Public transportation is an important system of urban passenger transport. The purpose of this article is to explore the impact of network resilience when each station of urban rail transit network was attacked by large passenger flow. Based on the capacity load model, we propose a load redistribution mechanism to simulate the passenger flow propagation after being attacked by large passenger flow. Then, taking Xi'an's rail network as an example, we study the resilience variety of the network after a node is attacked by large passenger flow. Through some attack experiments, the feasibility of the model for studying the resilience of the rail transit system is finally verified.

Source code security audit is an effective technique to deal with security vulnerabilities and software bugs. As one kind of white-box testing approaches, it can effectively help developers eliminate defects in the code. However, it suffers from performance issues. In this paper, we propose an incremental checking mechanism which enables fast source code security audits. And we conduct comprehensive experiments to verify the effectiveness of our approach.
