RISGrammar-Based Designer Assistance Tool for Epicyclic Gear Trains
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a grammar-based designer assistance tool for Epicyclic Gear Trains (EGTs) that helps designers generate concepts of EGT structures during conceptual design. The tool is comprised ...
Evaluation of Three Weight Functions for Nonlocal Regularization of Sand Models
Publisher: American Society of Civil Engineers
Abstract: Nonlocal regularization is frequently used to resolve the mesh dependency issue that is caused by strain softening in finite-element (FE) simulations. Some or all variables that affect strain softening are assumed to depend ...
Reliability of High-Power Light Emitting Diode Attached With Different Thermal Interface Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As a solid electroluminescent source, white light emitting diode (LED) has entered a practical stage and become an alternative to replace incandescent and fluorescent light sources. However, due ...
Stabilization Effect of Anionic Polyacrylamide on Marine Clay Treated with Lime
Publisher: ASCE
Abstract: Marine clays often need improvements before construction and how to stabilize such kind of soft soil has been a great challenge. To address this issue, a newly proposed additive, which is named anionic polyacrylamide (APAM), ...
Understanding Public Acceptability of Congestion Charging in Beijing
Publisher: ASCE
Abstract: Beijing, the capital city of China, currently experiences serious traffic congestion and extreme air pollution. To mitigate these issues, Beijing Municipality is currently considering implementing a congestion charging ...
Approach for Water Distribution System Model Calibration Based on Iterative Sherman–Morrison Formula
Publisher: ASCE
Abstract: Real-time modeling of water distribution systems (WDSs) has received much attention in WDS operation and management. As the model input, nodal water demand must be calibrated in a timely manner. However, for the large-scale ...
Characteristic Differences of CrIS All-Sky Simulations of Brightness Temperature with Different Microphysics Parameterization Schemes
Publisher: American Meteorological Society
Abstract: Influences of cloud liquid water, cloud ice, rain, snow, and graupel on all-sky simulations of the Cross-track Infrared Sounder (CrIS) brightness temperature (TB) are assessed for the 399 data assimilation (DA) channels. ...
Mechanical Properties of Three-Dimensional Printed Combination-Design Truss Lattice Materials: Static and Dynamic Loading
Publisher: ASCE
Abstract: In this paper, four types of truss lattices are designed by combining octet truss (FCC) unit cells with other elementary unit cells, including Simple Cubic (SC), Body-centered Cubic (BCC), Body-centered Block (BCB), and ...
A Simplified Calculation Method for the Shear Strength of Unsaturated Silt
Publisher: American Society of Civil Engineers
Abstract: The matric suction must be measured when calculating the shear strength of unsaturated silt, but the measurement method is cumbersome and time-consuming. The saturation degree of silt is easily measured; therefore, a ...
Preparation and Properties of Self-Healing Polyurethane-Modified Asphalt Composed of Different Soft Segments
Publisher: American Society of Civil Engineers
Abstract: When asphalt pavement is in practical use, it is prone to cracking and other diseases due to the long-term effects of load and climate and the restricted self-healing properties of the asphalt material. In order to improve ...
