Abstract: This study tries to reach an approach for hemorrhage control process based on using Nd:YAG laser, in order to reduce the time needed for coagulation. The Nd:YAG laser with its different powers and modes is one of the most widely used lasers in medical applications . The research shows that this laser type is a powerful and useful method for haemostaisis, one of the most important medical applications of laser with no mentioned side effects. The work in this study describes the improvement of haemostaisis time by using Nd:YAG laser.

Abstract: The data security can be enhanced by using IPSec/VPN policies. In this work the task of encryption are integrated to provide the higher level of security services. The work has focused on the tunnel technique to be the core of the proposed VPN. A tunnel is a way to transfer data that can be enclosed by the corresponding tunnel protocol (IPSec tunnel mode). Raw socket software programming interface has been implemented to send and receive IP datagrams throughput the network.
