Elnazerhanyinghui@ucas.ac.cnYinghui Hanhanyinghui@ucas.ac.cn<p>The valorization of nitrous oxide (N<sub>2</sub>O) as an oxygen atom donor presents an attractive opportunity for green chemistry applications, leveraging both its industrial abundance and thermodynamically favorable oxidation potential. However, practical implementation has been constrained by the inherent kinetic inertness and poor coordinating ability of N<sub>2</sub>O. While prior studies achieved N<sub>2</sub>O-mediated conversion of aryl halides to phenols, such transformations necessitated stoichiometric chemical reductants and elevated pressure (2 atm), posing challenges in operational safety and process scalability. This study focuses on an electrochemical strategy that enables efficient oxygen atom transfer under ambient pressure through controlled current application. This methodology facilitates the selective transformation of aryl iodides to phenols without external reducing agents, establishing an environmentally benign synthetic pathway.

To mitigate these challenges, a novel enhancement approach is proposed, integrating Local Adaptive Color Correction (LACC) with contrast enhancement based on adaptive Rayleigh distribution stretching and CLAHE (LACC-RCE). Conventional color correction methods predominantly employ global adjustment strategies, which are often inadequate for handling spatially varying color distortions. In contrast, the proposed LACC method incorporates local color analysis, tone-weighted control, and spatially adaptive adjustments, allowing for region-specific color correction. This approach effectively enhances color fidelity and perceptual naturalness, addressing the limitations of global correction techniques. For contrast enhancement, the proposed method leverages the global mapping characteristics of the Rayleigh distribution to improve overall contrast, while CLAHE is employed to adaptively enhance local regions. A weighted fusion strategy is then applied to synthesize high-quality underwater images. Experimental results indicate that LACC-RCE surpasses conventional methods in color restoration, contrast optimization, and detail preservation, thereby enhancing the visual quality of underwater images. This improvement facilitates more reliable inputs for underwater object detection and recognition tasks.</p>2025-03-28T09:25:53+08:00Copyright (c) 2025 Author(s)https://ojs.bbwpublisher.com/index.php/JERA/article/view/9957Leveraging Green AI Technology to Build Sustainable Schools: A Conceptual Model Based on AI Agents2025-04-02T10:21:30+08:00Yiting Qiubarbaraqiu@dingtalk.comYihan Lubarbaraqiu@dingtalk.comGuoqing Xiabarbaraqiu@dingtalk.comMd Munir Hayet Khanbarbaraqiu@dingtalk.comDeshinta Arrova Dewibarbaraqiu@dingtalk.com<p>The integration of Green Artificial Intelligence (AI) technologies into educational systems offers a promising avenue to enhance operational efficiency while addressing sustainability challenges.

Given the problems of single loss reduction measure, lack of economy, and practicality in existing research, this paper proposes an optimization method of distribution network loss reduction based on tabu search algorithm and optimizes the combination and parameter configuration of loss reduction measure. The optimization model is developed with the goal of maximizing comprehensive benefits, incorporating both economic and environmental factors, and accounting for investment costs, including the loss of power reduction. Additionally, the model ensures that constraint conditions such as power flow equations, voltage deviations, and line transmission capacities are satisfied. The solution is obtained through a tabu search algorithm, which is well-suited for solving nonlinear problems with multiple constraints. Combined with the example of 10kV25 node construction, the simulation results show that the method can significantly reduce the network loss on the basis of ensuring the economy and environmental protection of the system, which provides a theoretical basis for distribution network planning.</p>2025-04-02T13:50:44+08:00Copyright (c) 2025 Author(s)https://ojs.bbwpublisher.com/index.php/JERA/article/view/10009The Application of Machine Vision in Defect Detection Systems2025-04-02T14:08:21+08:00Peihang Zhongzhangry010129@163.comJiawei Linzhangry010129@163.comMuling Wangzhangry010129@163.com<p>With the rapid development of computer vision technology, artificial intelligence algorithms, and high-performance computing platforms, machine vision technology has gradually shown its great potential in automated production lines, especially in defect detection.

Tracking the training history reveals that misclassified samples often exhibit high confidence and excessive uncertainty in the early stages of training. To address this issue, we propose an uncertainty-based robust sample selection strategy, which combines confidence error with RandAugment to improve image diversity, effectively reducing overfitting caused by uncertain samples during deep learning model training. To validate the effectiveness of the proposed method, extensive experiments were conducted on FER public benchmarks. The accuracy obtained were 89.08% on RAF-DB, 63.12% on AffectNet, and 88.73% on FERPlus.</p>2025-04-03T15:58:42+08:00Copyright (c) 2025 Author(s)https://ojs.bbwpublisher.com/index.php/JERA/article/view/10156Study on Preparation and Forming of TiC Steel-Bonded Cemented Carbide Paste for Direct Writing Printing2025-04-10T10:15:05+08:00Zhi Wangzhiwang_stdu@126.comBing Xuzhiwang_stdu@126.comJiawei Yuanzhiwang_stdu@126.comXiang Jie Chengzhiwang_stdu@126.comTing Pu Yuezhiwang_stdu@126.comMei Ye Zhangzhiwang_stdu@126.comSheng Hui Zhouzhiwang_stdu@126.com<p>TiC steel-bound cemented carbide body was prepared by direct writing printing.

Sigma-Delta modulator, as the most important component of high-precision ADC, is widely used in high-quality audio, high-precision instrument measurement, and other fields due to its advantages of high precision, strong noise resistance, and low hardware cost. This article designs a discrete structure third-order four-bit high-precision Sigma-Delta modulator through modeling, with an oversampling rate set to 512. Under ideal conditions, the simulation results show that the SDNR reaches 152.7db and the ENOB is 25.24bits. After introducing non-ideal noise, the system performance has decreased. The simulation results show that the SDNR is as high as 124.5db and the ENOB is 20.39bits.

We employ a manifold-based optimization approach, leveraging exponential and logarithmic mappings to transform rotation vectors into rotation matrices. The proposed ESKF framework ensures state variables remain near the origin, effectively mitigating singularity issues and enhancing numerical stability. Additionally, due to the small magnitude of state variables, second-order terms can be neglected, simplifying Jacobian matrix computation and improving computational efficiency. Furthermore, we introduce a novel Kalman filter gain computation strategy that dynamically adapts to low-dimensional and high-dimensional observation equations, enabling efficient processing across different sensor modalities. Specifically, for resource-constrained UAV platforms, this method significantly reduces computational cost, making it highly suitable for real-time UAV applications.</p>2025-04-03T16:52:16+08:00Copyright (c) 2025 Author(s)https://ojs.bbwpublisher.com/index.php/JERA/article/view/10094Design of Differential Signal Processing Circuitry for Single-Frequency Laser Interferometry Displacement Measurement2025-04-03T17:00:17+08:00Songxiang Liuyanjingping_8@163.comJingping Yanyanjingping_8@163.comCan Tangyanjingping_8@163.com<p>This thesis addresses the issues existing in traditional laser tracking displacement measurement technology in the field of ultraprecision metrology by designing a differential signal processing circuit for high-precision laser interferometric displacement measurement.
