The neighborhood polynomial of graph $G$ is the generating function for number vertex subsets which vertices have a common neighbor in $G$. In this paper, we investigate behavior under several operations. Specifically, provide an explicit formula obtained from given by attachment. We use result to propose recursive algorithm calculation polynomial. Finally, prove that can be found polynomial-ti...

aim and background: complex nature of children`s affectionate problems requires assessment and usage of modern treatments. the present study aimed to investigate the effects of attachment-based therapy on depression symptoms in girl students of primary school who had attachment problems. methods and materials: this study was an empirical plan with pretest-posttest, follow up and control group. ...

Neighbor attachment is the process of establishing links between nodes that on the physical layer are visible to each other. In ad-hoc and sensor networks many strategies can be followed to connect to adjacent nodes. A simple scenario would be to consider all nodes within the transmission range of a node as its neighbors. More sophisticated scenarios can establish neighborhood relations with a ...
