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...
The purpose of the present study was to investigate the effect that Pell Grants have on Stafford Loan debt accumulation and to identify other factors that affect Stafford Loan debt accumulation.
The sample consisted of 32,525 dependent undergraduate students from more than 100 different four-year public institutions. All the students...
Productivity Interfirm Comparison (PIC) is a simple
method used to improve productivity at the firm level,
where a number of firms operate in the same product line so
that performance information on the firms can be compiled
and compared. This results in identifying potential areas
for improvement or exploitation. The...
Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...
Sound is a crucial aspect of the underwater environment for fishes – various species use sound to communicate, identify predators, navigate, and many other activities needed for survival in their habitat. Disruptions and disturbances in the natural soundscape can have important impacts on all these activities and are likely to...
Roundabouts have become an alternative for traditional intersections due to the safer operational performance. Previous research has provided crash modification factors (CMFs) as a criterion based on before-after studies as to evaluate the safety performance of roundabouts. One drawback of assessment based on crash modification factors, however, is that a...
The Family and Medical Leave Act of 1993 guarantees mothers twelve weeks of unpaid, job-protected leave to care for and bond with a newborn child, however, upon implementation only 45 percent of workers were covered by this law due to strict eligibility requirements and the proportion of eligible workers is...
The purpose of this study is to develop accuracy enhancement techniques for the Time
Domain Reflection/Transmission (TDR/T) measurements including the analysis of the
error sources for the Enhanced Accuracy TDR/T (EA-TDR/T). These TDR/T techniques
are used for IC and IC package interconnect characterization and equivalent circuit model
extraction, which are...
A project funded by the Southern California Edison (SCE) Company, Research
Center of Irwindale, California, has supported the development of a performance and
parameter prediction software program for use during the refurbishment of large
synchronous machines, turbine generators, and synchronous condensers. The computer
program was developed for SCE to allow...
