题目：Synchronization and Frustration in Coupled Oscillatory Circuits
报告人：Prof. Yoshifumi Nishio，Tokushima University
Synchronization of oscillation is one of basic phenomena observed in natural fields and its analysis is important in order to understand natural phenomena and to apply them to future engineering applications. Coupled oscillatory circuits are good models to analyze synchronization, because they can simulate mechanical systems, chemical systems, and biological systems with stronger robustness, better reproducibility, quicker responses, and easier experiments. In this talk, synchronization phenomena observed from coupled van der Pol oscillators, which is the most basic oscillator, are described, in particular under the condition such that the oscillators are coupled with some kinds of frustrations. First, basic synchronizations of two coupled van der Pol oscillators are introduced. Secondly, several kinds of coupled systems of oscillators with frustrations are investigated. Some recent results are also introduced.
Prof. Yoshifumi Nishio received his B.E., M.E., and Ph.D. degrees in electrical engineering from Keio University, Yokohama Japan, in 1988, 1990, and 1993, respectively. In 1993, he joined the Department of Electrical and Electronic Engineering at Tokushima University, Tokushima Japan, where he is currently a Professor. From May 2000 he spent a year in the Laboratory of Nonlinear Systems (LANOS) at the Swiss Federal Institute of Technology Lausanne (EPFL) as a Visiting Professor. His research interests are in the areas of nonlinear circuits engineering, including analysis and application of chaos in electrical circuits, analysis of synchronization in coupled oscillatory circuits, development of analyzing methods for nonlinear circuits, theory and application of cellular neural networks, neural network architecture, complex networks, evolutionary computation, and bio-signal processing. He is author or co-author of more than 600 journal/conference papers. Recently, he edited a book: "Oscillator Circuits; Frontiers in Design, Analysis and Applications", which has been published from IET. He supervised 14 PhD students on subjects related to his research interests. He was the Chair of the IEEE CAS Society Technical Committee on Nonlinear Circuits and Systems (NCAS) during 2004-2005, the Steering Committee Secretary of the IEICE Research Society of Nonlinear Theory and its Applications (NOLTA) during 2004-2007, the Chair of the IEEE CAS Society Shikoku Chapter during 2011-2014, and a member of the IEEE CAS Society Board of Governors during 2012-2017, and is currently the Vice President on Regional Activities and Membership of the IEEE CAS Society (from 2018). He was an Editor of the IEICE Fundamentals Review during 2007-2012 and an Associate Editor of the IEEE Transactions on Circuits and Systems-I: Regular Papers during 2004-2005, the IEEE Transactions on Circuits and Systems-II: Express Briefs during 2012-2013, the IEEE CAS Magazine during 2008-2009, and the RISP Journal of Signal Processing during 2005-2012. He is currently serving as a Secretary for the NOLTA, IEICE (from 2009) and an Associate Editor for the IEEE CAS Society Newsletter (from 2007), the IEEE Transactions on Circuits and Systems-II: Express Briefs (from 2016) and International Journal of Bifurcation and Chaos (from 2015). He is also a member of the Editorial Board of International Journal of Circuit Theory and Applications. He is a senior member of the IEEE, and a member of the IEICE and the RISP.
