https://ojs.bbwpublisher.com/index.php/JERA/article/view/11317
<p>In heavy-duty long-distance transmission scenarios, steel wire ropes are widely used due to their unique advantages, and their safety is very important, which has also led to the rapid development of non-destructive testing technology for steel wire ropes. The non-destructive testing technology for steel wire ropes is influenced by various factors such as its own structure and external working environment, and the testing process is relatively complex. Multiple testing methods and related types of sensors have also emerged. The electromagnetic detection method is currently the most effective method, but it also has its limitations in development and has not yet fully achieved the expected detection goals. In order to completely replace manual inspection work with the development of non-destructive testing technology for steel wire ropes, more in-depth research and long-term accumulation are still needed.</p>Yang GaoJun YangBaohua QiaoChen QianQifu Zhang

2025-08-072025-08-0794242910.26689/jera.v9i4.11434Detecting Drowsiness Behind the Wheel: A Lightweight Approach Based on Eye and Mouth Aspect Ratios
https://ojs.bbwpublisher.com/index.php/JERA/article/view/11435
<p>Driver distraction is a leading cause of traffic accidents, with fatigue being a significant contributor. This paper introduces a novel method for detecting driver distraction by analyzing facial features using machine deep learning and 68 face model. The proposed system assesses driver tiredness by measuring the distance between key facial landmarks, such as the distance between the eyes and the angle of the mouth, to evaluate signs of drowsiness or disengagement. Real-time video feed analysis allows for continuous monitoring of the driver’s face, enabling the system to detect behavioral cues associated with distraction, such as eye closures or changes in facial expressions. The effectiveness of this method is demonstrated through a series of experiments on a dataset of driver videos, which proves that the approach can accurately assess tiredness and distraction levels under various driving conditions. By focusing on facial landmarks, the system is computationally efficient and capable of operating in real-time, making it a practical solution for in-vehicle safety systems. This paper discusses the system’s performance, limitations, and potential for future enhancements, including integration with other in-vehicle technologies to provide comprehensive driver monitoring.</p>Heyang Ni

2025-08-082025-08-0894394710.26689/jera.v9i4.11436Analysis and Research on Monitoring Devices for Deformation of Wind Turbine Pitch Bearing
https://ojs.bbwpublisher.com/index.php/JERA/article/view/11437
<p>The pitch bearing is a component in wind turbine units used to adjust the angle of the fan blades to adapt to the wind direction, so as to maximize the utilization of wind energy. Due to the different working mode of the pitch bearing itself compared with ordinary small bearings and the harsh working environment, the pitch bearing is prone to faults such as cracking and deformation. In severe cases, it will lead to overall damage to the pitch bearing, causing the blade to fall from a high altitude and even injuring personnel. Therefore, this paper conducts a patent analysis and technical decomposition of the deformation monitoring device for pitch bearings, analyzes and summarizes the development process of existing deformation monitoring devices for pitch bearings. Combined with the TRIZ evolution theory and based on the S-curve, it is concluded that the current deformation monitoring device for pitch bearings is in the transitional stage between the infant period and the growth period, and discusses the possible subsequent evolution directions. Through reviewing relevant literature, it is found that inner ring cracks first appear near the upper and lower surfaces of the bolt holes in the inner ring of the pitch bearing. To this end, a new type of deformation monitoring device for pitch bearings is designed. The fiber optic displacement sensor is used for qualitative monitoring of initial cracks near the surface of the bolt holes in the inner ring of the pitch bearing. After cracks are detected, the eddy current sensor is used for quantitative monitoring of whether there are extended cracks between the cracked bolt holes and adjacent bolt holes. Finally, the work done in this paper is summarized and prospected.</p>Xiangyue Xu

https://ojs.bbwpublisher.com/index.php/JERA/article/view/11439
<p>Abnormal driving behavior includes driving distraction, fatigue, road anger, phone use, and an exceptionally happy mood. Detecting abnormal driving behavior in advance can avoid traffic accidents and reduce the risk of traffic conflicts. Traditional methods of detecting abnormal driving behavior include using wearable devices to monitor blood pressure, pulse, heart rate, blood oxygen, and other vital signs, and using eye trackers to monitor eye activity (such as eye closure, blinking frequency, etc.) to estimate whether the driver is excited, anxious, or distracted. Traditional monitoring methods can detect abnormal driving behavior to a certain extent, but they will affect the driver’s normal driving state, thereby introducing additional driving risks. This research uses the combined method of support vector machine and dlib algorithm to extract 68 facial feature points from the human face, and uses an SVM model as a strong classifier to classify different abnormal driving statuses. The combined method reaches high accuracy in detecting road anger and fatigue status and can be used in an intelligent vehicle cabin to improve the driving safety level.</p>Zekai Yan

https://ojs.bbwpublisher.com/index.php/JERA/article/view/11446
<p>Wireless energy transmission technology through the transmitter will be converted into microwave, laser or electromagnetic field and other energy carriers to realize the transmission of space, and the receiver will be captured back to the energy conversion of electrical energy, the whole process can be completed without physical contact energy transfer. The core mechanism is to build the energy coupling channel of the transmitter-receiver system, and realize the spatial power transmission through electromagnetic field interaction. In the electromagnetic induction coupled transmission system, the industrial frequency alternating current is converted into direct current by rectification and filtering, and then converted into high-frequency alternating current by high-frequency inverter. This current excites the primary side transmitting winding to generate a time-varying magnetic field, and through magnetic coupling in the secondary side receiving winding inductance electromotive force, and ultimately through the high-frequency rectifier and power regulation circuit to the load power supply. The essence of the process is to establish a transceiver double-ended resonant network, through the magnetic field resonance to achieve efficient energy exchange, and its transmission characteristics follow the laws of electromagnetic induction and the circuit resonance principle of double constraints.</p>Yuxi Wu

2025-08-082025-08-089411712410.26689/jera.v9i4.11448Analysis of Guqin Playing Techniques Based on Artificial Intelligence
https://ojs.bbwpublisher.com/index.php/JERA/article/view/11449
<p>The Guqin art form is one of China’s oldest musical traditions and is recognized as a significant part of the world’s intangible cultural heritage. Numerous ancient scores have survived to the present day, but only a select few have been adapted for contemporary music. While ancient Guqin scores can be translated into modern numbered or staff notation, their rhythmic elements cannot be accurately replicated. The process of converting these scores into a simplified Guqin notation presents challenges, particularly in selecting appropriate fingerings. To address the issues related to playing ancient scores and transferring new ones, this paper introduces a triple representation method for Guqin score knowledge using knowledge mapping technology. It transforms the simplified Guqin notation into a text format, exemplified by the Ming Dynasty’s “Magic Secret Score.” A computer-editable text corpus of Guqin is created, and various tags are applied to the text. A word cloud visualization of the “Magic Secret Score” text spectrum is generated using a word cloud tool. The frequency of different right-hand fingerings in the “Magic Secret Score” is analyzed. By examining the temporal characteristics of the music, the paper extracts the timing relationships of right-hand fingerings from the text corpus and identifies various performance templates using the KMP pattern matching algorithm. Specifically, it analyzes 64 different right-hand finger techniques. Additionally, the frequency of string combinations in the “Magic Secret Score” is recorded, providing essential guidelines for future intelligent music transfer reasoning. The experimental findings indicate that there are specific constraints on the timing of fingerings and string usage in musical tones, with the maximum length of reusable fingering timing templates being no more than 25.</p>Yiwen ZhangGenfang ChenSi YuZhouyu Tong

https://ojs.bbwpublisher.com/index.php/JERA/article/view/11456
<p>With the development of computer vision technology, panoramic image stitching has been widely used in fields such as scene reconstruction. A single traditional image cannot fully capture the panoramic view of the iconic East Gate of the South Campus of Shaanxi University of Technology. Therefore, this project aims to technically fuse multiple partial images into a complete panoramic image, enabling comprehensive recording and visual presentation of the architectural landscapes and spatial environments in this area. This report first introduces the technical background and application scenarios, clarifying the necessity of panoramic image stitching in campus landscape recording. It then elaborates on the core objectives and practical values, highlighting the role of technical solutions in improving image quality. Technically, a modular system design based on OpenCV is adopted, including modules such as image preprocessing, feature extraction and matching, image registration, fusion, and post-processing. Specifically, the SIFT algorithm is applied for feature extraction, KNN combined with ratio testing is used for feature matching, image registration is achieved by calculating the homography matrix, the fusion process utilizes multiband blending and Laplacian pyramid, and post-processing includes operations such as black area filling and CLAHE contrast enhancement. The experiment was conducted in a specific hardware and software environment using five overlapping images. After preprocessing, stitching, detail enhancement, and black edge repair, a panoramic image was successfully generated. The results show that the panoramic image fully presents the relevant scenery, with concealed seams, balanced exposure differences, and strong hierarchical details. This report provides a systematic description of the project’s technical implementation and achievement application.</p>Wuning XiJieyi Tan

https://ojs.bbwpublisher.com/index.php/JERA/article/view/11463
<p>With the proliferation of Android malware, the issue of traceability in malware analysis has emerged as a significant problem that requires exploration. By establishing links between newly discovered, unreported malware and prior knowledge from existing malware data pools, security analysts can gain a better understanding of the evolution process of malware and its underlying reasons. However, in real-world scenarios, analyzing the traceability of malware can be complex and time-consuming due to the large volume of existing malware data, requiring extensive manual analysis. Furthermore, the results obtained from such analysis often lack explanation. Therefore, there is a pressing need to develop a comprehensive automated malware tracking system that can provide detailed insights into the tracking and evolution process of malware and offer strong explanatory capabilities. In this paper, we propose a knowledge graph-based approach that uses partial API call graphs comprising semantic and behavioral features to reveal the traceability relations among malware and provide explainable results for these relations. Our approach is implemented on a dataset of over 20,000 malware samples labeled with family information, spanning a time period of 10 years. To address the challenges associated with the complexity of analysis, we leverage prior knowledge from existing malware research and a branch pruning method on call graphs to reduce computational complexity and enhance the precision of explanations when determining traceability relations.</p>Linna Wang

https://ojs.bbwpublisher.com/index.php/JERA/article/view/11452
<p>Miniature air quality sensors are widely used in urban grid-based monitoring due to their flexibility in deployment and low cost. However, the raw data collected by these devices often suffer from low accuracy caused by environmental interference and sensor drift, highlighting the need for effective calibration methods to improve data reliability. This study proposes a data correction method based on Bayesian Optimization Support Vector Regression (BO-SVR), which combines the nonlinear modeling capability of Support Vector Regression (SVR) with the efficient global hyperparameter search of Bayesian Optimization. By introducing cross-validation loss as the optimization objective and using Gaussian process modeling with an Expected Improvement acquisition strategy, the approach automatically determines optimal hyperparameters for accurate pollutant concentration prediction. Experiments on real-world micro-sensor datasets demonstrate that BO-SVR outperforms traditional SVR, grid search SVR, and random forest (RF) models across multiple pollutants, including PM<sub>2.5</sub>, PM<sub>10</sub>, CO, NO<sub>2</sub>, SO<sub>2</sub>, and O<sub>3</sub>. The proposed method achieves lower prediction residuals, higher fitting accuracy, and better generalization, offering an efficient and practical solution for enhancing the quality of micro-sensor air monitoring data.</p>Xingfu OuMiao ZhangWenfeng Chen

<p>In this paper, the optical efficiency and output thermal power of the heliostat mirror field are analyzed and optimized by constructing a geometric model and an optimization algorithm for the optimal design of the heliostat mirror field of a tower-type solar photovoltaic power plant. First, based on the solar position model and the optical efficiency model of the heliostat mirror field, the annual average optical efficiency, the annual average output thermal power, and the annual average output thermal power per unit mirror area of the heliostat mirror field are calculated. Secondly, the EB layout was used to optimize the heliostat field, and the parameters of heliostat size and mounting height were optimized by genetic algorithm and particle swarm algorithm to maximize the annual average output thermal power per unit mirror surface area. The results show that the optimized heliostat mirror field significantly increases the annual average output thermal power per unit mirror area under the condition of achieving the rated power, which provides theoretical basis and technical support for the design and operation of the tower solar thermal power plant.</p>Xinyu WuHongjun ZengHewen Wei

<p>In the context of the rapid iteration of information technology, the Internet of Things (IoT) has established itself as a pivotal hub connecting the digital world and the physical world. Wireless Sensor Networks (WSNs), deeply embedded in the perception layer architecture of the IoT, play a crucial role as “tactile nerve endings.” A vast number of micro sensor nodes are widely distributed in monitoring areas according to preset deployment strategies, continuously and accurately perceiving and collecting real-time data on environmental parameters such as temperature, humidity, light intensity, air pressure, and pollutant concentration. These data are transmitted to the IoT cloud platform through stable and reliable communication links, forming a massive and detailed basic data resource pool. By using cutting-edge big data processing algorithms, machine learning models, and artificial intelligence analysis tools, in-depth mining and intelligent analysis of these multi-source heterogeneous data are conducted to generate high-value-added decision-making bases. This precisely empowers multiple fields, including agriculture, medical and health care, smart home, environmental science, and industrial manufacturing, driving intelligent transformation and catalyzing society to move towards a new stage of high-quality development. This paper comprehensively analyzes the technical cores of the IoT and WSNs, systematically sorts out the advanced key technologies of WSNs and the evolution of their strategic significance in the IoT system, deeply explores the innovative application scenarios and practical effects of the two in specific vertical fields, and looks forward to the technological evolution trends.

2025-08-072025-08-079430330910.26689/jera.v9i4.11475A Study on the Distribution of Remaining Oil in Daqing S, P, and G Oil Layers at Different Flooding Stages
https://ojs.bbwpublisher.com/index.php/JERA/article/view/11480
<p>Extensive research has been conducted on remaining oil in the Daqing Oilfield during high water cuts’ late stage, but few studies have offered multi-level analyses from both macro and micro perspectives for remaining oil under varying formation conditions and displacement methods. This article focuses on the remaining oil in the S, P, and G reservoirs of Daqing Oilfield by employing the frozen section analysis method on the cores from the S, P, and G oil layers. The research identifies patterns among them, revealing that the Micro Remaining Oil types in these cores primarily include pore surface thin film, corner, throat, cluster, intergranular adsorption, and particle adsorption. Among these, intergranular adsorption contains the highest amount of remaining oil (the highest proportion reaches 60%) and serves as the main target for development potential. The overall distribution pattern of the Micro Remaining Oil in the S, P, and G oil layers shows that as flooding intensity increases, the amount of free-state remaining oil gradually decreases, while bound-state remaining oil gradually increases. The study also examines eight typical coring wells for macroscopic remaining oil, finding four main types in the reservoir: interlayer difference, interlayer loss, interlayer interference, and injection-production imperfect types. Among these, the injection-production imperfect type has the highest remaining oil content and is the primary target for development potential. Analyzing the reservoir utilization status and oil flooding efficiency reveals that as water flooding intensifies, the oil displacement efficiency of the oil layer gradually decreases, while the efficiency of oil layer displacement improves. Strongly flooded cores exhibit less free-state remaining oil than weakly flooded cores, making displacement more challenging. This study aims to provide a foundation and support for the development of remaining oil in the S, P, and G oil layers.</p>Zhaoming Yang

https://ojs.bbwpublisher.com/index.php/JERA/article/view/11468
<p>Temporal optics, which enables lossless manipulation of ultrafast pulses, offers a new dimension for the regulation of quantum optical fields. In this paper, we established a temporal Fourier transform (TF) system based on a four-wave mixing (FWM) time lens and constructed a full quantum theoretical model for the resulting temporal SU(1,1) interferometer. This interferometer has high temporal resolution, can impose interference in both time and frequency domains, and is sensitive to the phase derivative. By introducing linear time-varying phase modulation, we achieved sub-picosecond precision in temporal autocorrelation measurements and generated an optical frequency comb with a fixed interval based on a feedback iteration mechanism. Theoretical analysis reveals the crucial regulatory role of time-frequency coupling in quantum interference, providing novel solutions for ultrafast quantum imaging, temporal mode encoding, and the generation of optical frequency quantization.</p>Tianyu LiuZepeng Liu
