RISRiver Flood Flow and Its Energy Loss
Publisher: American Society of Civil Engineers
Abstract: Due to the enlightenment from experiments performed in recent years, the kinetic energy equation has been applied to river flow, and results are presented. The main reason for discharge decrease in the main channel of river ...
Tornado Hazard Assessment of Residential Structures Built Using Cross-Laminated Timber and Light-Frame Wood Construction in the US
Publisher: ASCE
Abstract: Research has continued to broaden understanding of tornadoes and their effect on civil infrastructure. Because a significant portion of the losses associated with tornado events impact residential structures, it is appropriate ...
Multimodal Feeder Plan of Setting Flex-Route Transit for Metro Terminal Station in Suburb Considering Real-Time Demand Based on Slack Arrival Strategy
Publisher: ASCE
Abstract: This work aims to investigate a multimodal feeder plan for a metro terminal station in the suburbs, where fixed-route transit, flex-route feeder transit (FRFT), shared bike, online car-hailing, and private cars are included. ...
Dynamic Division of Control Subareas for Highway Networks Based on Improved Label Propagation Algorithm
Publisher: American Society of Civil Engineers
Abstract: The aim of this work is to investigate dynamic division of highway control subareas based on improved Label Propagation Algorithm (LPA) for implementing different signal control strategies in the subareas to improve operation ...
High-Frequency Single-Board Doppler Minisodar for Precipitation Measurements. Part I: Rainfall and Hail
Publisher: American Meteorological Society
Abstract: A high-frequency Doppler sodar for precipitation measurements has been developed. Such a Doppler sodar (6?20 kHz) can almost always measure precipitation and turbulence spectra simultaneously. Therefore, the mean vertical ...
Case Study of Potential Vorticity Tower in Three Explosive Cyclones over Eastern Asia
Publisher: American Meteorological Society
Abstract: hree cases of explosively developing extratropical cyclones over eastern Asia are analyzed using ERA-Interim data. The morphological characteristics of the upper-tropospheric potential vorticity (PV) were examined. The ...
Physically Based Green Roof Model
Publisher: American Society of Civil Engineers
Abstract: A green roof is a multilayered vegetated roof covering consisting of a root barrier, a waterproof membrane, an under drainage system, and a layer of growing medium covered by plants. The physical principles governing the ...
Elastoplastic Behavior of Case-Carburized 18Cr2Ni4WA Steel by Indenter Testing
Publisher: American Society of Civil Engineers
Abstract: The mechanical behavior of case-carburized 18Cr2Ni4WA steel is investigated by an optimization method combined with finite-element simulation based on indentation tests. For a measured load-displacement curve, the uniqueness ...
Optimization of Resilient Biofuel Infrastructure Systems under Natural Hazards
Publisher: American Society of Civil Engineers
Abstract: The writers aim to develop a new optimization framework that integrates resilience in biofuel infrastructure systems planning, which provides a proactive solution in mitigating the impacts of natural hazards on infrastructure ...
Investigation on Vibro-Impacts of Driveline System Based on a Nonlinear Clearance Element With Time-Varying Stiffness and Oil-Squeeze Damping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The transient vibro-impacts induced by clearance between the connected rotors in driveline system easily causes serious transient noise and vibration, especially between the gear teeth with backlash. To analyze the transient ...
