Researchers from around the world summarize key guidelines on modeling, simula- tion, control synchronization, and applications of these systems. The organization of the book includes twelve chapters covering a wide variety of engineering areas regard- ing basic scientifi c research and technological development. The fi rst chapter presents a time series technique to forecast future events. The sec- ond chapter analyzes forecasting chaos, providing a deep insight on the meaning of Lyapunov exponents locally. The predictability of chaotic events considering initial error in chaotic systems is presented in chapter three. The fourth chapter introduces a microscopic theory of transport phenomena which is supported by applying Hamilto- nian forms. These four chapters motivate the reader to look for approaches to control and synchronization of chaotic systems. Furthermore, chapters fi ve, six and seven focus on controlling the chaos phenomenon. For instance, micro-electromechanical systems like resonators might present chaotic behavior, the prediction and control of chaos is then presented in chapter fi ve. Chaotic systems can be perturbed, and control and identifi cation approaches can be applied as shown in chapter six. Among all techniques for controlling chaos the adaptive one is very useful, as described in chapter seven. Chaos systems can be synchronized as shown in chapters eight and nine. In chapter nine a technique for chaos control called feedback control, is also presented. Some realizations of chaotic oscillators with electronic circuits are presented in chapter ten. In this chapter two chaos systems are synchronized by Hamiltonian forms and observer approach, to realize a secure communication system. Chapter eleven introduces estimation techniques for chaos systems to develop digital communications. Some open research problems can be identifi ed in these eleven chapters, as well as in the fi nal chapter devoted to the emergence of matured chaos during network growth. This book includes recent advances in science and engineering applications. However, as highlighted in the majority of chapters, still many research and applications are very much in need of further development. In this way, the book is a good source for identifying basics on chaotic systems, techniques to control and synchronize them, and to acquire recent knowledge and ideas for future research in this area. Some applications to engineering motivate the reader to develop experiments applied to real X Preface life problems. This book is intended for students, academia and industry since the col- lected chapters provide a rich cocktail while balancing theory and applications. Enjoy the book!
