  • Semi-volatile organic compounds as molecular markers for atmospheric and ecosystem transport

    Creator:
    Genualdi, Susan A.
    Abstract:
    The use of semi-volatile organic compounds (SOCs) as molecular markers to identify the contributions of regional and long-range atmospheric transport, as well as current and historic sources, and contaminant deposition in remote ecosystems of the Western U.S. was investigated. Trans-Pacific air masses influenced by Siberian biomass burning events had elevated...

  • Storage Battery Chemistries with Earth Abundant Charge Carriers

    Creator:
    Hong, Jessica Junghwa
    Abstract:
    The demand for the development of sustainable energy is an all time high as we burn through limited fossil fuel reserves and as environmental concerns rise every year. Renewable energy sources such as wind and solar power have limitations due to inconsistent power supply that cannot meet the regular needs...

  • The Structural Characteristics of Robustness in Large-Scale Complex Engineered Systems

    Creator:
    Walsh, Hannah S.
    Abstract:
    Modern engineered systems are increasingly integrated into society, decentralized, and interconnected. However, scale and complexity create unique challenges in system design, such as emergent behavior and unintended consequences. This work investigates the structural characteristics of robustness in complex engineered systems by identifying patterns of under-recognized vulnerabilities at various levels of...

  • Traditional Agriculture in Transition: Continuity and Change in Southwest China

    Creator:
    Li, Xiaoyue
    Abstract:
    This dissertation seeks to understand Yi farmers’ livelihoods in the midst of an agricultural transition in Yunnan, Southwest China. This dissertation examines a community’s traditional knowledge related to wild edible plants (WEPs), analyzes socio-ecological vulnerability and resilience in the face of agricultural transition from subsistence farming to cash cropping, and...

  • Convergence Analysis Framework for Fixed-Point Algorithms in Machine Learning and Signal Processing

    Creator:
    Vu, Trung
    Abstract:
    Iterative algorithms are simple yet efficient in solving large-scale optimization problems in practice. With a surge in the amount of data in past decades, these methods have become increasingly important in many application areas including matrix/tensor recovery, deep learning, data mining, and reinforcement learning. To optimize or improve iterative algorithms,...
