Could an Irish monk in the sixth century really have sailed all the way across the Atlantic in a small open boat, thus beating Columbus to the New World by almost a thousand years? Relying on the medieval text of St. Brendan, award-winning adventure writer Tim Severin painstakingly researched and built a boat identical to the leather curragh that carried Brendan on his epic voyage. He found a centuries-old, family-run tannery to prepare the ox hides in the medieval way; he undertook an exhaustive search for skilled harness makers (the only people who would know how to stitch the three-quarter-inch-thick hides together); he located one of the last pieces of Irish-grown timber tall enough to make the mainmast. But his courage and resourcefulness were truly tested on the open seas, including one heart-pounding episode when he and his crew repaired a dangerous tear in the leather hull by hanging over the side--their heads sometimes submerged under the freezing waves--to restitch the leather. A modern classic in the tradition of Kon-Tiki, The Brendan Voyage seamlessly blends high adventure and historical relevance. It has been translated into twenty-seven languages since its original publication in 1978. With a new Introduction by Malachy McCourt, author of A Monk Swimming

The numerical, discrete element, Discontinuous Deformation Analysis (DDA) method was developed by Dr. Gen-hua Shi while he was working at the University of California, Berkeley, under the supervision of Prof. Richard E. Goodman in the late 1980s. Two-dimensional DDA was published in 1993 and three-dimensional DDA in 2001. Since its publication DDA has been verified, validated and applied in numerous studies worldwide and is now considered a powerful and robust method to address both static and dynamic engineering problems in discontinuous rock masses. In this book Yossef H. Hatzor and Guowei Ma, co-chairs of the International Society for Rock Mechanics (ISRM) Commission on DDA, join Dr. Shi in authoring a monograph that presents the state of the art in DDA research. A comprehensive discussion of DDA development since its publication is provided in Chapter 1, followed by concise reviews of 2D and 3D DDA in chapters 2 and 3. Procedures to select geological and numerical input parameters for DDA are discussed in Chapter 4, and DDA validation and verification is presented in Chapter 5. Applications of DDA in underground and rock slope engineering projects are discussed in chapters 6 and 7. In Chapter 8 the novel contact theory recently developed by Dr. Shi is published in its complete form, for the first time. This book is published within the framework of the ISRM Book Series and is the contribution of the ISRM DDA Commission to the international rock mechanics community.

The International Conference on Complex Systems provides a unique opportunity for scientists to rise above the disciplinary boundaries and explore unity in complex systems. This volume contains the proceedings of the Second International Conference on Complex Systems. The sessions ranged from the opening talk by Nobel laureate Philip Anderson on emergence and the relevance of complex systems to physics to the final panel that included many of the great management gurus of this generation. The plenary session topics for the second conference were emergence, description and modeling, self-organization, networks, time series, agents in action, and complexity and management. Talks in these sessions often focused on contributions in specific disciplines, but each session contained a diverse set of disciplines to show the strategies and concepts that can be applied generally to complex systems. Overall, the conference presentations dealt with issues of significant public interest, including individual psychology, dynamics of social and economic change, the human genome, and ecology.The New England Complex Systems Institute is an independent educational and research institution dedicated to advancing the study of complex systems, including new concepts and methodologies that are affecting all fields of science and engineering, and are being applied to technology, business, and even social policy. NECSI organizes conferences, workshops, short courses, and other activities from which books will be produced for the NECSI Series on Complexity. The books will range from conference proceedings and graduate textbooks to general-audience trade books, and will address fundamental concepts, new frontiers, and innovative applications of complex systems.

The purpose of this book is to present some new methods in the treatment of partial differential equations. Some of these methods lead to effective numerical algorithms when combined with the digital computer. Also presented is a useful chapter on Green's functions which generalizes, after an introduction, to new methods of obtaining Green's functions for partial differential operators. Finally some very new material is presented on solving partial differential equations by Adomian's decomposition methodology. This method can yield realistic computable solutions for linear or non linear cases even for strong nonlinearities, and also for deterministic or stochastic cases - again even if strong stochasticity is involved. Some interesting examples are discussed here and are to be followed by a book dealing with frontier applications in physics and engineering. In Chapter I, it is shown that a use of positive operators can lead to monotone convergence for various classes of nonlinear partial differential equations. In Chapter II, the utility of conservation technique is shown. These techniques are suggested by physical principles. In Chapter III, it is shown that dyn~mic programming applied to variational problems leads to interesting classes of nonlinear partial differential equations. In Chapter IV, this is investigated in greater detail. In Chapter V, we show. that the use of a transformation suggested by dynamic programming leads to a new method of successive approximations.

In her long-anticipated fourth collection, The Engineers , Katy Lederer draws on the newfangled languages of reproductive technology, genetic engineering, and global warming to ask the age-old questions: What is "the self"? What is "the other"? And how to reproduce "one's self"? In poems that are both lyrical and playfully autobiographical, Lederer imagines form as a kind of genetics, synthesizing lines out of a rigorous constraint. Things can go wrong. The body--or poem--malfunctions, evacuating crucial parts of itself (miscarriage), or growing too aggressively or quickly (cancer). The body--or poem--attacks or even eats itself (autoimmune dysfunction; autophagy). Written almost entirely in the choral "we," the poems move among the perspectives of the bewildered parent, the unborn child, and the inscrutable God who looks down upon the human world. In a post-Roe landscape, the poems complicate and ultimately refashion our pre-conceived notions of the self--and of life. Radical, uncanny, and stunningly original, The Engineers takes us on a journey to a place we've never been, but that is hauntingly familiar.

The book starts with a background story of the author which explains what led him to his strange life- long hobby of "collecting religions". It then continues by building a systematic foundation to his Exodus theory. It starts with a closely related descriptions of North African history, geography, climate, the Africans, Egypt, and its powerful Nile in ancient times. The author then tells the story of his experiences in Africa, which led him to start his investigation and come up with the theory that the Exodus was partially occurred in North Africa. The book supports the theory with rational proofs including military, engineering, leadership, and common-sense explanations to many mystical stories about the Exodus, including the 10 plaques, crossing the sea of reeds, the reasoning for moving west, the locations of mount Sinai and its volcano "pillar of fire", the Tombs of Lust, the snakes attack in the Valley of the Serpents, the Manna tree, the golden Calf, the construction of the large Ark of Covenant and more. In addition, the author supports his theory by identifying 20 locations, which are listed in the Bible through which the Israelites passed from Egypt to Canaan, that still exist in North Africa today. Finally, the author brings additional evidence in support of his theory which relate to the similarity of African languages, such as Bambara, to Hebrew as well as similarities of African religious traditions, customs, and rituals to the ancient Jewish ones. Thus, concluding that some of the Israelites left The Exodus journey and settled in Africa, such as the Bambara tribes. The second part of the book describes the author's search for the hidden footsteps of the Ten lost Tribes on Israel. It starts with an historical background of the life in Canaan after the Israelites arrived there from Egypt, and the misfortunate events which led to the expulsion of the Ten Tribes by the Assyrians. It also presents some known historical records of the Japanese people since the time they arrived in their islands including some personal adventurous experiences of the author along the route that they took from Assyria through Asia to Japan. The proof of the theory is greatly related to the author's discoveries of similarities between the Japanese mythological stories, customs, holidays, rituals and their parallel biblical Jewish stories, holidays, custom and traditions. In addition, it presents many linguistic similarities between Hebrew and Japanese including words, writing letters and symbols that support his theory that the Japanese and the ancient Ten Lost Tribes of Israel are strongly related. The book finishes with a dictionary that shows similarities in meaning and pronunciation of many Hebrew, Bambara and Japanese words that support the author's theories that their history is closely related.

Logic is now widely recognized to be one of the foundational disciplines of computing and has found applications in virtually all aspects of the subject, from software engineering and hardware to programming languages and artificial intelligence. There is a growing need for an in-depth survey of the applications in logic in A1 and computer science. The Handbook of Logic in Ariticial Intelligence and Logic Programming and its companion, the Handbook of Logic in Computer Science, have been created in response to this need. We see the creation of the Handbook as a combination of authoritative exposition, comprehensive survey, and fundamental research exploring the underlying themes in the various areas. The intended audience is graduate students and researchers in the areas of A1 and logic, as well as other people interested in the subject. We assume as background some mathematical sophistication. Much of the material will be of interest to logicians and mathematicians. The tables of contents of the volumes were finalized after extensive discussions between handbook authors and second readers. The first volumes present the logical foundations and deduction methodologies extensively used in A1. Volumes 3 and 4 cover reasoning, and Volume 5 details logic programming. The chapters which in many cases are of monograph length and scope, emphasize possible unifying themes. They are written by internationally renowned researchers in the respective areas. The chapters are co-ordinated and their contents have been reviewed in joint meetings.

The economic background to the dismemberment of Czechoslovakia at Munich in 1938 has not received the attention it deserves. This book helps to redress this imbalance by analysing in depth the web of foreign interests - direct foreign investment, foreign long-term loans and the activities of international cartels in Czechoslovakia in the interwar period. After the First World War Central and Southeast Europe became one of the major regions of the world to which capital from France, Great Britain and the United States was exported. Czechoslovakia played a central part in this development: foreign capital sought to invest in Czechoslovak industrial enterprises and banks, to make loans to the state, public institutions and private economic organizations and to influence production, prices and the market through cartel agreements. Dr Teichova discusses in detail the influence of foreign capital and business organizations in mining, the metallurgical industries, engineering, electrical industries, chemical industries and banking in the greater part of the modernized sector of the economy.

This timely book tells the fascinating story of how Zionists colonizers planned and established nearly 700 agricultural settlements, towns, and cities from the 1880s to the present. This extraordinary activity of planners, architects, social scientists, military personnel, politicians, and settlers is inextricably linked to multiple contexts: Jewish and Zionist history, the Arab/Jewish conflict, and the diffusion of European ideas to non-European worlds. S. Ilan Troen demonstrates how professionals and settlers continually innovated plans for both rural and urban frontiers in response to the competing demands of social and political ideologies and the need to achieve productivity, economic independence, and security in a hostile environment. In the 1930s, security became the primary challenge, shaping and even distorting patterns of growth. Not until the 1993 Oslo Accords, with prospects of compromise and accommodation, did planners again imagine Israel as a normal state, developing like other modern societies. Troen concludes that if Palestinian Arabs become reconciled to a Jewish state, Israel will reassign priority to the social and economic development of the country and region.

Yvonne Kapp, best known today for her biography of Eleanor Marx, was a remarkable woman whose life spanned virtually the entire twentieth century. "Time Will Tell" charts her life: 'enfant terrible' in London, the literary editor of "Vogue" in France in the late 1920s, work for anti-fascist refugee committees in 1930s' London, research for the Amalgamated Engineering Union and the British Medical Research Council, then, in her later years, work as a translator and a biographer. Kapp is a gifted writer on the details of family life and a fine recorder of shifting political and cultural patterns. Accounts of the many encounters she had with various important figures--Quentin Bell, Rebecca West, Paul Robeson, John Heartfield, Melanie Klein and Herbert Morrison, to name only a few--are expertly woven into the fascinating story of her own life. This is the autobiography of a woman who took issue with the dominant political movements of her age, with Fascism and with Communism, while at the same time reflecting on the changing cultural and political climate in Britain during her lifetime.

In this trenchant challenge to social engineering, Paul Gottfried analyzes a patricide: the slaying of nineteenth-century liberalism by the managerial state. Many people, of course, realize that liberalism no longer connotes distributed powers and bourgeois moral standards, the need to protect civil society from an encroaching state, or the virtues of vigorous self-government. Many also know that today's "liberals" have far different goals from those of their predecessors, aiming as they do largely to combat prejudice, to provide social services and welfare benefits, and to defend expressive and "lifestyle" freedoms. Paul Gottfried does more than analyze these historical facts, however. He builds on them to show why it matters that the managerial state has replaced traditional liberalism: the new regimes of social engineers, he maintains, are elitists, and their rule is consensual only in the sense that it is unopposed by any widespread organized opposition. Throughout the western world, increasingly uprooted populations unthinkingly accept centralized controls in exchange for a variety of entitlements. In their frightening passivity, Gottfried locates the quandary for traditionalist and populist adversaries of the welfare state. How can opponents of administrative elites show the public that those who provide, however ineptly, for their material needs are the enemies of democratic self-rule and of independent decision making in family life? If we do not wake up, Gottfried warns, the political debate may soon be over, despite sporadic and ideologically confused populist rumblings in both Europe and the United States.
