With the rapid development of China’s printed circuit board industry, bare-board defect detection has high research and application values as an important factor in improving production quality. In this paper, a new method based on YOLOv5 is proposed to solve balance problem efficiency performance task detection. First, k </math...

The hierarchical structure of the data center network is more and unsuitable for increasing east-west traffic from virtual machines. Reconfigurable circuit switching utilized to reduce regional hotspots, which causes problem routing oscillation. We propose a stratospheric center, combines Tor switches. It acts as supplement tropospheric transmission across alleviate global hotspots. link VCS (V...

We propose a post-placement physical synthesis algorithm that can apply multiple circuit synthesis and placement transforms on a placed circuit to improve the critical path delay under area constraints by simultaneously considering the benefits and costs of all transforms (as opposed to considering them sequentially after applying each transform). The circuit transforms we employ include, but a...
