Modeling precipitation from concentrated solutions with the EQ3/6 chemical speciation codes

Lee F. Brown, Michael H. Ebinger
1998 Computers and Chemistry  
The two databases are much less extensive than the ideal solution data, and we investigated the comparability of modeling ideal solutions and nonideal solutions.  ...  The largest thermodynamic databases available for use by EQ3/6 assume that solutions behave ideally. However, two databases exist that allow modeling nonideal solutions.  ...

James C. French, Allison L. Powell, Charles L. Viles, Travis Emmitt, Kevin J. Prey
1998 Proceedings of the 21st annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '98  
Our initial results confirm that the gGZOSS estimators are excellent predictors of the Ideal(Z) ranks but that the Ideal(l) ranks do not estimate relevance-based ranks well.  ...  We describe a testbed for database selection techniques and an experiment conducted using this testbed.  ...  But, for later reference we note that Max(O) = Sum(O) = Ideal(O), (2) that is, at threshold 1 = 0 both estimators give identically the Ideal(O) ranking of databases for all queries.  ...
