My aim is show the literature on provide crucial resources relational egalitarianism, which has made equality into central topic contemporary normative political theorizing. The hope that more discriminating detailed picture will egalitarians move beyond discus...

detention rockfill dams are accounted as economically efficient structures for flood control, river bed and banks protection, flow diversion, etc. as the hydraulic behavior of these structures, when are used for flood control, is affected by the depth of water in their porous media, there are interests to predict water surface profile through the body of these structures. in this research, we d...

We give a complete picture of the interaction between Koszul and Ringel dualities for graded standardly stratified algebras (in the sense of Cline, Parshall and Scott) admitting linear tilting (co)resolutions of standard and proper costandard modules. We single out a certain class of graded standardly stratified algebras imposing the condition that standard filtrations of projective modules are...

A comparison is made between the variance of the estimator of the total of a variable obtained from both a simple and a stratified random sampling, in which the sample sizes of some strata are equal to the stratum population size. It is shown that in this case, the advantage of the stratified sample could depend on the sample size. The paper presents inequalities that determine, as a function o...

Spammers intend to increase the PageRank of certain spam pages by creating a large number of links pointing to them. We propose a novel method based on the concept of personalized PageRank that detects pages with an undeserved high PageRank value without the need of any kind of white or blacklists or other means of human intervention. We assume that spammed pages have a biased distribution of p...
