7 PREFACE The idea of preparing this volume originated from the ever increasing importance of computational modelling of complex problems in medicine. Considerable advances have been made in this area as demonstrated by the continued success of the International Conference on Modelling in Medicine and Biology organised by the Wessex Institute of Technology, the first of which was held in Southampton (1991), followed by Bath (1993), Milan (1995), Acquasparta (1997), Ljubljana (2003), Bologna (2005), The New Forest (2007), Crete (2009), and Riga (2011). The work reported at those meetings and the research carried out at our Institute indicated the increasing interaction and collaboration between medical and engineering scientists. The advances presented at some of our conferences are now being used in practice for a wide range of medical and surgical applications. The considerable improvements and evolution of the field led me to invite some of the best scientists who have participated in our conferences to write an article on their most recent research. This has led to thirteen outstanding articles published in this volume which encompass important areas of biomedical modelling. As the Editor of this book I am indebted to all authors for the quality of their contributions and I hope that the reader will find this volume useful. Carlos A. Brebbia Director Wessex Institute of Technology The New Forest, 2011
