Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Abstract: Stable operation of transformers is vital for the security of power grids. And the partial discharges can lead to insulation degradation and potential transformer failures. This paper ...

Exceptional points (EPs) in non-Hermitian systems offer a strong response to perturbations, offering a promising platform for sensing. By using a third-order EP of coherent perfect absorption, here, ...
