This paper studies the convergence problem of progressive Gaussian approximation filters (PGAFs). The convergence analysis of the PGAF is presented based on the Lyapunov method. It is proved that the estimation error is bounded when the convergence conditions hold. Based on the convergence...

The influence of pre-stretching prior to artificial ageing on microstructure, tensile properties, and fatigue behavior of AA2099-T8 plates were investigated. The results showed that increased pre-strain level from 1% to 6% resulted in more uniform distribution and increasing density of the T1...
