Moire tester detects small variations in flat conductor cable spacing by a quick, visual inspection. This device compares the cable to be tested with the negative of a very precise standard cable. The moire, consisting of bands of light and dark zones and its irregularities, can be interpreted as errors in spacing.
Time response correlation of vestibular adaptation in slow rotating environment with directed head movements
Linear estimator optimum for data on finite interval for restoration of images
Feasibility of measuring static temperature of flowing nitrogen in hypersonic wind tunnel
Atmospheric water vapor determined with passive microwave techniques
Direct measurement of skin friction in wind tunnel testing by using cholesteric liquid crystals
Stage separation using remote control release of joint with explosive insert
Ionospheric sounding for monitoring effective reflection coefficient of ground moisture
