RISDecomposition of the Hierarchical Variability of Concrete Random Fields and Its Influence on the Hysteretic Behavior of Structural Components
Publisher: American Society of Civil Engineers
Abstract: Due to factors like heterogeneity, curing conditions, and production processes, concrete in structures exhibits hierarchical variability and spatial correlation. However, in engineering practice, when considering the ...
Chloride Transport in an Aggregated Clay Soil Column
Publisher: American Society of Civil Engineers
Abstract: Soil aggregates as the basic units of soil structure greatly affect soil properties and fertilizer. They have an important theoretical and practical significance in studying the change in solute transport with different ...
Uncertainty and Disturbance Estimator-Based Backstepping Control for Nonlinear Systems With Mismatched Uncertainties and Disturbances
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes an uncertainty and disturbance estimator (UDE)-based controller for nonlinear systems with mismatched uncertainties and disturbances, integrating the UDE-based control and the conventional backstepping ...
Effect of Superabsorbent Polymer on the Rheological Behavior and Structural Evolution of Alkali-Activated Slag
Publisher: American Society of Civil Engineers
Abstract: Utilizing superabsorbent polymers (SAP) in alkali activated slag (AAS) can promote internal curing and remarkably alleviate the shrinkage of AAS. This promising additive has attracted considerable attention for its potential ...

A New Numerical Method for Solving Nonlinear Fractional Fokker–Planck Differential Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear fractional-order Fokker–Planck differential equations have been used in many physical transport problems which take place under the influence of an external force filed. Therefore, high-accuracy numerical ...
Water-Circulating Aerator: Optimizing Structure and Predicting Water Flow Rate and Oxygen Transfer
Publisher: American Society of Civil Engineers
Abstract: Thermal stratification is a common phenomenon in deep lakes and reservoirs, which often results in water-quality deterioration, including such problems as hypolimnetic anoxia, the release of pollutants from sediments, and ...
