Time-Temperature Superposition analysis is often applied to frequency modulated data obtained by Dynamic
Mechanic Analysis (DMA) and Rheometry in the analytical chemistry and physics
areas. These techniques provide estimates of material mechanical properties
(such as moduli) at different temperatures in a wider range of time. This
package provides the Time-Temperature superposition Master Curve at a referred
temperature by the three methods: the two wider used methods, Arrhenius based
methods and WLF, and the newer methodology based on derivatives procedure.
The Master Curve is smoothed by B-splines basis. The package output is composed
of plots of experimental data, horizontal and vertical shifts, TTS data, and TTS
data fitted using B-splines with bootstrap confidence intervals.
