The design and operation of a completely automatic trigger
circuit is presented. This circuit differs from conventional trigger
circuits in that manual control adjustments are not necessary. It
will automatically provide stable triggering over a wide range of
trigger signal amplitudes, repetition rates and waveshapes. The circuit
consists of three...
The model-reference, adaptive control concept is based on the
precept that desired control system performance is a known design
requirement and can be obtained from a representative model. Control
system parameters are adjusted by the adaptive controller through a
minimizing operation on a function of the error (i.e., performance
index)...
The work in this thesis solves the problem of restoring a power
system to its operating stable equilibrium point, following a transient
disturbance, in minimum time without any oscillation. The idealized
power system considered consists of cylindrical rotor generator connected
to an infinite busbar with the following cases of control:...
Greenhouse and growth chamber experiments were conducted with
the following objectives: (a) to study the effects of N-1-naphthylphthalamic
acid (naptalam) on shoot and tuber production, rhizome transformation,
and growth of yellow nutsedge (Cyperus esculentus L.) plants;
(b) to study the effects of N-phosphonomethyl glycine (glyphosate) on
nutsedge plants at different...
