RISA Preliminary Survey of Clear-Air Echo Appearances over the Kanto Plain in Japan from July to December 1997
Publisher: American Meteorological Society
Abstract: A preliminary survey of clear-air echo appearances over the Kanto plain in Japan from July to December 1997 is presented. A distinct contrast was seen between clear-air echoes observed over land and their absence over the ...

Automatic Generation of 3D Building Models from Complicated Building Polygons
Publisher: American Society of Civil Engineers
Abstract: A three-dimensional (3D) urban model is an important information infrastructure that can be utilized in several fields, such as urban planning and game industries. However, enormous time and effort have to be spent to ...
Energy Harvesting from Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: In recent years wireless sensors are becoming more widely used to monitor water distribution systems in the water supply industry. When sensors are installed in areas where electric power supply is lacking and/or battery ...
Development of a Phase-Field Method for Phase Change Simulations Using a Conservative Allen–Cahn Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase flows including a phase change such as liquid–vapor flows play an important role in many industrial applications. A deeper understanding of the phase change phenomena is required to improve performance and safety ...
Isolation Valve Placement Strategy for Resilience Improvement of Water Distribution Systems
Publisher: ASCE
Abstract: This study proposes a novel optimal isolation valve placement method for water distribution networks (WDNs) using dynamic programming. The proposed method automatically finds the best places to install isolation valves ...
Time-Independent and Time-Dependent Inelastic Strain Analysis of Lead-Free Solder by Cyclic Loading Test Using Stepped Ramp Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We previously proposed an elastic-plastic-creep model to estimate the fatigue strength of lead-free solder joints subjected to cyclic thermal loading. The proposed model requires detailed experimental ...
Investigation of Effect of Creep Strain on Low-Cycle Fatigue of Lead-Free Solder by Cyclic Loading Using Stepped Ramp Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fatigue life of a material varies with the strain rate if it has time-dependent deformation. An interesting phenomenon related to the effect of the strain rate on the fatigue life can ...
High-Accuracy Analysis of Beams of Bimodulus Materials
Publisher: American Society of Civil Engineers
Abstract: Recently, several authors have treated the problems of bending of beams of bimodulus materials. The present paper, applies Levinson beam theory, which includes shear deformation and warping of the cross section, to bending ...
Coupling between Tropospheric and Stratospheric Leading Modes
Publisher: American Meteorological Society
Abstract: Coupling between tropospheric and stratospheric leading modes in anomaly fields is investigated. By using daily data at many levels in addition to monthly mean data, the transition of spatial patterns and the direction and ...
