Calculation of argon trimer rovibrational spectrum

Rovibrational spectra of Ar3 are computed for total angular momenta up to J=6 using row-orthonormal hyperspherical coordinates and an expansion of the wave function on hyperspherical harmonics. The sensitivity of the spectr...

Adaptive Updating of Meta-Models in Hyperspherical Domains

The meta-modeling is frequently used method for analysis of the complex systems. Its basic part constitutes the design of experiments (DoE) - it is crucial to select the training points with consideration. Therefore the appropriate design pr...

Updating of Meta-Models in Hyperspherical Domains beyond the Original Bounds

Meta-modeling is an often used method for the analysis of complex system behavior. It enables a large number of evaluations in cases when the original model is costly or time-consuming. Usually the meta-model has to be updated to obtain bett...
