A Split plot experiment based on randomized complete block design (RCBD) with three replications was conducted in 2012,Treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (Sardari, Rijav, Biseton and Rashid) as the second factor. Plant characteristics such as plant height, length o...

The inverse Weibull model was developed by Erto [10]. In practice, the unknown parameters of the appropriate inverse Weibull density are not known and must be estimated from a random sample. Estimation of its parameters has been approached in the literature by various techniques, because a standard maximum likelihood estimate does not exist. To estimate the unknown parameters of the three-param...

Brooks’ Theorem states that a connected graph G of maximum degree ∆ has chromatic number at most ∆, unless G is an odd cycle or a complete graph. A result of Johansson shows that if G is triangle-free, then the chromatic number drops to O(∆/ log∆). In this paper, we derive a weak analog for the chromatic number of digraphs. We show that every (loopless) digraph D without directed cycles of leng...

In regression analysis for deriving scaling laws in the context of fusion studies, usually standard regression methods have been applied, of which ordinary least squares (OLS) is the most popular. However, concerns have been raised with respect to several assumptions underlying OLS in its application to fusion data. More sophisticated statistical techniques are available, but they are not widel...

. Ordinary least squares, two-stage squares and the NISE estimator are applied to three data sets involving equations from microeconomics macroeconomics. The focus is on simultaneity bias in linear ability of other estimators mitigate bias.

—Calliphlox iridescens Gould, 1860 is hypothesized to be a hybrid between Calliphlox amethystina and Chlorostilhon aureoventris. The hybrid, collected at Nova Friburgo, Rio de Janeiro. Brazil, exhibits a blended mosaic of plumage characters of the presumed parental species. External measurements of the hybrid fall between the character means of the parental species and approach the values expec...

When using methods for recovering the least squares optimal pose registration parameters between a model and an image suite construc tion of the feature correspondences is key In clusion of outliers in the correspondence set can severly deteriorate the performace and delity of these pose coregistration estimation algo rithms We consider the use of median lter ing in the construction of consiste...
