This book describes a family of algorithms for studying the global structure of systems. By a finite covering of the phase space we construct a directed graph with vertices corresponding to cells of the covering and edges corresponding to admissible transitions. The method is used, among other things, to locate the periodic orbits and the chain recurrent set, to construct the attractors and their basins, to estimate the entropy, and more.
Published in 1950: Here is the first comprehensive study of Korea since its liberation and division. Written by an outstanding American authority with long personal knowledge of the country, it provides an analysis of the American and Russian military occupations, the efforts of the United Nations to deal with the problem of Unification of the country, the political and economic policies followed in the northern and southern regimes, and an appraisal of the U.S. program of economic and military aid to South Korea.
Global attention in scientific, industrial, and governmental commumtles to traces of toxic chemicals in foodstuffs and in both abiotic and biotic environ ments has justified the present triumvirate of specialized publications III this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are Illtegrated and scheduled to pro vide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental con tamination and toxicology. Until now there has been no journal or other publica tion series reserved exclusively for the diversified literature on "toxic" chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wildlife, and ourselves. Around the world immense efforts and many talents have been mobilized to techmcal and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authoritative publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancil lary legislation.
This book focuses on the Soviet aces who scored all, or most of their victories in the Yak, drawing information from official unit histories and memoirs of the Soviet pilots themselves. The Yak-1 entered Soviet service in 1941, one of three modern types of aircraft accepted for production just prior to the German invasion of the USSR. Despite initial shortcomings, it soon proved to be the thoroughbred of the Soviet Airforce. Indeed, it remained in production until the end of the war, modernized but fundamentally recognizable. By VE-day about 33,100 Yakovlev fighters had been built. Virtually all Soviet fighter regiments flew at least one variety of Yak for a time, including those which gained their fame identified with other aircraft, and consequently many pilots known as Airacobra or Lavochkin aces also scored victories with the Yak. Many other famous aces were exclusively 'Yak patriots', including the French Normandie pilots.
A conveniently sized atlas for home or office, this edition contains up-to-date, comprehensive, and authoritative coverage of exceptional maps of the world.
