Authors: Molochko A. S.
Published: August 2023

The article examines the peculiarities of the formation of the highest sportsmanship of athletes in professional boxing. A comparative analysis of the dynamics of competitive activity of men and women during many years of performances in the professional arena was carried out. Considered options for building a professional career of boxers, taking into account the experience of performances in prestigious amateur competitions, as well as existing trends of liberalization and globalization of the modern Olympic movement. The individual dynamics of the long-term career of famous male and female professional boxers, who at one time owned championship belts in various weight categories, are presented. The optimal age range for demonstrating the highest sports results in boxing has been determined. The influence of international sports organizations (WBC, WBA, WBO, IBF, etc.) on the formation of sports careers of athletes in professional boxing is analyzed.

Systematized and considered stages of formation of the highest sportsmanship in professional boxing: 1) formative stage of 18-24 years (quantitative intensification of competitive activity); 2) - the stage of optimal opportunities (championship phase) - 25-35 years; 3) the stage of preservation and gradual decline of sports results - 35 years and more. It has been established that men have a longer formative phase of their professional career, which is characterized by a significantly greater number of preparatory matches in the initial stages of its formation and a longer period of time to maintain the achieved results in the final stages of multi-year improvement. The need to take into account the important regularities of the formation of the highest sportsmanship in boxing and the rational logistics of planning matches during the annual training cycle, taking into account the stage of the sports career and the age of the athletes, is substantiated.

Published: August 2023

The article analyzes motor activity in various competitive powerlifting exercises, which made it possible to develop a training plan for a shock microcycle in the preparatory period for young athletes of the experimental group. The performance of any physical or strength exercise is associated with a certain mode of muscle work, and muscle strength increases significantly. In powerlifting, competitive exercises are: squats with a barbell on the shoulders, bench press, deadlift. The purpose of the work is to develop sets of exercises based on muscle groups that ensure the performance of competitive exercises in powerlifting by young powerlifters 16-17 years old. The maximum force that a person can show depends, on the one hand, on the biomechanical characteristics of the movement (the length of the shoulder levers, the possibility of its implementation with the help of the largest muscles, etc.), on the other hand, on the magnitude of the tension of individual muscle groups. The study involved young puerlifters 16-17 years old in the amount of 24 athletes. The control group carried out the training process according to the traditional methodology used in the Youth Sports School. Experimental according to the methodology developed by us, taking into account the use of complexes of exercises for each competitive exercise. In the course of the study, it was determined that, thanks to the knowledge of the anatomy of the muscles involved in a particular movement, it is possible to modify any exercise to obtain the desired result in the formation of the muscles of the shoulder girdle or muscles of the chest, back, arms, legs, buttocks or abdomen, as well as improve the technique of performing any exercise. Testing carried out at the end of the preparatory period indicates more significant results of the experimental groups in relation to the control group in bench press (t=3,23, p<0,01), squat with a barbell (t=2,93, p<0,05 ), and deadlift (t=2,20, p<0,05).

Authors: Ahmed Firoz , Kabir Hasnat , Islam Touhidul
Published: August 2023

The demand of small, lightweight and high effectiveness antennas has increased significantly with the development of communication technologies. Microstrip patch antennas (MPAs) are one of the most widely used types of antenna that can satisfy these requirements. MPAs have numerous benefits, including tiny size and weight, ease of fabrication, and inexpensive. In addition to these advantages, MPAs also have some drawbacks such as limited bandwidth and low efficiency. In this paper, a compact rectangular patch microstrip antenna employing hybrid technique (HT) is designed to enhance the bandwidth and efficiency and its performance is compared with that of a conventional antenna. The HT is formed by combining a slotted patch with a defected partial ground structure. A low-cost FR-4_epoxy substrate material with a dielectric constant of 4.4, a thickness of 0.8 mm and a loss tangent of 0.02 is used to make both antennas designed. The antennas are designed, analyzed and simulated at the operating frequency of 6.85 GHz for ultra-wideband (UWB) (3.1-10.6GHz) applications using high-frequency structure simulator (HFSS) software. The overall size of the proposed antenna is 30 mm × 20 mm × 0.8 mm. A 50 Ω microstrip feedline is used to excite the patch. The outcomes of the simulation reveal that the suggested and conventional antennas achieved a bandwidth of 19.7 GHz and 2.53 GHz with an efficiency of 95.779% and 92.296% respectively. The recommended antenna has boosted in bandwidth and efficiency by 17.17 GHz (137.24%) and 3.483% respectively as compared to the traditional antenna.

Cutting temperature of graphene reinforced ceramic cutting tool inserts during dry turning of hardened steels
Authors: Vandana K. I. Vishnu
Published: August 2023

The amount of heat generated during machining operations under high speed and depth of cut inherently produces high temperatures at the cutting zone. Therefore, the temperature generated at the cutting junction of the tool and workpiece is a crucial parameter in determining the quality of the finished product. The effect of the generated cutting temperature, especially at elevated temperatures, primarily affects both the workpiece and the cutting tool. Knowledge of the cutting temperature generated at the tool tip can improve tool life and machining performance. In this work, turning operations were performed on a hardened steel workpiece of grade EN24 and EN36 using alumina-graphene composite ceramic tool inserts under different machining conditions on a precision lathe without coolant (dry machining). The maximum temperatures generated (offset temperature, i.e., 4 mm away from the tool insert tip) at the tool insert were measured during the turning of hardened steel workpieces with the aid of a calibrated thermocouple. A study was also conducted on the effect of different weight percentages of graphene in alumina ceramic tool inserts on the generated offset temperatures. During the machining of both the EN24 and EN36 samples, it was clearly observed that offset temperatures generated at composite tool inserts reinforced with 0.35 wt% and 0.45 wt% of graphene were lower at all machining conditions compared to offset temperature values generated at 0.15 wt%, 0.25 wt%, 0.55 wt%, 0.65 wt% graphene-reinforced alumina ceramic tool inserts, as well as pure alumina tool inserts.
An extension of TOPSIS method using interval bipolar linguistic neutrosophic set and its application
Authors: Quynh Vu Thi Nhu
Published: August 2023

TOPSIS, known as the “Technique for Order of Preference by Similarity to Ideal Solution” (TOPSIS), is one of the well-known methods for solving “multi-criteria decision-making” (MCDM) problems. Many TOPSIS methods have been developed to solve real-life problems using neutrosophic sets. However, no study has developed the TOPSIS method under interval bipolar linguistic neutrosophic environments. Therefore, this study aims to present a new concept of “interval bipolar linguistic neutrosophic set” (IBL_NS). IBL_NS is more flexible and adaptable to real-world applications than other sets. Some set-theoretic operations, such as “union”, “intersection”, and “complement”, and the “operational rules” of IBL_NS are defined. Then, a new TOPSIS procedure in IBL_NS is developed. In the proposed IBL_NS-TOPSIS method, ratings of alternatives and importance weights of criteria are expressed in IBL_NS. An application is presented demonstrating the advantages of the proposed IBL_NS-TOPSIS approach.

Authors: Akbulaev Nurkhodzha , Muradzada Imangulu
Published: August 2023

The aim of this study, unlike the studies in the literature, is to investigate whether the causal relationship between economic growth, export and import changes over time. In this study, it was analyzed whether the foreign trade of Azerbaijan and Italy had an effect on economic growth between 1992 and 2020. Granger causality and unit root test were used in the study. According to the test results, a causal relationship between growth and foreign trade has been determined for the Azerbaijan economy. However, a causal relationship between growth and foreign trade could not be determined for the Italian economy. According to the results of the analysis, the reason why such a relationship does not exist for Italy is due to the fact that growth is a factor that increases current account deficits and foreign trade deficit. In the relationship between foreign trade and economic growth, the direction and importance of the relationship may change according to the country and period. According to the Granger causality test, it has been determined that Azerbaijan's economic growth is the cause of its exports and imports with Italy with the condition of 10%. However, it has been determined that the foreign trade with Azerbaijan is not the reason for the economic growth of Italy.

In response to the growing desire for cities to be safer, more livable, and sustainable, Crime Prevention Through Environmental Design (CPTED) is a promising option. While the influence of CPTED on crime reduction has been widely documented, further research into its impact on broader dimensions of urban livability is required. This study aims to fill this research void by undertaking an extensive comparative analysis to uncover similar trends, variances, and best practices of livability in two CPTED-enhanced neighbourhoods in Bengaluru: Malleswaram and Jayanagar.

The study uses rigorous mixed-methods research to give a multidimensional understanding of the impacts of CPTED practices on urban living in the context of these two distinct neighbourhoods. The research design incorporates quantitative surveys, qualitative interviews, and comprehensive field observations to capture the varied viewpoints and nuances of individuals' lived experiences determined by common physical and social factors found to overlap between livability and CPTED such as Community Engagement, Land-use mix, Building visibility and Pedestrian infrastructure to name a few.

Finally, the results support the notion that CPTED is more than just a crime-reduction approach; it is a robust tool promoting sustainable and people-centred urban landscapes. By embracing the lessons acquired from Malleswaram and Jayanagar, it is possible to work collaboratively to create cities prioritising safety, community participation, social cohesion, and overall well-being for all people. As urban surroundings adapt, integrating CPTED principles should remain essential in creating thriving and inclusive communities for future generations.

An overview of the existing methods of measuring static stresses at elevated temperatures, at which it is problematic to use classical strain gauges, and methods of compensating the imaginary temperature deformation was performed. Namely: the use of multi-component alloys, the manufacture of active and compensatory sensitive elements from different alloys, which should theoretically compensate for each other's shortcomings. In practice, this can be sufficiently achieved only in a narrow temperature range. The described primary transducer is a rectangular strain-gauge rosette for measuring static and thermal stresses in structural parts operating under extreme conditions at temperatures up to 700°C. This sensor is a two-layer rosette consisting of two sensitive elements (SE), the main axes of which are rotated relative to each other by 90°. The lower SE perceives the main deformation of the part, and the upper one, located above the lower one, plays the role of a temperature-compensating electrical resistance of the element and simultaneously registers the transverse deformation of the part. SE rosettes were made of a wire with a diameter of 30 microns of the Х20Н80 alloy and fixed to each other and to the part using Ц-165-32А cement. The experimental study consisted in determining the temperature characteristics of the resistance of both the lower and the upper SE of the studied strain gauge associated with the temperature expansion of the part-strain gauge system as well as with the shunting of the insulator-connector and the change in the specific resistance of the SE material. Experimental determination of apparent strain gauge deformation at different temperatures was performed. To determine the influence of the coefficient of linear expansion of the material of the part on the change in the resistance of the SE, strain gauges were attached to samples of various materials. The change in the apparent deformation of the strain gauge in the temperature range from room temperature to 700 °C is shown. Its maximum value for the ceramic sample was less than 350 µm/m, for the 30ХГСА steel sample it was less than 1000 µm/m, and for the ВЖЛ14Н-ВІ alloy sample it was less than 750 µm/m. Dependencies were obtained that allow corrections to be made in the result of a real study of the stressed state of the part to achieve the maximum accuracy of measurements.

The subject of the study is the process of forming a mathematical model (MM) of an aviation gas turbine engine, which provides the calculation of parameters of the work process in stable and transient operating modes for use in the evaluation of dynamic characteristics, in the analysis and synthesis of automatic engine and aircraft control systems, as part of aviation simulators, and in on-board control and diagnostics algorithms. The goal is to substantiate the structure and methodology of MM formation, intended for use in real and accelerated time scale systems. Task: formulation of requirements for MM, substantiation of the interaction between static and dynamic submodels, substantiation of the composition of arguments and the way of considering the influence of external conditions, as well as the position of the elements of the mechanization of the gas flow duct. For this, the methods of the theory of airjet engines are used. The following results were obtained: the requirements for MM of aircraft gas turbine engines designed to solve the problems of engine and aircraft control were formulated, and the structural forms of MM were substantiated, which ensure high accuracy of modeling with minimal complexity and the possibility of real-time implementation. The scientific and practical novelty of the obtained results is as follows: the requirements for dynamic MM of aircraft engines have been summarized, the problems of structural implementation and combination of static and dynamic submodels, the rational selection of their input parameters and considering the influence of external conditions on static and dynamic characteristics have been analyzed, the software implementation of MM in in the Matlab Simulink environment of a two-shaft turbofan engine and compared the simulation results obtained using the developed simplified MM and the original nonlinear thermo-gas-dynamic model based on the solution of the joint operation equations of components. It is shown that in the working range of modes, the MM error does not exceed 5%, the dynamic errors of the rotor rotation frequencies are less than 4%, the compressor pressure and gas temperature are less than 7%, or the thrust is less than 10%. Errors in estimating the duration of acceleration and deceleration of the engine are within 0.2...0.6 s.

Despite significant progress in the development of modern unmanned aerial vehicles (UAVs), universal launch systems are not currently used for them. In fact, each UAV project requires its own launcher, which is inefficient in many cases. To evaluate the characteristics of UAV launchers, simple methods are used at the level of analysis of acting forces, but they do not make it possible to correctly select the type and parameters of the catapult for specific tasks. The object of this study was a universal pneumatic launch system for operational-tactical UAVs. The purpose of this study is to select the design scheme and basic parameters of a universal pneumatic catapult for UAVs of the operational-tactical class. The task: to develop and numerically solve a mathematical model of a pneumatic catapult, perform an analysis of characteristics, justify the choice of a design scheme and main parameters of a pneumatic catapult when changing the initial parameters within broad limits. Method of the study. The thermodynamic method was used with the help of which the differential equations of motion of structural elements were compiled and solved for various combinations of parameters. The results. By modeling, the main characteristics of the catapult were obtained and it was shown that for the effective functioning of the launcher, no special pneumatic cylinder piston sealing is required; the air leakage through the gap is controlled due to the short process time even at high operating pressures. In addition, the permissible minimum height of the cable attachment point on the trolley above the block roller was determined below which the loads on the cable and piston increased sharply. Conclusions. The developed model confirmed the versatility of using the pneumatic launcher of the scheme under consideration for operational and operational-tactical UAVs with a take-off weight of 50 to 250 kg, and such a wide range is provided only by regulating the air pressure in the receiver and is not available for other types of systems. At the same time, if the increase in pressure is limited by safety requirements, the possibility of further increasing the takeoff weight of the UAV in the launch scheme under consideration will remain by increasing the diameter of the pneumatic cylinder.
