โœฆ Synopsis

This paper looks at the numerical characteristics of penalty methods for evaluating the solution of symmetric systems of equations with imposed constraints. The sources of error resulting from this approach are identified and an estimate for the penalty parameter that minimizes this error is obtained. The results of the error analysis and the effect of penalty parameter on the accuracy and rates of convergence of the solution algorithm are demonstrated with the aid of some numerical examples.

## Abstract Our goal in the present article to give an insight on some important questions to be asked when choosing a Kriging model for the analysis of numerical experiments. We are especially concerned about the cases where the size of the design of experiments is relatively small to the algebrai

## Abstract In linearized optimization theory, lifting surfaces shed tip vorticity of which the strength has in general infinite square root singularities. Here we impose, besides the usual condition on the force action of the lifting surfaces, also a condition on the strength of their shed vortici
