RISAn Eigenfrequency Analysis of Mixed Rossby–Gravity Waves on Barotropic Vortices
Publisher: American Meteorological Society
Abstract: n this study, the linearized, f-plane, shallow-water equations are discretized into a matrix eigenvalue problem to examine the full spectrum of free waves on barotropic (monopolar and hollow) vortices. A typical wave ...
A Theory for Mixed Vortex Rossby–Gravity Waves in Tropical Cyclones
Publisher: American Meteorological Society
Abstract: Vortex?Rossby waves (VRWs) and inertial gravity waves (IGWs) have been proposed to explain the propagation of spiral rainbands and the development of dynamical instability in tropical cyclones (TCs). In this study, a theory ...
Experimental and Analytical Evaluation of Steel Frame Collapse Resistance with Corrugated Web H-Beams under an Internal Column Removal Scenario
Publisher: American Society of Civil Engineers
Abstract: AbstractH-shaped steel beams with corrugated webs (CWs) have been applied extensively in the
construction industry for various structural applications owing to their distinctive
advantages. However, their anticollapse ...
Experimental Study of Pressure Drop Flow Rate Characteristics of Heated Tight Porous Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tight porous materials are used as pneumatic components in a wide range of industrial applications. Such porous materials contain thousands of interconnected irregular micropores, which produce a large pressure drop (خ”P) ...
Attacking Satellite Path Planning Based on Genetic Algorithm
Publisher: American Society of Civil Engineers
Abstract: In the space attack defensive system, a satellite is usually used to attack another satellite. To approach the target satellite successfully, path planning is very important for the attacking satellite, especially when the ...
Wear of Carbon Nanofiber Reinforced HDPE Nanocomposites Under Dry Sliding Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High density polyethylene (HDPE) is widely used as a bearing material in industrial application because of its low friction and high wear resistance properties. Carbon nanofiber (CNF) reinforced HDPE nanocomposites are ...
Experimental and Theoretical Study on Nonlinear Behavior of Compression-Mode Viscoelastic Dampers under Different Excitations and Temperatures
Publisher: ASCE
Abstract: This work designs a new compression-mode viscoelastic (VE) damper to avoid bonding interface failure in classical shear-mode VE dampers. However, most existing mathematical models based on the shear deformation at the ...
A Study on Urban Heating System Flexibility: Modeling and Evaluation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the urban heating system (UHS) by taking a look at the heat transportation flexibility of the system. We propose the heating system flexibility (HSF) concept to represent UHS’s capability of meeting ...
Experimental and Numerical Studies of a Novel Multidimensional Isolation and Mitigation Device for Precast Wall Panel Systems
