Ultrasonic Non-Destructive Testing (NDT) Using Wireless Sensor Networks
Procedia Computer Science, 2012 AbstractThis paper describes the integration of an ultrasonic-based non-destructive testing (NDT) with wireless sensor networks (WSNs) to continuously monitor material integrity during run-time. NDT is a technique that allows the examination of material properties without causing any damage to the material in the process.
