Railway interlocking system is a safety critical system. Its malfunction can cause the loss of human life and severe injuries. To remove difficulties from this type of system better and advanced methodologies are required. This paper presents the use of Z-specification to specify the safety properties of the train system. The paper provides division of railway track into sectors and further division...
Distributed denial of service (DDoS) attacks have become a major threat to organizations and especially to Internet and intranet. In DDoS attacks targets are overwhelmed by sending an enormous amount of traffic from a number of attack sites. The major tasks of any defense system are to detect these attacks accurately and early on, before it causes an unrecoverable loss. Most of the research in this...

It is not surprising that the process of change detection is fundamental to many machine vision applications. Most change detection algorithms assume that the illumination on a scene will remain constant. Unfortunately, this assumption is not necessarily valid outside a well-controlled laboratory setting. The accuracy of existing algorithms decreases significantly when faced up with image sequences...
