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...

The main properties of the observed extrasolar planets are reviewed with respect to their relevance to the formation scenario of planetary systems. Results of numerical computations of embedded planets in viscously evolving disks are presented. Emphasis is given to the accretion and migration process. New calculations on inviscid disks are shown. The second part of the talk concentrates on reso...

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...

ABSTRACT Secular oscillations in multiplanet systems can drive chaotic evolution of a small inner body through non-linear resonant perturbations. This ‘secular chaos’ readily pushes the to an extreme eccentricity, triggering tidal interactions or collision with central star. We present numerical study secular chaos two planets and test particles using ring-averaging method, emphasis on relation...
