How good are MatLab, Octave and Scilab for Computational Modelling? [PDF]
arXiv.org, 2012 In this article we test the accuracy of three platforms used in computational modelling: MatLab, Octave and Scilab, running on i386 architecture and three operating systems (Windows, Ubuntu and Mac OS). We submitted them to numerical tests using standard

A new approach for data transmission system on topological surfaces [PDF]
, 2012 This work introduces a new data transmission system in which the main blocks, coding, modulation and channel are designed on a Riemannian manifolds. An intrinsic algebraic structure to the manifolds (surface), the homology group will be used to compose ...

On Fuzzy Ideals of Subtraction Algebras
Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2013 : In this paper, we introduce the notion of fuzzy interior ideal, fuzzy bi-ideal, intuitionistic fuzzy interior ideal and intuitionistic fuzzy bi-ideal of a subtraction semigroup.

Stack-sorting for Coxeter groups [PDF]
, 2022 Given an essential semilattice congruence \(\equiv\) on the left weak order of a \linebreak Coxeter group \(W\), we define the Coxeter stack-sorting operator \({\bf S}_\equiv:W\to W\) by \({{\bf S}_\equiv(w)=w\big(\pi_\downarrow^\equiv(w)\big)^{-1 ...

On Various 2-absorbing prime ideals in non commutative rings
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023 In this paper we analyze strongly 2-absorbing prime ideals (shortly strongly 2-API), strongly 2-absorbing weak prime ideals (shortly strongly 2-AWPI) and 2-absorbing weak prime ideals (shortly 2-AWPI) in a non-commutative ring, which represent ...

Some operations on lattice implication algebras
International Journal of Mathematics and Mathematical Sciences, Volume 27, Issue 1, Page 45-52, 2001., 2001 We introduce the concept of a ⊗‐closed set and a ⊗‐homomorphism in lattice implication algebras, and we discuss some of their properties. Next, we introduce the fuzzy implicative filter and obtain equivalent conditions. Finally, we discuss the operation ⊗, fuzzy filters and fuzzy implicative filters.

CONSTRUCTION OF COMPLEX NESTED IDEAL LATTICES FOR COMPLEX-VALUED CHANNEL QUANTIZATION
, 2018 In this work we develop a new algebraic methodology which quantizes complex-valued channels in order to realize interference alignment (IA) onto a complex ideal lattice.

Fantastic filters of lattice implication algebras
International Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 4, Page 277-281, 2000., 2000 The notion of a fantastic filter in a lattice implication algebra is introduced, and the relations among filter, positive implicative filter, and fantastic filter are given. We investigate an equivalent condition for a filter to be fantastic, and state an extension property for fantastic filter.

Weak-hyperlattices derived from fuzzy congruences
Discussiones Mathematicae - General Algebra and Applications, 2017 In this paper we explore the connections between fuzzy congruence relations, fuzzy ideals and homomorphisms of hyperlattices. Indeed, we introduce the concept of fuzzy quotient set of hyperlattices as it was done in the case of rings [19].

Aggregating Fuzzy Binary Relations and Fuzzy Filters
Discussiones Mathematicae - General Algebra and Applications, 2018 The main goal of this paper is to investigate the aggregation of diverse families of binary fuzzy relations, fuzzy filters, and fuzzy lattices. Some links between these families and their images via an aggregation are explored.
