The following modifications are made to the Original UNIFAC model:
<math> ln \gamma^C_i = 1 - V'_i + ln V'_i - 5 q_i (1 - \frac{V_i}{F_i} + ln \frac{V_i}{F_i}) </math>
<math> V_i' = \frac{r_i^{3/4}}{\sum_j r_j^{3/4} x_j} </math>
<math> \Psi_{nm} = exp(- { {a_{nm} + b_{nm} T + c_{nm} T^2} \over {T} }) </math>
