When different mixing ratios of ethanol: water (ethanol: water = 25:75, 50:50, 75:25, and 100:0 by volume) flow through the GFs, their...
The effect of substrate temperature on chemical reactions during GaN growth in a vertical MOCVD
Lansheng Feng, Runqiu Guo, Jincheng Zhang
A model on GaN growth in a vertical MOCVD system is presented. Simulations on the GaN growth using the model are carried out under different substrate temperatures. The result shows that during the gas phase translation of the reactants, the adduct reactions decreased and the pyrolytic reactions are...
Non-local means image denoising with bilateral structure tensor
Huan Li, Yi Xu
Non-local means image denoising with bilateral structure tensor algorithm is put forward for the reason that Non-local means(NLM) algorithm has a weaker detail retention and noise immunity. Different from the initial structure tensor, we can get better texture description between similar blocks by using...
