Optimization of Critical Temperature Molecular Effect Model Predictions Series with 2D Graphical Statistics for High Temperature Superconductors Thallium Class [TC < 0°, TC > 0°]

In High Temperature Superconductors (HTCSs) Molecular Effect Model (MEM) publication series, Critical Temperature Inverse Least Squares Predictions (ILS) with 2D Numerical/Graphical Optimization in Thallium group of [Tl-Sn-Pb-Ba-Si-Mn-Mg-Cu-O] are shown. These approximations are constrained for selected compounds with [TC < 0°, TC > 0°]. Tetragonal Lattice and Amorphous compounds of this Thallium class are not included yet. Results, additionally, comprise a 2D Statistics Graphics series subject to these conditions with 97% Confidence Intervals. Solutions and low errors with 2D Numerical Optimization techniques to validate the MEM for this class are presented. 2D Graphical-Statistical results comprise 97% confidence interval approximations. Electronics Physics applications for Superconductors in general, and HTSCs are described.
