Studying the Impact of TensorFlow and PyTorch Bindings on Machine Learning Software Quality
Authors: Li Hao , Rajbahadur Gopi Krishnan , Bezemer Cor-Paul
Published: July 2024

Bindings for machine learning frameworks (such as TensorFlow and PyTorch) allow developers to integrate a framework’s functionality using a programming language different from the framework’s default language (usually Python). In this article, we study the impact of using TensorFlow and PyTorch bindings in C#, Rust, Python and JavaScript on the software quality in terms of correctness (training and test accuracy) and time cost (training and inference time) when training and performing inference on five widely used deep learning models. Our experiments show that a model can be trained in one binding and used for inference in another binding for the same framework without losing accuracy. Our study is the first to show that using a non-default binding can help improve machine learning software quality from the time cost perspective compared to the default Python binding while still achieving the same level of correctness.
Evolutionary Game Analysis of UGC Copyright Infringement Governance
Authors: Yang Sen
Published: July 2024

This paper presents an evolutionary game model of the “government‐platform‐platform user” based on the assumption of bounded rationality. The model explores the copyright governance mechanism of user‐generated content (UGC) in China by analyzing the strategic interaction between managers and the managed and the influence of various factors. The findings highlight that the government plays a leading role in the governance mechanism of UGC copyright, and the participation of the platform, as the direct manager of information content, can greatly improve the efficiency of supervision. Increasing government penalties, reducing excess revenue from passive platform filtering, and imposing additional payments for users’ infringing use can expedite the adoption of evolutionary stability strategies. Furthermore, there exists a practical threshold for government incentives for platforms. Therefore, the construction and optimization of the UGC copyright governance mechanism need to be supported by a dynamic and coordinated reward and punishment system, diversified business objectives, and continuously improving users’ copyright awareness.

Published: July 2024

This review is aimed at unraveling the intricacies of diabetic self‐management among geriatric people, drawing on current insights and understanding the complex paths geriatric people navigate. A wide search was conducted in health‐oriented databases, including CINAHL, Embase, PsycINFO, MEDLINE, PubMed, Web of Science, and Cochrane Library, while gray literature was excluded. The search combined keywords and subject headings, focusing on the geriatric population, diabetes, self‐management, and qualitative research. A three‐tiered screening process was employed, with titles and then abstracts initially reviewed. Full‐text analysis followed, with disagreements resolved among reviewers. In total, there were 248 participants included across these eight studies. Positive attitudes and perceptions were found to play a significant role in optimizing diabetes self‐care outcomes. Support from family and friends was identified as crucial for self‐care, while healthcare professionals often lacked adequate support and encouragement. Participants emphasized the importance of listening to their bodies and acknowledging hidden issues. These themes collectively highlight the multifaceted aspects of diabetes self‐care and the impact of various factors on the self‐management experiences of geriatric individuals with diabetes. The goal of this review is not to objectify self‐management as a treatment strategy but to emphasize the importance of cultivating positive attitudes, respecting individual values, and addressing cultural and ethnic differences in healthcare practices to enhance self‐management in this population. By embracing cultural diversity, understanding barriers, and respecting individual values, healthcare professionals and policymakers can improve the quality of life for the geriatric population living with diabetes.
Optimization Design and Propulsion System Sizing Methodology of Double‐Layer Staggered Octocopter
Authors: Zhu He , Wei Yuanzun , Nie Hong , Wei Xiaohui , Deng Siqiang
Published: July 2024

Small‐scale multirotor drones often require careful consideration of many aspects including the selection of structural parameters and the propulsion system. Double‐layer staggered octocopters (DLSOs) are a type of arrangement with advantages in structural layout and aerodynamic performance compared with other configurations, which can conserve structural space and restrict the aerodynamic interaction between the rotors. For the purpose of increasing thrust, reducing weight, and maximizing power efficiency, DLSOs are designed with the optimal combination of structural parameters and propulsion systems using noncustomized products. The optimization process is divided into two steps. First, utilizing the simulation results from Latin hypercube design‐guided sample points, a surrogate model is established by the radial basis function (RBF)–based neural network to forecast the thrust of the staggered rotors. An optimal structural configuration of the DLSO is then obtained by applying the adaptive geometry estimation–based multiobjective evolutionary algorithm (AGE‐MOEA). Second, based on an improved propulsion system sizing method, the propulsion system, including motors, electronic speed controllers (ESCs), and batteries, is further optimized using standard methods and noncustomized propulsion system product data, to minimize weight and maximize power efficiency. The optimized DLSO has greatly enhanced its total thrust and power efficiency when compared to some well‐known market products.

Published: July 2024

This research aims to examine the influence of learning motivation based on environmental conditions, desire to work, and main desires. To achieve this, a quantitative research design was used, and a total of 500 students (101 boys and 399 girls) in Indonesia were selected as respondents using proportional random sampling techniques. Data collection was carried out using a learning motivation scale questionnaire. The results showed that students had a high level of motivation, with an average score of 50.8. The desire to work can be seen from hopes and dreams, as well as a conducive environment. It is known that external factors such as encouragement from others and involvement in activities have a greater influence with significance scores of 0.801 and 0.766 respectively. Meanwhile, appreciation and hopes or aspirations each received a score of 0.709 and 0.704. This implies that encouragement and activity can be integrated into the student's self. The research also shows that gender does not have a significant effect on the desire to learn. However, providing appropriate encouragement and rewards will increase students' willingness to learn, which can be maintained by educational institutions and parents and instill a desire for personal progress and development.

Authors: Jothi Thangavel , Arun Manoharan , Varadarajan Murugesan
Published: July 2024

Hybrid smart grids which depend on renewable energy have substantial challenges to their reliability and efficiency due to power quality issues. However, the performance and dependability of the system might be impacted by power quality concerns caused by the intermittent nature of renewable energy sources and the presence of nonlinear and unbalanced loads. This study suggests that a hybrid renewable energy-based smart grid can improve power quality by using a dynamic voltage restorer (DVR), a flexible alternating current transmission system device. The goal is to improve voltage stability, reduce voltage spikes and harmonic distortion, and provide a clean power supply. This study's primary contributions are the design and execution of the cascaded H-bridge DVR topology, the development of a modified synchronous reference frame-based controller and a thorough examination of the performance of the integrated DVR system. Total harmonic distortion and voltage regulation are two power quality metrics used to evaluate the effectiveness of the suggested technique in MATLAB simulations.

Authors: Pratomo Leonardus Heru , Paudel Sushil , Cahyadi Bagus Kusuma
Published: July 2024

Over the past decade, much research and development has gone into the use of electric power converters, and the trend is upward. Inverters are employed when converting DC voltage to AC voltage. Typically, inverters perform functions such as voltage boost (to compensate for voltage decrease) or both voltage buck and boost. Other issues to consider include the structure of the inverter topology and the control method. Based on the problem, a study was conducted on a buck-boost inverter that integrates an H-bridge inverter and a single ended primary inductor converter (SEPIC). The H-bridge inverter is widely recognized for its simplicity of operation and always runs in buck mode. The SEPIC converter always runs in buck-boost mode. Since it is unipolar, it can operate as a buck or boost when combined with SEPIC AC-AC. The output voltage is significantly improved because it has several filters to enhance the signal. This hybrid topology is controlled by sinusoidal pulse width modulation, resulting in a straightforward control technique with outstanding performance. The H-bridge inverter operates in index modulation 0-100%, and the SEPIC converter more than 50%. In the lab, a computational and implementation procedure is used to test the effectiveness of the hybrid topology and control method under consideration. The test results show that the hybrid architecture can function within the desired parameters. The proposed inverter has 4.531% THD_V, 4.531% THD_I, and 97.85% efficiency under simulation.

Published: July 2024

Nowadays, technology has become an indispensable instructional tool. Technology-integrated teaching approach has been recognized in research studies as an effective means to address the declination of the English language’s linguistic competence of the learners. This research determined the effectiveness of a flipped classroom, a technology-integrated teaching approach, to a specific group of Filipino language learners. Utilizing a
quasi-experimental research design, 102 English pre-service teachers enrolled in a state university were selected purposively to be the participants of the study and were categorized into two groups, the very good, and the good groups. The expert-validated pre-post-test questionnaire, course syllabus, and lesson exemplars were used to gather the data on learners’ linguistic competence. Results of the paired t-test revealed a significant mean gain of the students’ scores both from very good and good groups pre-post the employment of the flipped classroom approach. The flipped classroom approach is one of the technology-integrated approaches to be used to augment the learners’ linguistic competence regardless of students’ group categories. It is recommended that the flipped classroom approach be used by teachers handling different disciplines delivered in English to mitigate the students’ dilemma on English language proficiency.

This study aims to study the factors contributing to sexual abuse of children in Malaysia. This study uses the nominal group technique (NGT) approach in determining the list of factors for victims and predators, involving six experts from six different institutions that are directly involved with the issue of child sexual abuse (CSA). The findings of the study show that there are four factors that reach the highest value (86.7%) for the victims, which are naivety and lack of knowledge, family problems, unsafe environment, and social media. As for predator factors, two factors were rejected because they reached a low value, namely the factor of “wanting to try” (60%), and mental health issues (66.67%). Finally, the highest predator factors found are family crisis and upbringing style, with each reaching a value of 83.33%. The findings of the study show that several factors in the occurrence of sexual abuse against children can be identified. This matter needs attention so that this problem can be controlled and prevented from spreading in the community. The NGT method shows an effective and acceptable methodology for solving the problems of this study.

Following the mandatory adoption of project-based learning (PjBL) in Indonesian vocational education, there has been a revival in popularity as a prevalent instructional approach in higher education. However, no research on students' attitudes toward mandatory PjBL in Indonesia has raised concerns about its acceptance. This article describes Indonesian vocational college students’ attitudes toward PjBL in English language courses. The study specifically focuses on cognitive, affective, and behavioral attitudes and how students perceive the advantages of PjBL for their English skills and career aspirations. This quantitative study included 336 Indonesian vocational students from twelve state and private colleges in Indonesia. The results of this study revealed that students had a positive attitude toward PjBL in their English courses. Students’ cognitive, affective, and behavioral attitudes indirectly influenced their career aspirations, with English skill benefits acting as mediators. This study proves that how students feel, think, and behave affects their future career goals by shaping how they perceive improvement in their English language skills.

Published: July 2024

This study, utilizing the expectancy-value theory, examines the relationship between career development, learning motivation, and employment capabilities among Chinese architecture undergraduates. Surveying 319 students from five Chinese universities, the research reveals that career development has a positive impact on both employment capabilities and learning motivation. Learning motivation, in turn, positively affects employment capabilities and acts as a mediator between career development and employment capabilities. These findings underscore the significance of proactive career planning, goal setting, and intrinsic learning motivation in enhancing students' employment capabilities. For practical applications, educational institutions can design comprehensive career development programs to assist students in defining career goals and igniting intrinsic motivation for learning, thereby fostering career success and employability among architecture students.

Published: July 2024

As the English language is required to be used beyond English subject classrooms in English as a foreign language (EFL) country, teachers from various disciplines, such as math and science, may find it challenging when having to conduct the course in English. Therefore, this professional development project aimed to address the issue of math and science
pre-service teachers lacking classroom language knowledge when teaching in an EFL setting. The project involved a month-long training program for pre-service teachers on how to use English classroom language in teaching Math and Science to elementary and high school students. Pre- and
post-training video recordings were collected to evaluate the linguistic development of the participants in classroom language use. Additionally, journal entries were collected to know the participants' insights on pedagogical growth and perceptions when using English in teaching content lessons. The findings indicated a significant improvement in the participants' classroom language use in various areas such as greetings and lesson introductions, feedback and instructions, classroom management, requests and questions, and lesson conclusions. The pre-service teachers also reflected on their pedagogical development in their journals. The article discusses some implications of the project that could benefit similar initiatives in EFL settings that use English as partial or full medium of instruction.
