Wireless Solar Charging Systems for Electric Vehicles: Technology, Design, and Implementation Challenges
Abstract: Higher standards for the ease, safety, and dependability of electric vehicle (EV) charging have been proposed in recent years due to the new energy sector's electrical vehicle (EV) rapid development. Inductive coupling is used for wireless power charging. Both stationary and dynamic situations can be used for inductive coupling. Low energy loss and reduced demands on the primary circuit are achieved by rearranging the transformer and changing the high frequency. …

Optimizing Fin Parameters to Enhance Passive Heat Dissipation in Photovoltaic Panels
Abstract: This study explores passive cooling techniques to enhance the thermal management of photovoltaic (PV) modules, which is crucial for maintaining efficiency. A computational fluid dynamics (CFD) model, using ANSYS Fluent, was developed to evaluate three fin shapes: rectangular, trapezoidal, and triangular, attached to the back of PV modules. The study varied parameters such as fin count, thickness, and length to determine optimal configurations for cooling. Among the designs, triangular fins …

The Role of Adaptive Filters in Enhancing Acoustic Echo Cancellation Efficiency in Noisy Environments
Abstract: The novel approach that this work discusses is a DCD-based iterative learning filter approach improved with deep learning methodologies, designed to improve the efficiency of acoustic echo cancellation. The proposed system can really manage both linear and nonlinear echo scenarios, dynamically adapting to fluctuating acoustic environments. The above comparative evaluations with standard filter, the standard RLS filter, indicate that the mean square error, and the standard deviation of the correlation …
