RISEffect of Activated Fly Ash on Engineering Properties and Soil Structure in a Compacted Natural Soil Liner
Publisher: American Society of Civil Engineers
Abstract: AbstractReducing the permeability of landfill lining to effectively prevent heavy metal ions
migration is the key to achieve sustainable development of landfills. In this study,
we utilized Pb2+ and Ni2+ ions as sources ...
A Contra-Rotating Open Rotor Noise Reduction Methodology by Using Anhedral Blade Tip
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, a novel contra-rotating open rotor (CROR) noise reduction methodology based on the anhedral blade tip applied to the front blade is developed. Results indicate that anhedral blade tip can provide noise ...
In-Ground-Effect Modeling and Nonlinear-Disturbance Observer for Multirotor Unmanned Aerial Vehicle Control
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on modeling and control of in-ground-effect (IGE) on multirotor unmanned aerial vehicles (UAVs). As the vehicle flies and hovers over, around, or underneath obstacles, such as the ground, ceiling, and ...
