This study presents the design of an intelligent robust controller for the 3-degree-of-freedom motion of an aerial 7.40 robot using waterpower.The proposed controller consists of two parts: (1) an anti-windup super-twisting algorithm that provides stability to the system under actuator saturation; and (2) a fully adaptive radial basis function neur

Penguins are the utmost specialized wing-propelled divers as their flapping action is accountable for the entire underwater propulsion.However, numerical evidence of how efficient their underwater propulsion is has not been studied to date.Literature sources suggest that propulsive efficiency peaks when the Strouhal number (St) ranges between 0.2 a

The gray partridge Perdix perdix was once a common breeding bird in Britain and a traditional quarry species.Its numbers have declined by over 90% over the last 50 years, and there have been similar declines across Europe.Since 1968 the Game and Wildlife Conservation Trust (GWCT) has Accessories undertaken research on this decline and identified th

Activation energies ΔGact for the nucleation of nitric acid dihydrate (NAD) in supercooled binary HNO3/H2O solution droplets were calculated from volume-based nucleation rate measurements using the AIDA (Aerosol, Interactions, and Dynamics in the Atmosphere) aerosol chamber of Accessories Forschungszentrum Karlsruhe.The experimental condition
