Application of human-computer interaction technology integrating biomimetic vision system in animation design with a biomechanical perspective
Authors: Han Jing
Published: December 2024

The combination of Human-Computer Interaction (HCI) technology with biomimetic vision systems has transformational potential in animation design, particularly by incorporating biomechanical principles to create immersive and interactive experiences. Traditional animation approaches frequently lack sensitivity to real-time human motions, which can restrict engagement and realism. This study addresses this constraint by creating a framework that uses Virtual Reality (VR) and Augmented Reality (AR) to generate dynamic settings that include a variety of human activities, informed by biomechanical analysis. A biomimetic vision system is used to record these motions with wearable sensors, allowing for precise monitoring of user activity while considering biomechanical factors such as joint angles, force distribution, and movement patterns. The recorded data is preprocessed using Z-score normalization methods and extracted using Principal Component Analysis (PCA). This study proposed an Egyptian Vulture optimized Adjustable Long Short-Term Memory Network (EVO-ALSTM) technique for motion classification, specifically tailored to recognize biomechanical characteristics of human movements. Results demonstrate a significant improvement in precision (93%), F1-score (91%), accuracy (95%), and recall (90%) for the motion recognition system, highlighting the effectiveness of biomechanical insights in enhancing animation design. The findings indicate that integrating real-time biomechanical data into the animation process leads to more engaging and realistic user experiences. This study not only advances the subject of HCI but also provides the framework for future investigations into sophisticated animation technologies that use biomimetic and biomechanical systems.
Application of biomechanical insights in the “Second Classroom Report Card” in mental health education for college students in the big data era
Authors: Peng Yiwen , Jia Xiaodong
Published: December 2024

The construction of a comprehensive, reasonable, and scientific evaluation system for the mental health level of college students is a prerequisite for a high-quality mental health education. With the arrival of the big data era and the promotion and implementation of the “Second Classroom Report Card” system in colleges and universities nationwide, a new approach has been provided for the evaluation of college students’ mental health level. The article deeply analyzes the main problems in traditional evaluation of college students’ mental health level and explores how big data can enhance these evaluations. Furthermore, we introduce the biomechanical aspects that influence mental health, such as the impact of physical activity on psychological well-being and the role of movement patterns in stress reduction. Empirical analysis, it is proved that there is a strong correlation between the scores of college students’ second classroom course projects—often involving physical activities—and their mental health level. By integrating biomechanical principles, we can better understand the physical factors that contribute to mental health, thereby enriching the evaluation framework. The establishment of “big data + biomechanical insights + mental health level” evaluation system based on the “Second Classroom Report Card” has improved the timeliness, pertinence, and scientificity of mental health education work in colleges and universities. This approach not only facilitates a more holistic understanding of student well-being but also promotes the importance of physical health in maintaining mental wellness.

The findings of this research have implications for fire safety engineering and risk assessment. A more accurate understanding of the flame behavior can lead to the development of improved fire detection and suppression systems. Furthermore, the numerical modeling approach can be extended to investigate a wide range of fire scenarios providing valuable data for the validation and refinement of fire models. This work presents a numerical study of turbulent diffusion flames on a vertical polymethyl methacrylate (PMMA) surface using the Fire Dynamics Simulator (FDS) employing LES method for turbulent transfer. LES method is used with Deardoff model for subgrid-scale viscosity; reactant concentrations are determined using the generalized reaction coordinate within the framework of the Eddy Dissipation Concept (EDC) model. Methylmethacrylate (product of PMMA pyrolysis) is assigned as the gaseous fuel component of gas-phase combustion reaction with corresponding values of molar weight and heat release. Series of numerical experiments were performed for different heights of the burning surface (5 cm, 20 cm, 50 cm, and 1 m) to investigate the flame height dependence on the pyrolysis zone size. Based on the calculated temperature fields, the flame height dependence on the pyrolysis zone size on the vertical surface was determined. The results of the simulations demonstrated good agreement with existing experimental and theoretical data.

Authors:   Udmurt Federal Research Center UB RAS, Karskanov Sergey A.
Published: December 2024

A numerical experiment was carried out based on direct numerical simulation. The problem of the viscous gas flow through the tapered conical nozzle was solved by integrating the Navier-Stokes equations. The integration of the Navier-Stokes equations was carried out using high-order approximation algorithms on a multiprocessor cluster "Uran". The Lighthill stress tensor was used to describe acoustic interactions in a pulsating medium. The graphs of the Laithill tensor component fluctuations are given. In the middle of the nozzle and at the outlet, the values of the tensor components are comparable in absolute value, i.e., they are within the same order of magnitude. With an increase in the constriction angle, the amplitude of the oscillations of the component values decreases. Based on the discrete Fourier transform, the frequency spectra were constructed, at which the components of the Lighthill tensor oscillated in nozzles with different constriction angles. It is shown that at the point behind the step, the frequency distribution is more uniform. The oscillation amplitudes at all points under consideration decrease with increasing conicity angle.

A comparative study and analysis of the physical and mechanical properties of the surface layers of multilayer Ni/Al films on the surface of VT1-00 titanium (maximum penetration depth of the diamond tip was 40 nm) depending on the dose of irradiation with argon ions were carried out. It was found that the average value of hardness of the surface layers irradiated with argon ions at irradiation doses of 5·1015, 1016, 5·1016 ion/cm2 increased from 8 to 11 times. At an irradiation dose of 1017 ion/cm2, a 12-fold increase in hardness was observed compared to the non-irradiated sample. It was also revealed that at an argon ion dose of 1017 ion/cm2, the reduced modulus of elasticity of multilayer Ni/Al films increased by 3.7 times, and at an irradiation dose of 5·1016 ion/cm2 by 5.4 times compared to the non-irradiated sample. At low values of Wpl/Wtot at an irradiation dose of 1017 ion/cm2, the ratio of the hardness to the reduced modulus of elasticity H/Er of multilayer Ni/Al films increased by a factor of 1.5 compared to irradiation doses of 5·1015, 1016, 5·1016 ion/cm2 and by a factor of 3 compared to the non-irradiated sample. It was found that the resistance to plastic deformation of multilayer Ni/Al films irradiated with argon ions at a dose of 1017 ion/cm2 increased by an order of magnitude or more compared to the sample not subjected to irradiation. Thus, the Ni/Al multilayer films irradiated with argon ions at a dose of 1017 ion/cm2 have high plasticity, reduced modulus of elasticity and high value of hardness at the same time.

The purpose of this work was to investigate the effect of organic surfactants (heptane/toluene) on the morphology of mechanically activated Al (Mg) powder and hydrogen absorption during high-energy ball milling. The samples were obtained by joint mechanical activation (MA) of Al (Mg) powders with organic surfactants. The phase composition, structure and morphology of the powders were investigated by X-ray diffraction and scanning electron microscopy (SEM). The spectra of hydrogen desorption from powders at different MA times were obtained by thermal desorption spectroscopy (TDS) and analyzed. The SEM analysis shows that during MA of aluminum in heptane, particle agglomeration occurs, and during MA of magnesium in heptane, powder dispersion takes place. When the powders are mechanically activated in toluene, a decrease in the particle sizes of both aluminum and magnesium is observed. The degree of hydrogenation of metal powders depends on the features of the decomposition of surfactants during high-energy ball milling. For both Al and Mg, hydrogen absorption is greater at MA in toluene than in heptane. When Al is ground in heptane, the total amount of absorbed hydrogen increases from 2800 to 3600 ppm, and for Mg from 4600 to 6600 ppm. Mechanochemical effects in the toluene environment increase the absorption of hydrogen for Al from 4300 to 10000 ppm and for Mg from 5100 to 8200 ppm. A protective film of hydroxide on the surface of magnesium particles, which is formed at MA, prevents the diffusion of hydrogen.

Published: December 2024

Integrating digital literacy into language teacher preparation programs has gained increasing attention in recent years. With the expanding economic trade with Arab countries, Arabic language education is becoming more important in China. This study aims to identify the needs for developing a digital literacy-integrated speaking syllabus for Arabic pre-service teachers in China. The study presents phase 1: needs analysis of the design and developmental research (DDR) approach. Interviews were conducted to collect data. The finding shows that while digital literacy elements are integrated into the existing speaking syllabus through resources and multimedia presentation teaching approach, it is mainly concentrated on the skill domain rather than the knowledge and attitude domains. The study further found that the challenges for Arabic lecturers to integrate digital literacy are the lack of digital teaching resources, the lack of digital literacy training for lecturers, the heavy teaching tasks but limited class instructional time, and the restrictions of higher education institutional policies. Moreover, Arabic pre-service teachers have basic digital literacy skills for daily use but lack technical knowledge in Arabic and awareness of digital literacy. The results of the study provide valuable insights for curriculum designers and educators for language teacher education programs in China.

Infection control measures are essential to safeguarding healthcare workers (HCWs) and preventing healthcare-associated infections (HAIs) worldwide. This systematic review examines the global implementation of infection control strategies, their effectiveness, and the disparities between high-income countries and low- and middle-income countries (LMICs). A comprehensive search was conducted across multiple databases, focusing on studies published since 2016 that evaluated infection control practices, including hand hygiene, personal protective equipment (PPE), vaccination, environmental cleaning, and waste management. Findings reveal significant variation in compliance and outcomes, with LMICs facing challenges such as resource shortages, inadequate training, and organizational deficiencies. Conversely, high-income countries demonstrate better adherence to infection control protocols, supported by advanced technologies and robust policies. Despite these differences, common barriers such as HCW burnout and vaccine hesitancy persist globally. The review underscores the need for equitable access to resources, international collaboration, and the integration of innovative technologies to enhance infection prevention measures. Addressing these disparities is critical to protecting HCWs, improving patient safety, and achieving global health equity.

Objective: This systematic review aims to identify and analyze the core elements that underpin effective interdisciplinary teamwork in surgical environments and their influence on patient outcomes and procedural efficiency. Methods: We conducted a comprehensive search of electronic databases including PubMed, Scopus, and Web of Science for studies published between January 2000 and December 2024. The review focused on empirical research and reviews that examined teamwork dynamics in surgical settings. Inclusion criteria were studies on interdisciplinary teams involving multiple healthcare specialties in surgical procedures. Data extraction focused on teamwork components, communication patterns, and collaboration outcomes. Results: A total of 45 studies met the inclusion criteria. Analysis revealed that effective teamwork is characterized by clear communication, mutual respect, role clarity, and leadership. These elements were consistently associated with improved patient safety, reduced surgical errors, and enhanced procedural efficiency. The quality of evidence was predominantly high, indicating robust support for the critical role of interdisciplinary teamwork in surgical success. Conclusion: The core elements of interdisciplinary teamwork essential for surgical success include structured communication, well-defined roles, mutual respect among team members, and adaptive leadership. Implementing training programs that focus on these key teamwork components could significantly enhance the quality of surgical care. Future research should explore intervention studies that measure the impact of teamwork enhancement programs on surgical outcomes.
Understanding the Stagnation: Attitude as a Predictor of Extensive Reading Skills without Observable Improvement Despite Metacognitive Integration
Authors: Murtadho Nurul , Ismail Zawawi bin , . Kholisin
Published: December 2024

This study explores the impact of integrating Extensive Reading (ER) enriched with metacognitive strategies on ER skills and positive attitudes towards ER learning. The research employs a one-group pretest-posttest design involving 79 Arabic language students. The measurement of ER skills and positive attitudes towards ER activities was conducted using a questionnaire based on the ten principles of ER. Bayesian paired t-tests did not show a significant improvement in skills or attitudes towards ER activities post-intervention. However, Bayesian linear regression revealed a significant correlation between post-intervention skills and attitudes, with attitudes explaining most of the variation in skills. Although no direct improvement was observed, fostering a positive attitude towards ER may indirectly enhance reading proficiency. These findings underscore the necessity of addressing both cognitive and affective aspects in Arabic language teaching.

Published: December 2024

Residential solid wastes have been becoming an environmental threat for every city, especially crown and high population. The status of Residential Solid Waste (RSW) in a large city, such as Hanoi in general and Dong Anh district in particular, can bring a better vision for management activities. In this study, RSW will be carried out to assess the sources and component contribution being inputs for further forecasting of generated RSW until 2025 in study areas, Dong Anh district, the Tien Duong, and Uy No communes. This study applies the separation of the waste in sites and surveys to calculate the Generated Residential Solid Waste Rate (GRSWR) and in combination with the increased population rate from the famous Euler’s model to predict and forecast the Generated Residential Solid Waste (GRSW) in Dong Anh in the 5 years (2020 - 2025). The results show that the increase in population for every study region will lead to an increase in RSW. In particular, the total GRSW will increase by more than 1,000 tons/year with only 1,000 raised citizens in 5 years. The overall trash collection rate reaches 86.5 % of the total waste generated in the area. The residential waste composition of the Dong Anh district is extremely diverse, with organic matter accounting for nearly 75 %, higher than the average of Hanoi. The important thing is to rigorously and thoroughly implement waste classification at the source according to the regulations of the Law on Environmental Protection (2020) to reduce the amount of waste generated that needs to be collected.

Published: December 2024

Air pollution is becoming a serious global crisis, threatening human health, disrupting the balance of the environment, negatively affecting ecosystems, and contributing to climate change. Accurate long-term air quality prediction plays a key role in building early warning systems to mitigate these negative impacts. Efforts to forecast air quality through the combination of knowledge from environmental science, statistics, and computer science have attracted much attention. Among them, deep learning and advanced machine learning have demonstrated an outstanding ability to detect complex non-linear patterns from environmental data. However, the application of deep learning to air quality prediction is still quite new. This paper proposes a deep-learning model using the LSTM (Long Short-Term Memory) network to predict air quality in Hanoi. The research results demonstrate that the proposed model is capable of predicting the air quality index with high accuracy, close to actual values ​​from monitoring data.

Published: December 2024

For mathematical models in general and hydrological models in particular, the accuracy of input data and the detail in using that data greatly affect the calculation results. For each specific requirement, how detailed the input data needed to ensure the accuracy while still meeting the requirements of real-time tasks is an issue that needs to be surveyed and researched. In this paper, the authors use HEC-HMS model with two types of LULC (Land use-Land cover) maps and different ratios of basin division to calculate Tuyen Quang reservoir inflow for August 2023 and July 2024 floods. The results show that the Jaxa LULC map gives better results than the Microsoft and Esri LULC map and divides Tuyen Quang basin into 29 sub-basins is more suitable than 09 and 49 sub-basins. From there, the influence of LULC map as well as the ratio of basin division on the accuracy and calculation time are commented.
