Nonstationary signal analysis is one of the main topics in the field of machinery fault
diagnosis. Time–frequency analysis can identify the signal frequency components, reveals …

This highly acclaimed work has so far been available only in French. It is a detailed survey of
a variety of techniques for time-frequency/time-scale analysis (the essence of" Wavelet …

Time frequency analysis has been the object of intense research activity in the last decade.
This book gives a self-contained account of methods recently introduced to analyze …

In the case of multicomponent signals with amplitude and frequency modulations, the
idealized representation which consists of weighted trajectories on the time-frequency (TF) …

A low cost, wearable textile-based respiratory sensing system is proposed and
experimentally demonstrated. A highly sensitive D-shaped plastic optical fiber (POF) sensor …

Unitary similarity transformations furnish a powerful vehicle for generating infinite generic
classes of signal analysis and processing tools based on concepts different from time …

Quantitative ultrasound has great potential for assessing human bone quality. Considered
as an elastic waveguide, long bone supports propagation of several guided modes, most of …

This chapter provides a response to the multifaceted question on the application of time–
frequency (TF): Which technique does one use and why? How does one use and implement …

The question of detecting a chirp in the time–frequency plane is addressed. Strategies
based on line integration are discussed with respect to optimality and adequacy of a …

We introduce a new set of tools for time-varying spectral analysis: the pseudo affine Wigner
distributions. Based on the affine Wigner distributions of J. and P. Bertrand (1992), these …
