Abstract: This study proposes a high computationally efficient data-driven predictive entry guidance method for hypersonic vehicles under multiple no-fly zones. The method uses a reduced-order motion-model-based semianalytic guidance ...

Abstract: The Xi’an City Wall (XCW) is a typical ancient building in Xi’an that is well known for its history and culture. The Xi’an Metro crosses below the XCW at various locations, which may pose hazards of cracking or collapsing ...

Abstract: In order to explore the deterioration characteristics of prestressed concrete under the coupling of freeze–thaw and corrosion, a series of aging tests and three-point bending tests was conducted. Furthermore, the deterioration ...
