Convolutional neural networks can effectively extract representative features from high-dimensional data such as images and videos, and capture spatial information in the data, making it easier to locate aluminum defects. Moreover, running CNN model inference on local hardware has high real-time performance. Due to the advantages of convolutional neural network in anomaly detection, an improved CenterNet aluminum surface defect detection method was proposed. The algorithm combines common convolution and depthwise separable convolution to design a lightweight convolution module. Then, the Convolutional Block Attention Module is added to the feature extraction network to make the network better capture the rich input feature information of the image. Ultimately, the α-DIoU loss function is implemented to enhance the precision of bounding box predictions. The experimental findings demonstrate that the proposed algorithm achieves an average detection accuracy (mAP) of 86.02%, which is 5.95% higher than the average detection accuracy of the traditional algorithm, and has a good detection effect on aluminum surface defects. Furthermore, there is an 11.9% reduction in model parameters and a 15.2% decrease in floating-point computations, which helps to promote the deployment of embedded device platforms. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.</p>","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 3","pages":"415-421"},"PeriodicalIF":1.0,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143111132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In-network caching an integral part of ICN can reduce the shortcomings of today's location-based internet paradigm. As ICN has limited caching capability, the decision of optimal routing and content placement are the major challenges. In this study, we suggest a hybrid caching with a dynamic forwarding (<i>HCDF</i>) strategy which takes advantage of the off-path hash routing scheme and on-path caching scheme. To facilitate both caching schemes, a fraction of the caching space is allotted in each cache node for local caching. At the user-end segment, an estimation-based content placement (ECP) policy is designed using content popularity state and cache node position. This policy helps to cache popular content near the consumer's location using the shared cache space. At the server-end segment, the <i>HCDF</i> scheme dynamically selects the most appropriate routing strategy among three strategies (symmetric, asymmetric, and multicast) based on hop count and path stretch. To demonstrate the effectiveness of <i>HCDF</i>, extensive simulation on real-world internet topologies has been carried out. From our investigation, it is observed that the suggested approach exhibits an impressive performance in terms of cache hit, latency, and average link load compared to other standard hash routing and well-known on-path caching schemes. © 2024 The Author(s). <i>IEEJ Transactions on Electrical and Electronic Engineering</i> published by Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.</p>","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 6","pages":"920-933"},"PeriodicalIF":1.0,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tee.24251","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, designing a system in which multiple ECUs and sensors cooperate through an in-vehicle network requires knowledge not only of the network itself but also of embedded systems. Consequently, such design is a difficult task for beginners with insufficient knowledge. This study uses an approach in which the above knowledge is concealed and connections to the in-vehicle network are supported in a plug-and-play manner. The system, designated as the Complex Automotive Network Vanquishing Assistance System (CANVAS), is proposed. Even beginners are able to connect the ECUs and the sensors to an in-vehicle network using CANVAS without consideration of differences in the I/Fs adopted in the sensors and coding drivers for them. After presenting the CANVAS configuration, ease of connection was confirmed based on the time necessary to connect various distance sensors to a mobile robot with CANVAS.

In this paper, the electric field distribution of arc interrupter under simulated lightning impulse overvoltage is studied. It is found that the instantaneous electric field intensity is at a high level and the electric field uniformity is poor under lightning impulse. In order to further improve the electric field distribution of the interrupter, this paper proposes a method based on the combination of neural network and particle swarm optimization (PSO) to optimize the important structural parameters of the interrupter. A neural network model was established with suspension shield length (<i>L</i>₁), suspension shield radius (<i>R</i>₁), end shield radius (<i>R</i>₂), contact plate thickness (<i>H</i>₁) and end shield length (<i>H</i>₂) as inputs, and the maximum electric field strength and the uniformity of electric field on both sides of the static and dynamic contacts as outputs, respectively.

It plays a very important role in the maximum power point tracking of PV array and the improvement of micro-grid and at the same time further affects the sustainable development of new energy sources. In order to reduce the impact of gross errors on the results of parameter estimation, Correntropy based parameter estimation for PV array model under partial shading conditions is structured for robust estimation. In view of the fact that traditional particle swarm optimization (PSO) algorithm tends to converge prematurely and has poor local optimization capabilities and it is hard to resolve nonlinear parameter estimation problems with many nonlinear constraints, an algorithm (IPSO_SQP) that combines the improved particle swarm optimization (IPSO) algorithm with sequential quadratic programming (SQP) is proposed to identify the parameters of photovoltaic (PV) arrays under partial shading conditions. to recognize the parameters of PV array under partial shading conditions. The algorithm optimizes the performance of conventional algorithms by introducing nonlinear dynamic updating of inertia weights and learning factors, as well as the Cauchy mutation operator. It is reflected in the use of improved nonlinear iterative formulations to balance the global and local search capabilities of the algorithm, followed by the introduction of the Cauchy mutation operator to avoid the algorithm from falling into local optima and satisfy the nonlinear constraints to obtain a better solution. After simulation and experimental tests, the results indicate that the IPSO_SQP algorithm has high performance and precision in the robust parameter estimation of PV array model under partial shading conditions. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.</p>","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 6","pages":"899-909"},"PeriodicalIF":1.0,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, we propose Cantor, a novel dynamic source-gird-load-storage dispatching model for multiple objectives in a regional-level power system. Cantor incorporates two techniques: (1) An identification algorithm of dispatching time points (IDTP) is designed to satisfy the requirement of power supply–demand alignment dynamically.

This study examined whether persistence of the effects is dependent on the baseline autonomic conditions. The depressed subjects are known to frequently exhibit autonomic dysregulation, and were enrolled in the present study to test this hypothesis. Autonomic activity was evaluated using heart rate variability (HRV) analysis. Heart rate (HR) was measured using R-R intervals of the electrocardiogram in the resting state before and after the 20-min ELF-EF treatment (30 kV, 60 Hz) in the patients with major depressive disorder and in the control subjects, and HRV was analyzed using frequency-domain power spectrum analysis of R-R interval trend. Sham treatment was conducted in the control subjects but not in the patients due the ethical restriction. In the patients with depression, high-frequency variation (HF) related to breathing-dependent parasympathetic activity was low before the 60-Hz EF treatment and increased to the control level after treatment. No effects of EF were found for low-frequency variation (LF), LF/HF, and HR. The results indicated that acute 60-Hz EF treatment increased parasympathetic activity in the depressed subjects, who showed a reduction in baseline parasympathetic activity. This study suggests that the effects of ELF-EF treatment on autonomic activity are dependent on the baseline autonomic conditions. Future studies with larger sample sizes, incorporating sham treatment in the patients with depression, are needed to confirm these observations. © 2024 The Author(s). <i>IEEJ Transactions on Electrical and Electronic Engineering</i> published by Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.</p>","PeriodicalId":13435,"journal":{"name":"IEEJ Transactions on Electrical and Electronic Engineering","volume":"20 5","pages":"749-753"},"PeriodicalIF":1.0,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/tee.24240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
