The paper provides a state of the art review of guided wave based structural health
monitoring (SHM). First, the fundamental concepts of guided wave propagation and its …

It is well known that time-frequency analysis (TFA) characterises signals in time-frequency
plane. Theoretically, traditional non-parameterised TFA can analyze any signal, but it is …

An accurate prediction of cage-cultured water quality is a hot topic in smart mariculture.
Since the mariculturing environment is always open to its surroundings, the changes in …

Composite structures may be subjected to internal damages caused by impact events, which
can seriously degrade the property of the structures. Hence, impact monitoring is of great …

In this paper, we present an occupant localization approach through sensing footstep-
induced floor vibrations. Occupant location information is an important part of many smart …

Hydrogen has become a popular alternative energy to traditional fossil fuels due to its
potential to contribute to a more sustainable future. It is recognized that the safety, efficiency …

In this work, different types of artificial neural networks are investigated for the estimation of
the time of arrival (ToA) in acoustic emission (AE) signals. In particular, convolutional neural …

The impact localization is a typical inverse problem to identify the damage source of
structures. To overcome the positioning problems of the low resolution caused by sparse …

Identification of damage in its early stage can have a great contribution in decreasing the
maintenance costs and prolonging the life of valuable structures. Although conventional …

Ultrasonic guided wave is an effective tool for structural health monitoring of structures for
detecting defects. In practice, guided wave signals are dispersive and contain multiple …
