Orbital Angular Momentum Holography Using Neural Network and Camera in the Loop

open access: yesLaser &Photonics Reviews, EarlyView.
Neural network and optimization‐based approaches are introduced for Orbital Angular Momentum (OAM) multiplexed holography, enabling high‐capacity, phase‐only image reconstruction. A Camera‐In‐The‐Loop (CITL) system learns a realistic propagation model to correct system imperfections.

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Laguerre-type Bell polynomials

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
We develop an extension of the classical Bell polynomials introducing the Laguerre-type version of this well-known mathematical tool. The Laguerre-type Bell polynomials are useful in order to compute the nth Laguerre-type derivatives of a composite ...

A q-Hankel transform associated to the quantum linking groupoid for the quantum SU(2) and E(2) groups

open access: yes, 2014
A q-analogue of Erdelyi's formula for the Hankel transform of the product of Laguerre polynomials is derived using the quantum linking groupoid between the quantum SU(2) and E(2) groups.

Fundamental Solutions and Green's Functions for Certain Elliptic Differential Operators From a Pseudodifferential Algebra

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We have studied possible applications of a particular pseudodifferential algebra in singular analysis for the construction of fundamental solutions and Green's functions of a certain class of elliptic partial differential operators. The pseudodifferential algebra considered in the present work, comprises degenerate partial differential ...

Poisson count time series

open access: yesJournal of Time Series Analysis, EarlyView.
This article reviews and compares popular methods, some old and some recent, that produce time series having Poisson marginal distributions. The article begins by narrating ways where time series with Poisson marginal distributions can be produced.

A Mixture Transition Distribution Modeling for Higher‐Order Circular Markov Processes

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT This study considers the stationary higher‐order Markov process for circular data by employing the mixture transition distribution modeling. The underlying circular transition distribution is based on Wehrly and Johnson's bivariate joint circular models.

Asymptotic expansions of the generalized Bessel polynomials

open access: yesJournal of Computational and Applied Mathematics, 1997
AbstractIn this paper, we investigate the asymptotic behavior of the generalized Bessel polynomials yn(z; a). Let z = α(n + 1). We first derive infinite asymptotic expansions for yn(z; a) when α lies in various regions of the complex plane, except when α is near ±i.
