Time-frequency methods for condition based maintenance: call for papers

Call for Papers (CfP): Special issue on time-frequency methods for condition based maintenance and modal analysis

In recent years, research in the area of Condition-Based Maintenance (CBM) and Modal Analysis (MA) has been growing rapidly benefiting from the development of more advanced and accurate time-frequency methods. CBM is a decision making strategy which was introduced to recommend maintenance actions when the output of the sensors placed on the physical equipment fulfill a set of predefined criteria defining abnormal behaviors. CBM is based on using real-time data to prioritize and to optimize maintenance resources. It enables real-time diagnosis of impending failures and prognosis of remaining useful life of equipment without interrupting normal operations through analyzing and interpreting the measured data. Intensively used in CBM, the MA is concerned with the identification of the natural mode shapes and frequencies of structures or fluids under vibrational excitation.
Multi-purpose time-frequency methods like the short-time Fourier transform, the Wigner-Ville distribution or wavelets etc. are signal processing techniques which are applied in mechanical structures analysis for investigating functional parameters that are evolving in time like structural damages, cracks or deformations. Their usefulness in practice consists mainly in the fact that they are non-invasive techniques. This call for papers is aiming to stimulate not only new insides on the standard time-frequency techniques for signal processing but also recently developed methods like non-stationary Gabor frames, curvelets, adaptive wavelet families, sparse decompositions etc. with potential applications to dynamic data processing in manufacturing, mechanical structures and acoustics. Therefore, the main objective of this special issue is to bring the ideas of worldwide research community to present the latest developments and to advance the fields of CBM and MA through applications of the modern time-frequency processing techniques.

The following topics are of main interest:
  • Time-frequency methods for diagnostics, prognostics and features extraction
  • Time-frequency methods for modal analysis
  • Wavelet-based vibration monitoring and control
  • Natural frequencies identification
  • Sparse signal analysis
  • Online, segment-wise and parallel time-frequency implementations
  • Assessment studies of different signal processing techniques
  • Hardware and application constraints when building CBM systems
  • Applications in radar, mechanics, acoustics, etc.
The specified topics should be viewed as guidelines but any original interpretation of the signal processing methods for CBM and MA will be considered.

Time-frequency analysis and applications: call for papers

[Update 20120925] Special issue call for papers officialy released (deadline extended to 08/10/2012): Special issue on Time-frequency analysis and applications

The 4-page white paper should address: the motivations, importance, timeliness of the topics, an outline of the paper structure and content, some words about the authors (for the special issue editors). No style imposed: 4-page one-column would be enough.

Fresh from Eusipco 2012, a call for papers (cfp) is issued by the signal processing society, for IEEE Signal Processing Magazine:  Special issue on Time-frequency analysis and applications

The special issue (not yet on the special issue page) seeks to present recent advances in time-frequency (TF) signal analysis, using both linear and nonlinear decompositions.

Topics include:
  • advances in detection, estimation and classification using TF signatures
  • instantaneous frequency estimation
  • robust TF signal representations
  • new advances in TF localization and uncertainty principles
  • multidimensional extensions of TF concepts (instantaneous frequency, coherence, Riesz transform, etc.)
  • multi-sensor TF analysis and signal representations
  • TF domain processing, time-varying systems, Gabor multipliers, non diagonal denoising
  • data-driven methods e. g. Empirical mode decomposition (EMD), Hilbert-Huang transform and related techniques
  • reassignment, synchrosqueezing and phase-based methods.
