Moreover, the synchronization of EAN is studied; the result shows that the stochastic networks are more poorly synchronized than their deterministic counterparts. These models can well mimic some real systems. Firstly, two dimensional random Apollonian networks and two dimensional EAN are maximal planar graphs, which may be helpful for designing printed circuits. Secondly, V-HDRAN can be mapped into the Yule process, which was inspired by observations of the statistics of biological taxa. From this perspective, V-HDRAN can find some applications in biological systems. Thirdly, all networks of this type consist of complete graphs; this particularity of the composing units can provide a comprehensive aspect to understand some real-life systems making up of complete graphs, such as movie actor collaboration networks, scientific collaboration networks and networks of company directors.

这些模型可以很好地描述现实系统,其中二维随机阿波罗网络与二维演化的阿波罗网络为最大平面图,这对印刷电路板等现实系统的设计有重要的借鉴作用;变体模型V-HDRAN的构建过程与Nature上发表的关于生物物种的形成过程之间存在一个一一对应的关系,这对生物系统的建模有重要的价值;另外,这类网络均由完全图组成,它们对由完全图组成的电影演员合作网、科学家合作网、公司董事网等由完全图构成的现实网络的建模有重要的理论意义和应用价值。

Results 3 cases of lesions were in the gap of"V"shape between iliac muscle and musculus psoas major on the coronal sections in the lower right abdomen closely adjacent to the cecum,which were narrowed. The lesions showed long even T1 and T2 signals similar to mucous wall particularly in T2WI image. The walls of cyst were thin and even. The cysts were round or oval in shape on transections.The cyst were cucurbits in shape in 2 cases and long cannular in a case on coronal sections and arrowy sections and borderlines of the cysts were clear. The terminal of the cysts showed taper in 2 cases. In addition, cecum polypus was found at the placket of the appendix in a case which was not shown on MRI image.

Applying LMI technique, quadratic stability theory, and H〓 control theory, three methods of robust stability analysis and robust controller design for uncertain fuzzy systems are proposed respectively. Among them, LMI based technique can analyze the uncertainties raised in the premises and in the consequent of fuzzy systems. The resulting stabilizing state feedback controllers have maximum stability margins for both kinds of uncertainties. Quadratic stability theory based approach can apply LMI technique and other methods to design fuzzy controllers. H〓 control theory based design can get H〓 controller with constant disturbance attenuation for each local subsystem. Using the given stability criterion of generalized systems, the robust stability of fuzzy systems can be checked.

其中,基于LMI的方法可分析由模糊系统的前件或后件引起的不确定性,得到的稳定的状态反馈控制器对这两类不确定性具有最大的稳定裕度;基于二次稳定理论的方法可应用LMI技术和其它方法设计模糊控制器;基于H〓控制理论的方法可得到各局部子系统具一定干扰抑制性能的鲁棒H〓控制器,而全局系统的鲁棒稳定性可应用所给出的稳定条件进行检验。
