On the convergence properties of sampling Durrmeyer‐type operators in Orlicz spaces

open access: yesMathematische Nachrichten, Volume 296, Issue 2, Page 588-609, February 2023., 2023
Abstract Here, we provide a unifying treatment of the convergence of a general form of sampling‐type operators, given by the so‐called sampling Durrmeyer‐type series. The main result consists of the study of a modular convergence theorem in the general setting of Orlicz spaces Lφ(R)$L^\varphi (\mathbb {R})$.

Mathematical models for the improvement of detection techniques of industrial noise sources from acoustic images

open access: yesMathematical Methods in the Applied Sciences, Volume 44, Issue 13, Page 10448-10459, 15 September 2021., 2021
In this paper, a procedure for the detection of the sources of industrial noise and the evaluation of their distances is introduced. The above method is based on the analysis of acoustic and optical data recorded by an acoustic camera. In order to improve the resolution of the data, interpolation and quasi interpolation algorithms for digital data ...
