RISAnnual Variability of the Subtropical Recirculations in the North Atlantic and North Pacific: A Topex/Poseidon Study
Publisher: American Meteorological Society
Abstract: Using sea surface height data collected by Geosat and Topex/Poseidon, the seasonal (annual) gyre circulations in the regions of the Gulf Stream and the Kuroshio Extension were studied. The seasonal gyre circulation is ...
A Linear Homogeneous Model of Wind-Driven Circulation in a β-Plane Channel
Publisher: American Meteorological Society
Abstract: An analytical solution is sought for a wind-driven circulation in the inviscid limit in a linear barotropic channel model of the Antarctic Circumpolar Ocean in the presence of a bottom ridge. There is a critical height of ...
A Control Strategy of a Two Degrees of Freedom Heavy Duty Parallel Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The motion accuracy of a heavy duty parallel manipulator is usually low due to time lag and the difficulty to realtime measure the position of the endeffector. In this paper, a dynamic modeling of this system with consideration ...
A Measure for Evaluation of Maximum Acceleration of Redundant and Nonredundant Parallel Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper deals with the evaluation of acceleration of redundant and nonredundant parallel manipulators. The dynamic model of three degreesoffreedom (3DOF) parallel manipulator is derived by using the virtual work principle. ...
Annual Rossby Wave in the Southern Indian Ocean: Why Does It “Appear” to Break Down in the Middle Ocean?
Publisher: American Meteorological Society
Abstract: Using both altimetry data (TOPEX/Poseidon and Geosat) and Levitus climatology and a linear reduced-gravity model, the authors studied the annual Rossby waves in the southern Indian Ocean from 19° to 9°S. The most striking ...
Tungsten Nanowire Metamaterials as Selective Solar Thermal Absorbers by Excitation of Magnetic Polaritons
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present study focuses on nanowire-based metamaterials selective solar absorbers. Finite-difference time-domain (FDTD) simulation is employed for numerically designing a broadband solar absorber made of lossy tungsten ...

Annual and Intra-annual Sea Level Variability in the Region of the Kuroshio Extension from TOPEX/POSEIDON and Geosat Altimetry
Publisher: American Meteorological Society
Abstract: Using 4.2 years of sea surface height data collected by the TOPEX/POSEIDON altimeter and 2.3 years of data collected by the Geosat altimeter, the authors study the annual, intra-annual, and linear-trend sea level height ...
Workspace Analysis and Optimal Design of a Translational Cable-Driven Parallel Robot With Passive Springs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cable-driven parallel robots (CDPRs) have great prospects for high-speed applications because of their nature of low inertia and good dynamics. Existing high-speed CDPRs mainly adopt redundant cables to keep positive cable ...
Retrieval of Uniaxial Permittivity and Permeability for the Study of Near-Field Radiative Transport Between Metallic Nanowire Arrays
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently metamaterials made of periodic nanowire arrays, multilayers, and grating structures have been studied for near-field thermal radiation with enhanced coupling of evanescent waves due to surface plasmon/phonon ...
