Book Description
In recent years cuneiform studies have witnessed a growing interest in issues variously related to the broadly defined field of palaeography. This led to the development of new methodologies and technologies as well as to the establishment of several projects devoted to the palaeographic analysis of cuneiform corpora from Mesopotamia, Syria, Anatolia and New Kingdom Egypt, spanning from the 3rd to the 1st millennium BC. This volume collects papers from scholars who had been working on topics such as writing space, wedge order, quantitative analysis, text reconstruction, sign identification and palaeographic dating, providing an updated overview on the present state of the art.

Book Description
"The Babylonian Gilgamesh epic is the oldest long poem in the world, with a history going back four thousand years. It tells the fascinating and moving story of Gilgamesh's heroic deeds and lonely quest for immortality. This book collects for the first time all the known sources in the original cuneiform, including many fragments never published before. The author's personal study of every available fragment has produced a definitive edition and translation, complete with comprehensive introductory chapters that place the poem and its hero in context."--Publisher's description.

Book Description
Information and communication technology (ICT) has become a generic and indispensable tool for addressing and solving problems in such diverse areas as management, social and health services, transportation, security and education. As the cost of equipment drops dramatically, it also becomes widely accessible in the developing countries. However, problems of high costs for adequate training of personnel, access to state-to-the-art software and the consultancies needed to facilitate access to ICT can constitute highly dissuasive factors in the dissemination of ICT in developing countries.This volume describes a series of successful initiatives for the insertion of ICT in developing economies. It also identifies significant problems that are likely to be encountered, and suggests useful solutions to these problems. It therefore serves as a useful tool for example applications, and for the successful assimilation of these technologies in developing societies and countries./a

Book Description
An introduction to computational complexity theory, its connections and interactions with mathematics, and its central role in the natural and social sciences, technology, and philosophy Mathematics and Computation provides a broad, conceptual overview of computational complexity theory—the mathematical study of efficient computation. With important practical applications to computer science and industry, computational complexity theory has evolved into a highly interdisciplinary field, with strong links to most mathematical areas and to a growing number of scientific endeavors. Avi Wigderson takes a sweeping survey of complexity theory, emphasizing the field’s insights and challenges. He explains the ideas and motivations leading to key models, notions, and results. In particular, he looks at algorithms and complexity, computations and proofs, randomness and interaction, quantum and arithmetic computation, and cryptography and learning, all as parts of a cohesive whole with numerous cross-influences. Wigderson illustrates the immense breadth of the field, its beauty and richness, and its diverse and growing interactions with other areas of mathematics. He ends with a comprehensive look at the theory of computation, its methodology and aspirations, and the unique and fundamental ways in which it has shaped and will further shape science, technology, and society. For further reading, an extensive bibliography is provided for all topics covered. Mathematics and Computation is useful for undergraduate and graduate students in mathematics, computer science, and related fields, as well as researchers and teachers in these fields. Many parts require little background, and serve as an invitation to newcomers seeking an introduction to the theory of computation. Comprehensive coverage of computational complexity theory, and beyond High-level, intuitive exposition, which brings conceptual clarity to this central and dynamic scientific discipline Historical accounts of the evolution and motivations of central concepts and models A broad view of the theory of computation's influence on science, technology, and society Extensive bibliography

Book Description
In 1980 the Internal Emitters Committee of EULEP organised a symposium in Rotterdam on Bone and Bone Seeking Radionu cI ides: Their Physiology, Dosimetry and Effects. The speakers for this meeting, mostly from EULEP associ ated laboratories, were chosen to review this field of scientific research mostly for the benefit of interested scientists who were not actively researching with bone seeking radionuclides. This meeting was a success and its proceedings were subsequently published in the form of a book by the Commission of the European Communities, reflecting the great importance that both EULEP and the Radiologi cal Protection Programme of the Commission of the European Communities attaches to the study of radionuclides that deposit in bone. The Metals in Bone symposium in Angers was intended to serve a different function from that of the meeting held in Rotterdam in that, while these proceed ings will certainly be of interest to non-involved scientists, the meeting was intended to be of most benefit to those actively researching the metabolism and effects of bone-seeking metals. Moreover, in an attempt to increase the value of its discussions and the number of interested and participating scientists, the remit of the meeting was broader and set to include papers on stable as well as radioactive metals.

Book Description
This practical new book offers the distributed-computing fundamental knowledge for individuals to connect with one another in a more secure and efficient way than with traditional blockchains. These new forms of secure, scalable blockchains promise to replace centralized institutions to connect individuals without the risks of user manipulations or data extortions. The techniques taught herein consist of enhancing blockchain security and making blockchain scalable by relying on the observation that no blockchain can exist without solving the consensus problem. First, the state-of-the-art of consensus protocols are analyzed, hence motivating the need for a new family of consensus protocols offering strong (deterministic) guarantees. Second, a didactic series of classic blockchain vulnerabilities is presented to illustrate the importance of novel designs better suited for the adversarial environment of open networks. These cutting-edge solutions are illustrated through the Redbelly blockchain design, which solves a different problem from the classic Byzantine consensus problem of 1982 and which delivers—in the modern blockchain context—high performance at large scale. Topics and features: Covers the combination of security and distributed computing to devise the new generation of blockchains Shows how blockchain has shed new light on decades of research in distributed systems Provides instruction on the security needed by the industry to use blockchains in production Explains didactically the necessary ingredients to make blockchain efficient at large scale Helps fill the gap of knowledge in the highly demanded blockchain sector This unique volume contains the building blocks to design secure and scalable blockchains. As such, it is dedicated to developers, application designers, and computer scientists and requires only a minimal undergraduate level in mathematics and computer science. Vincent Gramoli is an Australian Research Council Future Fellow at the University of Sydney and the Chief Technology Officer of Redbelly Network. He teaches the Blockchain Scalability course on Coursera.
