This project demonstrates how to interface an HC-SR04 ultrasonic distance sensor with an SSD1306 OLED display using the STM32 Blue Pill microcontroller. The system measures distances and displays them ...

We present a revised distance to the nearby galaxy NGC 6822 using a new multi-band fit to both previously published and new optical, near-, and mid-infrared data for Cepheid variables. The new data ...

Abstract: A new type of coplanar capacitance sensor was designed to address the problem that coplanar capacitance sensors are difficult to use for measuring and characterizing defects at different ...

Abstract: Construction machinery has been widely used to upgrade the power industry. Nevertheless, high-voltage and high-current operational conditions necessitate stringent safety distance protocols.

Dark matter will help explain not only how our universe was made, but also its components. It will help people understand fundamental physics and how additional particles and forces exist. The ...
