Channel coding lies at the heart of digital communication and data storage, and this detailed introduction describes the core theory as well as decoding algorithms, implementation details, and performance analyses. In this 2009 book, Professors Ryan and Lin provide clear information on modern channel codes, including turbo and low-density parity-check (LDPC) codes. They also pr...(展开全部)

Experiment with cryptography—the science of secret writing. Cipher and decipher codes: transposition and polyalphabetical ciphers, famous codes, typewriter and telephone codes, codes that use playing cards, knots, and swizzle sticks...even invisible writing and sending messages through outer space. Hours of intrigue and challenge. 45 diagrams.

意大利知名史学家，被誉为“古典世界历史文献的首席学者”，1936年成为Turin大学的罗马史教授，但是作为一个犹太人，不久就失去了教席并移居英国（1938年），继续任教于牛津大学、伦敦大学学院（1951-1975），也经常访问芝加哥大学等。除了研究古代希腊历史和它的方法论，莫米利亚诺对现代史学也颇感兴趣（比如吉本），撰写了大量相关的研究。

This book is an introduction to a new rapidly developing theory of quantum computing. It begins with the basics of classical theory of computation: Turing machines, Boolean circuits, parallel algorithms, probabilistic computation, NP-complete problems, and the idea of complexity of an algorithm. The second part of the book provides an exposition of quantum computation theory. I...(展开全部)

Christianity and Classical Culture is considered one of the great works of scholarship published in the last century. The theme of Christianity and Classical Culture is the fundamental change in thought and action that occurred from the reign of Augustus to the time of Augustine. The classical world sought to practice politics and understand the world in purely rational terms, ...(展开全部)
