Three IndicesCalculationof Certain Crown Molecular Graphs
Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2014, Vol 9, Issue 6
Abstract
As molecular graph invariant topological indices, harmonic index, zeroth-order general Randic index and Co-PI index have been studied in recent years for prediction of chemicalphenomena. In this paper, we determine the harmonic index, zeroth-order general Randic index andCo-PI indexof certain r-crown molecular graphs.

Restricted Three- Body Problem in Parabolodial Coordinate System
In this paper, the equations of motion for the spatial circular restricted three- body problem in sidereal parabolodial coordinates system were established. Initial value procedure that can be used to compute both the pa...
Matrices of inversions for permutations: Recognition and Applications
This work provides a criterion for a binary strictly upper triangle matrices to be a matrix of inversions for a permutation. It admits an invariant matrices for permutations to being well recognizable. Then it provides a...
A New Five Parameter Lifetime Distribution: Properties and Application
This paper deals with a new generalization of the Weibull distribution. This distribution is called exponentiated exponentiated exponential-Weibull (EEE-W) distribution. Various structural properties of the new probabili...
Stochastic Analysis of Two Non-identical Unit Parallel System Incorporating Waiting Time and Preventive Maintenance
