This paper addresses the challenge of commonmode voltage (CMV) generation in three-phase two-level back-to-back converters, which are a significant source of electromagnetic interference (EMI) in variable-speed drive (VSD) applications. The rapid switching in these converters often produces high CMV, inducing damaging shaft voltages in motor bearings and requiring costly EMI filtering to meet electromagnetic compatibility (EMC) standards. A novel pulsewidth modulation (PWM) strategies are proposed in two steps and evaluated to reduce CMV amplitudes without compromising inverter performance. These strategies operate by controlling the switching sequences of both rectifier and inverter, effectively limiting CMV to two distinct levels: ± 23 V d c, ± 13 Vdc. Simulation results demonstrate significant CMV reductions for each method, validating their effectiveness and practical feasibility. This work provides a promising approach to improving the EMI profile of back-to-back converters used in industrial drives, high-voltageDC transmission, and renewable energy systems, with applications in electric vehicles and microgrids. © 2025 IEEE.

Preservation of the crops depends on early and accurate detection of pests on crops as they cause several diseases decreasing crop production and quality. Several deep-learning techniques have been applied to overcome the issue of pest detection on crops. We have developed the YOLOCSP-PEST model for Pest localization and classification. With the Cross Stage Partial Network (CSPNET) backbone, the proposed model is a modified version of You Only Look Once Version 7 (YOLOv7) that is intended primarily for pest localization and classification. Our proposed model gives exceptionally good results under conditions that are very challenging for any other comparable models especially conditions where we have issues with the luminance and the orientation of the images. It helps farmers working out on their crops in distant areas to determine any infestation quickly and accurately on their crops which helps in the quality and quantity of the production yield. The model has been trained and tested on 2 datasets namely the IP102 data set and a local crop data set on both of which it has shown exceptional results. It gave us a mean average precision (mAP) of 88.40% along with a precision of 85.55% and a recall of 84.25% on the IP102 dataset meanwhile giving a mAP of 97.18% on the local data set along with a recall of 94.88% and a precision of 97.50%. These findings demonstrate that the proposed model is very effective in detecting real-life scenarios and can help in the production of crops improving the yield quality and quantity at the same time.

This paper presents a adaptable multilevel inverter design utilizing the Packed E-Cell (PEC) configuration. This topology is well-suited for converting energy generated by photovoltaic systems to power AC loads and for use in uninterruptible power supplies (UPS). Key benefits of this inverter include a reduced requirement for power switches and gate drivers compared with traditional inverters, as well as a simplified control system. By positioning the shunt capacitors horizontally, both can be charged and discharged simultaneously to one-fourth of the input source. Consequently, with two isolated input sources, the inverter achieves the output voltage with 17 levels. A simple level-shifted pulse width modulation (LS-PWM) technique is employed to regulate the operation of the inverter. The performance and use of the multilevel inverter are verified through MATLAB-based simulations. © 2025 IEEE.

All wireless communication systems are moving towards higher and higher frequencies day by day which are severely attenuated by rains in outdoor environment. To design a reliable RF system, an accurate prediction method of rain attenuation is established and used globally based on local rain intensity measurement. Required rain intensity used for attenuation prediction is generally measured at a point with 1-min integration time or converted from higher integration time to 1-min. Recent measurements of rain intensity with a 10-second integration time indicate that intensity is not uniform over a 1-minute duration. Consequently, the statistics of rain intensity distribution and attenuation predictions are influenced by measurements with integration times shorter than 1 minute. It has been established that an integration time of 0.01% provides the optimal fit for actual rain rate data. This paper presents the rain intensity distributions from data measured with 2-min, 1-min, 30-sec, 20-sec, and 10-sec integration times, and it has impact on rain rate distributions as well as rain attenuation predictions. © 2025, Electromagnetics Academy.

Lung cancer is the most lethal form of cancer. This paper introduces a novel framework to discern and classify pulmonary disorders such as pneumonia, tuberculosis, and lung cancer by analyzing conventional X-ray and CT scan images called lung cancer risk prediction (LCRP) model. LCRP has four modules, namely data collection and preprocessing, data augmentation module, image segmentation module, and prediction module. Actually, LCRP employs three deep learning models;sequential model, functional model, and transfer model on publicly available training datasets. Convolutional neural networks (CNNs) have emerged as a highly effective field in machine learning, particularly for image datasets in the field of biomedical applications. The primary goal is to validate these models by comparing their performance with other models in order to determine their effectiveness in addressing challenging datasets. Our research has revealed a noteworthy enhancement in the efficiency of binary and multi-class classification using mask R-CNN image segmentation. During the model training process, a combination of Adam and stochastic gradient descent dual optimizers has been used to improve performance. LCRP have outperformed current pre-trained models by minimizing training parameters, computational costs, and overhead. It introduces 98.5% accuracy, 88.7% specificity, 89% sensitivity, 89.2% precision, and 89.09% F-measure. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2025.

Optical and Quantum Electronics 2025年第2期57卷 1-17页

In this article, a renovated patch array antenna is developed that achieves features such as high gain and circular polarization by introducing a bi-layered eight-shaped metasurface on top of the feed. The antenna is designed as a dual-feed array structure, utilizing silicon materials for the substrates and featuring two gold patches operating at frequencies of different dimensions with two orthogonal feeds optimized to achieve wide bandwidth operation. Along with modifying the gaps and arcs in the antenna, circular polarization can be made possible with an appropriate pattern of the unit cell. Finally, a designed eight-shaped metasurface has been used to control wave propagation, improve polarization switching properties, and increase the bandwidth of impedance and also axial ratio. The substrates of the renovated patch antennas and that of the bi-layered metasurface are respectively made of silicon and silicon dioxide to reduce undesired waves. Different Components are separated from each other with silicon material without an air gap. The impedance bandwidth covers a wide range of frequencies from 3.24 to 5.44 THz, about 50%. The results show that the axial ratio is in four ranges (3.48–3.74 THz), (4.08–4.16 THz), (4.23–4.27 THz) and (5.05-6 THz), which are in good coverage with the impedance bandwidth. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.

Due to the wealth of information accessible on many insurance issues, including travel and auto insurance, individuals are becoming more and more impacted by these kinds of insurance in today's society. But this tendency also makes room for dishonest practices. Insurance fraud is harmful and unlawful, regardless of who commits it - the vendor or the customer. Fraud can come from both the customer and the vendor. The consumer may commit fraud by filing exaggerated claims or using out-of-date policies, while the vendor may market insurance from phoney firms or neglect to submit premiums. This paper presents a comparative analysis of various classification algorithms, including Support Vector Machine (SVM), Random Forest (RF), Decision Tree (DT), Linear Regression (LR), and Polynomial Regression, for detecting insurance fraud. The performance of these algorithms is evaluated using key metrics such as Precision, Recall, and F1-Score. The analysis reveals that the bestperforming model is the Random Forest, with a Mean Squared Error (MSE) of 6.50, outperforming the other techniques. © 2025 IEEE.
