Frequency and Voltage Scaling Design,proving stability and error estimates have to take care of the fact that the solutions of the equations considered contain singularities. In Section 2 we derive stability conditions for a quadrature method using splines for a weakly singular integral equation. The same equation is considered in the

If those problems are converted via the direct method into boundary integral equations, the solutions of the latter inherit those edge and corner singularities. The singularities disturb the convergence of numerical schemes, e g finite element or boundary element methods. Numerical schemes conve

After Hess & Smith [17] introduced the panel methods into fluid mechanics, many different methods have been developed [31, 32, 41]; surveys of the existing methods are given by Wagner [45, 46] Hoeijmakers [18] and Hess [16]. With the increasing use of computers, lifting surface theories [43,

Our ideas are based on the procedures by E.L. Allgower [1] and on local geometry properties [2], The algorithm allows a parallel discretization and was tested for several examples
