Prediction of Hydrogen-Bonding Interaction Free Energies with Two New Molecular Descriptors

open access: yesLiquids
This work is a continuation of our recent work on the prediction of hydrogen-bonding (HB) interaction enthalpies. In the present work, a simple method is proposed for the prediction of the HB interaction free energies.

Balance control of grid currents for UPQC under unbalanced loads based on matching-ratio compensation algorithm [PDF]

open access: yes, 2018
In three-phase four-wire systems, unbalanced loads can cause grid currents to be unbalanced, and this may cause the neutral point potential on the grid side to shift.
