"Delta Space," an exercise in rich, wild counterpoint, distributes simple themes to a multitude of voices operating at different time frames and giving off variations of color.
The reason is that chimpanzee ancestors, well adapted for living off fruit in tropical forests, seem to have been adept at spinning off variations, such as gorillas who live on vegetation, and the human lineage, which exploited the drier woodlands that opened up between the forests.
But it can rev up familiar arrangements, as it did with "Tangled Up in Blue" (which had altered lyrics) or pull off variations: putting a Celtic-Appalachian banjo into "High Water (for Charley Patton)," making "The Lonesome Death of Hattie Carroll" into something like a folk minuet.
A section of the Renuzit Web site devoted to Renuzit Fresh Accents can be found at renuzit.com/hellogorgeous.(Coincidentally, ads in a campaign for new Tide Pods, which plays off variations on "pop," calls the tablets a "Pop of hello gorgeous").
Open image in new window Fig. 7 Run-off variation due in different conditions considering average daily rainfall.
The use of normalisation in frequency domain signals can also be used to reduce the effect of lift-off variation [78].
Thankfully, many researchers have attempted to overcome this problem and proposed techniques to eliminate or reduce the effect of lift-off variation.
PEC time responses can be normalized in order to reduce the effects of lift-off variation and varying magnetic permeabilities prior to the calculation of the above time-domain features [48].
Consequently, the right signal processing, signal analysis, feature extraction and classification model must be implemented in order to attain the desired parameters, such as coating thickness, size and position of defects, and to isolate them from the undesired parameters, such as lift-off variation.
