The Borassus flabellifer husk, with its cross-linked, hollow cylindrical structure and a density of 0.74 g/cm³, is lightweight and exhibits low water absorption (47.25%) and moisture regain (4.41%), enhancing weathering resistance. These properties make it a competitive alternative to bio-fibers like jute and sisal for lightweight engineering applications.

Composite (DMA): This study examines the alkali treatment effect on Borassus husk fiber-reinforced epoxy composites. Alkali treatment improves mechanical properties, including increased storage modulus, glass transition temperature, and damping factor, especially for 0.75-h treated fiber/epoxy composite. Alkali-treated/epoxy composites show enhanced thermos-mechanical stability and vibration damping, making them suitable for aerospace and automotive applications.

Deep-learning techniques were applied in this study. EfficientNetB3, MobileNetV2, and InceptionV3 were employed to assess their effectiveness in detecting melanoma. Among these architectures, EfficientNetB3 emerged as the standout performer, achieving an exceptional accuracy rate of 90.7% and an impressive area under the curve (AUC) score of 97%. A cascading combination technique was utilized to develop a multi-architecture model by combining the output of all the individual models. This reduced the computational cost of the model and enhanced the efficiency of the model for melanoma detection.

This study aims to analyze the age related characteristics of malaria in human host by exploring Caputo fractional order models with temperature variability, that is looked into the combined effects of fractional order and temperature variability on malaria dynamics. MATLAB was used to simulate Caputo fractional order with temperature variability and to apply the Adams–Bashforth–Moulton numerical approach.

This study presents the design of a novel secondary controller for Automatic Generation Control (AGC) in multi-area; multi-source power systems incorporating an appropriate generating rate constraint (GRC) has been considered for the hydro and thermal power plants. The proposed controller, optimized using the Grey Wolf Optimizer (GWO) algorithm, improves AGC performance in systems integrating hydro-thermal. The controller's effectiveness is demonstrated through enhanced dynamic response, reduced frequency deviations, and better load handling. The optimization process fine-tunes the controller parameters to ensure superior performance and robustness under varying operational conditions.

Numerical simulation to study the extraction and storage mechanism of three types of gas reservoirs: (1) Low-permeability gas reservoirs: Competing adsorption and pressurization to replenish energy.
