissue and underlying bone in the esthetic areas. Conventionally it was advisable to wait for at least 3 months after the implant placement, before prosthetically rehabilitating the patient. However, with recent advances, we can provide the patient with immediate implants. This review aims to discuss a technique, which discusses on how we are able to place dental implants in fresh extraction sockets, with a buccal plate defect incorporating a novel surgical method along with usage of both hard and soft tissue grafts, which will enable us to achieve pleasing esthetics for the patient, without causing future facial bone resorption.

Authors:   Vinnytsia National Agrarian University, Yalyna Olga
Published: February 2023

Hydraulic systems are used in almost all branches of agricultural machinery. They are widely used in production – for example, in foundry machines, presses, heavy manipulators, machine tools, works, molding machines for plastics. They play an important role in the operation of equipment designed for the mining and oil industry, in rescue equipment. And, of course, one of the widest areas of application for hydraulics is various kinds of special equipment: excavators and cranes, loaders, aerial platforms, agricultural, warehouse and many other types of machines. The use of hydraulic systems is due to a number of obvious advantages. First of all, they provide the efficiency of moving heavy loads with fine adjustment. Hydraulic systems also have great flexibility to control large and small forces. Another important benefit is reliability: equipment can be protected from overloading with simple pressure relief valves. Compared to the tasks they solve, hydraulic systems are compact and economical. The hydraulic system of any special equipment is a rather complex and precise mechanism. The performance of the machine largely depends on its ideal operation. An analysis of the development of modern foreign mobile machines, including earth-moving, leveling, lifting and transport, for the production of concrete work and soil compaction, agricultural and forestry machines, basic wheeled tractors, etc., revealed a trend towards a growing volumetric hydraulic drive. reciprocating and rotary motion. The author examines the modes of operation of the pulse hydraulic drive of the working bodies of agricultural machines, determines what their advantages and disadvantages, what types and designs of pulse hydraulic drives and how they affect the work process.
SELF-OSCILLATING PARAMETRIC PRESSURE SENSORS
Authors: OSADCHUK Jaroslav , OSADCHUK Alexander , OSADCHUK Vladimir ,   Vinnytsia National Technical University
Published: February 2023

Self-oscillating parametric pressure sensors are proposed based on transistor microelectronic structures with negative differential resistance with primary strain-sensing resistor and diode, and the primary strain-sensing elements are active elements of the self-oscillator circuit, which simplifies the design of pressure sensors. It is also proposed to replace the passive inductance of the self-oscillator oscillatory circuit with an active inductive element based on a transistor with a phase-shifting RC circuit, which makes it possible to expand the range of output frequency adjustment, as well as to fully produce pressure sensors using microelectronic technology. Based on the consideration of physical processes in primary strain-sensing elements and self-oscillators, mathematical models of pressure sensors have been developed, on the basis of which parametric dependences of the conversion and sensitivity functions have been obtained. It is shown that the main contribution to the change in the conversion function is made by the change in pressure. This causes a change in the equivalent capacitance and negative differential resistance of the oscillatory system of sensor self-oscillators, which in turn changes the output frequency of the devices. The sensitivity of the pressure sensors varies from 0.365 kHz/kPa to 2.45 kHz/kPa when the pressure changes from 0 kPa to 2050 kPa. The obtained parametric dependences of the conversion functions of pressure sensors show the possibility of easier calculation of the main characteristics of the sensors and clearly show the influence of each parameter of the primary converters and the parameters of the self-oscillator on the output frequency of the sensors in comparison with the calculations of the conversion functions based on the Kirchhoff equations. Pressure sensors with a frequency output do not require analog-to-digital converters and amplifying devices for further processing of information signals, which reduces the cost of information-measuring equipment, in addition, it is possible to transmit information over a distance when the sensors operate at microwave frequencies.

Published: February 2023

The scientific result presented in this paper consists in development of the Lame-Gadolin theory about interaction of joint thick-walled cylinders application to estimate strength of electronic components represented by bodies of revolution and surrounding layer of compound sealed by an arbitrary shape subjected to thermal impacts in the temperature range from +70 to -60 deg C. The difference in the coefficients of linear thermal expansion and other physical and mechanical characteristics of compound and electronic components under the temperature changes produces a contact pressure on their contact area causing thermal strain and stress in materials of both bodies in the sealed structure. Within the framework of the axisymmetric problem, the stress-strain condition of the electronic component-compound system has been assessed in condition of thermal impact, due to which the pattern of the maximum total radial, circumferential and axial stresses has been revealed depending on their radial distribution and the temperature load mode. The stress estimation in the S2-29V resistor sealed with the EZK-25 compound inside the sealed electronic package has been performed at the constant temperature drop. The experimental method is proposed for determining the ultimate stresses in electronic components sealed with compound under stress and strain condition identical to the operational one. Experimental measurement of circumferential and axial strains was carried out by using method of electrotensometry. Thermal impacts were reproduced in the thermostat and the climatic chamber. Technological methods for protection of electronic components in the structures of electronic packages sealed with compound has been proposed by embedding elastic and dissipative joints between electronic components and a sealant, and the effectiveness of their application is experimentally evaluated based on determination of the damping coefficient.

The paper presents the results of the development and modelling of a broadband antenna system for Unmanned Aerial Vehicle (UAV) direction finding. The research covered the issues of analytical description of the antenna system based on the prototype – the Vivaldi antennas. The article presents a mathematical description of the Vivaldi antenna element model. An experimental relationship between the geometrical parameters and characteristics of the antenna has been established. A review of the current state of the issue of designing antenna systems based on the concept of building ultra-wideband directional antenna elements in the absence of a phase centre has been carried out. The main trends in the modern design of broadband antenna systems are determined. The main parameters of the proposed broadband antenna are determined by the method of mathematical modelling. The parameters of the proposed antenna in the frequency range under various excitation conditions are studied, and the specifics of the application of such a system under the conditions of its possible use as part of UAV direction-finding complexes are given. The most optimal design option for an ultra-wideband antenna element is a design with an expanding slot (similar to Vivaldi antennas). At present, these antennas are widely used in various devices, namely, in radio reconnaissance devices, medical equipment, etc. Their popularity is due to the presence of advantages over other antennas, among which are a wide operating frequency range, simple design, simple manufacturing requirements, and high gain. In this paper, we considered Tapered Slot Antenna – an antenna with a widening slot. The antenna element designed and modelled in the article is a modified Vivaldi antenna (an antenna with a quasi-slot line with expansion), which is being developed for the direction-finding complex of the UAV. When calculating the TSA of the antenna element, the program for calculating the characteristics of the antennas MMANA was used in order to accelerate the study of the main laws for obtaining the required characteristics. Particular attention was paid to the possibility of changing the radiation pattern (RP) depending on the phase relations of the voltage at the input of the antenna elements.

Published: February 2023

The article considers ways to solve the problem of orientation of flat parts with different properties of surfaces that come to the working position of technological equipment. Mechanical methods of controlling the position of flat parts of footwear on the properties of surfaces are based on the use of asymmetry of their frictional properties or the magnitude of surface irregularities. In some cases, in the process of position control with the help of devices that implement these methods, it is possible to simultaneously transport the part to the working position of the process equipment or to the position of reorientation. Frictional properties of surfaces of any materials are characterized by the coefficient of friction, which depends on the elastic properties of the material, surface roughness, specific load and many other parameters that characterize the molecular interaction of surfaces in the contact zone. Most shoe materials have different frictional properties of the front and back surfaces. This provides the ability to automatically orient parts made of such materials on the basis of “front side – reverse side” using the differences in the frictional properties of the surfaces of the part. The use of rolls as sensors to control the position of flat shoe parts on the frictional properties of surfaces and simultaneous transportation of parts from the control position to the loading or reorientation position greatly simplifies the control operation, increases productivity and reliability of control devices. For correct installation of details on technological processing it is necessary to reveal their position and, in case of incorrect, to reorient. For this purpose, devices for position control on frictional properties and asymmetry of surface topography, as well as their design calculations are proposed.

Optoelectronic surveillance systems are widely used in many areas of human activity: in agriculture, medicine, military systems, in search and rescue operations. These systems are designed for space, airborne, ground and maritime applications. They have to work under all climate conditions with absolute certainty under all light and weather conditions. And on the other hand, they have to be cost effective. That’s why optoelectronic surveillance systems use channels which provide complimentary information about the object and background. And for the most applications channels that operate in visible and thermal ranges of optical spectrum are indispensable element of such systems. Optoelectronic surveillance systems have to continuously meet and even exceed today’s performance and reliability requirements. That’s why there is a need to use not only cutting-age technology, but also adaptive signal processing. Information fusion is state-of-the-art technic to improve overall system performance. Numerous image fusion methods have been proposed during several decades but the most promising are neural networks. Television system, which work in visible range of optical spectrum, and thermal system, which work in long-wave infrared range where chosen for the modeling. Probability of target detection, recognition and identification was used for performance evaluation. Probability of target detection, recognition and identification for separate long-wave infrared and television channels were modeled. Also, probabilities were estimated for the fused data. Information fusion was done with the help of convolutional neural networks. Simulation results showed that probability of target detection, recognition and identification are almost for 6% higher for fused data compared to separate channels.
ARBITRARY DURATION PULSE SHAPER

This paper considers the possibility of constructing a universal pulse generator based on TTL (transistor-transistor logic) elements, which provides pulses of a given duration at the time of entry to the input of the negative edge of the input start pulse (difference from logical unit to logical zero). The duration of the generated output pulse can be set by the capacitance of one capacitor and does not depend on the duration of the input pulse. A significant advantage of the proposed pulse shaper is the high steepness of both the positive front (difference from logical zero to logical unit) and the negative edge of the generated output pulse (difference from logical unit to logical zero), which depends only on the operation time of logical elements and not depends on the duration of both input (start) and output pulses. This advantage is based on the action of positive feedback at the time of formation of both positive and negative fronts of the output pulse. In this case, the feedback circuits in the formation of positive and negative fronts of the output pulse are different, which does not allow the circuit to switch to self-excitation mode (autogeneration). The advantages of the proposed pulse shaper (high steepness of the fronts with little complication of the circuit compared to the known capacitor pulse shapers) are determined by using the internal structure of the logic elements of the TTL series. This paper also considers the possibility of reducing the capacitance of the capacitor by several tens of times, which determines the duration of long output pulses, due to the introduction of an emitter repeater. The main disadvantage of the proposed pulse shaper is the low temperature and time stability of the duration of the formed output pulse, which is characteristic of all capacitor pulse shapers.

Proposed research method intensification of heat exchange in biogas reactions using alternative energy sources. The distribution of active and passive methods of heat exchange intensification is determined. The three most effective methods of heat exchange intensification are identified: the method of flow turbulence in the adjacent areas, based on purposeful artificial creation of small dry wall zones, which is the source of additional flow turbulence; the method of flow winding inside the twisted oval tubes and at longitudinal and transverse winding of tightly packed beams and tubes; the method of controlled break-out of the boundary layer at transverse tubulars by creating turboblicators on them. It is determined that in practice the most effective is the use of combined methods of intensification. The important conditions for choosing the method of heat exchange intensification are: the amount of permissible energy costs for heat exchange intensification and the type of energy available for this energy; the task of heat exchange intensification in a particular class of equipment; the technological capacity of equipment with heat exchange intensification, availability at purchase and durability in operation of equipment; the nature of distribution, structure of thermal flows and temperature fields, in which there is a need for intensification of heat exchange. The main indicator of intensification of the heat exchange process in the equipment is found – the efficiency of the process, that is, the process should be economically profitable. From the above it appears that the intensification of heat exchange can’t be considered isolated from the necessary energy costs. The determining criterion of optimization is the efficiency of the heat exchange process at a given level of energy consumption at transfer of the working environment through the equipment. Heat exchange intensification during use of gaseous working environments is of particular importance, for which characteristic reduction of intensity of heat exchange processes and high energy consumption for removal of supports at pumping of gases is characteristic. Tasks of heat exchange intensification are usually set: to reduce the size and weight of heat exchange devices; to decrease the temperature pressure, i.e. to decrease the temperature of the walls at the given temperature of heat carrier or to increase the temperature of heat carrier at the given temperature of walls. Reduction of thickness of heat transfer wall and increase of its thermal conductivity, as well as prevention waste contamination on the wall is an obvious method of intensification of heat exchange.

Mathematical knowledge is a term often used to describe various components of mathematical science, such as theorems, lemmas, axioms, proofs, etc.. By the term “knowledge from mathematical modeling” we understand the definition of a huge amount of knowledge, which is formalized both within the framework of a specific mathematical model and in the process of its construction, as well as related procedures of practical use. Compared to other forms of knowledge, such as rules, solution trees, mathematical knowledge is more abstract and more structured. In general, the ontological approach to mathematical modeling refers to the use of ontology, as it is based on the terms of mathematical modeling and descriptions of relationships between the main processes of its course.. The general ontological approach to mathematical modeling from an applied point of view does not allow to manage the processes of building mathematical models, because it can only be used to describe the area of mathematical modeling. From an applied point of view, most basic forms of mathematical knowledge are either embedded in specific software tools, such as models of aggregate operation in simulation software, or must be formally interpreted into a more general mathematical tool, following appropriate syntactic rules. Most of this type of knowledge relates to specific modeling tasks and is clearly implemented with the help of appropriate procedural descriptions, rather than declarative representations, unlike the philosophical vision of mathematical modeling. The paper substantiates the use of the ontological approach as an effective tool for managing the processes of building mathematical models based on interval data and using these models for applied problems. The use of the ontological model made it possible to formalize the process of obtaining, storing and using knowledge obtained in the process of mathematical modeling. The article also presents the features of building a software architecture for mathematical modeling based on interval analysis and an ontological approach. The technology for creating software based on the developed ontological add-on for mathematical modeling using interval data for various objects, as well as various forms of user interface implementation, is described. A number of diagrams illustrating the peculiarities of using the ontological approach based on interval data are presented and the peculiarities of its interpretation in applied fields, in particular, in the tasks of environmental monitoring, are described.

There are a few different ways to think about semantic compatibility in the context of electronic health records (EHRs). One way to think about it is in terms of the structure of the data. This would involve making sure that the data is organized in a way that is consistent with how other systems expect it to be organized. Another way to think about it is in terms of the meaning of the data. This would involve making sure that the data is annotated in a way that is consistent with how other systems expect it to be annotated. A third way to think about semantic compatibility is in terms of the use of the data. This would involve making sure that the data is used in a way that is consistent with how other systems expect it to be used. Each of these approaches has its own strengths and weaknesses. The approach that is most appropriate will depend on the specific context in which the EHR is being used. The structure of the data is the most important factor to consider when thinking about semantic compatibility. This is because the structure of the data determines how the data is organized and how it is accessed. If the structure of the data is not compatible with the structure of other systems, then the data will not be accessible to those systems. The meaning of the data is also important to consider when thinking about semantic compatibility. This is because the meaning of the data determines how the data is interpreted. If the meaning of the data is not compatible with the meaning of other systems, then the data will not be interpreted correctly by those systems. The use of the data is also important to consider when thinking about semantic compatibility. This is because the use of the data determines how the data is used. If the use of the data is not compatible with the use of other systems, then the data will not be used correctly by those systems. In general, the most important factor to consider when thinking about semantic compatibility is the structure of the data. The meaning of the data and the use of the data are also important factors to consider, but they are not as important as the structure of the data.
