Acoustic detection of microbubbles and particulate matter near the sea surface
(1965)
A pulse-echo system using an electrostatic transducer and
steel reflector was operated over the frequency range 24-192 Kcps
in the sea and in the laboratory. Excess attenuations from 0.15 to
1.1 db/M due to absorption ...
Optimal filter design for sampled data systems with illustrative examples.
(Monterey, California. Naval Postgraduate School, 1965)
A model for the study of fast transients on a D-C distribution system
(Monterey, California. Naval Postgraduate School, 1965)
Fast voltage transients have been found capable of disrupting the
operation of a proposed solid-state, ac-dc inverter system. A method is
proposed for studying the propagation of such transients in an involved
d-c power ...
Hybrid control system simulation.
(Monterey, California: U.S. Naval Postgraduate School, 1965)
Hybrid control systems are becoming increasingly important today due
primarily to the development of the high speed digital computer. This
work involves the hybrid simulation of a relatively simple second order
analog ...
An investigation into the use of very low frequency transmissions for ship navigation.
(Monterey, California: U.S. Naval Postgraduate School, 1965)
The very low frequency band has been characterized by
its extremely reliable propagation since the early days of
radio. Recent development of oscillators accurate to a few
parts in lO-H have made it possible to navigate ...
Application of Mitrovic's method to feedback compensation of sampled-data control systems.
(Monterey, California: U.S. Naval Postgraduate School, 1965)
An experimental investigation of the effects of position and motion on the frequency stability of certain crystal oscillators
(Monterey, California: U.S. Naval Postgraduate School, 1965)
Crystal oscillators are now available with frequency stabilities
10 11 of a few parts in 10 or 10 . One application of such stability
is in navigation systems, where geographic position may be determined
by phase ...
A generalized procedure for determining transient response of third order systems.
(Monterey, California: U.S. Naval Postgraduate School, 1965)
For any system whose input-output relationship may be
described by a ratio of polynomials in S (the complex number ѵ±jw),
one of the measures of the system performance is its transient
response to a step input. For ...
Computer investigation of a destroyer steam generator
(Monterey, California: U.S. Naval Postgraduate School, 1965)
Control of a real system by a time-shared computer
(1965)
Advances in digital computer technology have led to employment of
the computer as a control device. Although many theories for utilization
of the digital computer as the compensator in a position feedback control
system ...
