the wiener index $w(g)$ of a connected graph $g$‎ ‎is defined as $w(g)=sum_{u,vin v(g)}d_g(u,v)$‎ ‎where $d_g(u,v)$ is the distance between the vertices $u$ and $v$ of‎ ‎$g$‎. ‎for $ssubseteq v(g)$‎, ‎the {it steiner distance/} $d(s)$ of‎ ‎the vertices of $s$ is the minimum size of a connected subgraph of‎ ‎$g$ whose vertex set is $s$‎. ‎the {it $k$-th steiner wiener index/}‎ ‎$sw_k(g)$ of $g$ ...

The ongoing growth in the volume of scientific literature available today precludes researchers from efficiently discerning the relevant from irrelevant content. Researchers are constantly interested in impactful papers, authors and venues in their respective fields. Moreover, they are interested in the so-called recent “rising stars” of these contexts which may lead to attractive directions fo...

Our aim is to compare the distribution of two stock indices: the Polish WIG20 and the American S&P500. We consider the Closing price of these indices (X) in the years 1994– 2006. The observed values x t (denoting the closing price at day t) were transformed to z t = ln(x t+1 − ln(x t) appropriately. The derived variable Z will be called daily return. We have 2 goals: 1. to compare the daily dyn...

We employ the DEMATEL-based analytic network process (D-ANP) to evaluate the weight of various factors on S&P 500 index futures. The general regression method is employed to prove the result. We then employed grey relational analysis (GRA) to examine predictive power of determinants suggested by 13 experts for fluctuations in S&P 500 index futures. This study yields a number of empirical result...

Abstract Background: In this article "Student to Staff Index" was improved by implying student grades and staff academic ranks in every institute as a new "Standard S. to S. Index". Also "Utilized S. from S. Index" was introduced for controlling and ranking the private universities.  Methods: This index uses the numbers of classes a...

AIMS To predict 5 year survival in patients with uveal malignant melanomas DNA indices were studied. METHODS Using 45 paraffin embedded uveal malignant melanomas, the DNA index and S phase fraction of each tumour were the predictor variables recorded. RESULTS Using the Cox proportional hazards model, aneuploid tumours and tumours which had an S phase fraction greater than 4% were significan...

Today, two classes of indexing methods enjoying wide applicability are the Inverted Index and the Superimposed Coding based Signature File (SC-SF). The former is most efficient in query processing but utilizes extra storage of size comparable to that of the textbase, whereas the latter is most efficient in storage utilization. The present study builds upon the results obtained in previous resea...
