Figure 1 shows, in perspective, a diagram of the vibrating reed sedimentation analyser designed based on finite element analysis [2] for maximum sensitivity in response. 

It was noted early by Reed and others that the IETS spectrum could exhibit both absorption and emission peaks - that is, the plots of Fig. 9 could have positive excursions and negative excursions called peaks and dips. The simple analysis suggested in Fig. 9 implies that it should always be absorptive behavior, and therefore that there should always be a peak (a maximum, an enhancement) in the IETS spectrum at the vibrational resonances. It has been observed, however, that dips sometimes occur in these spectra. These have been particularly visible in small molecules in junctions, such as in the work of van Ruitenbeek [92, 109] (Fig. 12). Here, formal analysis indicates that, as the injection gap gets smaller, the existence of an inelastic vibrational channel does not contribute a second independent channel to the transport, but rather opens up an interference [100]. This interference can actually impede transport, resulting in a dip in the spectrum. Qualitatively, this occurs because the system is close to an electronic resonance without the vibrational coupling the conductance is close to g0, and the interference subtracts from the current. 

Picture analysis of the reference point located on the fabric has revealed an area of influence of the weaving reed during the compaction, which extends over approximately four inserted weft yarns in the fabric (Vilfayeau et al., 2014). Picture analysis of the reference point located on the heddle has revealed vibrational movements in the...
