RISThe Influence of Negative Viscosity on Wind-Driven, Barotropic Ocean Circulation in a Subtropical Basin
Publisher: American Meteorological Society
Abstract: In this paper, a new barotropic wind-driven circulation model is proposed to explain the enhanced transport of the western boundary current and the establishment of the recirculation gyre. In this model the harmonic Laplacian ...
Vehicle Weight Limits and Overload Permit Checking Considering the Cumulative Fatigue Damage of Bridges
Publisher: American Society of Civil Engineers
Abstract: The ever-increasing demand in freight transportation results in a fast-growing number of overload permit requests every year. Overweight trucks, if not properly managed, can induce excessive fatigue damage that could ...
The Biomimetic Shark Skin Optimization Design Method for Improving Lubrication Effect of Engineering Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nature has long been an important source of inspiration for mankind to develop artificial ways to mimic the remarkable properties of biological systems. In this work, a new method was explored to fabricate a biomimetic ...
Effects of Pulmonary Fibrosis and Surface Tension on Alveolar Sac Mechanics in Diffuse Alveolar Damage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Diffuse alveolar damage (DAD) is a characteristic histopathologic pattern in most cases of acute respiratory distress syndrome and severe viral pneumonia, such as COVID-19. DAD is characterized by an acute phase with edema, ...
From Scan Strategy to Melt Pool Prediction: A Neighboring-Effect Modeling Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The quality of additive manufacturing (AM) built parts is highly correlated to the melt pool characteristics. Hence, melt pool monitoring and control can potentially improve the AM part quality. This paper presents a ...
Engineering-Guided Deep Learning of Melt-Pool Dynamics for Additive Manufacturing Quality Monitoring
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) fabricates three-dimensional parts via layer-by-layer deposition and solidification of materials. Due to the complexity of this process, advanced sensing is increasingly employed to facilitate ...
