On the convergence rates of pairs of adjacent sequences

open access: yesJournal of Numerical Analysis and Approximation Theory, 2020
In this paper we give a suitable definition for the pairs of adjacent (convergent) sequences of real numbers, we present some two-sided estimations which caracterize the order of convergence to its limits of some of these sequences and we give certain ...

On Gradual Borel Summability Method of Rough Convergence of Triple Sequences of Beta Stancu Operators

open access: yesDera Natung Government College Research Journal, 2023
We define the concept of rough limit set of a triple sequence space of beta Stancu operators of Borel summability of gradual real numbers and obtain the relation between the set of rough limit and the extreme limit points of a triple sequence space of ...

Orthogonal families of real sequences [PDF]

open access: yesJournal of Symbolic Logic, 1998
For x, y ϵ ℝω define the inner productwhich may not be finite or even exist. We say that x and y are orthogonal if (x, y) converges and equals 0.Define lp to be the set of all x ϵ ℝω such thatFor Hilbert space, l2, any family of pairwise orthogonal sequences must be countable.

On certain Banach spaces of difference sequences of fuzzy real numbers [PDF]

open access: yesMaejo International Journal of Science and Technology, 2014
Some sets of difference sequences of fuzzy real numbers which have Banach subspaces are introduced and investigated. Further, it is shown that these subspaces are isometric with some subsets of the sets of null, convergent and bounded sequences of fuzzy

Ideal-quasi-Cauchy sequences [PDF]

open access: yes, 2012
An ideal $I$ is a family of subsets of positive integers $\textbf{N}$ which is closed under taking finite unions and subsets of its elements.

Design of doubly-complementary IIR digital filters using a single complex allpass filter, with multirate applications [PDF]

open access: yes, 1986
It is shown that a large class of real-coefficient doubly-complementary IIR transfer function pairs can be implemented by means of a single complex allpass filter.

Sequence of operations for real‐time control of microgrids and networked microgrids

open access: yesIET Renewable Power Generation, 2022
Microgrids (MGs) provide a potential solution to accommodating renewable and distributed energy resources (DERs). MGs and the networked form of MGs, that is, networked MGs or NMGs, have received significant attention in the past two decades.

Empirical Likelihodd Methods for an AR(1) process with ARCH(1) errors [PDF]

open access: yes, 2006
For an AR(1) process with ARCH(1) errors, we propose empirical likelihood tests for testing whether the sequence is strictly stationary but has infinite variance, or the sequence is an ARCH(1) sequence or the sequence is an iid sequence.
