Table 1 Physical and coded values for input factors Input factors Coded values of input factors x i,min x i,0 x i,max (−1) (0) (+1) Compaction pressure, x1 (Mpa) 50 100 150 Drying temperature, x2 °CC) 25 62.5 100 Molasses mass, x3 0 5 10.
Consequently, specimen information systems should be designed to collect critical annotations as coded values.
The optimum coded values of three test variables were computed as x1 = 0.125, x2 = 0.707, and x3 = 0.107 by using a LOQO/AMPL optimization algorithm.
Under the optimal conditions theoretical (predicted) band gap of CdS (2.66 eV) was calculated using optimal coded values from the model and the theoretical value is good agreement with the value (2.72 eV) obtained by verification experiment.
temperature (10 50 °C), initial pH of solution (2 10), initial dye concentration (140 220 mg/l), and adsorbent dose (1 5 g/l) were transformed to coded values and quadratic model was built to predict the responses.
temperature (10 50 °C), pH of solution (2 10), dye concentration (240 400 mg/l), and adsorbent dose (1 5 g/l) were transformed to coded values and a second-order quadratic model was built to predict the responses.
Corresponding values for these coded values were given for each tested factor.
The coded values for the variables are shown in Table 1.
The model coefficients and probability values, i.e., coded values, are shown in Table 4.
