  • Characterizing and Addressing Dataset Shift with Deep Learning

    Creator:
    Olson, Matthew L.
    Abstract:
    This dissertation delves into understanding, characterizing, and addressing dataset shift in deep learning, a pervasive issue for deployed machine learning systems. Integral aspects of the problem are examined: We start with the use of counterfactual explanations in order to characterize the behavior of deep reinforcement learning agents in visual input...

  • INDOEX aerosol optical depths and radiative forcing derived from AVHRR

    Creator:
    Tahnk, William Richard
    Abstract:
    The Indian Ocean Experiment (INDOEX) had as a primary objective determining the radiative forcing due to anthropogenic aerosols over climatologically significant space and time scales: the Indian Ocean during the winter monsoon, January-March. During the winter monsoon, polluted, low-level air from the Asian subcontinent blows over the Arabian Sea and...

  • The effect of ultra-high pressure on the emf of thermocouples

    Creator:
    Eide, Stuart Ames
    Abstract:
    The effect of ultra-high pressure on the thermal emf of a chromelialumel thermocouple is investigated using an indirect method which does not require a direct knowledge of the temperature of the pressurized junction. The unknown temperature is written parametrically as a function of a directly measured quantity, the electrical power...

  • Accessibility of highly conserved RNA sequences of Escherichia coli 70S ribosomes and implications for developing antibacterial agents

    Creator:
    Rahman, Mohammad A.
    Abstract:
    Escherichia coli 16S-like ribosomal RNAs from eubacterial, archaebacterial and eukaryotic organisms have several universally conserved sequence zones which are proposed to be single-stranded. A clear function for all of these regions has not yet been defined. To evaluate the roles of these sequence zones in protein synthesis, knowledge of their...

  • Accounting for Heterogeneity Corrections in Breast Brachytherapy

    Creator:
    Rogers, Kevin L.
    Abstract:
    Purpose: Model-based dose calculation algorithms (MBDCAs) have become clinically available within the past several years in commercially available brachytherapy planning systems. This work investigates the application of a 510(k) approved MBDCA Acuros™ BV and establishes a reproducible method of validation. The research is broken into three primary research goals. The...

  • Glucocorticoid regulation of salmonid B lymphocytes

    Creator:
    Tripp, Ralph A.
    Abstract:
    The in vitro effects of cortisol in regulating salmonid B cell functions were investigated. B cells at three distinct stages of differentiation were examined for cortisol sensitivity. B lymphocyte responses were examined 1) during the early stage of the precursor, 2) during the intermediate stage of differentiation associated with clonal...

  • Characterization of high temperature fatigue mechanisms in Haynes 282 nickel based superalloy

    Creator:
    Rozman, Kyle A.
    Abstract:
    Electric power needs will only grow over the next decades as more humans ascend from poverty into the middle class. Currently, the majority of electric power is generated by burning fossil fuels. To help mitigate the undesirable effects of burning fossil fuels research is being done to increase the efficiency...

  • Using Computational Studies to Characterize Aqueous Metal Clusters : From Spectroscopy to Stability

    Creator:
    Wills, Lindsay A.
    Abstract:
    In this dissertation, the spectroscopic properties and thermodynamic stability of a class of materials known as metal oxo and hydroxo clusters are studied. In aqueous solutions, many metals can aggregate into discrete clusters of metals bridged by oxo or hydroxo ligands. These clusters are of particular interest to us for...

  • Crossing Boundaries during Stress Responses: Antigen Presentation by Adaptive and Innate MHC Class I Molecules

    Creator:
    Nagamine, Brandy S.
    Abstract:
    The immune system is a complex network of cellular processes working in harmony to guard us against pathogenic attack. Of utmost importance is the ability of the immune system to discriminate between “self” and “non-self” and diseased versus healthy. Recognition of antigens complexed to major histocompatibility complex (MHC) molecules is...
