This issue includes three articles, the first titled “New Categories for Phase-Resolved Partial Discharge Pattern Classification,” by Contin, Piccolo, and Cavallini. It presents a refined framework for analyzing phase-resolved partial discharge (PRPD) patterns in insulation diagnostics. The study questions the traditional one-to-one link between PRPD shapes and defect types, proposing three new categories: voltage-dependent, multiple, and ambiguous patterns. This is to better represent the changing nature of discharge phenomena. By testing insulation systems rated between 4 and 18 kV, including porous tape insulation and four-layer mica tapes, the authors show how PRPD patterns develop under different voltage levels, aging conditions, and stress factors. Examples include distributed micro-void discharges that change from “rabbit-ear” to rounded shapes, symmetric in polarity and phase. The article emphasizes the limitations of relying only on pattern shape for diagnosis and recommends additional localization techniques such as antenna probes and ultrasound detectors. This work is especially valuable for those seeking to improve the reliability of insulation evaluation and develop more advanced pattern-recognition systems for rotating electrical machines.
本期包括三篇文章,第一篇题为“相位分解局部放电模式分类的新类别”,作者是Contin、Piccolo和Cavallini。它提出了一个精细的框架来分析相分辨局部放电(PRPD)模式在绝缘诊断。该研究质疑传统的PRPD形状和缺陷类型之间一对一的联系,提出了三个新的类别:电压依赖性,多重和模糊模式。这是为了更好地表现放电现象的变化性质。通过测试额定在4至18 kV之间的绝缘系统,包括多孔带绝缘和四层云母带,作者展示了PRPD模式在不同电压水平、老化条件和应力因素下的发展情况。例如,分布式微孔放电从“兔耳”形状变为圆形,极性和相位对称。文章强调了仅依靠模式形状进行诊断的局限性,并推荐了额外的定位技术,如天线探针和超声探测器。这项工作对于那些寻求提高绝缘评估可靠性和开发更先进的旋转电机模式识别系统的人尤其有价值。

To address the synergistic challenges of energy efficiency and security in wireless sensor networks (WSNs) under complex attack environments, this article proposes a collaborative energy efficiency and security enhancement (CEESE) routing algorithm. During the clustering phase, an enhanced particle swarm optimization (PSO) method is introduced, which integrates the golden sine algorithm (Gold- SA) and Levy flight (LF) to balance the global exploration and local exploitation through sine perturbations and random long-hop mechanisms. A multiobjective fitness function is constructed, considering node residual energy, comprehensive trust values, and communication distance, thereby achieving the energy-balanced cluster head (CH) election. In the routing phase, a hybrid trust model combining direct and indirect trust is designed, which collaborates with deep Q (DQ)-learning to enable real-time path state awareness and dynamic maintenance. Simulation results demonstrate that CEESE achieves the superior performance across varying network scales and attack scenarios. Specifically, in a 100-node, 100 × 100 m monitoring area, the first node death round of CEESE improved by 37.8%, 36.9%, 14.7%, 10.4%, and 7.1% compared with TAOSC-MHR, MRCH, EEHCHR, DST-WOA, and CTRF algorithms, respectively. Its advantages persist in a large-scale network with 500 nodes within a 200 × 200 m area. Regarding security, under a black-hole attack involving 50% malicious nodes, CEESE achieves a packet delivery rate (PDR) 19.2%–59.3% higher, a malicious node detection rate (DR) 5.7%–28.1% higher, and an average delay 14.3%–46.5% lower than the compared algorithms. This study provides an efficient routing solution for energy-constrained WSN applications with stringent security requirements.
为了解决复杂攻击环境下无线传感器网络(WSNs)能效和安全的协同挑战,本文提出了一种协同能效和安全增强(CEESE)路由算法。在聚类阶段,引入了一种增强粒子群优化(PSO)方法,该方法将金正弦算法(Gold- SA)和Levy飞行(LF)相结合,通过正弦扰动和随机长跳机制平衡全局探索和局部开发。构建了考虑节点剩余能量、综合信任值和通信距离的多目标适应度函数,实现了能量平衡簇头(CH)的选举。在路由阶段,设计了直接信任和间接信任相结合的混合信任模型,并结合深度Q (deep Q)学习实现实时路径状态感知和动态维护。仿真结果表明,该算法在不同的网络规模和攻击场景下都能取得优异的性能。其中,在100个节点、100 × 100 m的监测区域内,CEESE算法比TAOSC-MHR、MRCH、EEHCHR、st - woa和CTRF算法分别提高了37.8%、36.9%、14.7%、10.4%和7.1%的第一个节点死亡轮。在200 × 200 m的范围内有500个节点的大型网络中,其优势依然存在。在安全性方面,在恶意节点占比50%的黑洞攻击情况下,CEESE算法的报文投递率(PDR)比两种算法高19.2% ~ 59.3%,恶意节点检测率(DR)比两种算法高5.7% ~ 28.1%,平均时延比两种算法低14.3% ~ 46.5%。该研究为能量受限且安全要求严格的WSN应用提供了一种高效的路由解决方案。

This article investigates the role of plasma support electromagnetic (EM) interactions and surface plasmon polariton (SPP) in enhancing the performance of terahertz (THz) wireless body area networks (WBANs) for consumer health applications. A bending log-periodic graphene-based antenna is proposed, comprising multiple log-periodic graphene elements excited through a silver nanostrip feedline to support plasmonic wave confinement. The antenna demonstrates dual-band operation at 5.95 and 6.31 THz, where the excitation of SPP modes leads to strong field localization and reduced propagation losses. The antenna exhibits impressive return loss values of −47.71 and −24.27 dB at 5.95 and 6.31 THz, respectively, ensuring minimal signal reflection. The front-to-back ratio (FBR) is 11.12, with an efficiency of 81% and 50.7% the antenna achieves a directivity of 10.14 dBi. It is ensuring reliable performance in plasma-mediated THz propagation. Bending analysis validates structural robustness under realistic WBAN conditions, while a three-layered human body model is employed to assess the specific absorption rate (SAR), confirming low exposure levels suitable for long-term wearable and implantable applications. Further, computer simulation technology (CST), HSS, and ADS results have been verified and validated using mathematical modeling. The integration of plasma-driven SPP mechanisms with graphene antenna technology highlights a pathway toward high-performance THz WBANs, enabling safe and continuous health monitoring through smart textiles and advanced biomedical platforms.
本文研究了等离子体支持电磁(EM)相互作用和表面等离子体激元(SPP)在增强用于消费者健康应用的太赫兹(THz)无线体域网络(wban)性能方面的作用。提出了一种弯曲对数周期石墨烯天线,该天线由多个对数周期石墨烯元素组成,通过银纳米带馈线激发以支持等离子体波约束。该天线在5.95 THz和6.31 THz双频段工作,其中SPP模式激发导致强场定位和降低传播损耗。该天线在5.95 THz和6.31 THz下的回波损耗值分别为- 47.71和- 24.27 dB,确保了最小的信号反射。前后比(FBR)为11.12,效率为81%,50.7%,天线的指向性为10.14 dBi。它确保了等离子体介导的太赫兹传播的可靠性能。弯曲分析验证了实际WBAN条件下的结构鲁棒性,而三层人体模型用于评估比吸收率(SAR),确定了适合长期可穿戴和植入式应用的低暴露水平。此外,计算机仿真技术(CST)、HSS和ADS的结果已经通过数学建模进行了验证和验证。等离子体驱动的SPP机制与石墨烯天线技术的集成突出了实现高性能太赫兹wban的途径,通过智能纺织品和先进的生物医学平台实现安全连续的健康监测。

This article presents a digital demodulation technique for use in galvanic-coupling intrabody communication (GC IBC) with binary phase shift keying (BPSK)-modulated signals at low frequencies (below megahertz). The technique relies on a direct oversampled acquisition of the BPSK-modulated signal with an analog-to-digital converter (ADC) associated with an original digital processing algorithm to extract the demodulated data from the acquired samples. The originality of the solution resides in the digital processing algorithm, which combines several mechanisms to fully exploit the redundancy present in the collected samples in order to provide a high degree of robustness, while maintaining a low level of complexity compatible with efficient implementation in a microcontroller. Simulation and measurement results are presented, confirming the robustness of the proposed solution. In particular, hardware measurements carried out under controlled conditions demonstrate very good performance, with a bit error rate (BER) below 3 × 10−5 for a signal with a signal-to-noise ratio (SNR) of −5 dB. The proposed solution is also validated under real conditions with a galvanic-coupling (GC) communication realized through the back muscle of a fish, resulting in a BER < 2.5 × 10−6.
本文提出了一种用于低频(兆赫以下)双相移键控(BPSK)调制信号的电偶体内通信(GC - IBC)的数字解调技术。该技术依赖于bpsk调制信号的直接过采样采集,使用与原始数字处理算法相关联的模数转换器(ADC)从采集的样本中提取解调数据。该解决方案的独创性在于数字处理算法,该算法结合了几种机制,以充分利用在所收集的样本中存在的冗余,以提供高度的鲁棒性,同时保持低水平的复杂性,与微控制器中的有效实现兼容。仿真和测量结果验证了该方法的鲁棒性。特别是,在受控条件下进行的硬件测量显示出非常好的性能,对于信噪比(SNR)为- 5 dB的信号,误码率(BER)低于3 × 10−5。该方案在实际条件下也得到了验证,通过鱼的背部肌肉实现了电偶耦合(GC)通信,得到的误码率< 2.5 × 10−6。

We conducted an in-depth investigation into the impact of conditional variational autoencoders (CVAEs) and Bayesian neural networks (BNNs) on high dynamic range (HDR) image reconstruction. A parallel multiattention module (PMAM) is introduced in the improved YOLOv10 framework to enhance computational efficiency and detection performance. To reconstruct HDR images, we enhance the asynchronous Kalman filter (AKF) algorithm to improve image detail quality. We introduce BNN and CVAE into the AKF algorithm to reduce noise effects and improve the logarithmic intensity of the reconstructed image. The BNN estimates noise covariance, thereby reducing its impact during the reconstruction process. Simultaneously, the CVAE leverages polarity as a conditional input, and uses spatial and temporal information through a CVAE to generate more accurate logarithmic image intensities. In the object detection stage, we integrate a parallel module combining the self-attention mechanism and the ECA module to improve training efficiency without increasing the number of parameters. This PMAM module, based on improved YOLOv10, strengthens the model’s ability to capture global and channel-specific features. Finally, the proposed method’s accuracy and robustness are validated through extensive simulations and comparative experiments. Comprehensive experiments on public datasets show that our model achieves 81.32% mAP@0.5 and 59.67% mAP@[0.5:0.95], demonstrating significant improvements in detection accuracy and image reconstruction quality.
我们深入研究了条件变分自编码器(CVAEs)和贝叶斯神经网络(BNNs)对高动态范围(HDR)图像重建的影响。在改进的YOLOv10框架中引入了并行多注意模块(PMAM),提高了计算效率和检测性能。为了重建HDR图像,我们对异步卡尔曼滤波(AKF)算法进行了改进,以提高图像的细节质量。我们在AKF算法中引入了BNN和CVAE,以降低噪声影响,提高重建图像的对数强度。BNN估计噪声协方差,从而减少其在重建过程中的影响。同时,CVAE利用极性作为条件输入,并通过CVAE使用空间和时间信息来生成更精确的对数图像强度。在目标检测阶段,我们将自注意机制与ECA模块相结合的并行模块集成在一起,在不增加参数数量的前提下提高了训练效率。该PMAM模块基于改进的YOLOv10,增强了模型捕捉全局和特定频道特征的能力。最后,通过大量的仿真和对比实验验证了该方法的准确性和鲁棒性。在公共数据集上的综合实验表明,我们的模型达到了81.32% mAP@0.5和59.67% mAP@[0.5:0.95],在检测精度和图像重建质量上有了显著提高。
