Properties of the forgotten index in bipolar fuzzy graphs and applications.

Topological indices are the numbers that remain constant under graph automorphism. Topological indices describe a network's connectivity, structure, and topological characteristics. These indices have many applications in crisp graphs. However, in many cases, it is observed that some situations can't be described using the idea of crisp graphs. So, to overcome this issue, the need to define topological indices for fuzzy and bipolar fuzzy graphs arises. The F-index, or the Forgotten Index, is a significant topological index. A bipolar fuzzy graph with two opposite-sided opinions of both the edges and vertices measures the impreciseness or uncertainties of the edges and vertices along the positive and negative sides. In this article, we have presented the Forgotten Index for bipolar fuzzy graphs. Then, we have proved some theorems regarding the F-index of numerous types of bipolar fuzzy graphs, such as regular bipolar fuzzy graphs, complete bipolar fuzzy graphs, etc., the bounds of the F-index in bipolar fuzzy graphs, and the relationships of the F-index with other topological indices in bipolar fuzzy graphs. We have applied the proposed topological index, the F-index for bipolar fuzzy graphs, to matrimonial websites to find potential life partners based on compatibility and discussed the application of the Forgotten Index in gene regulatory networks.

NEW ASPECTS OF CORE MICROTOMOGRAPHY

Compared to many other technologies of laboratory studies of core samples, the modern «digital core» technology is a rather young scientific and industrial direction, but for decades it has attracted close attention of a wide range of scientists and specialists of the oil and gas industry (geologists, sedimentologists, lithologists, geophysicists, developers, geological modelers, hydrodynamicists, physicists). For many specialists of practical sphere new methodical techniques and methods of such researches remain little known. If earlier computer X-ray microtomographs in the Russian Federation were the prerogative of only academic structures or service organizations, nowadays many subsoil users have started to equip their own laboratory and research centers with the corresponding specialized equipment, understanding that without these data it is hardly possible to build high-quality geological, petrophysical, tectonic-physical, rheological, hydrodynamic and geological-field models of the studied sediments, as well as to prepare progragmatic models of the studied sediments. In this article the authors made an attempt to study and analyze the current state of development of «digital core» technology.Using extensive factual material the accumulated experience of special studies in the field of full-size core tomography is summarized, estimates of absolute permeability of low-permeability complex sediments are made, results of studying cores in frozen and unfrozen state are given, detailed analysis of fracturing at different stages of sample preparation and ongoing studies is carried out, and specific problems for which a solution using the technology is expected in the near future are formulated In this article the positive and negative sides of poroset and direct methods of modeling of filtration properties by digital core model are studied. Particular attention is paid to the need for large-scale studies to obtain statistically reliable data samples, which can be used to select the most qualitative methods of research and application of algorithms for processing of initial geological and geophysical information.

Elderly Health Care Voucher Scheme in Hong Kong: needs assessment and an evaluation of outcomes

ABSTRACT Elderly Health Care Voucher Scheme represents a form of demand-side subsidy given to the elders to choose a spectrum of medical services in the private medical sector. The current paper aims at (a) conducting a needs assessment of the scheme with an analytical framework of the Four A 's approach (i.e., availability, awareness, accessibility, and acceptance regarding a social program) and (b) evaluating whether the outcome measures of the scheme (i.e., the use of private healthcare services, the use of primary care and the empowerment of the elders in the choice of services) were achieved. The needs assessment concludes that the utilization rate of the elders, awareness and satisfaction rate are high. The positive sides concluded from the needs assessment, however, failed to turn into the fulfillment of outcome measures due to the structural barriers. Recommendations at short-term, medium-term and long-term are made.

Student Motivation and Effectiveness of Online Learning: A Qualitative Perspective

Even though the COVID-19 era has passed 4 years ago, online learning is still implemented as a hybrid or a necessity, especially in high-level health education. Online learning has many positive sides, such as being able to learn anywhere, cost-effective, and being more time flexible, making online learning considered an efficient learning method compared to face-to-face. As a result, in the current situation (post-pandemic) online learning is still valid even though it is sometimes interspersed with offline learning. This research aims to determine the obstacles faced by students in conducting online learning and their impact on learning motivation through interviews. Apart from that, it also aims to study the effectiveness of online learning through observation. Based on the research objectives, observations and interviews are needed to provide a deeper understanding, and provide an idea of whether there is and how much effectiveness and motivation to learn in online learning. It is expected that this research can also provide updated data that can be useful not only for researchers but also for readers. In addition, it is envisaged that this study would deepen the understanding of the efficiency of online learning and will motivate students. Keywords: student motivation, learning effectiveness online learning

Acoustic field and power matching mechanism in looped heat-driven thermoacoustic refrigerators

Heat-driven thermoacoustic refrigerators (HDTRs) offer great potential for the sustainable energy development due to their environmental friendliness, high reliability, and promising efficiency. However, there remains a gap in the comprehensive study and understanding of their acoustic matching and energy conversion mechanisms, the resolution of which would facilitate the development of more efficient HDTRs. This work employs Sage to model fundamental thermoacoustic engines and coolers, aiming to explore the effects of temperature and acoustic fields on their performance. It highlights the acoustic and temperature-matching patterns of looped HDTRs operating at room temperature range. The optimal impedance phase for the thermoacoustic engine and cooler is located on the negative and positive sides, respectively, of the pure traveling wave zero-phase point. The thermal buffer tube provides better phase matching between the engine outlet and cooler inlet compared to the resonator tube. Focusing on a single-unit HDTR system, the present study evaluates the steady-state performance and acoustic distribution analysis for systems different connections and couplings. Additionally, it compares looped HDTRs with various coupling configurations from the literature, further confirming the superior refrigeration performance of directly coupled systems. These findings provide valuable insights for developing more efficient thermoacoustic refrigerators, contributing to sustainable energy advancement.

Homework - Necessity or Myth?

Throughout generations a question has been posed: do students benefit from writing homework and does homework fulfill its purpose? The debate about the usefulness of homework causes many doubts in the educational public. Learning outcomes and the importance of homework are different today than twenty or more years ago. Contemporary students are not very interested in this type of activity, showing a high degree of non-independence in performing tasks outside the school environment. The author discusses the expediency of writing homework and its impact on students' learning achievements in class. Accordingly, the author examines the positive and negative sides of this extracurricular activity. This article was created based on the analysis of previous research and knowledge about this subject. Some Croatian and Slovenian didacticists believe that homework should not be abolished, but it should be functional, comprising of various exercises aimed at encouraging students to be active. Tasks are justified if they expand the possibility of learning and serve to develop students' abilities and skills. The author states that homework is necessary in the mother tongue teaching, especially at the initial level of primary school education. The teacher must control the quality and quantity of the homework, taking into account the time the student needs to complete it and the type of goals he wants to achieve in relation to the linguistic and literary material. The article offers the examples of homework in the fields of mother tongue, literature, written expression, reading and media culture. Modern technology offers numerous possibilities for creating creative homework.

Effects of limiting current density and current step rate on microstructure and hardness of flash sintered MgAl2O4 ceramics

This study investigates the effects of limiting current density and current step rate on the microstructure and hardness of current-step flash-sintered (CS-FS) disc-shaped MgAl2O4 ceramics. The results indicated that, unlike conventional flash sintering, the temperature of the sample during the current-step flash started at a lower initial value and subsequently increased gradually. Furthermore, the differences in oxygen vacancies between the positive and negative sides of the CS-FS-ed MgAl2O4 ceramics were significantly reduced. This led to the CS-FS samples exhibiting higher relative density, finer grain size, a more uniform microstructure, and increased hardness. The homogeneous microstructure resulted in consistent hardness across both sides of each CS-FS-ed sample. Additionally, as the limiting current density increased, the grain sizes near the positive and negative sides gradually enlarged, while the relative density initially increased before decreasing. A similar trend was observed when the current step rate decreased.

Stress, Adaptation and Causal Pathways to Mental Health Disparities

Abstract The present article addresses the evolutionary dimension of stress process, specifically focusing on the conceptual division into ontologically ‘ancient’ and ‘modern’ stressors. A study conducted in Kyiv, Ukraine (n = 208) in 2020 examined the relationships between both stressor types and measures of short- and long-term mental health outcomes for both positive and negative sides of mental health spectrum. Three empirical observations are noted. (1) Modern stressors but not ancient stressors had a significant effect on depression measure, despite being rated as less severe stressors by the participants. (2) Neither type of stressors was found to affect flourishing. (3) High current socioeconomic status and high degree of social cohesion attenuated the effects of modern stressors (but not that of ancient stressors) on depression; at the same time, socioeconomic status did not diminish the participants’ perceived stress levels. The theoretical implications for the adaptationist perspective on stress, mental health and health disparities are discussed.

Hybrid Neuro-Fuzzy Based Improved Control Design of Electro-Pneumatic Clutch Actuation Control System for Heavy Duty Vehicles

The application of hybrid Neuro-Fuzzy principles of clutch actuation control in enhancing the performance of electro-pneumatic clutch actuation system for heavy duty vehicles is the aim of this presentation. Neuro-Fuzzy is a hybrid design that accommodates the principles of fuzzy Logic and Neural Network in a manner that take advantage of their positive sides. The inability of some heavy-duty vehicles to operate optimally on hilly terrains and which often results in road mishaps are traceable to the inadequacies in conventional clutch actuation control mechanisms. These conventional actuation control techniques provide for routine calibration of clutch actuators after maintenance. Often times, this important requirement of calibration is neglected with attendant ugly consequences. To stem this tide of manual calibration and its obvious defects, an intelligent method of clutch actuation modelled in a hybrid Neuro-Fuzzy control is implemented. Conventional data obtained for errors, speed, torque and power from Mercedes Benz Actros Truck model MP 2, 2031 provided the reference points. These data were embedded into a Simulink block and cascaded into a designed Neuro-Fuzzy Simulink model. Both conventional and Neuro-Fuzzy Simulink model controllers were also simulated. Different percentages of improvements were recorded for piston error, angular speed, engine torque and power respectively. The level and percentage of improvements stood at 0.4821mm or 33.04% decrease for error, increases of 334.1 RPM or 33% for angular speed, 0.0594NM or 33.26% for torque and 2.79W or 16.53% for power respectively.

PERFORMING ACTIVITY AS A MEANS OF DEVELOPMENT OF MUSICAL THINKING

This article deals with the problem of developing the creative independence of a musician-performer in the process of interpreting the composer’s image of a musical work. The author proves that the psychotechnical approach to work on a composition prevails in modern music pedagogy, whereas the approach based on the theory of psychophysical unity is much more effective. A comparison of the two approaches, their positive and negative sides is given. The conclusion of the article is understanding of the need for a creative dialogue between the composer and the performer of a musical text, which also implies unconditional command of the musical “language”, subordinate to mastery of musical “speech”.

An Empirical Evaluation of Eritrean Expatriates in the USA

The number of Eritreans leaving Eritrea in search of a better life and future in foreign countries has increased in the past years. As a consequence of the conflict that has erupted between Ethiopia and Eritrea, Eritrean communities in the USA have established organizations and consortiums in order to encourage their members to work together towards common goals. The aim of this research study is to investigate and evaluate the positive and negative sides of being a first-generation Eritrean expatriate in the USA through empirical qualitative interviews with 20 respondents. The study begins with the backstory of the respondents regarding the reasons why they moved to the USA in the first place. It then goes on to examine the respondents' acculturation process in terms of Eritrean culture and American culture. Furthermore, the results from the interviews are analyzed and evaluated in terms of supporting and opposing arguments, as well as implications, applications, and recommendations for future similar research projects. The research study provides insight into the experiences of Eritrean expatriates in the USA, making it useful for anyone who has an interest in the lives of expatriates. Additionally, it is believed that the findings of this research project will be useful for organizations that concern themselves with the welfare of Eritrean communities abroad.

A critical review of domestic and foreign methodological aspects of financial strategies formation using a matrix method in modern realities

Subject. The article discusses financial strategies in the corporate finance management system based on a matrix approach. Objectives. The purpose is, after the analysis of existing financial models in economics that are based on the matrix approach, to identify positive and negative sides of each toolkit, while offering criteria for their comparison, formulated on regional, sectoral, and behavioral aspects. Methods. The study employs theoretical (analysis, synthesis, modeling, systematization) and empirical (comparison, classification by characteristics, mathematization) methods of scientific research. Results. I analyzed economic scientific literature concerning domestic and foreign methods of corporate finance management, defined the terms "financial model" and "financial matrix", compared domestic and foreign instruments, developed criteria for evaluating the existing techniques. The criteria enabled to reveal advantages and disadvantages of the matrix strategies mentioned above. Conclusions. A specific feature of domestic matrix methods is diversification. Moreover, almost all existing financial models are marked by universality: industry differences are ignored. However, each methodological toolkit has its "pros" and "cons", various indicators and financial strategies. At present, there is a need to form a new methodological technique based on the matrix approach. This toolkit can be presented in the form of a financial model characterized by precision and optimality, and would also consider such parameters as industry and regional specifics.

Language Learning Through Zoom

Attributable to the COVID pandemic, Zoom has become one of most widely used digital tools for online interaction. Schools and universities had to transition to wholly online teaching, and Zoom was one of the platforms used for real-time sessions. Therefore, it is necessary to investigate students' experiences of using tools like Zoom to see the positive and negative sides of videoconferencing for language learning. Students' and teachers' digital competence is an important factor that impacts online learning, and therefore students' experiences are analyzed in relation to the TPACK framework, which looks at teachers' digital competences and the intersections between their technological, pedagogical, and content knowledge (TPACK). It is found that especially the intersection between technological and pedagogical competences is sometimes lacking among teachers and is identified as the cause of a lot of negative experiences. Thus, the conclusion of this study is that such competences need to be developed by teachers.

Comparative Analysis: Machine vs Human Translation of Educational Scientific Texts. Challenges and Solutions

Introduction. The purpose of this article is to analyze the features of identity formation and identification processes in postmodern society and in digital society. The article explores various approaches to the concept of «identity» within the framework of socio-humanitarian theories. The interrelation of real and virtual identity, the emergence of new forms and models of identity are considered. Two approaches to the analysis of identity in a digital society are analyzed and compared: digital optimism and digital pessimism.Methodology and sources. The article uses a comparative analysis of various theoretical approaches to identity formation. An interdisciplinary approach is used to understand the features of identity in the era of digitalization. As the main sources for the study of the phenomenon of identity there were used works of classics of sociology and psychology E. Erickson, J.G. Meade, E. Durkheim, as well as studies of representatives of modern philosophical and sociological theories Z. Bauman, A. Giddens, S. Turkle, A.A. Lisenkova, T.G. Leshkevich.Results and discussion. It is shown that in postmodern society, identity is characterized by the processes of individualization, fragmentation and the absence of a single cultural center. In a digital society, along with the processes of individualization, there are processes of standardization and unification of person. It is concluded that in a digital society, identity has positive and negative sides. On the one hand, there is a positive vector for the use of online communications, network interaction of people, which destroys spatial and temporal boundaries, as well as social barriers. On the other hand, new types of virtual identity are being formed, challenging a person's own identity.Conclusion. It is concluded that the digital society changes human identity, identification practices and strategies. The consequence of these processes is the formation of a person fused with digital technologies, which leads to the transformation of the social order, social norms and society as a whole.
