e-core of double sequences [PDF]

open access: yesActa Mathematica Hungarica, 2014
Boos, Leiger and Zeller [1,2] defined the concept of e-convergence. In this paper we introduce the concepts of e-limit superior and inferior for real double sequences and prove some fundamental properties of e-limit superior and inferior. In addition to these results we define e-core for double sequences. Also, we show that that if A is a nonnegative \(

The Hilbert Space of Double Fourier Coefficients for an Abstract Wiener Space

open access: yesMathematics, 2021
Fourier series is a well-established subject and widely applied in various fields. However, there is much less work on double Fourier coefficients in relation to spaces of general double sequences.

A zinc finger protein array for the visual detection of specific DNA sequences for diagnostic applications. [PDF]

open access: yes, 2010
The visual detection of specific double-stranded DNA sequences possesses great potential for the development of diagnostics. Zinc finger domains provide a powerful scaffold for creating custom DNA-binding proteins that recognize specific DNA sequences ...

Almost Linear Complexity Methods for Delay-Doppler Channel Estimation [PDF]

open access: yes, 2013
A fundamental task in wireless communication is channel estimation: Compute the channel parameters a signal undergoes while traveling from a transmitter to a receiver.

Korovkin Type Approximation Theorem for Functions of Two Variables Through αβ−Statistical Convergence

open access: yesJournal of Mathematical Sciences and Modelling, 2019
In this paper, we introduce the concepts of αβ−statistical convergence and strong αβ− summability of double sequences and investigate the relation between these two new concepts. Moreover, statistical convergence and αβ− statistical convergence of double

On I θ 2 $\mathcal{I}_{{\theta}_{2}}$ -convergence in fuzzy normed spaces

open access: yesJournal of Inequalities and Applications, 2020
In this study, first, lacunary convergence of double sequences is introduced in fuzzy normed spaces, and basic definitions and theorems about lacunary convergence for double sequences are given in fuzzy normed spaces.

Double Sequences and Limits

open access: yesFormalized Mathematics, 2013
Summary Double sequences are important extension of the ordinary notion of a sequence. In this article we formalized three types of limits of double sequences and the theory of these limits.

Regularly ideal invariant convergence of double sequences

open access: yesJournal of Inequalities and Applications, 2021
In this paper, we introduce the notions of regularly invariant convergence, regularly strongly invariant convergence, regularly p-strongly invariant convergence, regularly ( I σ , I 2 σ ) $(\mathcal{I}_{\sigma },\mathcal{I}^{\sigma }_{2})$ -convergence ...

Design of an analog/digital truly random number generator [PDF]

open access: yes, 1990
An analog-digital system is presented for the generation of truly random (aperiodic) digital sequences. This model is based on a very simple piecewise-linear discrete map which is suitable for implementation using monolithic analog sampled-data ...

Asymptotically double lacunry equivalent sequences defined by Orlicz functions

open access: yesActa Scientiarum: Technology, 2014
This paper presents the following definition which is natural combition of the definition for asymptotically equivalent and Orlicz function. The two nonnegative double sequences x=(x_{k,l}) and y=(y_{k,l}) are said to be M-asymptotically double ...
