RISThe Role of Oceanic Feedback in the Climate Response to Doubling CO2
Publisher: American Meteorological Society
Abstract: wo suites of partial coupling experiments are devised with the upper-ocean dynamics version (UOM) of the CCSM3 to isolate the effects of the feedbacks from the change of the wind-driven ocean circulation and air?sea heat ...
Design of a Lightweight Single-Actuator Multi-Grasp Prosthetic Hand With Force Magnification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Restoring human grasp functions by prosthesis is a long-standing challenge in robotics research. Aiming at prosthetic applications, this paper presents a novel anthropomorphic multi-grasp hand design. The hand is driven ...
Spherical Elastic–Plastic Contact Model for Power-Law Hardening Materials Under Combined Normal and Tangential Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The contact between a power-law hardening elastic–plastic sphere and a rigid flat under combined normal and tangential loads in full stick is studied in this work. The displacement-driven loading is used since the frictional ...
On the Singularity Theory Applied in Rail Vehicle Bifurcation Problem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The application of Hopf bifurcation is essential to rail vehicle dynamics because it corresponds to the linear critical speed. In engineering, researchers always wonder which vehicle parameters are sensitive to it. With ...
Numerical Analysis of Transient Elastohydrodynamic Lubrication During Startup and Shutdown Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a numerical model is developed for the analysis of elastohydrodynamic lubrication (EHL) at transient conditions during startup and shutdown processes. The time-dependent solutions are derived from an iterative ...
A Numerical Investigation of Mixed Thermal Elastohydrodynamic Lubrication in Tilting-Pad Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tilting-pad journal bearing in the cooling system of the nuclear power plant is equipped below the ground and vertically positioned to accomplish its function for water transfer. Usually, the loading conditions are ...
Design and Analysis of a Swashplate Control System for an Asymmetric Axial Piston Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the previously developed fixed-displacement asymmetric axial piston pump, a variable displacement asymmetric axial piston pump (VDAAPP) with three independent suction/delivery ports is proposed. A basic linear ...
Evaluation of the Surface Representation of the Greenland Ice Sheet in a General Circulation Model
Publisher: American Meteorological Society
Abstract: imulated surface conditions of the Goddard Earth Observing System model, version 5 (GEOS-5), atmospheric general circulation model (AGCM) are examined for the contemporary Greenland Ice Sheet (GrIS). A surface parameterization ...
The Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2)
Publisher: American Meteorological Society
Abstract: AbstractThe Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), is the latest atmospheric reanalysis of the modern satellite era produced by NASA?s Global Modeling and Assimilation Office ...
