  • Comparison of Vermont and Oregon statutory land surveyor laws

    Creator:
    Norton, Robert Leon
    Abstract:
    Land use planning, zoning, and subdivisions are integrally tied to the land resource. The need for a land surveyor and for statutes which govern his operation when working in these areas is stressed. A brief history of Vermont and Oregon, illustrating the role of land surveys on settlement, is given....

  • Lidar-based Post-earthquake Pavement Damage Classification System

    Creator:
    Shakya, Suzanna
    Abstract:
    3D laser scanning has been used extensively in engineering reconnaissance surveys to capture perishable data in an efficient, reliable, and precise manner. Many insights on damage can be obtained from the data through various methods of post-processing; however, many of these techniques are often labor intensive. This delay reduces the...

  • An investigation of the feasibility of a cutbank slope design method based on the analysis of natural slopes

    Creator:
    Keener, Quentin Roosevelt
    Abstract:
    The failure of cutbanks is a major problem encountered by those who construct low-cost roads in naturally forested residual soils. Attempts have been made to lessen the severity of failures by classifying certain soil areas as to their susceptibility to failure, in addition to bringing past design experience into play...

  • Analysis of dichotomous response models for low-dose carcinogenic risk estimation

    Creator:
    Tabesh, Taraneh
    Abstract:
    Several dichotomous-response models of carcinogenesis are discussed and their implications for low-dose risk estimation are examined. In addition, a pharmacokinetic model incorporating non-linear kinetics is studied and the results are investigated with respect to multiple-pollutant exposures. None of these models appears to suggest the existence of "thresholds". The analysis of...

  • A Methodological Approach for Structural Health Monitoring of Mass-Timber Buildings Under Construction

    Creator:
    Baas, Esther J.
    Abstract:
    As mass-timber building construction rises around the globe, there exists the need to verify the long-term, in-situ behavior and performance of these structural systems. Structural health monitoring (SHM), generally defined as a damage detection strategy consisting of a network of sensors, a data acquisition system, and algorithms for data analysis,...

  • The Application of Machine Learning Techniques on Marine Science Models

    Creator:
    Ellenson, Ashley
    Abstract:
    A variety of stakeholders require information about marine systems. In the open ocean, pilots of marine vessels require knowledge about environmental conditions for safe passage and route planning. On the coastline, communities rely on information about nearshore dynamics to increase safety from coastal hazards such as nearshore pollutants, coastal erosion,...

  • The effect of elevated pressure and high shear on oxygen uptake rates in activated sludge

    Creator:
    Streebin, Leale E.
    Abstract:
    The purification capacity of an activated sludge process is highly dependent of the rate of oxygen transfer from the air to the microorganisms. This rate can be increased in an air diffusion system by subjecting the culture to high shear and high pressure. A study of the effects of high...

  • Data Assimilation using Synthetic-Aperture Radar Imagery for Bathymetry Inversion at the Mouth of the Columbia River

    Creator:
    Harper, Spencer H.
    Abstract:
    Synthetic-aperture radar (SAR) imagery can provide wavenumber and frequency data to generate bathymetry estimates for locations where limited access or extreme ocean conditions can make standard bathymetry survey techniques difficult or impossible. The availability of SAR data could allow for regular bathymetry estimates of navigational channels providing insight into dredging...

  • Numerical Studies on Fluid-Structure Interaction and Applications

    Creator:
    Chen, Ming
    Abstract:
    Fluid-structure interaction (FSI) has been of significant research interest worldwide over the past several decades because of its variety of applications in both offshore and coastal engineering. Researchers analyzing FSI systems rely heavily on experimental tests in model scale in laboratories or large-scale sea trials. However, these tests are often...

  • Deterministic and stochastic control of nonlinear oscillations in ocean structural systems

    Creator:
    King, Paul E.
    Abstract:
    Complex oscillations including chaotic motions have been identified in off-shore and submerged mooring systems characterized by nonlinear fluid-structure interactions and restoring forces. In this paper, a means of controlling these nonlinear oscillations is addressed. When applied, the controller is able to drive the system to periodic oscillations of arbitrary periodicity....
