Abstract: This paper aims to investigate the airfoil flutter damage-mitigating problem in hypersonic flow. A new adaptive robust nonlinear predictive control law is designed in this paper to mitigate the damage during airfoil flutter ...

Abstract: Bifurcation behavior analysis is the key part of mobility in the application of origami-inspired deployable structures because it opens up more allosteric possibilities but leads to control difficulties. A novel tracking ...

Abstract: AbstractThis research employed micro- and macroscale experiments combined with numerical simulation to investigate oil production using different CO2 flooding methods. Microscale experiments visualized oil displacement via ...

Abstract: AbstractThe replacement of traditional concrete with RC can effectively alleviate nonrenewable resource depletion, ecosystem damage, and environmental pollution caused by the large-scale use of concrete-filled steel tubes. ...

Abstract: This study extended the knowledge over the improvement of the control performance for a seven degrees-of-freedom (7DOF) humanoid arm. An improved adaptive Gaussian radius basic function neural network (RBFNN) approach was ...

Abstract: Fabrication of cellular spheroids is critical for creating functional tissue units and investigating the mechanism of tumorigenesis, development, and intercellular and cell–matrix interactions in vitro. Herein, we developed ...
