Researchers from Oxford University’s Computing Laboratory have developed techniques to spot malicious attacks on computer networks, that include the use of Inductive Logic Programming (ILP) techniques to automatically determine the semantics of novel attack strategies.

Intrusions often take place where there are vulnerabilities within computer systems. For example, one of the most common of these is the buffer overflow, where an attacker sends overly long transactions to a server. The aim i

Pairing a real dancer with an animated dance partner is nothing new – it’s a technique used in any number of movies or television shows. But collaborating artists and engineers at the University of Illinois at Urbana-Champaign are putting a new spin on the idea.

Working with engineers in the Beckman Institute for Advanced Science and Technology at Illinois, visiting Beckman scholar Yu Hasegawa-Johnson is the visionary behind a real-time, high-tech pas de deux by dancers located thousands of

Penn State engineers have developed an economical way to more efficiently manage radio spectrum use and prevent interference on wireless broadband systems for high-speed Internet access – potentially bringing down costs for consumers. Dr. Mohsen Kavehrad, director of Penn State’s Center for Information and Communications Technology Research (CICTR), says, “With this technique, service providers could offer quality service to more homes using only a limited span of the radio spectrum. And, if pro

Following the research line of other initiatives at European and international level, the basque company VICOMTech and Fraunhofer IGD are working together in the development of a VITAL compliant platform for representation, storage and communication of vital signs. The platform will be flexible enough to be used in multiple platforms (PDA, PC, etc.), following the manager-agent architecture of the standard, with an open representation schema and extension possibilities. As a proof of the validity of

Whoever thinks that ants are only erratic little beings, whose incessant wanderings are pointless or obey no kind of universal order, is very much mistaken. Their society is so organized and complex that it is already being used as a model for the creation of algorithms, adaptable to a variety of scientific areas.

Inspired by the work of Chialvo and Millonas – the creators of the first numeric simulation according to which the formation of collective cognitive maps of social insects can be

Researchers at Ohio State University and their colleagues have expanded the possibilities for a new kind of electronics, known as spintronics.

Though spintronics technology has yet to be fully developed, it could result in computers that store more data in less space, process data faster, and consume less power. It could even lead to computers that “boot up” instantly, said Arthur J. Epstein, professor of physics and chemistry and director of Ohio State’s Center for Materials Research.
