RISActive Disturbance Rejection Control for Hypersonic Flutter Suppression Based on Parametric ROM
Publisher: ASCE
Abstract: This paper presents an active disturbance rejection control algorithm (ADRC) to suppress the hypersonic flutter of a three-degrees-of-freedom (3-DOF) two-dimensional (2D) airfoil operating in multiparameters space. In this ...
Lifetime Resilience Measurement of River-Crossing Bridges with Scour Countermeasures under Multiple Hazards
Publisher: ASCE
Abstract: River-crossing bridges are often subject to multiple hazards, including foundation scour, seismic attacks, and environmental degradation. When river-crossing bridges are in service, they should be restored rapidly after ...
Mobile Hyperspectral Imaging for Material Surface Damage Detection
Publisher: ASCE
Abstract: Many machine vision–based inspection methods aim to replace human-based inspection with an automated or highly efficient procedure. However, these machine-vision systems have not been endorsed entirely by civil engineers ...
Lifetime Resilience Migration Quantification Using Nonparametric Distance Metrics and Application for River-Crossing Bridges
Publisher: ASCE
Abstract: Quantitative resilience assessment is an essential to the lifetime management of civil structures. With the uncertainties arising from both physical and socioeconomic dimensions, resilience needs to be measured probabilistically. ...
Structural Material Condition Assessment through Human-in-the-Loop Incremental Semisupervised Learning from Hyperspectral Images
Publisher: American Society of Civil Engineers
Abstract: Engineering materials in constructed systems in service exhibit complex patterns, including structural damage, environmental artifacts, and artificial anomalies. In recent years, machine vision methods have been extensively ...
Spatial Transform Depthwise OverParameterized Convolution Recurrent Neural Network for License Plate Recognition in Complex Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Automatic license plate recognition (ALPR) system has been widely used in intelligent transportation and other fields. However, in complex environments such as vehicle sound source localization, poor illumination, or bad ...
Geometric Attention Regularization Enhancing Convolutional Neural Networks for Bridge Rubber Bearing Damage Assessment
Publisher: ASCE
Abstract: Rubber bearing condition evaluation is crucial for bridge inspection, and the current practice heavily relies on human-vision inspection. Convolutional neural networks (CNNs) have shown great potential for structured damage ...
Evaluating Contributions of Emerging Technologies to Civil Infrastructure System Resilience. I: A Decision-Making Workflow
Publisher: American Society of Civil Engineers
Abstract: Adopting emerging technologies (ETs) and enhancing civil infrastructure (CI) system resilience is a coupled process spanning technological, organizational, social, and economic dimensions, which concern both CI stakeholders ...
Evaluating Contributions of Emerging Technologies to Civil Infrastructure System Resilience. II: Case Studies
Publisher: American Society of Civil Engineers
Abstract: Many emerging technologies are gaining attention in the civil engineering industry that claim to be able to aid in how civil infrastructure is constructed, monitored, or operated. At the same time, building and managing ...
