Bar-Cohen, Yoseph, 1996, "(abstract) NDE and Advanced Actuators at JPL", https://hdl.handle.net/2014/27607, Los Angeles, CA, JPL Open Repository
JPL is responsible for deep space exploration using spacecraft and telerobotic technologies. Since all JPL's missions are one of a kind and hardware dependent, the requirements for nondestructive evaluation (NDE) of the materials and structures that are employed are significantly... |

Bar-Cohen, Yoseph; Backes, Paul; Joffe, Benjamin, 1996, "Rapid Inspection of Aerospace Structures - Is It Autonomous Yet?", https://hdl.handle.net/2014/26456, Seattle, WA, JPL Open Repository
The trend to increase the usage of aging aircraft added a great deal of urgency to the ongoing need for low-cost, rapid, simple-to-operate, reliable and efficient NDE methods for detection and characterization of flaws in aircraft structures. In many cases, the problem of inspect... |

Bar-Cohen, Yoseph, 1996, "(abstract) Application of Space Technology to NDE at JPL", https://hdl.handle.net/2014/27480, Los Angeles, CA, JPL Open Repository
JPL is responsible for the deep space exploration using spacecraft and telerobotic technologies. Since all its missions are one of a kind and hardware dependent, the NDE requirements are significantly more stringent than the ones for aerospace conventional needs. The multidiscipl... |
