CAD/CAM systems are perhaps the most crucial advancement in the field of new technology relating to engineering, design and drawing in all technical domains. CAD/CAM stands for computer-aided design and computer-aided manufacturing. These systems are useful in all facets of contemporary design and architecture. The fundamentals of CAD/CAM systems are covered in detail throughout this book. This book aims to introduce the fundamental aspects, complete with an adequate numberof illustrations and examples, without delving too deeply into the specifics of the subject matter. This book is valuable in the classroom for both teachers and students. Features Each chapter begins with the Learning Outcomes (LOs) section, which highlights the critical points of that chapter. All LOs, solved examples, and questions are mapped to six Bloom Taxonomy levels (BT levels). Offers fundamental concepts of CAD/CAM without becoming too complicated. Solved examples are presented in each section after the theoretical discussion to clarify the concept of that section. Chapter-end summaries reinforce key ideas and help readers recall the concepts discussed. Students and professionals need to have a working knowledge of CAD/CAM since it has many applications and continues to expand. Students at the undergraduate and graduate levels of engineering courses use this book as their primary textbook. It will also be helpful for managers, consultants, and professionals.

Recently, the prime focus of research across the globe is to develop advanced drug delivery systems to enhance their therapeutic potential and clinical safety and, to reduce the drawbacks associated with conventional drug formulations. Hydrogels are extremely reliable materials which have been explored for designing drug delivery (DD) systems because of their biocompatibility and physicochemical properties. The inherent properties of polymeric hydrogels which make them suitable for DD applications are controlled by their crosslinked network structures. Several theories and complex mathematical equations/models have been proposed to explain the network structure of the hydrogels. Their extensive knowledge is almost beyond the expertise of polymer chemists involved in designing of DD devices. Herein, simplifications of these equations have been carried out for their utilization to evaluate network parameters required to design hydrogels for DD devices. The significance of hydrogel swelling and its correlation with the various synthetic and physiochemical parameters and their influence on parameters of structural networking of hydrogel based DD systems have also been analyzed.
