Dynamic Landing of an Autonomous Quadrotor on a Moving Platform in Turbulent Wind Conditions by Paris, Aleix, Lopez, Brett T., How, Jonathan P.

“…Previous works studied this problem but most lack explicit consideration of the wind disturbance, which typically leads to slow descents onto the platform. This work presents a fully autonomous vision-based system that addresses these limitations by tightly coupling the localization, planning, and control, thereby enabling fast and accurate landing on a moving platform. …”

Numerical analysis of effects of crosswind and turbulence intensity on aircraft wake-vortex in ground proximity by Sindhu Paramasivam

“…The plot of a~' versus velocity for downwind vortex at early times .varies linearly with a non-zero y-intercept while that of upwind vortex at later times can be approximated to a linear curve with slight deviations in low velocity regime. Vortex pair descents initially and then bounces back for all crosswind velocities. …”

Physiological parameters and nutrient uptake in unpuddled machine transplanted rice (Oryza sativa) in combination with alternative wetting and drying by SELVAKUMAR S, SHOBAN CHAKRAVARTHY K, AJAY KUMAR

“… A field study was carried out during rabi (winter) seasons of 2018–19 and 2019–20 at Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai, Tamil Nadu to study the effect of four different crop establishment methods, viz. manual transplanting; transplanting of rice seedling in puddled soil using machine; transplanting of rice seedling in non-puddled soil using machine; and direct sowing combined with four different irrigation treatments, viz. farmers practice; irrigation following the development of a hairline crack; irrigation when water level descents 5 cm; and 10 cm below soil surface on physiology of rice (Oryza sativa L.). …”

Swimming strategy and body plan of the world’s largest fish: implications for foraging efficiency and thermoregulation by Mark eMeekan, Lee eFuiman, Randall eDavis, Yuval eBerger, Michele eThums

“…However, sharks in the open ocean must access food resources that reside in relatively cold waters (up to 20oC cooler than the surface) at depths of 250-500 m during the daytime, where long, slow gliding descents, continuous ram ventilation of the gills and filter-feeding could rapidly cool the circulating blood and body tissues. …”
