Gas pipelines are prone to faults due to aging, corrosion, and external factors. Undetected
faults can result in injuries, damage to properties, and environmental contamination. Several …

Leakages are undesirable events in water distribution networks (WDNs) with mostly
unknown incident time making it extremely difficult to accurately label leaks in distribution …

A nuclear power plant (NPP) consists of an enormous number of components with complex
interconnections. Various techniques to detect sensor errors have been developed to …

This work proposes a proportional-integral fault estimation observer for nonlinear systems
by means of convex structures. Unlike the traditional approaches that consider quadratic …

Morphological filtering shows effectiveness in vibration signal analysis because of its
simplicity and efficiency. Considering that different structural elements have different effects …

As flanged pipes have a crucial role in oil and gas transportation, accidental leaks and their
detection are of great importance, and represent a great concern in safety management of …

This study presents a comprehensive fault diagnosis method for rolling bearings. The
method includes two parts: the fault detection and the fault classification. In the stage of fault …

Conventional leak detection techniques require improvements to detect small leakage (<
10%) in gas mixture pipelines under transient conditions. The current study is aimed to …

There is an urgent need for industrial Internet of things (IoT) solutions to deploy a smart
hydrophone sensor grid to monitor pipeline health and to provide an accurate prediction in …

Aiming at fault feature extraction of a hydraulic pump signal, a new method based on
symplectic geometry mode decomposition (SGMD) and power spectral entropy (PSE) is …
