RISAccident-Oriented Delay Propagation in High-Speed Railway Network
Publisher: ASCE
Abstract: This paper presents an approach to estimate the delay propagation in a high-speed railway (HSR) network under accident conditions. Considering the complexity and dynamics of HSR accidents, different levels of delay are ...
Drop Size and Velocity Measurements in an Electrostatically Produced Hydrocarbon Spray
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Liquid hydrocarbons are difficult to atomize electrostatically at practical flow rates due to their high resistivities and low concentration of charge carriers. However special “charge injection” ...
Updating Fatigue Damage Coefficient in Railway Bridge Design Code in China
Publisher: American Society of Civil Engineers
Abstract: Railway traffic volumes in China have increased dramatically with the fast development of the Chinese economy in the past 20 years. The load frequency spectra of bridges have also changed as a result. Therefore, it is ...
A Two-Dimensional Adjustable Constant-Force Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Constant-force mechanisms (CFMs) can produce an almost invariant output force over a limited range of input displacement. Without using additional sensor and force controller, adjustable CFMs can passively produce an ...
Elastoplastic Deformation Characteristics of Gravelly Soils
Publisher: American Society of Civil Engineers
Abstract: This study explores the elastoplastic deformational behavior of gravelly soils. A series of drained triaxial tests with controlled stress paths [conventional triaxial compression (CTC) and conventional triaxial extension ...

Toward an Operational Land Surface Temperature Algorithm for GOES
Publisher: American Meteorological Society
Abstract: or most land surface temperature (LST) regression algorithms, a set of optimized coefficients is determined by manual separation of the different subdivisions of atmospheric and surface conditions. In this study, a ...
Empirical Environment Construction Research of Developing EMC in Transportation Industry
Publisher: American Society of Civil Engineers
Abstract: This study aims to satisfy the energy management contract (EMC) work schedule of the Ministry of Transport (MOT). The paper first defines EMC together with its connotations to clarify its specific demands for the market ...
Coupled Coordination Relationships between Economy and Ecosystem Services at the County Scale: Evidence from the Guanzhong Plain Urban Agglomeration in China
Publisher: American Society of Civil Engineers
Abstract: Abstract Understanding the relationship between urban economic growth and ecosystem services
is important in sustainable spatial planning, enabling urban managers to establish
a coordinated development model. However, there ...
Hydraulic Conductivity of Sand/Biopolymer-Amended Bentonite Backfills in Vertical Cutoff Walls Permeated with Lead Solutions
Publisher: ASCE
Abstract: This study investigated the hydraulic conductivity and microscopic properties of two backfills, conventional sand/bentonite (SB) and sand/xanthan gum (XG)-amended bentonite/sand (XG-SB), for use in vertical cutoff walls ...
