  • Collection and analysis of evaporative flux data for various climates

    Creator:
    Katul, Gabriel
    Abstract:
    Daily evaporative flux and meteorological data from three sites were collected and analyzed. Analysis included evaluation of several reference evapotranspiration estimating methods which were theoretically based on distinct physical laws. The estimating methods included pan evaporation, energy-based Priestly-Taylor, and combination methods with and without biological adjustments. The data set represented...

  • Development of the simplified method to evaluate dynamic mechanical analysis data on asphalt-aggregate mixtures

    Creator:
    Ab-Wahab, Yunus Bin
    Abstract:
    Testing of asphalt binders and asphalt-aggregate mixtures using dynamic mechanical analysis is becoming popular with improvements in high-speed computers, precision equipment, and computer software. Researchers are trying to describe the behavior of asphalt binders and asphalt-aggregate mixtures in terms of their time- and temperature-dependent linear viscoelastic behavior. The objectives of...

  • Flexible membrane wave barrier

    Creator:
    Thompson, Gary O.
    Abstract:
    This report details the derivation of an analytical model for a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column by a moored cylindrical buoy on the free surface and fixed to a hinge at the seafloor. The analytical model combines...

  • Analytical framework for modeling scale-related variabilities in remote sensing

    Creator:
    Chen, Chaur-fong
    Abstract:
    A general analytical framework was established to investigate the scale-related variabilities in remote sensing. The variabilities were studied first by investigating canopy structure, canopy interaction with light, relation between spectral reflectance and plant phenological parameters. The variabilities simulated by the plant model were compared with the actual spectral data acquired...

  • Requirements for successful irrigation systems in the Senegal River Basin (Mauritania)

    Creator:
    Abba, Fatima Zahra
    Abstract:
    Implementation of a small-scale irrigation project in southern Mauritania is analyzed in this report. The main objective is to demonstrate that small-scale irrigation farming is the best suited solution for Mauritania's agriculture. To reach this objective different steps are taken in this study. The first step highlights the different aspects...

  • A mathematical model for adsorptive bubble-separation processes

    Creator:
    T'ang, Li
    Abstract:
    Adsorptive bubble-separation processes are used to remove adsorptive contaminants from wastewater. A mathematical model was developed for the adsorptive bubble separation processes in a countercurrent column. The model included an assumption that linear adsorption of the solute occurred on the gas bubbles. Predictions indicated that aqueous column height has less...

  • Three dimensional dynamic video position sensing

    Creator:
    Jansky, L. Andrew
    Abstract:
    A comprehensive system to locate and track objects in two or three dimensional space, using non-contact video sensing techniques is described. The need exists to be able to quantify range and proximity of objects that would be difficult or impossible to measure using standard contact based sensor technology. Available video...

  • Development of performance based test procedures for asphalt mixtures

    Creator:
    Kliewer, Julie E.
    Abstract:
    In 1987, Congress authorized a 5 year $150 million dollar research program called the Strategic Highway Research Program (SHRP). SHRP was divided into four major areas, including the asphalt research program. The asphalt research program was divided into six major research contracts, one such contract, SHRP-003A was called Performance Related...

  • Development of a mechanistic overlay design procedure for flexible pavements

    Creator:
    Zhou, Haiping
    Abstract:
    This dissertation describes the development of a mechanistic overlay design procedure. The mechanistic analysis represents a new trend in both new pavement and overlay design. The greatest advantage of the mechanistic pavement analysis is that it considers the fundamental characteristics of materials to be used, is capable of considering changes...

    Hron, Martha
    Abstract:
    With the passage of the American with Disabilities Act (ADA) it has become a civil rights violation to deny access to persons with disabilities to public transportation. The ADA requires transit agencies to provide accessible buses or equivalent services to persons with mobility, sensory or cognitive impairments. This study examines...
