two multivariate calibration methods are compared for the simultaneous chromatographic determination and separation of sulfamethoxazole (smx) and phthalazine (phz) by high performance liquid chromatography (hplc). multivariate calibration techniques such as classical least squares (cls) and inverse least squares (ils) were introduced into hplc to determine the quantification by using uv detecto...

a meshless method namely, discrete least square method (dlsm), is presented in the paper for the solution of free surface seepage problem. in this method computational domain is discredited by some nodes and then the set of simultaneous equations are built using moving least square (mls) shape functions and least square technique. the proposed method does not need any background mesh therefore ...

In many simulation studies the performance of the modeled system is characterized only by mean values of the performance indices. However, the percentiles are more informative in summarizing the performance. Several simultaneous percentiles, presented for example in the form of the boxplot, provide the analyst with better understanding of the system's behaviour. The simultaneous estimation of s...
