RISProperties of the Threshold Method on a Radar Rain Cluster Basis
Publisher: American Meteorological Society
Abstract: The average rain rate ?R? is estimated with radar data at the radar beam height by measuring the fractional area F(τ) of pixels above a preset rain-rate threshold τ. This work applies the ?threshold method? to smaller ...
Understanding the Effect of Heat Input and Sheet Gap on Porosity Formation in Fillet Edge and Flange Couch Laser Welding of AC 170PX Aluminum Alloy for Automotive Component Manufacture
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An investigation is reported on the characteristics of porosity formation in high power disk laser welding of AC170PX (AA6014) alloy sheets (coated with titanium and zirconium) in two weld joint configurations: fillet edge ...
Discussion: “A Sixth Order Theory of Shear Deformable Beams With Variational Consistent Boundary Conditions†(Shi, G., and Voyiadjis, G. Z., 2011, ASME J. Appl. Mech., 78(021019), pp. 1–11)

Nowcasting of Motion and Growth of Precipitation with Radar over a Complex Orography
Publisher: American Meteorological Society
Abstract: Motion vectors of radar echo patterns can be obtained by applying a cross-correlation method (e.g., the TREC method) to radar data collected several minutes apart Here an extension of TREC, called COTREC, is presented. ...
Dispersion Error Reduction for Acoustic Problems Using the Finite Element Least Square Point Interpolation Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The shape function of the finite elementleast square point interpolation method (FELSPIM) combines the quadrilateral element for partition of unity and the least square point interpolation method (LSPIM) for local ...
Relation between Large-Scale Circulation and European Winter Temperature: Does It Hold under Warmer Climate?
Publisher: American Meteorological Society
Abstract: The idea of using large-scale information to predict local climate variability is widely exploited in climate change impact studies as an alternative to computationally expensive high-resolution models. This approach implies ...
A Surface Reference Technique for Airborne Doppler Radar Measurements in Hurricanes
Publisher: American Meteorological Society
Abstract: The operational algorithm for rainfall retrieval from the Tropical Rainfall Measuring Mission (TRMM) precipitation radar data requires a measurement of the path-integrated attenuation (PIA) as a constraint. This constraint ...
Comparison of TRMM Precipitation Radar and Airborne Radar Data
Publisher: American Meteorological Society
Abstract: The first spaceborne weather radar is the precipitation radar (PR) on the Tropical Rainfall Measuring Mission (TRMM), which was launched in 1997. As part of the TRMM calibration and validation effort, an airborne rain-mapping ...
Coupled Computational Fluid Dynamic and Finite Element Multiphase Modeling of Laser Weld Bead Geometry Formation and Joint Strengths
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser welding is used extensively in industry for joining various materials in the assembly of components and structures. Localized melting followed by rapid cooling results in the formation of a weld bead and generation ...
On the Performance of Wavy Dry Friction and Piezoelectric Hybrid Flexible Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a flexible dry friction plate to mitigate the vibration of thin-walled structures for one resonance crossing. Based on a cantilever beam–friction damper finite element model, the geometry and material ...
