drought stress is one of the most important dangers for increasing the yield and good production of crops in iran and the world. to evaluate the genetic diversity of rapeseed genotypes, identifying the drought resistance indices and drought tolerant genotypes, 16 genotypes were tested in a randomized complete block design (rcbd) with three replications and two different water regimes (irrigated...

Geometric graph mining has bees identified as a need in many applications. This technique detect patterns with some tolerance under a geometric transformation. To meet this need, some graph miners have been developed for detecting frequent geometric subgraphs. However, there are few works for applying this kind of geometric patterns as feature for classification tasks. In this paper, a new geom...

This paper reports a complete system for modeling, representation, and validation of geometric tolerances, using feature-based approach from boundary representation (B-Rep) based solid models. The utility of feature based representation scheme for representing Geometric Dimensioning and Tolerancing (GDT) information in geometric models is highlighted. Explicit information from B-Rep is culled u...

breeding for environmental stress is one of the most important goals in plant breeding. among stresses, drought stress has high influencing on limitation of wheat production. so, in order to find the best drought tolerant genotypes, 24 genotypes were planted in three separate experiments in ardebil: one with optimum irrigation (control), another with water stress at pre-anthesis stage and the o...

current study aimed at determining the most reliable drought tolerant criteria for identification of sugar beet genotypes. a split plot design based on randomized complete block design with three replications was applied at motahari research station, karaj, iran in 2012. two irrigation treatments including normal irrigation after 80-90 mm and irrigation after 270 mm evaporation (stress conditio...
