A warping operator consists of an invertible axisdeformation applied either in the signal domain or in thecorresponding Fourier domain. Additionally, a warping trans-formation is usually required to preserve the signal energy, thuspreserving orthogonality and being invertible by its adjoint.Initially, the design of such operators has been motivated bythe idea of suitably...

In this work, we address the transposition of a fragment of the modeling of the Sociology of Organized Action to the fuzzy setting. We present two different ways of developing fuzzy models in this context, that depend on the kind of available data furnished by the user: one based on the extension principle and another using fuzzy rule-based inference with similarity relations. We illustrate our...

Transposing an N × N array that is distributed rowor column-wise across P = N processors is a fundamental communication task that requires time-consuming interprocessor communication. It is the underlying communication task for the fast Fourier transform of long sequences and multi-dimensional arrays. It is also the key communication task for certain weather and climate models. A parallel trans...
