RISStrength and Deformation of Unburied and Buried Pipes in a Seabed Subsidence Area
Publisher: American Society of Civil Engineers
Abstract: AbstractSubsea pipelines face risks of failure in the seabed subsidence process. The pipe
stress and deformation in the seabed subsidence are analyzed based on the hypothesis
of a deformation beam model with elastic support ...
Robust Constrained Trajectory Tracking Control for Quadrotor Unmanned Aerial Vehicle Based on Disturbance Observers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a trajectory tracking control scheme for a quadrotor unmanned aerial vehicle (UAV) under unknown external disturbance and input saturation is developed. This scheme includes the position control system and ...

Improving the Heat Transfer Performance of the Tower Molten Salt Solar Receiver With the Novel Folded Flow Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The molten salt has been widely used in concentrated solar power generation as an effective high-temperature heat transfer and heat storage working fluid. However, due to the concentrating characteristic of the tower ...
A Forward Sensitivity Analysis and Design of U-Shaped Bellows Considering the Radial Compensation Capability Under Internal Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bellows serve as integral component within a piping system, which withstand radial displacement loads and internal pressure loads. This study investigates the sensitivity analysis of structure design parameters, such as ...
Research on the Mechanical Behavior and Energy Evolution of Rock Joints during the Loading–Unloading Shear Process
Publisher: American Society of Civil Engineers
Abstract: Abstract The high degree of jointing in natural rock masses has a significant impact on their
mechanical behavior. The joints are subjected to frequent loading and unloading during
excavation. Therefore, this paper researches ...
Mechanism of Landfill Leakage Induced by Surface Subsidence and Cracking during Deep Mining and the Migration Law of Pollutants in Groundwater
Publisher: American Society of Civil Engineers
Abstract: Abstract There are a large number of potential pollution sources distributed on the Earth’s
surface, such as landfills, tailings ponds, and industrial waste yard. Deep mining
will induce subsidence movement of rock stratum, ...
The Response of the Southern Hemisphere Middle Atmosphere to the Madden–Julian Oscillation during Austral Winter Using the Specified-Dynamics Whole Atmosphere Community Climate Model
Publisher: American Meteorological Society
Abstract: AbstractUsing the specified-dynamics (SD) Whole Atmosphere Community Climate Model (SD-WACCM), the effects of the Madden?Julian oscillation (MJO) on the midwinter stratosphere and mesosphere in the Southern Hemisphere (SH) ...
Study on the Salt Scaling Resistance of Pavement Cement Concrete
Publisher: American Society of Civil Engineers
Abstract: The single-side salt-freeze test was used to optimize the concrete mix design for improving the resistance of concrete to salt scaling. The results show that the resistance of concrete to salt scaling improves with decreasing ...
