  • An Interdisciplinary Agent-based Evacuation Modeling Framework: Seeking Convergence of Social, Natural, and Engineered Systems to Improve Life Safety in the Cascadia Subduction Zone

    Creator:
    Chen, Chen
    Abstract:
    Social scientists have studied people's responses to disasters for many decades, and behavioral commonalities and variations are summarized in different mental schemes/models in disaster studies. Integrating those findings from social science into evacuation simulation can improve simulation accuracy and eventually better support decision-making and disaster preparedness. However, this kind of...

  • Crowdsourcing Data-driven Development of Bicycle Safety Performance Functions (SPFs) : Microscopic and Macroscopic Scales

    Creator:
    Chen, Chen
    Abstract:
    While riding bicycles has been promoted for its health, economic, and environmental benefits, it also complements other modes to complete a safe, efficient, and reliable transportation system. However, the dramatic increase of bicycle usage in the U.S. is accompanied by a growth of bicycle crashes. The U.S. Department of Transportation,...

  • 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...

  • Nonlinear diffraction theory by an eigenfunction expansion of the Green's function

    Creator:
    Chen, Min-Chu
    Abstract:
    A second-order nonlinear diffraction theory is developed for a large diameter circular cylinder under the action of surface gravity waves of finite amplitude in water of-finite depth. Boundary value problems are derived by using a perturbation expansion and the solutions for the diffracted waves are given in terms of Fredholm...

  • 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...

  • 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...

  • Influence of transport parameters on the fresh and hardened characteristics of ready-mixed concrete

    Creator:
    Chen, Jiaming
    Abstract:
    Most specifications for ready-mix concrete (RMC) limit mixing time to 90 minutes and/or truck drum revolution counts (DRC) to 300 before discharge. These specifications have been in place for many years with the objective of ensuring the quality and performance of the finished concrete product. However, limited research has been...

  • Evaluation of selected marginal aggregates stabilized with cement

    Creator:
    Chang, Chen
    Abstract:
    Coastal Oregon is deficient in quality construction aggregate. There is, however, an abundance of lower quality, or marginal aggregate available for construction purposes. The purpose of this report is to develop techniques for upgrading marginal aggregates with portland cement and methods for evaluating the relative performance of these stabilized materials...

  • Tsunami inundation : estimating damage and predicting flow properties

    Creator:
    Wiebe, Dane Michael
    Abstract:
    The 2004 Indian Ocean and 2011 Tohoku tsunami events have shown the destructive power of tsunami inundation to the constructed environment in addition to the tragic loss of life. A comparable event is expected for the Cascadia Subduction Zone (CSZ) which will impact the west coast of North America. Research...

  • Investigation of Multi-constellation RTK GNSS Survey Productivity and Coordinate Accuracy

    Creator:
    Jamieson, Marian H.
    Abstract:
    This study evaluates the productivity and accuracy of surveys completed with single-base real-time kinematic (RTK) Global Navigation Satellite Systems (GNSS) using four different GNSS constellation combinations: (1) GPS-only, (2) GPS+GLONASS, (3) GPS+Galileo+BeiDou, and (4) GPS+GLONASS+Galileo+BeiDou. For this comparison, we set up a test site consisting of 20 stations ranging with...
