The ebook has been put together by the IEEE Systems, Man & Cybernetics Society in the UK & the Republic of Ireland. It comprises articles presented at the 11th IEEE International Conference on Cybernetic Intelligent Systems (CIS 2012), held from 23-24 August 2012 at the University of Limerick, Ireland. We are grateful to Dr. Mouraud Oussalah and Prof. Ali Hessami for their work in putting together this issue. They give their own introduction to the papers, in the form of a tribute to the late Prof John St. Quinton, whose article we publish here posthumously.
