Design and improved performance of gate stacked dual material gate all around nanowire field effect transistor with spacer based underlap extension Hina Ismat, Singam Aruna, Srinivasa Naik K, B Balaji Engineering Research Express, 2026 This work presents the design and optimization of a gate-stacked underlap-engineered silicon nanowire MOSFET (GSUESNW-MOSFET) with an HfO 2 spacer for the 10-nm technology node. The electric field generated by the device work function difference at the metal-to-metal interface in the gate stacking is coupled to the nanowire channel through the HfO 2 spacer. This coupling becomes significant when the electric field maximum at the channel drain extension terminal is reduced. The reduction in electric field increases the tunneling width (w) and effectively suppresses lateral band-to-band tunneling (L-BTBT) component of Gate-Induced Drain Leakage (GIDL) in the proposed structure. The underlap extension regions in the proposed device will reduce the electric field penetration from the drain to the channel, thereby suppressing drain-induced barrier lowering (DIBL). Using 3D TCAD simulations, the work demonstrates that the OFF-state current is reduced from 6.43 × 10 −10 Amp to 2.01 × 10 −11 Amp, and the I on to I off ratio is increased from 3.45 × 107 to 3.91 × 108 for a 10 nm channel length at an oxide thickness of 2 nm. The I on to I off ratio is 3.91 × 108 with a high transconductance of 2.97 mS μm −1 , Subthreshold Swing (SS) of 79 mV dec −1 , even though the channel length is scaled down to 10 nm. Extensive Technology Computer-Aided Design (TCAD) simulations show the superior performance of the proposed GSN MOSFET structure over conventional nanowire, Nanowire with Underlap, and Nanowire with Underlap HfO 2 spacer, indicating its potential for low-power and high-performance nanoscale applications.
Designing a New Potato and Banana Disease Detection Using Trans-Unet++ and Classification Through Gather-Excite Network Divyakanti Rongali, Sasibhushana Rao Gottapu, Aruna Singam 2026 6th International Conference on Advances in Electrical Computing Communications and Sustainable Technologies Icaect 2026, 2026 Banana was one of the most widely cultivated fruits across the world, yet its yield were heavily impacted each year by various leaf diseases. Detecting these diseases at an early stage is essential for improving overall production. Potato farming also suffered from similar challenges, as pests reduce the quality and yield of the harvested crops. Thus, the reduction in quantity and quality led to reduced income for farmers, because of trade restrictions, limited market access, and price drops. There are various factors, which affect the degradation of agricultural products. Hence, minimizing plant diseases is essential for ensuring higher crop quality and improved farming efficiency. So, a new potato and banana disease detection technique is suggested in this research work with a deep learning technique. In the initial phase, essential images needed for the validation is collected from the benchmark resources. Next, the collected images are given to the disease detection phase using Transformer Unet++ (Trans-Unet++). Then, the disease detected images are given to the disease classification phase. Here, the potato and banana diseases are classified using Gather-Excite Network (GENet). At last, multiple experiments are carried out in the developed framework over classical mechanisms to verify its efficiency.

MSFCS-Net: A Dual-Decoder Architecture for an Efficient Segmentation of Optic Disc and Optic Cup Kowju Gayatri, Birendra Biswal, Singam Aruna IETE Journal of Research, 2026 Fundus photography significantly enhances the detection mechanism of ophthalmic conditions that affect the vision of the eye. One of these conditions, Glaucoma, which is widely known as the silent thief of vision, is due to its subtle signs in causing vision loss. Precise localisation of the Optic Cup (OC) & Optic Disc (OD) from retinal images enhances the diagnostic accuracy of Glaucoma. Thus, to develop an automated model, this research proposes a Multi-Scale Feature-driven Condition-based Segmentation Network (MSFCS-Net), an improved Deep Convolutional Neural Network (DCNN) that elevates the segmentation efficiency by learning feature maps of several sizes using a multi-scale encoder. In this paper, the Residual Depth-wise Separable Convolution Module (RDSCM) is employed to preserve spatial information, reducing the hyperparameter size to mitigate the burden of computational complexity. Furthermore, a Triple Attention Mechanism (TAM) is integrated to elevate the pertinent feature maps, enabling the network to achieve high intra-class variance between the pixel values of different classes. Additionally, a novel condition-based segmentation mechanism is proposed to control the segmentation of the OC using the predicted maps of the OD via a dual decoder of the MSFCS-Net. This model has shown a remarkable improvement in the segmentation of OD and OC regions when validated with different publicly available datasets such as REFUGE, Rim-One, and ORIGA, for accurate diagnosis of Glaucoma. The MSFCS-Net model achieved an average accuracy of 99.67, an intersection over union of 99.34 and a Dice coefficient of 99.66 on the ORIGA, outperforming the existing models with the proposed model.
Advanced Plant Disease Classification Using Trans-R2UNet Segmentation and Gabor Dilated CNN with Spatial Attention Rongali Divyakanti, Gottapu Sasibhushana Rao, Singam Aruna Ingenierie Des Systemes D Information, 2025 The rapid growth of plant disease has influenced the economy of the developing nation by minimizing crop productivity.Conventional plant disease categorization approaches were hard to implement and consumed more time for processing, which made the classification task more complicated.Moreover, due to the increasing global population, implementing advanced technology in the field of agriculture is essential to guarantee continuous food supply for future generations.Currently, to perform plant disease detection, deep learning approaches are implemented since they offer more accurate detection outcomes within a short duration.However, they demand for huge volume of data and resources for processing.Therefore, it is essential to design an effective model to offer generalized outcomes in plant disease classification and to overcome the complexities of the classical networks.Initially, the raw plant leaf images are collected from the standard resource.Later, the collected images are offered to the designed Transformer-based Recurrent Residual U-Net (Trans-R2UNet) to perform plant disease segmentation.Then, the segmented images are subjected directly to the classification system.Here, the classification is carried out using the Gabor Dilated Convolutional Neural Network with Spatial Attention (GDCNN-SA).The proposed GDCNN-SA achieved CSI values of 37.14 and an accuracy of 98.55%.But, the existing GDCNN had 10.79 CSI values and 82.02% accuracy.Further, the proposed Trans-R2UNet had 0.268 accuracy in segmentation, thus significantly improving disease detection.The experimental evaluation demonstrated that the designed system obtained superior results in classifying the plant disease.Overall, the proposed work promotes sustainable environmental modeling and data-driven environmental assessments.
Designing a New Tomato Leaf Disease Classification Framework using RAN-based Adaptive Fuzzy C-Means with Heuristic Algorithm Model Rongali Kanti, Gottapu Sasibhushana Rao, Singam Aruna Serbian Journal of Electrical Engineering, 2025 In tomato production, one of the most significant problems is the identification of Tomato Leaf Disease (TLD). Plant leaf disease is the primary factor that influences both the quality and quantity of crop production. India holds the second position in tomato making. However, multiple diseases contribute to the decline in the quality of tomatoes and the decrease in crop yield. Hence, it is important to accurately categorize and diagnose the tomato plant leaf infection. The productions of tomatoes are impacted by many leaf diseases. Early recognition of the diseases helps to reduce the disease infection and improve the yield of crops. Certain diseases are identified and classified using several methods. Therefore, the TLD classification and identification model is developed to solve the above problems. The images related to tomato leaves are aggregated in the initial phase through online sources. Then, the images are forwarded to the pre-processing phase. Further, the pre-processed image is given to the segmentation process, where the Adaptive Fuzzy C-Means (AFCM) technique is utilized. Meanwhile, the parameters of the AFCM algorithm complicate the cluster assignment in the presence of outliers or noise, thus resulting in reduced clustering performance. So, the parameters of AFCM are tuned by utilizing the new improved algorithm named Dingo Optimization Algorithm (DOA) to improve the clustering accuracy. It is done by assuming the AFCM parameters as a population of Dingoes and the maximum classification accuracy as its fitness function. Finally, the segmented images are fed to the classification process, where the Residual Attention Network (RAN) is used to attain the classified outcomes. Therefore, the investigated system shows a more efficient TLD prediction rate compared to traditional techniques in the experimental investigation. The results from the experiments indicate that the suggested models exhibit exceptional classification performance, achieving an accuracy rate of 95.22%. Therefore, the model suggests advancement in predictive capabilities over traditional methods.
LINEAR ARRAY DESIGN WITH DOLPH-CHEBYSHEV METHOD FOR HIGH GAIN AND SIDE-LOBE REDUCTION IN IoT APPLICATIONS A. Srinag, Singam Aruna, Kethavathu Srinivasa Naik Telecommunications and Radio Engineering English Translation of Elektrosvyaz and Radiotekhnika, 2025 The paper introduces a linear array design utilizing the Dolph-Chebyshev method, aiming for high gain while minimizing side-lobe levels for internet of things (IoT) applications. The approach offers a balance between the parameters, enabling the attainment of the narrowest beam width for a specified side-lobe level and vice versa. While various methods exist for reducing side-lobe levels to conserve power and enhance service quality, this study focuses on a 7-element array using the Dolph-Chebyshev method. Comparative analyses of resulting patterns across different side-lobe levels reveal that increased gain and directivity are not necessarily achieved with reduced side-lobe levels. The microstrip comb-line antenna array tailored for 5 GHz IoT applications is implemented on a Rogers RO4003C substrate measuring 200 &times; 50 mm<sup>2</sup>, with a gain of 13 dBi. The side-lobe levels achieved are below -18 dB at 5 GHz.
