With Monte Carlo simulations, we study the dynamic relaxation at perfect and imperfect surfaces of the three-dimensional Ising model with an ordered initial state. The time evolution of the surface magnetization, the line magnetization of the defect line, and the corresponding susceptibilities and second cumulants is carefully examined. Universal dynamic scaling forms including a dynamic crosso...

This article proposes a lightweight YOLO-ACG detection algorithm that balances accuracy and speed, which improves on the classification errors missed detections present in existing steel plate defect algorithms. To highlight key elements of desired area surface flaws plates, void space convolutional pyramid pooling model is applied to backbone network. fusion high- low-level semantic informatio...

Green plums are a characteristic fruit resource in China, with long history of cultivation. Many surface defects will appear the growth, transportation and preservation green which seriously affect processing quality by-products. The existing manual sorting method is limited by experience workers. It difficult to ensure speed detection. Therefore, formation automatic detection great significanc...
