RISA Remote-Sensing Method of Selecting Reference Stations for Evaluating Urbanization Effect on Surface Air Temperature Trends
Publisher: American Meteorological Society
Abstract: n the global lands, the bias of urbanization effects still exits in the surface air temperature series of many city weather stations to a certain extent. Reliable reference climate stations need to be selected for the ...
Latent Pitfalls in Microstructure-Based Modeling for Thermally Aged 9Cr-1Mo-V Steel (Grade 91)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A case study was conducted on a mechanistic model development that predicted tensile strength deterioration with thermal aging of 9Cr-1Mo-V steel in supporting the 60-year design life expected for advanced nuclear reactors. ...
A Simple Absolute Nodal Coordinate Formulation for Thin Beams With Large Deformations and Large Rotations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple but effective formulation of beams with large deformation and large rotation is derived from the principles of continuum mechanics. Proper assumptions are imposed, and the beam strain tensors are formulated from ...
Fast and Robust Full Quadrature Triangular Elements for Thin Plates/Shells With Large Deformations and Large Rotations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new formulation for plates/shells with large deformations and large rotations is derived from the principles of continuum mechanics and calculated using the absolute nodal coordinate formulation (ANCF) techniques. A class ...
Finite-Amplitude Wave-Activity Invariants and Nonlinear Stability Theorems for Shallow Water Semigeostrophic Dynamics
Publisher: American Meteorological Society
Abstract: Motivated by the boundary contributions to the wave-activity invariants and stability theorems of a class of Salmon?s L1-like Hamiltonian balance models, Arnold?s method is applied in this work to derive finite-amplitude ...
Solutions to the 3D Transport Equation and 1D Diffusion Equation for Passive Tracers in the Atmospheric Boundary Layer and Their Applications
Publisher: American Meteorological Society
Abstract: AbstractA solution to the 3D transport equation for passive tracers in the atmospheric boundary layer (ABL), formulated in terms of Green?s function (GF), is derived to show the connection between the concentration and ...
A Retrospective on Dynamic Plasticity and Dynamic Plastic Instability
Publisher: The American Society of Mechanical Engineers (ASME)
Further Results on the Stability of Rapidly Rotating Vortices in the Asymmetric Balance Formulation
Publisher: American Meteorological Society
Abstract: Two kinds of wave-activity invariants, analogous to the pseudomomentum and pseudoenergy densities in the quasigeostrophic theory, are derived for both three-dimensional baroclinic and two-dimensional barotropic asymmetric ...
Optimizing Predictive Maintenance With Machine Learning for Reliability Improvement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Predictive maintenance, as a form of pro-active maintenance, has increasing usage and shows significant superiority over the corrective and preventive maintenance. However, conventional methods of predictive maintenance ...
Path Forward: Materials Data Modernization for ASME Codes and Standards in the Artificial Intelligence Era
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Development of the ASME Materials Properties Database was initiated in the early 2010s to support the ASME Codes and Standards. As information technologies advance at an accelerated pace with the artificial intelligence ...
