This book is all about the systems and structures, technical advances in smart materials, including materials, sensing and actuation, optics and electromagnetics, structures, control and information processing. The HRD field is multidisciplinary, it requires practitioners to have a working knowledge of a variety of topics. However, many professionals in the field at this time do not have formal preparation in some of these significant areas. Often, trainers are chosen simply because they are subject-matter experts. They must find many resources, such as books, magazines, and workshops, to obtain the necessary background to help them perform the many functions of their new role effectively. Those practitioners who do attend academic programs may find that there is so much information to be covered that there is time only for a cursory look at many of the topics, especially in regard to training and development issues. This book will help new practitioners who want to develop a working knowledge of the field, as well as an opportunity for long-time practitioners to examine various experts’ views in one convenient package. It is intended that this book will prove to be useful reference to the practitioners on this field.
