Linear Model and Regularization for Transient Wave–Based Pipeline-Condition Assessment

AbstractCondition assessment or defect detection of a pipeline is a difficult inverse problem. This paper proposes a general linear model framework that can approximately describe a wide range of p...

Usage and Effect of Multiple Transient Tests for Pipeline Leak Detection

AbstractThe value of multiple transient tests under the same experimental conditions for the purpose of leakage detection is assessed. The gain in signal-to-noise ratio and leakage detection accura...

Pipeline leak detection using the multiple signal classification-like method

The MUSIC-like method is capable of identifying all leaks where the leak-to-leak distance is less than half the shortest probing wavelength and has an excellent performance in leak detection and location.

Leak Location Based on PDS-VMD of Leakage-Induced Vibration Signal Under Low SNR in Water-Supply Pipelines

The simulation and experimental results demonstrate that the proposed PDS-VMD method is more suitable for leak location in WSP, which provides immunity to both broadband and narrow band noise under low SNR.



Frequency Domain Analysis for Detecting Pipeline Leaks

This paper introduces leak detection methods that involve the injection of a fluid transient into the pipeline, with the resultant transient trace analyzed in the frequency domain. Two methods of

A subspace rotation approach to signal parameter estimation

A new approach to Estimation of Signal Parameters by Rotational Invariance Techniques (ESPRIT) is described in the context of direction-of-arrival estimation, but is also applicable to other

Adaptivity to background noise spatial coherence for high resolution passive methods

It is shown in this paper that if the spatial coherence of the background noise is not exactly known but can be modelized by a function which depends on some parameters, these parameters can be estimated and the high resolution method carried out.

Pipeline Network Features and Leak Detection by Cross-Correlation Analysis of Reflected Waves

This paper describes progress on a new technique to detect pipeline features and leaks using signal processing of a pressure wave measurement. Previous work (by the present authors) has shown that

Two decades of array signal processing research: the parametric approach

The article consists of background material and of the basic problem formulation, and introduces spectral-based algorithmic solutions to the signal parameter estimation problem and contrast these suboptimal solutions to parametric methods.
