RISVeering and Strong Coupling Effects in Structural Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mode veering is the phenomenon associated with the eigenvalue loci for a system with a variable parameter: two branches approach each other and then rapidly veer away and diverge instead of crossing. The veering is accompanied ...
A Problem with the Robert–Asselin Time Filter for Three-Time-Level Semi-Implicit Semi-Lagrangian Discretizations
Publisher: American Meteorological Society
Abstract: Three-time-level schemes for first-order differential equations are affected by the existence of computational modes. The Robert?Asselin filter was developed in an Eulerian context to selectively damp such modes while ...
A Review of Virtual Assistants’ Characteristics: Recommendations for Designing an Optimal Human–Machine Cooperation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Designed to improve human–machine interactions, virtual agents and particularly virtual assistants (VAs) are spreading in our daily lives. Presenting a very wide variety of characteristics, studies generally report their ...
A Computer-Aided Design Module to Analyze Manufacturing Configurations of Bent and Hydroformed Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a computer-aided design (CAD) module able to analyze different manufacturing configurations of tubes used in mechanical assemblies, such as exhaust system manifolds. It can ...
Turbulence Closure Parameterization and Grid Spacing Effects in Simulated Supercell Storms
Publisher: American Meteorological Society
Abstract: Many meteorological organizations plan to substantially increase the resolution of the limited-area models used for severe weather prediction. Such an approach does not guarantee a priori the reduction of the uncertainty ...
Large-Scale Atmospheric Warming in Winter and the Arctic Sea Ice Retreat
Publisher: American Meteorological Society
Abstract: he ongoing shrinkage of the Arctic sea ice cover is likely linked to the global temperature rise, the pronounced warming in the Arctic, and possibly weather anomalies in the midlatitudes. By evaluating independent components ...
Rheological Percolation Threshold in High-Viscosity Polymer/CNTs Nanocomposites
Publisher: American Society of Civil Engineers
Abstract: Polystyrene (PS)/multi-walled carbon nanotubes (CNT) nanocomposites have been prepared through melt mixing processing aiming at obtaining a uniform and homogeneous dispersion of the used nanoparticles within the polymeric ...
Thermomechanical Effects Induced by Energy Piles Operation in a Small Piled Raft
Publisher: American Society of Civil Engineers
Abstract: In this work, a series of fully coupled three-dimensional thermomechanical finite-element analyses has been carried out to investigate the mechanical and thermal interaction effects induced in a small piled raft equipped ...
Rheological Percolation Threshold in High-Viscosity Polymer/CNTs Nanocomposites
Publisher: American Society of Civil Engineers
Abstract: Polystyrene (PS)/multi-walled carbon nanotubes (CNT) nanocomposites have been prepared through melt mixing processing aiming at obtaining a uniform and homogeneous dispersion of the used nanoparticles within the polymeric ...
Emission-Induced Nonlinearities in the Global Aerosol System: Results from the ECHAM5-HAM Aerosol-Climate Model
Publisher: American Meteorological Society
Abstract: In a series of simulations with the global ECHAM5-HAM aerosol-climate model, the response to changes in anthropogenic emissions is analyzed. Traditionally, additivity is assumed in the assessment of the aerosol climate ...
