The traditional systems disciplines of communications, computation, control and signal processing are becoming increasingly important in addressing major technological challenges of the coming century, in fields such as materials processing, manufacturing automation, speech recognition and ubiquitous personal communications, among many others. Moreover the boundaries between these separate disciplines are being rapidly blurred by the many demands of these applications. This Tribute, dedicated to Thomas Kailath for his many seminal contributions to these areas, highlights several recent trends and results, described by leading scientists and engineers from around the world. The thirty-six papers in this volume present important results on, among others, interference cancellation in multipath channels, decision feedback equalization for packet transmission, blind equalization and smart antennas for mobile communications, displacement structure, fast and stable algorithms in numerical linear algebra, nonconvex optimization problems, issues in nanoelectronic computation, fundamental limits of control system performance, LQG control with communication constraints, nonlinear "H"INFINITY control, adaptive nonlinear control, model identification, tomographic deconvolution, and higher-order statistics. The applications discussed herein include packet radio, robotics, very flexible mechanical systems, power systems and power electronics, moving object detection, complexity management and several others. The volume starts out with a survey by Professor Kailath entitled Norbert Wiener and the Development of Mathematical Engineering', a term suggested by Wiener that can serve as a compact description of the variety of fields described herein.
This book is the result of a long friendship, of a broad international co- operation, and of a bold dream. It is the summary of work carried out by the authors, and several other wonderful people, during more than 15 years, across 3 continents, in the course of countless meetings, workshops and discus- sions. It shows that neither language nor distance can be an obstacle to close scientific cooperation, when there is unity of goals and true collaboration. When we started, we had very different approaches to handling the mys- terious, almost magical world of asynchronous circuits. Some were more theo- retical, some were closer to physical reality, some were driven mostly by design needs. In the end, we all shared the same belief that true Electronic Design Automation research must be solidly grounded in formal models, practically minded to avoid excessive complexity, and tested "in the field" in the form of experimental tools. The results are this book, and the CAD tool petrify. The latter can be downloaded and tried by anybody bold (or desperate) enough to tread into the clockless (but not lawless) domain of small-scale asynchronicity. The URL is http://www.lsi. upc. esr j ordic/petrify. We believe that asynchronous circuits are a wonderful object, that aban- dons some of the almost militaristic law and order that governs synchronous circuits, to improve in terms of simplicity, energy efficiency and performance.
Recognising the benefits of improved control, the second edition of Autotuning of PID Controllers provides simple yet effective methods for improving PID controller performance. The practical issues of controller tuning are examined using numerous worked examples and case studies in association with specially written autotuning MATLAB(r) programs to bridge the gap between conventional tuning practice and novel autotuning methods.
The extensively revised second edition expands and refines on important work in the ubiquitous PID form of control with material covering:
Autotuning of PID Controllers is more than just a monograph, it is an independent learning tool applicable to the work of academic control engineers and of their counterparts in industry looking for more effective process control and automation.
Comments on the first edition:
This book is written in a way which not only makes it easy to understand but is also useful to those interested in or working with PID controllers.
The book will be useful to manufacturers and users of control equipment, and also to researchers in the field of automatic tuning.
Today's Integrated Circuit (IC) architects depend on Electronic Design Automation (EDA) software to conquer the overwhelming complexity of Very Large Scale Integrated (VLSI) designs. As the complexity of IC chips is still fast increasing, it is critical to maintain the momentum towards growing productivity of EDA tools. On the other hand, single-core Central Processing Unit (CPU) performance is unlikely to see significant improvement in the near future. It is thus essential to develop highly efficient parallel algorithms and implementations for EDA applications so that their overall productivity can continue to increase in a scalable fashion. Among various emergent parallel platforms, Graphics Processing Units (GPUs) now offer the highest single-chip computing throughput. A large body of research has therefore been dedicated to accelerating EDA applications with GPUs. Electronic Design Automation with Graphic Processors is a timely state-of-the-art review of the existing literature on GPU-based EDA computing. Considering the substantial diversity of VLSI Computer Aided Design (CAD) algorithms, it puts forward a taxonomy of EDA computing patterns, which can be used as basic building blocks to construct complex EDA applications. GPU-based acceleration techniques for these patterns are then reviewed, and, building on this foundation, it goes on to survey recent works on building efficient data-parallel algorithms and implementations to unleash the power of GPUs for EDA applications.
The eld of wireless sensor networks continues to evolve and grow in both practical and research domains. More and more wireless sensor networks are being used to gather information in real life applications. It is common to see how this technology is being applied in irrigation systems, intelligent buildings, bridges, security mec- nisms,militaryoperations,transportation-relatedapplications,etc.Atthesametime, new developments in hardware, software, and communication technologies are - panding these possibilities. As in any other technology, research brings new dev- opments and re nements and continuous improvements of current approaches that push the technology even further. Looking toward the future, the technology seems even more promising in two directions. First, a few years from now more powerful wireless sensor devices will be available, and wireless sensor networks will have applicability in an endless number of scenarios, as they will be able to handle traf c loads not possible today, make more computations, store more data, and live longer because of better energy sources. Second,a few years from now, the opposite scenario might also be possible. The availability of very constrained, nanotechnology-made wireless sensor devices will bring a whole new world of applications, as they will be able to operate in - vironments and places unimaginable today. These two scenarios, at the same time, will both bring new research challenges that are always welcome to researchers.
