Linear index coding can be formulated as an interference alignment problem, in which precoding vectors of the minimum possible length are to be assigned to the messages in such a way that the precoding vector of a demand (at some receiver) is independent of the space of the interference (non sideinformation) precoding vectors. An index code has rate 1 l if the assigned vectors are of length l. ...

to evaluate the effect of water stress on yield and water use efficiency (wue) of lallemantia sp, an experiment was conducted as split plot factorial in randomized complete block design with three replications in the field of medicinal plants research center of shahed university, tehran in 1390-91. the first factor was irrigation system including 40 and 60 percent depletion of available soil wa...

in order to identify and determine weed population in sugar beet fields, 92 fields from five counties of kermanshah province in iran were selected and evaluated at two growing stages (early may and late september) in 2014. the weed population indices were calculated by counting the number of weeds separated on othe basis of genus and species. for all fields, the latitude, longitude and altitude...

let $a$ be a non-trivial abelian group and $a^{*}=asetminus {0}$. a graph $g$ is said to be $a$-magic graph if there exists a labeling$l:e(g)rightarrow a^{*}$ such that the induced vertex labeling$l^{+}:v(g)rightarrow a$, define by $$l^+(v)=sum_{uvin e(g)} l(uv)$$ is a constant map.the set of all constant integerssuch that $sum_{uin n(v)} l(uv)=c$, for each $vin n(v)$,where $n(v)$ denotes the s...

In this talk we present some results concerning the interpolation of discontinuous functions. First we consider an index of convergence associated to converging subsequences of a general sequence of real numbers (x n) n≥1. Namely, if L ∈ R, the index of convergence of (x n) n≥1 to L is defined by The definition can be extended to the cases L = ±∞ and also to the case where A ⊂ R. In the case wh...

The goal of this paper is to determine the braid index of two types of complicated DNA polyhedral links introduced by chemists and biologists in recent years. We shall study it in a more broad context and actually consider so-called Jaeger's links (more general Traldi's links) which contain, as special cases, both four types of simple polyhedral links whose braid indexes have been determined an...
