New "tapping" sensor could help in fight against fraud

The way a person taps a number into a cash machine or mobile phone, could, according to scientists at the University of Southampton, be used as a means of identification, and prove useful in the battle against fraud.

Professor Neil White of the University of Southampton’s Department of Electronics and Computer Science has developed an inexpensive sensor, which can be integrated into objects of various shapes and sizes, including smart cards and hand-held devices such as mobile phones.

Buzzwords of history, revealed by computer scans, indicate new ways of searching the Web

In the years after the American Revolution, U.S. presidents were talking about the British a lot, and then about militias, France and Spain. In the mid-19th century, words like “emancipation,” “slaves” and “rebellion” popped up in their speeches. In the early 20th century, presidents started using a lot of business-expansion words, soon to be replaced by “depression.”

A couple of decades later they spoke of atoms and communism. By the 1990s, buzzwords prevailed.

Falling prey to machines

Can sentient machines evolve?

It’s coming, but when? From Garry Kasparov to Michael Crichton, both fact and fiction are converging on a showdown between man and machine. But what does a leading artificial intelligence expert–the world’s first computer science PhD–think about the future of machine intelligence? Will computers ever gain consciousness and take over the world?

“Computer sentience is possible,” said John Holland, professor of electrical engineering an

Sapphire/Slammer worm shatters previous speed records for spreading through the Internet

A team of network security experts in California has determined that the computer worm that attacked and hobbled the global Internet eleven days ago was the fastest computer worm ever recorded. In a technical paper released today, the experts report that the speed and nature of the Sapphire worm (also called Slammer) represent significant and worrisome milestones in the evolution of computer worms.

Ultra-high-density data storage may become practical with breakthrough in nanoscale magnetic sensors

A simpler and more reliable manufacturing method has allowed two materials researchers to produce nanoscale magnetic sensors that could increase the storage capacity of hard disk drives by a factor of a thousand. Building on results reported last summer, the new sensors are up to 100 times more sensitive than any current alternative technology.

Project seeks to balance power, performance in embedded computers

“The computing world is moving from the desktop and workstation to an arena of embedded and wearable computers,” remarked Sandeep Shukla, who recently received a $400,000 grant from the National Science Foundation to help solve one of the major problems in this transition.

Shukla, who joined the Virginia Tech electrical and computer engineering faculty in August 2002, will use his Faculty Early Career Development Program (CAREER) Award to devise a strategy for achieving the optimal balance
