The contributions in this volume represent a selection of the papers presented at the Conference on Extreme Value Theory and Applications held in Gaithersburg, Maryland, USA in 1993. Recent rapid advancement in the theory of extremes, in the statistical inference of extreme-related problems and the ever-increasing acceptance of the theory in applications brought together experts in the fields of model-building statistics, engineering and business, whose presentations on these matters are published in this volume. A variety of engineering applications are covered: strength due to fatigue failure; bundle strength of fibre; longest living humans; concomitants of extremes, such as characteristics of offspring of the present generation; long-run asset risk; reinsurance; high winds; and other applications. The theoreticians address model-building and the newest results of statistical inference, including Bayesian methods. This volume should be of interest to statisticians, mathematicians, engineers and business professionals with a basic knowledge of probability and statistics.

It appears that we live in an age of disasters: the mighty Missis­ sippi and Missouri flood millions of acres, earthquakes hit Tokyo and California, airplanes crash due to mechanical failure and the seemingly ever increasing wind speeds make the storms more and more frightening. While all these may seem to be unexpected phenomena to the man on the street, they are actually happening according to well defined rules of science known as extreme value theory. We know that records must be broken in the future, so if a flood design is based on the worst case of the past then we are not really prepared against floods. Materials will fail due to fatigue, so if the body of an aircraft looks fine to the naked eye, it might still suddenly fail if the aircraft has been in operation over an extended period of time. Our theory has by now penetrated the so­ cial sciences, the medical profession, economics and even astronomy. We believe that our field has come of age. In or~er to fully utilize the great progress in the theory of extremes and its ever increasing acceptance in practice, an international conference was organized in which equal weight was given to theory and practice. This book is Volume I of the Proceedings of this conference. In selecting the papers for Volume lour guide was to have authoritative works with a large variety of coverage of both theory and practice.

This is the inside story of an Army Ranger, surrounded and outnumbered, fighting a desperate action on the ground during the Black Hawk Down raid in Somalia in 1993. ??In 1993 Lieutenant James Lechner, a member of the 3rd Ranger Battalion, was selected for a top secret special operations task force being sent to Mogadishu, Somalia, to capture the insurgent leader Mohamed Farah Aideed. In early October, after conducting a number of raids in the city, the Task Force is called upon to conduct a daring daylight mission into the heart of Aideed''s territory. During the raid, one of the Black Hawk helicopters is shot down and Lechner and his comrades are soon caught up in the fiercest combat involving US forces since the Vietnam War. Deep in the enemy''s stronghold, the small group of Rangers and special operators now find themselves fighting not only to rescue the downed helicopter''s crewmen, but also to save their own lives.??This first-hand account tells the story of how these elite warriors were able to stand together and prevail against incredible odds. It gives the reader the perspective of an Army Ranger fighting on the ground, combined with professional military analysis, in a groundbreaking book that tells the complete story with never-before-revealed details. Published in association with the AUSA Book Program, offering quality books about US Army heritage, military theory and policy, and security in the modern world.
