I first met Dr. Nishio at the IEEE ISCAS'89 Conference in Portland OR and since then, on and off at conferences where I got interested in methods and results concerning the behavior of nonlinear coupled oscillator circuits. Later, Dr. Nishio visited me several times, in particular, during 1 year from 2000 to 2001. What was interesting for me in Dr. Nishio’s work was his meticulous study of the various dynamical regimes in coupled oscillator circuits. What he took home from my lab was the search for rigorous results on the one hand and for applications on the other hand.

1. ANALYSIS OF NONLINEAR COUPLED OSCILLATORY CIRCUITS

The nominee has been working on coupled systems of periodic and chaotic oscillatory circuits. Various unknown chaotic and/or synchronization-related phenomena have been unveiled. His knowledge of classical synchronization phenomena of coupled oscillator circuits/networks and his experience of developing various kinds of simple chaotic circuits were combined to produce many new results.

In his early works on this topic, the nominee reported "quasi-synchronization of chaos", "double-mode chaos", and "asynchronous simultaneous chaotic oscillation" observed from simple coupled chaotic circuits. Those phenomena had not been known before his publications. Further, the nominee reported "spatio-temporal chaos" observed from a small number of coupled chaotic circuits. At that time, spatio-temporal chaos had been already known as a typical phenomenon observed from a large size of chaotic networks mainly in coupled systems of discrete-time mathematical models. The nominee showed in his simple circuit that the essential mechanism of spatio- temporal chaos was coexistence of steady states characterized by the position of the chaotic cells in the network and their instability caused by local chaotic behavior. His next step was a development of analyzing methods of the spatio-temporal chaos, more precisely chaotic wandering over several phase states, observed from coupled chaotic circuits, because direct approaches were almost impossible for the complicated phenomena he discovered. His statistical method using newly introduced dependent variables corresponding to the phases of the solutions enabled him to analyze the phenomena statistically. Next, he proposed a modeling method of the chaotic wandering by Markov chains and showed its effectiveness. He also applied a similar modeling method with Markov chains to a complicated phenomenon related with intermittency chaos. These modeling methods using Markov chains can be applied for any kind of complicated phenomena based on chaotic wandering, if all possible states of the system can be represented by discrete states and their transition probabilities can be estimated by computer simulations or real experiments. Hence, this approach can be useful to analyze and control general complex networks.

The "frustration" structure of coupled oscillator networks is another subject of the nominee's research. He has been interested in what kinds of synchronization occur on the border between stable and unstable states. He reported a recent publication that coupled polygonal oscillatory networks with frustration exhibit interesting synchronization phenomena and proposed a new algorithm for computing the phase differences between the oscillators by calculating the minimum value of a power consumption function under some simple assumptions. The proposed algorithm is much simpler than the standard averaging method and is useful for the analysis of larger size networks. Through the research on coupled oscillatory circuits, the nominee has developed several effective analysis methods for various types of nonlinear circuits; a method for analyzing chaotic circuits including lossy/lossless transmission lines, a stability check for the characteristic curves of nonlinear resistive circuits, and a SPICE-oriented algorithm combining a frequency-domain relaxation method and the multi-dimensional Fourier transformation for nonlinear circuits driven by multi-tone signals. All methods were illustrated by applying them successfully to nontrivial examples.

2. ANALYSIS AND APPLICATION OF SIMPLE CHAOTIC SYSTEMS

The approach of the nominee in the beginning of his research career was to derive low-dimensional Poincare maps from simple chaotic circuits by idealizing the nonlinear elements and to analyze chaotic phenomena for these maps. His mathematical ability to derive or to analyze one-dimensional maps enabled him to produce several new results. His deep insight into the behavior of the iterations of one- dimensional chaotic maps allowed him to design new schemes of chaos applications in the field of information processing. His pioneering work on chaos cryptosystems using one-dimensional chaotic maps was a prototype followed by several researchers. He also discovered the continuous characteristics of the sequences generated by one-dimensional chaotic maps and exploited this feature for error detection and correction in digital communication schemes.

On top of his research, the nominee also made continuous efforts over the years to promote research in nonlinear dynamics and its applications in Japan through the NOLTA Conference and most recently through a new journal, the NOLTA journal. Of course, in this endeavor he was not alone, but he was first a “work-horse” and later an organizer with strategic views. The result of his continuous efforts and those of his colleagues is that today in Japan there is a large and internationally renowned community of researcher in this field that produces many exciting results. He also volunteers in the CASS-Society and is an important link between IEEE-CAS and IEICE-NOLTA.

Chaotic wandering in four coupled chaotic circuits is observed. Dependent variables corresponding to phases of solutions in sub-circuits were introduced in order to analyze the chaotic wandering. Combining the variables with hysteresis decision of the phase states enabled statistical analysis on the chaotic wandering. This was the first research outcome which analyzed chaotic wandering in simple coupled chaotic circuits.

Markov chain modeling of complicated phenomena observed from coupled chaotic circuits is introduced. Once the transition probability matrix was obtained from computer simulation results, various statistical quantities of chaotic wandering of synchronization states and switching of clustering states are calculated from the model. The nominee conducted most part of this research by himself. This modeling method can be used to analyze chaotic networks without integrating differential equations and hence contributes to examine rare events in complex networks.

Synchronization phenomena observed in several types of coupled polygonal oscillatory networks including frustrations in their coupling structures are investigated. Minimizing the power consumption at coupling resistors of the whole system proved to be more effective to determine synchronization states than the classical averaging method. The nominee contributed to develop this method and supervised the first author who is his former Ph.D student and current assistant professor. This analysis can be applied to more general networks and can make an impact on wider research area like network science.
