Over the past two decades, the western United States has experienced many of the costliest and most severe wildfires in history. To mitigate the effects of the growing threats posed by wildfires, residents in at-risk communities are encouraged to protect their homes and property by adopting Firewise recommendations. This article...
In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...
A primary aim of bereavement research is to alleviate suffering and promote well-being at the junction of life and death for the survivor in an attachment relationship. Bereavement research in the last decade has focused primarily on examining grief recovery within the context of intrapersonal processes. This emphasis has often...
This thesis describes a study of the synthesis, stereochemistry,
and reactivity of cobalt(III) cysteinato (CyS) and related thiolato complexes.
The preparation of [Co(en)₂CyS]⁺ resulted in a product solution
containing a mixture of diastereomers in the ratio 2.3:1 (Δ:A). The isomers were separated by ion exchange chromatography, and
their absolute configurations...
A real-time neutron radiography system has been
developed at Oregon State University which is capable of
producing neutron radiographs of objects and events
concurrent with the incident radiation. The purpose of
this thesis is to demonstrate the feasibility of the
real-time technique as a further application of neutron
radiography at...
The breeding biology and early life history of the Tufted Puffin (Fratercula cirrhata) were studied for two years on Goat Island, Curry County, Oregon. Artificial nest boxes were used to minimize disturbance and provide easy access to puffin eggs and chicks. Utilization of these boxes was 47.5% and 57.5% in...
Recent work has shown that AdaBoost can be viewed as an algorithm that maximizes the margin on the training data via functional gradient descent. Under this interpretation, the weight computed by AdaBoost, for each hypothesis generated, can be viewed as a step size parameter in a gradient descent search. Friedman...
Governments have employed special capital gains taxes to curb speculation in real estate and raise public revenue. Economic theory suggests that the introduction of a gains tax with a declining rate structure over time will induce prospective buyers to reduce their demand for land and will induce sellers to offer...
Four aspects of the ecology of members of the Monotropoideae (achiorophyllous
Ericaceae, referred to here as "monotropes") are presented: (1) a clarified conceptualization
of monotrope nutrition based on a detailed literature review, (2) the relationship of
monotrope populations to the plant communities of Limpy Rock RNA, (3) a test of...
