The 18th IASTED International Conference on Applied Simulation and Modelling (ASM 2009) will provide an international forum for researchers and practitioners to exchange new ideas and practical experience in the areas of simulation and modelling. It is an opportunity to present and observe the latest research, results, and ideas in these areas. ASM 2009 aims to strengthen relations between industry practitioners, research laboratories, and universities. All papers submitted to this conference will be double-blind peer reviewed by at least two members of the International Program Committee and related technical committees. Acceptance will be based primarily on originality, significance, technical soundness, presentation, and references. The conference chair makes the final decision on the acceptance or rejection of the paper. ASM 2009 will be held in conjunction with the IASTED International Conferences on: · Power and Energy Systems (EuroPES 2009) · Artificial Intelligence and Soft Computing (ASC 2009)
