black saxaul (haloxylon aphyllum) is one of the best options for rehabilitating drought affected desert lands. the species is remarkably adapted to the central dry environment ofiran and a major source of raising pasture productivity of the areas. progenies of 25 randomly selected black saxaul trees from four populations of the species were studied in a randomized complete block design with thr...

conclusions some results of the correlation coefficients are not the same with visualization. the reason may be due to the small number of data. materials and methods in the foundation-application study, we constructed two-way gene networks using nonparametric methods, such as spearman’s rank correlation coefficient and blomqvist’s measure, and compared them with pearson’s correlation coefficie...

We have investigated an intensity-based image registration technique using a robust correlation coefficient as a similarity measure. The proposed method has an advantage over the ordinary correlation coefficient since it reduces the effect of “outlier” image intensity values. For the application of image registration to radiotherapy or image-guided surgery, there may be outlier samples due to t...

precipitation is one of the hydrological processes that play an important role in controlling water resources management. shortage of rain causes some problems such as lack of drinking water. due to the importance of the issue of water shortage, using modern methods to predict hydrological processes will play an important role in planning and management of water resources. therefore, in this st...
