RISThe Coupling of the Annual Cycle and ENSO Over the Tropical Pacific
Publisher: American Meteorological Society
Abstract: In the tropical Pacific, the annual variation of sea surface temperature (SST) consists of two distinct components with respect to the equator, 1) an antisymmetric extratropical annual cycle and 2) a symmetric equatorial ...
Tide-Induced Sediment Resuspension and the Bottom Boundary Layer in an Idealized Estuary with a Muddy Bed
Publisher: American Meteorological Society
Abstract: Sediment transport and bottom boundary layer (BBL) in an idealized estuary with a muddy bed were studied by numerical simulations. The focus was placed on description and prediction of the dynamics of nepheloid layer (a ...
Hydrodynamic Characteristics of Bridge Cofferdam Under Multidirectional Focused Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the process of coastal bridge construction, cofferdams become necessary facilities to ensure the construction environment is dry and safe. However, during the construction period of coastal bridges, extreme surges and ...
Dynamic Analysis of an Automotive Belt-Drive System With a Noncircular Sprocket by a Modified Incremental Harmonic Balance Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dynamic model of an automotive belt-drive system with a noncircular sprocket instead of a round sprocket is developed in this work to study the effect of reducing the angular variation of camshafts. There are two submodels ...
Design, Modeling, and Experimental Validation of a Novel Infinitely Variable Transmission Based on Scotch Yoke Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel infinitely variable transmission (IVT) based on scotch yoke systems is designed to provide a continuously varied outputtoinput speed ratio from zero to a specified value. By changing the crank length of scotch yoke ...
Modeling and Control of an Infinitely Variable Speed Converter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Traditional transmission in a vehicle has low efficiency and that in a wind turbine has a constant outputtoinput speed ratio, which needs a power converter to regulate the current frequency that can be fed into the grid. ...
A New Spatial and Temporal Harmonic Balance Method for Obtaining Periodic Steady-State Responses of a One-Dimensional Second-Order Continuous System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new spatial and temporal harmonic balance (STHB) method is developed for obtaining periodic steady-state responses of a one-dimensional second-order continuous system. The spatial harmonic balance procedure with a series ...
Design, Modeling, and Simulation of a Geared Infinitely Variable Transmission
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An infinitely variable transmission (IVT) to provide a continuous outputtoinput speed ratio from zero to a certain value is designed, and its working principle is illustrated. It is a geared IVT (GIVT), since its function ...
Design and Stability Analysis of an Integral Time-Delay Feedback Control Combined With an Open-Loop Control for an Infinitely Variable Transmission System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The kinematic model of an infinitely variable transmission (IVT) is introduced, and the nonlinear differential equation for the dynamic model of the IVT system with a permanent magnetic direct current (DC) motor and a ...
Sensitivity of the Systematic Error of Extended Range Forecasts to Sea Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: The sensitivity of the systematic error of extended-range forecasts to sea surface temperature (SST) anomalies is investigated. General circulation model (GCM) experiments were performed to quantify error patterns for warm, ...
