In recent years, with the rapid growth of the Internet, the bandwidth demand for data traffic is exploding. Optical networks based on wavelength-division multiplexing (WDM) technology offer the promise to satisfy the bandwidth requirements of the Internet infrastructure. With WDM technology, signals are carried simultaneously on mUltiple wavelengths on a single fiber. WDM provides a practical approach of resolving the mismatch between the fiber ca pacity and the peak electronic processing speed. Mesh-based WDM networks have recently attracted much research and development interest since the In ternet topology is meshed in nature, and more importantly, mesh-based WDM networks are flexible with respect to routing and survivability. This book exam ines the management and survivability issues of mesh-based WDM networks and proposes new WDM network protocols and algorithms that could make telecommunication networks more efficient. Wavelength-routing has been one of the most important technologies to em ploy WDM in backbone networks. In wavelength-routed WDM networks, optical channels, which are referred to as lightpaths, are set up between WDM terminals. Most chapters of this bock are focused on various issues related to wavelength-routed networks, namely, routing and wavelength-assignment, con trol and management, fault management, and wavelength-converter placement. This book also presents an all-optical packet-switched network architecture based on the concept of photonic slot routing. The audience for this book are network designers and planners, research and development engineers active in the field of telecommunications, and students of optical networking at the graduate or senior undergraduate levels."

Switched-Current Design and Implementation of Oversampling A/D Converters discusses the switched-current (SI) technique and its application in oversampling A/D converters design. The SI technique is an analog sampled-data technique that fully exploits the digital CMOS process. Compared with the traditional switched-capacitor (SC) technique, the SI technique has both pros and cons that are highlighted in the book. With the consideration of similarity and difference of SI and SC techniques, oversampling A/D converter architectures are tailored and optimized for SI design and implementation in the book. Switched-Current Design and Implementation of Oversampling A/D Converters emphasizes the practical aspects of SI circuits without tedious mathematical derivations, and is full of circuit design and implementation examples. There are more than 10 different chips included in the book, demonstrating the high-speed (over 100 MHz) and ultra-low-voltage (1.2 V) operation of SI circuits and systems in standard digital CMOS processes. Therefore, the book is of special value as a practical guide for designing SI circuits and SI oversampling A/D converters. Switched-Current Design and Implementation of Oversampling A/D Converters serves as an excellent reference for analog designers, especially A/D converter designers, and is of interest to digital designers for real-time signal processing who need A/D interfaces. The book may also be used as a text for advanced courses on the subject.

A major challenge in grid computing remains the application software development for this new kind of infrastructure. Grid application programmers have to take into account several complicated aspects: distribution of data and computations, parallel computations on different sites and processors, heterogeneity of the involved computers, load balancing, etc. Grid programmers thus demand novel programming methodologies that abstract over such technical details while preserving the beneficial features of modern grid middleware. For this purpose, the authors introduce Higher-Order Components (HOCs). HOCs implement generic parallel/distributed processing patterns, together with the required middleware support, and they are offered to users via a high-level service interface. Users only have to provide the application-specific pieces of their programs as parameters, while low-level implementation details, such as the transfer of data across the grid, are handled by the HOCs. HOCs were developed within the CoreGRID European Network of Excellence and have become an optional extension of the popular Globus middleware. The book provides the reader with hands-on experience, describing a broad collection of example applications from various fields of science and engineering, including biology, physics, etc. The Java code for these examples is provided online, complementing the book. The expected application performance is studied and reported for extensive performance experiments on different testbeds, including grids with worldwide distribution. The book is targeted at graduate students, advanced professionals, and researchers in both academia and industry. Readers can raise their level of knowledge about methodologies for programming contemporary parallel and distributed systems, and, furthermore, they can gain practical experience in using distributed software. Practical examples show how the complementary online material can easily be adopted in various new projects.

This book is devoted to logic synthesis and design techniques for asynchronous circuits. It uses the mathematical theory of Petri Nets and asynchronous automata to develop practical algorithms implemented in a public domain CAD tool. Asynchronous circuits have so far been designed mostly by hand, and are thus much less common than their synchronous counterparts, which have enjoyed a high level of design automation since the mid-1970s. Asynchronous circuits, on the other hand, can be very useful to tackle clock distribution, modularity, power dissipation and electro-magnetic interference in digital integrated circuits. This book provides the foundation needed for CAD-assisted design of such circuits, and can also be used as the basis for a graduate course on logic design.

The volume provides a comprehensive, up-to-date account on recent developments concerning the incorporation of fuzzy capabilities in Petri Net models. The results of such studies originated the class of models that have been designated by Fuzzy Petri Nets. The recent papers specially elaborated for this volume range over several aspects of fuzziness in Petri nets. They form an interesting collection of original works that covers a great variety of relevant problems concerning the concept of Fuzzy Petri Net model. The articles approach several of the most outstanding issues in the framework of Fuzzy Petri nets, such as the representation of time, consistency checking, learning, design, computational efficiency, modelling flexibility, among others. From the material collected in the book one can extract the points of view of leading researchers concerning the basic and advanced concepts, advantages, potential applications and open problems, related to the field.
