Description: The hand is an agency of the brain; it reflects activities of the brain and thereby can be seen as a mirror to the mind. The dexterity of the hand has been investigated widely in developmental psychology and in anthropology. Since robotics launched in the mid-1970s, numerous multi-fingered hands mimicking the human hand have been designed and made in a number of universities and research institutes, in addition to sophisticated prosthetic hands with plural fingers.

Control Theory of Multi-fingered Hands presents a comprehensive insight into the intelligence and dexterity of robotic multi-fingered hands from both the physical and control- theoretic viewpoints.

The book:
focuses on the problem of how to control dexterous movements of fingers interacting with an object in the execution of everyday tasks;
clarifies what kinds of sensory-motor coordinated signals are necessary and sufficient for realising stable grasping and/or object manipulation, in particular, the synergistic choices of control gains in co-activation signals for finger muscles and tendons crucial in realising secure pinching motions;
derives a mathematical model of the dynamics of a complicated mechanism of multiple fingers with multiple joints physically interacting; and,
considers the problem of how to recreate the function of “blind grasping”.

Control Theory of Multi-fingered Hands will be a useful reference for postgraduate students and researchers in this field, as well as engineers and roboticists.

Description: This is the first comprehensive treatment of the three basic symmetries of probability theory - contractability, exchangeability, and rotatability - defined as invariance in distribution under contractions, permutations, and rotations. Originating with the pioneering work of de Finetti from the 1930’s, the theory has evolved into a unique body of deep, beautiful, and often surprising results, comprising the basic representations and invariance properties in one and several dimensions, and exhibiting some unexpected links between the various symmetries as well as to many other areas of modern probability. Most chapters require only some basic, graduate level probability theory, and should be accessible to any serious researchers and graduate students in probability and statistics. Parts of the book may also be of interest to pure and applied mathematicians in other areas. The exposition is formally self-contained, with detailed references provided for any deeper facts from real analysis or probability used in the book.

Description: In this book leading profesionals in the semiconductor microelectronics field discuss the future evolution of their profession. The following are some of the questions discussed:

Does CMOS technology have a real problem?
Do transistors have to be smaller or just better and made of better materials?
What is to come after semiconductors?
Superconductors or molecular conductors?
Is bottom-up self-assembling the answer to the limitation of top-down lithography?
Is it time for Optics to become a force in computer evolution?
Quantum Computing, Spintronics?
Where is the printable plastic electronics proposed 10 years ago?
Are carbon nanotube transistors the CMOS of the future?

Description: Model checking is a prominent technique used in the hardware and software industries for automatic verification. While it is very successful in finding subtle bugs in distributed systems, it faces the state explosion problem - the number of reachable states grows exponentially in the number of concurrent components.

In this book the authors introduce unfoldings, an approach to model checking which alleviates the state explosion problem by means of concurrency theory. They offer a gentle introduction to the basics of the method, and in particular they detail an unfolding-based algorithm for model checking concurrent systems against properties specified as formulas of linear temporal logic (LTL). Self-contained chapters cover transition systems and their products; unfolding products; search procedures for basic verification problems, such as reachability and livelocks; and model checking LTL. The final chapter summarizes the results of the book, and points the reader to tools and case studies.

The book will be of value to researchers and graduate students engaged in automatic verification and concurrency theory.

Description: Differential equations are a fast evolving branch of mathematics and one of the mathematical tools most used by scientists and engineers. This book gathers a collection of original articles and state-of-the-art contributions, written by highly distinguished researchers working in differential equations, delay-differential equations, differential inclusions, variational problems, Young measures, control theory, dynamical systems, chaotic systems and their relations with physical systems. The forefront of research in these areas is represented in this volume.

The book and all contributions are dedicated to Arrigo Cellina and James A. Yorke on their 65th anniversary. Their remarkable scientific career covered all the above areas and was one of the main driving forces behind the work of many of the authors and the editor of this volume.

For researchers and graduate students in mathematics, physics and engineering, the material in this book will be a valuable resource, and a tool for everyone working in differential equations, chaos and variational problems. It brings the reader to the frontiers of research in the areas mentioned above and will stimulate further research.

Description: The articles in this volume are devoted to:

- moduli of coherent sheaves;
- principal bundles and sheaves and their moduli;
- new insights into Geometric Invariant Theory;
- stacks of shtukas and their compactifications;
- algebraic cycles vs. commutative algebra;
- Thom polynomials of singularities;
- zero schemes of sections of vector bundles.

The main purpose is to give “friendly” introductions to the above topics through a series of comprehensive texts starting from a very elementary level and ending with a discussion of current research. In these texts, the reader will find classical results and methods as well as new ones. The book is addressed to researchers and graduate students in algebraic geometry, algebraic topology and singularity theory. Most of the material presented in the volume has not appeared in books before.

Description: The 3G IP Multimedia Subsystem (IMS): Merging the Internet and the Cellular Worlds, Second Edition is an updated version of the best-selling guide to this exciting technology that will merge the Internet with the cellular world, ensuring the availability of Internet technologies such as the web, email, instant messaging, presence and videoconferencing nearly everywhere. In this thoroughly revised overview of the IMS and its technologies, goals, history, vision, the organizations involved in its standardization and architecture, the authors first describe how each technology works on the Internet and then explain how the same technology is adapted to work in the IMS, enabling readers to take advantage of any current and future Internet service.

Key features of the Second Edition include:

* New chapter on Next Generation Networks, including an overview on standardization, the architecture, and PSTN/ISDN simulation services.
* Fully updated chapter on the Push-to-talk over Cellular (PoC) service, covering the standardization in the Open Mobile Alliance (OMA), architecture, PoC session types, user plane, and the Talk Burst Control Protocol.
* Several expanded sections, including discussion of the role of the Open Mobile Alliance in the standardization process, IPv4 support in IMS, a description of the IMS Application Layer Gateway and the Transition Gateway, and a description of the presence data model.
* Updated material on the presence service, session-based instant messages with the Message Session Relay Protocol (MSRP), and the XML Configuration Access Protocol (XCAP).
* Supported by a companion website on which instructors and lecturers can find electronic versions of the figures.
