RISDynamic Response of Multilayered Silty Seabeds under Wave-Current Action in the Yellow River Estuary
Publisher: American Society of Civil Engineers
Abstract: Few studies have focused on pore pressure and liquefaction in a layered silty seabed. This study investigated a silty seabed in the Yellow River Estuary. Based on Biot’s theory and further considering the influence of ...
A Novel Ejector with Water-Separator Function for Proton Exchange Membrane Fuel Cell System Based on a Transient 3D Model
Publisher: American Society of Civil Engineers
Abstract: The design and optimization of the hydrogen circulation system can improve the hydrogen utilization rate and overall system efficiency of the fuel cell system. The ejector and water separator are important parts of the ...
Effects of Microcapsules on Self-Healing Performance of Asphalt Materials under Different Loading Modes
Publisher: ASCE
Abstract: This study used two types of self-healing microcapsules to evaluate the healing performances of asphalt materials that contained different dosages of microcapsules under three different loading modes: shear, tension, and ...
Road Geometry Feasibility for Automated Vehicles with ACC Systems: Vehicle Dynamics on Curved Roads
Publisher: American Society of Civil Engineers
Abstract: Automated vehicles equipped with adaptive cruise control systems (ACC-AVs) are prevalent and the ensuing issue is the feasibility of ACC-AVs’ operation on the roads. This study investigates the feasibility of road horizontal ...
Molecular-Level Analysis of Oxygen and Asphalt Behavior on Aggregate Surfaces
Publisher: American Society of Civil Engineers
Abstract: The diffusion of oxygen molecules significantly influence the rate and extent of asphalt’s oxidative aging. This research delves into the dynamic diffusion of oxygen within asphalt, examining the effects of temperature, ...
Characteristics of Urban Waterlogging and Flash Flood Hazards and Their Integrated Preventive Measures: Case Study in Fuzhou, China
Publisher:
Abstract: The frequent extreme weather events have led to dramatic urban waterlogging and flash flood hazards in recent years, which result in heavy casualties and serious economic losses. Mountainous cities like Fuzhou, China, ...
Evaluation of GNSS-IR for Retrieving Soil Moisture and Vegetation Growth Characteristics in Wheat Farmland
Publisher: ASCE
Abstract: Global navigation satellite system interferometric reflectometry (GNSS-IR) is a new remote sensing method that has shown great potential for estimating soil moisture variation and vegetation growth in the vicinity of GNSS ...
Energy Transfer of an Axially Loaded Beam With a Parallel-Coupled Nonlinear Vibration Isolator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Traditional vibration isolation of satellite instruments has an inherent limitation that low-frequency vibration suppression leads to structural instability. This paper explores a parallel-coupled quasi-zero stiffness (QZS) ...
Numerical Analysis of Strain Localization in Granular Soils by Modified Cam-Clay Model Based on Micropolar Continuum Theory
Publisher: American Society of Civil Engineers
Abstract: To predict strain localization behaviors of granular soils, the modified Cam-Clay (MCC) model is incorporated into the second-order cone programming optimized micropolar continuum finite-element method (mpcFEM-SOCP). Based ...
