Fractional operators and their commutators on generalized Orlicz spaces [PDF]

open access: yesOpuscula Mathematica, 2022
In this paper we examine boundedness of fractional maximal operator. The main focus is on commutators and maximal commutators on generalized Orlicz spaces (also known as Musielak-Orlicz spaces) for fractional maximal functions and Riesz potentials.

A new approach for SPN removal: nearest value based mean filter [PDF]

open access: yesPeerJ Computer Science, 2022
In this study, a new adaptive filter is proposed to eliminate salt and pepper noise (SPN). The basis of the proposed method consists of two-stages. (1) Changing the noisy pixel value with the closest pixel value or assigning their average to the noisy ...

Variation in the Oxidative State of Collared Flycatcher (<i>Ficedula albicollis</i>) Nestlings and Its Association With Their Plumage Coloration. [PDF]

open access: yesEcol Evol
Plumage coloration is widely recognized as an important component in intraspecific communication. Our aim was to examine the variation of oxidative parameters and their associations with the coloration of two different nestling plumage traits in collared flycatchers (Ficedula albicollis).

A class of fractional Ornstein–Uhlenbeck processes mixed with a Gamma distribution

open access: yesModern Stochastics: Theory and Applications, 2022
We consider a sequence of fractional Ornstein–Uhlenbeck processes, that are defined as solutions of a family of stochastic Volterra equations with a kernel given by the Riesz derivative kernel, and leading coefficients given by a sequence of independent ...

Several theorems on λ–summable series

open access: yesMathematical Modelling and Analysis, 2010
We prove several propositions on λ‐summable series by Cesàro method (C, 1) or by weighted mean methods N, which are also often called Riesz methods P = (R, pn ).

On a new application of quasi power increasing sequences

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2019
In the present paper, absolute matrix summability of infinite series has been studied. A new theorem concerned with absolute matrix summability factors, which generalizes a known theorem dealing with absolute Riesz summability factors of infinite series,

Different adaptive modified riesz mean filter for high-density salt-and-pepper noise removal in grayscale images

open access: yes, 2021
This paper proposes a new filter, Different Adaptive Modified Riesz Mean Filter (DAMRmF), for high-density salt-and-pepper noise (SPN) removal. DAMRmF operationalizes a pixel weight function and adaptivity condition of Adaptive Median Filter (AMF).
