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
Cytokines are a class of immunoregulatory proteins that are secreted by cells.Although vertebrate cytokine, especially mammalian cytokine has been well studied for the past decades.Much less attention has been paid to invertebrate so that only some cytokines have been identified in invertebrates.We have chosen Peaneus vannamei as a model to explore
Pandemics grandpas best historically have killed as many people as the wars that have beset this world, yet the resources committed to pandemic prevention and response are a fraction of the resources we commit to security.This paper examines the COVID-19 pandemic of 2020 by analysing the preparedness and responses of the UK, the USA, Germany, and S
A set of fixed points in N-point gravitational lenses is studied in the paper.We use complex form of lens mapping to study fixed points.There are some merits of using a complex form over coordinate.In coordinate form gravitational lens is described by a system of two equations and in complex form is described by one equation.We transform complex eq
Broad and increasing interest in sustainable wastewater treatment has led a paradigm shift towards more efficient means of treatment system operation.A key aspect of improving overall sustainability southwestern aztec rug is the potential for direct wastewater effluent reuse.Anaerobic membrane bioreactors (AnMBRs) have been identified as an attract
