Frames associated with shift invariant spaces on positive half line
Acta Universitatis Sapientiae: Mathematica, 2021 In this paper, we introduce the notion of Walsh shift-invariant space and present a unified approach to the study of shift-invariant systems to be frames in L2(ℝ+).

Besov-type spaces for the κ-Hankel wavelet transform on the real line
Concrete Operators, 2021 In this paper, we shall introduce functions spaces as subspaces of Lpκ (ℝ) that we call Besov-κ-Hankel spaces and extend the concept of κ-Hankel wavelet transform in Lpκ(ℝ) space.

Reproducing Kernel Hilbert Space and Coalescence Hidden-variable Fractal Interpolation Functions
Demonstratio Mathematica, 2019 Reproducing Kernel Hilbert Spaces (RKHS) and their kernel are important tools which have been found to be incredibly useful in many areas like machine learning, complex analysis, probability theory, group representation theory and the theory of integral ...

Métodos tiempo-frecuencia basados en la transformada wavelet
Revista de Matemática: Teoría y Aplicaciones, 2012 La información contenida en una señal analógica se evidencia por su representación numérica. El par de Fourier en dos representaciones complementarias explicita las estructuras temporales y frecuenciales. Para detectar y caracterizar eventos que combinan

Scaling functions on the spectrum
Acta Universitatis Sapientiae: Mathematica, 2018 A generalization of Mallat’s classic theory of multiresolution analysis based on the theory of spectral pairs was considered by Gabardo and Nashed [4] for which the translation set Λ = {0, r/N}+2 ℤ is no longer a discrete subgroup of ℝ but a spectrum ...

CALDERÓN’S INVERSE PROBLEM WITH A FINITE NUMBER OF MEASUREMENTS
Forum of Mathematics, Sigma, 2019 We prove that an $L^{\infty }$ potential in the Schrödinger equation in three and higher dimensions can be uniquely determined from a finite number of boundary measurements, provided it belongs to a known finite dimensional subspace ${\mathcal{W}}$. As a

Polyphase matrix characterization of framelets on local fields of positive characteristic
Acta Universitatis Sapientiae: Mathematica, 2017 An important tool for the construction of framelets on local fields of positive characteristic using unitary extension principle was presented by Shah and Debnath [Tight wavelet frames on local fields, Analysis, 33 (2013), 293-307].

Quadratic phase S-Transform: Properties and uncertainty principles
e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023 In this paper, a novel quadratic phase S-transform (QPST) is proposed, by generalizing the S-transform (ST) with five parameters a, b, c,d and e. QPST displays the time and quadratic phase domain-frequency information jointly in the time-frequency plane.
