Improving the dynamic security and stability of a shipboard power system was studied by distributing energy storage elements. The notional ship power system under study has an AC network consisting of four alternators (two main and two auxiliary turbine generators), a DC microgrid involving distributed renewable energy generation and hybrid battery/super capacitor (SC) energy storage system. In...

-In this present era, system and network technology is considered as a key tool for a wide variety of applications. Network security affects many organizations, and it becomes one of the major tasks. Biometric is one of the most secure and suitable authentication tools. By using biometrics in a correct way, many problems can be solved by using user identification and passwords.

Wireless LANs are open and are vulnerable to various attacks. Techniques available to prevent Wireless LANs from these attacks are not comprehensive. In this paper we discuss the drawbacks of the existing security mechanisms and we provide a security architecture which uses Mobile agents as a security facilitator. Using this architecture, users have freedom to choose from a variety of encryptio...
