Effects of the Steam-To-Oxygen Ratio and the Equivalence Ratio on Underground Coal Gasification
Combustion Science and Technology, 2023 Underground coal gasification is a complex physico-chemical process. UCG thermodynamic equilibrium model was established and validated, and the effects of the steam-to-oxygen ratio (RH2O/O2) and the equivalence ratio (ER) on the gasification temperature and the gaseous products were investigated.

On the Equivalence between the Primal-Dual Schema and the Local-Ratio Technique [PDF]
SIAM Journal on Discrete Mathematics, 2001 We discuss two approximation paradigms that were used to construct many approximation algorithms during the last two decades, the primal-dual schema and the local ratio technique. Recently, primal-dual algorithms were devised by first constructing a local ratio algorithm and then transforming it into a primal-dual algorithm.
