The measurement of solid particle flow while measuring the sizes of particles at the same time presents a difficult problem. One of the possible solutions in relation to measuring the solid particle flow is the use of acoustic emission signal (AE) generated on the impact of the solid particles against a suitably chosen obstacle. The paper discusses the possible use of the acoustic emission signal...
The paper deals with the damage monitoring of concrete material structures by analysing the crack evolution by means of Acoustic Emission (AE). This analysis requires multi transducers, high sampling frequency and long time of observation. Triggered acquisition modality needs to avoid the saving of big size digitalized data. Due to the propagation in the concrete, the AE reduces its amplitude during...
