Smart Helmet - Intelligent Safety Helmet

open access: yesInternational Journal of Advanced Research in Science, Communication and Technology, 2021
Bike riding is a lot of fun, but accidents happen. People choose motorbikes over cars as it is much cheaper to run, easier to park and flexible in traffic. In India, more than 37 million people are using two wheelers. Since usage is high, accident percentage of two wheelers are also high compared to four wheelers.

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...
