RISSocial Media Support Mechanisms for Organizational Adaptation in Governmental Response to Extreme Natural Hazards
Publisher: ASCE
Abstract: Extreme natural hazards pose huge challenges to public administration. In the era of social media, governmental response takes the form of complex adaptive systems, applying information technology to support public ...
Hydrodynamic Performance and Wake Topology of Schooling Fish in Three-Dimensional Formations
Publisher: The American Society of Mechanical Engineers (ASME)
A Computational Study of In-Phase and Anti-Phase Interactions of Fish in a Phalanx School
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biological studies have shown that schooling behavior benefits fish's swimming performance. Particularly, side-by-side, or phalanx, formation, combined with the synchronization of undulation of the neighbors, was shown to ...
Self-Organization Response in a Crisis: A Case Study of a Shanghai Community during COVID-19 in 2022
Publisher: American Society of Civil Engineers
Abstract: AbstractThis study examines how self-organizing groups function during crisis response in
China’s centralized system. Through case analysis of a Shanghai community during COVID-19,
we investigate how emergent citizen groups ...
FPSO-Shuttle Tanker Collision Risk Reduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To reduce the occurrence of tanker drive-off, and to reduce the probability of recovery failure should drive-off happen, are two basic principles to reduce FPSO and DP shuttle tanker collision ...
Spatiotemporal Characteristics of Rainstorm-Induced Hazards Modified by Urbanization in Beijing
Publisher: American Meteorological Society
Abstract: he rainfall data of 20 rain gauge stations are used for analysis on the spatiotemporal characteristics of rainstorm-induced hazards in Beijing. A local model used to calculate rainstorm hazards index values (RHIVs) has ...
Effect of Different Lime-Anhydrite Ratios on the Hydration Process of Sulfoaluminate Cement
Publisher: ASCE
Abstract: In this paper, the influence of lime-anhydrite (L/A) ratio on the strength development, cement hydration, and setting time of calcium sulfoaluminate cement (CSA) is systemically investigated. Based on Raman spectroscopy ...
Design and Analysis of a Multi-Knuckle Coupled Grasper With Equal Angles at Each Knuckle During Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a coupled multi-knuckle mechanical finger was designed. The finger is composed of same-structured knuckles in a connecting link structure, and the knuckles can be combined arbitrarily. The coupling motion ...
