Time-Frequency Concentration Associated with the Multidimensional Hankel-Wavelet Transform

Pan-American Journal of Mathematics
The main goal of this paper is to define a new integral transform called the multidimensional Hankel-wavelet transform and to give some new results related to this transform as generalized Parseval’s, Plancherel’s, inversion and Calderon’s reproducing ...

Copper ratio obtained by generalizing the Fibonacci sequence

AIP Advances
In this study, we define a new generalization of the Fibonacci sequence that gives the copper ratio, and we will call it the copper Fibonacci sequence. In addition, inspired by the copper Fibonacci definition, we also define copper Lucas sequences, and ...

Solutions to Time-Fractional Diffusion-Wave Equation in Cylindrical Coordinates

Advances in Difference Equations, 2011
Nonaxisymmetric solutions to time-fractional diffusion-wave equation with a source term in cylindrical coordinates are obtained for an infinite medium. The solutions are found using the Laplace transform with respect to time , the Hankel transform with ...

Sound sources of high directivity

Archives of Acoustics, 2014
The reversibility of Hankel transform suggests the possibility of constructing such a sound source which radiates only within a certain cone. Both the approximate and accurate theories of that source are given. It is proved in the paper that the accurate

The applications of Hankel transform to the computation of nearfields of circular baflled sources

Archives of Acoustics, 2014
In the present paper we give a new method of computation of near sound fields emitted by baffled circular sources. We have applied the Hankel transform and King's integral.
