"We deal with the Acoustic Emission (AE) principle as a Nondestructive Testing (NDT) method for the structural monitoring to achieve the target of precise geodesic localization of defects on the surfaces of solid bodies. We suppose the surfaces are mathematically described as a conjunction of several simpler parametric shapes with underlying mutual intersected one-dimensional areas. We use the Newton-Raphson procedure and we propose and test a few algorithmic improvements. On this basis we develop new efficient variants of localization algorithms employing Direct Search Methods (Compass algorithm, Reduced Newton method and Nelder-Mead method) for minimizing distinctions between the real measured time differences and the computed length differences found through geodesic curves. The whole procedure is applied to the real industrial data concerning quick and exact localization of the acoustic emission source on pressure vessel and also verified within our experiment on the Galvanized Steel Watering Can under consideration." . . .
