http://ijaers.com/ Open Access international Journal to publish research paper en-us August Fruit diseases impact global agricultural output, quality, and sustainability. Manual visual inspection by agricultural experts is time-consuming, subjective, and inaccurate, especially in large-scale farming. AI and DL have shown promise in automating plant disease diagnosis using image-based analysis. In particular, Convolutional Neural Networks (CNNs) can extract complicated visual characteristics and accurately diagnose disease signs. A CNN-based system for fruit disease diagnosis and symptom identification utilizing image-based datasets is proposed in this paper. The study aims to create an automated system that can efficiently classify healthy and unhealthy fruits and identify illness symptoms using visual interpretation. We use picture collections of healthy and damaged fruit samples from agricultural libraries. Data augmentation, normalization, and scaling were performed on images. Multiple convolutional, pooling, batch normalization, and fully connected layers in a TensorFlow-Keras CNN architecture learn disease-specific characteristics. Analyses include accuracy, precision, recall, F1-score, and confusion matrix analysis after Adam optimizer training. Gradient-weighted Class Activation Mapping (Grad-CAM) visualizes classification-influencing symptom areas. According to the analysis, the suggested framework has 96.4% classification accuracy, precision, recall, and F1-score values above 95%. The Grad-CAM visualizations show disease-affected lesions, spots, discolouration, and rotting areas, improving model interpretation. Analysis shows that the CNN framework outperforms traditional machine learning and rudimentary deep learning models. In conclusion, the suggested framework for automated fruit disease diagnosis and symptom identification is accurate, dependable, and explainable. The study shows that CNN-based systems can aid precision agriculture, crop health monitoring, and disease management. http://ijaers.com/detail/a-hypothetical-cnn-based-framework-for-disease-detection-and-symptom-identification-using-image-based-datasets/ S.

Indra Gandhi http://ijaers.com/uploads/issue_files/1IJAERS-0720264X-AHypothetical.pdf Faced with growing electricity demand, the frequency regulation capacity of traditional thermal power units is limited and difficult to meet the current power system. Combining thermal power units with energy storage facilitates flexibility upgrades by leveraging the ultra-fast response characteristics inherent to such system. The method of joint dispatching of thermal power and energy storage systems is called combined thermal and energy storage. This study develops a theoretical model of thermal-storage combined frequency regulation to analyze system dynamic responses. Combining lithium battery and flywheel energy storage systems with 1000MW thermal power units, a simulation model for dynamic frequency regulation and peak shaving was built in MATLAB/Simulink. The simulation experiments showed that the cooperative control strategy could enhance frequency regulation capacity and also improve the stability of thermal power units. http://ijaers.com/detail/comparison-of-thermal-storage-combined-power-generation-with-traditional-thermal-power-frequency-modulation-and-generator-output/ Lei Huang, Qiang-Sheng Xiao, Yan-Zuo Chang http://ijaers.com/uploads/issue_files/2IJAERS-0720266X-Comparison.pdf
