Nonparametric density estimates used for multiple AE source detection
Gális, P. ; Chlada, Milan
Paper deals with the localization of acoustic emission (AE) sources by means of exact geodesic curves on 3D vessels composed of several parametrized surfaces. Precise arrival times of AE events, plugged in DeltaT/DeltaL localization is discussed. Two-dimensional nonparametric (kernel) density estimates are employed to obtain the localization maps on 3-D surfaces and the potential regions of cracks are visibly highlighted. This newly proposed procedure is applied to steam reservoir and other experimental vessels. The results presented are accompanied by thoroughgoing evaluation of their quality and practical usefulness.
Heuristics in blind source separation
Kautský, Václav ; Štěch, Jakub
This paper deals with application of heuristic algorithms (DEBR, MCRS) in blind source separation (BSS). BSS methods focus on a separation of the (source) signal from a linear mixture. The idea of using heuristic algorithms is introduced on the independent component extraction (ICE) model. The motivation for considering heuristics is to obtain an initial guess needed by many ICE algorithms. Moreover, the comparison of this initialization, and other algorithms accuracy is performed.\n
