the reverse degree distance of a connected graph $g$ is defined in discrete mathematical chemistry as [ r (g)=2(n-1)md-sum_{uin v(g)}d_g(u)d_g(u), ] where $n$, $m$ and $d$ are the number of vertices, the number of edges and the diameter of $g$, respectively, $d_g(u)$ is the degree of vertex $u$, $d_g(u)$ is the sum of distance between vertex $u$ and all other vertices of $g$, and $v(g)$ is the ...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
The local boxicity of a graph G, denoted by lbox(G), is the minimum positive integer l such that G can be obtained using intersection k (where k≥l) interval graphs where each vertex appears as non-universal in at most these graphs. Let on n vertices having m edges. Δ denote maximum degree G. We show that, lbox(G)≤213log⁎ΔΔ. lbox(G)∈O(nlogn). lbox(G)≤(213log⁎m+2)m. its product dimension. This...
in a graph g = (v,e), a subset s v is said to be an open packing set if no two vertices of s have a common neighbour in g. the maximum cardinality of an open packing set is called the open packing number and is denoted by rho^o. this paper further studies on this parameter by obtaining some new bounds.
