Barsky, USA Leonid Kazovsky, USA Rao Kamissety, USA Stamatios Kartalopoulos, USA Preface This year the 12th WSEAS International Conference on MATHEMATICAL and computational METHODS in SCIENCE and ENGINEERING (MACMESE '10) was held at the University of Algarve, Faro, Portugal, November 3-5, 2010.

6 The conference remains faithful to its original idea of providing a platform to discuss new MATHEMATICAL methods and computational techniques or applications of known MATHEMATICAL methods and computational techniques ( differential equations, FEM, BEM, variational calculus, stochastic systems, cellular automata, wavelets, integral equations, universal approximants, optimization and search, clustering and density estimation, filtering and state estimation, linear and non-linear time series, simulation techniques, neural networks, fuzzy logic, evolutionary computing, orthogonal transforms, wavelets, forecasting etc).

7 With participants from all over the world, both from academia and from industry. Its success is reflected in the papers received, with participants coming from several countries, allowing a real multinational multicultural exchange of experiences and ideas. The accepted papers of this conference are published in this Book that will be indexed by ISI. Please, check it: as well as in the CD-ROM Proceedings. They will be also available in the E-Library of the WSEAS . The best papers will be also promoted in many Journals for further evaluation.

8 A Conference such as this can only succeed as a team effort, so the Editors want to thank the International Scientific Committee and the Reviewers for their excellent work in reviewing the papers as well as their invaluable input and advice.
