the amount of meritocracy system establishment in the government agencies of ahvaz is assessed in this study. meritocracy is a system in which the job benefits and situations are given to the people just on the basis of merit and not based on the gender, social class, ethnicity or wealth. statistical society is the employers of government organizations of ahvaz (n=10377) and the volume of sampl...

In this paper, we construct two fuzzy sets using the notions of level subsets and strong level subsets of a given fuzzy set in a ring R. These fuzzy sets turn out to be identical and provide a universal construction of a fuzzy ideal generated by a given fuzzy set in a ring. Using this construction and employing the technique of strong level subsets, we provide the shortest and direct fuzzy set ...

In any graph $G$, the domination number $\gamma(G)$ is at most independence $\alpha(G)$. The \emph{Inverse Domination Conjecture} says that, in isolate-free there exists pair of vertex-disjoint dominating sets $D, D'$ with $|D|=\gamma(G)$ and $|D'| \leq \alpha(G)$. Here we prove that this statement true if upper bound $\alpha(G)$ replaced by $\frac{3}{2}\alpha(G) - 1$ (and $G$ not a clique). We...

In this paper we develop a boundary $\varepsilon$-regularity theory for optimal transport maps between bounded open sets with $C^{1,\alpha}$-boundary. Our main result asserts sharp $C^{1,\alpha}$-regularity of at the in form linear estimate under certain assumptions: The quantitative assumptions are that local nondimensionalized cost is small and boundaries locally almost flat $C^{1,\alpha}$. m...
