  • Exploring the potential for using deep-sea bamboo corals (Isidella sp.) for paleoceanographic reconstructions

    Creator:
    Hornung, Jonathan P.
    Abstract:
    Deep-sea bamboo coral (Isidella sp.) SE000901A from the southern Oregon coast (water depth 1048m) provides a high-resolution record of variability of North Pacific Intermediate Water (NPIW) and carbon rain to the sea floor, related to coastal upwelling, from 1808 to 2000AD. Counting of annual layers in magnesium to calcium (Mg/Ca)...

  • A spatially explicit method for determining the effects of watershed scale land use on stream conditions

    Creator:
    Kehmeier, Jonathan W.
    Abstract:
    The primary goal of this research was to identify the impacts that individual agricultural land uses have on fish communities in small streams located in the Willamette Valley of western Oregon. The diverse nature of the land use features of the valley provided a challenging but useful system for the...

  • The Cost of Caring: An Exploratory Study of the Professional Quality of Life of Early-Career SBAE Teachers in Oregon

    Creator:
    Schmidt, Kirby J.
    Abstract:
    The purpose of this research is to describe the secondary traumatic stress (STS) levels of early career school based agriculture (SBAE) teachers. Using the professional quality of life (ProQOL) scale (Stamm, 2010) as a theoretical framework, secondary traumatic stress, burnout (BO) and compassion satisfaction (CS) levels were measured among (n...

  • Bird-habitat relationships at multiple spatial resolutions in the Oregon Coast Range

    Creator:
    Brooks, Jonathan P.
    Abstract:
    I analyzed the relationship between avian abundance and landscape structure at five spatial resolutions for 30 subbasins in the central Oregon Coast Range using remotely sensed data and a geographic information system (GIS). I developed maps of forest successional stages from Landsat Thematic Mapper (TM) data at a spatial resolution...

  • Collaborative filtering with probability and collaborative filtering with privacy

    Creator:
    Yang, Min
    Abstract:
    "Collaborative filtering has seen considerable success in the areas regarding information overload and e-commerce, while the current developed systems are flawed in several respects. Two approaches, the distribution-based algorithm and the blurring profile solution, are proposed to address several outstanding issues. The main findings of this research include: • The...

  • ATRIAS 1.0 & 2.1 : enabling agile biped locomotion with a template-driven approach to robot design

    Creator:
    Grimes, Jesse A.
    Abstract:
    Practical bipedal robots need to be simultaneously efficient, robust, and versatile machines, but designing robots dynamically capable of these demands has been a significant bottleneck. We designed ATRIAS to be a highly dynamic biped capable of both walking and running untethered in real environments. To meet these goals, ATRIAS is...

  • A collaborative filtering algorithm and evaluation metric that accurately model the user experience

    Creator:
    McLaughlin, Matthew
    Abstract:
    "Collaborative filtering algorithms’ performances have been evaluated using a variety of metrics. These metrics, such as Mean Absolute Error and Precision, have often ignored recommendations for which they do not have data. Ignoring these recommendations has provided numbers which do not accurately represent the user experience. Qualitatively we have seen...

  • How to Render Mathematical Symbols in Java

    Creator:
    Sun, Yuemei
    Abstract:
    Current math software provides limited interactivity and dynamics when conveying math ideas. We are developing prototype Java toolkits to display math-embedded documents in a more dynamic and interactive way. The core task of current project is to create a Java implementation of a MathML (in which a math expression is...

  • Force and impulse control for spring-mass running

    Creator:
    Koepl, Devin N.
    Abstract:
    We present a novel control strategy for running which is robust to disturbances, and makes excellent use of passive dynamics for energy economy. The motivation for our control strategy is based on observations of animals, which are able to economically walk and run over varying terrain and ground dynamics. It...

  • Contributions to Collaborative Filtering Research

    Creator:
    Nong, Shuzhen
    Abstract:
    In this report, I first introduce three areas of interest to collaborative filtering researchers, namely: (a) how to solve the sparsity and scalability problems in recommendation systems; (b) how to rapidly develop and test collaborative filtering algorithms; and (c) how to apply collaborative filtering to unbounded numeric preference data. In...
