The results of heat capacity calculation (overall average absolute percentage deviation) for a total of 176 data points for MEA+2-PE+water system are 0.2 and 7.4% for molar heat capacity and excess molar heat capacity, respectively.
Enhanced prediction accuracy of the RKS model is also established by comparing the mean absolute error in the predicted values obtained using the proposed RKS model with those of the ANN model (Nehdi et al. 2001), in which the average absolute value of the predicted filling capacity, slump value, segregation resistance and compressive strength were 0.05, 0.04, 0.07 and 0.07 respectively.
An extended Redlich Kister-type equation was used to coRedlich Kister-typety with concequationn and temperature; the average absolute deviation (AAD) of the 198 data points from the corresponding values predicted by the correlation was 0.1%.
The equation fit the results with the average absolute deviation (AAD) of 2.1% and 0.2% for the excess molar heat capacity and molar heat capacity, respectively.
A total of 165 data points fit into the model resulted in a low overall average absolute deviation of 4.6% and 0.3% for the excess molar heat capacity and molar heat capacity, respectively.
The moderate-intensity exercise bout consisted of continuous cycling performed on a cycle ergometer at 50% of individual maximal workload capacity of the patients, translating to an average absolute workload of 85 ± 4 W (∼6 MET).
For a total of 176 data points for the (DEA + MDEA + water) system, the overall average absolute percentage deviation of the calculations are 16.5%and0.2%2% for the excess molar heat capacity and the molar heat capacity, respectively.
The average absolute relative deviation of RBF-NN and MLP-NN models for predicted heat capacity data was 0.83% and 1.04% respectively.
The average absolute deviations of 2.8%, 4.1% and 3% from experimental data for pressure drop, capacity and outlet temperature respectively, indicate the model validity.
The accuracy of the proposed equations was tested and found to be in excellent agreement with the reported data for the wide range of conditions, wherein the average absolute deviation percent of proposed equations are 0.77% and 2.35% for downcomer design velocity and vapor capacity factor respectively.
