Vertical mill is an important equipment existing in cement industry. In the normal operation process, defect may easily occurs at some components due to the severe working environment. Taking the bearing component as an example, this paper proposed a novel fault diagnosis method based on entropy feature to discriminate the ball fault, outer race fault and inner race fault. This algorithm consists...
In order to distinguish true ship wakes from other spurious linear feature effectively, a novel method of ship wakes detection based on the Radon transform (RT) and on the entropy, and named joint Radon and entropy detection algorithm (JRE) is proposed. The proposed approach extracts all possible peaks in Radon transform space with a low threshold, then computes the entropies centering around each...
