Abstract: A new fractional-order sliding mode control (FOSMC) scheme is investigated for air-breathing hypersonic vehicles (AHVs). The control scheme proposed is designed based on linear-quadratic optimal theory. First, by using the ...

Abstract: Based on the vibro-acoustic coupled model of an infinite bare plate, using the impedance transfer matrix, the analytical model predicting the noise reduction performance of a void decoupling ...

Abstract: Weak interlayers determine the strength and stability of a jointed rock mass. The influence of weak interlayer filling state on the shear strength and failure patterns of a rock mass was studied by direct shear testing. ...

Abstract: With simple structure, excellent reliability, low cost, no restriction at depth of water, and easy control and operation, airlift pumps have special advantage in borehole hydraulic jet mining, ...

Abstract: he U.S. Geological Survey (USGS) land use (LU) data employed in the Weather Research and Forecasting (WRF) model classify most LU types in Taiwan as mixtures of irrigated cropland and forest, which is not an accurate ...
