Having trouble deciding which coding scheme to employ, how to design a new scheme, or how to improve an existing system? This summary of the state-of-the-art in iterative coding makes this decision more straightforward. With emphasis on the underlying theory, techniques to analyse and design practical iterative coding systems are presented. Using Gallager's original ensemble of LDPC codes, the basic concepts are extended for several general codes, including the practically important class of turbo codes. The simplicity of the binary erasure channel is exploited to develop analytical techniques and intuition, which are then applied to general channel models. A chapter on factor graphs helps to unify the important topics of information theory, coding and communication theory. Covering the most recent advances, this text is ideal for graduate students in electrical engineering and computer science, and practitioners.

With 80 Plates Originally Published between 1828 and 1855 In the nineteenth century students who did not have access to plaster casts and teachers who wished for a course of instruction turned to copy books for drawing lessons. They were popular and many authors produced versions either for use in schools or for learning at home. This book combines examples from seven different books. The selections focus on those sections of the books devoted to drawing the human figure. The books include: Buchanan's Initiatory Drawing Lessons The Illustrated Drawing Book The Young Artists Assistant in the Art of Drawing A Guide to Figure Drawing Oxford Drawing Book Drawing Lessons for Family and School Systematische Zeichen Schule

In 1683 Gerard Audran published a work entitled "Les Proportions du corps humain mesures sur les plus belles figures de l'antiquite." The illustrations are of the most famous antique sculptures with careful measurements of each. This book reviews that work from the perspective of his contemporaries and subsequent commentators and translates his words into English as well as reprinting his original plates for the modern student, and providing some additional illustrations which help you to enjoy the plates on proportion.

This book is based on the figure drawing notebook of a young student in Philadelphia in 1927 and 1928. It illustrates the methods of drawing the figure which were used at the time, and will be interesting to anyone learning to draw the figure today. The drawings show the work of a confident and talented artist who was studying a new course of drawing from the figure. Formerly students at the school had draw from casts and prints and studied the rules of perspective. The book includes all the drawings from Grace Young's notebook plus examples of the knowledge of figure drawing from the time.

This book of prints of the human head, showing the range of emotions and expressions, were engraved by the most skilled artists of the day from tracings and drawings made by Nicholas Dorigny from the famous cartoons that Raphael designed in the early 1500s to be made into tapestries for the Sistine Chapel.

This guide to the proportions of the human form is a reformatted reproduction of the famous but hard to find work by Johann Gottfried Shadow. It includes images of plates engraved by John Sutcliffe from the English translation, and images of the original German plates. The original was a huge book, each plate was 24" by 19" for this version the large plates were photographed to reproduce them on a single page, but also reproduced in sections so they can be seen as large as possible. It includes an introduction, a history of the study of human proportion and a description of the plates plus the original German plates reproduced on single pages. Schadow based based his work on the pioneering work of the Greek Sculptor Polycletus who both wrote a treatise on human proportion and sculpted a figure to illustrate his work. Polycletus was among the creators of classical Greek sculpture, famous for his naturalism.
