The purpose of digital image scrambling technology is to put a meaningful into disordered one enhance the resistance ability against illegal attacks. This paper proposed an algorithm based on idea movement elephant in chess board system consist two main steps first rotate each diagonal by key generated from computing standard deviation second step include exchange upper half with lower shows go...

A method of optimal intermediate voltage tracking (OIVT) is proposed in this paper to improve efficiency for the cascade boost converter. The can be adjusted by regulating duty cycle front stage and rear converters. To control speed algorithm, range determined calculating overall system loss. In addition, with input-output relationship maintained, root-mean-square (rms) current capacitor reduce...
