Maslow (1970) and Atkinson et al.(1990) consider motivation to relate to a number of basic human needs; Oxford and Shearin (1994), in an analysis of 12 motivational theories or models, identified six factors that relate to motivation (attitudes, beliefs about self, goals, involvement, environmental support and personal attributes).

Brie et al [4] found that depending on the demodulation type (amplitude or phase) the frequency band is different and he proposed adaptive methods to find the OFB (It should be noticed that due to varying operating conditions, that might cause amplitude and frequency modulations [12], vibration signature of damaged element (location of carrier and bandwidth) may be very different and it is important to know instantaneous value of speed and load [13, 14,17]). 2.4 Time-Frequency Domain Techniques Time-frequency methods include (among others) the Short-Time Fourier Transform (STFT), the Gabor transform, and the wavelet analysis, of which the last one has been extensively engaged in diagnostics of rotating machinery for several years [3,7,18].

The main empirical methods in literature are the Damage Probability index Method (DPM), proposed by Whitman et al. [2], and the Vulnerability Index Method (VIM) [3,4].
