  • A Direction-Sensitive Radiation Detector for Low-Altitude, UAV-based Radiological Source Search

    Creator:
    Becker, Eric M. (Eric Matthew)
    Abstract:
    Many devices and methods for radiological searches are currently being developed, including scanning using simple detectors, mapping using large-volume detectors, and Compton imaging using 3-D position sensitive detectors. However, these devices are typically expensive and the methods used require long periods of time to generate a direction or location. The...

  • Wirelessly Powered cm-Scale Sensor for Small Insect Localization Application

    Creator:
    Kang, Jian
    Abstract:
    The prevalence of Internet-of-Things (IoT) applications leads to an increasing focus on the design and optimization of sensor nodes. Battery lifetime and associated costs of battery replacement often limits the long term operation and viability of sensor nodes. RF wireless energy harvesting on the other hand can be appealing since...

  • Institutional Support for Queer International Students in U.S. Higher Education

    Creator:
    Wall, Rylan R.
    Abstract:
    Within the United States, international student enrollment in institutions of higher education has been climbing sharply over the past decade. However, despite this increase, colleges and universities largely do not adequately support these student and their unique needs within higher education. International students who identify as lesbian, gay, bisexual, trans,...

  • Habitat management for beneficial insects on Willamette Valley vegetable and berry farms

    Creator:
    Russell, Michael C.
    Abstract:
    Conservation biological control involves manipulating farm landscapes or management systems to enhance populations of beneficial predators of agricultural pests. Farmscaping is one aspect of conservation biological control where predators of important pests are identified, the availability on the farm landscape of resources and habitat components needed by the beneficials to...

  • Making the Unconscious Unconscious : Reclaiming Microinteractions for People with Motor Disabilities

    Creator:
    Lazewatsky, Daniel A.
    Abstract:
    Numerous diseases and injuries can limit a person's ability to perform everyday tasks -- things like getting dressed, bathing, and eating. Anything that requires physical activity can be affected; even simple things like turning on the lights can become difficult or impossible. Until recently, the only way for a person...

  • Out on a limb : Serving students at one community college branch campus

    Creator:
    Norby, Paula
    Abstract:
    More than any other single factor, access to community college education depends on proximity. The advent of the community college branch campus has opened higher education to broader segments of the population. The purpose of this study was twofold: 1) to discover services that students who attend a branch campus...

    Creator:
    Drage, Kimberly T.
    Abstract:
    For over 25 years organized groups of low-income families in Oregon have been gathering food that would otherwise go to waste and distributing this food among organization members. The purpose of this research study is to explore the potential for these organizations (gleaning groups) to contribute not only to food...

  • Level of physical activity and duration of moderate-to-vigorous physical activity among youth with visual impairment

    Creator:
    Kindinger, Kerstin
    Abstract:
    Physical activity is increasingly recognized as a maj or component contributing to the promotion of a healthy lifestyle. Evidence exists that a physically active behavior is carried over from childhood to adolescents and possibly to adulthood. Limited research about the physical activity behavior of students with visual impairment is available,...

  • Comparison of baits for monitoring the spotted wing Drosophila, Drosophila suzukii

    Creator:
    Kleiber, Joseph R.
    Abstract:
    Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe...

  • Reduced order modeling of legged locomotion in the horizontal plane

    Creator:
    Wickramasuriya, Gamika Arun
    Abstract:
    Sprawled-posture insects exhibit a remarkable ability to rapidly run in a stable manner over complex terrain, a feat that has yet to be equaled by man-made legged robots. Recent experimental results suggest that these insects may employ a hierarchical control structure, in which locomotion performance emerges from a combination of...
