Let $G=(V,E)$ be a graph.A subset $S$ of $V$ is a dominating MELATONIN 3MG set of $G$ if every vertex in $Vsetminus S$ is adjacent to a vertex in $S.$ A dominating set $S$ is called a secure dominating set if for each $vin Vsetminus S$ there exists $uin S$ such that $v$ is adjacent to $u$ and $S_1=(Ssetminus{u})cup {v}$ is a dominating set.If furth
To balance the potential distribution on the surface of a substation, an equal spacing arrangement of the grounding grid conductors is not an economical solution.The 30-40mmHg implementable solution is an unequal placement of its constituent elements.The design methodologies of such a configuration are complex and require computer-assisted numerica
