Hilbert–Huang analysis of BWR neutron detector signals: application to DR calculation and to corrupted signal analysis

Vibration analysis of a cracked rotor using Hilbert–Huang transform

“…Since its initial presentation by Huang et al [13] as a novel time-frequency analysis method in 1998, HHT has attracted more and more attention [16][17][18]. It has been introduced to vibration signal analysis by Yang and Suh [19], Yang and Lei [20], Peng et al [21].…”

Natural circulation and stability performance of BWRs (NACUSP)

“…The result was that some of the signals were strongly contaminated by noise and standard autoregressive methods do not provide good results. To overcome this difficulty a decomposition of the signal in intrinsic oscillation modes (IMF) was performed (Montesinos et al, 2003). In this way, consistent values of the decay ratio and oscillation frequency for all the signals.…”

“…Also, the computational volume in the wavelet transform method is high and so it is difficult to use it online. In recent years, a new method of time-frequency domain methods, called Hilbert-Huang's [2][3][4] transformation, has been gaining a lot of attention.…”
