This is not a traditional work on topological graph theory. No current graph or voltage graph adorns its pages. Its readers will not compute the genus (orientable or non-orientable) of a single non-planar graph. Their muscles will not flex under the strain of lifting walks from base graphs to derived graphs. What is it, then? It is an attempt to place topological graph theory on a purely combinatorial yet rigorous footing. The vehicle chosen for this purpose is the con cept of a 3-graph, which is a combinatorial generalisation of an imbedding. These properly edge-coloured cubic graphs are used to classify surfaces, to generalise the Jordan curve theorem, and to prove Mac Lane's characterisation of planar graphs. Thus they playa central role in this book, but it is not being suggested that they are necessarily the most effective tool in areas of topological graph theory not dealt with in this volume. Fruitful though 3-graphs have been for our investigations, other jewels must be examined with a different lens. The sole requirement for understanding the logical development in this book is some elementary knowledge of vector spaces over the field Z2 of residue classes modulo 2. Groups are occasionally mentioned, but no expertise in group theory is required. The treatment will be appreciated best, however, by readers acquainted with topology. A modicum of topology is required in order to comprehend much of the motivation we supply for some of the concepts introduced.
Charles Edge, Zack Smith, and Beau Hunter provide detailed explanations of the technology required for large-scale Mac OS X deployments and show you how to integrate it with other operating systems and applications. Enterprise Mac Administrator's Guide addresses the growing size and spread of Mac OS X deployments in corporations and institutions worldwide. In some cases, this is due to the growth of traditional Mac environments, but for the most part it has to do with "switcher" campaigns, where Windows and/or Linux environments are migrating to Mac OS X. However, there is a steep culture shock with these types of migrations. The products that are used are different, the nomenclature is different, and most importantly the best practices for dealing with the operating system are different. Apple provides a number of tools to help automate and guide IT toward managing a large number of Mac OS X computers—it has since before Mac OS X was initially released. However, if you want to put together all of the pieces to tell a compelling story about how to run an IT department or a deployment of Macs, you need to compile information from a number of different sources. This book will provide explanations of the technology required. Provides complete solutions for the large- and medium-scale integration of directory services, imaging, and security Complete guide for integrating Macs and Mac OS X into mixed environments with confidence and no down time One-stop volume for IT professionals who need the technical details to get their job done as efficiently and effectively as possible

In the decades since his execution by the Nazis in 1945, Dietrich Bonhoeffer, the German pastor, theologian, and anti-Hitler conspirator, has become one of the most widely read and inspiring Christian thinkers of our time. Now, drawing on extensive new research, Strange Glory offers a definitive account, by turns majestic and intimate, of this modern icon. The scion of a grand family that rarely went to church, Dietrich decided as a thirteen-year-old to become a theologian. By twenty-one, the rather snobbish and awkward young man had already written a dissertation hailed by Karl Barth as a “theological miracle.” But it was only the first step in a lifelong effort to recover an authentic and orthodox Christianity from the dilutions of liberal Protestantism and the modern idolatries of blood and nation—which forces had left the German church completely helpless against the onslaught of Nazism. From the start, Bonhoeffer insisted that the essence of Christianity was not its abstract precepts but the concrete reality of the shared life in Christ. In 1930, his search for that true fellowship led Bonhoeffer to America for ten fateful months in the company of social reformers, Harlem churchmen, and public intellectuals. Energized by the lived faith he had seen, he would now begin to make what he later saw as his definitive “turn from the phraseological to the real.” He went home with renewed vocation and took up ministry among Berlin’s downtrodden while trying to find his place in the hoary academic establishment increasingly captive to nationalist fervor. With the rise of Hitler, however, Bonhoeffer’s journey took yet another turn. The German church was Nazified, along with every other state-sponsored institution. But it was the Nuremberg laws that set Bonhoeffer’s earthly life on an ineluctable path toward destruction. His denunciation of the race statutes as heresy and his insistence on the church’s moral obligation to defend all victims of state violence, regardless of race or religion, alienated him from what would become the Reich church and even some fellow resistors. Soon the twenty-seven-year-old pastor was one of the most conspicuous dissidents in Germany. He would carry on subverting the regime and bearing Christian witness, whether in the pastorate he assumed in London, the Pomeranian monastery he established to train dissenting ministers, or in the worldwide ecumenical movement. Increasingly, though, Bonhoeffer would find himself a voice crying in the wilderness, until, finally, he understood that true moral responsibility obliged him to commit treason, for which he would pay with his life. Charles Marsh brings Bonhoeffer to life in his full complexity for the first time. With a keen understanding of the multifaceted writings, often misunderstood, as well as the imperfect man behind the saintly image, here is a nuanced, exhilarating, and often heartrending portrait that lays bare Bonhoeffer’s flaws and inner torment, as well as the friendships and the faith that sustained and finally redeemed him. Strange Glory is a momentous achievement.

The latest edition of the essential text and professional reference, with substantial new material on such topics as vEB trees, multithreaded algorithms, dynamic programming, and edge-based flow. Some books on algorithms are rigorous but incomplete; others cover masses of material but lack rigor. Introduction to Algorithms uniquely combines rigor and comprehensiveness. The book covers a broad range of algorithms in depth, yet makes their design and analysis accessible to all levels of readers. Each chapter is relatively self-contained and can be used as a unit of study. The algorithms are described in English and in a pseudocode designed to be readable by anyone who has done a little programming. The explanations have been kept elementary without sacrificing depth of coverage or mathematical rigor. The first edition became a widely used text in universities worldwide as well as the standard reference for professionals. The second edition featured new chapters on the role of algorithms, probabilistic analysis and randomized algorithms, and linear programming. The third edition has been revised and updated throughout. It includes two completely new chapters, on van Emde Boas trees and multithreaded algorithms, substantial additions to the chapter on recurrence (now called “Divide-and-Conquer”), and an appendix on matrices.

Regarded as one of the most outstanding commanding officers on the Western Front, Wilfrid Abel Smith commanded an elite unit of 1,000 of the finest soldiers in the British Army. Educated at Eton and Sandhurst, Smith was a career soldier who led his battalion of Grenadiers with distinction through the First Battle of Ypres and the winter trench warfare of 1914–15. He died of wounds received at the Battle of Festubert in May 1915.The letters and diaries provide a vivid, first-hand account of the fighting and suffering on the front line, written by a compassionate commander and affectionate family man. Most of his brother officers were Old Etonians, including his brigade commander, Lord Cavan, and his second-in-command, George ‘Ma’ Jeffreys. Smith’s account offers a poignant insight into the way in which the privileged world of a Guards officer responded, with the highest sense of duty and courage, to the unprecedented demands of industrial warfare.From Eton to Ypres is edited by his great-grandson, Charles Abel Smith.
