RISA Monte Carlo Background Covariance Localization Method for an Ensemble–Variational Assimilation System
Publisher: American Meteorological Society
Abstract: AbstractSpurious long-distance correlations in estimates of the background error covariance can deteriorate the performance of ensemble-based data assimilation methods. In this study, a localization method, called Monte ...
On the Measurement of Heat Waves
Publisher: American Meteorological Society
Abstract: espite their adverse impacts, definitions and measurements of heat waves are ambiguous and inconsistent, generally being endemic to only the group affected, or the respective study reporting the analysis. The present study ...
Impact, Fire, and Fluid Spread Code Coupling for Complex Transportation Accident Environment Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Transportation accidents frequently involve liquids dispersing in the atmosphere. An example is that of aircraft impacts, which often result in spreading fuel and a subsequent fire. Predicting ...
Damage Tolerance and Assessment of Foam-Inflated Aerospace Structures
Publisher: American Society of Civil Engineers
Abstract: Design and operational issues with respect to the use of inflatable-deployable foam-rigidized components in aerospace structures are investigated in this paper. The sample structures used in this study are fabricated from ...
Asymptotic Homogenization of Composite Materials and Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper provides details on the new trends in application of asymptotic homogenization techniques to the analysis of composite materials and thin-walled composite structures and their ...
Battery Less Wireless Instrumented Knee Implant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Over 400,000 total knee replacement procedures (TKR) are performed annually in the United States. This paper focuses on the development of a batteryless wireless instrumented tibial tray for performance feedback in TKR ...
Curvature Sensitive Modification of Pure Pursuit Control1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pure pursuit control is a commonly used method in the vehicle path-tracking problem. While widely used, it has some limitations, including the fact that its accuracy is very sensitive to the lookahead distance. A variety ...

Three Dimensional Mass Fraction Distribution of a Spray Measured by X Ray Computed Tomography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to design a spraying system with the desired characteristics, the atomization process has to be understood in detail, including the primary breakup of the liquid core. Accurate prediction of primary breakup is a ...
A Noninterpolated Estimate of Horizontal Spatial Covariance from Nonorthogonally and Irregularly Sampled Scalar Velocities
Publisher: American Meteorological Society
Abstract: AbstractThis paper presents a least squares method to estimate the horizontal (isotropic or anisotropic) spatial covariance of two-dimensional orthogonal vector components, without introducing an intervening mapping step ...
