  • On the Imaging of Rip Currents in X-band Radar

    Creator:
    Kloster, Rebecca
    Abstract:
    Rip currents pose a serious danger to visitors of bathing beaches; they are also an important process in surf zone circulation. Haller et al. [2014] demonstrated that shore-based X-band radar can be used to compliment in situ measurements of rip currents. However, little is known of the underlying radar imaging...

  • Deep-sea sediment paleomagnetism : a case study from the North Atlantic

    Creator:
    Strano, Sarah Elianna
    Abstract:
    Sedimentary records from the North Atlantic, instrumental in the development of modern paleo-geomagnetic concepts, show a highly variable field even during times of constant polarity. Yet, our understanding of how the magnetization is acquired in the sediments is poorly understood. Primary magnetizations preserved in deep-sea sediments are known to be...

  • The behavior of economic agents and market performance

    Creator:
    Gokhale, Jayendra
    Abstract:
    This dissertation addresses issues concerning the behavior of firms, which has significant effects on performance. In the first study, we empirically investigate the effect of the reduction in number of firms on price competition in the U.S. macro-brewing industry. The number of macro brewing firms decreased from 766 in 1935...

  • Approaches for Characterizing Plant Physiological Responses to Environmental Stress

    Creator:
    Marias, Danielle E.
    Abstract:
    It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...

  • Teacher Candidates' Noticing of Instructional Features in the Context of an Ambitious Mathematics Teacher Education Program

    Creator:
    Maluangnont, Sasiwan
    Abstract:
    Teacher noticing is a necessary skill in order for teachers to elicit and respond to their students' mathematical ideas and support the ambitious learning goals of school mathematics. The purpose of this dissertation is to investigate what teacher candidates noticed about their teaching as they were provided supports and opportunities...

  • Numerical assessment of steel plate shear wall with coupling (SPSW-WC) system design procedure

    Creator:
    Li, Wennan
    Abstract:
    The Steel Plate Shear Wall (SPSW) system, is an innovative seismic lateral force resistant system, which has experienced increased use over the last three decades. The SPSW system is composed of boundary elements which anchor web plates that develop diagonal tension fields. A number of SPSW buildings have been built...

  • Mental Models of Mere Mortals with Explanations of Reinforcement Learning

    Creator:
    Anderson, Andrew A.
    Abstract:
    How should reinforcement learning (RL) agents explain themselves to humans not trained in AI? To gain insights into this question, we conducted a 124 participant, four-treatment experiment to compare participants’ mental models of an RL agent in the context of a simple Real-Time Strategy (RTS) game. The four treatments isolated...

  • New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

    Creator:
    Konrad, Kevin
    Abstract:
    Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

  • Prompt gamma neutron activation analysis of niobium for characterization of light interstitials

    Creator:
    Love, Ian J.
    Abstract:
    High purity niobium metal is used in the construction of superconducting radio frequency (SRF) cavities in superconducting particle accelerators, such as the Large Hadron Collider (LHC) at CERN or the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory. The usual method for characterizing the impurities in this niobium, the...

  • Development of an economical high temperature microchannel recuperator for solid oxide fuel cells

    Creator:
    Brannon, Samuel T.
    Abstract:
    To improve the performance of solid oxide fuel cells, a secondary power cycle can be driven by the recuperation of exhaust gas heat. Microchannel recuperators are attractive for waste heat recuperation due to compact form factors which also minimize the mass of the expensive superalloys required. This paper introduces a...
