Three-Dimensional Mathematical Model of Suspended-Sediment Transport
Publisher: American Society of Civil Engineers
Abstract: This paper presents the basic equations for a mathematical model of sediment-laden flow in a nonorthogonal curvilinear coordinate system. The equations were derived using a tensor analysis of two-phase flow and incorporate ...
Stabilization of Heavy Metals in Contaminated River Sediment by Nanozero-Valent Iron/Activated Carbon Composite
Publisher: American Society of Civil Engineers
Abstract: Nanozero-valent iron/activated carbon (nZVI/AC) composite is investigated as a possible stabilization agent for heavy metals in river sediment. Effects of stabilization were tested by leaching tests such as synthetic ...
Particle Swarm Optimization of Aerodynamic Shapes with Nonuniform Shape Parameter–Based Radial Basis Function
Publisher: American Society of Civil Engineers
Abstract: Efficient global optimization of aerodynamic shapes with the high-fidelity method is of great importance in the design process of modern aircrafts. In this study, modifications are made to the particle swarm optimization ...
An Information Fusion Model Based on Dempster–Shafer Evidence Theory for Equipment Diagnosis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An abnormal operating effect can be caused by different faults, and a fault can cause different abnormal effects. An information fusion model, with hybrid-type fusion frame, is built in this paper, so as to solve this ...
Development of Attention-Based Bidirectional Long Short-Term Memory Networks for Earthquake Prediction in Taiwan
Publisher: American Society of Civil Engineers
Abstract: Located at a tectonic boundary, Taiwan is highly prone to severe earthquakes that often cause significant loss of life and economic damage, underscoring the need for improved prediction methods. While traditional approaches ...
Comparative Study of Cationic Surfactant CTAC Tailoring
Publisher: American Society of Civil Engineers
Abstract: Cationic surfactant cetyltrimethylammonium chloride (CTAC) was employed to tailor-activated carbon, granular ferric hydroxide (GFH), chitosan, zeolite, and bentonite so as to investigate the effect of CTAC tailoring on ...
Variational-Based Data Assimilation to Simulate Sediment Concentration in the Lower Yellow River, China
