This project demonstrates a low-cost intelligent traffic signal system using Arduino and ultrasonic sensors to reduce congestion caused by fixed-timer traffic lights. Four HC-SR04 sensors detect ...

This readme provides instructions on how to build / use a Meshtastic I2C sensor in both host and client modes. There are two PlatformIO environments available as examples to build off of: kb2040_host ...

Abstract: To address the issues of high miss and false detection rates in defect detection of PV (photovoltaic) module visible light images under imbalanced data conditions, an improved data ...

Abstract: The vortex polarization direction indicator (Vortex-PDI), comprising a half-wave vortex retarder and an analyzer, enables single-shot characterization of linearly polarized light. This study ...
