Adaptive Independent Component Analysis–Based Cross-Correlation Techniques along with Empirical Mode Decomposition for Water Pipeline Leakage Localization Utilizing Acousto-Optic Sensors

Autor: Chang Hong Pua, Morris A. G. Ezra, Zijian Law, K. Mohanaprasad

Publikováno v: Journal of Pipeline Systems Engineering and Practice. 11

The leak localization in a water pipeline system plays a vital role in pipeline system modeling. The leak location is identified by estimating the time difference between two sensor signals...
