  • The lanceolate projectile point in southwestern Oregon : a perspective from the Applegate River

    Creator:
    Nisbet, Robert Alexander
    Abstract:
    Archaeological investigations of the Applegate Lake project area were conducted by the Department of Anthropology, Oregon State University Univerfrom 1977-1980. A cultural sequence believed to span over 8000 years was revealed from a series of six sites. Several of these sites contained lanceolate or leaf-shaped projectile points. A large serrated...

  • Elicitors: A Novel Tool for Controlling the Colorado Potato Beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae)

    Creator:
    Butcher, Alexander M.
    Abstract:
    Over the last several decades, potato production has increased globally as it has been recognized as an important component to improving food security. However, potato production has been continuously challenged by pests. Current pest management practices rely heavily on chemical pesticides. Unfortunately, the overuse of pesticides can be harmful to...

  • Dynamical System Scaling of Fuel Performance During Reactivity Insertion Accidents

    Creator:
    Dueñas, Alexander M.
    Abstract:
    Fuel qualification timelines for new fuel technology under ideal conditions can take between 20-25 years to be fully qualified from initial concept to deployment as full fuel assemblies. To reduce the timeline and costs, new separate-effects test and integral-effects test experiments, advanced instrumentation, and advanced modeling and simulation tools are...

  • On Avoiding Power-Seeking by Artificial Intelligence

    Creator:
    Turner, Alexander M.
    Abstract:
    We do not know how to align a very intelligent AI agent's behavior with human interests. I investigate whether—absent a full solution to this AI alignment problem—we can build smart {\ai} agents which have limited impact on the world, and which do not autonomously seek power. In this thesis, I...

  • Distance Estimation in Virtual Reality

    Creator:
    Alexander, Jonathan M.
    Abstract:
    Distance estimation is a key process for movement and spatial cognition. However, this process is hindered when navigating virtual environments in virtual reality (VR) due to the movement being exclusively visually simulated. In order to contribute to the understanding of how this hinderance effects our ability to estimate distances in...

  • Investigation of Drag Coefficient and Virtual Mass Coefficient on Rising Ellipsoidal Bubbles

    Creator:
    Dueñas, Alexander M.
    Abstract:
    Accurately describing drag and virtual mass forces in two-phase flows is crucial for high fidelity modeling of nuclear thermal hydraulic safety systems. This study compares existing drag coefficient correlations commonly used in computational fluid dynamics (CFD) applications for air bubbles to experimental data collected for ellipsoidal air bubbles of varying...

  • The Kalispel Tribe of Indian’s Contemporary Usage of Traditional Foodways

    Creator:
    Hilborn, Alexander M.
    Abstract:
    Native American traditional foodways serve as one of the most important resources for indigenous communities because these resources provide a variety of non-physical cultural assets and health benefits to Native groups through the medium of food. The demolition of North America’s foodways through colonization has had adverse effects on indigenous...

  • Membrane permeability properties of human granulocytes

    Creator:
    Vian, Alexander M.
    Abstract:
    In the last decade, there has been renewed interest in the use of granulocyte transfusions to treat infections in individuals with compromised immune systems. However, granulocytes only remain functional for about a day after isolation and this short shelf life is a significant drawback. Cryopreservation would allow long term storage...

  • Wind ramp prediction

    Creator:
    Alexander, Chianna M.
    Abstract:
    The number of wind turbines and wind farms in the Pacific Northwest has increased dramatically in the past six years, which represents a significant amount of electrical generation capacity connected to the public electric grid. However, the variable nature of wind sometimes introduces excessive power, or conversely shortages, in power...

  • High-Flux Thermal Management With Supercritical Fluids

    Creator:
    Fronk, Brian M. and Rattner, Alexander S.
    Abstract:
    A novel thermal management approach is explored, which uses supercritical carbon dioxide (sCO2) as a working fluid to manage extreme heat fluxes in electronics cooling applications. In the pseudocritical region, sCO2 has extremely high volumetric thermal capacity, which can enable operation with low pumping requirements, and without the potential for...
