RISStudy on the Seasonal Estuarine Turbidity Maximum Variations of the Yangtze Estuary, China
Publisher: American Society of Civil Engineers
Abstract: In this study, measurements were used to characterize the dry–wet seasonal factors that control hydrodynamics and sediment transport in the Deepwater Navigational Channel (DNC) located in the North Passage of the Yangtze ...
A Simplified Method to Calculate the Acoustic Pressure of Three-Dimensional Finite-Length Noise Barriers
Publisher: American Society of Civil Engineers
Abstract: To predict the performance of three-dimensional (3D) finite-length noise barriers, a simplified method is presented to calculate the acoustic pressure of noise barriers by a theoretical approach. Based on noise diffraction ...
Applying a Macroscopic Calibration to a Wiedemann Driver Behavior Threshold Study
Publisher: American Society of Civil Engineers
Abstract: A speed - flow graph is used to calibrate Wiedemann 74 model parameters. A parameter calibration platform integrating VISSIM, Matlab, and ExcelVBA is built, which minimizes the differences between the measured values and ...
Automatic Detection of Rail Surface Cracks with a Superpixel-Based Data-Driven Framework
Publisher: American Society of Civil Engineers
Abstract: A bilevel superpixel-based framework for the vision inspection of rail conditions and automatically detecting rail surface cracks is proposed in this paper. The simple linear iterative clustering (SLIC) algorithm is applied ...
