Considering the nonlinear bistable vibrational resonance(VR) system, the mean signal-noise-ratio gain(MSNRI) is taken as performance index and VR phenomenon subjected to the action of high and low frequency signals is studied under α stable noise. Then the action laws between the amplitude B and frequency Ω of a high frequency drive signal on the resonant output effect is explored. Finally, the multi-high...
The Melting process is one of the main processes in the Czochralski method. Detecting the melting process is important for entire automation of the CZ crystal furnace. In regards to the furnace melting process, this paper presents a kind of image-based method to detect the size of the silicon ingot at later stages of the process. It could achieve the purpose of optimizing the heating power and process...
