Abstract: This paper focuses on the relative motion and optimal impulsive formation reconfiguration near halo orbits. By applying the Floquet theorem, the time-varying system is simplified through a coordinate transformation, followed ...

Abstract: Land-use change has significant impacts on hydrologic processes at the watershed level; thus, quantitative assessment on the impacts of land-use change is vital for basin environment protection and water resources sustainable ...

Abstract: The flow regime of the Yangtze River (Changjiang) has been altered to some extent by intensified human activities over the past decades, particularly dam construction. To assess the impacts of dam building on the flow ...

Abstract: The reconfiguration of a constellation with several faulty satellites concerns performance improvements in multiple fields, which can be regarded as a multiobjective optimization (MOO) problem. In the optimization design, ...
