Time series from the input and the output of a process are
analyzed by spectral estimation methods to develop a system transfer
function. Existing process data were used. All the published computation
methods were examined. Three of these have been explained
and illustrated.
The three methods for computing autospectra and...
A method has been devised for the digital recording of mass
spectra and for reduction of the data by means of the CDC-3300 digital
computer. The computer program *MASSPEC was developed to reduce
the digital data obtained from a rare-gas mass spectrometer.
The author devised a method of determining peak...
A long path dc plasma arc operated in an atmosphere of
argon is described. The arc is easily ignited and operated, and
is inexpensive to use. Samples were introduced into the arc as
solution aerosols. Radially resolved emission measurements are
reported for calcium, copper, and hafnium. The detection limit
for...
Stacked sheets of polyethylene terephthalate andpolystyrene provide a means
for recovering projectiles travelling at hypervelocities. The transparency of these
multiple diaphragms is utilized so that light generated from hypervelocity impacts
can be studied.
A method for gathering visible as well as ultraviolet light from less
transparent polymer foams has been...
