in this work, artificial neural network (ann) has been employed to propose a practical model forpredicting the surface tension of multi-component mixtures. in order to develop a reliable modelbased on the ann, a comprehensive experimental data set including 15 ternary liquid mixtures atdifferent temperatures was employed. these systems consist of 777 data points generally containinghydrocarbon ...

By using the quantum Ising chain as a test bed and treating spin polarization along external transverse field "generalized density", we examine performance of different levels density functional approximations parallel to those widely used for interacting electrons, such local approximation (LDA) generalized gradient (GGA). We show that by adding lowest-order nearest-neighbor variation correcti...
