Bio-inspired robotic dog paddling: kinematic and hydro-dynamic analysis.

abstract：:Small birds and mammals commonly minimize respiratory heat loss with reciprocating counterflow exchangers in their nasal passageways. These animals extract heat from the air in an exhalation to warm those passageways and then use that heat to warm the subsequent inhalation. Although the near-constant volume of buildin...
