This thesis deals with the output statistics of nonlinear devices.
It develops the classical output autocorrelation function in two dimensions
and extends the theory to three and four dimensions. Closed
form solutions for the output correlation function in two and three
dimensions are given for the full- and half-wave rectifier...
The merits of the photoelastic coating technique as applied to
wood were evaluated. Comparative tests were made on 12 nominal
two-by-four Douglas Fir boards. The object of these tests was to
determine the limitations of this technique, such as accuracy and
complexity of experimental procedure. Correlation of the experimental
results...
This paper develops an equation, from an heuristic set of assumptions,
which describes the axial current, leakage current, resultant
electric field, and resultant earth potential occurring when
a pipeline buried within a resistive earth is subjected to a distributed,
primary, axial, electrostatic field produced from a high-voltage, direct-current (HVDC) power...
The effects of boundary geometry on internal density currents
in a density stratified reservoir were investigated in a laboratory
model. When water was simultaneously withdrawn and admitted to
the reservoir, a complex current regime was established. The general
flow pattern is described, and the influence of physical variables
on the...
The effects of round, square, and reentrant entrances on flow
regimes and local heat transfer coefficients were determined using a symmetrical,
plane-wall two-dimensional, subsonic air diffuser with one
of the diverging walls heated and maintained isothermal.
Flow and heat transfer studies were made at total divergence
angles ranging from 0...
The thesis presented here is a quantitative study of vacant
urban land in Corvallis, Oregon. In order to present this study the
writer first studied the available literature and found that little had
been published dealing with causal factors of vacant urban land.
Rather, it was found that several writers...
The Timoshenko beam theory, as an engineering alternative to
the elementary and exact theories, introduces a factor, k', called
the shear coefficient which has been given various interpretations and
values. It is the objective of this study to experimentally evaluate
k' for a brass bar of rectangular cross-section.
Analytical results...
From the time when fluoroscopic screens were first used there
have been scattered references to reduction in their light output due
to age, use, etc. References are scarce and usually devoid of
quantitative data. A long-range program has been set up in an effort
to arrive at some meaningful information....
