in this paper, a novel topological index, named m-index, is introduced based on expanded form of the wiener matrix. for constructing this index the atomic characteristics and the interaction of the vertices in a molecule are taken into account. the usefulness of the m-index is demonstrated by several qspr/qsar models for different physico-chemical properties and biological activities of a large...

This paper presents a Generalizability Theory (GT) analysis of the dependability of measures obtained using the Seevers, Dormody and VanLeeuwen (1998) SET instrument. The analysis of Seevers , et al. (1998) data suggests that both student means and class means are sufficiently reliable measuresfor most purposes. These data are used to illustrate the GT estimation of reliabilities for both stude...

the first geometric-arithmetic index was introduced in the chemical theory as the summationof 2 du dv /(du  dv ) overall edges of the graph, where du stand for the degree of the vertexu. in this paper we give the expressions for computing the first geometric-arithmetic index ofhexagonal systems and phenylenes and present new method for describing hexagonal systemby corresponding a simple graph...

Of increasing interest to the educational assessment researchers is the reliability of scores obtained by various measurement procedures like tests, rating scales, surveys, and observation forms. Traditional methods of reliability based on Classical Test Theory (CTT) consider only one source of measurement errors. Generalizability Theory (GT) extends CTT by providing a flexible and practical fr...

An effective theory for the soft field modes in hot QCD has been obtained recently by integrating out the field modes of momenta of order T and gT . The mean hard particle distribution obeys a transport equation with a collision term. The scale that comes out for the soft field is gT ln 1/g . Explicit solutions have been written for the linearized mean field distribution and for the polarizatio...

The development of sociological approach to the study of translation makes it possible for the researchers to adopt different methodology to develop new theoretical formulations and concepts. These formulations are arrived at through the interaction with those being studied through the interpretation of real social world and meanings of the participants involved in the translation/social event....

the main aim of this paper is to extend the recently developed methods for calculating the buckling loads of planar symmetric frames to include the effect of semi-rigidity of the joints. this is achieved by decomposing a symmetric model into two submodels and then healing them in such a manner that the ::::union:::: of the eigenvalues of the healed submodels result in the eigenvalues of the ent...
