A circuit which functions as a controlled negative-resistance is
described and analyzed; the circuit contains two transistors, a breakdown
diode, and five resistors connected in a stable feedback configuration.
From the analysis a set of design equations is derived.
An experimental circuit is described and a comparison between
measured performance...
As ornamental container nurseries face diminishing water allocations, many are looking to automated irrigation solutions to increase their water application efficiency. This thesis presents the findings of a study conducted at a commercial container nursery to determine 1) whether a capacitance or load cell sensor was better suited for monitoring...
Eight scale characters of known hatchery and wild coho salmon
(Oncorhynchus kisutch) were compared, and a linear discriminant
function was used to determine if hatchery and wild adult coho
salmon could be correctly identified by their scales. Eighty-two
percent of the hatchery and 89% of the wild fish were correctly...
This document describes the design and deployment of a first generation water vapor density sensing unit, the HumiSense. This device is based on an open, air-filled capacitor which is part of a resonant circuit. The frequency of the resonant circuit mixed with a fixed frequency oscillator is the basis of...
Seabirds are an integral component of marine ecosystems, however, because humans typically observe only snapshots of their lives at sea, our understanding of seabird foraging ecology is often limited. A more complete understanding of the ecological roles of seabirds and identification of critical foraging habitats requires the ability to follow...

William James came of age at a time of great social and intellectual change in the United States. During this period, new professional identities proliferated, and a new culture of professionalization developed with important ramifications for conceptions of individual and social identity. Professionalization was also closely related to key intellectual...
The Kittlitz's murrelet (Brachyramphus brevirostris) is a species of conservation concern over the entirety of its known range, which spans coastal Alaska and northeastern Russia. Concerns about the status of the species have been raised due to evidence of population declines in key breeding areas, low reproductive output, and perceived...

Themes of authorship in Aphra Behn's Oroonoko and Daniel Defoe's Robinson Crusoe highlight locations in the stories that expose the author's concerns with their responsibilities and contributions to society. In order to frame a discussion of authorship in Oroonoko and Robinson Crusoe, it is essential to position Behn and Crusoe...
