Six mathematical models were selected for the fitting and regression of particle size distribution (PSD) (α,Z)-2-amino-α-(methoxyimino)-4-thiazole-ethanethioic acid S-2-benzothiazolyl ester (MAEM). The goodness-of-fit was evaluated by comparing evaluation indexes such as R2, Akaike's information criterion (AIC), root mean square error (RMSE). top three further applied compared PSD MAEM produced...

one of the models that can be used to study the relationship between boolean random sets and explanatory variables is growth regression model which is defined by generalization of boolean model and permitting its grains distribution to be dependent on the values of explanatory variables. this model can be used in the study of behavior of boolean random sets when their coverage regions variation...

The Weibull distribution is widely employed in several areas of engineering because it is an extremely flexible distribution with different shapes. Moreover, it can include characteristics of several other distributions. However, successful usage of Weibull distribution depends on estimation accuracy for three parameters of scale, shape and location. This issue shifts the attentions to the requ...

reconnaissance drought index (rdi) is based on fitting a log-normal distribution to the ratio of precipitation to evapotranspiration (eto) values in selected periods. in this index value of eto were calculated based on mean temperature by thorenth-waite (th) method. th method, may underestimated eto values comparing to the actual in arid and semi arid regions. the log-normal distribution may no...
