This paper investigates optimal power management of a fuel cell hybrid small unmanned aerial vehicle (sUAV) from the perspective of endurance (time of flight) maximization in a stochastic environment.Stochastic drift counteraction optimal control is exploited to obtain an optimal policy for power management that coordinates the operation of the fue
On the basis of regional seismic interpretation of the northern Songliao Basin and the analysis of fault geometry characteristics and the formation and evolution of faults, this paper analyses fault deformation mechanisms at different stages, which reveal the formation mechanism of inversion structures and their role for oil and gas migration and a
A shallow water equations-based model with an improved local time-stepping (LTS) scheme is developed for modeling coastal hydrodynamics across multiple scales, from large areas to detailed local regions.To enhance the stability of the shallow water model for long-duration simulations and at larger LTS gradings, a prediction-correction method using
