Enhancement of Aeroengine Combustion Chamber Air Cooling Holes Design for Emission Reduction and Pattern Factor Control
Authors:   National Aerospace University Kharkiv Aviation Institute, Hajivand Masoud
Published: December 2024

The results of a comprehensive numerical analysis of temperature uniformity and NOx and CO emission predictions in an aeroengine annular combustor liner, conducted by geometrical modifications through design changes in primary cooling air, including effusion cooling holes, are shown in the paper. A total of five geometric configurations were studied using computational fluid dynamics (CFD) simulations in ANSYS CFX. The adopted combustion model was sort of a combination of the finite-rate (i.e., chemistry, chemical processes) and eddy dissipation model (FRC/EDM). Further, the combustion of liquid kerosene (C10H22) with air, subsequent to the evaporation of fuel droplets, was simulated, and the Rosin-Rammler droplet size distribution was used in spray modeling for accurate depiction of fuel atomization. Both thermal and prompt formation mechanisms of NOx were considered, while k-ε model for turbulence was adapted to capture the nature of emission. An annular combustion chamber of realistic dimensions with a double radial air swirler was modelled in 3D CAD to undertake this study for good, tangible results. Built contour plots allowed to analyze the temperature distribution and NOx concentration along the axis from the center of the injector. Charts on the pattern factor, temperature, and NOx and CO concentrations at the outlet of the combustor served as performance metrics. The simulation was implemented with a two-step chemical kinetics scheme for kerosene combustion with the P1 radiation model, which would give an accurate thermal radiation prediction. One of the major objectives of this research is to compare the CFD results at the combustor outlet with gas dynamic and thermodynamic calculations that have been carried out using AxStream software at the Department of Aeroengine Design, Kharkiv Aviation Institute. It is important to emphasize that the mean deviation of gas dynamic results obtained from AxStream and CFD simulation results was found to be insignificant, hence the CFD approach has been validated. The results testify that redesigning the combustor liner, especially in the design related to primary and effusion cooling holes, drastically reduced NOx and CO emissions. Also, these design modifications have helped in reducing or improving temperature uniformity at the combustor outlet, either way enhancing combustion efficiency and performance.

The combination of metal and composite in threaded couplings increases the reliability of the structure operating under conditions of intensive internal pressure. Strength analysis of threaded metal – composite couplings based on the application of modern finite element modeling methods at the stage of design documentation development allows to create more efficient structures that better meet the operational requirements. The strength of threaded couplings of cylindrical shells made of composite material and metal under the action of gas-dynamic internal pressure is analyzed in this paper. A methodology for numerical study of the problem in Ansys / Explicit Dynamics software package is proposed. Detailed modeling of threaded couplings is used. The developed model takes into account the following: dependence of material properties on ambient temperature; nonlinear relations between the components of stress and strain tensors in metal elements, orthotropic properties of composite materials; peculiarities of contact interaction in the zones of threaded couplings of prefabricated shell elements made of different materials. The stress state of a cylindrical structure with a central shell made of carbon fiber-reinforced plastic or fiberglass and with steel shells at the edges, loaded with gas-dynamic internal pressure with a maximum value of 20 MPa at a maximum ambient temperature of 100 °С was studied. It was obtained that plastic deformations are concentrated on the edges of the threaded couplings of steel shells. At the same time, the magnitude of plastic coupling deformations with the inner metal shell is an order of magnitude higher than for couplings with the outer metal shell. The magnitude of plastic deformations in couplings with an inner metal shell is twice less when using fiberglass than when using carbon fiber reinforced plastic. Localization of critical stresses was observed only in metal shells at threaded couplings. In this case, in the thread zone they are within the elasticity limits, and the stress state of the FRP shell is not critical. No local material failure was observed in the structure.

The problem of determining the optimal thermal power of the absorption bromide-lithium heat pump (AHP) with steam heating, integrated into the thermal scheme of the PT-60/70-130/13 steam turbine when operating in the mode with a slight opening of the rotary regulating diaphragm, was formulated and solved. The turbine plant released steam to consumers and provided heat according to the schedule of 150 / 70 ºС. The characteristics of AHP were modeled using approximate dependencies based on the characteristics of thermotransformer manufacturers. AHP was heated by steam from the production selection of the turbine after the steam screw machine installed for energy saving. The general optimization problem with the objective function of changing the monthly fuel consumption after the integration of AHP, based on the average monthly outdoor air temperature in the heating season in Ukraine, was divided into 6 auxiliary optimization problems. The control parameters of these problems were: thermal capacity of the AHP, steam pressure in the turbine condenser and at the inlet to the heat pump, steam pressure in the turbine headю These problems were solved by the coordinate descent method. Modes with steam consumption in the production selection of the turbine for the consumers were studied: 15, 30 and 45 t/h (with parameters: 1.296 MPa, 280 ºС) and mains water: 1600, 1650 and 1700 m3/h. Their feature is the provision of "useful" generation in volumes corresponding to the work of PT-60/70-130/13 without AHP with a closed rotary diaphragm. For all considered options of the turbine load, the optimal power of the integrated AHP is defined as 20 MW. During the heating period PT-60/70-130/13 with AHP 20 MW when operating in a mode close to the thermal load with the lower of the studied consumptions of production steam and mains water leads to savings of: fuel by ~3.5%, softened water by 8.5%, technical of water by 79.9%, as well as to a noticeable ecological effect due to the reduction of harmful emissions into the atmosphere. The preliminary payback period of AHP is close to 3 years. It is noted that the option of the integrated turbine with a partially open regulating diaphragm at the accepted prices for fuel and electricity loses in terms of economic indicators to the option with a closed diaphragm.
Adaptive Refinement of Segmented Object Contour Based on the Brightness of Neighboring Pixels Using the Ensemble Method
Authors:   Anatolii Pidhornyi Institute of Power Machines and Systems of NAS of Ukraine, Koniukhov Vladyslav D.
Published: December 2024

Improving the accuracy of computer vision algorithms plays a significant role in the tasks of medical image segmentation. After all, determining the boundaries of objects is a difficult task when using medical images, and especially X-ray images. The use of X-ray images in segmentation tasks is a complex process, since these images themselves can have a sufficient amount of noise and artifacts. Classical segmentation methods face significant challenges when segmenting X-ray images where there are objects with fuzzy boundaries. To solve such tasks, it is suggested to use segmentation with the help of machine learning, and to increase the accuracy of determining the boundaries of objects, it is necessary to use adaptive approaches. This paper proposes a new method to improve the accuracy of X-ray image segmentation, which analyzes the neighboring pixels of each contour element and adaptively reshapes it if necessary, and then combines all predictions using an ensemble method, which improves the previous version of the contour. The method was able to demonstrate an improvement in the quality of image segmentation on three datasets with different complexity of structures. Improvements in object boundary accuracy were obtained for all three sets.
DEVELOPING LANGUAGE ASSESSMENT LITERACY OF FILIPINO PRE-SERVICE TEACHERS: REFLECTIONS FROM A LANGUAGE ASSESSMENT COURSE
Authors: Alcazaren Holden Kenneth G.
Published: December 2024

Many educational and language scholars in the field have remarked the need to strengthen assessment and testing academic courses in the undergraduate teacher education programs, more specifically in highlighting the importance of language assessment literacy (LAL). With several findings indicating insufficient or impractical assessment components in many of these programs, academics and teachers alike agreed with the significance of developing pre-service teachers’ LAL to reinforce their theoretical knowledge and practical skills of assessment which would enable them to effectively construct and administer language assessments. In order to contribute to the discussions on LAL, this qualitative case study reports on the reflections made by the pre-service teachers (PSTs) of English language education (n=13) on their learning process during a university-based academic course on language test development in the Philippine setting. Guided by an assessment literacy framework, this study aims to explore PSTs’ LAL development and the contribution of the assessment course to this development. Findings revealed that the course produced extensive modifications in understanding the definition and principles of assessment, the various strategies and tools of assessment, and purposes and construction of language assessments. Additionally, the current research offers discussions into the influence of language assessment training on PSTs’ LAL development.

Authors: Chanwaiwit Panachanok , Mori Lynsey
Published: December 2024

This study examined the impact of a Collaborative Online International Learning (COIL) project on Thai Business English students’ awareness of intercultural communication and English as a Lingua Franca (ELF), along with their communication challenges and strategies. Data were collected through pre-post rating-scale questionnaires, open-ended questions, semi-structured interviews, and reflective journals. The study found that while the virtual exchange did not significantly affect the students’ overall intercultural and ELF awareness, it changed their attitudes toward ELF from negative to positive. The students reported increased confidence when communicating and presenting in English with a Thai accent and demonstrated a growing understanding of cultural differences in business communication. Despite this, the students identified several challenges, including language barriers, technical barriers, time zone differences, delayed responses, and non-compliance with established deadlines. To overcome these challenges, the students employed five effective communication strategies: developing cross-cultural communication skills, optimizing virtual meeting experiences, enhancing communication efficiency and collaboration, cultivating effective communication and relationship building, and practicing effective communication and conflict resolution. This study emphasizes the significance of virtual exchange for Business English students, as it enhances their intercultural communication skills and fosters acceptance of ELF, which is crucial for achieving success in today’s globalized business landscape.
UNDERSTANDING OVERREGULARIZATION PHENOMENON AMONG INDONESIAN CHILD L2 LEARNERS OF ENGLISH
Authors: Mahmud Masrizal , Erizar
Published: December 2024

Young learners are known to extend verb regularity further than it actually is. When it happens, this children’s overregularization phenomenon can be a result of several reasons: a failed linguistic development due to confusion between rules and memory, a lack of feedback from adults, and problems with cognitive development. The present study attempts to present some quantitative data that may relate to the overregularization issue and bring new findings to the existing debate in the area. The 12-month spontaneous spoken data were collected longitudinally from two Indonesian young learners of L2 English living in England. Utterances containing the use of regular verbs and plural -s were carefully compiled into a database and further classified according to the different types of regularities. From this data, a few overregularization instances were recorded from the research subjects who were between two and 10 years of age. Additionally, it was also apparent that the process of learning English consecutively or successively affected the way learners apply regular rules in obligatory spoken contexts. This study is expected to become a systematic analysis of the typologies of overregularization in Indonesian–English acquisition contexts, a particular nature of the Second Language Acquisition (SLA) issue that has rarely been investigated.
PLS-SEM MULTI GROUP ANALYSIS: UNCOVERING THE INTERPLAY OF FACTORS AFFECTING ACADEMIC WRITING SELF-EFFICACY OF EFL POSTGRADUATE STUDENTS
Authors: Prihandoko Lastika Ary , Nurkamto Joko , Djamika
Published: December 2024

This cross-sectional study investigates the factors influencing writing self-efficacy among EFL postgraduate students in Indonesia. It employs a quantitative analysis facilitated through partial least squares-structural equation modeling (PLS-SEM). The study engaged 150 master’s and doctoral EFL students as participants, examining the variables of writing enjoyment, research literacy, and teacher clarity and teacher immediacy in feedback, in relation to writing self-efficacy. The findings revealed that research literacy significantly improves writing self-efficacy, particularly among doctoral students. This demonstrates the crucial role of research literacy in building students’ confidence in their writing abilities. Furthermore, writing enjoyment was found to be a key factor in enhancing writing self-efficacy, especially for master’s students. This pinpoints the necessity to nurture joy in the writing process.
Teacher clarity was found to be essential for enhancing research literacy, whereas teacher immediacy had a lesser impact. This suggests a reduced reliance on teacher guidance during postgraduate studies. The study highlights the critical roles of research literacy and enjoyment in developing writing self-efficacy and illuminates the nuanced role of pedagogical strategies.  These insights are valuable for educational institutions and policy-makers in strengthening the EFL postgraduate learning environment. The differences observed between master’s and doctoral students call for further research to develop educational practices tailored to the different needs of these academic stages.

Authors: Syafi’i Ahmad , Munir Ahmad , Anam Syafi’ul , Suhartono Suhartono
Published: December 2024

Despite its critical importance in academic writing, effective feedback strategies in undergraduate thesis supervision remains under-researched. This case study aims to address this gap by examining the experiences of five English department students who completed their theses and the strategies their supervisors employed to facilitate timely completion. Utilizing semi-structured interviews and text analysis, the study addresses three key research questions: 1) how feedback is formulated; 2) what strategies are employed by supervisors; and 3) what are the students’ perception of the strategies. The findings indicate that most feedback was formulated as directive, and the supervisors’ strategies include timely, personalized feedback and additional supervision time.  The strategies help improve student engagement, motivation, and thesis outcomes. The students also positively perceived the supervisors’ strategies. This study contributes mainly by highlighting the role of emotional support in thesis supervision, the dominance of directive feedback in fostering timely completion, and the importance of personalized, timely feedback for student engagement. Additionally, it emphasizes that supervisors need to employ strategic, multifaceted approaches that combine academic guidance with emotional encouragement.
AGENCY AT WORK: A METAPHOR ANALYSIS OF LESSON PLANNING AMONG ENGLISH LANGUAGE TEACHERS IN THE PHILIPPINES
Authors: Valdez Paolo Nino , Lapinid Minie Rose , Chua Von Christopher
Published: December 2024

Lesson planning is a core skill teachers need to develop in implementing lessons effectively in the classroom. While metaphor research has been used in a range of contexts including in teacher education, metaphors associated with lesson planning among teachers in developing regions in the world remain underrepresented. Due to the importance of lesson planning in the implementation of the curriculum, investigating metaphors of lesson planning provides helpful insights on the beliefs of teachers in classroom practice resulting in effective instruction. This investigation sought to identify the metaphors Filipino teachers associate with lesson planning and their connections to teacher agency. This study, which is part of a larger investigation, examined metaphors from 73 English Language teacher-respondents in professional development workshops. The metaphorical conceptualization process employed in analyzing the data consists of three phases (1) validating and coding data, (2) summarizing and representing codes, and (3) identifying and describing categories. Results reveal eleven distinct conceptual categories, including perceptions of lesson planning as a project-like endeavor, an act of molding, and a form of creative expression, all of which highlight teacher agency in the teaching-learning process. These suggest that teachers take different roles in lesson planning depending on the nature of the subject matter, conditions they face in their work contexts, and their beliefs about teaching and learning. However, some teachers perceive lesson planning as routine and question its purpose, which poses challenges in designing effective professional development programs tailored to their needs.

Published: December 2024

This research investigates customer perceptions of savings instruments, focusing on fixed deposits
(FDs), which remain a popular investment choice for their safety and guaranteed returns. Despite competition from
other financial products like mutual funds and bonds, FDs continue to attract risk-averse investors. The study,
conducted for Shriram Finance, evaluates factors influencing consumer decisions, including safety, returns, liquidity,
and tax implications, while considering the demographic impact of age, income, and education.
Primary data were collected through structured surveys of 50 respondents across various demographics. The findings
reveal that while FDs are favoured for their security and simplicity, low returns and lack of flexibility deter some
investors. Awareness of advanced FD features such as tax-saving options remains limited, highlighting a need for better
customer education. Younger investors tend to diversify their portfolios, favouring higher-risk products, whereas older
and middle-income groups prioritize the stability of FDs.

A New Historicist Perspective on the Transformation in Perception of Cultural Heritage in Alice Walker’s Everyday Use
Authors: Ulucan Özlem
Published: December 2024

Alice Walker is one of the pioneering writers stressing the discrimination against African Americans living in the Southern part of America. Since her mother worked as a maid in the houses of the whites for more than four decades, Walker endured the hardships of unequal and inhumane attitudes of the whites against colored people. She participated in the Civil Rights Movement to protest black oppression and segregation. In her short story, Everyday Use, she carefully organizes the scenario to describe two subsequent generations of oppressed black women and the ways they react to the difficulties dictated to them. Like Walker’s mother, Mama internalizes the dictations of the whites and keeps a submissive lifestyle. However, she keeps her bond with her African roots by appreciating her cultural heritage. She is illiterate colored people are discouraged from education by white authorities. Unlike her submissive mother, Dee, goes to university and constructs a kind of awareness related to the equal rights of African Americans. While visiting her family, she prefers a pan-African point of view to stress her African roots, which was the motto of the Civil Rights Movement. She rejects the dictations and discrimination against the colored people. She demands some objects from her mother including the quilts containing some pieces of the clothes of their relatives, the churn top, and the dasher to show off in her house. This article aims to reveal the transformation of cultural heritage to superficial material culture for subsequent generations, represented by Mama and Dee by new historicist literary theory. This theory will be useful in shedding light on the historical background of the time implied in the story. The possible reasons for the change in the perception of cultural heritage will be analyzed by a new historicist reading of the story.
Understanding consumer perception and acceptance of AI art through eye tracking and Bidirectional Encoder Representations from Transformers-based sentiment analysis
Authors: Yu Tao , Xu Junping , Pan Younghwan
Published: December 2024

This study investigates public perception and acceptance of AI-generated art using an integrated system that merges eye-tracking methodologies with advanced bidirectional encoder representations from transformers (BERT)-based sentiment analysis. Eye-tracking methods systematically document the visual trajectories and fixation spots of consumers viewing AI-generated artworks, elucidating the inherent relationship between visual activity and perception. Thereafter, the BERT-based sentiment analysis algorithm extracts emotional responses and aesthetic assessments from numerous internet reviews, offering a robust instrument for evaluating public approval and aesthetic perception. The findings indicate that consumer perception of AI-generated art is markedly affected by visual attention behavior, whereas sentiment analysis uncovers substantial disparities in aesthetic assessments. This paper introduces enhancements to the BERT model via domain-specific pre-training and hyper- parameter optimization utilizing deep Gaussian processes and dynamic Bayesian optimization, resulting in substantial increases in classification accuracy and resilience. This study thoroughly examines the underlying mechanisms of public perception and assessment of AI-generated art, assesses the potential of these techniques for practical application in art creation and evaluation, and offers a novel perspective and scientific foundation for future research and application of AI art.

Authors: Şen Onur
Published: December 2024

In today's competitive and rapidly developing market, the importance of innovative products is increasing. Innovative products are needed to maintain growth and competitiveness. For this purpose, companies study on innovative applications and try new methods in product development processes. In this context, this study focuses on integrating the TRIZ tool into the product development process and producing creative solutions to the problems encountered during the design and development phase. And the benefit of TRIZ is discussed by conducting a case study involving the development of an innovative product. In the case study, the development process of the oil cap, which is located on the propeller shaft used to transmit torque and rotation in motor vehicles and whose main function is to provide sealing between the external environment and the internal volume of the propeller shaft, is discussed. The reason why the oil cap was chosen as a case study was the difficulty encountered in the design process, as the oil cap was expected to both provide sealing and allow air flow in the area where it was positioned. TRIZ methodology was successfully implemented to development of the oil cap. As a result of the study, an innovative product was developed, and validated by implementing tests. Thus, TRIZ's contribution to innovative product development was objectively demonstrated with a case study in which a commercialized product was developed. Besides, a practical guide based on real study, which designers could apply in innovative product development, was presented by this study.

Published: December 2024

The issue of risk assessment in road freight transport is currently a significant research gap, which is why the authors decided to conduct research in this field. The article presents a risk assessment model for the occurrence of undesirable events in the transport of oversized cargo. A critical review of the literature on the latest research on risk analysis and methods and tools for assessing the risk of road transport is presented. Based on the identification of the occurrence of various undesirable events, the authors proposed a general approach to the risk assessment model using a risk matrix. Elements of the transport network structure and parameterization of cargo and means of transport were identified and a record was provided. Significant limitations were indicated and a formal record of the probability of occurrence of undesirable situations was proposed. An important element of the article is the presentation of the procedure for calculating the probability of the effects of undesirable events and a practical example for real data for road transport of oversized cargo.

On Vladimir Solovyov and Russian Culture
Authors:   Kostroma State University, Edoshina I.A.
Published: December 2024

The article deals with the problem of personality’s influence on public consciousness and the consequences of this influence. According to the author of the article, examples of this kind of influence are found in European philosophy and are associated with the works of Plato, Descartes and Kant. It is further noted that in Russian culture (up until the 19th century), philosophical thought found not so much logical-abstract expression as figurative expression, which, to a large extent, the author of the article believes, is due to the specifics of Russia’s state development. This specificity is determined by the fact that the formation of statehood in Russia is closely connected with Orthodoxy and the church. The semantic dominants of this specificity, the forms of its existence and the consequences of its loss are revealed, one of the most dramatic of them is the formal observance of church dogmas. A number of examples from the lives of famous figures are given, testifying to how faith was perceived in society. The author of the article identifies two significant events in Russian culture of the 19th century, thanks to which Russian society began to “rediscover” faith as the foundation of life. One of these events is the painting by the artist A. Ivanov “The Appearance of Christ to the People”, and the other is the reading by Vl. Solovyov of public lectures “Readings on God-Manhood” in St. Petersburg in 1878. It is shown that these lectures had a strong influence on the minds of the philosopher’s contemporaries and served as a kind of catalyst for the creation of a number of important artistic and philosophical texts. As a result, Vl. Solovyov became not only the founder of Russian religious philosophy, but in the minds of his contemporaries he acquired the features of a prophet, which was largely facilitated by his way of life. In the end, the author of the article asserts that Russia’s turn to its roots will always be associated with the name of Vl. Solovyov as a unique Russian religious philosopher.

The problem of “Vladimir Solovyov and Russian symbolism” is considered in the article through the “prism” of the judgments of one of the last “Solovyov’s follower” of the twentieth century – Aleksey Fedorovich Losev (1893–1988). During the analysis, it was revealed that for an exhaustive understanding of Losev's judgments about symbolism and Solovyov in the late 1980s, when the thinker created the book “Vladimir Solovyov and his Time”, it is necessary to take into account the entire corpus of Losev's texts, primarily in the 1920s and 1930s (about Neoplatonism, name-glorification [imiaslavie], Dionysius the Areopagite, Nicholas of Cusa, etc.). It is shown that the development of Solovyov's legacy and Russian symbolism is conducted by Losev from the point of his own antinomic-dialectic system, which allows him to outline the dialectic of Solovyov's antinomic-synthetic symbolism more clearly and demonstrate both convergence and fundamental differences with contemporaries and followers – philosophers (Lev Lopatin, Eugene Trubetskoy, Ernest Radlov, Losev himself) and symbolists (Akim Volynsky, Vycheslav Ivanov, Dmitry Merezhkovsky, etc.). Losev's point of view on the “specificum” of Solovyov’s dialectic – his doctrine of Sophia and “all-unity”, mystical in spirit and symbolic in structure – is analyzed. The specificity of Losev’s approach to Russian Symbolism is determined by his dialectic of the symbol, which turns out to be the correlate by which Losev diagnoses the degree of closeness or distance to Soloviev’s ideas of specific Russian Symbolists. Losev's approach to the problem-thematic field associated with antinomianism can be used in modern practices of analyzing the role of antinomianism in the discourse of Russian symbolism in its two versions – literary and philosophical.

Philosophical heritage of V.S. Solovyov in the content of the new university course “Fundamentals of Russian Statehood”

Published: December 2024

The article is devoted to the explanation of the need to include V.S. Solovyov’s philosophical concepts in the content of the new course “Fundamentals of Russian Statehood” in connection with the high relevance of the philosophical heritage of V.S. Solovyov for the disclosure in this course of issues reflecting the specifics of the Russian worldview, which was formed on the basis of traditions Russian philosophical thought. The philosophy of all-unity of V.S. Solovyov has become one of the ideological doctrines of modern Russian civilization. It is also shown that in the popularization of the civilizational approach of N.Y. Danilevsky, it was V.S. Solovyov who played a special role. A point of view is being developed according to which, although V.S. Solovyov did not claim his own civilizational approach, in his works one can see a fully formed version of the civilizational approach, which is no less, and maybe even more, relevant than other versions for the new course “Fundamentals of Russian Statehood”. It is shown that the philosophical ideas of V.S. Solovyov, presented not only in his main philosophical works, but also in his poetic work, can provide invaluable help for the content of the course. The author gives arguments about the heritage of the great Russian philosopher containing many predictions regarding the challenges and threats that arise before Russian civilization in the 21st century.
