Hiding the Source Based on Limited Flooding for Sensor Networks

open access: yesSensors, 2015
Wireless sensor networks are widely used to monitor valuable objects such as rare animals or armies. Once an object is detected, the source, i.e., the sensor nearest to the object, generates and periodically sends a packet about the object to the base ...

Acoustic Emission and Artificial Intelligence Procedure for Crack Source Localization

open access: yesSensors, 2023
The acoustic emission (AE) technique is one of the most widely used in the field of structural monitoring. Its popularity mainly stems from the fact that it belongs to the category of non-destructive techniques (NDT) and allows the passive monitoring of ...

Structural health monitoring of liquid filled above ground storage tank floors: a time reversed approach to acoustic emision source location

open access: yesEcomatemático, 2020
Acoustic Emission (AE) is a proven successful Non-Destructive Testing (NDT) method to assess the state of storage tank floors. Traditional AE source location in tanks floors is performed using only the wavefronts that have traveled directly from the ...
