  • Coordination for Scalable Multiple Robot Planning Under Temporal Uncertainty

    Creator:
    Marcon dos Santos, Gilberto
    Abstract:
    This dissertation incorporates coalition formation and probabilistic planning towards a domain-independent automated planning solution scalable to multiple heterogeneous robots in complex domains. The first research direction investigates the effectiveness of Task Fusion and introduces heuristics that improve task allocation and result in better quality plans, while requiring lower computational cost...

  • Aboveground biomass and ecosystem carbon pools in tropical secondary forests growing in six life zones of Costa Rica

    Creator:
    Cifuentes Jara, Miguel
    Abstract:
    Carbon sequestration in tropical secondary forests growing in all climates must be quantified to understand their potential role in adaptation and mitigation strategies of global climate change. Total aboveground biomass (TAGB), soil carbon, and total ecosystem carbon (TEC) were measured in 54 secondary forests growing along a broad bioclimatic gradient...

  • Vertical structure and aboveground biomass of tropical forests from lidar remote sensing

    Creator:
    Gonçalves, Fabio Guimarães
    Abstract:
    Methods for obtaining accurate, spatially explicit estimates of biomass density in tropical forests are required to reduce uncertainties in the global carbon cycle, and to support international climate agreements and emerging carbon markets. Three-dimensional (3-D) remote sensing techniques sensitive to the vertical structure of vegetation provide a unique opportunity for...

  • A stratigraphic approach to characterize the deposition and storage of organic matter in reservoir sediments

    Creator:
    Stratton Garvin, Laurel E.
    Abstract:
    The relationship between carbon burial and sedimentation in reservoirs is unknown, exposing gaps in our fundamental understanding of the transport, processing, and deposition of sediment and organic matter in fluvial and lacustrine systems and contributing to uncertainty in our understanding of the net impact of dams to the global carbon...

  • Interpreting Climate of the Past from High-Resolution Ice Core Records of Methane

    Creator:
    Lee, James E.
    Abstract:
    Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...

  • Ocean Acidification Impacts on Bivalves at Multiple Organizational Levels: From Individual Larvae to Bivalve Aggregations Habitats

    Creator:
    Gimenez Calvo, Iria
    Abstract:
    Many marine bivalves are sensitive to ocean acidification (OA) stress and often show heightened sensitivity during brief early larval and post-larval life stages, potentially leading to population bottlenecks. Most of the evidence to date has been collected in laboratory experiments that focused on physiological responses at the organismal level under...

  • Investigating Provers' Understandings of Combinatorial Proof

    Creator:
    Erickson, Sarah A.
    Abstract:
    Enumerative combinatorics is an area of mathematics that is both highly accessible for students and widely applicable to other sciences and areas of mathematics (Kapur, 1970; Lockwood, Wasserman, & Tillema, 2020). One important class of problems in combinatorics is combinatorial proofs of binomial identities, which is a type of proof...

  • Integrating indigenous knowledge into the community development process : the Zimbabwean experience

    Creator:
    Munyaka, Golden
    Abstract:
    This study is a critical ethnography of my professional career as an educator born and raised in the Shona culture in Zimbabwe. In this metaphysical study I reconstruct a worldview that I consider to be representative of Shona customs and beliefs. Doing this project has challenged my own ethnic identity...

  • Marketing sophistication in the forest products industry

    Creator:
    Han, Xiaoou
    Abstract:
    In the forest products business and management literature, one common categorization of different types of innovation is product innovation, process innovation and business systems innovation. Forest products companies have long placed high emphasis on process innovations, which are related to yield maximization, manufacturing efficiency and operating costs reduction. This is...

  • Multiscale modeling of two-phase flows in microarchitectures with microfeatures

    Creator:
    Truszkowska, Agnieszka
    Abstract:
    Two-phase flows in microtechnology based devices are purposefully present in multiphase reactors, phase separators, analytical devices and others. Two-phase flows can also be an undesirable side effect occurring during operation due to phase transitions or, more commonly, introduction of surrounding air through equipment gaps and with process feed. In both...
