He created a computer-based simulation of patients in need of diagnosis, called Immex.

FORBES: Instant feedback in the classroom

Since 1992, in the place of testing, the United States has relied for "stockpile stewardship" on a host of computer-modeling, other simulation techniques and non-nuclear explosive tests that have provided insights into the performance of an aging arsenal.

CENTERFORSECURITYPOLICY: Are we serious about deterrence?

Rather than discussing the already worn (and to me irrelevant) debate of digital book versus analog book, I talked about future technologies like brain computer interface, real-time simulation and programmable material, and how these will change the face of literature far beyond the Kindle, perhaps eventually eliminating text altogether.

But in an agent-based model you simply run a computer simulation to see what emerges, free from any top-down assumptions.

ECONOMIST: Economics focus

The computer simulation showing the time-stamp effect in the study is novel and original, said Joe Manns, assistant professor of psychology at Emory University in Atlanta, Georgia.

Then they re-created these turbulent events using a computer simulation that models the atmosphere.

Now, Markram is announcing a collaboration with IBM (nyse: IBM - news - people ) to create a computer simulation of these fundamental neurological units, called neocortical columns.

Considering that, a few years ago, it was rare to get the computer time needed to do even a single geoengineering simulation with a state-of-the-art climate model, this investment of time and effort marks a big step forward.

ECONOMIST: Geoengineering

Now a new computer simulation confirms what some long suspected: The H5N1 virus already has spread from human to human--or at least it did in one case cluster last year in Indonesia.
