RISA Strain Gradient Model for Fracture Prediction in Brittle Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a new model to predict the fracture in brittle materials from a geometrical weakness presenting an arbitrary stress concentration. The main idea is to combine the ...
Comparison of Three GIS-Based Hydrological Models
Publisher: American Society of Civil Engineers
Abstract: Three geographic information system (GIS)-based distributed hydrological models were developed for flood simulation and forecasting in a subbasin of the Yellow River. A grid-and-topography-based distributed hydrological ...
Impacts of Different Types of ENSO on the Interannual Seesaw between the Somali and the Maritime Continent Cross-Equatorial Flows
Publisher: American Meteorological Society
Abstract: AbstractThe impacts of different types of El Niño?Southern Oscillation (ENSO) on the interannual negative correlation (seesaw) between the Somali cross-equatorial flow (CEF) and the Maritime Continent (MC) CEF during boreal ...
Analyzing the Inundation Pattern of the Poyang Lake Floodplain by Passive Microwave Data
Publisher: American Meteorological Society
Abstract: he soil wetness condition is a useful indicator of inundation hazard in floodplains, such as the Poyang Lake floodplain. Special Sensor Microwave Imager (SSM/I) passive microwave data were used to monitor water-saturated ...
Moisture Damage of Asphalt Based on Adhesion, Microsurface Energy, and Nanosurface Roughness
Publisher: ASCE
Abstract: To explore the influence of water on the multiscale adhesive behavior between asphalt binder and aggregate, the nanosurface morphology and microsurface energy of asphalt binder and the macrobonding force between the asphalt ...
Using DMSP/OLS and NPP/VIIRS Images to Analyze the Expansion of 21 Urban Agglomerations in Mainland China
Publisher: ASCE
Abstract: This study combines the Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) nighttime light data with the Suomi National Polar-Orbiting Partnership satellite visible infrared imaging radiometer ...
A Planning Control Strategy Based on Dynamic Safer Buffer to Avoid Traffic Collisions in an Emergency for CAVs at Nonsignalized Intersections
Publisher: ASCE
Abstract: Intelligent traffic control at nonsignalized intersections under a connected and automated vehicle (CAV) environment can reduce traffic congestion, vehicle emissions [e.g., carbon dioxide (CO2), carbon monoxide (CO), ...
YOLOv5-LC: Enhancing Vehicle Detection for Evening Rushing Hour
Publisher: American Society of Civil Engineers
Abstract: In order to address the challenges of low lighting and overlapping vehicles in the detection of vehicles during the evening rush hour, this article proposes a new model YOLOv5-LC based on YOLOv5s. First, to solve the problem ...
Research on the Slurry Diffusion and Load-Bearing Characteristics of Postgrouted Piles in Loess Areas
Publisher: American Society of Civil Engineers
Abstract: Collapsibility significantly impacts the bearing capacity of pile foundations in loess areas. To improve the load-bearing capacity of piles, the pile-base postgrouting technique is widely used worldwide. However, there are ...
Effect of Mixed Hydrogen Natural Gas on the Flow Field of Bypass PIG Using CFD
Publisher: American Society of Civil Engineers
Abstract: Hydrogen energy is a new growth point for building a green and low-carbon industrial system and creating industrial transformation and upgrading. Large-scale hydrogen energy supply faces problems, such as lack of infrastructure ...
