’Hot laps’ to become yesterday’s problem

Laptops make laps hot, as users of mobile lightweight computers sometimes learn dramatically. (If you’re not easily shocked, go to http://www.reuters.com). And things could get worse: upcoming chips may produce 100 watts per square centimeter — the heat generated by a light bulb — creating the effect of an unpleasantly localized dry sauna. (Current chip emanations are in the 50 watts/cm2 range.)

New software that responds to written questions by retrieving digital images has potentially broad application, ranging from helping radiologists compare mammograms to streamlining museum curators’ archiving of artwork, say the Penn State researchers who developed the technology.

Dr. James Z. Wang, assistant professor in Penn State’s School of Information Sciences and Technology and principal investigator, says the Automatic Linguistic Indexing of Pictures (ALIP) system first build

Researchers at the University of Leeds have rescued the BBC Domesday Project, preserving it for future generations. The CAMiLEON Project has developed software that emulates the obsolete BBC computer and videodisc player on which the original system ran.

The BBC Domesday project was conceived by the BBC to celebrate the 900th anniversary of the 1086 Domesday book. It formed a social snapshot of life in the UK during the mid eighties. Information was recorded on two virtually indestructible i

The World Wide Web Consortium (W3C), the National Institute for Research in Computer Science and Control (INRIA) and the European Research Consortium for Informatics and Mathematics (ERCIM) jointly announced organizational changes which aim to strengthen research relationships throughout Europe to better support Web technology development.
The change of W3C European Host from INRIA to ERCIM will take place on 1 January 2003. The change allows W3C to better leverage research relationships througho

Ancient artists used a technique called stippling – in which pictures are created by painting or carving a series of tiny dots – to produce drawings on cave walls and utensils thousands of years ago.

Now engineers at Purdue University have created a new kind of computer-imaging software that uses stippling to quickly produce complex pictures of internal organs and other renderings. The method is 10 times faster than some conventional methods and could provide a tool for medical professionals
