Fish and invertebrate distribution at multiple scales in Thomas Creek, Oregon : a transition from conifer uplands to agricultural lowlands

Creator:: Langshaw, Russell B.
Abstract:: Longitudinal patterns of fish and benthic invertebrate distribution and habitat use were similar in Thomas Creek, Oregon but clarity of these patterns differed. I studied fish and aquatic invertebrates simultaneously, at multiple scales, and used multivariate statistical techniques to compare responses to the same environmental conditions. Both types of organisms...

Nature in chains : the effects of Thomas Jefferson’s rectangular survey on a Pacific Northwest landscape

Creator:: Schweickert, Tina K.
Abstract:: Understanding the impact of humans on the environment has long been a topic of scholarly interest and debate. As environmental problems mount, accounts of historic ecological conditions and the factors of change become increasingly useful. This study considers competing schools of interpretation about human impacts on ecological landscapes and develops...

Spring irrigation management of perennial ryegrass (Lolium perenne L.) seed production

Creator:: King, Craig Millhouser
Abstract:: Introduction of later maturing cultivars of perennial ryegrass (Lolium perenne L.) places more seed production fields in a period of drought common to Oregon during vital stages of reproductive development. During these stages, the final yield of the crop is largely determined by the number of seeds set, and the...

College persistence stories of low income, first-generation students

Creator:: Jewett, Gretchen L.
Abstract:: Low income, first-generation college students face many barriers in their pursuit of a college degree. As a result, the retention rates for this student population have traditionally been lower than for other student populations. In order to support the persistence of this student population it is important to study the...

Trinexapac-ethyl and open-field burning in creeping red fescue (Festuca rubra L.) seed production in the Willamette Valley

Creator:: Zapiola, Maria Luz
Abstract:: Open-field burning has been an effective, economical, and widespread method of post-harvest residue management in creeping red fescue seed production in the Willamette Valley since the late 1940s. However, the use of field burning has been legislatively restricted due to air quality and safety issues. The foliar-applied plant growth regulator...

Evaluating online text classification algorithms for email prediction in TaskTracer

Creator:: Keiser, Victoria L.
Abstract:: This paper examines how six online multiclass text classification algorithms perform in the domain of email tagging within the TaskTracer system. TaskTracer is a project-oriented user interface for the desktop knowledge worker. TaskTracer attempts to tag all documents, web pages, and email messages with the projects to which they are...

Three methods for estimating subpixel cover fractions in coarse resolution imagery

Creator:: Damon, Diane L.
Abstract:: Coarse resolution imagery, such as that produced by the MODIS instrument, poses the challenge of estimating sub-pixel proportions of di erent land cover types. This problem is di cult because of the variety and variability of vegetation within individual pixels. This thesis describes and compares two existing algorithms for estimating...

Fabrication and characterization of thin-film electromagnetic coils and heaters for microchannel applications

Creator:: Dehuff, Nicole L.
Abstract:: The focus of this thesis involves developing general fabrication processes relevant to the manufacture of two new devices for the Microscale technology Energy and Chemical Systems (MECS) program at Oregon State University. The two MECS devices developed, capture dots and transparent thin-film heaters (TTFHs), require unique process development for successful...

Shrunken learning rates do not improve AdaBoost on benchmark datasets

Creator:: Forrest, Daniel L. K.
Abstract:: 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...

Determining contact angle of solutions with varying surface tension on dry and pre-wetted silica sands

Creator:: McGinnis, Thomas L.
Abstract:: Infiltration of highly concentrated solutions into unsaturated sand is suspected to be affected by the liquid-gas interfacial tension between the resident water and that of the infiltrating solution. The wetting of non-porous solid surfaces by liquids is commonly quantified by contact angle measurements. However, it is well known that wettability...
