Technology and the Human: Hans Jonasxpression for the curve will have a denominator of δ(.). It is thus of computational interest to define corresponding sets of coefficient functions and basis functions that are scaled by a factor of δ(.). This would simplify the expressions and eliminate redundant divisions. These scaled coefficient

Technik der Impfstoffe und Heilsera involves the computation of points on the surface for many different values of the domain parameters. The determination of a point on the patch requires the evaluation of the surface formulation at an appropriate (.) value. This entails the evaluation of the four basis functions at the value of . a

The continuous analogues of β1 and β2 will be denoted β1.(.) and β2.(.), respectively, and describe the value of each shape parameter at the point ..

This concept was first analytically modeled by Schweikert in [23] and an alternative development was given in [6] and generalized in [19]. A detailed derivation of the generalized form based on a variational principle is given in [1].
