Sample entropy (SampEn) has been applied in many literatures as a statistical feature to
describe the regularity of a time series. However, as components of mechanical system …

As a prerequisite for rotating machinery to operate effectively, rolling element bearings play
an essential role. The focus of condition monitoring has initially been on defect identification …

Nonlinear fault responses are common in industrial systems yet cannot be effectively
extracted by traditional feature extraction methods. In recent years, more techniques based …

Some healthy/faulty conditions in rotating machinery lead to nonlinear dynamics of system.
In these conditions, early fault detection of rotating machinery is a hard problem to solve …

Rolling element bearing is not only the most important failure unit in rotary machinery, but it
is also the most common, and its performance degradation assessment has been proposed …

Nonlinear damage is a common occurrence for mechanical systems in service, whereas the
studies concerning the diagnosis of nonlinear damage are often limited due to the intensive …

In the present study, the vibrational and frictional torque signals acquired from the forward-
backward movements of a commercial ball-screw system were considered via mono fractal …

In structural health monitoring, it is often the case that the dynamics of the structure being
monitored are appropriately described by a nonlinear model. The statistical properties of the …

The rolling element bearing plays a significant role in any mechanical manufacturing
industry. Bearing fault diagnosis using vibration signal processing has been a vital subject of …
