The concept of a Critical Path Scheduling Tableau is introduced
as an integrating tool for solving industrial engineering problems
involving the application of transitive graphs.
The Tableau is a combination of a precedence matrix and a
boundary time table which may be used to construct graphical representations
for critical path...
Instruments which combine the features of a digital-to-analog
conversion and a linear-to-logarithmic scale change usually perform
the digital-to-analog conversion first. These instruments are accurate
to within five or ten percent over ranges of five or six decades.
This thesis presents a method which uses combinatorial logic
to perform the linear-to-logarithmic...
Three species of true firs in the Pacific Northwest--Abies gran-dis, grand fir; A. amabilis, Pacific silver fir; and A. lasiocarpa,
subalpine fir--are severely damaged or killed by an imported insect
pest, the balsam woolly aphid (Chermes (Adelges) piceae Ratz.), Infestations of this insect cause abnormalities in the wood and, in...
This field investigation was designed to further
the understanding of the significant influence which
parent population density, as well as dispersion, have
on the dynamics of enclosed populations of the montane
vole, Microtus montanus (Peale). The study was conducted
in Klamath County, Oregon from June, 1963 to February,
1964. The...
Forest crop improvement through the application of genetic principles
has been recognized as an important factor in forest management.
The use of hybridization and selective breeding in forest tree
improvement points to the urgency of maintaining "pollen banks" of
superior trees.
The objective of this study was to determine the...
The indicated sum of a real scalar and a real or imaginary
vector is called a scator. Either the scalar part or the vector part
may be null. Scators generalize the complex variable to n-space.
The algebra of scators is not generally associative under multiplication
but the commutative and distributive...
Phospholipids of Tenebrio molitor larvae were
separated on columns of DEAE-cellulose and silicic acid-Hyflo Super Cel. The major phosphatide components were
identified by various analytical procedures.
Phosphatidyl choline was demonstrated to be the
predominant phospholipid with a high percentage of
phosphatidyl ethanolamine. A small amount of inositol-containing
phosphatides were present....
The present study was designed to investigate the relationship
of milk production and milk quality to growth rate and certain organ-oleptic
measurements of lambs of mutton breeds, Nine mature ewes
in their fourth lactation of the Border Cheviot, Dorset Horn,
Columbia, Suffolk, and Willamette breeds were acquired making a
total...
With the advent of underground testing, the study of the propagation of seismic signals has become of great importance. This thesis investigates the design of electrical analogs to represent the propagation of seismic waves. The analogs developed allow for the study of the effects of variations in the characteristic constants...
This investigation studies the relationship of the reflectivity in
the radar beam depicted by the radar echo patterns to the computed
reflectivity at surface observing stations under the radar beam.
Drop size distributions at stations in the Oregon State University
Mesometeorological Network during the storm period of 27-30 March
1963...
