Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This book evaluates the life and empire of the pivotal yet controversial Byzantine emperor Heraclius (ad. 610-641), a contemporary of the Prophet Muhammad. His stormy war-torn reign is critical for understanding the background to fundamental changes in the Balkans and the Middle East, including the emergence of Islam. Heraclius' skills enabled him to capture and recapture important territory, including Jerusalem, Syria and Egypt. Yet, they proved to be of little value when he confronted early Islamic conquests.

This book addresses the question of how system software should be designed to account for faults, and which fault tolerance features it should provide for highest reliability. With this second edition of Software Design for Resilient Computer Systems the book is thoroughly updated to contain the newest advice regarding software resilience. With additional chapters on computer system performance and system resilience, as well as online resources, the new edition is ideal for researchers and industry professionals. The authors first show how the system software interacts with the hardware to tolerate faults. They analyze and further develop the theory of fault tolerance to understand the different ways to increase the reliability of a system, with special attention on the role of system software in this process. They further develop the general algorithm of fault tolerance (GAFT) with its three main processes: hardware checking, preparation for recovery, and the recovery procedure. For each of the three processes, they analyze the requirements and properties theoretically and give possible implementation scenarios and system software support required. Based on the theoretical results, the authors derive an Oberon-based programming language with direct support of the three processes of GAFT. In the last part of this book, they introduce a simulator, using it as a proof of concept implementation of a novel fault tolerant processor architecture (ERRIC) and its newly developed runtime system feature-wise and performance-wise. Due to the wide reaching nature of the content, this book applies to a host of industries and research areas, including military, aviation, intensive health care, industrial control, and space exploration.

Who lost' Christian North Africa? Who won it and how? Walter Kaegi takes a fresh look at these perennial questions, with maps and on-site observations, in this exciting new book. Persisting clouds of suspicion and blame overshadowed many Byzantine attempts to defend North Africa, as Byzantines failed to meet the multiple challenges from different directions which ultimately overwhelmed them. While the Muslims forcefully and permanently turned Byzantine internal dynastic and religious problems and military unrest to their advantage, they brought their own strengths to a dynamic process that would take a long time to complete the transformation of North Africa. An impartial comparative framework helps to sort through identity politics, Orientalism' charges and counter-charges, and institutional controversies; this book also includes a new study of the decisive battle of Sbeitla in 647, helping readers to understand what befell Byzantium, and indeed empires from Rome to the present."

This is a study of how and why the Byzantine empire lost many of its most valuable provinces to Islamic conquerors in the seventh century, provinces that included Syria, Palestine, Mesopotamia and Armenia. It investigates conditions on the eve of those conquests, mistakes in Byzantine policy toward the Muslims, the course of the military campaigns, and the problem of local official and civilian collaboration with the Muslims. It also seeks to explain how after some terrible losses the Byzantine government achieved some intellectual rationalization of its disasters and began the complex process of transforming and adapting its fiscal and military institutions and political controls in order to prevent further disintegration.

This book evaluates the life and empire of the pivotal yet controversial and poorly understood Byzantine emperor Heraclius (AD 610-641), a contemporary of the Prophet Muhammad. Heraclius' reign is critical for understanding the background to fundamental changes in the Balkans and the Middle East, including the emergence of Islam, at the end of antiquity. Heraclius captured and lost important swathes of territory, including Jerusalem and Syria and Egypt. Skills in exploiting divisions within the ranks of his opponents, and encouraging the switching of sides and the breakdown of morale, provided Heraclius with his greatest triumphs, yet they proved to be of little value when he finally confronted the early Islamic conquests. The author synthesizes diverse primary sources, including those in Greek and Arabic, in the light of more recent historical scholarship. The varied Mediterranean and Middle Eastern context stretches from North Africa to Syria, Armenia and what is modern Iraq.

The Greek-German school dictionary developed in the second half of the 19th century by Gustav Eduard Benseler, is still an essential reference work today, thanks especially to the last extensive revision in 1931. The main content of the dictionary was based on the works of Homer, Herodotus, Aischylos, Sophokles, Euripides, Thucydides, Xenophon, Plato, Lysias and the New Testament.

The University of Chicago Readings in Western Civilization (nine volumes) makes available to students and teachers a unique selection of primary documents, many in new translations. These readings, prepared for the highly praised Western civilization sequence at the University of Chicago, were chosen by an outstanding group of scholars whose experience teaching that course spans almost four decades. Each volume includes rarely anthologized selections as well as standard, more familiar texts; a bibliography of recommended parallel readings; and introductions providing background for the selections. Beginning with Periclean Athens and concluding with twentieth-century Europe, these source materials enable teachers and students to explore a variety of critical approaches to important events and themes in Western history.
Individual volumes provide essential background reading for courses covering specific eras and periods. The complete nine-volume series is ideal for general courses in history and Western civilization sequences.

Professor Kaegi studies the response of the eastern half of the Roman Empire to the disintegration of western Rome, usually dated from the sack of the city of Rome in A.D. 410. Using sources from the fifth and sixth centuries, he shows that the eastern empire had a clear awareness of, interest in, and definite opinions on the disasters that befell Rome in the west. Religious arguments, both Pagan and Christian, tended to dominate the thinking of the intellectuals, but economic and diplomatic activity also contributed to the reaction. This reaction, the author finds, was in a distinctly eastern manner and reflected quite naturally the special conditions prevailing in the eastern provinces. Originally published in 1968. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
