Storm time whistler cut-off related to magnetospheric ring current during magnetic storm, noting formation of high energy high density plasma
Edge constraint effect on buckling of sandwich and ring stiffened conical shells under external pressure
Ring current effects on cosmic rays considering geomagnetic storms, Forbush decrease and time variations
Edge restraint coupling effect on buckling mode of ring stiffened shells of revolution
Flexible seal ring vibration induced by rotor surfaces, obtaining results in terms of natural frequencies and influence coefficients
Ring laser angle encoder with a scanning photometer autocollimator and an isolation axis, provides continuous digital readout. It measures the angular difference in inertial attitudes of target /any phenomena generating or reflecting a light beam/ two at a time relative to target one at a time.
Mass loading effects on vibration of ring and shell structures
Theory and test results of tensile strength of epoxy rings and belts reinforced by boron filaments
Optimal structural design for sandwich-shaped and ring-stiffened loaded shells of revolution
Electron impact induced fragmentation of ring D in steroids involving loss of carbon atoms analyzed by mass spectrometry
Fixed space planar thermionic diode with collector guard ring for studying various emitter materials, measuring emitter temperatures
Nonuniform ring current belt growth, discussing associated magnetospheric substorms
Crater distribution and population curves for Surveyor 1 vicinity, discussing Flamsteed P ring floor characteristics
Energy method analysis establishes parameters governing stability of circular rings acted upon by constant, uniformly distributed loads. Energy method is used so that nonlinear behavior of structure before buckling can be accounted for. Method affords conceptually superior basis for analyzing the axisymmetric deviation mode.
Circular ring stability analysis under uniformly distributed radial load
Vibration analysis on ring stiffened conical shell reentry configuration
Performance characteristics of liquid and solid lubricants for contacts of miniature slip-ring capsules
