Photomultiplier tube socket assembly with high gain and clean output signals for viewing organic scintillator light pulses
Input-output stability conditions of time-varying nonlinear feedback systems obtained, using concepts of loop gain, conicity and positivity
Cardiac output in man at rest and at work during and after acclimatization to 3,800 meters
One-stage, delay compensation amplifier, added to conventional univibrator circuitry time-synchronizes the trailing edge of the output pulse with the origin of the input pulse. The trailing edge is independent of the amplitude of the input pulse.
Dynamic programming input-output model of California educational system - correlation of educational variables to economic planning
Static dc to dc regulated converter using two-core output transformer
Bounded-input bounded-output stability of time- varying differential system analyzed through extension of Yoshizawa definitions and methods
Impedance cardiac output values simultaneously compared with dye dilution techniques under rest and exercise conditions
Longitudinal and lateral axes orientation of uniformly rotating or rapidly rotating vehicle utilizing outputs from solar sensors and lateral magnetometer
Output characteristics of electroetched rhenium surface, bare and cesiated work function and performance
Cardiac output during rest and work determined via carbon dioxide method at 3800 m altitude
Fourier analysis of amplifier commutated capacitor type integrator output signal
Cyclotron harmonic resonances in plasma frequency conversion output due to harmonic interactions with incident waves
Tool aids in graphic determination of input values for any first order lag system of known gain and time constant where the corresponding output function is displayed graphically and can be described by a first order differential equation. This tool permits a rapid reconstruction of input points.
Four-electrode impedance plethysmograph measures ventricular stroke volume of cardiac output of humans. The instrument is automatic, operates with only one recording channel, and minimizes patient discomfort.
Fluidic transducer gives a pressure output signal that is a direct function of the differential temperature sensed by the device. The transducer is arranged as a bridge.
Cardiac output and regional blood flow in conscious rats exposed to acute hypoxia
Economic impact analyses survey procedures, and input-output coefficient tables
