We consider the inverse problem to determine the shape of a local perturbation of a perfectly conducting plate from a knowledge of the far-field pattern of the scattering of TM polarized time-harmonic electromagnetic waves by reformulating it as an inverse scattering problem for a planar domain with corners. For its approximate solution we propose a regularized Newton iteration scheme. For a foundation of Newton type methods we establish the Fréchet differentiability of the solution to the scattering problem with respect to the boundary and investigate the injectivity of the linearized mapping. Some numerical examples of the feasibility of the method are presented. For the sake of completeness, the first part of the paper outlines the solution of the direct scattering problem via an integral equation of the first kind including the numerical solution.

This manual contains the charts, graphs, and calculations necessary to establish design criteria for buoyant screw propulsion. Two phases of tests were conducted. The first was the testing of a systematically varied series of buoyant screw models and the second was the testing of certain miscellaneous configurations.

This paper introduces a new high Level programming language for a novel class of computational devices namely data-procedural machines. These machines are by up to several orders of magnitude more efficient than the von Neumann paradigm of computers and are as flexible and as universal as computers. Their efficiency and flexibility is achieved by using field-programmable logic as the essential technology platform. The paper briefly summarizes and illustrates the essential new features of this language by means of two example programs.
