  • A 90.5dB DR 1MHz BW Hybrid Two Step ADC with CT Incremental and SAR ADCs

    Creator:
    Wang, Yanchao
    Abstract:
    The sensors in real time data processing IoT devices require high resolution and sub-MHz data converters, usually implemented as Incremental ADCs due to the advantages of oversampling technique and low latency. In discrete time incremental (IDT) ADCs, the sampling switch non-linearity, charge injection degrade the resolution, and power hungry OPAMPs...

  • A Quantitative Analysis of Simultaneous Supply and Demand Disruptions on a Multi-Echelon Supply Chain

    Creator:
    Kost, Austin R.
    Abstract:
    Modern supply chains have grown to be far more complex than their predecessors, as global trade and accessibility have opened avenues of trade that were previously impossible. As such, the inherent risk of internal and/or external disruptions impacting the performance of a supply chain has also grown due to the...

  • Automatic Classification of Ultrasonic Harbor Porpoise Clicks in a Varying Noise Environment

    Creator:
    De Leon, Daniel
    Abstract:
    This study compares three approaches in the design of an autonomous machine listening agent that predicts harbor porpoise ultrasonic echolocation clicks in diverse noise environments. Considering the temporal variations of noisy coastal ocean soundscapes which the harbor porpoises inhabit, we propose a leave-one-day-out (LODO) cross-validation strategy in the training of...

  • Econometric Analysis of Private Decisions on Renewable Natural Resources

    Creator:
    Zhao, Zichu
    Abstract:
    Natural resources play a crucial role in human society by providing both market value and non-market value. Effective management of these resources is necessary to achieve a balance between economic value and other non-market benefits. Econometric studies focusing on natural resource management help us understand the costs and benefits of...

  • Empirical Analyses of Forestry Interactions with Climate Uncertainty and Threatened Species

    Creator:
    Johnson, Kelsey K.
    Abstract:
    Forests are highly valuable resources providing both timber as well as many non-use values like habitat for various endangered and threatened species, carbon sequestration, and recreation, to name a few. Given that there are 765 million acres of forestland in the United States, almost 60% of which are privately owned,...

  • Empirical analyses of the impact of climate-induced natural disturbances on the economic value of U.S. forests

    Creator:
    Wang, Yuhan
    Abstract:
    Forests provide a wide range of timber and non-timber products along with providing a range of ecological services and support for biodiversity. Climate change poses various risks to forest health, as it can disrupt tree growth functions and trigger natural disturbances that increase tree mortality. In recent decades, altered disturbance...

  • Estimating the Influence of the Urban Heat Island Effect on Housing Prices

    Creator:
    Hossain, Lima
    Abstract:
    Using summertime housing transactions data of 3,309 parcels from multiple years in Eugene-Springfield, OR, we present a hedonic price model to estimate the influence of the urban heat island (UHI) effect on housing prices in this metropolitan area. By taking advantage of the inherent random nature of summertime weather observations,...

  • Estimating the Value of Water for Irrigation in Deschutes County, Oregon Utilizing a Hedonic Pricing Model

    Creator:
    Zimmerman, Grant J.
    Abstract:
    This thesis uses a hedonic price model to estimate the value of water for irrigation in Deschutes County, Oregon. The analysis uses a dataset comprising information on 2,274 agricultural parcels across the County. Uniquely, the analysis successfully utilizes assessor-determined real market values in the place of actual land sales. A...

  • Foraging ecology of barred owls where they are outcompeting the threatened northern spotted owl

    Creator:
    Baumbusch, Ryan C.
    Abstract:
    Following European-American colonization of North America and associated landscape changes, barred owls (Strix varia) underwent a dramatic expansion of their historical range. The barred owl expanded across the previously tree-less Great Plains that had limited their distribution, and into the forests along the west coast. In these western forests they...

  • gm/ID Design Techniques for Low-power High-performance CMOS Analog Integrated Circuits

    Creator:
    Aueamnuay, Chaiyanut
    Abstract:
    The gm/ID-based design of analog integrated circuits introduced in 1996 employs an empirical transistor sizing methodology using SPICE-generated lookup tables that enables good agreement between simulations and specifications. This thesis introduces a new SPICE lookup table that extends the gm/ID approach to the Miller pole-splitting frequency compensation of the classical...
