The persistent challenges faced by sun-tracking systems include inefficient power production, wastage of energy, ineffective control, and high costs. Most of the existing systems are either static or dual-axis tracking which lead to inefficient output or increasing energy wastage and cost overheads. Though, single-axis tracking system has some benefits over the static or dual-axis tracking, most of the systems do not analyze the selection of optimal sun-path which again leads to inefficient and inadequate absorption of sunlight. Addressing the issues, this article presents a design of optimal parameters for single-axis solar-tracking by analyzing the sun-path and tracking vector dynamics. The study mainly focuses on analyzing solar-tracking dynamics, variations in sunray angles, Azimuth and Elevation dynamics throughout the day for the twelve months, Sun-vector calculation for local coordinates, joint rotational-axis, and joint motion control using a Proportional-Derivative controller. Additionally, the article outlines a conceptual architecture for automated control, monitoring, and power distribution for the potential development of a sustainable smart city. The proposed strategy addresses the issues of the optimal design of a single-axis solar-tracker, thus ensuring the reduction of cost overhead and energy wastage. © 2024 IEEE.

Secrecy Performance Review for IoT-based Cognitive Farming System

Recent Patents on engineering 2024年第7期18卷 66-75页

作者： Chopra, Khyati Alam, M. Afshar Department of CSE Jamia Hamdard University New Dehli India University School of Automation and Robotics GGSIPU New Delhi110032 India Department of Computer Science and Engineering Jamia Hamdard University New Delhi110062 India

Smart farm management has complex challenges;therefore, there is a need to improve the overall adaptability, profitability, and environmental soundness of the farming systems. Agricultural production can be enhanced with the help of IoT-based cognitive tools. The rapid increase in IoT-based smart systems has raised critical concerns about efficiently utilizing the wireless spectrum. To drastically bring the improvement in the utilization of the wireless spectrum, cognitive radio (CR) has emerged as an effective solution. The inherent openness and broadcast nature of the wireless medium have given rise to many security issues in cooperative networks. Information-theoretic security or physical layer security (PLS) is evolved as an efficacious wireless prototype for reliable transmissions to avert the eavesdropper from expropriating transmittal data on the wireless connections. Security is the key factor in these networks as they are exposed and active in be-havior, thus, are susceptible to fraudulent activities. In this patent study, we investigated the performance of the CR system in terms of secrecy and also examined the system in terms of diversity receipt and selection of relay. The secrecy outcome of channel state information at the sender was also studied. The detrimental effects of fading in cooperative networks were also extensively discussed. Cooperative diversity was examined by deploying MRC and SC strategies at receptors. It has been deduced that CSI knowledge at the sender also has an eloquent concussion on the secrecy of the cognitive system. © 2024 Bentham science Publishers.

Data Augmentation via Face Morphing for Recognizing Intensities of Facial Emotions

IEEE Transactions on Affective Computing 2023年第2期14卷 1228-1235页

Being able to recognize emotional intensity is a desirable feature for a facial emotional recognition (FER) system. However, the development of such a feature is hindered by the paucity of intensity-labeled data for model training. To ameliorate the situation, the present study proposes using face morphing as a novel way of data augmentation to synthesize faces that express different degrees of a designated emotion. Such an approach has been successfully validated on humans and machines. Specifically, humans indeed perceived different levels of intensified emotions in these parametrically synthesized faces, and FER systems based on neural networks indeed showed improved sensitivities to intensities of different emotions when additionally trained on the synthesized faces. Overall, the proposed data augmentation method is not only simple and effective but also useful for building FER systems that recognize facial expressions of mixed emotions. © 2010-2012 IEEE.

Endoscopy images pose a distinct set of challenges, such as specularity, uniformity, and deformation, which can obstruct surgeons’ observations and decision-making processes. These hurdles complicate feature extraction and may ultimately lead to the failure of a surgical navigation system. To tackle these obstacles, we introduce a Modified Maximal Stable Extremal Region (MMSER) detector that specifically targets fine specular regions. Subsequently, we ingeniously fuse the capabilities of MMSER and saturation region properties to precisely identify specular regions within endoscopy images. Furthermore, our approach harnesses the shared properties of covariant features and endoscopic imaging to detect features in intricate regions, such as low-textured and deformed areas. Surpassing contemporary methods, our proposed technique demonstrates remarkable performance when evaluated on the available CVC-ClinicSpec datasets. Our method has shown improvements in accuracy, recall, f1-score, and Jaccard index by 0.21%,25.42%,7.77% snd 11.77%, respectively, when compared to recent techniques. Owing to its exceptional ability to accurately pinpoint specular regions and extract features from complex areas, our approach holds the potential to significantly advance surgical navigation. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

In the process of reconstructing images from data acquired within a limited angular range, we encounter what is termed limited-angle tomography. The deficiency of complete data in this context results in artifacts, commonly appearing as streaks or missing structures, which can significantly compromise the quality of the reconstructed slice. This degradation gives rise to issues such as boundary distortion, blurred edges, and intensity bias, potentially leading to misinterpretation of the images. Hence, addressing artifacts in limited-angle tomography is crucial for clinical applications. Although deep learning-based reconstruction has shown impressive results in recent times, concerns about its robustness persist. To bolster the robustness of our proposed technique, we integrate prior information from a modified U-net with preprocessed input into the Relative Variation - Simultaneous Algebraic Reconstruction Technique (RV-SART) to provide insights into unmeasured data. Subsequently, the method extracts structure from the initially reconstructed slice through structure-texture decomposition. This process facilitates the reconstruction of high-quality CT images while suppressing pattern-like artifacts. Extensive experiments demonstrate that our approach surpasses both traditional and state-of-the-art learning techniques in terms of reconstruction quality and preservation of fine structures in noisy limited-angle reconstruction problems. Our technique provides improvements over the recent LRIP-net for a 90-degree scanning range in quantitative metrics such as PSNR by 17.48%, RMSE by 46.36%, and SSIM by 6.18%. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Stress, a pervasive psychological state, profoundly impacts individuals' well-being and may lead to various health issues. In this paper, the WESAD (Wearable Stress and Affect Detection) dataset serves as the primary data source, from which HRV (Heart Rate Variability) data extracted using PPG (Photoplethysmography) sensor is utilized. This data can be obtained in a non-invasive method and is instrumental in this analysis. The dataset comprises HRV data from 15 individual test subjects obtained from PPG sensors, providing a crucial foundation for the detection and classification of individuals into 'stressed' or 'not stressed' categories, thus offering a valuable tool for stress monitoring. This paper is a focused exploration into the CNN (Convolutional Neural Network) Deep Learning model, in which the feature selection process is carried out using Random Forest resulting in the selection of HR (Heart Rate), LF_BOXCOX (Low-Frequency Component - Box-Cox Transformed), MEDIAN_RR (Median of RR Intervals), SDI_BOXCOX (Standard Deviation 1 - Box-Cox Transformed), and SDRR_REL_RR (Standard Deviation of Relative RR Intervals) to optimize the model's performance. The model aims at advancing and refining stress detection methodologies to enhance overall well-being and achieves an accuracy of 98%. © 2024 IEEE.
