  • Reductive, dechlorination of sediment-sorbed polychlorinated biphenyls by vitamin B₁₂(subscript s)

    Creator:
    Trobaugh, Darin James
    Abstract:
    The reductive dechlorination of chlorobiphenyls in sediment by titanium(III) citrate-reduced vitamin Bus was studied in batch reactors. Long term ampoule studies demonstrated reductive dechlorination of sediment-sorbed 2,3,4,5,6-pentachlorobiphenyl (2,3,4,5,6-PeCB) to tetra-, tri-, di-, and monochlorobiphenyl products. Over 50% chlorine removal was observed over 160 days. The results of the ampoule experiment...

  • Removing Residual Lane Markings to Reduce Driver Confusion

    Creator:
    Weber, Jane B.
    Abstract:
    When pavement markings on roadways are removed, scarring can occur leaving behind traces of where the marking used to be called ghost lines. These ghost lines can confuse drivers on the roadway and divert their attention from the correct lane markings leading them into the false lane. Previous research has...

  • Radiometric Calibration of EAARL‐B Bathymetric Lidar Data

    Creator:
    Wilson, Nicholas C.
    Abstract:
    The Experimental Advanced Airborne Research Lidar ‐ B (EAARL‐B), which was built and deployed by the U.S. Geological Survey (USGS) in 2014, is a novel topographic‐bathymetric lidar system. While retaining a number of features that were pioneered in the original National Aeronautics and Space Administration (NASA) EAARL system (e.g., low...

  • An Experimental Study on Violent Geysers in Vertical Shafts

    Creator:
    Elayeb, Ibrahem S.
    Abstract:
    A Geyser in a stormwater (SW) and combined sewer system (CSS) is an oscillatory and violent release of a mixture of air and water through vertical shafts. Violent geysers are highly destructive. In the case of combined sewer systems, many municipalities operate their systems at a fraction of their maximum...

  • Nonlinear oscillations, bifurcations and chaos in ocean mooring systems

    Creator:
    Gottlieb, Oded
    Abstract:
    Complex nonlinear and chaotic responses have been recently observed in various compliant ocean systems. These systems are characterized by a nonlinear mooring restoring force and a coupled fluid-structure interaction exciting force. A general class of ocean mooring system models is formulated by incorporating a variable mooring configuration and the exact...

  • Deterministic and stochastic behaviors of a piecewise-linear system

    Creator:
    Mha, Ho-Seong
    Abstract:
    The (nonlinear) response behavior of a piecewise-linear system is investigated under both deterministic and stochastic excitations in this study. A semi-analytical procedure is developed to predict the system behavior by evaluating the joint probability density functions of the Fokker-Planck equations of the stochastic piecewise-linear system under random excitations via a...

  • Pull-Oriented Faculty Development: A Multiple, Descriptive-Explanatory Case Study

    Creator:
    Barner, Matthew S.
    Abstract:
    Traditional faculty development programs aimed at disseminating research-based pedagogy and innovations at potential adopters have helped increase awareness of these innovations; however, their adoption into engineering classrooms has been limited. This paper aims to present an alternative, pull-oriented approach to faculty development where faculty participants co-develop curricular innovations with engineering...

  • Stochastic analysis of a nonlinear ocean structural system

    Creator:
    Lin, Huan
    Abstract:
    Stochastic analysis procedures have been recently applied to analyze nonlinear dynamical systems. In this study, nonlinear responses, stochastic and/or chaotic, are examined and interpreted from a probabilistic perspective. A multi-point-moored ocean structural system under regular and irregular wave excitations is analytically examined via a generalized stochastic Melnikov function and Markov...
