AHP (analytic hierarchy process) has been widely used in decision making. Inner dependence method AHP is one technique even in case of criteria have dependency. However using original AHP or Inner dependence method, the results often lose reliability because the comparison matrix does not always have sufficient consistency. In these cases, fuzzy representation for weighting criteria and alternatives...
Digital watermarking techniques have been used for preventing an illegal copying and re-distributing of contents. A collusion attack is a strong attack against digital watermarking schemes. To prevent such attacks, a collusion secure fingerprint code can be used. Collusion secure fingerprint code have been studied widely and many codes have been proposed. However, a code length of them are too long...
In this paper, several investigations have been performed for solving the open problem that if small quaternion orthogonal design can be used to build larger one. The so called coordinate interleaved orthogonal designs (CIODs) are generalized into quaternion in the paper, and consequently it introduces a new construction technique for 4 n times 4 m rectangular matrices whose elements are quaternion...
The aim of "blind source separation" is to recover mutually independent unknown source signals from observations obtained through an unknown linear mixture system. Simultaneous diagonalization of correlation matrices (second-order statistics) of observations is one of the resolutions, when the unknown source signals are non-stationary. Although it is trivial that the true separation matrix...
