RISAccurate Attribution and Seasonal Prediction of Climatic Anomalies Using Causal Inference Theory
Publisher: American Meteorological Society
Abstract: Using features based on correlation or noncausal dependence metrics can lead to false conclusions. However, recent research has shown that applying causal inference theory in conjunction with Bayesian networks to ...
Strengthening Amplitude and Impact of the Pacific Meridional Mode on ENSO in the Warming Climate Depicted by CMIP6 Models
Publisher: American Meteorological Society
Abstract: The Pacific meridional mode (PMM) has been suggested to play an important role in modulating the development of El Niño–Southern Oscillation (ENSO). In this study, we examine the projected changes in the PMM and its impact ...
Study on Wind-Induced Vibration Behavior of Railway Catenary in Spatial Stochastic Wind Field Based on Nonlinear Finite Element Procedure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to its long-span structure and large flexibility, an electrified railway catenary is very sensitive to environmental wind load, especially the time-varying stochastic wind, which may lead to a strong forced vibration ...
Dynamic Response Analysis of a Frame Structure with Superelastic Nitinol SMA Helical Spring Braces for Vibration Reduction
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a new type of energy dissipation brace system that is composed of superelastic Nitinol shape memory alloy (SMA) helical springs to reduce seismic responses of a frame structure. To investigate the ...
Characterizing the Evolution of Groundwater Flow Field and Its Driving Forces in Xi’an, China
Publisher: American Society of Civil Engineers
Abstract: This paper studied the temporal and spatial variation of groundwater levels that characterized the evolution of the groundwater flow field in Xi’an, China, from 1965 to 213, by using the wavelet analysis method. Then under ...
An Experimental Study on Efficient Demulsification for Produced Emulsion in Alkaline/Surfactant/Polymer Flooding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tertiary oil recovery technologies, for example, alkaline/surfactant/polymer (ASP) flooding, can enhance oil recovery as an important oil displacement technology noteworthy in the present oilfields. However, it is the fact ...
Applications of Finite Element Modeling in Biomechanical Analysis of Foot Arch Deformation: A Scoping Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Excessive foot arch deformation is associated with plantar tissue overload and ligamentous injury pathologies. Finite element (FE) analysis, as an effective tool for modeling and simulation, has been utilized clinically ...
Recent Early-Spring Drying Trend over Southern China Associated with Changes in the Zonal Thermal Contrast over the Pacific
Publisher: American Meteorological Society
Abstract: Southern China has experienced a discernible early-spring drying trend in recent decades. This drying trend is a direct result of a severe deficiency of water vapor, which is induced by local descent anomalies and strong ...
Study on the Properties of Titanate Coupling Agent, Modified Heavy Calcium Carbonate, and SBS Composite Modified Asphalt
Publisher: ASCE
Abstract: In this study, heavy calcium carbonate was wet modified using a titanate coupling agent, and fabricated titanate-coupled calcium carbonate and styrene–butadiene–styrene (SBS) were used to prepare composite modified asphalt. ...
Fabrication of an Environmentally Friendly Modifier Based on DAh-MT-MoS2 via Codeposition for the Preparation of Composite TB Rubberized Asphalt
Publisher: American Society of Civil Engineers
Abstract: Adding rubber made from waste tires to asphalt can promote sustainable development of resources on roads. Molybdenum disulfide, as a nanoscale layered solid lubricant, can enhance the compatibility of rubber-modified ...
