In a paper by Chang [D.Y. Chang, Applications of the extent analysis method on fuzzy AHP, European Journal of Operational Research 95 (1996) 649–655], an extent analysis method on fuzzy AHP was proposed to obtain a crisp priority vector from a triangular fuzzy comparison matrix. It is found that the extent analysis method cannot estimate the true weights from a fuzzy comparison matrix and has l...

The purpose of the current study was to generalize the use of the a-stratified method with b blocking (Chang, Qian, & Ying, 2001; denoted STR_B) to computerized adaptive testing (CAT) with the generalized partial credit model (Muraki, 1992). Chang et al. (2001) showed that STR_B performs well in reducing highly discriminating items' exposure rates and increasing lower a items' usage while maint...

In recent years, there are many reversible data hiding scheme proposed. Most schemes are guaranteed that the original cover image can be reconstructed completely. When the secret data are hidden in the compression image, the receiver need to extract the secret data, reconstruct the original cover image, and compress the image to save the space. In 2006, Chang et al. [5] proposed a reversible da...
