Authors: Chen Qingguang , Shi Xiaojie , Xu Jin , Dai Yunlong
Published: May 2024

In order to improve the stability margin of the fan, the FBCDZ-No20 contra-rotating fan is selected as the research object, and the influence of the coupling effect of the axial position and the depth of the circumferential groove on the stability margin of the fan was explored. Numerical simulation shows that the circumferential groove casing treatment in the front stage can realize the effective stability margin improvement of the fan, in which the 30mm circumferential grooves located at 25% axial chord length can can make the fan obtain considerable stability margin improvement. However, the implementation of circumferential groove reduces the peak efficiency of the fan where the circumferential groove located at 25% of the axial chord length leads to a larger loss of peak efficiency of the fan, and the loss of peak efficiency also increases with the increase of the groove depth. Compared with the groove depth, the axial position of the circumferential groove has a more significant effect on the stability margin of the fan, shallow circumferential grooves in favorable axial positions can compensate for the lack of shallow grooves, whereas deeper circumferential grooves in unfavorable positions cannot reflect the advantages of the deep groove.

Published: May 2024

This paper presents a novel approach for active gait trajectory planning in lower limb rehabilitation exoskeletons, specifically targeting hemiplegic patients. The proposed method integrates dynamic motion primitives (DMPs) and generalized regression neural networks (GRNN) to accurately simulate lower limb joint motion trajectories. Experimental results demonstrate the superiority of the GRNN-DMPs method over the standalone DMPs approach, as it generates joint trajectories with reduced error and enhanced precision. This approach holds great promise for active rehabilitation training with exoskeleton robots for lower limb rehabilitation.

Published: May 2024

A recognition method based on variational modal decomposition and random forest is proposed for fault diagnosis of gearbox vibration signals. Firstly, a vibration signal enhancement method based on VMD and kurtosis - permutation entropy reconstruction criterion is proposed for the problem of vibration signal noise interference, and a fault feature set construction method is proposed to help extract key fault information effectively; furthermore, by carrying out the simulation experiments such as missing tooth, gear root crack, spalling, chipping tip, and so on, we obtain the fault vibration signals and the feature set, and construct a random forest-based fault type recognition model based on random forest. The results show that the recognition accuracy of the proposed method reaches more than 90% in the test set, which can provide an effective way for the recognition of gearbox faults based on vibration monitoring.

Published: May 2024

The work space is one of the important indicators of the flexibility of the robot arm movement, it can be used to assess institutional performance. Therefore, the volume calculation and error analysis of the workspace are particularly important. To this end, this paper proposes a new algorithm for calculating the workspace volume, taking the holding arm of a self-designed laparoscopic surgical robot as the research object. First, the Monte Carlo method was used to solve the working space of the arm. Then, the volume of the regular workspace of the manipulator with unlimited joint angles is solved by the method in this paper and the geometric method, and the volume calculated by the geometric method is used as the standard value to analyze the error of the workspace volume solved by the method proposed in this paper. Finally, the optimal parameters are obtained through error analysis, and the working space volume of the robot arm that limits the joint angle is solved, which lays a theoretical foundation for subsequent robot arm configuration optimization.

Authors:   Azerbaijan State Oil and Industry University, Gurbanov Guseyn R. , Gasimzade Aysel V. ,   Azerbaijan State Oil and Industry University
Published: May 2024

In countries with developed oil industries, the primary objective is to effectively implement the demulsification of water-oil emulsions and provide corrosion protection for facilities during the preparation of heavy oils with stable emulsions for transportation. Consequently, the development of new multi-functional compositions to enhance the efficiency of the emulsion decomposition process and protect the internal surfaces of transport preparation facilities from corrosion remains a pertinent issue. The article presents the results of laboratory experiments on the demulsification of stable water-oil emulsions from the Muradkhanli field in Azerbaijan, which have a dilution rate of 41% (by mass) and provides satisfactory corrosion protection. For the first time, compositions comprising two new ingredients (Alkan-415+Gossypol resin in a 4:1 ratio (denoted as G-1) and Alkan-415+MARZA-1 in a 7:1 ratio (denoted as G-2)) were prepared under laboratory conditions, and their demulsification and corrosion protection effects in an acidic environment were studied. The demulsification process was conducted at temperatures of 50 and 600C for two hours. During the examination of the demulsification efficiency of the compositions, it was observed that the effectiveness of the reagents increased with higher concentrations. At temperatures of 50 and 600C, the most significant effects were observed at a concentration of 700 g/t for both compositions. At these temperatures, the residual water content due to the effect of the G-1 composition was 0.02% and 0.01%, and for the G-2 composition, it was 0.01% and 0.005%, respectively. Furthermore, the corrosion protection efficiency of both G-1 and G-2 compositions in an acidic environment was investigated. During the experiment, the highest effectiveness was observed at a concentration of 700 g/t for both compositions. At this concentration, the corrosion protection effect of the G-1 composition was 96%, while that of the G-2 composition was 98%. Thus, it was determined that, due to their multifunctionality and significant impact both in the decomposition of stable water-oil emulsions and in acidic environments, the optimal consumption rates of both compositions with new content are 700 g/t.

Authors: Golets O. Ia. , Movlaeva A. Z.
Published: May 2024

The purpose of the article is to define the historical and cultural differences of the two main currents of Islam. The study outlines the history of the division between Muslims into Sunnis and Shiites, defines the fundamental and inviolable principles of Islam for both currents and their main disagreements. The methodological basis of the research is the following methods: historical, which allows you to monitor the evolution of historical and cultural differences between the specified currents of Islam; logical, which contributes to the establishment of cause-and-effect relationships in the emergence of traffic flows; structural and functional, which makes it possible to show in detail the conceptual and categorical apparatus that researchers use when studying historical and cultural differences; comparative, which helps to find out how the value and geopolitical doctrines of Sunnis and Shiites differ. The presented research is interdisciplinary, based on the use of a combination of comparative-historical, phenomenological and hermeneutic-textological methodologies. Scientific novelty and relevance of the article are driven by the sharpness of interconfessional polemics, where the main issues of divergence between Sunnis and Shiites and their current state are often considered ideologically, with a noticeable bias towards one of the sides involved in the polemic. The authors of the article consciously engage materials from scholars of both currents, while maintaining research neutrality. Conclusions. Research findings indicate that the historical roots of differences between Sunnis and Shias in Islam trace back to the period following the death of Prophet Muhammad in 632 AD. Despite maintaining unity regarding the fundamental ideas and values of Islam, the main Islamic currents diverge on the following important issues: 1) the procedure by which Shias and Sunnis choose their religious leaders; 2) the influence of secular authority on the formation of religious hierarchy; 3) nuances of belief in the afterlife; 4) specifics of prayer organization; 5) interpretation of the imams’ theme; 6) differences in attitudes towards self-flagellation; 7) attitudes towards “temporary marriages”; 8) perspectives on the twelfth Imam Mahdi.

In the context of building a reputation of higher education institutions, one of the tools to increase their competitiveness is comprehensive support for the realization of the achievements of higher education students, in particular in the development of student sports. The field of sports is one of the most favorable in the context of building a personal and collective brand, personality growth, acquiring leadership qualities, popularizing traditions, values, and achieving communication goals of an educational or propaganda nature. Student sports, in turn, is a successful combination of ambitious intentions, building one's own trajectory of personal growth, opportunities not only to gain experience, knowledge, lay the foundations for a successful future, but also to form one's own brand, relying on the support of the institution (institution of higher education). The generation of such initiatives by a higher education institution is extremely relevant and justified, because the positive reputational and communication effect from such a symbiosis of parallel growth of the brand of an individual and the institution has a very longterm perspective. Mentioning the name of the university in an interview with athletes is one of the best elements of the PR activity of a higher education institution, because it can potentially attract the attention of an applicant who loves sports, but did not even know or considered the option of a particular higher education institution. The dynamism of increasing the role of self-realization is increasingly forcing applicants to search for a multifunctional innovative higher education institution. The demand for educational services is increasingly generating the relevance of building a strong reputation for the brand of an educational institution to attract students, increase competitiveness and maintain market positions. The modern information environment is maximally tuned to the strategy of differentiation, highlighting the positions of the leader among the main competitors. Entrants, as a specific segment of the target audience, actively respond in their requests not only to the quality of education, but also to the possibility of comprehensive development, in particular sports. The article deals with the issue of the impact of student achievements in sports on the popularity of the brand of a higher education institution.

The article is devoted to the study of theoretical and practical aspects of financial support for regional development in Ukraine. The importance of financial support for the development of the region is emphasized. It is noted that the formation of an effective system of financial support for regions plays a key role in creating the prerequisites for their socio-economic development, improving the level of satisfaction of citizens' interests, providing high-quality public services to the population, and coordinating the interests of the state and territorial communities. A model of financial support for regional development has been developed, which reflects the results of solving the tasks of the region's development at different levels (national, regional, local). The dynamics of revenues of the general fund of the State and local budgets of Ukraine (without transfers) in 2018-2023 were analyzed. The structure of local budget revenues by types of revenues was studied. It was established that tax revenues and official transfers took the main share in it, while non-tax revenues accounted for less than 6%. It was established that thanks to the rapid adaptation of enterprises, as well as state and local self-government bodies to the requirements of martial law, in 2023, the increase in revenues of the general fund of local budgets was ensured compared to 2022. It was noted that there was an excess of revenues to local budgets in Ukraine over their expenditures in 2023.

The article defines the socio-ecological aspects of innovation management in the sphere of subsoil use. It is noted that innovative management in the field of subsoil use is a separate branch of management and relevant activity, which arose and developed as a result of contradictory trends in the growth of subsoil use and limited opportunities for their effective involvement in economic processes. It is noted that the social aspects of innovative management in the sphere of subsoil use require an appropriate assessment to obtain an adequate answer to the question of the effectiveness of this type of management. It is determined that the ecological aspects of innovation management in the field of subsoil use are considered very important, since the modern competitive environment requires that ecological responsibility becomes the life philosophy of an economic entity and be the basis for building relationships with suppliers and consumers, as well as local communities. The principles and directions of improvement of innovation management on ecological issues in the field of subsoil use in Ukraine are determined. Attention was focused on ecological audit, which is a tool for determining how production activities meet national and international standards of sustainable development. It is noted that due to the full-scale war in Ukraine, the responsibility of each business entity for the preservation and restoration of the environment is growing. It is concluded that the socio-ecological aspects of innovative management in the sphere of subsoil use form the basis for the interest and combination of interests of the State, business and society to achieve a certain balance in matters of national security, meeting the needs of the population in public goods and ecological development on the basis of innovativeness, which in the future will create conditions for the formation and implementation of appropriate ecological strategies that will contribute to the development of education and science, social protection of the population, reducing the outflow of highly qualified workers, increasing innovative activity in the country’s economy, etc.

Post-war reconstruction of industry in Ukraine is impossible without the creation of appropriate conditions for the restoration of human resources potential, as well as ensuring its development and effective use. The foundation of the post-war recovery of the national economy should be modern industrial production based on the latest technological principles. The aim of the article is to substantiate the directions of strengthening the resilience of the human resources potential of industry as the basis for post-war reconstruction and renovation of the national economy. The article presents the author’s own definition of the resilience of human resources potential. The human resources potential of the industry has been studied by demographic, educational-qualification and motivational characteristics, identifying weaknesses as to the context of these components. Based on the analysis of the demographic component, a tendency of the national labor market to narrow due to a reduction in the demand and supply of labor force has been determined. A structural imbalance in the supply of labor force by age and gender has been revealed. In the study of the educational and qualification component, emphasis is placed on the growth of qualification horizontal and vertical gaps. The motivational component of the resilience of human resources potential is characterized by a decrease in the quality of working life and impoverishment of the population. Based on the results of the study, the author’s own approach to the development of directions for strengthening the resilience of the human resources potential of industry in the context of post-war economic recovery is proposed, taking into account its main components – demographic, educational, qualification, motivational. The expediency of restoring the national industrial sector of the economy on the basis of Industry 5.0 is substantiated. On the basis of the carried out research, directions for strengthening the resilience of human resources potential in terms of demographic, educational-qualification and motivational components are proposed and substantiated.
