On an Application of Lattice Integral Transforms in Image Processing

open access: yesMathematics, 2022
The lattice integral transforms have been introduced to generalize lower and upper fuzzy transforms for lattice-valued functions that are used to approximate original functions from below and above.

Green's function method for strength function in three-body continuum [PDF]

open access: yes, 2010
Practical methods to compute dipole strengths for a three-body system by using a discretized continuum are analyzed. New techniques involving Green's function are developed, either by correcting the tail of the approximate wave function in a direct ...

The Lorentz integral transform (LIT) method

open access: yes, 2008
The LIT approach is reviewed both for inclusive and exclusive reactions. It is shown that the method reduces a continuum state problem to a bound-state-like problem, which then can be solved with typical bound-state techniques.

Applications of New Double Integral Transform (Laplace–Sumudu Transform) in Mathematical Physics

open access: yesAbstract and Applied Analysis, 2021
The primary purpose of this research is to demonstrate an efficient replacement of double transform called the double Laplace–Sumudu transform (DLST) and prove some related theorems of the new double transform.

Coupling iterated Kolmogorov diffusions [PDF]

open access: yes, 2004
The Kolmogorov (1934) diffusion is the two-dimensional diffusion generated by real Brownian motion B and its time integral integral B d t. In this paper we construct successful co-adapted couplings for iterated Kolmogorov diffusions defined by adding ...

A New Integral Transform and Applications: HK-Transform

open access: yesZanco Journal of Pure and Applied Sciences
In this paper, we propose a new integral transform called the  Transform and employ it to analytically solve the Volterra integral equations (VIE.) of the first kind.

A transition integral transform obtained from generalization of the Fourier transform

open access: yesAin Shams Engineering Journal, 2019
We introduce a generalized integral transform (GIT) whose integration path lies on the complex plane. The GIT has both bilateral and unilateral versions, and generalizes a set of known integral transforms, e.g. Fourier, Laplace, allowing to solve integro-

Levy stable distributions via associated integral transform

open access: yes, 2012
We present a method of generation of exact and explicit forms of one-sided, heavy-tailed Levy stable probability distributions g_{\alpha}(x), 0 \leq x < \infty, 0 < \alpha < 1.

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between
