To address these challenges, this paper proposes an improved detection algorithm based on YOLOv11n. First, a Dynamic Multi-Scale Feature Fusion and Adaptive Weighting approach is employed to design an Adaptive Focused Diffusion Pyramid Network (AFDPN), which enhances the feature expression and transmission capability of shallow small targets, thereby reducing the loss of detailed information. Then, combined with an Edge Enhancement (EE) module, the model improves the extraction of infrared small target edge features through low-frequency suppression and high-frequency enhancement strategies. Experimental results on the publicly available HIT-UAV dataset show that the improved model achieves a 3.8% increase in average detection accuracy and a 3.0% improvement in recall rate compared to YOLOv11n, with a computational cost of only 9.1 GFLOPS. In comparison experiments, the detection accuracy and model size balance achieved the optimal solution, meeting the lightweight deployment requirements for drone-based systems. This method provides a high-precision, lightweight solution for small target detection in drone-based infrared imagery.</p> Jiale Wang Copyright (c) 2025 Author(s) 2025-10-31 2025-10-31 9 6 1 6 10.26689/jera.v9i6.11676 AW-HRNet: A Lightweight High-Resolution Crack Segmentation Network Integrating Spatial Robustness and Frequency-Domain Enhancement https://ojs.bbwpublisher.com/index.php/JERA/article/view/12055 <p>The study presents AW-HRNet, a lightweight high-resolution crack segmentation network that couples Adaptive residual enhancement (AREM) in the spatial domain with Wavelet-based decomposition–reconstruction (WDRM) in the frequency domain. AREM introduces a learnable channel-wise scaling after standard 3 × 3 convolution and merges it through a residual path to stabilize crack-sensitive responses while suppressing noise. WDRM performs DWT to decouple LL/LH/HL/HH sub-bands, conducts lightweight cross-band fusion, and applies IDWT to restore detail-enhanced features, unifying global topology and boundary sharpness without deformable offsets. Integrated into a high-resolution backbone with auxiliary deep supervision, AW-HRNet attains 79.07% mIoU on CrackSeg9k with only 1.24M parameters and 0.73 GFLOPs, offering an excellent accuracy–efficiency trade-off and strong robustness for real-world deployment.</p> Dewang Ma Tong Lu Copyright (c) 2025 Author(s) 2025-11-03 2025-11-03 9 6 7 17 10.26689/jera.v9i5.12055 Technological Innovation and Clinical Application Prospects of Vascular Interventional Surgical Robots https://ojs.bbwpublisher.com/index.php/JERA/article/view/12831 <p style="font-weight: 400;"><em>As a cutting-edge technology in the field of medical robotics, vascular interventional surgical robots have made remarkable progress in recent years.

To address this limitation, this paper proposes a reverse-modeling approach that reconstructs parametric CAD models from multi-view RGB-D point clouds. Multi-frame point-cloud registration and fusion are first employed to obtain a complete 3-D point cloud of the target object. A region-growing algorithm that jointly exploits color and geometric information segments the cloud, while RANSAC robustly detects and fits basic geometric primitives. These primitives serve as nodes in a graph whose edge features are inferred by a graph neural network to capture spatial constraints. From the detected primitives and their constraints, a high-accuracy, fully editable parametric CAD model is finally exported. Experiments show an average parameter error of 0.3 mm for key dimensions and an overall geometric reconstruction accuracy of 0.35 mm.

Policies such as the <em>Notice on the Construction of China Cultural Heritage-Themed Tourism Routes</em> and the <em>Dongpo Journey-China Cultural Heritage-Themed Tourism Route Master Plan</em> have been successively issued, encouraging the creation of cultural-tourism integration projects that primarily feature immovable cultural relics and combine specific themes. However, current digital tours at cultural heritage sites often suffer from fragmented cultural knowledge transmission, a lack of personalized user experience, and insufficient contextual learning effects. To address these issues, this study takes the “Dongpo Travel” digital tour mini-program as a case study to explore the design of a thematic tourism route digital tour platform that integrates ontology and user profiling. The platform achieves structured transmission of Dongpo cultural knowledge by constructing historical relic tour maps, improving cultural tourism route services, setting up post-tour incentive mechanisms, and developing contextual learning modules. This meets the personalized travel needs of different users and helps tourists deepen their cultural learning during visits. Practice shows that the platform can operate stably at the Su Causeway in the West Lake Scenic Area, covering approximately 27 Dongpo cultural sites and serving over 500 people daily. It not only promotes the revitalization and inheritance of Dongpo cultural heritage but also provides a replicable solution for the digital transformation of the cultural tourism industry. Additionally, it effectively enhances the efficiency of contextual learning at cultural heritage sites and offers a reference for the construction of similar thematic tourism route digital tour platforms.</p> Yueying Huang Li Shen Jinxin Wang Zhigang Ding Copyright (c) 2025 Author(s) 2025-12-16 2025-12-16 9 6 328 336 10.26689/jera.v9i6.13187 Design of an Abnormal Behavior Monitoring System for Elderly Living Alone Indoors https://ojs.bbwpublisher.com/index.php/JERA/article/view/13188 <p>Aiming at the prominent indoor safety hazards and the difficulty in timely detecting abnormal behaviors of elderly living alone against the backdrop of accelerating population aging, an abnormal behavior monitoring system for elderly living alone indoors, integrating multi-sensor technology and intelligent algorithms, is designed.

Traditional manual inspection is slow, costly, and prone to error, motivating the use of unmanned aerial vehicles (UAVs) with infrared and visible cameras for automated monitoring. In this paper, we propose a YOLO-based multi-task framework for simultaneous PV defect detection and hazard-level classification. We constructed a dataset of 5,000 annotated UAV images from the Riyue PV power plant, covering ten defect categories and four severity levels (LV1–LV4). To support severity grading, the YOLO architecture was extended with a dual-task head and an ordinal regression scheme. The model was trained with a compound loss combining bounding-box regression, objectness, defect classification, and hazard-level supervision. Experimental evaluation on real UAV inspection data (224 strings, 30 ground-truth defects) shows that the proposed approach achieves mAP50 of 95.6%, recall of 92.7%, and severity classification accuracy of 90.8%. The system detects both minor anomalies (e.g., bird droppings, soiling) and critical faults (e.g., missing panels, disconnections) in real time at over 40 FPS, providing actionable insights for maintenance prioritization. These results demonstrate that YOLO-based UAV inspection offers a robust and scalable solution for intelligent PV O&amp;M.</p> Qing Yi Jiayou Sun Shanying Su Houzhi Wei Ke Wang Zhihui Qi Siyu Teng Copyright (c) 2025 Author(s) 2025-12-16 2025-12-16 9 6 343 351 10.26689/jera.v9i6.13189 Design and Implementation of a Family Private Medical Health Intelligent Management System https://ojs.bbwpublisher.com/index.php/JERA/article/view/13190 <p>With technological advancements, traditional medical models have been unable to meet people’s demands for personalized and convenient medical services.

Different control systems have different brands and cannot communicate directly via networks. Moreover, due to network security concerns, the main control of unit units and the auxiliary control system of the entire plant cannot communicate directly via networks either. The commonly adopted methods for signal exchange between control systems are hardwiring and 485 communications. Both have obvious drawbacks, where hardwiring requires a large number of channels and cable laying; 485 configuration is difficult, not easy to maintain, and faults are hard to locate. This paper studies how to strike a balance between the two, using a minimal amount of hardwiring to transmit a large number of signals, which is safe, reliable, cost-effective, and can be maintained by any control personnel without network security risks.</p> Yonggang Deng Copyright (c) 2025 Author(s) 2025-12-16 2025-12-16 9 6 362 369 10.26689/jera.v9i6.13191 Visualization Analysis of Research Status and Hotspots of Computerized Respiratory Sound Analysis Based on CiteSpace https://ojs.bbwpublisher.com/index.php/JERA/article/view/13192 <p><strong>Objective:</strong> To explore the research landscape and hotspots of Computerized Respiratory Sound Analysis (CORSA) and provide a reference for future in-depth studies.<strong> Methods:</strong> Literature related to CORSA published up to August 27, 2020, was retrieved from the Web of Science Core Collection.

Current hotspots include respiratory sound acquisition and processing, feature extraction methods such as Mel-frequency cepstral coefficients (MFCCs), and classification techniques based on machine learning and deep learning. CORSA is suitable for diverse populations and is widely applied in respiratory diseases, especially bronchial asthma. Its non-invasive nature offers particular advantages for infants and pregnant women. Although CORSA demonstrates strong clinical potential, its clinical translation remains limited. Advancing clinical applications and bridging the gap between research and practice will be key directions for future development. The prominence of top-tier respiratory and engineering journals among citations suggests that CORSA is an emerging and influential research frontier.</p> Yan Wang Yu Xu Yali Fan Yang Zhang Zixuan Qi Yang Cheng Copyright (c) 2025 Author(s) 2025-12-16 2025-12-16 9 6 370 384 10.26689/jera.v9i6.13192 Engineering Risk Prevention and Control Strategies from the Perspective of Technical Management in the Field of Electromechanical Engineering https://ojs.bbwpublisher.com/index.php/JERA/article/view/13193 <p>This study explores engineering risk prevention and control in electromechanical engineering from the technical management perspective.

To this end, this paper proposes an ultrasonic temperature measurement method that combines YOLOv11 target detection with energy-type weighted cross-correlation algorithm. The YOLOv11 model is utilized to conduct target detection and key area positioning on the ultrasonic signal waveform diagram, automatically identifying characteristic waveforms such as node waves and end face waves, and achieving adaptive extraction of the effective signal interval. Further introduce the energy-based weighted cross-correlation algorithm. Based on the signal energy distribution, the cross-correlation results are weighted and processed to enhance the main wave response and suppress noise interference. Experiments show that the YOLOv11 model has high detection accuracy (Precision = 0.987, Recall = 0.958, mAP@50 = 0.988); The proposed method maintains the stability of time delay estimation under strong noise and high temperature (&gt; 1200℃), with the average time delay error reduced by approximately 35% to 50% compared to traditional algorithms. This verifies its high robustness and temperature measurement accuracy in complex environments, and it has a promising engineering application prospect.</p> Qianxiang Zhang Yanlong Wei Guanglei Qiang Gang Yang Copyright (c) 2025 Author(s) 2025-12-16 2025-12-16 9 6 403 412 10.26689/jera.v9i6.12644 An Improved PBFT Algorithm Based on Dual Scoring Mechanism https://ojs.bbwpublisher.com/index.php/JERA/article/view/12584 <p>The traditional Practical Byzantine Fault Tolerance (PBFT) approach suffers from three critical deficiencies: arbitrary primary node election, excessive network transmission overhead, coupled with the absence of node incentive mechanisms. To address these issues, this study proposes a refined PBFT strategy utilizing dual scoring (Double Scoring Practical Byzantine Fault Tolerance, DS-PBFT). The algorithm innovatively combines hardware performance evaluation with a dual-dimensional node scoring system. The algorithm first employs bucket sorting technology to quantitatively evaluate node hardware resources, followed by constructing a comprehensive scoring model through credit values and recommendation values. According to the scoring outcomes, the framework hierarchically divides nodes into primary node, follower node and backup nodes groups in a 1:4:5 ratio, substantially decreasing the quantity of nodes involved in consensus. Additionally, this approach streamlines the Commit-Reply stages within the consistency protocol, substantially reducing communication overhead. Experimental validation demonstrates that DS-PBFT maintains security while achieving notable improvements in consensus efficiency, significant reductions in communication costs, and enhanced defense capabilities against malicious nodes.</p> Peng Zhao Weixuan Xu Copyright (c) 2025 Author(s) 2025-12-16 2025-12-16 9 6 413 426 10.26689/jera.v9i6.12584 Thematic Tour Interactive Experience Platform Empowered by Dynamic Path Planning and Augmented Reality: An Empirical Study on Enhancing Visitor Engagement and Cultural Identity https://ojs.bbwpublisher.com/index.php/JERA/article/view/13195 <p>This study focuses on the application of dynamic route planning and augmented reality (AR) technology within interactive theme trail platforms.

To address existing security challenges in healthcare data sharing, we propose a collaborative data cooperation model based on blockchain and federated learning, Through federated learning technology, data is made “usable but not visible” by enabling medical institutions to share only encrypted model parameters, thereby preventing the leakage of raw data. Meanwhile, blockchain technology is introduced to establish a decentralized trust mechanism, utilizing smart contracts to automate data access management and track training processes. In addition, the dual security protection strategy is designed, where differential privacy and Paillier homomorphic encryption technology are adopted to resist member reasoning attacks and ensure secure storage and sharing of information. Through security analysis and experimental validation, the scheme has been proven to have good security and usability.</p> Jia Sun Peng Zhao Copyright (c) 2025 Author(s) 2025-12-16 2025-12-16 9 6 443 451 10.26689/jera.v9i6.12502 Research on Human-Robot Interaction Technology Based on Gesture Recognition https://ojs.bbwpublisher.com/index.php/JERA/article/view/13197 <p>With the growing application of intelligent robots in service, manufacturing, and medical fields, efficient and natural interaction between humans and robots has become key to improving collaboration efficiency and user experience. Gesture recognition, as an intuitive and contactless interaction method, can overcome the limitations of traditional interfaces and enable real-time control and feedback of robot movements and behaviors. This study first reviews mainstream gesture recognition algorithms and their application on different sensing platforms (RGB cameras, depth cameras, and inertial measurement units). It then proposes a gesture recognition method based on multimodal feature fusion and a lightweight deep neural network that balances recognition accuracy with computational efficiency. At system level, a modular human-robot interaction architecture is constructed, comprising perception, decision, and execution layers, and gesture commands are transmitted and mapped to robot actions in real time via the ROS communication protocol. Through multiple comparative experiments on public gesture datasets and a self-collected dataset, the proposed method’s superiority is validated in terms of accuracy, response latency, and system robustness, while user-experience tests assess the interface’s usability. The results provide a reliable technical foundation for robot collaboration and service in complex scenarios, offering broad prospects for practical application and deployment.</p> Ming Hu Copyright (c) 2025 Author(s) 2025-12-16 2025-12-16 9 6 452 461 10.26689/jera.v9i6.13197
