Jephan de Villiers’ book is an invitation to break away from the alienating burdens of everyday life and immerse ourselves in an imaginary civilisation. Here, we set out with the artist on a journey to encounter a lost world, where nature and culture were once closely entwined, where humanity lived in harmony with the elements. Trees and water are of central importance throughout the artist's work. Whether as a reminder of the origins of life or as testimonies of ancestral beliefs and practices, nothing has been invented in this singular world of sculptures. Everything in his work has been composed and transferred from a forgotten world. His creations are made from materials derived from natural objects that have fallen to the ground: splinters of wood, bark, water chestnuts, rays' eggs, mysterious sea balls washed up by the ocean and fragments of horseshoe crab shells. For the artist, the time he devotes to his work means being alone, in the strictest sense of the word. It is time spent scouring the ground, in search of materials gathered "on the edge of the world". His work of one of memory, a tribute to all those on the look‐out, watching over our forgotten world. Text in English and French.

From the Big Bang to Hiroshima, the incredible story of the most disastrous weapon ever invented On August 6, 1945, at 8:15 in the morning, an explosive charge of more than 15 kilotons fell on the city of Hiroshima. Tens of thousands of people were pulverized, and everything within four square miles was instantly destroyed. A deluge of flames and ash had just caused Japan’s greatest trauma and changed the course of modern warfare and life on Earth forever. The world was horrified by the existence of the bomb—the first weapon of mass destruction. But how could such an appalling tool be invented? To answer this question, Alcante, Laurent-Frédéric Bollée, and Denis Rodier return to the origins of its main component, uranium, and shed light on the scientific discoveries around this element and its uses both civilian and military. Sifting through the history, from Katanga to Japan, through Germany, Norway, the USSR, and New Mexico, The Bomb is a succession of incredible but true stories. Alcante, Bollée, and Rodier have created an exhaustive and definitive work of nonfiction that details the stories of the unsung players as well as the remarkable men and women who are at the crux of its history and the events that followed.

This volume has its origins in the Barcelona Conference in Group Theory (July 2005) and the conference "Asymptotic and Probabilistic Methods in Geometric Group Theory" held in Geneva (June 2005). Twelve peer-reviewed research articles written by experts in the field present the most recent results in abstract and geometric group theory. In particular there are two articles by A. Juhász.

Robust optimization is still a relatively new approach to optimization problems affected by uncertainty, but it has already proved so useful in real applications that it is difficult to tackle such problems today without considering this powerful methodology. Written by the principal developers of robust optimization, and describing the main achievements of a decade of research, this is the first book to provide a comprehensive and up-to-date account of the subject. Robust optimization is designed to meet some major challenges associated with uncertainty-affected optimization problems: to operate under lack of full information on the nature of uncertainty; to model the problem in a form that can be solved efficiently; and to provide guarantees about the performance of the solution. The book starts with a relatively simple treatment of uncertain linear programming, proceeding with a deep analysis of the interconnections between the construction of appropriate uncertainty sets and the classical chance constraints (probabilistic) approach. It then develops the robust optimization theory for uncertain conic quadratic and semidefinite optimization problems and dynamic (multistage) problems. The theory is supported by numerous examples and computational illustrations. An essential book for anyone working on optimization and decision making under uncertainty, Robust Optimization also makes an ideal graduate textbook on the subject.

This book offers a practical answer for the non-mathematician to all the questions any businessman always wanted to ask about risk quantification, and never dare to ask. Enterprise-wide risk management (ERM) is a key issue for board of directors worldwide. Its proper implementation ensures transparent governance with all stakeholders’ interests integrated into the strategic equation. Furthermore, Risk quantification is the cornerstone of effective risk management,at the strategic and tactical level, covering finance as well as ethics considerations. Both downside and upside risks (threats & opportunities) must be assessed to select the most efficient risk control measures and to set up efficient risk financing mechanisms. Only thus will an optimum return on capital and a reliable protection against bankruptcy be ensured, i.e. long term sustainable development. Within the ERM framework, each individual operational entity is called upon to control its own risks, within the guidelines set up by the board of directors, whereas the risk financing strategy is developed and implemented at the corporate level to optimise the balance between threats and opportunities, systematic and non systematic risks. This book is designed to equip each board member, each executives and each field manager, with the tool box enabling them to quantify the risks within his/her jurisdiction to all the extend possible and thus make sound, rational and justifiable decisions, while recognising the limits of the exercise. Beyond traditional probability analysis, used since the 18th Century by the insurance community, it offers insight into new developments like Bayesian expert networks, Monte-Carlo simulation, etc. with practical illustrations on how to implement them within the three steps of risk management, diagnostic, treatment and audit. With a foreword by Catherine Veret and an introduction by Kevin Knight.
