Surface Energy in the Processes of Disintegration of Solids
Authors: Fedorov V. T. , Kokoev M. N.
Published: October 2023

Objective. The purpose of the study is to experimentally measure the surface energy of solids during their grinding.

Method. The study is based on the use of methods for determining the surface tension of solids. At least 20-25% of all electricity produced in the world is spent on grinding materials in industry. When the resulting particles are reduced to tens of nanometers, the contribution of surface energy (st) to the grinding work becomes so large that it is difficult not to take it into account. Measuring the surface tension of liquids has long been proven. But measuring (st) of solids causes great difficulties. Currently, more than twenty methods for determining (st) are known.

Result. Based on the phenomenon of spontaneous bending of thin thread-like structures, a method for determining (st) has been developed. Examples are given in which (st) at the phase interface plays an important role in obtaining samples with a microstructure using the method of severe plastic deformation (SPD). To obtain fine metal powders, one of the variants of the SPD method has been proposed. A method has been found for the physical activation of aluminum granules, which increases the reaction rate of the metal in an aqueous environment by about a thousand times. This is necessary for the development of an anaerobic power plant capable of operating at great depths.

Conclusion. The new technology makes it possible to obtain high-purity, non-oxidized metal powders without toxic waste and emissions and with energy costs lower than in all known methods.

Conclusion. The design techniques outlined in the article ensure high seismic resistance of buildings and structures, which can be used in the practice of designing and constructing earthquake-resistant systems.
Narratives about Menopause
Authors: Hvas Lotte
Published: October 2023

Narratives and how women interpret their symptoms have always been a part of how menopause is experienced. Today, as women feel more accessible to talk about menopause, new narratives are being formed and negotiated - both to menopause and concerning women becoming older. These different narratives mirror the fact that the transitional phase differs from woman to woman and that some women experience many symptoms while others do not seem bothered at all. Some narratives underscore menopause as a transformative period, offering opportunities to adapt to new life roles and highlighting middle-aged and older women as individuals of competence, confidence, and experience. Other narratives center on describing bodily symptoms - primarily "classic symptoms," notably hot flushes, but also the broad array of physical and mental manifestations that may arise from one's early forties to late fifties. In this paper, I will, drawing on two decades of research on the topic, discuss examples from the ongoing debate about emerging new narratives: “The Competent Middle-Aged Woman,” “All Symptoms Are Menopausal Symptoms,” and “Menopause in the Workplace.” As medical society members who are in contact with women during this life phase, we need to support narratives that contribute to pride and strength while countering shame and embarrassment. Many women need more information about what is happening in their bodies, and some menopausal women need medical intervention. However, fostering healthy women’s trust in their bodies is equally important. Menopause is a natural part of a woman’s life, for better or worse, and not necessarily an issue that should be approached as a medical problem. It's crucial to maintain stories about competent middle-aged women being valuable assets in the workforce with excellent leadership potential instead of solely emphasizing the needs of those experiencing severe symptoms.
Topic based document modeling for information filtering
Authors: Nguyen Tran Diem Hanh
Published: October 2023

Information Filtering (IF), which has been popularly studied in recent years, is one of the areas that applies document retrieval techniques for dealing with the huge amount of information. In IF systems, modelling user’s interest and filtering relevant documents are major parts of the systems. Various approaches have been proposed for modelling the first component. In this study, we utilized a topic-modelling technique, Latent Dirichlet Topic Modelling, to model user’s interest for IFs. In particular, an extended model of it to represent user’s interest named Latent Dirichlet Topic Modelling with high Frequency Occurrences, shorted as LDA_HF, was proposed with the intention to enhance retrieving performance of IFs. The new model was then compared to the existing methods in modelling user’s interest such as BM25, pLSA, and LDA_IF over the big benchmark datasets, RCV1 and R8. The results of extensive experiments showed that the new proposed model outperformed all the state-of-the-art baseline models in user modelling such as BM25, pLSA and LDA_IF according to 4 major measurement metrics including Top20, B/P, MAP, and F1. Hence, the model LDA_HF promises one of the reliable methods of enhancing performance of IFs.
Analysis of printed document identification based on Deep Learning
Authors: Nguyen Dinh Thong , Nguyen Phu Quang , Mai Hoang Bao An
Published: October 2023

In this study, we investigate the effectiveness of ResNet, a deep neural network architecture, for a deep learning approach to address the problem of printed document identification. ResNet is known for its ability to handle the vanishing gradient problem and learn highly representative features. Multiple variations of ResNet have been applied, including ResNet50, ResNet101, and ResNet152, which provide the backbone architecture of our classification model and are trained on a comprehensive dataset of microscopic printed images containing some microscopic printing patterns from various source printers. We also incorporate Mix-up augmentation, a technique that generates virtual training samples by interpolating pairs of images and labels, to further enhance the performance and generalization capability of the model. The experimental results showed that ResNet101 and ResNet152 variants outperformed in accurately distinguishing printer sources based on microscopic printed patterns. We developed a mobile app to test the feasibility of our findings in practice. In conclusion, this study aims to lay the groundwork for creating a sufficiently pre-trained model with accurate performance of identification that can be deployed on mobile devices to detect the printed sources of documents.

Published: October 2023

The present study meticulously investigates optimization strategies for real-time sign language recognition (SLR) employing the MediaPipe framework. We introduce an innovative multi-modal methodology, amalgamating four distinct Long Short-Term Memory (LSTM) models dedicated to processing skeletal coordinates ascertained from the MediaPipe framework. Rigorous evaluations were executed on esteemed sign language datasets. Empirical findings underscore that the multi-modal approach significantly elevates the accuracy of the SLR model while preserving its real-time capabilities. In comparative analyses with prevalent MediaPipe-based models, our multi-modal strategy consistently manifested superior performance metrics. A distinguishing characteristic of this approach is its inherent adaptability, facilitating modifications within the LSTM layers, rendering it apt for a myriad of challenges and data typologies. Integrating the MediaPipe framework with real-time SLR markedly amplifies recognition precision, signifying a pivotal advancement in the discipline.

Authors: Phạm Thị Thu Hường , Phạm Thi Thu Hoa
Published: October 2023

Sự tách biệt xuất hiện trong số liệu theo mô hình hồi quy logistic có ảnh hưởng lớn đến giá trị ước lượng của các tham số hồi quy. Đối với thống kê cổ điển, ước lượng cực đại của hàm hợp lý sẽ không tồn tại khi số liệu xuất hiện sự tách biệt. Đối với thống kê Bayes, sự tồn tại của giá trị trung bình hàm hậu nghiệm phụ thuộc vào phân phối tiên nghiệm và kiểu dạng của số liệu. Do đó, trong nghiên cứu mô phỏng số liệu, việc kiểm soát xác suất xuất hiện của sự tách biệt là có ý nghĩa để nghiên cứu tác động của dạng số liệu này trong phân tích thống kê. Trong bài báo này, chúng tôi trình bày những thuật toán để mô phỏng số liệu theo mô hình hồi quy logistic mà sự xuất hiện tách biệt trong số liệu được kiểm soát với bất kỳ cỡ mẫu và số chiều của biến độc lập. Những thuật toán này được kiểm chứng có hiệu quả rất tốt qua kết quả mô phỏng.

Authors: Yuhui Xue
Published: October 2023

Maxine Hong Kingston is an American novelist of Chinese descent. Her masterpiece The Woman Warrior (1976) has attracted the attention of many critics, and there are a lot of relevant researches. There are various research directions, including cultural conflict, narrative perspective, feminism and archetypal interpretation. However, there are few studies on the rewriting of the two historical stories of Hua Mulan and Ts’ ai Yen in the works. Starting from two historical stories, this article will study the adaptation and meaning of the novel by the method of intensive reading and analysis of the text. In the rewriting of Mulan's story, the protagonist who grew up under the background of dual culture and life imagined a female image who pursued freedom, equality and realized her own value, which is the rewritten image of Mulan. The rewriting of Ts' ai Yen's story is used to show the dilemma experienced by the protagonist and the final solution of the problem. In rewriting the stories of historical figures, the work shows the struggle and exploration of Chinese Americans who try to establish their cultural identity between Chinese and American dual cultures.

Sociedad civil y comunidades. Una relación pensada desde Bolivia
Authors: Tapia Mealla Luis , Salazar Lohman Huáscar
Published: October 2023

Una de las apariencias fundantes de la modernidad capitalista es la que presenta a la política que emana en torno al Estado como aquella que es universal y totalizante. En este texto se presenta una reflexión sobre la relación entre sociedad civil y comunidad, elaborando un argumento que refiere a que lo social no deriva necesariamente del Estado y que la comunidad no es una parte de la sociedad civil –la cual es un desdoblamiento de la sociedad moderna–, sino que es una sociedad en sí misma, con formas propias para la producción de decisiones políticas, aunque en situación de subalternidad. Sin embargo, en el vínculo entre sociedad civil y comunidad emerge un conjunto de organizaciones bisagra que son las que permiten la interacción de ambas formas societales. A partir de esta reflexión, se presenta como ejemplo el caso de la formación de comunidades en la región del Norte Amazónico de Bolivia, una experiencia particular de producción de formas comunitarias para la gestión de la vida social.

Esta revisión muestra la estructura y biogénesis del flagelo bacteriano y su diversidad estructural en numerosos modelos bacterianos. Se expone, cómo a partir de un núcleo estructural flagelar conservado (NEFC), se han diversificado las estructuras que modifican su capacidad y función. Esta variabilidad se sabe, participa en la habilidad de adaptación de cada especie a un nicho específico. El motor flagelar bacteriano es una estructura compleja constituida por un rotor y un estator, los cuales se encuentran embebidos en la envoltura celular. La incorporación de nuevos componentes, que contribuyen a su funcionamiento, incluyen la presencia de anillos o discos adicionales a los presentes en el NEFC, cubriendo o interactuando con el cuerpo basal y el estator, lo que permite una mayor eficiencia y velocidad de rotación al favorecer el reclutamiento de un mayor número de estatores, o que permiten la estabilización de estos al rotor. Además, podemos encontrar ganchos más robustos o filamentos con flagelinas modificadas que presentan propiedades enzimáticas. El aumento de los modelos bacterianos estudiados junto con el avance de las técnicas de visualización como la crio-microscopía, han permitido describir la gran riqueza existente en las variaciones de la arquitectura flagelar lo que ha llevado a un cambio de paradigma al lograr entender algunos de los procesos que permiten el ensamblaje y función del motor flagelar. Todo lo mencionado evidencia el momento de rápido progreso que el campo de estudio del flagelo bacteriano muestra recientemente.

Los significados editoriales del Boom latinoamericano: Skinner y la historia intelectual latinoamericana
Authors: Sáizar de la Fuente Consuelo
Published: October 2023

Este artículo aborda el Boom latinoamericano como proceso editorial de profesionalización y globalización de las novelas de la región en los años sesenta del siglo XX. Se alude a la teoría y metodología de Quentin Skinner para el estudio del significado y comprensión de las ideas. Se argumenta que hubo un proceso simultáneo de internacionalización y de consolidación profesional de cuatro escritores clave del Boom (Julio Cortázar, Carlos Fuentes, Gabriel García Márquez y Mario Vargas Llosa) y que dicho proceso implicó que el fenómeno tuviese a la industria editorial española como base, con el editor Carlos Barral y la pionera agente literaria Carmen Balcells, quienes supieron aprovechar el significativo capital cultural y el ambiente propicio para difundir las novelas latinoamericanas en el mundo de habla española y la promoción de traducciones para otros públicos lectores. Así, se explora la adaptación y extensión de planteamientos de Skinner al contexto latinoamericano contemporáneo para la producción de historia, se ubica al Boom como parte integral de la cuarta fase de la historia intelectual latinoamericana, según Juan Marichal, y se aborda la faceta de los significados editoriales de la globalización de la novela de la región para contribuir al estudio del Boom latinoamericano.
Opinion Leadership in Clothing Fashions with Specific Reference to Student Community: An Analysis
Authors: Bhardwaj Harshit , Rajyalakshmi Dr.
Published: October 2023

Abstract: This study investigates the role of fashion opinion leaders and followers in information seeking within the clothing fashion domain. The research focuses on examining the number, frequency, type, and variety of fashion information sources used by leaders and followers during different stages of the fashion adoption process, namely awareness, comprehension, and legitimation. However, opinion leaders demonstrated a higher propensity to consult a greater number of sources and do so more frequently compared to followers. Moreover, both leaders and followers recognized marketer-dominated sources as influential in creating awareness of new clothing styles. Notably, during the comprehension stage, the most significant sources differed between the two groups, with opinion leaders relying more on marketer-dominated sources, while followers leaned towards consumer-dominated sources. Additionally, the research examined demographic characteristics of the respondents but found no significant differentiation between opinion leaders and followers based on these factors. This suggests that the distinction between leaders and followers in fashion opinion is not necessarily driven by demographic attributes
Dye-Based Bifacial Silicon Solar Cell Fabrication
Authors: Jalil Muhammad Arif Bin
Published: October 2023

Abstract: Solar photovoltaic (PV) is a well-known energy harvesting technology or a semiconductor device that is used in generating electricity from the sunlight via the conversion process. Currently, solar photovoltaic is increasingly growing as an alternative renewable energy in conventional power generation. There are two types of solar photovoltaic cells which are monofacial and bifacial solar cells. The difference between these two solar cells is, monofacial, only generate electricity when the light touches the front side whereas the bifacial solar cell does generate electricity from both the front and rear side. In this research project, the bifacial solar cell is used to fulfil the purpose of increasing the power conversion efficiency as it can generate power from both surfaces. The bifacial is known to produce more energy up to 27 % than the monofacial according to the claims of some manufacturers. The base of this bifacial solar cell is silicon. Silicon purely contains an atomic structure that makes it suitable and more stable to be the raw material of a semiconductor due to its behaviour to block and conduct electricity. This is mainly due to silicon having the conductive properties of metal as well as an insulator. The silicon wafer will undergo the whole fabrication process to become the semiconductor devices. However, there is a problem encountered with the PV cell when it is consistently improving and when analysing the potential areas: on the power conversion efficiency. This is one of the challenges that can be solved with a strategy to increase the availability of the photon trapping of the solar cell which we called as the surface passivation of the bifacial solar cell. Surface passivation is a way that can minimise the recombination loss and efficiency loss while enhancing the optical path length of the solar cell on the photon absorption. It is the most significant step to increase the efficiency of the bifacial solar cell which is also known as an anti-reflection coating (ARC) using dye-based coating techniques. The development of the anti-reflection (ARC) lays on the fabrication techniques, optical performance and the light trapping structures as well as their impact on its efficiency

Experiment of Fuzzy Logic on Game System
Authors: Nayak Mohit Raj , Simha J. B.
Published: October 2023

Abstract: Applications of fuzzy logic in game creation have proven useful, especially when it comes to modelling the behavior of non-player characters (NPCs) in video games. NPC behavior in video games has historically been governed by strict rule-based systems or scripted sequences, which frequently led to restricted and predictable interactions. On the other hand, fuzzy logic adds a degree of flexibility and ambiguity to the decision-making processes of NPCs. By improving the naturalness, adaptability, and emotional resonance of NPC behavior, fuzzy logic may greatly enhance player experiences in games. It provides players with progressively more engaging and dynamic gaming experiences as it continues to be incorporated into game production, opening up new possibilities for interactive narrative, gaming, and immersive virtual worlds. Based on Utku Kose's article, "Developing a Fuzzy Logic Based Game System," I have investigated the use of fuzzy logic in gaming contexts for NPC decision-making in this study.

Published: October 2023

Students' environmental knowledge and sustainability awareness are important competencies to prepare them to face global environmental challenges. The study aimed to evaluate the gender difference and correlation between students’ environmental knowledge, sustainability awareness, and sustainability practice frequency after Education for Sustainable Development (ESD) in Biology lesson. This study uses a quantitative research design with a one-group pretest posttest design using cognitive tests and a self-administered survey. The participants were year X students in one of the schools in Indonesia, during 2022/2023 academic year, including 114 students (M=54, F=60). The result found that although Indonesian high school students generally have high overall environmental knowledge students have low knowledge of global warming. Students have a high sustainability awareness and a high average frequency of practicing sustainability. Secondly, this research found that gender differences exist where female has significantly higher environmental knowledge than male students. Female students also have higher consciousness in all specific domains of sustainability, and they have statistically higher sustainability behavior than males. Environmental knowledge has a statistically moderately positive correlation with the frequency of sustainability practices. Environmental knowledge has a weak correlation with sustainability awareness. The frequency of sustainability practices has low correlation with sustainability awareness.
