RISAn Investigation of Key Design for Additive Manufacturing Constraints in Multimaterial Three Dimensional Printing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The PolyJet material jetting process is uniquely qualified to create complex, multimaterial structures. However, key manufacturing constraints need to be explored and understood in order to guide designers in their use of ...
Principal Component Analysis of Wind Profiler Observations
Publisher: American Meteorological Society
Abstract: Principal component analysis (PCA) is applied to wind profiler observations to study the vertical profile of the wind field and its temporal evolution. The rationale for decomposing time?height wind profiler data using PCA ...
Vertical Air Motion Retrieved from Dual-Frequency Profiler Observations
Publisher: American Meteorological Society
Abstract: he 50-MHz profiler operating near Darwin, Northwest Territory, Australia, is sensitive to both turbulent clear-air (Bragg) and hydrometeor (Rayleigh) scattering processes. Below the radar bright band, the two scattering ...
The Accuracy of Radar Estimates of Ice Terminal Fall Speed from Vertically Pointing Doppler Radar Measurements
Publisher: American Meteorological Society
Abstract: oppler radar measurements at different frequencies (50 and 2835 MHz) are used to characterize the terminal fall speed of hydrometeors and the vertical air motion in tropical ice clouds and to evaluate statistical methods ...
The Anatomy of a Continental Tropical Convective Storm
Publisher: American Meteorological Society
Abstract: This study provides a very clear picture of the microphysics and flow field in a convective storm in the Rondonia region of Brazil through a synthesis of observations from two unique radars, measurements of the surface ...
Uncertainties in Profiler and Polarimetric DSD Estimates and Their Relation to Rainfall Uncertainties
Publisher: American Meteorological Society
Abstract: Polarimetric weather radars offer the promise of accurate rainfall measurements by including polarimetric measurements in rainfall estimation algorithms. Questions still remain on how accurately polarimetric measurements ...
Effect of Particle Size Distribution on Powder Packing and Sintering in Binder Jetting Additive Manufacturing of Metals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The binder jetting additive manufacturing (AM) process provides an economical and scalable means of fabricating complex parts from a wide variety of materials. While it is often used to fabricate metal parts, it is typically ...
Investigation of Parameter Spaces for Topology Optimization With Three-Dimensional Orientation Fields for Multi-Axis Additive Manufacturing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The layer-by-layer deposition process used in material extrusion (ME) additive manufacturing results in inter- and intra-layer bonds that reduce the mechanical performance of printed parts. Multi-axis (MA) ME techniques ...
An Intercomparison of Model Simulations and VPR Estimates of the Vertical Structure of Warm Stratiform Rainfall during TWP-ICE
Publisher: American Meteorological Society
Abstract: A model of rain shaft microphysics that solves the stochastic advection?coalescence?breakup equation in an atmospheric column was used to simulate the evolution of a stratiform rainfall event during the Tropical Warm ...
Statistics of Storm Updraft Velocities from TWP-ICE Including Verification with Profiling Measurements
Publisher: American Meteorological Society
Abstract: omparisons between direct measurements and modeled values of vertical air motions in precipitating systems are complicated by differences in temporal and spatial scales. On one hand, vertically profiling radars more directly ...
