RISWeakly or Strongly Nonlinear Mesoscale Dynamics Close to the Tropopause?
Publisher: American Meteorological Society
Abstract: AbstractRecently, it has been discussed whether the mesoscale energy spectra in the upper troposphere and lower stratosphere are generated by weakly or strongly nonlinear dynamics. A necessary condition for weak nonlinearity ...
Fretting Wear Behavior of Micro-Arc Oxidation Coating Fabricated on AZ91 Magnesium Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the effect mechanisms between the fretting wear behavior and properties of micro-arc oxidation (MAO) coatings fabricated by different anodic voltages (AVs) on AZ91 magnesium alloy were investigated. The ...
A Novel Probe Based on Photoconductive Effect for Non-Destructive Testing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research is primarily motivated by the demand for a convenient and economical nondestructive testing solution in industrial scenarios. We present a novel nondestructive testing probe, which is ingeniously designed ...
Simulation of Torsionally Loaded Deep Foundations Considering State-Dependent Load Transfer
Publisher: American Society of Civil Engineers
Abstract: Deep foundations may need to resist torsional loads, resulting from wind loading on traffic sign and signal pole structures, or seismic loading on curved or skewed bridges. Although design methods for deep foundations at ...
The Generation and Evolution of Nonlinear Internal Waves in the Deep Basin of the South China Sea
Publisher: American Meteorological Society
Abstract: ime series observations of nonlinear internal waves in the deep basin of the South China Sea are used to evaluate mechanisms for their generation and evolution. Internal tides are generated by tidal currents over ridges ...
Tunable Negative Refractive Index Metamaterials Based on Thermochromic Oxides
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A tunable metamaterial is proposed by combining a thermochromic oxide with a fishnet structure. The reflection and transmission coefficients are calculated by finitedifference timedomain (FDTD) method. The effective ...
Model-Selection Uncertainty Quantifications in HFFB Dynamic Analyses of a Complex Tall Building
Publisher: American Society of Civil Engineers
Abstract: The high-frequency force balance (HFFB) technique is widely adopted for the assessment of wind loads acting on a tall building because of its simplicity and versatility. Although a number of HFFB-based analysis methods ...
Effects of Wave–Current Interactions on Bay–Shelf Exchange

On Internal Waves Propagating across a Geostrophic Front
Publisher: American Meteorological Society
Abstract: AbstractReflection and transmission of normally incident internal waves propagating across a geostrophic front, like the Kuroshio or Gulf Stream, are investigated using a modified linear internal wave equation. A transformation ...
Anomalous Enhancement of Heat Transfer to H2O/CO2 Mixtures in Near-Critical Region
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat transfer to supercritical H2O/CO2 mixtures (24 MPa, 310 to 430 °C, and CO2 mass fractions up to 18.5%), the working fluids of a novel power generation system with coal gasified in supercritical water, was experimentally ...
