In this thesis we investigate the extension of certain theorems
of additive number theory to three algebraic systems. A generalization
of a theorem by Cauchy and Davenport on the cardinality of the
sum of two sets of residue classes is given. We obtain and compare
estimates for the order of...
The main focus was on developing an algorithm and supporting computer programs for use by extension personel to counsel farm managers on problems of enterprise choice. Investigation was initiated from the complete certainty viewpoint of linear programming. Upon introducing uncertainty, ramifications of changing expected income, variance and the correlation coefficient...
Few Americans are aware of the tremendous
recreation potentials along the banks of the Intracoastal
Waterway, mainly because they are unaware of
the existence and extent of the toll-free Waterway.
This study attempts to categorize and locate some of
the attractions that can be explored along the two
thousand miles...
Since the mid-1950's, when Western Kraft Corporation
began operation of a pulp and paper processing plant north of Albany,
Oregon, inhabitants of the Albany area have faced an air pollution
nuisance.
This study is an attempt to add empirical substance to the complaint
that air pollution reduces land values. The...
This paper reviews techniques that have been used to estimate bark growth, upper stem bark thickness, and bark volume. Two new equation forms have been developed and tested for estimating upper stem bark thickness using,as an example, data from Sitka spruce (Picea
Sitchensis (Bong.) Carr.) in southeast Alaska.
In recent years, studies indicate that the second formant
of normal speech contains the majority of the information necessary
for speech intelligibility. This thesis presents a system to
translate the second formant frequencies to within a more adequate
hearing range of the partially deaf.
The digital speech translator, DISTRAN, utilizes...
The land tenure system in the United States contains a variety
of tenure types. A major characteristic of this tenure system is the
continual change of tenure types within a given region. As these tenure
types change, problems of a cultural, economic, and legal nature
are created and interact with...
The properties of evaporated aluminum-oxide films were investigated. The characteristics of MOS devices
made with single-layer aluminum-oxide films and double-layer
films which were made by evaporating aluminum oxide
over thermally-grown silicon dioxide as gate insulation
have been investigated. Vacuum-evaporated aluminum oxide
has features which are suitable for fabricating MOS devices....
The extent of the competitive effect of wild oats on winter wheat
yield was estimated in field studies on three commercial wheat farms in
the Willamette Valley. The morphological development of the wild oat
plants was also documented.
Wild oats were removed from stands of wheat in six different treatments;...
The purposes of this study were to determine the effects of
temperature, nutrients, growth regulators, and culm detachment
during seed development on ryegrass seed dormancy and weight.
The effects of storage temperature on seed dormancy were also
studied.
Seed dormancy of annual (Lolium multiflorum Lam.) and
perennial (Lolium perenne L.)...
