James W. Wagner
1988 Review of Progress in Quantitative Nondestructive Evaluation  
ACKNOWLEDGE~ffiNT Work supported in part by the US Navy Office of Naval Research.  ...  Note the small gouge running the center of this contoured region. This gouge is not apparent at all from the stationary or homodyne interference image.  ...  Upon reconstruction of the hologram an image such as that shown in Figure 4 is observed where one can clearly see the lateral deflection of the fringes as they describe the contour of the surface.  ...

Voiced speech as secondary response of a self-consistent fundamental drive [article]

Friedhelm R. Drepper
2006 arXiv   pre-print
The present study is focussed on the adaptation of the trajectories (contours) of the centre filter frequency of the part-tones to the chirp of the glottal master oscillator.  ...  The universality and robustness of human pitch perception encourages the reconstruction of a band-limited FD in the frequency range of the pitch.  ...  The latter one is usually described as an aggregate of contributions from a range of audiological (critical) subbands and from a range of observation times.  ...
