Abstract: This paper presents a new robust output feedback guidance scheme for autonomous spacecraft rendezvous during the final phase in elliptical orbit. The proposed approach is essentially a compound control method, which consists ...

Abstract: This paper considers the application of compound control method to high-performance autopilot design for aerodynamically controlled agile missiles. The control objective in this paper is to track a reference angle of attack ...

Abstract: Damage to pipeline welds during service can result in substantial human and economic losses. Hence, early and accurate quality diagnosis of in-service natural gas pipeline welds is of utmost importance. However, the current ...

Abstract: The end-effector angle is defined as the angle between the end-effector axial axis and the hand axis (an axis from the wrist center to the end-effector reference point). Most industrial ...

Abstract: The simulation of dynamic water pressure is one of the basic methods that should be researched to improve the resistance of an asphalt mixture to water damage. In this study a test system that generates dynamic water ...

Abstract: An elastic contact model for three-dimensional layered or coated materials under coupled normal and tangential loads, with consideration of partial slip effects, has been developed in this paper. ...

Abstract: A numerical approach for solving the fretting contact on coated or layered materials, with consideration of loading history, is presented in the paper. The fretting problem was solved by using ...

Abstract: Sedimentation in the Three Gorges Reservoir (TGR) has been studied with a primary focus on the amount due to the decrease in sediment inflow caused by water and soil conservation projects and sediment retention of recently ...

Abstract: Surcharge preloading is a suitable foundation treatment for high-speed railways in soft soil regions. As a temporary preload on the foundation, the surcharge load must be removed before track construction. In this process, ...
