  • A Computational Framework for Resilience-Informed Design

    Creator:
    Hulse, Daniel E.
    Abstract:
    It is desirable for complex engineered systems to perform missions efficiently and economically, even when these missions' complex, variable, long-term operational profiles make it likely for hazards to arise. It is thus important to design these systems to be resilient so that they will actively prevent and recover from hazards...

  • Insights into Centennial-Scale Salt Marsh Morphodynamics from the Oregon Coast

    Creator:
    Peck, Erin K.
    Abstract:
    Quantification and comparison of morphological changes over the last ~300 y in Oregon salt marshes provide valuable insights into the tectonic, hydroclimatic, and anthropogenic processes shaping this important intertidal zone. Understanding of the rates and drivers of salt marsh change contextualizes intertidal habitats within the sediment routing system (i.e., source...

  • Using signaling to aid computer program comprehension

    Creator:
    Gellenbeck, Edward M.
    Abstract:
    Guidelines for using style to improve computer program comprehension have often been proposed without empirical testing. This thesis reports on the results of three controlled experiments that investigated ways program style may be used to aid comprehension of source code listings. Experiments 1 and 2 were conducted using advanced computer...

  • Machine learning methods for public policy : simulation, optimization, and visualization

    Creator:
    McGregor, Sean
    Abstract:
    Society faces many complex management problems, particularly in the area of shared public resources such as ecosystems. Existing decision making processes are often guided by personal experience and political ideology rather than state-of-the-art scientific understanding. This dissertation envisions a future in which multiple stakeholders are provided with computational tools for...

  • Essays in incomplete agricultural markets

    Creator:
    Cross, Robin M.
    Abstract:
    Agricultural revenues, the product of stochastic prices and yields, lead to markets which are incomplete, thereby entreating and complicating economic inquiry. The following three essays explore the incomplete nature of agricultural markets and consider the implications of incompleteness for a range of policy questions and economic tools. The first essay,...

  • Learning and Improving Policies for Probabilistic Planning Problems

    Creator:
    Issakkimuthu, Murugeswari
    Abstract:
    In this work, we study the problem of learning and improving policies for probabilistic planning problems. In the first part, we train neural network policies for probabilistic planning problems modeled as factored Markov decision problems. The objective is to train problem-specific neural networks via supervised learning to imitate the action...

  • Water Efficiency for Urban Landscapes in Semi-Arid Environments

    Creator:
    Martinson, Richard W.
    Abstract:
    Urban landscape water use is increasingly a focus of water conservation efforts. This is especially true in the arid and semi-arid regions of the western United States where increased demand, environmental concerns, and extended periods of drought have created chronic water shortages. However, until recently, little attention has been paid...

  • 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...

  • Essays on Regional Economic Impact Assessment and Demand Analysis using Disaggregated Data

    Creator:
    Chen, Yunguang
    Abstract:
    The appropriate use of disaggregated economic data not only improves the accuracy and robustness of economic analyses, but also extends the existing economic models to address new aspects of the issue. This dissertation consists of three essays: two essays use disaggregated economic-engineering data to address spatial heterogeneity in economic losses...
