Authors:   State University of Telecommunications, Varfolomeyeva O. H. , Zakharzhevskyy A. H.
Published: September 2023

In the article, necessity of monitoring telecommunication subsystems of complex security systems is substantiated. A simulation model is proposed, which makes it possible to form elements of a time series, in the role of which the moments of the beginning of the transmission of messages act. The possibility of forming both stationary and non-stationary flows of events is foreseen. The results of research on the main methods of time series analysis are presented. It is shown that the used approaches do not allow detecting possible anomalous traffic states with the necessary efficiency and reliability. It is proposed to consider the telecommunication system as a dynamic system for the evaluation of different traffic states. Analytical expressions for the formation of dynamic variables, on the basis of which phase portraits are formed, are presented. The obtained results of the experiments confirmed the informativeness of the proposed variant of traffic display. It is shown that the assessment of the state of telecommunication systems using phase portraits makes it possible to detect abnormal traffic conditions, as well as to predict the behavior of a dynamic system in the future.

Authors: Fedorin Andrei
Published: September 2023

The text of the “Continuation of the complete collection of the historical notes of Dai Viet” available for us is a fundamental source of the history of ancient and medieval Vietnam covers the events in this country from ancient times to 1675.Meanwhile the canonical text of this chronicle, distributed in the form of xylographsin the late 18 century, brought the description up to 1740.However, as a result of a significant revision of its final part carried out for political reasons under the first emperors of the Nguyen dynasty (1802-1945)the canonical text was drastically reduced, and the description of the last 65 years (1676-1740) was excluded from it altogether. At the same time, not a single complete xylograph of the original text of the chronicle, as it was formed in the 18th century, has reached our time. The article describes the history of the creation of this chronicle, its fundamental differences from Chinese sources, which certainly served as a model for it, primarily by highlighting its didactic function as the main one. As a result, this "unified history textbook" has always been an important part in the training system of Vietnam's medieval bureaucracy, its text was very stable and changed only for political reasons (during the transition to power of a new dynasty), most often due to significant reduction. This article is devoted to the questions of how is itpossible to at least partially restore the original version of the source and his lost text for the period from 1676 to 1740.

Authors: Aktamov Innokentii
Published: September 2023

The article is devoted to a brief overview of the main trends in educational cooperation between Russia, China and Mongolia. The focus of the research is the Inner Mongolia Autonomous Region as a special cultural and educational space within which interaction in the field of higher education is implemented. Based on statistical data, it was revealed that students from Mongolia and the regions of Siberia and the Russian Far East represent the overwhelming majority in the proportion of foreign students in the region. The main "attraction factors" are scholarship programs at various levels — the Government of the People's Republic of China, the People's Government of Inner Mongolia and universities. A significant incentive is the allocation of special quotas for applicants from Mongolia, as well as partner universities from Russia. The universities of the Inner Mongolia Autonomous Region over the past 15 years have become one of the key centers for attracting foreign students from Mongolia and the Russian regions of Inner Asia. The Chinese leadership considers Inner Mongolia as an important region for the implementation of domestic national policy. In recent years, this region has played an important role in building relations with Mongolia and Russia in the context of China's global initiatives and humanitarian cooperation in general. Quite possibly that in the future Inner Mongolia will fulfill strategic tasks both from the point of view of domestic policy and from the implementation of the PR China's foreign policy.

Published: September 2023

The article is devoted to Japan's policy towards Oceania in the context of the growing confrontation in the region between the coalition of Western powers led by the United States, seeking to maintain and consolidate their dominant positions in Oceania, and China, which is increasingly gaining strength. The Pacific Region, with its important geostrategic position and huge resources, is becoming one of the fronts of the offensive launched by the United States and its allies to strengthen their dominant positions on the world stage. At the same time, China continues its systematic advance in the region, relying on its growing economic power, accumulated large financial assets and steadily increasing technological level. The political, economic, and military aspects of the interaction of the dominant countries in the region with small developing island states, as well as their positions in the context of increased competition and tension between the powers are studied.
Particular attention is paid to Japan's desire to strengthen relations with the countries of Oceania and search for its place while maintaining close ties with the United States and its allies. Japan and island States have deep historical ties and successfully cooperate in many areas. Security issues, economic and logistical interests of Tokyo play an important role in this cooperation. Extensive multilateral and bilateral mechanisms for interaction with Pacific island countries have been created, relying on which Tokyo secures its interests in the region.
 
An important role in this situation is played by the position of the Pacific island States, which are increasingly openly declaring their interest in developing relations with all parties, guided primarily by their own interests, the possibilities of obtaining financial and economic assistance to solve the serious problems that have accumulated in the region.

Published: September 2023

Torsional fretting behavior of TC4 titanium alloy has been investigated at different fretting parameters to explore the fretting wear resistance and wear mechanisms of titanium alloy. The fretting loops, dissipated friction energy and friction torque under different normal load (100N and 200N), angular displacement (±0.5° and ±2°) and frequency (10Hz and 15Hz) were studied to reveal the mechanical behavior during fretting. Results showed that normal load made difference in friction torque while angular displacement was the most important factor in dissipated friction energy. And fretting ran in gross slip regime under the above fretting parameters. Surface morphology of fretting scars was characterized by optical microscopy and scanning electron microscopy. The shape of fretting scars was hourglass, appearing narrow and shallow in the middle, wide and deep on both sides. The section profiles of the fretting scars were shape of “V”. Besides, wear depth and wear volume increased under larger normal load and angular displacement. SEM images depicted that adhesive wear, delamination and fatigue occurred during fretting.

Published: September 2023

Object detection performs a vital function in numerous domains. In contemporary object detection frameworks, multiple detection heads are a crucial element. Multi-performance head improvement is mostly attributable to the employment of many heads to detect objects of different sizes, but this also results in significant computing usage. Moreover, not all heads need to participate in the detecting process for every image. We first investigate the correlation between the number of heads and computing consumption, explore how to determine whether a detection head is in charge of detecting an object, and propose a dynamic head network for detection (DH-Net), which according to the input photographs, adaptively pick which heads to make predictions. As a result, the technique can accomplish more effective dynamic reasoning and a better balance between detection accuracy and computing expense. DH-Net allows the model to lower the number of parameters by up to 34% while still maintaining comparable accuracy, according to a series of controlled trials in the TT100K datasets. Moreover, it has the effect of speeding up training for redundant models.

Authors: Liu Guang , Wan Ran , Hu Jie , Wang Ji
Published: September 2023

A mathematical model for predicting an unstable working condition called cycling of a magnet-loaded pressure relief valve is proposed. The valve is connected by a long pipe to a reservoir used to store liquid cargo. A fluid dynamic equation in the pipe, with boundary conditions given by the valve mechanical equations and reservoir inflow equations is solved. The interaction of magnetic force and gravity is analyzed. Increasing the percentage of magnetic force in the overall resistance force of the valve moving part may effectively avoid the occurrence of cycling. A criterion for preventing cycling is proposed based on the simulation data, which is the initial magnetic force should at least occupy 30% of the overall initial resistance force working on the valve moving part. This criterion can be used in the design of the magnet-loaded pressure relief valve in engineering situations.

Published: September 2023

In the process of laser cladding, local heat input causes uneven temperature distribution and then produces thermal stress. The large temperature gradient in the melted-solidified region causes uneven plastic deformation due to solid-liquid phase change. In the study, based on the different types of heat source, the numerical models of single-layer and multi-layer laser cladding on single channel were established in virtue of the transient thermal-mechanical coupling analysis method. The three-dimensional residual stress fields of specific paths were established.

Published: September 2023

Carbon fiber reinforced polymer (CFRP) composites have been widely used in aviation, aerospace and other fields due to their excellent mechanical properties. However, it is difficult to observe delamination damage during the manufacturing, machining, assembling as well as transportation of composite materials, especially for joint structures. The delamination around joint hole is one of important factors for their service performance. In this paper, a model of composite laminate with delamination damage is established by combining numerical simulation methods and the experimental investigation of CFRP parts with delamination defects. Then, the influence of different delamination characteristics (diameter, position and shape) on the mechanical properties and failure process of the laminate under different loading conditions were investigated, and the results were verified through experimental validation. By comparing the experimental and simulation results, it can be concluded that all three factors have a great influence on the compressive static load strength and compressive fatigue life of the laminate, and the form of delamination expansion and stress distribution cloud diagram of the laminate under each delamination feature are also studied, to investigate the failure mechanism and the type of delamination expansion of the laminate. Finally, ANOVA was used to analyze the effects of different delamination characteristics on the compression strength and fatigue life of the laminates.

Research on Impact Resistance of Carbon-Ceramic Brake Disc Friction Surface to Foreign Particles
Authors: Wang Wenbin , Su Cong , Li Tong , Sang Xu
Published: September 2023

Based on the microscopic structure of fiber-reinforced composite materials, a finite element analysis model was developed using LS-DYNA software to simulate the damage of carbon-ceramic brake discs under high-speed foreign particles impact conditions. The model incorporated the Chang-Chang failure criterion to simulate intra-layer damage and introduced a material stiffness reduction scheme to investigate the failure process and damage mechanism of carbon-ceramic brake discs. The results show that the primary forms of damage to the carbon-ceramic brake discs are micro-cracks in the matrix and fiber compression failure. The majority of the energy dissipated during material damage and failure is absorbed by the unidirectional fiber layer, with the mesh layer absorbing relatively less energy. As the impact angle increases, the total energy absorption and total damage area of the carbon-ceramic brake disc also increase, and matrix tensile damage is the first to occur, followed by matrix compression damage, and finally fiber compression damage. As the initial velocity of the foreign particles increases, both the energy absorption and damage area of the carbon-ceramic disc showed an overall upward trend, and the rate of energy absorption growth is slow at first and then fast. The shape of the foreign particles has a significant effect on the distribution of damage to the brake disc, with spherical-shaped foreign particles causing more severe damage to the brake disc.

Authors: Jiang Yantao , Lai Yongcheng , Li Shiqi , Xiong Chuanyun
Published: September 2023

Taking axial compression ratio and velocity as variables, using the general finite element software ABAQUS, this paper simulates the behavior of H-beam under impact, and analyzes the impact resistance of this component. The result is that changes in the axial compression ratio mainly cause local damage, which can lead to changes in the degree of damage to such components. The impact resistance of such components can be increased by appropriate axial compression ratios, but the damage to the components is more severe than excessive axial compression; The change in velocity directly leads to a change in kinetic energy, causing a change in the force acting on the component, thus having a significant impact on the impact resistance of the component, with overall instability damage as the final form of damage.
Study on the Effect of Magnesium Phosphate Cement Mortar Coating on the Bond Performance of Strand
Authors: Wu Hao , Yi Ju
Published: September 2023

Surface coating is an effective method for preventing corrosion of strand. This article investigates the influence of Magnesium Phosphate Cement (MPC) mortar coating on the bonding performance of strand. Central tensile tests were conducted by varying the grouting thickness of the cylindrical packaging surrounding the strand, in order to study the bonding performance of different thicknesses of MPC mortar on the strand tensile specimens, including the effect on failure mode and bonding strength. When compared to traditional adhesive coatings like epoxy resin and uncoated specimens, it has been observed that the bond strength of MPC mortar initially increases and then decreases as the coating thickness varies. Furthermore, when the coating thickness surpasses 15 mm, its bond strength outperforms that of specimens lacking adhesive coatings. The bond strength between MPC mortar and steel strands is superior to epoxy resin, with an average enhancement of approximately 40%. Typically, the ultimate pull-out load constitutes around 15% of the initial displacement pull-out load.

The test is based on a block with a strength of MU10.0, and after reviewing the literature, fly ash with a mass fraction of 20%, recycled aggregate with a replacement rate of 70%, and flax fibre with a volume fraction of 0.3% are added. The empirical formula is used to calculate and propose the ratio of recycled concrete with flax fibre, and a novel structural design for a self-insulated block is also proposed. The compressive and thermal properties of the self-insulated blocks were finally simulated using ANSYS finite element software, and it was discovered that the blocks’ stress distribution was uniform and stable, with a maximum stress value of 13.19 Mpa and a minimum stress value of 8.79 Mpa. Additionally, the distribution of the heat flow density is more even and stable, and the heat flow transfer is concentrated more in the left portion of the block. According to the energy conservation equation of heat flow steady state, the block’s simulated heat transfer coefficient is 0.416 W/(m2·K), which satisfies the numerical requirements of the current energy conservation design standards for homes in cold and cold regions.

In comparison to regular concrete, scoria concrete is lighter on its own, has a higher strength, performs better during earthquakes, and is better at insulating heat. It has a good chance of being used in modern engineering structures, which can successfully reduce the weight and load of the building. This paper substitutes scoria for 20% of the cement, fly ash for 10% of the cement, and recycled aggregate for the 30% coarse aggregate by processing the waste concrete that accumulates in the city using specific technology. The research’s findings can be used in the design and construction of building envelopes in extremely cold climates. The compressive strength and thermal properties of scoria concrete self-insulated blocks were simulated by software using ANSYS finite element software. The block structure’s theoretical heat transfer coefficient is 427810428 W/(m·K), which is in accordance with the requirement that the enclosure structure’s thermal conductivity not exceed 0.5 W/(m·K) in areas of extreme cold in the north. The simulated and tested values were compared. This product provides reference for civil engineering construction.

And determine whether the impact of the pipe jacking construction on the railway in the city is controllable. The calculation results show that the method is rigorous and feasible by introducing an intelligent optimization algorithm to correct rock and soil parameters.
Dynamic Response Numerical Simulation and Performance Evaluation of SRC Columns Under Lateral Impact
Authors: Hu Zongbo
Published: September 2023

Using ANSYS/LS-DYNA finite element analysis software, numerical simulation was conducted on the dynamic response of steel reinforced concrete column under impact loads. The effects of different constraint conditions, impact mass, impact speed, and impact position on the impact resistance performance of SRC columns were studied. The results show that under the constraint of fixed-simple and the same velocity, the closer to the column end, the greater the impact force is; Under the same impact speed, the impact force of the cantilever column is significantly greater than that of the fixed constraint state. Under the action of fixed constraints and the same impact energy, the maximum displacement of the SRC column continuously increases with the increasing impact position. As the impact position continues to increase, the time when the maximum displacement occurs is also continuously delayed. Under the cantilever constraint condition, the maximum displacement of the SRC column is significantly greater than that of the fixed simple constraint state and the fixed-fixed constraint state. The maximum displacement of the SRC cantilever column occurs at the top, while under the fixed-fixed constraint condition, the maximum displacement of the SRC column occurs at the direct impact position. The maximum stress of steel under three constraint states all occur at the instantaneous and direct impact points, and the stress of the column steel rapidly decreases with the increase of SRC column displacement response; Under the action of a small amount of impact energy, the SRC column under cantilever constraint undergoes splitting failure at the impact location as the impact energy increases, and the final failure belongs to brittle failure.

The infusion of biology, like of the other natural sciences, by postmodern ideas is under harsh criticism. The reason behind this position is that the postmodern stance advocates for relativism and subjectivity, which are in sharp contrast with the aspired objectivity in the nature of the scientific method and the universality of the derived conclusions on which the sciences rely. Biology, though, is unique among the natural sciences in the fact that while it relies on the laws of chemistry and physics, when its distinct subject matter emerges, the one that is conceived as biological, it is based on random events that acquire their universality on the grounds of historicity. This offers biology a unique connection with the postmodern stance that instead of being hunted, it should be favored.

Legal Support of Effective Management of an Educational Institution in Wartime Conditions
Authors: Kotenova Olexandra , Maksymenko Mariia
Published: September 2023

The article is devoted to the analysis of the legal provision of effective management of an educational institution of Ukraine in wartime conditions, which consists of the effective application of situational management and elements of anti-crisis management. It was found that from February 24, 2022, the full-scale war of the russian federation against Ukraine exacerbated the problem of legal provision of effective management of an educational institution. An analysis of modern research on the issues of legal regulation and ensuring the effective management of an educational institution in war conditions was carried out (for example, information and analytical reports of the State Education Quality Service of Ukraine and reports on the quality of higher education from the National Agency for Quality Assurance of Higher Education). It was determined that the management of educational institutions in wartime conditions is characterized by: constant observation, detection and localization of problematic phenomena that occur in the educational environment of an educational institution; prevention of crisis situations. It was found that the current legal acts do not sufficiently regulate and ensure the effective management of an educational institution during wartime. An analysis of the existing legal provision regarding the management of an educational institution under martial law was carried out. It was concluded that in Ukraine there are gaps in the legal management of an educational institution in wartime conditions, namely: lack of necessary documents, recommendations, courses for teachers regarding actions in wartime conditions; lack of a strategy for compensating educational expenses of education seekers at the state level, etc.; lack of a permanent mechanism for the simultaneous functioning of various forms of education; lack of recommendations regarding the actions of educational institution managers and teaching staff in the event of destruction or damage to an educational institution; lack of recommendations regarding the targeted actions of educational institutions, employees of educational institutions, education management bodies, who found themselves in temporary occupation; there is no understanding of the possibilities of using autonomy in the development of management of an educational institution with existing legal support.
Sectorial Plane Wave Imaging for Weld Inspection Studies
Authors: Pillarisetti Lalith Sai Srinivas , Raju Gangadharan , Subramanian Anandamurugan
Published: September 2023

Advanced ultrasonic array–based imaging techniques that rely on A-scan data acquired through individual parallel reception of array elements and subsequent post-processing have shown promising performance by generating high-resolution images. An advanced array-based imaging algorithm called sectorial plane wave imaging (SPWI) has been recently proposed with multimode imaging and rapid inspection capabilities. In this work, the efficiency of the SPWI algorithm is demonstrated and compared to the total focusing method (TFM) and plane wave imaging (PWI) algorithms in detecting different types of common weld defects: lack of sidewall fusion, slag, porosity, toe crack, centerline crack, and root crack. The full matrix capture data acquired over each weld defect using a 32-element linear array on an angular wedge configuration is converted to the PWI matrix data to perform SPWI. The corner and indirect mode SPWI inspection results are able to detect all the weld defects with image quality comparable to that of TFM and PWI, but at a higher processing speed due to the slight compromise over reception focusing, making SPWI a viable advanced ultrasonic array–based imaging technique for inspecting welds.

Background and Aim: Adjacent segment disease (ASD), radiological and clinical, is observed in many of the patients who undergo cervical inter-body fusion with/without graft, and with/without plating. This study aims to evaluate the proportion of ASD among patients who underwent cervical spine fusion surgery, to study the severity of degenerative radiographic findings at adjacent levels, and to determine sites and patterns of ASD. Methods and Materials/Patients: A descriptive study was performed on patients who underwent a previous cervical arthrodesis procedure in the last 2-5 years and continued follow-up as neurosurgery outpatients. A total of 59 patients who qualified for the inclusion criteria were included in the study. Results: Spine fixation was commonly performed at a single level mostly with sample size (54.2%, n=32) then at two levels (42.4%, n=25) and three levels (3.4%, n=2). Adjacent segment degeneration was present in the spine fixation level subgroup at a single level of 9 cases (28.12%), two levels of 9 cases (36%), and three-level fixations of 2 cases (100%). Six patients (10.2%) out of 59 patients developed radiculopathy. Among twenty-two cases (37.3%) with new changes at adjacent levels, reduced disc height was the most common one (18.6%, n=11). Anterior and posterior osteophytes with reduced disc height were found in 2 cases. Therefore, actual new changes were present in 20 cases only. The most common level of C4-C5 was observed for the development of ASD (13.6%, n=8). ASD developed at cranial to fusion in 13 cases (22%), caudal to fusion in 5 cases (8.5%), and at both levels in 2 patients. Conclusion: Adjacent segment disease was observed in a significant number of patients who underwent cervical spine surgery as evident from the results but only 6 out of 20 cases with radiological evidence of ASD were symptomatic. Changes were observed commonly at the C4/C5 level.
