The book provides readers with a snapshot of recent research and technological trends in the
field of condition monitoring of machinery working under a broad range of operating conditions.
Each chapter accepted after a rigorous peer-review process reports on an original piece of
work presented and discussed at the 4th International Conference on Condition Monitoring of
Machinery in Non-stationary Operations CMMNO 2014 held on December 15-16 2014 in Lyon
France. The contributions have been grouped into three different sections according to the main
subfield (signal processing data mining or condition monitoring techniques) they are related
to. The book includes both theoretical developments as well as a number of industrial case
studies in different areas including but not limited to: noise and vibration vibro-acoustic
diagnosis signal processing techniques diagnostic data analysis instantaneous speed
identification monitoring and diagnostic systems and dynamic andfault modeling. This book not
only provides a valuable resource for both academics and professionals in the field of
condition monitoring it also aims at facilitating communication and collaboration between the
two groups.
