In this paper, we calculate the eccentric connectivity index and the eccentricity sequence of two infinite classes of fullerenes with 50 + 10k and 60 + 12k (k in N) carbon atoms.

Let G be a connected graph. The eccentricity of path P, denoted by eccG(P), is the maximum distance from P to any vertex in G. In Central (CP) problem, our aim find minimum eccentricity. This problem was introduced Cockayne et al., 1981, study different centrality measures on graphs. They showed that CP can solved linear time trees, but it known NP-hard many classes graphs such as chordal bipar...

5 To be submitted to Paleoceanography. The accuracy of geologic chronologies can, in principle, be improved through 6 orbital tuning, the systematic adjustment of a chronology to bring the as-7 sociated record into greater alignment with an orbitally derived signal. It would 8 be useful to have a general test for the success of orbital tuning, and one pro-9 posal has been that eccentricity ough...

To investigate the relationship between reaction time (RT), stimulus intensity and visual field eccentricity. We generated frequency of seeing (FOS) curves and measured RTs by testing 10 perimetrically experienced normal subjects with a Humphrey perimeter controlled by a custom program. Subjects were tested from 10 degrees to 50 degrees eccentricity along the nasal horizontal meridian in 10 deg...

Abstract Analogues to multiplicative Zagreb indices in this paper two new type of eccentricity related topological index are introduced called the first and second multiplicative Zagreb eccentricity indices and is defined as product of squares of the eccentricities of the vertices and product of product of the eccentricities of the adjacent vertices. In this paper we give some upper and lower b...

A novel analysis for a new type of variable reluctance resolvers (VR-Resolvers) with toroidal windings based on the magnetic equivalent circuit (MEC) method is presented in this work. Different cases including various configurations as well different rotor structures are considered order to investigate performance resolver precisely. The position error both healthy and eccentric studied by flex...

Inhibition of return (IOR) as an indicator of attentional control is characterized by an eccentricity effect, that is, the more peripheral visual field shows a stronger IOR magnitude relative to the perifoveal visual field. However, it could be argued that this eccentricity effect may not be an attention effect, but due to cortical magnification. To test this possibility, we examined this eccen...
