متن کاملThe hummingbird's tongue: a self-assembling capillary syphon.
We present the results of a combined experimental and theoretical investigation of the dynamics of drinking in ruby-throated hummingbirds. In vivo observations reveal elastocapillary deformation of the hummingbird's tongue and capillary suction along its length. By developing a theoretical model for the hummingbird's drinking process, we investigate how the elastocapillarity affects the energy ...
متن کاملSyphon dynamics - a soluble model of multi-agents cooperative behavior
We consider the dynamics of a “one queue one server” feedback queueing system where the decision of an agent to use the feedback loop is based upon its waiting time in the system. We investigate the dynamics for very patient agents and quantify the emerging stable and almost deterministic oscillations of the queue length. The resulting delay dynamics are due to the experience based decisions of...
