In this paper, we propose the defect detection algorithm using the image processing in cold rolling. This algorithm consists of two separated parts: defect detection of the steel sheet in a rolling process and defect detection of the cutting plane in a side trimming process. The objective of the crack and hole detection is to find the position and diameter(More)
Cognitive Radio is promising technology to improve spectrum utilization. Routing in Cognitive Radio Networks (CRNs) is important because of efficient communication on the wireless multi-hop environment. In this paper, we present a reducing routing overhead method on CRNs. Simulation result show that, our proposed scheme achieves less routing overhead than(More)
