Data Driven Controller Design For Distributed Power Sources In Microgrid
Abstract: AbstractUsing renewable power sources requires controlled procedures to accomplish satisfactory stabile levels of power transmission and keep up with grid power deviation. Additionally, these methodologies in a perfect world require no pre-information of the grid structure, and as meagre correspondence with neighbouring power sources as would be prudent. As a next stride, we concentrate on how the power can be dispatched from different power hotspots for enhanced grid productivity. Microgrids …

ML-Enhanced Self-Healing Fiber-Reinforced Polymer Composites with Embedded IoT Sensors for Damage Prediction
Abstract: Fiber-reinforced polymer (FRP) composites are widely used in aerospace and structural systems; nevertheless, the potential for microcracking and fatigue-induced performance degradation remains an obstacle with respect to improved service life. Traditional self-healing methods, while performing well on a chemical level, often lack real-time diagnostic awareness and adaptive control. To circumvent this, we developed a machine-learning augmented self-healing FRP composite, in which a DCPD–Grubbs catalytic matrix was combined with IoT sensor …

Reformation of WLAN Feeler by Incorporating Varactor Diode with Negative Media Structure
Abstract: AbstractIn this manuscript, authors proposed a negative media structure with Varactor diode to reform the rectangular microstrip patch antenna parameter to a great extent. Initially basic feeler was designed and simulated, and then parameters were enhanced by implementing negative media structure. It has been observed that negative media is not sufficient to improve the parameters therefore Varactor diode was introduced to get the required improvement. This proposed design of feeler …
