Identity Crisis
For years, engineers have established the authenticity of original documents with stamps and signatures. Although stamps and signatures work well for hard copies of documents, they inadequate...
All Decked Out
After 50 years of wear, the deck of New York City's Williamsburg Bridge was buckling and badly in need of replacement. In 1994, consultants recommended replacing the deck...
Sim City of Angels
Using advanced computing techniques, UCLA researchers are developing a virtual model of the entire 4,000 sp mi Los Angeles basin. Accurate to the level of graffiti on the walls and store...
Defusing the Millennium Bomb
On January 1, 2000, some date-sensitive computer systems may interpret the year as 1900, wiping out or altering data or crashing altogether. Richard L. Bland was put in charge of assessing...
Freeway to the Future
A new network model is emerging introducing a new step between servers and desktops: middleware servers with querying software. The new network architecture, combined with the use of both...
Riding the Technology Wave
Computer hardware and software is getting faster, more powerful and more affordable. At the same time, the way in which engineers use the equipment is varying. Identifying costs and benefits...
