Wavelets

This book presents a systematic description of the fundamentals on wavelet transform and its applications to the condition monitoring and health diagnosis of rotating machine components and systems, such as bearings, spindles, and gearboxes. Given the widespread utilization of rotating machines in modern manufacturing and the increasing need for condition-based (instead of fix-interval), intelligent maintenance to minimize machine down time and ensure reliable production, it is of critical importance to advance the science base of signal processing in manufacturing. Focusing on wavelet transform as a tool specifically applied and designed for applications in manufacturing the material presented will be appropriate for both academic researchers and practicing engineers working in the field of manufacturing.
