RISSensitivity of Numerical Simulations of Near-Surface Atmospheric Conditions to Snow Depth and Surface Albedo during an Ice Fog Event over Heber Valley
Publisher: American Meteorological Society
Abstract: AbstractThis study examines the sensitivity of numerical simulations of near-surface atmospheric conditions to the initial surface albedo and snow depth during an observed ice fog event in the Heber Valley of northern Utah. ...
Numerical Simulation of Rapid Weakening of Hurricane Joaquin with Assimilation of High-Definition Sounding System Dropsondes during the Tropical Cyclone Intensity Experiment: Comparison of Three- and Four-Dimensional Ensemble–Variational Data Assimilation
Publisher: American Meteorological Society
Abstract: AbstractObservations from High-Definition Sounding System (HDSS) dropsondes, collected for Hurricane Joaquin during the Office of Naval Research Tropical Cyclone Intensity (TCI) field experiment in 2015, are assimilated ...
Crystal Plasticity Analysis of Stress Partitioning Mechanisms and Their Microstructural Dependence in Advanced Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Twophase advanced steels have an optimized combination of high yield strength and large elongation strain at failure, as a result of stress partitioning between a hard phase (martensite) and a ductile phase (ferrite or ...
An Analytical Model for Thermoelastic Damping in Microresonators Based on Entropy Generation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an analytical model for thermoelastic damping (TED) in micromechanical resonators, which is based on entropy generation, a thermodynamic parameter measuring the irreversibility in heat conduction. The ...
Effects of Vertical Eddy Diffusivity Parameterization on the Evolution of Landfalling Hurricanes
Publisher: American Meteorological Society
Abstract: ue to rapid changes in surface conditions when a landfalling hurricane moves from ocean to land, interactions between the hurricane and surface heat and moisture fluxes become essential components of its evolution and ...
Solving Differential Algebraic Equation Systems: Alternative Index 2 and Index 1 Approaches for Constrained Mechanical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Regarding constrained mechanical systems, we are faced with index3 differentialalgebraic equation (DAE) systems. Direct discretization of the index3 DAE systems only enforces the position constraints to be fulfilled at the ...
The Notch-Bend Strength of Titanium, Aluminum, and Copper-Base Alloys in Heavy Sections
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The notch-bend strength of four titanium, eight aluminum, and eight copper-base alloys was measured. Specimen sizes ranged from 0.4 to 4 in. in section thickness. All materials showed a geometrical ...
Priority-Based Geometric Constraint Satisfaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A well-constrained geometric system seldom occurs in practice, especially at the sketch-based initial conceptual design stage. Usually, it is either under- or overconstrained because design is a ...
Testing and Modeling of Soil-Structure Interface
Publisher: American Society of Civil Engineers
Abstract: An accurate modeling of soil-structure interfaces is very important in order to obtain realistic solutions of many soil-structure interaction problems. To study the mechanical characteristics of soil-structure interface, ...
Application of ANN-Based Response Surface Method to Prediction of Ultimate Strength of Stiffened Panels
Publisher: American Society of Civil Engineers
Abstract: the existing experimental data. The key issues in optimizing an ANN model are systematically examined. The developed formula is compared with some existing analytical formulas, such as Faulkner’s formulas, Pu’s formulas, and Carlsen’s formula. It is determined...
