In power systems, distance relays detect and protects the system related from the faults in transmission lines. Distance relaying applies the principle of ratio comparison between the voltage and current which it equates to the impedance to detect faults. At times, the impedance may change i.e. either high (due to fault resistance) or low (due to load encroachment). It is mandatory for a distance...
While SOA promises great benefits in productivity and flexibility, the tools for securing these systems continue to lag behind. The ideal of SOA security is to provide trusted containers and frameworks that enforce policies established during deployment, and remove security logic and policy from application code completely. Standards such as WS-Security address some of the issues, but enterprise systems...
Data security is a major issue in any Web-based application. There have been approaches to handle intruders in any system, however, these approaches are not fully trustable; evidently data is not totally protected. Real world databases have information that needs to be securely stored. The approach of generating negative database could help solve such problem. A negative database can be defined as...
The ADSA (Adaptive Distributed Search and Advertising) project has advocated the use of a distributed search architecture that allows for many search engines to be independently owned and controlled, offering many advantages over the common centralised search architectures of today. Moreover, ADSA has introduced the facility for generating revenue from providing a search service. A number of quantitative...
