7: This oracle most clearly proves that Asclepius was not the son of Arsinoe, but that Hesiod or one of Hesiod's interpolators composed the verses to please the Messenians.
The exhibition beautifully reflects the pair's long-standing collaboration in which space becomes an interpolator for trust, witnessing, learning, and at times, for unlearning.
It is prevalent because it is an exact interpolator, i.e., the predictor for an input that has already been observed equals the observed output.
This interpolator uses a minimum-variance linear unbiased estimator, which considers the structure of spatial variability found for the variable.
[6] presented a real-time interpolation algorithm for NURBS curves; the proposed interpolator can maintain small contour errors and feed rate fluctuations.
Interpolate low resolution residuals ([[epsilon].sub.LR]) of the regression methods to high resolution residuals ([[epsilon].sub.HR]) with simple spline tension interpolator, respectively.
The PDEs System Interpolator. For a given signal [s.sub.0], the upper ([s.sup.+]) and lower ([s.sup.-]) envelope are the asymptotic solution of the following PDEs system:
A real-time surface interpolator methodology for precision CNC machining of swept surfaces.
Hence, the initial predictor switches between a non-directional static weighting interpolator for a smooth area, a one-directional interpolator for an edge area.
digital triggers allow for interpolation methods that can deliver sub-sample trigger resolution, like the PXIe-5164 oscilloscope interpolator which yields 1-ps resolution." R&S claims similar advantages and includes a highly expanded trace display in the company's literature to demonstrate the low trigger jitter that has been achieved.
