RISElement Level System Identification with Unknown Input with Rayleigh Damping
Publisher: American Society of Civil Engineers
Abstract: A novel system identification procedure is proposed for nondestructive damage evaluation of structures. It is a finite element-based time-domain linear system identification technique capable of identifying structures at ...
Gated Communities and Market-Dominated Governance in Urban China
Publisher: ASCE
Abstract: Approximately 300,000 gated communities (GCs) are distributed across urban China, presenting challenges to Chinese urban governance. Previous studies show interest in the relationship of GCs and security maintenance, and ...
Autonomous Navigation and Nonlinear Control for Quadrotors in a Structured Environment
Publisher: American Society of Civil Engineers
Abstract: This paper deals with the autonomous flight problem for a quadrotor. The quadrotor must reach its mission waypoints to complete a package delivery task autonomously while avoiding obstructing obstacles. A new linear matrix ...
Which Groundwater Remediation Objective is Better: A Realistic One or a Simple One?
Publisher: American Society of Civil Engineers
Abstract: One of the first steps in developing an optimal water resources design model is creating appropriate objective functions that represent the primary goals of the design. In many cases, one major objective is minimizing cost. ...

Abstract: This paper deals with the autonomous flight problem for a quadrotor. The quadrotor must reach its mission waypoints to complete a package delivery task autonomously while avoiding obstructing obstacles. A new linear matrix ...
Depletion Calculations for an Integral Small Molten Salt Reactor With Serpent
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The molten salt reactor (MSR) concept is among the Generation IV designs considered feasible for providing clean, safe, sustainable, and economical energy supplies to the world's population. The depletion of fuel for a ...
Hybrid Model for Pedestrian-Induced Lateral Vibrations of Footbridge Based on Pedestrian Phase Evolution and Inverted Pendulum Model: Simulation and Validation
Publisher: American Society of Civil Engineers
Abstract: The inverted pendulum model is currently a widely accepted pedestrian lateral force model in the study of pedestrian-induced lateral vibration. The inverted pendulum model proposes that pedestrians walking on a laterally ...
Evaluating an Electrokinetically Driven Extraction Method for Measuring Heavy Metal Soil Contamination
Publisher: American Society of Civil Engineers
Abstract: Measuring the heavy metal burden of “old contamination” soils (soils with aged contamination) can be challenging. Many laboratory procedures are currently in use and these can yield a wide range of burden estimates for the ...
Observations of Interannual Equatorial Freshwater Jets in the Western Pacific
Publisher: American Meteorological Society
Abstract: bservations of TRITON moored array salinity and temperature in the very wet western equatorial Pacific at 137°E, 147°E, and 156°E since the late 1990s reveal the importance of rainfall to the interannual flow and El ...
On the Dynamical Relationship between Equatorial Pacific Surface Currents, Zonally Averaged Equatorial Sea Level, and El Niño Prediction
Publisher: American Meteorological Society
Abstract: revious work has shown that for large zonal scales and low frequencies, wind-forced sea level, even near the equator, can be described by wind-forced long Rossby waves. In the eastern equatorial Pacific where the interannual ...
