  • Mass transport in laboratory water wave flumes

    Creator:
    Kim, Tae In
    Abstract:
    A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

  • Curriculum synthesis and amelioration : a case study of undergraduate civil engineering

    Creator:
    Hamernik, Robert E.
    Abstract:
    The dynamic philosophy of education as applied to the undergraduate Civil Engineering program has been influenced by such factors as the introduction of new theories, the demands and needs of our society and the personnel responsible for teaching. These changes are reflected in the curriculum as witnessed by a historical...

  • Shrinkage study of high performance concrete for bridge decks

    Creator:
    Fu, Tengfei
    Abstract:
    In the field of civil infrastructure, bridge desks are typically constructed using high performance concrete (HPC). Concrete bridge decks demand qualities such as low permeability, high abrasion resistance, superior durability, and long design life. Over decades of field and laboratory experience, many HPC bridge decks have been found to be...

  • Knowing Concepts in the Social and Material Context of Engineering Practice

    Creator:
    Bornasal, Floraliza
    Abstract:
    It is expected that information taught in the context of school will ultimately transfer to workplace settings. To support this transition, educators and researchers advocate for organizing foundational ideas, or concepts, in specific domains of knowing. In the domain of transportation engineering, knowing of concepts, which include "big ideas" such...

  • Experimental and Analytical Studies of Large-Scale Pile Caps

    Creator:
    Al-Sakin, Yasmeen
    Abstract:
    Pile caps are structural elements used to transfer loads from columns to a group of piles, which transfer them to stronger soil layers. Pile cap with horizontal distance between the column and piles less than twice its effective depth is categorized as "deep," where significant nonlinear strain distribution occurs through...

  • A discrete numerical study of micromechanics of sand liquefaction

    Creator:
    Zhang, Lei
    Abstract:
    Liquefaction of saturated granular material due to cyclic loading can result in catastrophic damage to the built environment. The mechanics of liquefaction have been previously studied through field testing, physical modeling, laboratory experiments, and numerical simulations. However, significant questions remain with respect to the particle-scale behavior of granular materials during...

  • Experimental study of counter-propagating solitary wave collisions

    Creator:
    Chen, Yongshuai
    Abstract:
    To better understand the extreme local amplification of tsunami, the experimental investigation on counter-propagating solitary wave collisions over a horizontal bottom was conducted using the optical measurement techniques: Particle Image Velocimetry (PIV), and Laser Induced Fluoresce (LIF). Head-on collisions and oblique collisions of equal-amplitude as well as unequal-amplitude waves were...

  • 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...

  • Demonstration of a permeable barrier technology for the in-situ bioremediation of pentachlorophenol contaminated groundwater

    Creator:
    Cole, Jason David
    Abstract:
    A pilot scale demonstration of a biological permeable barrier was conducted in a pentachlorophenol-contaminated aquifer at a wood preserving facility. A permeable reactor was constructed to fit within a large diameter well. Arranged in series, a cylindrical reactor 24" x 36" (0.61 x 0.91m) (diameter x height) was partitioned to...

    Creator:
    Islam, Mohammad Rabiul
    Abstract:
    Traffic signal countdown timers (TSCT) are innovative, practical and cost effective technologies with the potential to improve efficiency and safety at signalized intersections. The purpose of these devices is to assist motorists in decision making at signalized intersections with real time signal change information. While successful implementation of these devices...
