The rolling element bearing is one of the most critical components that determine the
machinery health and its remaining lifetime in modern production machinery. Robust …

Fault diagnosis of rotating machinery is receiving more and more attentions. Vibration
signals of rotating machinery are commonly analyzed to extract features of faults, and the …

Fault detection of rotating machinery by the complex and non-stationary vibration signals
with noise is very difficult, especially at the early stages. Also, many failure mechanisms and …

Nonlinear characteristics are ubiquitous in the vibration signals produced by rolling element
bearings. Fractal dimensions are effective tools to illustrate nonlinearity. This paper …

This thesis presents six major contributions to the study on very low speed slew bearing
condition monitoring and prognosis:(1) review of studies on vibration and AE-based …

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

Rolling elements bearings are one of the most common components used in expensive,
high precision and critical machines such as gas turbines, rolling mills and gyroscopes …

This work presents an efficient Procedure for fault measurement of the single-input-single-
output (SISO) system by driving the system directly with the output of a chaotic oscillator …
