Wavelet bootstrapping

For certain classes of data that may be very expensive or difficult to obtain, a new statistical technique may provide useful information from a single data run by allowing meaningful re-sampling.

The technique, known as “wavelet bootstrapping” or “wavestrapping,” has applications in the geophysical sciences, bioinformatics, medical imaging, nanotechnology and other areas. It can also be useful for rapidly obtaining information from small data sets in s

A snowboarder’s dream come true: THE HUB, a ’wearable electronics’ jacket wired for both sound and mobile telephony capable of withstanding the most radical snowboarding environment.

Designed by Infineon Technologies and O’Neill Europe (a leading high-quality sports wear and gear producer), THE HUB incorporates technology resulting from initial research done under the European Commission’s ESPRIT and IST research programmes.

“The success of wearable electr

E-commerce makes it possible for a customer to order a mix of books, CDs and videos which will be shipped within 48 hours. Increasing “B2C” (business-to-customer) e-commerce and other ordering methods requires a new mailing and packaging philosophy. The partners in EUREKA project E! 2550 MAILPACK have developed a new mail management and packaging system to meet this challenge.

“Currently such orders are fulfilled by hand, or semi-automatic systems,” explains Ad Linssen, Financial Manager at

NSF sensors activities in focus at AAAS annual meeting in Seattle

In the 1990s, the Internet connected us to a planet-wide web of information-all the zillions of bits that are stored in computer memories and hard drives. But now, thanks to an ongoing revolution in highly miniaturized, wirelessly networked sensors, the Internet is reaching out into the physical world, as well.

“We call it ’the Embedding of the Internet’,” says Deborah Estrin, who is a computer scien

Security mechanisms also must protect what goes out

Passwords to guard entry aren’t enough to protect complex data – security mechanisms also must protect what goes out

“Data can easily find itself in danger of being accessed by ’bad guys,’” says emeritus professor of computer science Gio Wiederhold, who will speak about trusted information databases Feb. 14 in Seattle at the annual meeting of the American Association for the Advancement of Science (AAAS). “Pa

Equipped with cutting-edge techniques to track the activity of tens of thousands of genes in a single experiment, biologists now face a new challenge – determining how to analyze this tidal wave of data. Stanford Associate Professor of Computer Science Daphne Koller and her colleagues have come to the rescue with a strategic approach that reduces the trial-and-error aspect of genetic sequence analysis.

’’What we’re developing is a suite of computational tools that take reams
