Any backup to the Big Board's current trading floor should be a physical site, not a computer simulation, said Andrew Cader, a managing director at Goldman who is co-chief executive of Spear, Leeds.
The team has carried out both field tests and computer simulations, and says "engineering issues" remain.
Computer simulations, he says, have shown that the essential mechanism--magnetic resonance--means little or no power is transferred to extraneous objects, such as computer hard drives or even magnetic stripes on credit cards.
Here's why we can believe what these kinds of computer simulations tell us.
The computer simulations, Dr. Hogan said, reveal that "the web itself makes great cinema".
Then, in computer simulations, Dr. Kane said, the results showed that the velocities and densities of matter in the columns in fact conformed to the Rayleigh-Taylor principle.
According to gravity theory and computer simulations, she said, dark matter, which only interacts gravitationally, should start out in rounded lumps and then gradually shape itself into filaments and sheets as these lumps collapse along their shortest axes first.
Astrophysicists at the Lawrence Livermore National Laboratory here have tested some of the ideas with computer simulations and say they think they understand the natural forces that may have created such dazzling cosmic architecture.
Using computer simulations, Gray said he was able to "draw a clear map tracing the trail of health damages left by the coal fumes released by every power plant in China, untangling the contribution of individual companies, provinces and power stations to the air pollution crisis gripping the country".
