The Twelfth IASTED International Conference on Intelligent Systems and Control (ISC 2009) will be an international forum for researchers and practitioners interested in the advances in and applications of intelligent systems and control. It is an opportunity to present and observe the latest research, results, and ideas in these areas. ISC 2009 aims to strengthen relationships between industry, research laboratories and universities. The conference will focus on Intelligent Data Systems and Intelligent Control Systems and their applications. Rapid developments in these areas have resulted in more intelligent, sensitive, and accurate methods of data acquisition and data processing, as well as adaptive and robust control in manufacturing, in environmental and medical monitoring systems, as well as in process inspection, quality control, diagnostics, and other processes. 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. ISC 2009 will be held in conjunction with the IASTED International Conferences on: · Telehealth and Assistive Technology (TAT 2009) · Robotics and Applications (RA 2009) · Parallel and Distributed Computing and Systems (PDCS 2009) · Software Engineering and Applications (SEA 2009)
