River bed sand and gravel are utilized more than mountain materials due to their availability and closeness to the transit roads and sites of usage. Excessive and non-technical extraction of gravel and sand bring a kind of interference in them, leading to many negative consequences. Therefore, presenting solutions to reduce these impacts and infilling mining pits are essential. In this researc...

Probabilistic graphical models allow us to encode a large probability distribution as composition of smaller ones. It is oftentimes the case that we are interested in incorporating model idea some these distributions likely be similar one another. In this paper provide an information geometric approach on how incorporate and see it allows reinterpret already existing models. Our proposal relies...

The spectral closeness of a graph G is defined as the radius matrix , whose ( u v )-entry for vertex and 2 − d u,v ) if ≠ 0 otherwise, where distance between in . residual nontrivial minimum subgraphs with one deleted. We propose local grafting operations that decrease or increase determine those graphs uniquely minimize and/or maximize some families graphs. also discuss extremal properties clo...

Real technological, social and biological networks evolve over time. Predicting their future topology has applications to epidemiology, targetedmarketing, network reliability and routing in ad hoc and peer-to-peer networks. The key problem for such applications is usually to identify thenodes thatwill be inmore important positions in the future. Previous researchers had used ad hoc prediction f...

One of the most important research topics about complex networks
 is examination their vulnerability. Therefore, there are many studies
 in literature analyzing robustness and reliability using graph theoretical parameters. Among these parameters, centrality
 parameters play an role.The closeness its derivatives
