This report is concerned with the analysis of the effect of
finite wordlength, channel capacity and source rate in digital feedback
control of linear systems. The cases considered are (1) finite
wordlength A/D conversion, no feedback delay, ideal ROM (read
only memory) controller; (2) finite A/D wordlength (source rate),
state...
The cities of Corvallis and Philomath, Oregon,
have, over the last three decades, grown both spatially
and in numbers of people. This study examines the
attractions and constraints to growth between the two
cities. The most notable constraint to growth is the
fact that the soils in the study area...
The Purpose of the Study
The central purpose of this study was to determine if certain
personality characteristics differ between community college persisters
and those who drop out of school. The following 12 a priori
hypotheses involving six Adjective Check List personality scales were
tested:
1. Male persisters would have...
The two classic theories of the distribution of
cities in an urban system are the rank size rule
and central place theory. The rank size relationships,
as incorporated into G. K. Zipf's Principle
of Least Effort, is seen as the result of a balancing
of the opposing forces of urban...
An attempt was made to differentiate between runs of steelhead by comparing the reassociations of their DNA. Conditions for the reassociation were studied using E. coli DNA, and observations
were made spectrophotometrically. Of the five buffers examined, 1.0 molar sodium perchlorate plus one-hundredth molar tris-HCl, pH 7.1, at 60° or...
A group of trout that reside in streams of the desiccating lake
basins of southeastern Oregon differ markedly from other known
Salmo. Known commonly as the red-band trout, this fish was subjected
to chromosome analysis for comparison with other species of
western North American Salmo. The karyotype of the red-banded...
DNA reassociations, measured by optical and double label
membrane filter techniques, were used to assess genetic relationships
among Aeromonas and enterobacteria. Aeromonads from human
sources, food, fresh water, fish, and pet turtles were examined. The
base compositions of three A. salmonicida isolates were 58% G+C
while the base compositions of...
This study examines the spatial characteristics
of the seafood processing industry on the Oregon Coast.
Three study areas are discussed: the Astoria area, the Newport
area, and the Coos Bay area. The industry is categorized
by four types of seafood processors. Types and
uses of processing and nonprocessing space are...
