  • Modeling Atlantic Pelagic Longline Vessel Trip Costs

    Creator:
    Silva, George
    Abstract:
    The U.S. Atlantic pelagic longline fleet pursues highly migratory species (e.g., swordfish, tunas, and sharks) over an extensive range in the Atlantic, Gulf of Mexico, and Caribbean Sea. Because of the fleet’s diverse range and vessel characteristics, fuel can be a major component of vessel operating costs and can make...

  • Eugene Residents Risk Perceptions of Water Scarcity

    Creator:
    Leitermann, Lily
    Abstract:
    Potential water scarcity and drought conditions are predicted in and around Eugene, Oregon due to decreased snowpack and subsequent decreased snowmelt in the Western Cascade Mountains. This phenomenon was triggered by a long-term trend of warmer winters scientifically linked to global climate change patterns (Dalton et al. 2013). Numerous stakeholders,...

  • Master Negotiators and Creative Problem Solvers: A Survey of South African Women & Water-Use Case Studies

    Creator:
    Kirwan, Christina E. M.
    Abstract:
    Through a desk-top analysis, this research shows that South African women have gained and utilize specialized skills, behaviors, and adaptations through their daily activities which are useful when applied to water resource management. Further, South African women are shown to build and draw on social capital as a way to...

  • Laws, regulations, and management plans to improve streamflow and stream temperature : a case study in the North Fork Burnt River Watershed

    Creator:
    Morgan-Hayes, Anna S.
    Abstract:
    As the western United States faces warmer and increasingly varied climate conditions, as well as predicted water insecurity, concerns over water quality and water availability are growing. While humans, fish, and wildlife are dependent on clean water for survival in the present, management of water resources needs to consider future...

  • Investigating Timescales of Resurgence at Large Calderas: Post-74 ka Activity at Toba Caldera, Sumatra, Indonesia

    Creator:
    Mucek, Adonara E.
    Abstract:
    The Toba Caldera Complex is the youngest resurgent caldera in the last 100 kyrs, formed from four overlapping eruptions starting 1.2 Myrs ago. The last caldera-forming eruption, the Youngest Toba Tuff eruption, occurred ~74 kyrs ago, emitting 2800 km3 of ash and pumice into the atmosphere and forming the caldera...

  • Economic Contributions of Atlantic Highly Migratory Species Recreational Fisheries: U.S. Atlantic and Gulf of Mexico

    Creator:
    Hutt, Clifford, Silva, George, and Lovell, Sabrina
    Abstract:
    Highly migratory species (tunas, billfish, swordfish, and sharks or HMS) are pursued by a dedicated group of anglers that spend significant amounts in pursuit of these “big game” fish. From 2013 to 2016, NOAA Fisheries conducted the most comprehensive assessment of the economic impacts of HMS recreational fisheries in the...

  • 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,...

  • Secure Data Analytics under Data Integrity Attacks

    Creator:
    De Silva, Shashini A.
    Abstract:
    There has been tremendous growth in using data analytic and machine learning algorithms to make critical decisions, such as in the national power grid, healthcare operations, and autonomous vehicles. Employing data analytic for decision-making allows cyber attackers to manipulate the decisions of these algorithms through data falsification. Hence, the trustworthiness...
