To control stepping motors, the balance bridge power drive circuit is made up by TDA1521 integrated audio power amplifier, the pulse allotter is made up by the parallel ports of computer and latches.
The jitter is less than 3ns when the switch breakdown at front edge under the pluse with 400ns risetime, while the jitter shorts to about 1ns under the pulse with 80ns risetime.
To resolve that, wto-order charging circuit is used to reduce the stretching discharge, and dipulse is used to increase the reliability of the idscharge, which can decrease the failure discharge.
The ships are fitted with C- and S-band monopulse tracking radar, Cinetheodolite laser ranging and tracking system, velocimetry system, and onboard computers to track and control the spacecraft.
Brazing quality and product reliability are both increased as using high frequency pulse microplasma arc heating process for assembly brazing of cathode and photoetching grid of electron tube.
This article is introductions of subfebrile diagnosic and pulse magnetic field therapy for malignant tumour with a Humanbody Energy Detector and a Pulse Magnetic Field Therapy Instrument.
In this thesis, PCNN models and its actual application of medical image segmentation are studied.The Pulse Coupled Neuromime (PCN) structure and the mechanism of PCNN are discussed.
The imaging protocol for the mica samples consisted of a spin-echo pulse sequence with multiecho acquisition to collect images at seeral parallel echo times, the authors explained.
In this superradiance harmonics, the temporal width of harmonics is extremely short, the ratio of high harmonic fundamental wave is much higher than the known superradiance harmonics.
The result indicated that transformation of perlite was accelerated and the quantities of ferrolites was increased under the function of impulse electric field at second stage graphitization.
The exploratory testing study of modifying and fining the solidification structure of concast steel billet is carried out in concast production by the technology of electro-pulse modification.
Generalized UWB-ATR receiver is proposed, in which the local template waveform is computed as the average of the channel responses to nonfinite M transmitted reference pulses.
This perspective makes sense if you simplify the workings of a complex brain, exposing it to an array of electrical pulses; cells in plants also communicate through electrical signals.
And the players who wear bands feel this movement as waves or pulses around the body almost inside the body and that gives them the timing of the music.
These are not mythical creatures with pointy ears but merely the abbreviation for emission of light and very low-frequency perturbations due to electromagnetic pulses sources.
