YOLO-ADual: A Lightweight Traffic Sign Detection Model for a Mobile Driving System
Traffic sign detection plays a pivotal role in autonomous driving systems.The intricacy of the detection model necessitates high-performance hardware.Real-world traffic environments exhibit considerable variability and diversity, posing challenges for effective feature extraction by the model.Therefore, it is imperative to develop a detection model
Return glider radiosonde for in situ upper-air research measurements
Upper-air balloon soundings for weather predictions have been made since the beginning of the 20th century.New radiosonde instruments Shaving Bar for in situ humidity-, radiation- and gas-profile measurements in the troposphere and the lower stratosphere, were introduced in recent years for atmospheric research and climate monitoring, but such inst
