High performance and resource efficient FFT processor based on CORDIC algorithm
EURASIP Journal on Advances in Signal Processing, 2022 Fast Fourier Transform is widely used in communication and signal processing. I propose an improved multipath delay commutator pipelining architecture based on the radix-2 time decimation algorithm.

Existence of Solution of Space–Time Fractional Diffusion-Wave Equation in Weighted Sobolev Space
Advances in Mathematical Physics, 2020 In this paper, we consider Cauchy problem of space-time fractional diffusion-wave equation. Applying Laplace transform and Fourier transform, we establish the existence of solution in terms of Mittag-Leffler function and prove its uniqueness in weighted ...

Reproducing Formulas for the Fourier-Like Multipliers Operators in q-Rubin Setting
International Journal of Analysis and Applications, 2020 The aim of this work is to study of the q^2 -Fourier multiplier operators on R_q and we give for them Calderon’s reproducing formulas and best approximation on the q^2-analogue Sobolev type space H_q using the theory of q^2-Fourier transform and ...

NONCOMMUTATIVE DE LEEUW THEOREMS
Forum of Mathematics, Sigma, 2015 Let $\text{H}$ be a subgroup of some locally compact group $\text{G}$. Assume that $\text{H}$ is approximable by discrete subgroups and that $\text{G}$ admits neighborhood bases which are almost invariant under conjugation by finite subsets of $\text{H}$.

A multiplier theorem for Fourier transforms [PDF]
Transactions of the American Mathematical Society, 1974 A function f analytic in the upper half-plane Π + {\Pi ^ + } is said to be of class E p ( Π + ) ( 0 > p > ∞ ) {E_p}({\

Advanced Engineering Materials, EarlyView.Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...
