This book which goes far beyond a traditional collection of technical articles is dedicated
to Enric Trillas a fuzzy systems pioneer but also an internationally renowned researcher in
other areas of science such as mathematics and aerospace and an outstanding manager of
scientific affairs in Spain. Some of the contributions in this book develop technical
state-of-the-art themes obviously related to fuzzy logic while others resemble popular-science
articles that shed light on complex mathematical concepts. There are also chapters that
highlight the authors' personal relationships and experiences working with Enric Trillas. While
planning this book project the editors decided to give contributors absolute freedom of
thought and expression in preparing their chapters. The result is a colorful and inspiring
mixture of styles and topics which perfectly reflects Enric Trillas's multifaceted
contributions to research and his outstanding role in promoting education and technological
transfer in the field of soft computing. This Festschrift to Enric Trillas published on the
occasion of his 75th birthday is not only intended as an exemplary source of information for
young scientists dealing with uncertainty imprecision and accuracy of models but also as an
inspiring guide to the role of scientists in education politics and communication.
