Extensible Markup Language (XML) is becoming the de facto standard for exchanging information over the Internet, which results in the proliferation of XML documents. This has led to increased interest in this area by the research community. One of the main challenges is processing large collections of XML documents efficiently.

Although results from factor-analytic studies of the broad, second-stratum abilities of human intelligence have been fairly consistent for decades, the list of broad abilities is far from complete, much less understood. We propose criteria by which the list of broad abilities could be amended and envision alternatives for how our understanding of the hot intelligences (abilities involving emoti...

on a hierarchical organization of the data management control function and makes use of list processing concepts. Discussed are the separation of the logical and physical control functions as well as the data-element and operating-system controls. This hierarchical approach establishes a common basis for the creation, maintenance, and retrieval of data in direct-access storage. Logical function...

Steganography is a science of hiding messages into multimedia documents. A message can be hidden in a document only if the content of a document has high redundancy. Although the embedded message changes the characteristics and nature of the document, it is required that these changes are difficult to be identified by an unsuspecting user.

Controlled Flight into Terrain is one of the major sources of accidents in aviation today. Studies have shown that the use of Terrain Awareness and Warning Systems (TAWS) can decrease the number of such accidents. A problem with current TAWS is that the majority of them use the same display window as other information such as weather, traffic, airport positions, and moving map programs. The amo...
