A new security approach could improve safeguarding of credit card numbers, bank passwords and other sensitive information for those who surf the Internet using wireless connections, researchers told the annual meeting of the American Association for the Advancement of Science (AAAS)on Saturday.

The same protocol could be employed in many computer networks in which two computers, hand-held communication devices or network nodes need to simultaneously verify the identity of each o

If you’re a ship captain and there might be 50-foot waves headed your way, you’d appreciate some information about them, right? That’s the idea behind a wave model system a Texas A&M University at Galveston professor has developed. His detailed wave prediction system is currently in use in the Gulf of Mexico and the Gulf of Maine.

Vijay Panchang, head of the Department of Maritime Systems Engineering, doesn’t make waves – he predicts what they’ll do, when

“The Web will become more than what we see on our computer screens, it will become a place where computers interact with each other and where meaning is attached to information.” That is the vision behind a cutting-edge Semantic Web project.

For Richard Benjamins, the coordinator of the IST project ESPERONTO, the future of the Semantic Web lies in it becoming “something akin to ambient intelligence” with the meaning of digital information understandable not only by humans but by a

A new semantic web interface, which will improve access to information and present search results in associated categories in one window, was launched this week.

This new approach means that instead of users having to wade through long lists of search data to decide what is relevant, the interface will enable the machine to pull related sources into one usable view.

Sweden’s new supercomputer for weather forecasting will greatly improve prediction reliability. An enhanced and powerful computational package, tailored especially for the needs of the Swedish Meteorological and Hydrological Institute, SMHI, is now installed at the National Supercomputer Center, NSC, sited at Linköping University.

The new computer system, called Blixt in honor of its lightning-fast processing, employs new computational methods to forecast land and sea weather cond

A major difficulty in developing automated language translation is that you need a system with a fairly extensive vocabulary from which it can learn, before any degree of reliability or accuracy is possible. The LC-STAR project developed just such a vocabulary.

“First, we created large lexica for several language databases,” explains project coordinator Ute Ziegenhain of Siemens in Germany. “Secondly, we developed a demonstrator that could automatically translate speech to speec
