针对一类周期性时变非线性系统，提出了一种部分周期的自适应重复控制方法。 为了减少内存使用量，探索了周期性参数的对称特征，以形成部分周期自适应机制。 提出了半周期和四分之一周期的适应策略，并对它们进行了分析。 建立了具有每个重复控制的闭环系统的稳定性，以及跟踪误差收敛到零。 另外，建议使用饱和适配来提供有界估计。

将能够增强图像纹理信息的分数阶微分算子与变分偏微分方程相结合，运用于图像去噪，提出一种基于分数阶偏微分算子的去噪模型。该模型能够在抑制噪声的同时，更好地保持图像的纹理细节信息。由于分数阶微分算子的阶数必须通过大量的实验人为确定，因此选择通过计算局部方差来反应图像局部纹理复杂度，自适应地确定分数阶微分的阶数。实验表明：自适应分数阶偏微分算子不仅继承了TV模型的优点，并且在保持图像细节信息上的能力更强。

Traditional routing schemes, such as OSPF, optimize data plane routing e±ciency by maintaining full view of the network at the control plane. However, maintaining full network view and handling frequent routing information updates are costly in large-scale complex networks, which are considered to be the root causes for the routing scalability issue. Recently, it is suggested that routing on local or partial information is plausible if slight performance degradatio

"This important volume is the first part of a two-part textbook (the second part is entitled Conservation laws and elliptic equations). The text includes interesting homework problems that implement different aspects of most of the schemes discussed. The implementation aspect of this text includes a large amount of computing. Other useful aspects of computing included in this volume are symbolic computing and the use of graphics for analysis. Prerequisites suggested for using this book might include one semester of partial differential equations and some programming capability. This book will be a good reference text for students." -- MATHEMATICAL REVIEWS
