摘要

这项研究有两个目的。首先，利用非周期性间歇控制技术探讨了带有时间延迟的分数阶神经网络的主从同步问题。然后，我们提出了通过平均宽度间歇控制技术实现延迟分数阶神经网络主从同步的充分条件。通过数值模拟证明了推导结果的有效性。其次，对 Hermite 分形样条曲线的 Caputo 分形导数进行了新颖的研究。此外，我们还估算了其盒计维度，并将其与卡普托分形阶数联系起来。此外，我们还提出了一种利用半张量积（STP）的图像加密算法。该算法的效率通过应用统计量进行了评估。

Fractional derivative of Hermite fractal splines on the fractional-order delayed neural networks synchronization

The purpose of this research is twofold. First, the master–slave synchronization of fractional-order neural networks is explored with time delays using aperiodic intermittent control. Then we present a sufficient condition for master–slave synchronization of delayed fractional-order neural networks via average-width intermittent control technique. A numerical simulation is used to demonstrate the efficacy of the derived results. Second, a novel investigation of the Caputo-fractional derivative of Hermite fractal splines is accomplished. Moreover, its box counting dimension is estimated and related with the Caputo-fractional order. Additionally, we propose an image encryption algorithm utilizing the semi-tensor product (STP). The efficiency of the algorithm is evaluated through the application of statistical measures.
