This paper proposes a discrete-time Model Reference Adaptive Controller (MRAC), applied to a Half-Bridge synchronous buck converter for charging batteries. The system uses an LCL filter that interfaces the power converter and the batteries. A virtual plant method is proposed for better transitory response of the adaptive control system. The model reference utilizes a reduced order, to simplify the project of the adaptive controller. Simulation results are presented for validation of the control project. © 2024 IEEE.

Journal of Quality 2024年第6期31卷 388-415页

The physical and mental health issues of employees have received attention from all walks of life, especially front-line employees who are most likely to be ignored and lead to resignation. This study introduces the cognitive-affective processing system (CAPS) to explain the different degrees of work-life balance that occur due to the impact of individual differences when employees face abusive supervision. This study explored psychological ownership, attribution motivation for abusive supervision, and emotional intelligence, among other psychological variables, through a questionnaire survey of 582 health care providers (HCPs) including clinics, hospitals, long-term care institutions, other medical systems, etc. The research results show that abusive supervision can affect work-life balance through psychological ownership. Furthermore, psychological ownership can completely mediate the relationship between abusive supervision and work life enhancement, and when employees perceive abusive supervision, attributing it to performance promotion motives can effectively reduce the negative impact of abusive supervision on psychological ownership. © 2024, Chinese Society for Quality.

The current era of urbanization, globalization, and climate change is a challenge in urban planning and development in the future. There is still a lack of literature that offers various conceptual frameworks for stakeholders and city governance actors in dealing with urban threats. Therefore, this study aims to fill this research gap to encourage resilient and sustainable governance to face future challenges and threats. This research provides scientific guidelines and recommendations for developing governance studies to realize urban resilience. The method of this study is a systematic literature review and meta-analysis through the PRISMA protocol using literature from 2005 to 2023. The findings of this study indicate that governance approaches must pay attention to various dimensions of resilience such as: (1) social, ecological, economic, institutional, and infrastructure. This study argues that government resilience needs to be built based on key elements of sustainability such as: (1) economic prosperity;(2) Social justice;and (3) Environmental sustainability. This study identifies key characteristics of resilience governance as Reflective, Robust, Integrated, Resourceful, Flexible, Redundant, and Inclusive. This urban resilience governance design can help encourage urban resilience and sustainability by increasing the agility of urban ecosystems, preventing future disturbances and threats, reversing crises, and creating sustainability based on prosperity, justice, and sustainability. These findings will be useful in understanding the dynamics of urban vulnerability and resilience as well as measuring and managing strategies based on the indicators developed. © The Author(s) 2025.

This study presents the design and implementation of a sensor-based system for detecting rodent activity. The proposed system utilizes infrared (IR) receivers for detecting rodent presence and can incorporate IP cameras to capture intruder images. Data collected by sensor nodes are transmitted to a database via Wi-Fi for web access. The system employs a reflective-type IR sensor comprising an emitter and a receiver aligned in the same direction to discern approaching or receding objects. Power-efficient operation is ensured through the use of the Heltec Wireless Stick Lite MCU and LoRa transceivers for data transmission. Results demonstrate the system's effectiveness in monitoring rodent behavior, with power consumption averaging 67.4mA to 69.5mA, supported by two 18650 batteries for up to 4 days of continuous operation. During the 18-day experiment duration, a total of 1,453 instances were recorded. © 2024 IEEE.

It is important to figure out the patterns of woven fabrics before producing woven fabric with a machine. Recognition of woven fabric pattern usually with the help of the human eye can understand the fabric pattern. However, this manual checking takes a lot of time, money, and work, which will raise the cost of making woven fabrics. This study uses the VGG16, VGG19, MobileNet, and Inception-V3 methods to classify woven fabric patterns. It also wants to see how fine-tuning method can help algorithms be more accurate at classifying images. The research was divided into four phases, including image acquisition, image preprocessing, image classification and evaluation. A total of 978 pictures of motifs included in the research dataset. There are 351 images for the cotton class, 76 images for linen, 195 images for silk, and 356 images for wool. As the result, the highest testing accuracy was in the Inception-V3 experiment (with fine-tuning) of 72.51%, and the lowest was in the VGG19 experiment (with fine-tuning) of 52.92%. © 2022 ICIC International.

Rip currents have long posed a serious threat to beachgoers and swimmers. Despite numerous preventive measures throughout the period, the fatality rate [1] underscores the need for a robust rip current detection system. Recently deep learning models have shown promising results in rip current detection, outperforming traditional methods. However, these models still exhibit some accuracy limitations due to insufficient data distribution. To address this challenge, we incorporate a novel largest dataset [2] comprising over 110,215 Korean coastline images. Through the comparative study of the state-of-the-art models, we aim to analyze the detection accuracy of each model and gain a deeper understanding of their intensity over rip current detection. In comparison to the other rip current datasets, the evaluation results on our proposed dataset demonstrate a remarkable elevation in accuracy, reaching 79.4 mAP. Further, we employ the EigenCAM (Eigen Class Activation Maps) to interpret the intense regions of the rip currents and to gain a deeper comprehension of rip current explainability. This comprehensive analysis marks a significant step toward improving rip current safety and understanding. © 2024 Global IT research Institute - GIRI.
