Multi-sensor data fusion using geometric transformations for the nondestructive evaluation of gas transmission pipelines
<p>Nondestructive evaluation (NDE) plays a vital component in the operation and maintenance of large infrastructure such as gas transmission pipelines, nuclear power plants, aircraft, bridges and highways, etc. As this infrastructure continues to age it is essential that the inspection techniques …

A "divide-and-conquer" strategy for NDE signal inversion in gas transmission pipelines
<p>Signal inversion in nondestructive evaluation (NDE) applications is a critical step before remediation decisions are made. The accuracy and confidence of the signal inversion results therefore play a key role in evaluating the effectiveness of the NDE procedure. Conventional NDE signal inversion …
