Capillarity phenomena are all about us; anyone who has seen a drop of dew on a plant leaf or the spray from a waterfall has observed them. Apart from their frequently remarked poetic qualities, phenomena of this sort are so familiar as to escape special notice. In this sense the rise of liquid in a narrow tube is a more dramatic event that demands and at first defied explanation; recorded observations of this and similar occur­ rences can be traced back to times of antiquity, and for lack of expla­ nation came to be described by words deriving from the Latin word "capillus", meaning hair. It was not until the eighteenth century that an awareness developed that these and many other phenomena are all manifestations of some­ thing that happens whenever two different materials are situated adjacent to each other and do not mix. If one (at least) of the materials is a fluid, which forms with another fluid (or gas) a free surface interface, then the interface will be referred to as a capillary surface.

Much of the material in this book comes from what I've learned as I've traveled around the country conducting seminars about working profitably in the automated office. During the first few months of those seminars, there was a question I was asked more often than any other single question. I wa~ asked the question so often that I gave it a nickname. I called it my "What The Devil" question. Often in different words, usually at the morning break in the seminar, and almost always with an effort not to offend or embarrass, I was asked, "What the devil is a psychologist doing conducting seminars about computer systems?" I'm not asked "What the Devil" questions much anymore. Those familiar with office automation have come to realize that human factors chiefly determine whether a computer system will be a success or an expensive failure. So many computer systems have not gained acceptance by is employees because the planners didn't use good psychological sense. That especially true as the computers move from the Engineering Department into the executive suites and the role of computers changes from just producing paper into also assisting in managerial decision making. One human factor I've learned is that people would much rather skip around in a book than read it from front cover to back cover directly. It's true whether the book is a user manual for office equipment or a volume on computer systems for decision makers.

Many mechanics and physics problems have variational formulations making them appropriate for numerical treatment by finite element techniques and efficient iterative methods. This book describes the mathematical background and reviews the techniques for solving problems, including those that require large computations such as transonic flows for compressible fluids and the Navier-Stokes equations for incompressible viscous fluids. Finite element approximations and non-linear relaxation, augmented Lagrangians, and nonlinear least square methods are all covered in detail, as are many applications.

This book constitutes the refereed proceedings of the 7th Annual SmartCity360° Summit which was organized in November 2021 in Porto, Portugal. Due to COVID-19 pandemic the conference was held virtually. The volume combines selected papers of 6 conferences, namely EdgeIoT 2021 - International Conference on Intelligent Edge Processing in the IoT Era; IC4S 2021 - International Conference on Cognitive Computing and Cyber Physical Systems; SmartGov 2021 - International Conference on Smart Governance for Sustainable Smart Cities; SmartGift 2021 - International Conference on Smart Grid and Innovative Frontiers in Telecommunications; e PFSM 2021 - International Conference on Privacy and Forensics in Smart Mobility.
