Jin, Zujin (author), Cheng, Gang (author), Pang, Y. (author), Xu, Shichang (author), Yuan, Dunpeng (author)During the processing of an optical mirror, the performance parameters of the bottom support system would affect the surface forming accuracy of the mirror. The traditional bottom support system has a large unadjustable support stiffness, which increases the difficulty of unloading the impact force generated by the grinding disc. In response to...journal article 2021

Li, X. (author), Cheng, Ai Jie (author), Lin, H.X. (author)We present an approach which combines the sample regenerating particle filter (SRGPF) and unequal weight ensemble Kalman filter (UwEnKF) to obtain a more accurate forecast for nonlinear dynamic systems. Ensemble Kalman filter assumes that the model errors and observation errors are Gaussian distributed. Particle filter has demonstrated its...journal article 2021

Li, Wenting (author), Cheng, Haibo (author), Wang, Ping (author), Liang, K. (author)Multi-factor authentication (MFA) has been widely used to safeguard high-value assets. Unlike single-factor authentication (e.g., password-only login), t-factor authentication (tFA) requires a user always to carry and present t specified factors so as to strengthen the security of login. Nevertheless, this may restrict user experience in...journal article 2021
