Noise emission and structure of underexpanded radial jet and rectangular jet
Nihon Kikai Gakkai ronbunshu, 2018 An underexpanded radial jet is generated downstream of intake and exhaust valves of an internal combustion engine, a pressure control valve and so on. In addition, when a supersonic jet issuing from a circular nozzle impinges on a flat plate, the wall ...

Advanced Materials Technologies, EarlyView.Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...
