aeroponic is a new technology for potato minituber production. in order to recognition of the suitable nutrient solution and potato variety for minituber production in aeroponics in comparison with classic hydroponics, a factorial experiment was carried out with three factors of culture systems (aeroponics and hydroponics), nutrient solutions (chang et al., 2008; apcoab and commercial nutrient ...

In most materials, there exists a coupling effect between heat and moisture during their transient diffusion. In particular, the coupling effect gives a significant change in the distributions of temperature and moisture concentration in some porous materials and resin composites (Chang, et al., 1991). Moreover, it is known that the absorption of moisture by hygroscopic materials under high-tem...

-Steganography is a skill to convey the secret data in the digital images without getting any unexpected notices to attackers. LSB replacement, the simplest method, directly replaces the secret bits with LSB bit plane. Unfortunately, it is insecure because it cannot resist against the visual attacks and statistic detection. The original work was proposed by Chang et al. in 2010, and their work ...

In ScaNaLU 2002, Chang et al presented a scalable natural language formalism called Embodied Construction Grammar (ECG) (Chang et al., 2002). ECG makes deep understanding systems possible because it is a rigorous, unified formalism that incorporates the semantic and pragmatic insights found in cognitive linguistics. The work described in this paper builds on (Chang et al., 2002) because it leve...
