the concept of  -semihyperring is a generalization of semiring, a generalization of semihyperring and a generalization of      -semiring. since the theory of ideals plays an important role in the theory of  - semihyperring, in this paper, we will make an intensive study of the notions of noetherian, artinian, simple and   regular      -semihyperrings. the bulk of this paper...

In this paper, real options theory is utilized to evaluate the effect of uncertain electricity and CO2 costs on speculation conduct. Methodologically, the allegiance of the newspaper in this appreciation is that uncertainty is not just stopped down as far as stochastic processes and their fluctuation, additionally as far as expected and acknowledged procedures, i.e. the procedures, w...

the aim of this paper is to introduce and study set- valued homomorphism on lattices and t-rough lattice with respect to a sublattice. this paper deals with t-rough set approach on the lattice theory. the result of this study contributes to, t-rough fuzzy set and approximation theory and proved in several papers. keywords: approximation space; lattice; prime ideal; rough ideal; t-rough set; set...

This article addresses the concept of authenticity, a characteristic of late modern Western culture. This characteristic is viewed by some as an ideal and by others as a root of the problems inherent within Western culture. After discussing various viewpoints, the author supports the idea that authenticity should not be totally accepted or rejected and sets forth a proposal based on the so-call...

Abstract In this theoretical paper, we consider the notion of semantic competence and its relation to general language understanding—one most sough-after goals Artificial Intelligence. We come back three main accounts involving (a) lexical knowledge; (b) truth-theoretic reference; (c) causal chains in use. argue that all are needed reach a meaning artificial agents suggest they can be combined ...

in this paper, presenting two simple methods for ranking of efficient dmus in dea models that included to add one virtual dmu as ideal dmu and is using the additive model. note that, we use an ideal point just for comparing efficient dmus with. although these methods are simple, they have ability for ranking all efficient dmus, extreme points and the others, also they are capable of ranking the...
