Drying kinetic of garlic cloves was investigated by considering different drying conditions. In this study, drying of garlic cloves was done by microwave–convective technique, using microwave powers of 100,180 and 300 W, air temperature of 40,100 and 140 0C. The samples sizes were about 1.09 gr. each, and with thickness of 5 and 7 mm and air velocity were held stable at 1m\s. A GMDH type–neural network was employed to estimate moisture content of garlic slices. Accuracy of the models was measured using the coefficient of correlation (R2) and root mean square error (RMSE). ). The results were found that GMDH had a good agriment with experimental data<\div>

In this study, A GMDH type–neural network was developed to predict LLE data for 2–butanol in the organic phase of ternary system (water + 2–butanol + 2–ethyl–1–hexanol) at various temperatures of 298.2, 308.2, 318.2, and 328.2K and atmospheric pressure. The predicted data were compared with the experimental data which have been previously reported. The average root mean square deviation (RMSD) between the observed and calculated mole fractions was used to reported errors, the estimated\predicted values of GMDH had a good agreement with experimental data<\div>

Drying techniques are used for maintaining and long survival of garlic cloves. In this study, drying of garlic cloves was done by microwave–convective technique, using microwave powers of 100,180 and 300 W, air temperature of 40,100 and 140 0C. The samples sizes were about 1.09 gr. each, and with thickness of 5 and 7 mm and air velocity were held stable at 1m\s. The effects of air temperature, microwave power and a samples thickness on the dehydration characteristics were determined. Two different mathematical models (Modified Page; Henderson and Pabis) and a developed model by the researchers were fitted to the experimental data. A developed model, was found to be more suitable for predicting drying of garlic cloves. In all stages of the mathematical modeling, multi– objective genetic algorithm was applied. Accuracy of the models was measured using the coefficient of correlation (R2) and root mean square error (RMSE). The results were found that the predictions of the developed model more accurately in comparison to other mathematical models<\div>
