Python is widely used to create and manage complex, database-driven websites. However, due to dynamic features such as dynamic typing of variables, Python programs pose a serious security risk to web applications.

Currently, the main threats of network security are coming from hacker intrusion, deny of service (DoS), computer virus, worm, spam, malicious code and sniffer because there are many weaknesses in the original design of IPv4. One is that attackers could send IP spoofing packets which is he wants to attack. That is the attackers modify the IP from the true one to another on the IP field. However, it...
The composite steel frame-reinforced concrete infill wall structure is considered as a new type of earthquake-resistant system with brilliant future of application. In order to study the hysteretic behavior of the structure, a large scale specimen under cyclic load was conducted and then the computer simulation models were established using the software ANSYS. By comparison, the computer calculated...
