A STUDY ON VERTEX ODD MEAN & VERETX EVEN MEAN LABELING OF SOME GRAPHS
Authors: C. Vimala, M. Gayathri
Abstract
A graph πΊ with π vertices and π edges is a mean graph if there is an injective function f from the vertices of πΊ to {0, 1, 2, β¦ , π} such that when each edge π’π£ is labeled with ΰ―(ΰ―¨)ΰ¬Ύΰ―(ΰ―©)ΰ¬Ά if π(π’) + π(π£) is even and ΰ―(ΰ―¨)ΰ¬Ύΰ―(ΰ―©)ାଡଢ if π(π’) + π(π£) is odd, then the resulting edges are distinct. The graph which admits the vertex odd mean labeling and vertex even mean labeling are called as vertex odd mean and vertex even mean graph respectively. In this paper we investigate vertex odd and vertex even mean labeling of the graphs πΰ―‘ + ππΰ¬·, ππΆΰ¬Έ + 2πΰ¬Ά and ππΆΰ¬Έ + πΰ¬Έ.

Abstract
Now-a-days, Wireless sensor networks play an important role in a wide range of applications. All the sensor nodes equipped with non-replaceable batteries for monitoring the desired region by fixed topology. By using WSNs everywhere, it becomes the main key of the big data in the emerging world.

Authors: Sudhir Kumar pundir, Deepak kapil, Rimple pundir
Abstract
The effect of couple stress on thermal instability of visco-elastic Rivlin-Ericksen nanofluid layer through a porous medium is investigated for more realistic boundary conditions. By applying Perturbation method, Normal mode technique, the effects of the various physical parameters of the system namely Lewis number, modified diffusivity ratio, nano particle Rayleigh number and couple stress on the stationary convection have been investigated both analytically and graphically. The Lewis number, modified diffusivity ratio, nano particle Rayleigh number and couple stress are found to have stabilizing effect on stationary convection.
