The theme of this book is sustainable e-waste management through effective amalgamation of information and communication technologies (ICT) and green recycling technologies to ensure development of intelligent, smart, and sustainable systems supported by recent case studies from OEMs, IT industries as well as E-waste recyclers.

A term referring to a heterogeneous group of hygienic, diagnostic, and therapeutic philosophies and practices whose principles and techniques diverge from those of modern scientific medicine. Some of these differ from traditional medicine only in preferring natural hygienic and therapeutic methods to drug treatment and surgery; some have roots in ancient or modern philosophical or religious systems; and some are based on what some more clinically oriented critics assert are naive, false, or inconsistent notions of anatomy, physiology, psychology, pathology, and pharmacology. Complementary and alternative medicine, or CAM, is a category of medicine that includes a variety of treatment approaches that fall outside the realm of conventional medicine. An increasing amount of research is being done to establish the safety and efficacy of alternative medicine.

This book constitutes the refereed proceedings of the 9th International Conference on Cryptology in India, INDOCRYPT 2008, held in Kharagpur, India, in December 2008.The 33 revised full papers were carefully reviewed and selected from 111 submissions. The papers are organized in topical sections on stream ciphers, cryptographic hash functions, public-key cryptography, security protocols, hardware attacks, block ciphers, cryptographic hardware, elliptic curve cryptography, and threshold cryptography.

This book presents a socio-economic analysis of the issues linking technological innovation in providing arsenic-safe drinking water in rural areas.

Offering readers a wealth of cutting-edge, Riccati-based design techniques for various forms of control, this self-contained text stress-tests the reliability of the methods outlined with rigorous stability analyses and detailed control design algorithms.

Developed from the author¿s popular graduate-level course, this self-contained text presents a complete treatment of number-theoretic algorithms. Avoiding advanced algebra and requiring no prior experience with number theory or sophisticated algebraic tools, the book covers many computational aspects of number theory and highlights important and interesting engineering applications. With an emphasis on implementation issues, it uses the freely available number-theory calculator GP/PARI to demonstrate complex arithmetic computations. The text includes numerous examples and exercises throughout and omits lengthy proofs, making the material accessible to students and practitioners.
