Twenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications. Eight drought tolerance indices including stability tolerance index, mean productivity (MP), geometric MP, harmonic ...

Let $G$ be a graph with vertex set $V(G)$ and edge set $E(G)$, and let $d_u$ denote the degree of vertex $u$ in $G$. The Randi'c index of $G$ is defined as${R}(G) =sum_{uvin E(G)} 1/sqrt{d_ud_v}.$In this paper, we investigate the relationships between Randi'cindex and several topological indices.

a two years (2006–2007 and 2007-2008) experiment was conducted at national salinity research center, yazd, to evaluate salt-tolerant genotypes of brassica napus, b. rapa and b. juncea. to screen genotypes in the first growing season, 58 genotypes were grown under two irrigation water salinity levels of 2 and 12 ds m-1 in an augmented randomized complete block design with six replicated checks. ...

background: in vivo dosimetry is a method for estimation of overall error in the delivered dose to the patients at the end of radiotherapy process. in this research, two methods for target dose calculation were evaluated on midline and central axis of photon beams in in vivo dosimetry of thorax fields. materials and methods: entrance and exit doses for anterior and lateral fields of thorax were...

In this paper, we consider fractional Liu process. First, the membership functions, expected values and variances of arithmetic and geometric fractional Liu process are given. Then we suppose that stock price follows geometric fractional Liu process and formulate fractional Liu’s stock model. Based on this model, European option pricing formulas are obtained.

We present our exact numerical perturbation technique for eliminating degeneracies occurring in geometric modeling processes. Consider a geometric modeler that performs a set of geometric operations (e.g. CSG-based Boolean operations). We would like to make the geometric modeler “robust” with respect to degeneracies, meaning that it will not crash. Our approach achieves many of the same results...

The article shows how two choices are possible whenever computing the geometric mean, and repetition of this process can in general yield 2-to-the power N different values when compounded first steps evaluation arithmetic-geometric mean. This happens not only simple AGM involved computation complete elliptic integral kind, but also analogous methods for incomplete integrals second kind.
