S-matrix computations for quantum transitions, considering close coupling case of homonuclear diatomic molecular rotational excitation
A regulated dc-to-dc converter requires negligible standby power for the operation of critical electronic equipment. The main operating circuitry consumes power intermittently according to load conditions, rather than constantly.
Six-cup, low-inertia anemometer combines high resolution and fast response with a unique ability to sense only the horizontal component of the winds fluctuating rapidly in three dimensions. Cup assemblies are fabricated of expanded polystyrene plastic.
Communication system combines range acquisition system and time measurement system for tracking high velocity aircraft and spacecraft. The range acquisition system uses a pseudonoise code to determine range and the time measurement system reduces uncontrolled phase variations in the demodulated signal.
Preferred classification of calderas and volcano- tectonic depressions based on relative amounts of lava and proclastic ejecta
Stratospheric circulation from Tiros 7 satellite radiometrically derived temperature patterns
Venus map, discussing two dimensional technique using radar range and Doppler shift for study of surface
Explore the source record for details and available documents.
Laser microprobe facility is effective in the elemental analysis of small areas of heterogeneous samples. The instrument uses the focused beam of a pulsed laser to evaporate a small volume of material from a relatively massive sample.
Backward-diode pressure transducer retains the advantages of a tunneling mechanism, requires no shunting resistor, operates at a low voltage level, and consumes little power.
Mechanical properties of stabilization booms for gravity gradient studies on Applications Technology Satellites
Electronic spectra of Aurora Borealis using Aerobee rockets
Decreased intensity of myocardial respiration and oxygen metabolism as age factors
Telemetry system used by satellites to transmit observation to ground
One strip method of integral relations applied to inviscid supersonic blunt body problem
Late type stars with emission peak wavelength approximating graphite Debye frequency induced by graphite impurity atoms
Cultured mammalian cell growth morphology studied in situ with scanning electron microscope, discussing surface morphology changes during mitotic cycle of Chang liver cells
