ABSTRACT
Tracking a guided missile on a test range now is the only way to make sure of its performance. At one Department of Defense facility this is done by planting batteries of cameras or photo-theodolites along a 100-mile course. During its flight, the missile position is recorded by each camera at 100 frames per second, together with the camera training angles. Formerly these thousands of pictures from each of many cameras were turned over to a crew of computers, to determine just what happened. It took 2 weeks to make the calculations for a single flight. Now this is done on the International Business Machines (IBM) Card-Programmed Electronic Calculator in about 8 hours, and the tests can proceed.

A binocular stereo effect parameter calculator towards visual comfort
VRST '18: Proceedings of the 24th ACM Symposium on Virtual Reality Software and TechnologyBinocular stereoscopic contents may cause visual discomfort due to inappropriate settings of the parameters in production and display. In order to avoid this issue, the authors designed a calculator which can provide optimal parameters in 3D ...
