  • Modelling of on-chip spiral inductors for silicon RFICs

    Creator:
    Melendy, Daniel
    Abstract:
    In high-frequency circuit design, performance is often limited by the quality of the passive components available for a particular process. Specifically, spiral inductors can be a major bottle-neck for Voltage-Controlled Oscillators (VCOs), Low-Noise Amplifiers (LNAs), mixers, etc. For designers to correctly optimize a circuit using a spiral inductor, several frequency-domain...

  • High-performance low-power microprocessor circuits

    Creator:
    Hsu, Steven K.
    Abstract:
    This thesis will discuss two critical components of a digital system -- domino logic styles and flip-flops. In today's microprocessors, both domino logic and flip-flops are essential to high-performance and low-power design. Two new domino logic styles are presented and analyzed, Double Edge Triggered (DET) and Double Data Rate (DDR)...

  • High-performance delta-sigma analog-to-digital converters

    Creator:
    da Silva, Jose Barreiro
    Abstract:
    Multi-stage delta-sigma (ΔΣ) architectures, commonly known as MASH, are the preferred choice for analog-to-digital converters (ADCs) used in broadband communication applications, where high-resolution (above 14 bits) and high-bandwidth (several MHz) performances are required. Current state-of-the-art designs are capable of as much as 5-MS/s output data rates with 90-dB SNR. However,...

  • Seasonal movement, residency, and migration patterns of Wilson's Snipe (Gallinago delicata) across the annual cycle in the Willamette Valley of Oregon.

    Creator:
    Cline, Brittany B.
    Abstract:
    Studies of avian movement ecology afford essential insights regarding species' life histories, population dynamics, habitat and resource requirements, and other ecological relationships. While it is widely recognized that events in different stages of the annual cycle have important implications for processes in avian ecology, evolution, and conservation, challenges associated with...

  • Modeling and application of multispectral oceanic sun glint observations

    Creator:
    Luderer, Gunnar
    Abstract:
    The atmospheric radiative transfer model MOCARAT was developed and is presented in this thesis. MOCARAT employs a Monte Carlo Technique for the accurate modeling of band radiances and reflectances in an atmospheric system with a ruffled ocean surface as a lower boundary. The atmospheric radiative transfer is modeled with consideration...

  • Essays on environment and the spatial distribution of economic activities

    Creator:
    Wang, Chunhua
    Abstract:
    Environmental quality and the spatial distribution of economic activities affect each other in many ways. The primary purpose of this dissertation is to contribute to understanding the complex interrelationship and its policy implications. This dissertation consists of three essays. The first essay examines the roles that locational amenities and increasing...

  • Ultraviolet radiation as an environmental stressor of amphibians

    Creator:
    Bancroft, Betsy A.
    Abstract:
    My thesis explored the effects of and potential mediating mechanisms for an important environmental stressor, ultraviolet-B (UVB) radiation. UVB radiation has negative effects on organisms in both terrestrial and aquatic systems. I used meta-analysis to quantify the effects of UVB radiation on a diversity of aquatic organisms (Chapter 2). UVB...

  • Supplemental feeding influences reproductive success of the Hawaiian goose (Branta sandvicensis) at Haleakala National Park, Maui, Hawai'i

    Creator:
    Tamayose, Joy
    Abstract:
    Low reproductive success has been typical of high elevation populations of the Hawaiian goose (Branta sandvicensis) or nēnē. Researchers identified predation and inadequate nutrition as limiting factors. Reproductive success remained low in most years despite on-going predator control programs. I used a supplemental feeding program over two breeding seasons in...

  • Precursors for mitochondrial DNA replication : metabolic sources and relations to mutagenesis and human diseases

    Creator:
    Song, Shiwei
    Abstract:
    It is well known that the mitochondrial genome has a much higher spontaneous mutation rate than the nuclear genome. mtDNA mutations have been identified in association with many diseases and aging. mtDNA replication continues throughout the cell cycle, even in post-mitotic cells. Therefore, a constant supply of nucleotides is required...
