RISIncorporating Hydromechanical Coupling of Unsaturated Soils into the Analysis of Rainwater-Induced Groundwater Ponding
Publisher: American Society of Civil Engineers
Abstract: The moisture contents and coefficients of permeability of partially saturated soils are assumed to follow an exponential function of the pressure head. A partial differential equation is proposed here to describe the ...
Precision Forming of the Straight Edge of Square Section by Die-Less Spinning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Die-less spinning is a forming process to achieve cone shape parts. It is suitable for small batch production because of low costs and short development cycle. In order to increase the forming accuracy of the square section ...
A Novel Global Optimization Algorithm and Its Application to Airfoil Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a novel global optimization algorithm has been developed, which is named as particle swarm optimization combined with particle generator (PSO–PG). In PSO–PG, a PG was introduced to iteratively generate ...
Emulating Spatial and Temporal Outputs From Fuel Cell and Battery Models: A Comparison of Deep Learning and Gaussian Process Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Neural network models have a long history in fuel cell and battery modeling. With the recent advent of deep learning, there is potential for further improvements in these models. Conversely, deep learning is primarily ...
Weldability and Distortion of Mg AZ31-to-Galvanized Steel SPOT Plug Welding Joint by Cold Metal Transfer Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, cold metal transfer (CMT) plug welding of 1 mm thick Mg AZ31 to 1 mm thick hot-dipped galvanized mild steel (i.e., Q235) was studied. Welding tests were performed and the process variables optimized with Mg ...
