Image Compression and Encryption Based on Compressive Sensing and Game of Life With Semi-Tensor Product

Yiting Guo, Hao Zhang, Changhong Zou, Shuang Zhou et autres

This paper proposes an image compression and encryption algorithm based on 3D Logistic-Sine-Memristor coupled map (3D-LSMCM), compressed sensing (CS) and the Game of Life scrambling with Semi-Tensor Product (STP-GoL) to solve the problems of computational redundancy and security vulnerability in image transmission. …

Two ADI compact difference methods for variable-exponent diffusion wave equations

Hao Zhang, Kexin Li, Wenlin Qiu

In this work, we study two-dimensional diffusion-wave equations with variable exponent, modeling mechanical diffusive wave propagation in viscoelastic media with spatially varying properties. We first transform the diffusion-wave model into an equivalent form via the convolution method. Two time discretization strategies are …

Semi-tensor product based long-run behavior estimation of generalized asynchronous Boolean networks with time delays

Guowei Li, Chao Luo, Shuang Zhou, Lunshi Xu et autres

This paper investigates the long-run behavior estimation of generalized asynchronous Boolean networks with time delays, particularly the evolutionary trends of the attractor and its basin. First, the dynamic form of the original network is remapped into an equivalent augmented system based on …
