Structural health monitoring (SHM) systems in civil engineering structures have been a
growing focus of research and practice. Over the last few decades, optical fibre sensor (OFS) …

Distributed optical fiber sensing is a unique technology that offers unprecedented
advantages and performance, especially in those experimental fields where requirements …

Leakages in pipelines affect the reliability of fluid transport systems causing environmental
damages, economic losses, and pressure reduction at the delivery points. Therefore, this …

Low localization accuracy and instability have always been two primary problems for the
pipeline leak detection and localization method based on the negative pressure wave …

There is an increasing need for timely pipeline leak detection and localization methods,
pipeline leak could lead to not only the loss of the goods but also considerable …

In this paper, based on the research of fiber optic sensing technology, a multiparameter
measuring system for hydraulic parameter monitoring is developed and evaluated. The …

We propose and experimental demonstrate a Dynamic Threshold Identification Method
(DTIM) based on the Raman distributed fiber sensor (RDFS) system for detecting the …

The combined length of the sewerage and clean water pipe infrastructure in the UK is
estimated to be about 800,000 km. It is prone to failure due to its age and the inadequacies …

Pipeline leakage and pipeline internal corrosion are two serious threats to pipeline safety
operation. In this study, based on the measurement theory of pipeline internal diameter …

The drinking water mains, mostly buried underground and stay there for decades, require
proper maintenance to prevent failures. Among different kinds of material, polyvinyl chloride …
