Abstract: For reservoirs with multiple water demands, losses in water use utility because of shortages in the water supply from historical operation decisions can be considered information to improve the current decisions. This study ...

Abstract: This paper presents modeling and control law design for a bi-tiltrotor unmanned aerial vehicle for autonomous payload delivery. An ultralight bi-tiltrotor aerial vehicle was developed for a payload delivery contest using ...

Abstract: The constitutive model in geotechnical engineering plays a critical role, driving the need for ongoing research and improvement. In this study, by utilizing a single yield curve and only one hardening parameter, a nonorthogonal ...

Abstract: There is a need for a unified strength criterion, which is a variable suitable for describing the different strength properties of different types of geomaterials. There have been efforts to develop unified strength criteria; ...

Abstract: Entrainment of sediment from hillslope and channel usually has a significant influence on resistance of debris flow. This effect is studied by flume experiments of debris flow over rigid and erodible beds. Fifty contrast ...

Abstract: Dust is the major aerosol type over the Tibetan Plateau (TP), and the TP plays an important role in forming the spring dust belt across the Northern Hemisphere in the upper troposphere. Estimated spring dust mass flux (DMF) ...

Abstract: The optimal allocation of crop area can improve the management of agricultural water resources for sustaining agricultural productivity and sustainable development. In this study, an approach that integrated the multiobjective ...

Abstract: A temperature-control curtain (TCC) is an effective facility to regulate the outflow temperature in reservoirs, and its safety and stability are of great concern. The pressure difference between the front and back of a TCC ...
