— Networked Control System (NCS) is a synthetic application wh ich co mbines control science, computer science and network technology. It is a kind of feedback control systems wherein the control loops are closed through real time control network. NCS technology is applied in industry control system because of its simple structure, easy maintenance and high(More)
This paper describes a method for noise removal from ultrasonic signals used in NDE (Non Destructive Evaluation) applications. The method used is FPGA based adaptive noise cancellation. Indeed adaptive filtering is one of the core technologies in digital signal processing. We can find numerous application areas in science as well as in industry. Adaptive(More)
The Mobile WiMAX IEEE 802.16e is a neoteric technology providing broadband data access to mobile and stationary users while supporting handover and roaming capabilities. In the area of security aspects, Mobile WiMAX exhibits vulnerabilities while adopting improved security architecture. Bandwidth is an additional overhead in reducing these vulnerabilities.(More)
Nowadays, video contents are stored in huge files or it is televised in continuous streams but the users need to retrieve only a particular part of topic or shots from video. So we need to split it in to short video segments with respect to appropriate retrieval units automatically and efficiently. In this research work, based on shot changes two different(More)
Address Resolution Protocol (ARP) is used to map the network address (IP address) to a physical address (MAC address). Being a stateless protocol and lacking proper authentication mechanism in the ARP messages, ARP is vulnerable for cache poisoning attack. Attacker can perform Man-In-The-Middle (MITM) attack or Denial of Service (DoS) attack and can access(More)
