Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems
Asian Journal of Control, EarlyView.Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

Hematologic Observations on the Yak
Experimental Biology and Medicine, 1975 The uak has two hemoglobins sharing a common globin chain. Hb slow appears unique to the yak among the ruminants studied. It is not known if Hb slow is important in high altitude adaptation, but physilogic rather than hematolgoic adjustments may be more important agter acute blood loss, as 2,3-DPG remains nit and no disproportionate hemolgoin ...
