81.   In this age of computer simulation and instant global communication, some things must be done the old-fashioned way.

82.   In the absence of testing, computer simulations are one of the main ways of telling if nuclear weapons will work as designed.

83.   Indeed, computer simulations show that galaxies remain stable only if they are surrounded by spherical halos of considerable unseen material.

84.   Information from these tests and the fluid dynamics programs then go into a larger computer simulation called a velocity prediction program, or VPP.

85.   It is true that computer simulations and complexity theory have made it possible to visualize processes and transformations that were once invisible or difficult to explain.

86.   Just how these fringes reduce noise was unclear, so Lilley used computer simulations to work out what they did.

87.   Leslie Abramson, the defense attorney representing Erik Menendez, essentially accused the witness presenting the computer simulation last week of incompetence and fabricating evidence.

88.   Lockheed Martin has used computer simulation to improve its JSF entry and to save money in production.

89.   Martinez said his agency would conduct four front-to-front crash tests this summer and develop computer simulations for further research.

90.   New computer simulations show support for this theory, scientists reported last month at a meeting of the American Geophysical Union in Boston.
