Abstract: A system and a method for handling laser-communication multiplexing in chaotic secure communications are disclosed. The messages to be multiplexed are encoded by chaotic laser signals of a transmitter system. The transmitted signals are then coupled to another chaotic system, the receiver system, so that the receiver and the transmitter are asymptotically synchronized. The decoding of the multiplexed messages encoded by chaotic behaviors is achieved by using a low-pass filter. This low-pass filter can effectively increase the fractal dimension of the chaotic system and enhance the periodicity of the transmitted time sequences, so that the multiplexed messages can be recovered.

Abstract: Disclosed herein is an ink composition for ink-jet textile printing, which primarily includes (a) at least a reactive dye, (b) water, and (c) at least an organic solvent that is a C4-C6 polyhydric alcohol having one or less primary alcohol groups. The ink composition of the present invention is suitable for dyeing and printing of materials containing either cellulose fibers such as cotton, synthetic cotton, hemp, and synthetic hemp, or amide fibers such as wool and nylon.
