This is a practical book, to be sure, but it is also a book about hope and posi- tive change. I am quite sincere. The delivery of electricity is deeply rooted in the principle of universal access; when clean, reliable energy is available it contributes to poverty alleviation, improved social conditions, and enhanced economic development. In the developed world, we know this to be true. The digital fabric of Our lives is a testimony to the importance of energy security. Across the globe, we have seen the vital contributions that electrification has brought to the development of economies and an enhanced quality of life. Nonetheless, this supreme engineering achievement has languished, and we are deeply challenged.

Commercial energy storage has moved from the margins to the mainstream as it fosters flexibility in Our smarter, increasingly integrated energy systems. The energy density, availability, and relatively clean fossil profile of natural gas ensure its critical role as a fuel for heating and electricity generation. As a transportation fuel, natural gas continues to increase its market penetration; much of this has been enabled by emerging developments in storage technology.

December 2007, San Jose, California: It seems a long time ago. I walked into a big networking company to head their small Power over Ethernet (PoE) applications team. Surprisingly, I hardly knew anything about PoE prior to that day, having been a switching-power conversion engineer almost all my life. But it seemed a great opportunity to widen my horizons. As you can see, one notable outcome of that seemingly illogical career choice five years ago is the book you hold in yOur hands today. I hope this small body of work goes on to prove worthy of yOur expectations and also of all the effort that went into it. Because, behind the scenes, there is a rather interesting story to relate—about its backdrop, intertwined with a small slice of modern PoE history, punctuated by a rather res- tive search for Our roots and Our true heroes, one that takes us back almost two centuries

The electrical power grid is often referred to as one of the most complex man- made systems on Earth. Its importance to all aspects of Our daily lives, economic stability, and national security cannot be overstated, and the need for an updated, secure, resilient, and smarter power grid infrastructure is increasingly recognized and supported by policy makers and market forces.

The next avatar of the Internet will revolutionize Our world. In time, it will provide us a universal remote control, enabling us to monitor and control physical objects located anywhere on the planet, using a smart phone. It will make the universe around us programmable, allowing us to script the behav- ior of physical objects with electronic commands. This book is about such an emerging new version of the Internet.

Radio frequency identification (RFID) is gaining in popularity, especially as we find Ourselves in this communications age and headed towards a ubiquitous computing world. Automatic identification systems become an important aspect not just in today’s technology but also as part of Our daily life. We need RFID in Our cars, transportation systems, access points, and even simple transactions; we also acknowledge the need for RFID in Our logistics systems, healthcare, and tracking and locating applications.

To a quantum mechanic the whole universe is one godawful big interacting wavefunction ? but to the rest of us, it’s a world full of separate and distinguishable objects that hurt us when we kick them. At a few months of age, human children recognize objects, expect them to be permanent and move continuously, and display surprise when they aren’t or don’t. We associate visual, tactile, and in some cases audible and olfactory sensations with identifiable physical things. We’re hardwired to understand Our environment as being composed of separable things with specific properties and locations. We understand the world in terms of what was where when.

Fun. We (yOur authors) wanted a word to describe Our ultimate goal for this book, as well as a word we hope you (Our reader) will use to describe it, and that’s the one we chose. There are others goals, of cOurse, but in the end, when you’ve finished the book, we’re hoping you’ll have enjoyed the activities described in these pages. Many books use the Introduction to explain exactly what the book is about, what the reader will learn, what the reader needs (a skill or maybe an item or piece of software), and what the reader will be left with when that last page is completed. And this Introduction will do those things, but … hopefully it’ll make you excited to get started.

There’s a story (it’s either an old vaudeville joke or a Zen koan) in which a fisherman asks a fish, “What’s the water like down there?” and the fish replies “What is water?” If the story is just a joke, the point is to make us laugh; but if it’s a koan, the point is that the most obvious and ubiquitous parts of Our immediate environ- ment are, paradoxically, often the easiest to overlook.

The basic topic of this book is solving problems from system and control theory using convex optimization. We show that a wide variety of problems arising in system and control theory can be reduced to a handful of standard convex and quasiconvex optimization problems that involve matrix inequalities. For a few special cases there are “analytic solutions” to these problems, but Our main point is that they can be solved numerically in all cases. These standard problems can be solved in polynomial- time (by, e.g., the ellipsoid algorithm of Shor, Nemirovskii, and Yudin), and so are tractable, at least in a theoretical sense. Recently developed interior-point methods for these standard problems have been found to be extremely efficient in practice. Therefore, we consider the original problems from system and control theory as solved.
