Yoshisuke Ueda
Biography
Yoshisuke Ueda has made fundamental and sustained contributions to the field of chaotic phenomena. He was the first to show experimental evidence that chaotic phenomena were possible in electronic circuits – calling his discovery a “broken-egg” attractor. In the decades that followed, research activity on the theory and application of chaos flourished and brought significant breakthroughs to areas of communication and cryptography. Recent studies of neural networks are based on nonlinear coupled circuits, where the existence of chaos is one of the most important features of their functional capabilities. The phase portrait diagram, bifurcation diagram, and spectral analysis of chaotic time series presented by Ueda are valuable guidelines for engineering applications of the mechanisms and properties of chaotic phenomena.
Ueda is a professor emeritus at Kyoto University, Kyoto, Japan.
