Investigation of a Bubble Detector based on Active Electrolocation of Weakly Electric Fish [PDF]
, 2013 Weakly electric fish employ active electrolocation for navigation and object detection. They emit an electric signal with their electric organ in the tail and sense the electric field with electroreceptors that are distributed over their skin. We adopted

Similitude Analysis for Gas-Liquid-Fiber Flows in Cocurrent Bubble Columns [PDF]
, 2006 Gas-liquid-fiber systems are different from conventional gas-liquid-solid systems in that the solid material (i.e., fiber) is flexible, has a large aspect ratio, and forms flocs or networks when its mass fraction is above a critical value.
