COMPARISON OF 2-VARIABLE INTERPOLATION METHODS FOR PREDICTING THE VAPOUR PRESSURE OF AQUEOUS GLYCEROL SOLUTIONS
Several general mathematical methods for approximating two variable functions are applied for the study of
the temperature - concentration - vapour pressure relation of aqueous glycerol solutions. The general properties of the
applied methods are also discussed for possible other applications

Proceedings of the NASA Workshop on Surface Fitting
Surface fitting techniques and their utilization are addressed. Surface representation, approximation, and interpolation are discussed. Along with statistical estimation problems associated with surface fitting
Finding better weight functions for generalized Shepard's operator on infinite intervals
In this paper, we investigate the difference of Shepard's generalized operators S(sigma) from the approximated set of data for various weight functions sigma. Bounds are given for the sizes of the 'bumps' shown on the graph of S(sigma) for sigma(d) = 1/d in dimension N = 1, and the best weight function sigma for practical use is proposed
