We solve the Dirichlet problem for acoustic scattering from a surface which has been perturbed by the addition of one or more bumps. We build the solution for the bumpy case using the Green′s function for the unperturbed surface, and the solution of a local integral equation in which the integration is carried out only over the added bumps. We conclude

On certain nonlinear elliptic systems with indefinite terms
We consider an elliptic quasi linear systems with indefinite term on a bounded domain. Under suitable conditions, existence and positivity results for solutions are given. Submitted April 2, 2002. Published October 2, 2002.

Existence of two solutions for singular Φ-Laplacian problems
Existence of two solutions to a parametric singular quasi-linear elliptic problem is proved. The equation is driven by the Φ\Phi -Laplacian operator, and the reaction term can be nonmonotone.
