Given the concept of reliability-based design (RBD) and the growing risk management trend in geotechnical engineering, proper understanding and quantification of uncertainties are very important. The complexity of methods and a large volume of calculations of probabilistic design methods are the most critical reasons for civil engineers not to be comfortable using these approaches. In this rese...
In order to study the effect of traits related to baking quality of bread wheat, an experiment was carried out by six bread wheat genotypes (as parents) and their15 F1progeny using randomized complete block design with three replications in Kermanshah, Iran during crop season 2010- 2011. In this study 14 traits attributes baking quality bread wheat were evaluated. The analysis of variance was i...
In this article we report the results of an investigation on the stability of solitary solutions to the Cubic-Quintic Coupled Nonlinear Schr ö dinger Equations.Using the theory of linear operators (here,2×2 matrics), we show that under a perturbation ui→ui + δui(δui= (αi(T) + ibi(T))eµδ)(i=1,2) the solitary solutions are stable. Moreover,we include the perturbation into the corresponding Hami...
genetic diversity is essential in the implementation of breeding programs. in order to determine genetic diversity, factor analysis and heritability of yield and some morphological traits, 20 strawberry cultivars were studied at the agricultural station of kurdistan research center using a randomized complete block design with three replications. morphological characteristics such as number of ...
the seasonal and diurnal variations in the incidence of hypertension, cerebrovascular accident, coronary heart disease were well documented, but the relation between season and daytime on the onset of aneurysmal subarachnoid hemorrhage (asah) was a subject of controversy. in the present study we aimed to evaluate the role of season of year and diurnal changes on the onset of asah. the time was ...
This paper introduces a new paradigm for minimax game-tree search algorithms. MT is a memory-enhanced version of Pearl’s Testprocedure. By changing the way MT is called, a number of best-first game-tree search algorithms can be simply and elegantly constructed (including SSS*). Most of the assessments of minimax search algorithms have been based on simulations. However, these simulations genera...

This research was conducted in order to determine the relationship between grain yield and yield components, using 30 common bean varieties in a randomized complete block design with four replications at the Agricultural filed faculty of Agriculture,Tehran university In this study 18 traits were assessed on 10 random plants from each plot. The result showed that there were significant differe...
Salvia L. genus has antibacterial, antioxidant, antidiabetic and culinary properties. This genus consists of 55 species including 17 endemic ones in Iran. Out crossing and widespread distribution of Salvia L. genus plants have led to great impact on their morphological variation of ecotypes. This study was conducted for investigating morphological variation as well as characters relationsh...
