Analysis of Identification Methods of Key Nodes in Transportation Network

The identification of key nodes plays an important role in improving the robustness of the transportation network. For different types of transportation networks, the effect of the same identification method may be different. It is of practical significance to study the key nodes identification methods corresponding to various types of transportation networks. Based on the knowledge of complex networks, the metro networks and the bus networks are selected as the objects, and the key nodes are identified by the node degree identification method, the neighbor node degree identification method, the weighted k-shell degree neighborhood identification method (KSD), the degree k-shell identification method (DKS), and the degree k-shell neighborhood identification method (DKSN). Take the network efficiency and the largest connected subgraph as the effective indicators. The results show that the KSD identification method that comprehensively considers the elements has the best recognition effect and has certain practical significance.

Constructing Kanchi

This book traces the emergence of the South Indian city of Kanchi as a major royal capital and multireligious pilgrimage destination during the era of the Pallava and Chola dynasties (ca. seventh through thirteenth centuries). It presents the first-ever comprehensive picture of historical Kanchi, locating the city and its more than 100 spectacular Hindu temples at the heart of commercial and artistic exchange that spanned India, Southeast Asia, and China. The author demonstrates that Kanchi was structured with a hidden urban plan, which determined the placement and orientation of temples around a central thoroughfare that was also a burgeoning pilgrimage route. Moving outwards from the city, she shows how the transportation networks, river systems, residential enclaves, and agrarian estates all contributed to the vibrancy of Kanchi's temple life. The construction and ongoing renovation of temples in and around the city, she concludes, has enabled Kanchi to thrive continuously from at least the eighth century, through the colonial period, and up until the present.
