Numerical Experiment of Aeroelastic Stability for a Rocket Nozzle
Publisher: American Society of Civil Engineers
Consistent Impacts of Surface Enthalpy and Drag Coefficient Uncertainty between an Analytical Model and Simulated Tropical Cyclone Maximum Intensity and Storm Structure
Publisher: American Meteorological Society
Abstract: Several previous studies have demonstrated the significant sensitivity of simulated tropical cyclone structure and intensity to variations in surface-exchange coefficients for enthalpy (Ck) and momentum (Cd), respectively. ...
GOES-16 Observations of Rapidly Intensifying Tropical Cyclones: Hurricanes Harvey (2017), Maria (2017), and Michael (2018)
Publisher: American Meteorological Society
Intelligent Pixel-Level Rail Running Band Detection Based on Deep Learning
Publisher: American Society of Civil Engineers
Abstract: The rail running band is a mathematical representation describing the continuous strip-shaped spatial surface resulting from the rolling contact operation of train wheels on the rail surface, which establishes a direct ...
Fusion of Convolution Neural Network and Visual Transformer for Lithology Identification Using Tunnel Face Images
Publisher: American Society of Civil Engineers
Abstract: This study proposes an intelligent method for recognizing the lithology of a tunnel working face by combining a convolutional neural network and visual transformer. First, an efficient method for collecting high-resolution ...
Policy Gradient–Based Focal Loss to Reduce False Negative Errors of Convolutional Neural Networks for Pavement Crack Segmentation
Publisher: American Society of Civil Engineers
Abstract: Convolutional neural networks (CNNs) have achieved tremendous success in pavement crack segmentation. However, it is difficult for CNN-based crack segmentation methods to minimize false-negative and false-positive errors. ...
Intelligent Detection of Sealed Crack with 2D Asphalt Pavement Images
Publisher: American Society of Civil Engineers
Abstract: Accurately identifying sealed cracks on asphalt pavement surfaces is of significant importance to pavement management. This paper proposes an efficient semantic segmentation model called Parallel-TDNet for pixel-level ...
Linking Atmospheric River Hydrological Impacts on the U.S. West Coast to Rossby Wave Breaking
Publisher: American Meteorological Society
Abstract: AbstractAtmospheric rivers (ARs) have significant hydrometeorological impacts on the U.S. West Coast. This study presents the connection between the characteristics of large-scale Rossby wave breaking (RWB) over the eastern ...
Study of SARS Transmission Via Liquid Droplets in Air
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microscale liquid droplets could act as the SARS carriers in air when released from an infected person through breathing, coughing, or sneezing. In this study, a dynamic model has been built ...
Automated Detection of Pavement Manhole on Asphalt Pavements with an Improved YOLOX
Publisher: ASCE
Abstract: Accurate recognition and location of pavement manholes are of great significance for pavement maintenance. This paper proposes an improved You only look once X (YOLOX) for automated detection of manholes on asphalt pavements. ...
