Proceedings of the 7th conference of the European Society for Fuzzy Logic and Technology (EUSFLAT-2011), 2011 The fuzzy transform (F-transform for short) is a universal tool for a fuzzy modeling with convincing applications to image processing. The aim of this contribution is to explain the eect of the Ftransform in image processing. With this purpose, we investigate properties of the Fourier transform over the F-transform components.

Higher Order Riesz Transforms for Fourier-Bessel Expansions
, 2012 In this paper we investigate the Riesz transforms of order d ≥ 1, R d v, for Fourier-Bessel expansions. Weighted norm inequalities are proved for this operator.

Rearrangement estimates for fourier transforms in Lp and Hp in terms of moduli of continuity [PDF]
, 2001 One of the main purposes of this paper is to obtain estimates for Fourier transforms of functions in Lp(ℝn) (1 ≤ p ≤ 2) in terms of their moduli of continuity.

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies
Advanced Engineering Materials, EarlyView.Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

THE YANG-FOURIER TRANSFORMS TO HEAT-CONDUCTION IN A SEMI-INFINITE FRACTAL BAR
, 2013 1-D fractal heat-conduction problem in a fractal semi-infinite bar has been developed by local fractional calculus employing the analytical Yang-Fourier transforms method. The simplicity and the accuracy of the method are discussed.

On Fourier Transforms of Radial Functions and Distributions [PDF]
, 2011 We find a formula that relates the Fourier transform of a radial function on Rn with the Fourier transform of the same function defined on Rn+2. This formula enables one to explicitly calculate the Fourier transform of any radial function f(r) in any ...
