RISEffect of Solder Joint Thickness on Intermetallic Compound Growth Rate of Cu/Sn/Cu Solder Joints During Thermal Aging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sandwich structure Cu/Sn/Cu solder joints with different thicknesses of the solder layers (δ) are fabricated using a reflow solder method. The microstructure and composition of the solder joints are observed and analyzed ...
Discrete-Element Method Study of the Effect of Ballast Layer Depth on the Performance of Railway Ballast Bed
Publisher: American Society of Civil Engineers
Abstract: In the construction and maintenance of railway track systems, studying the influence of ballast depth on the performance of railway track structures is important to ensure the safety and sustainability of the built ...
Interaction between the MJO and High-Frequency Waves over the Maritime Continent in Boreal Winter
Publisher: American Meteorological Society
Abstract: AbstractThe two-way interaction between Madden?Julian oscillation (MJO) and higher-frequency waves (HFW) over the Maritime Continent (MC) during boreal winter of 1984?2005 is investigated. It is noted from observational ...
Further Development of the Regional Boundary Layer Model to Study the Impacts of Greenery on the Urban Thermal Environment
Publisher: American Meteorological Society
Abstract: forest canopy model is developed and coupled into the Regional Boundary Layer Model (RBLM) to fully consider the vertical structure of tree morphology. Instead of a slab surface model formerly used to represent trees in ...
