EFFECTIVE SEARCH OF STARTING VALUES FOR KINETIC-PARAMETERS ESTIMATION

For the calculation of kinetic parameters from thermal data files nume ric optimization has been well introduced. But suitable starting value s near the global minimum of the sum of deviation squares are needed f or a successfully parameter estimation. Namely the search for starting values requires a lot of time and diminishes the effectiveness of the total procedure. Therefore we have developed an algorithm of the auto matic search of starting values for the optimization of activation ene rgy end frequency factor of a chemical reaction. This search procedure uses the knowledge of the specific course of the corresponding SDS su rface in the near of its global minimum. In this area the SDS describe s two plateaus separated by a narrow valley. The search procedure avoi ds starting values at one of these plateaus. This PC program is part o f the complex software package TA-kin v3.3 for kinetic evaluation of t hermal measurements.
