This paper presents an automated visual inspection scheme for multicrystalline solar wafers using the mean-shift technique. The surface quality of a solar wafer critically determines the conversion efficiency of the solar cell. A multicrystalline solar wafer contains random grain structures and results in a heterogeneous texture in the sensed image, which(More)
Article history: Received: 23.10.2013. Received in revised form: 25.03.2014. Accepted: 26.03.2014. This paper considers a multi-degree-of-freedom mechanical system with local cubic nonlinearities. A major concern is placed on nonlinear dynamic behaviors of the system subjected to a soft harmonic excitation under primary resonance condition. The classical(More)
