This paper presents a sliding mode control (SMC) strategy for a class of fractional-order nonlinear systems (FONSs) with unknown external disturbances and input uncertainties. A fractional-order integral sliding surface is introduced, and then, an ad

This paper proposes a novel image encryption algorithm based on an integer form of chaotic mapping and 2-order bit compass diffusion technique. Chaotic mapping has been widely used in image encryption. If the floating-point number generated by chaoti
