After two decades of research and development, elliptic curve cryptography now has widespread exposure and acceptance. Industry, banking, and government standards are in place to facilitate extensive deployment of this efficient public-key mechanism. This guide explains the basic mathematics, describes state-of-the-art implementation methods, and presents standardized protocols for public-key encryption, digital signatures, and key establishment. In addition, the book addresses some issues that arise in software and hardware implementation, as well as side-channel attacks and countermeasures. Readers receive the theoretical fundamentals as an underpinning for a wealth of practical and accessible knowledge about efficient application.
This straightforward and practical guide takes the reader step-by-step through a PR campaign.

This completely updated second edition includes new information on professional advisers, spin-doctors, PR in local government and financial PR.
Learning Science these days is much more about solving practical problems by doing investigations. At the same time, there is much less emphasis at the early stages on acquiring specialist knowledge than there used to be. This book sets out to help top primary and lower secondary pupils learn the skills of practical investigation, whilst minimising the teachers’ need to collect, prepare or purchase materials, a job which takes up more time and resources than most teachers can reasonably spare at present. The double-page ‘self-teaching’ units take one skill or topic at a time, and use only the kind of materials you could find in any classroom or home. Childrens’ immediate surroundings are made use of wherever possible.
With this valuable practical guide, three members of the Harvard Stem Cell Institute have compiled and edited the definite handbook for the exciting new field of human embryonic stem cell research. The editors have gathered protocols from scientists with extensive reputation and expertise, describing and comparing currently used techniques for the culture of human stem cells and discussing the strengths and weaknesses of the different approaches. Human Embryonic Stem Cells: The Practical Handbook contains the first centralised collection of methods used in human embryonic stem cell biology. The book covers the derivation of human stem cell lines, the obtaining of cells from human stem cell banks, the culturing and characterisation of the cells, and the differentiation of the cells in vitro and in vivo.
Interactive products designed for childrenwhether toys, games, educational products, or websitesare increasingly embedded in childrens lives and school experiences. Making these products safe, effective, and entertaining requires new methodologies for carrying out sound and unbiased evaluations for these users with unique requirements, environments, and ethical considerations.
This book directly addresses this need by thoroughly covering the evaluation of all types of interactive technology for children. Based on the authors' workshops, conference courses, and own design experience and research, this highly practical book reads like a handbook, while being thoroughly grounded in the latest research. Throughout, the authors illustrate techniques and principles with numerous mini case studies and highlight practical information in tips and exercises and conclude with three in-depth case studies. Essential reading for usability experts, product developers, and researchers in the field.
