  • Tidal range changes in the Delaware Bay : past conditions and future scenarios

    Creator:
    Hall, George F.
    Abstract:
    Throughout the Holocene, appreciable changes in bathymetry are hypothesized to have resulted in large changes to tidal datums in coastal and estuarine areas. An understanding of tidal change is an important contribution to the knowledge of relative historical sea-level change and future coastal planning. To test this hypothesis, the Advanced...

  • An Efficient Point Cloud Processing Framework for Terrestrial and Mobile Lidar Data via Reconstructing the Scan Pattern Grid

    Creator:
    Che, Erzhuo
    Abstract:
    Lidar (LIght Detection And Ranging) is a remote sensing technology using light in the form of a pulsed laser, which enables efficient, accurate, 3-D data acquisition of a scene. Depending on the mounting platform, lidar data acquisition can be categorized into Airborne Laser Scanning (ALS, or airborne lidar), Terrestrial Laser...

  • Optimal sensor placement for measuring operating speeds through curves on rural two-lane highways

    Creator:
    Mecham, Megan E.
    Abstract:
    Operating speed is one of the best performance measures that can tell transportation agencies how well or how poorly the transportation system is functioning. Fluctuating operating speeds often mean there is a design flaw or something about the physical road design that violates drivers' expectations. A primary example of this...

  • Finite amplitude deep water waves : a comparison of theoretical and experimental kinematics and dynamics

    Creator:
    Jensen, Robert E.
    Abstract:
    Problems associated with quantification of deep water wave kinematics and dynamics are examined. Summaries of Stokes' theory and Dean's stream function theory are reported. A computer algorithm is developed to solve the hydrodynamic characteristics for Stokes' fifth and third order and linear theories. Tests are initiated to verify the results...

  • The analysis of directional wave spectra from current and pressure measurements

    Creator:
    Lin, Li-hwa
    Abstract:
    Directional wave spectra have been estimated in this study based upon simultaneous subsurface measurements of current and pressure. Two previously developed methods, the stochastic and deterministic approaches, have been reviewed and restudied. It is demonstrated by means of the Correlation Theorem that the stochastic and deterministic approaches are, under certain...

  • Behavior of a compliant wave-current barrier

    Creator:
    Kerper, Dale R.
    Abstract:
    This study includes an analytical solution to the wave-current barrier interaction problem and large scale experiments to validate the theory. The boundary value problem is solved mathematically by characterizing the flow field and barrier motion separately, then coupling the relationships with the appropriate kinematic and dynamic boundary conditions. The flow...

    Rogge, Angela Anne
    Abstract:
    The educational environment is filled with different types of students, all with diverse learning styles. The Meyers-Briggs Type Indicator and Kolb’s Theory of Experiential Learning are generally accepted methods for determining and assessing a person’s preferred method of information processing. There has been research that suggests learning styles are specific...

  • An eigenvalue wave analysis of a fixed semi-immersed rectangular structure

    Creator:
    Steimer, Robert Bruce
    Abstract:
    The problem of a fixed rectangular structure of unit width in a train of simple harmonic normally-incident waves is modeled. The solution allows for variable (1) length and draft of structure, (2) differing depths in the three (fore, aft, and beneath the structure) distinct regions, and (3) wave period. The...

  • Impact of access density on number of crashes at commercial roadways

    Creator:
    Yi, Xiang
    Abstract:
    Numerous research efforts have proven the safety benefits of access management. There are several access management techniques, including unsignalized access spacing, signalized intersection spacing, left-turn lanes, right-turn lanes, Two-Way Left-Turn lanes (TWLTLs), nontraversable median, U-turns, interchange access separation distances and so on. This project explores the correlation between access density...

  • Normal acceleration characteristics of the leading vehicle in a queue at signalized intersections on arterial streets

    Creator:
    Zhu, Hong
    Abstract:
    Normal acceleration characteristics of passenger cars provide valuable information for various aspects of transportation engineering, including use in the geometric designs of intersections, freeway ramps, passing lanes, acceleration lanes, turning bays, or in the development of traffic simulation or fuel consumption models. However, the data used in previous studies are...
