| Abstract: | In this paper, the change in scattering light intensity along with the blending time was analyzed by the Back Small Angle Laser scattering (BSALS) method. An Auto Regressive Moving Average model (ARMA(p,q)) was selected on Akaile's Information Criterion (AIC), BIC and MSE. The model parameters were estimated. The simulation result by this method closely matches experimental result. |
