RISDesign of Underactuated Steerable Electrode Arrays for Optimal Insertions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses the design of wire actuated steerable electrode arrays for optimal insertions in cochlear implant surgery. These underactuated electrode arrays are treated as continuum robots which have an embedded ...
A Real-Time Algorithm for the Correction of Brightband Effects in Radar-Derived QPE
Publisher: American Meteorological Society
Abstract: The bright band (BB) is a layer of enhanced reflectivity due to melting of aggregated snow and ice crystals. The locally high reflectivity causes significant overestimation in radar precipitation estimates if an appropriate ...
A Physically Based Two-Dimensional Seamless Reflectivity Mosaic for Radar QPE in the MRMS System
Publisher: American Meteorological Society
Abstract: he U.S. Weather Surveillance Radar-1988 Doppler (WSR-88D) network has provided meteorologists and hydrologists with quantitative precipitation observations at an unprecedented high spatial?temporal resolution since its ...
Design and Optimization of Seismic Isolation and Damping Devices for Highway Bridges Based on Probabilistic Repair Cost Ratio
Publisher: American Society of Civil Engineers
Abstract: Design of seismic protective devices for highway bridges is often a highly iterative and tedious process due to the nonlinear behavior of the system, a large range of design parameters, and uncertainty of ground motions. ...
Dimensional Estimation of Residual-Drift Demands for Bilinear Bridges under Near-Fault Ground Motions
Publisher: American Society of Civil Engineers
Abstract: Residual drift of bridge columns is an important performance measure for structural damage and postearthquake repair decisions. Yet there are very limited models available for estimating the residual drifts accurately. ...
An Automated 2D Multipass Doppler Radar Velocity Dealiasing Scheme
Publisher: American Meteorological Society
Abstract: An automated 2D multipass velocity dealiasing scheme has been developed to correct velocity fields when wind velocities are very large compared to the Nyquist velocity of the weather Doppler radars. The new velocity ...
Correction of Radar QPE Errors Associated with Low and Partially Observed Brightband Layers
Publisher: American Meteorological Society
Abstract: he melting of aggregated snow/crystals often results in an enhancement of the reflectivity observed by weather radars, and this is commonly referenced as the bright band (BB). The locally high reflectivity often causes ...
Single-Doppler Wind Retrieval in the Moving Frame of Reference
Publisher: American Meteorological Society
Abstract: A single Doppler radar analysis scheme is developed, and three-dimensional wind fields am retrieved from single Doppler radar reflectivity and radial velocity fields. The retrieval is based on two assumptions: 1) the ...
The Role of Vertical Mixing in the Temporal Evolution of Ground-Level Ozone Concentrations
Publisher: American Meteorological Society
Abstract: Aircraft measurements taken during the North American Research Strategy for Tropospheric Ozone-Northeast field study reveal the presence of ozone concentration levels in excess of 80 ppb on a regional scale in the nocturnal ...
Finite Time Coordinated Attitude Control for Spacecraft Formation Flying Under Input Saturation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, finitetime attitude coordinated control for spacecraft formation flying (SFF) subjected to input saturation is investigated. More specifically, a bounded finitetime state feedback control law is first developed ...
