To check the financial stability, it is important to alarm the possibility of future potential financial crisis. In the literature, the early warning system (EWS) is designed to warn the occurrence of a financial crisis ...

Dombi family of t-norms includes a parametric family of continuous strict t-norms, whose members are increasing functions of the parameter. This family of t-norms covers the whole spectrum of t-norms when the parameter is ...

Let $G=(V,E)$ be a graph. A doubleRoman dominating function (DRDF) on $G$ is a function$f:Vto{0,1,2,3}$ such that for every vertex $vin V$if $f(v)=0$, then either there is a vertex $u$ adjacent to $v$ ...

The edge-tenacity $T_e(G)$ of a graph G was defined asbegin{center} $T_e(G)=displaystyle min_{Fsubset E(G)}{frac{mid Fmid +tau(G-F)}{omega(G-F)}}$end{center}where the minimum is taken over all ...

In real world, organization's requirements for high performance resources and high capacity storage devices encourage them to use resources in public clouds. While private cloud provides security and low cost ...

A new algorithm for point-inclusion test in convex polygons is introduced. The proposed algorithm answers the point-inclusion test in convex polygons in $mathcal{O}(log n)$ time without any preprocessing and with $mathcal{O}(n)$ ...
