Li, Y. (author), Cheng, G. (author), Pang, Y. (author), Kuai, Moshen (author)Poor working environment leads to frequent failures of planetary gear trains. However, complex structure and variable transmission make the vibration signal strongly non-linear and non-stationary, which brings big problems to fault diagnosis. A method of planetary gear fault diagnosis via feature image extraction based on multi central...journal article 2018

He, D. (author), Pang, Y. (author), Lodewijks, G. (author), Liu, X. (author)Belt conveyors play an important role in the dry bulk material handling process. Speed control is a promising method of reducing the power consumption of belt conveyors. However, inappropriate transient operations might cause risks like material spillage away from the belt conveyor. The unexpected risks limit the applicability of speed...journal article 2018

Yan, Gaowei (author), Jia, Songda (author), Ding, Jie (author), Xu, Xinying (author), Pang, Y. (author)In this paper, a local cloud model similarity measurement (CMSM) is proposed as a novel method to measure the similarity of time series. Time series similarity measurement is an indispensable part for improving the efficiency and accuracy of prediction. The randomness and uncertainty of series data are critical problems in the processing of...journal article 2018

He, D. (author), Pang, Y. (author), Lodewijks, G. (author)Belt conveyors can be partially loaded due to the variation of bulk material flow loaded onto the conveyor. Speed control attempts to reduce the belt conveyor energy consumption and to enable the green operations of belt conveyors. Current research of speed control rarely takes the conveyor dynamics into account so that speed control lacks...journal article 2017

Pang, Cheng (author), Liu, Hong (author), Zhang, J. (author), Li, Xiaofei (author)Binaural sound source localization is an important technique for speech enhancement, video conferencing, and human-robot interaction, etc. However, in realistic scenarios, the reverberation and environmental noise would degrade the precision of sound direction estimation. Therefore, reliable sound localization is essential to practical...journal article 2017

Pang, X. (author), Fischer, D.G. (author), Visser, T.D. (author)We study the Gouy phase of a scalar wavefield that is focused by a lens suffering from primary spherical aberration. It is found that the Gouy phase has different behaviors at the two sides of the intensity maximum. This results in a systematic increase of the successive wavefront spacings around the diffraction focus. Since all lenses have some...journal article 2013
