This article presents a multiresonant gate driver (MRGD) for wide bandgap (WBG) devices. The design carries out a Monte Carlo analysis that incorporates a sensitivity analysis-based optimization technique for MRGDs, designed to drive WBG power MOSFETs. This is applicable to resonant power converters and resonant switched-mode power supply (SMPS). Unlike standard numerical design approaches that are reported in previous studies, the proposed approach streamlines the design process and shortens the product development time by using manufacturer SPICE models. The proposed design and optimization are simulated in LT SPICE, optimizing the key parameters that affect the multiresonant filter’s frequency response. The MRGD aims to maximize operational efficiency at high frequencies when used in SMPS and resonant power converters. The proposed concepts are assessed and validated through a hardware prototype. With the help of simulation and hardware verification, the MRGD demonstrated improved efficiency, achieving a 34.8% reduction in gate drive losses compared to an off-the-shelf conventional voltage-source gate driver (VSGD).

Contact-Free Sensing of Stability in Vector Fields of Vibratory Dynamical Systems 振动动力系统矢量场稳定性的无接触传感

This article introduces a contact-free sensing (CFS) framework for stability analysis of vibratory dynamical systems via extracted motion vector fields (EMVf) inherent in near infrared (NIR) video frame sequences. Unlike traditional stability metrics (e.g., Amer et al., Lyapunov, and Gromov–Hausdorff), the CFS approach uses the Krantz criterion to measure stability via a required versus actual upper bound on the eigenvalues of the motion vector fields extracted from NIR frame sequences. The experimental results use the CFS framework to demonstrate a reduction in the maximum eigenvalue from $left|lambda_{max }right|$ > 1 (unstable EMVf before modulation) to $left|lambda_{max }right|$ ≤ 1 (stable EMVf) after modulation. The main novelties in contract-free monitoring of vibratory systems reported in this article are as follow: 1) adjustable time lag between system motion recorded in NIR video frame sequences, 2) ease with which vibratory motion instability is detected whenever the maximal eigenvalue of an EMVf exceeds a required upper bound limit, and 3) straightforward means of measuring the difference between Hamilton characteristics of recorded EMVfs that occur at different times. This noncontact method eliminates sensor-induced artifacts and offers real-time stability for industrial applications in vibratory mechanical (e.g., bounded vibration of a pile driver monitored with an NIR camera) and biomechanical systems (e.g., bounded variation in rehabilitating walker motion).
本文介绍了一种无接触传感(CFS)框架,通过提取近红外(NIR)视频帧序列中固有的运动矢量场(EMVf)来分析振动动力系统的稳定性。与传统的稳定性指标(例如,Amer等人,Lyapunov和Gromov-Hausdorff)不同,CFS方法使用Krantz准则通过从近红外帧序列中提取的运动矢量场的特征值的所需与实际上界来测量稳定性。实验结果利用CFS框架证明了最大特征值从$left|lambda_{max }right|$ >.1(调制前的不稳定EMVf)降低到$left|lambda_{max }right|$≤1(调制后的稳定EMVf)。本文报道的振动系统无合同监测的主要新颖之处如下:1)在近红外视频帧序列中记录的系统运动之间的可调时滞;2)每当EMVf的最大特征值超过所需的上限时,即可轻松检测到振动运动不稳定性;3)测量不同时间发生的记录EMVf的汉密尔顿特性之间差异的直接方法。这种非接触式方法消除了传感器引起的伪影,并为振动机械(例如,用近红外摄像机监测的打桩机的有界振动)和生物力学系统(例如,康复步行者运动的有界变化)的工业应用提供了实时稳定性。

This article presents an edge-AI-enabled adaptive genetic algorithm (GA)-optimized fuzzy logic controller (AGA-FLC) for a positive output super lift relift Luo converter (POSLRLC), developed for energyefficient and stable operation in renewable-powered electric vehicle (EV) charging stations. The converter mitigates nonlinear and high-gain dynamics by integrating fuzzy inference with real-time GA-based optimization, implemented on an FPGA-based edge computing platform. The proposed controller dynamically tunes fuzzy membership functions and rule weights to ensure optimal duty-cycle regulation under varying solar input and load conditions. Simulation and hardware-in-loop validation demonstrate superior dynamic response with a rise time of 15 ms, settling time of 28 ms, and peak overshoot below 3%. The system achieves an efficiency of 95.8% and maintains a THDv of 2.1%, fully compliant with IEC 61000-3-2 Class A harmonic limits. FPGA synthesis results indicate 62.8% look-up table (LUT) utilization, 1.8-W on-chip power, and 21-ns latency. Monte Carlo robustness testing (10 000 runs) confirms 100% compliance with performance criteria across ±10% parameter variations. The proposed AGA-FLC provides a scalable and intelligent control solution for next-generation EV charging systems and smart grid infrastructures.

Wireless body area networks (WBANs) are one of the most essential technologies for today's electronic healthcare to achieve real-time monitoring and remote medical treatment in cloud-assisted environments. However, secure and efficient authentication is still a big challenge due to the constrained capabilities of WBAN devices. While many existing solutions use elliptic curve cryptography (ECC), it might introduce excessive computational and communication overheads. The work describes a lightweight authentication protocol for WBAN based on hyperelliptic curve cryptography (HECC), an emerging ECC substitute to address these limitations. HECC ensures the same security with shorter key sizes and reduced computation overhead, and thus is even more appropriate for resource-constrained environments. The proposed protocol is comprehensively analyzed for security and has been proven secure against various known attacks while fulfilling the necessary authentication requirements. Performance analysis indicates that the presented scheme attains considerable computational time savings, communication overhead, and storage, which indicates its feasibility and efficiency in secure healthcare systems.
无线体域网络(wban)是当今电子医疗保健在云辅助环境中实现实时监控和远程医疗的最基本技术之一。然而,由于WBAN设备性能的限制,安全高效的认证仍然是一个很大的挑战。虽然许多现有的解决方案使用椭圆曲线加密(ECC),但它可能会带来过多的计算和通信开销。该工作描述了一种基于超椭圆曲线加密(HECC)的WBAN轻量级认证协议,这是一种新兴的ECC替代品,可以解决这些限制。HECC通过更短的密钥大小和更少的计算开销来确保相同的安全性,因此更适合资源受限的环境。提出的协议进行了全面的安全性分析,并已被证明对各种已知攻击是安全的,同时满足必要的身份验证要求。性能分析表明,该方案节省了大量的计算时间、通信开销和存储,表明其在安全医疗保健系统中的可行性和有效性。

Environmental aspects are largely affected by power generation and consumption. The Indian economy is based on the agriculture sector, where electric motors play a vital role in this application as a pump. Induction motors with the International Efficiency (IE3) standard are in use at present, which lags in efficiency. Revitalizing these motors for the next generation is a paramount importance among researchers. Super-premium and ultra-premium (IE4 and IE5, respectively) motors are the way to go in these applications for reduced power consumption. This article provides the design aspects of those three motors with in-depth electromagnetic and thermal studies. The authors believe that this will lead the researchers and the industry designers to move beyond the requirements of the energy-efficient induction motors.

In this article, we develop generative models that generate embeddings for graph nodes while using only their initial features without any knowledge about their neighborhoods and connections. Accordingly, we start by generating reference embeddings using a graph neural network (GNN) trained on full graph knowledge. Afterward, we train the generative models, specifically an autoencoder and a generative adversarial network (GAN), which use only the initial node features to generate close and almost indistinguishable embeddings to those generated by the GNN. To this end, we use a customized loss function acting as a strong regularization for our models. It compels them to generate only embeddings with small error values from those generated by the fully fledged model. Using real-world graph datasets, we evaluate the quality of the generated embeddings for different similarity metrics such as the mean-squared error (MSE) and cosine similarity. We also assess their ability in reconstructing an initial graph and predicting the neighborhood of each newly added node. Results show the superiority of the proposed generative models over the conventional ones and that the proposed GAN model outperforms the proposed autoencoder with an efficiency in graph reconstruction exceeding 85% for different datasets.
在本文中,我们开发了生成模型,该模型仅使用图节点的初始特征而不了解其邻域和连接,从而生成图节点的嵌入。因此,我们首先使用经过全图知识训练的图神经网络(GNN)生成参考嵌入。然后,我们训练生成模型,特别是一个自动编码器和一个生成对抗网络(GAN),它们仅使用初始节点特征来生成与GNN生成的嵌入接近且几乎无法区分的嵌入。为此,我们使用自定义损失函数作为模型的强正则化。它迫使他们只从完全成熟的模型生成的嵌入中生成具有小误差值的嵌入。使用真实世界的图形数据集,我们根据不同的相似度指标(如均方误差(MSE)和余弦相似度)评估生成的嵌入的质量。我们还评估了它们在重建初始图和预测每个新添加节点的邻域方面的能力。结果表明,所提出的生成模型优于传统的生成模型,并且GAN模型在不同数据集的图重构效率超过85%,优于所提出的自编码器。

Robust face recognition under partial occlusions remains a key challenge in real-world biometric and surveillance systems. In this article, we propose a hybrid dual-branch model—channel-spatial faster vision transformer (CSFVIT)—that integrates local and global feature processing to enhance recognition performance under diverse occlusion scenarios. The local branch refines facial features using a parallel channel-spatial attention (PCSA) module based on ResNet-18, while the global branch leverages a faster vision Transformer (FasterViT) to capture long-range dependencies. A dynamic attention fusion (DAF) module adaptively balances these features based on occlusion severity. We validate our model on five benchmark datasets: CASIA-WebFace, LFW, Extended Yale B, ORL, and AR. The model achieves 97.46% accuracy on CASIA-WebFace, 97.62% on LFW, 99.39% on Extended Yale B, 98.78% on ORL, and 98.50% on AR (sunglasses)/97.50% (scarf), consistently outperforming state-of-the-art baselines. CSFVIT achieves consistently high recognition accuracy under both synthetic and real-world occlusions, outperforming several attention- and transformer-based baselines. This practical and efficient architecture demonstrates strong potential for real-world face recognition applications in unconstrained environments.
在现实世界的生物识别和监测系统中,部分遮挡下的鲁棒人脸识别仍然是一个关键挑战。在本文中,我们提出了一种混合的双分支模型-通道-空间快速视觉转换器(CSFVIT),它集成了局部和全局特征处理,以提高在不同遮挡场景下的识别性能。局部分支使用基于ResNet-18的并行通道空间注意(PCSA)模块来细化面部特征,而全局分支利用更快的视觉变压器(FasterViT)来捕获远程依赖关系。动态注意力融合(DAF)模块根据遮挡严重程度自适应平衡这些特征。我们在五个基准数据集上验证了我们的模型:CASIA-WebFace, LFW, Extended Yale B, ORL和AR。模型在CASIA-WebFace上达到97.46%的准确率,在LFW上达到97.62%,在Extended Yale B上达到99.39%,在ORL上达到98.78%,在AR(太阳镜)上达到98.50% /97.50%(围巾),始终优于最先进的基线。CSFVIT在合成和现实世界的遮挡下都能保持较高的识别精度,优于几种基于注意力和变压器的基线。这种实用和高效的架构展示了在不受约束的环境中真实世界人脸识别应用的强大潜力。

The proliferation of interconnected mobile devices within densely packed cloud networks necessitates sophisticated frameworks for capacity optimization to ensure efficiency, reliability, and data security. This study explores the challenges posed by user mobility, dynamic calculations, and increasing service demands in edge computing environments. We propose a novel capacity optimization algorithm (COA) that leverages a deep autoencoder-based binary bat algorithm to improve resource allocation. The system uses the SHA- 512 cryptographic hash function for capacity requests (CRs), facilitating seamless user access to resources while quickly detecting and revoking access for unauthorized users. The system employs a selective routing mechanism that considers specific service requirements, allowing it to prioritize user demands and maximize resource utilization. The quality of service (QoS) integration ensures consistent, high-quality performance for mobile nodes, leading to an improved user experience. The framework’s effectiveness is evaluated through experiments, demonstrating its ability to optimize throughput and reduce interference in multinode networks.

Data-Driven Cyberattack Detection Based on Deep Learning for Power Cyber–Physical Systems 基于深度学习的电力网络物理系统数据驱动网络攻击检测

The cyberthreats faced by power cyber–physical systems (CPSs) have become increasingly serious. However, existing cyberattack detectors still cannot resist them effectively due to the data imbalance, the high false alarm rate (FAR), and highly covert cyberattacks. To address the issues, this article proposes a novel data-driven cyberattack detector based on deep learning for power CPSs. The proposed detector is equipped with two Wasserstein generative adversarial networks (WGANs), which overcome the data imbalance issue in existing detectors by synthesizing adequate abnormal samples involving cyberattacks. Moreover, a novel substation-level detector with a modified light gradient boosting machine (LightGBM) and a maximal information coefficient (MIC) unit is introduced into the proposed detector. It captures differences between abnormal sampled values caused by cyberattacks and natural faults, thus reducing the FAR. Furthermore, a novel overalllevel detector based on an improved graph convolutional neural network (IGCNN) is built for the proposed detector. It performs spatial–temporal topology mining on complete power CPS graphs to fully extract more comprehensive attack-related features than existing detectors, thus realizing exhaustive detection sensitive enough to highly covert cyberattacks. Finally, the effectiveness and superiority of the proposed detector are verified by experimental research on actual power data from China.
电力网络物理系统(cps)面临的网络威胁日益严重。然而,由于数据不平衡、虚警率(FAR)高、网络攻击的隐蔽性高,现有的网络攻击检测器仍然不能有效地抵抗它们。为了解决这些问题,本文提出了一种基于深度学习的新型数据驱动网络攻击检测器。该检测器配备了两个Wasserstein生成对抗网络(wgan),通过合成涉及网络攻击的足够异常样本,克服了现有检测器的数据不平衡问题。此外,还引入了一种新型变电所级探测器,该探测器采用了改进的光梯度增强机(LightGBM)和最大信息系数(MIC)单元。它捕获由网络攻击和自然故障引起的异常采样值之间的差异,从而降低FAR。在此基础上,构建了一种基于改进的图卷积神经网络(IGCNN)的全局检测器。它对完全幂次CPS图进行时空拓扑挖掘,以充分提取比现有检测器更全面的攻击相关特征,从而实现对高度隐蔽的网络攻击足够敏感的穷尽检测。最后,通过对国内实际功率数据的实验研究,验证了所提检测器的有效性和优越性。

This article presents an empirical study on the integration of natural language processing (NLP) into inventory management systems to improve operational efficiency within e-commerce and supply chain contexts. Traditional inventory systems often face limitations in handling unstructured data and providing timely decision support. To address these challenges, a modular framework incorporating NLP, machine learning, and a hybrid database architecture is proposed and evaluated. The system enables users to interact through natural language queries, which are translated into improved SQL commands using semantic parsing and Transformer models. Performance evaluation using real-world and synthetic datasets demonstrates significant improvements in query execution time, demand prediction accuracy, and inventory optimization. Comparative results indicate that the NLP-based system outperforms conventional systems in both cost-efficiency and responsiveness. The findings demonstrate the potential of NLP-based inventory systems to improve data interaction and predictive analytics across supply chain operations.
