  • A procedure for estimating the carbon budget of terrestrial ecosystems in the former Soviet Union by geographic information system analysis and classification of AVHRR derived Global Vegetation Index

    Creator:
    Gaston, Greg G.
    Abstract:
    The purpose of this research was to develop methods for using geographic information system (GIS) analysis and unsupervised classification of Global Vegetation Index (GVI) images to improve carbon budget estimates of the former Soviet Union (FSU). A GIS was used to locate the geographic distribution and estimate the area of...

  • The great fires : Indian burning and catastrophic forest fire patterns of the Oregon Coast Range, 1491-1951

    Creator:
    Zybach, Bob
    Abstract:
    The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...

  • Assessing Exposures and Simplifying Complex Mixtures of SVOCs for Hazard Characterization using Alternative Model Systems

    Creator:
    Rivera, Brianna N.
    Abstract:
    Throughout their lifetime individuals are exposed to complex mixtures of chemicals. The study of chemical mixtures is an internationally recognized research priority, but seemingly complex challenge. To reduce the intricacy of studying mixtures, researchers have identified different prioritization methods based on exposure or the toxicity of chemicals. However, understanding the...

  • The Viability of Container-Based Sanitation as a Tool for Sanitation Coverage in Urban Haiti

    Creator:
    VanRiper, Froggi Ramona
    Abstract:
    Haiti is far from achieving the UN goal of sanitation access for all; 20% Haitians have no sanitation access, and less than 0.1% of urban excreta is safely managed. Container-Based Sanitation (CBS) may be a key tool for achieving equitable sanitation coverage in Haiti’s cities. CBS is a sanitation strategy...

  • Using DNA metabarcoding to describe biodiversity and disease dynamics

    Creator:
    Massey, Aimee L.
    Abstract:
    Land-use change, particularly in the form of the conversion of primary forest to forest-matrix systems, alters species communities and species interactions. Describing these often complex and nuanced species responses is one of the great challenges in ecology. Another complementary challenge is finding and using the most efficient means for collecting...

  • Learning-based Techniques for Fast and Robust Motion Planning

    Creator:
    Chow, Scott
    Abstract:
    Motion planning is a cornerstone of autonomous robots, enabling robots to safely and efficiently perform tasks such as package delivery, infrastructure inspection, and manipulation. However, as the field of robotics matures, robotic systems are being developed that (1) are challenging to analytically model, (2) require computationally expensive model-based controllers, and...

  • Characteristics of soil organic matter in two forest soils

    Creator:
    Crow, Susan E.
    Abstract:
    Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

  • Tracking of Melt Pool Motion Using Numerical Analysis of Laser Powder Bed Fusion

    Creator:
    Cox, Bryce
    Abstract:
    Laser Powder Bed Fusion (LPBF) is a process commonly used to create additively manufactured metal parts. The flexibility and complexity allowed by the LPBF process provides opportunity for significant advancement in multiple industries as parts can be customized in shape and function for specific needs. These benefits can be compounded...

  • Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

    Creator:
    Barlow, Dawn R.
    Abstract:
    The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...
