RISMultiobjective Reservoir Optimization Considering Sedimentation Applied to the Three Gorges Reservoir
Publisher: ASCE
Abstract: Increasing the power generation and reducing the sediment deposition in a reservoir are two contradictory and incommensurable objectives. Hence, these two operational objectives rarely are considered simultaneously in ...
Interaction between Strong Sound Waves and Cloud Droplets: Theoretical Analysis
Publisher: American Meteorological Society
Mechanical Properties of Bellows Joint-Connected Buried Pipelines Subjected to Normal Fault: Parametric Analysis
Publisher: American Society of Civil Engineers
Abstract: Buried pipelines that cross normal faults are at risk of damage because of insufficient deformation capacity. Bellows joints have been proven to have the potential to significantly increase the deformation capacity of the ...
Balancing Ecological Requirements and Power Generation in Reservoir Operation in Fish Spawning Seasons
Publisher: ASCE
Abstract: Various studies have demonstrated that the long-term flow regime plays an important role in stimulating fish spawning. The flow regime is altered by the construction and operation of reservoirs. In this study, a flow-regime ...
Gamma-Ray Spectrum Analysis of Chang’E-1 for Lunar Detection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gamma-ray spectrum analysis was essential for radioactive environmental monitoring, and it had been widely used in many areas of nuclear engineering. However, for the low-energy region of gamma-ray ...
Mechanism of Cloud Droplet Motion under Sound Wave Actions
Publisher: American Meteorological Society
Abstract: Sound waves have proven to be effective in promoting the interaction and aggregation of droplets. It is necessary to theoretically study the motion of particles in a sound field to develop new acoustic technology for ...
Fatigue Assessment for Deck-Rib Welded Joints of Orthotropic Steel Deck Using a Simplified Nodal Force Structural Stress Approach
