Acoustic Emission (AE)
data analysis including real-time
extraction and data classification.
has been recognized by industry
and research institutions, as the most advanced tool
for AE data analysis and it is currently used in a large number of AE
world-wide, from industrial inspections to
It provides all the tools an analyst would
like to use in
industrial applications as well as for research
purposes with its very advanced data
manipulation functions. All Noesis functions are available to the
user with a few mouse clicks, and special wizards are available,
resulting in the most time effective means of treating AE data for
any application. PR and Neural Network algorithms, in combination with the
FX function and arbitrary data set and wave form support, allow deep
investigation of any data set, making Noesis a powerful research
tool. Moreover, all Noesis features are available for the real-time
analysis of data.

Selections reflect on ALL views, drastically
enhancing the users insight, even in real-time.
Data can be filtered, either graphically in plots, or from the data set
(data point removal) with simple filtering, selection
and delete operations. Complex Filtering can be applied through the Data
Filters dialog with set-up save/load capability.
Entire time segments can be removed.
Data projections can be generated based on covariance and correlation
matrices to project the data to a maximum
Copy/Paste operations are available for data transfer to other
applications. This includes data, waveforms/ DSP/ FFT

Classification during acquisition (Live-UPR)
is a complete set of Noesis functions to read and classify data during
acquisition. During Live-SPR, data can be manipulated as in post-
processing : change graphs, add graphs, select data, get statistics,
change scales etc.
Periodic Statistics is a set of Noesis functions for monitoring cluster
evolution and other features at certain intervals, which can be applied
either during acquisition or in post-processing
