Bringing together an unprecedented number of extensive personal stories, this book shares the triumphs and heartbreaking moments experienced by some of the first Cubans to come to the United States after Fidel Castro took power in 1959.

The History Of Wales. : Comprehending The Lives And Succession Of The Princes Of Wales, From Cadwalader The Last King, To Lhewelyn The Last Prince, Of British Blood. : With A Short Account Of The Affairs Of Wales, Under The Kings Of England. has been considered by academicians and scholars of great significance and value to literature.

The design of computer systems to be embedded in critical real-time applications is a complex task. Such systems must not only guarantee to meet hard real-time deadlines imposed by their physical environment, they must guarantee to do so dependably, despite both physical faults (in hardware) and design faults (in hardware or software). A fault-tolerance approach is mandatory for these guarantees to be commensurate with the safety and reliability requirements of many life- and mission-critical applications. This book explains the motivations and the results of a collaborative project', whose objective was to significantly decrease the lifecycle costs of such fault­ tolerant systems. The end-user companies participating in this project already deploy fault-tolerant systems in critical railway, space and nuclear-propulsion applications. However, these are proprietary systems whose architectures have been tailored to meet domain-specific requirements. This has led to very costly, inflexible, and often hardware-intensive solutions that, by the time they are developed, validated and certified for use in the field, can already be out-of-date in terms of their underlying hardware and software technology.

Delta-4 is a 5-nation, 13-partner project that has been investigating the achievement of dependability in open distributed systems, including real-time systems. This book describes the design and validation of the distributed fault-tolerant architecture developed within this project. The key features of the Delta-4 architecture are: (a) a distributed object-oriented application support environment; (b) built-in support for user-transparent fault- tolerance; (c) use of multicast or group communication protocols; and (d) use of standard off- the-shelf processors and standard local area network technology with minimum specialized hardware. The book is organized as follows: The first 3 chapters give an overview of the architecture's objectives and of the architecture itself, and compare the proposed solutions with other approaches. Chapters 4 to 12 give a more detailed insight into the Delta-4 architectural concepts. Chapters 4 and 5 are devoted to providing a firm set of general concepts and terminology regarding dependable and real-time computing. Chapter 6 is centred on fault-tolerance techniques based on distribution. The description of the architecture itself commences with a description of the Delta-4 application support environment (Deltase) in chapter 7. Two variants of the architecture - the Delta-4 Open System Architecture (OSA) and the Delta-4 Extra Performance Architecture (XPA) - are described respectively in chapters 8 and 9. Both variants of the architecture have a common underlying basis for dependable multicasting, i. e.

Bringing together personal stories, this book shares the triumphs and heartbreaking moments experienced by some of the first Cubans to come to the US after Fidel Castro took power. This is a moving look inside fifteen years of migration that changed the two countries and transformed the lives of the people separated from their homeland.

David Powell, through impeccable research and creativity, waves a tapestry of temptation using the bad guys in the Book of Mormon. Political unrest, government corruption, assassinations, bloody wars, moral decay, pride, greed, and unspeakable evil, all are revealed within, showing clearly how the Book of Mormon is indeed a work for us in the latter days. David makes it possible for anyone to understand what is in store for those who decide or allow themselves to be a bad boy (or girl) in these times. Bad Boys of the Book of Mormon is a must for Seminary students and teachers, Institute students and teachers, Sunday School students and teachers, and anyone else who is seeking truth. Choose ye this day whom ye will serve."e; (Alma 30:8) This book makes clear, with great originality and ingenuity, what happens to those who choose evil. You will find it interesting, informative and intriguing. "e;

Complete with original maps, photos, and the skillful writing readers have come to expect, this book delves into all the issues, analyzing the campaign from an operational standpoint.

A collection of essays, this book chronicles the history of dissent in the British Isles, since Magna Carta. It covers such milestones as the age of revolution, industrialisation and the foundation of the Labour Party.

Battle above the Clouds by David Powell recounts the first half of the campaign to lift the siege of Chattanooga and one of the most dramatic battles of the entire war: Lookout Mountain.

This volume examines the main controversies of the Edwardian period in an attempt to assess the nature and seriousness of the Edwardian crisis, relating the discussion to current historiographical debates on topics such as the vitality of Edwardian liberalism and the importance of feminism.
