Dany Abboud 1 Details. Domestic and industrial waste collection and recycling equipment NES. In this work, the nonstationarity of the regime is confined to that of the speed— i. The proposed solution consists in generalizing the first-order cyclostationary class to the more general first-order cyclo-non-stationary class which enfolds speed-varying deterministic signals.
Unfortunately, most monitored machines used in the industry operate under nonstationary regimes in order to fulfill the task for which they have been designed. Friday, October 26, – But these works remain limited, dispersed and generally not supported by theoretical frameworks.

The principal goal of this thesis is to partially fill in this gap on the basis of a theoretical formalization of the subject and a systematic development of new dedicated signal processing tools.

Three different but complementary visions have been proposed to deal with the changes induced by the nonstationarity of the operating speed.

The second type includes random periodically-correlated waveforms known as second-order cyclostationary. Share this company profile. INSA de Lyon, In the tournants decades, vibration-based condition monitoring of rotating machine has gained special interest providing an efficient aid for maintenance in the industry.
Click on one of the tournabte to share the company. Nowadays, many efficient techniques are well-established, rooted on powerful tools offered in particular by the theory of cyclostationary processes. We have elaborated this strategy by distinguishing two types of signatures. Many tools have been conceived whose performances have been successfully tested on simulated and real vibration signals.
