The work in this thesis is based on continued fraction theory. Combining continued fractions with polynomial functions, we construct a new osculatory continued fraction interpolation—osculatory rational Hermite-like interpolation. Its representation is simpler than that of Hermite polynomial interpolation and its computation is concise since the continued fractions coefficients can be worked out by using Viscovatov algorithm.

Then, the minutiae sets are aligned globally through coordinate transform, and the alignment parameters are optimized by using affine transform and least square method. Finally, minutiae matching and directional field matching are respectively achieved based on the minutiae alignment, and the two matching scores are fused into a single to obtain a more reasonable result. Experimental results show that this method contributes to ensure the accuracy of fingerprint identification as well as possesses the real-time performance.

该算法首先利用脊线信息快速确定满足局部匹配要求的细节点对，在此基础上进一步通过全局坐标变换完成细节点的全局配准，并采用仿射变换模型通过最小二乘估计对配准参数进行优化，然后在配准的基础上分别进行细节点匹配和方向场匹配，最后对两种匹配分值进行融合，以取得较合理的匹配结果。

There are three important structural features in complex networks: small-world effect, scale- free property and network's navigability. Typical models reflecting these features, respectively, are the Watts-Strogatz's model, the Barabási-Albert's model and the Kleinberg's model. Based on the typical models, a new model of growing and navigable networks is proposed, with the generated networks possessing all these features simultaneously. The results of navigation obtained by using a greedy algorithm on networks of the model are similar to, or even better than, that of the Kleinberg's model.

复杂网络具有3种重要的结构特性：小世界性、Scale-free性和可导航性，反映它们的经典模型是：Watts-Strogatz模型、Barabási-Alhert模型和Kleinberg模型为了全面地反映出这些特性，在经典网络模型的基础上提出了一个新的增长可导航网络模型，这个模型同时具有这3种重要特征，并且在这个网络模型上使用贪婪算法时，它与Kleinberg模型具有相同的导航效果，有时甚至更加优越。
