A Brief Survey on the two Different Approaches of Fundamental Equivalence Relations on Hyperstructures

open access: yesRatio Mathematica, 2017
Fundamental structures are the main tools in the study of hyperstructures. Fundamental equivalence relations link hyperstructure theory to the  theory of corresponding classical structures. They also introduce new hyperstructure classes.The present paper

A derivative method for minimising total cost in heat exchanger networks through optimal area allocation [PDF]

open access: yes, 2013
This paper presents a novel Cost Derivative Method (CDM) for finding the optimal area allocation for a defined Heat Exchanger Network (HEN) structure and stream data, without any stream splits to achieve minimum total cost. Using the Pinch Design Method (

On Higher Structures

open access: yes, 2015
In this paper we discuss various philosophical aspects of the hyperstructure concept extending networks and higher categories. By this discussion we hope to pave the way for applications and further developments of the mathematical theory of ...

Coupled superconductors and beyond [PDF]

open access: yes, 2012
This paper describes the events leading to the discovery of coupled superconductors, the author's move in the 1970s to a perspective where mind plays a role comparable to matter, and the remarkable hostility sometimes encountered by those who venture ...

On Neutrosophic Canonical Hypergroups and Neutrosophic Hyperrings [PDF]

open access: yesNeutrosophic Sets and Systems, 2014
A neutrosophic hyperstructure is an algebraic structure generated by a given hyperstructure H and an indeterminacy factor I under the hyperoperation(s) of H.

Finite H_v-Fields with Strong-Inverses

open access: yesRatio Mathematica, 2017
The largest class of hyperstructures is the class of H v -structures. This is the class of hyperstructures where the equality is replaced by the non-empty intersection.

Algebraic Hyperstructure of Multi-Fuzzy Soft Sets Related to Polygroups

open access: yesMathematics, 2022
The combination of two elements in a group structure is an element, while, in a hypergroup, the combination of two elements is a non-empty set. The use of hypergroups appears mainly in certain subclasses.

On Isomorphism Theorems of Fn -Polygroups [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2013
In this paper, the notion of fuzzy n-polygroups (Fn -polygroups) is introduced and some related properties are investigated. In this regards, the concepts of normal  F-subpolygroups and homomorphisms of Fn-polygroups are adopted. Also, the quotient of Fn-

Interval valued intuitionistic $(S,T)$-fuzzy $H_v$-submodules

open access: yes, 2006
On the basis of the concept of the interval valued intuitionistic fuzzy sets introduced by K.Atanassov, the notion of interval valued intuitionistic fuzzy $H_v$-submodules of an $H_v$-module with respect to $t$-norm $T$ and $s$-norm $S$ is given and the ...
