RISRandomized Neural Networks with Petrov–Galerkin Methods for Solving Linear Elasticity and Navier–Stokes Equations
Publisher: ASCE
Abstract: We develop randomized neural networks (RNNs) with Petrov–Galerkin (RNN-PG) methods to solve linear elasticity and Navier–Stokes equations. RNN-PGs use the Petrov–Galerkin variational framework, where the solution is ...
Roles of the Moisture and Wave Feedbacks in Shaping the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: AbstractThis study investigates the moisture and wave feedbacks in the Madden?Julian oscillation (MJO) dynamics by applying the general three-way interaction theoretical model. The three-way interaction model can reproduce ...
Pattern of Wintertime Southern Rainfall and Northern Pollution over Eastern China: The Role of the Strong Eastern Pacific El Niño
Publisher: American Meteorological Society
Abstract: Air quality over the North China Plain (NCP) and rainfall over southern China exhibit robust and correlated interannual variations during winter from 1979 to 2018. A correlation coefficient of 0.7 between the PM
DEM Analysis of Stresses and Deformations of Geogrid-Reinforced Embankments over Piles
Publisher: American Society of Civil Engineers
Abstract: The geosynthetic-reinforced pile-supported embankment is one of the favorable ground improvement techniques used in the construction of earth structures over a compressible soil when limited construction time is available ...
New Global Sensitivity Measure Based on Fuzzy Distance
Publisher: American Society of Civil Engineers
Abstract: In this paper, a new fuzzy distance index is proposed to measure the effect of the fuzzy distribution parameters of random model inputs on the statistical characteristics of model output. First, the definition of the ...
Thermal-Fatigue Analysis of District-Heating Pipelines in China
Publisher: ASCE
Abstract: The temperature variation of the district heating (DH) pipelines during the operation is the most severe threat to the lifetime of the systems. The number of cycles used in the fatigue analysis in the European standard ...
Mechanical-Based Approach for Operational Risk Evaluation of Water Mains in Shanghai
Publisher: ASCE
Abstract: A mechanical-based approach was applied in this study to evaluate the operational risk of water mains in the Shanghai region. First, a pipeline’s structural performance in terms of stress indicators and structural failure ...
Conventional, Thermal, and Rheological Properties of Asphalt Binder Modified by Carbon Nanotubes and Crumb Rubber
Publisher: ASCE
Abstract: The purpose of this paper was to investigate the effect of carbon nanotubes (CNTs) and crumb rubber (CR) on the conventional properties, thermal behaviors, and rheological properties of binders. There are four asphalt types ...
Estimating Maximum Bending Moment in High-Density Polyethylene Pipes under Traffic Loading
Publisher: ASCE
Abstract: High-density polyethylene (HDPE) pipes have been widely adopted for municipal pipeline projects all over the world. HDPE pipe failures, including reduced flow capacity and wall buckling, have been reported extensively, and ...
Modified Waterborne Epoxy as a Cold Pavement Binder: Preparation and Long-Term Working Properties
Publisher: ASCE
Abstract: The purpose is to enhance the working properties of waterborne epoxy resin and improve the quality of cold pavement binder usage. In this study, a modified waterborne polyurethane/epoxy composite was prepared. The influence ...
