We define here a standard candle to determine the distance of clusters of galaxies and to investigate their peculiar velocities by using the n rank galaxy (magnitude mn). We address the question of the universality of the luminosity function for a sample of 28 rich clusters of galaxies (cz≃20000 km.s) in order to model the influence on mn of cluster richness. This luminosity function is found t...

In this article, the structural, elastic, electronic, and magnetic characteristics of both regular inverse Heusler alloys, Sc2TiAl Sc2TiSi, were investigated using a full-potential, linearized augmented plane-wave (FP-LAPW) method, within density functional theory. The optimized structural parameters determined from minimization total energy versus volume unit cell. band structure DOS calculati...

Abstract Anti-perovskites A 3 SnO (A = Ca, Sr, and Ba) are an important class of materials due to the emergence Dirac cones tiny mass gaps in their band structures originating from intricate interplay crystal symmetry, spin-orbit coupling, overlap. This provides exciting playground for modulating electronic properties two-dimensional (2D) limit. Herein, we employ first-principles density functi...

Application-level multicast trees built using reversepath forwarding (RPF) on overlay network routing paths are a useful mechanism for scalable information dissemination. One major drawback of this approach is that nodes that are not subscribers to a multicast group can still be required to forward traffic for that group if they happen to lie on an overlay routing path between a subscriber and ...

The stability, electronic structure, optical and thermoelectric properties of Te-doped BaTiO3 are investigated by first-principal calculation based on the density functional theory Boltzmann transport implemented in WIEN2K BoltzTraP simulation program. This study is carried out applying LDA + TB-mBJ potential. Formation energy each doped structure calculated to examine stability feasibility syn...
