The aim of this paper is to present exact formulas for the vertex and edge

PI indices of the generalized hierarchical product of graphs. As a consequence of our

results, these indices were computed for some chemical graphs....

We investigated the role of culture in processing hierarchical syntactic structures in music. We examined whether violation of nonlocal dependencies manifest in event related potentials (ERP) for Western and Iranian excerpts by recording EEG while...

districts are key factors in productivity growth. In this work, we apply a spatial Bayes model that uses hierarchical techniques during the three terms. The productivity clustering map is able to capture such patterns as the high productivity area...

, the coherent generators are determined using a pattern recognition technique called hierarchical clustering method. In this method, firstly, rotor angles of the generators are obtained based on transient stability technique which are calculated by solving state...
