We present the Generalized Root Mean Square Deviation (G-RMSD) method. G-RMSD is an optimization method to calculate minimal RMSD value of two atomic structures by optimal superimposition. not restricted systems with equal number atoms compare or a unique atom mapping between molecules. The can handle any type chemical structure, including transition states and which cannot be explained only va...

Hotelling T 2 control chart not only reflects the correla-tions between different quality characteristics but also has good efficiency on monitoring multivariate in production process. A new alternative was constructed after original products data are processed by using exponentially weighted moving average for cumulating failure effects because is ineffective detecting minimal mean deviations....
