The natural mission of Computational Science is to tackle all sorts of human problems and to work out intelligent automata aimed at alleviating the b- den of working out suitable tools for solving complex problems. For this reason ComputationalScience,thoughoriginatingfromtheneedtosolvethemostch- lenging problems in science and engineering (computational science is the key player in the ?ght to gain fundamental advances in astronomy, biology, che- stry, environmental science, physics and several other scienti?c and engineering disciplines) is increasingly turning its attention to all ?elds of human activity. In all activities, in fact, intensive computation, information handling, kn- ledge synthesis, the use of ad-hoc devices, etc. increasingly need to be exploited and coordinated regardless of the location of both the users and the (various and heterogeneous) computing platforms. As a result the key to understanding the explosive growth of this discipline lies in two adjectives that more and more appropriately refer to Computational Science and its applications: interoperable and ubiquitous. Numerous examples of ubiquitous and interoperable tools and applicationsaregiveninthepresentfourLNCSvolumescontainingthecontri- tions delivered at the 2004 International Conference on Computational Science and its Applications (ICCSA 2004) held in Assisi, Italy, May 14-17, 2004.

Computational Science is becoming a vital part of many scienti?c investi- tions, impacting researchers and practitioners in areas ranging from aerospace andautomotiveto chemistry,electronics,geosciences,?nance,mathematics,and physics. Due to the sheer size of many challenges in computational science, the use of supercomputing, parallel processing, and sophisticated algorithms is - evitable. This volume contains the proceedings of The 2003 International Conference on Computational Science and Its Applications (ICCSA 2003), held in M- treal, Canada in May 2003. The papers presented here re?ect the aim of the programcommittee to bring together researchersand scientists from mathem- ics and computer science, the basic computing disciplines, and researchers from various application areas who are pioneering advanced application of compu- tional methods to sciences such as physics, chemistry, life sciences, engineering, arts, and the humanities, along with software developers and vendors, to d- cuss problems and solutions in the area, identify new issues, and shape future directions for research, as well as help industrial users apply various advanced computational techniques. Our outstanding invited speakers outlined the theme for the Conference, consideringsophisticatednumericalcomputationalmethods,emergingcompu- tional solutions, and problems and applications pushing the bounds of advanced computing techniques and hardware. This Conference was held as the ?rst in its series, with an emphasis on C- putational Science and the application of computational science. Interest from researchers and practitioners in this interdisciplinary area has been overwhe- ing, and we are looking forward to future events in this Conference series.

Although it is a relatively new approach to biometric knowledge representation, multimodal biometric systems have emerged as an innovative alternative that aids in developing a more reliable and efficient security system. This provides an in-depth description of existing and fresh fusion approaches for multimodal biometric systems.

The text here provides the reader with an in-depth overview and analysis of the fundamental methods and techniques developed following G. Voronoi's ground-breaking ideas, in the context of the vast and increasingly growing area of computational intelligence.
