The main idea of statistical convergence is to demand convergence only for a majority of elements of a sequence. This method of convergence has been investigated in many fundamental areas of mathematics such as: measure theory, approximation theory, fuzzy logic theory, summability theory, and so on. In this monograph we consider this concept in approximating a function by linear operators, especially when the classical limit fails. The results of this book not only cover the classical and statistical approximation theory, but also are applied in the fuzzy logic via the fuzzy-valued operators. The authors in particular treat the important Korovkin approximation theory of positive linear operators in statistical and fuzzy sense. They also present various statistical approximation theorems for some specific real and complex-valued linear operators that are not positive. This is the first monograph in Statistical Approximation Theory and Fuzziness. The chapters are self-contained and several advanced courses can be taught. The research findings will be useful in various applications including applied and computational mathematics, stochastics, engineering, artificial intelligence, vision and machine learning. This monograph is directed to graduate students, researchers, practitioners and professors of all disciplines.

Physics and Applications of Secondary Electron Emission provides a survey of the physics and applications of secondary electron emission. It is part of a series of monographs that aim to report on research carried out in electronics and applied physics. The monographs are written by specialists in their own subjects. Wherever it is practical the monographs will be kept short in length to enable all those interested in electronics to find the essentials necessary for their work in a condensed and concentrated form. The book begins with a discussion of secondary electrons. Separate chapters cover methods for measuring secondary electron emission; numerical results on the secondary electron emission yield of both metals and metal compounds; the influence of externally adsorbed foreign atoms and ions on secondary electron emission; and the mechanism of secondary electron emission. The final three chapters deal with the application side. These include the applications of electron multiplication; the elimination of disturbing effects due to secondary electrons; and ""storage"" devices in which information on electrical charges is written on an insulating surface, often by making use of secondary electron emission.

An international community of specialists reinvented the propeller during the Aeronautical Revolution, a vibrant period of innovation in North America and Europe from World War I to the end of World War II. They experienced both success and failure as they created competing designs that enabled increasingly sophisticated and 'modern' commercial and military aircraft to climb quicker and cruise faster using less power. Reinventing the Propeller nimbly moves from the minds of these inventors to their drawing boards, workshops, research and development facilities, and factories, and then shows us how their work performed in the air, both commercially and militarily. Reinventing the Propeller documents this story of a forgotten technology to reveal new perspectives on engineering, research and development, design, and the multi-layered social, cultural, financial, commercial, industrial, and military infrastructure of aviation.

"Vietnam 1946 is a masterful narrative of the immediate origins of the first Vietnam War. It is, by turns, vivid and shocking; it is always immensely revealing. Tønnesson brings forensic clarity to crucial events about which, even now, some sixty years later, fundamental misapprehensions exist. An outstanding work of scholarship of major international importance."—Martin Thomas, author of Empires of Intelligence "Tønnesson captures brilliantly the 1946 confrontation between two republics: France determined to redeem itself from Axis humiliation by regaining Indochina; Vietnam equally determined to retake independence after eighty years of colonial servitude. Tønnesson also demonstrates, however, that some leaders on each side really wanted a peaceful, mutually beneficial outcome. Descent into full-scale war was not inevitable. This is a carefully researched, clearly written analysis of a vital moment in the 20th century history of both countries. It is also a meditation on the elusive boundary between free will and determinism in human affairs."—David Marr, author of Vietnamese Tradition on Trial, 1920-1945 “Stein Tønnesson's Vietnam 1946 answers the fundamental question about the first of Vietnam's 20th century wars, the one fought against the French: how did it happen? He has written a meticulously researched account which restores their contingency to the events. The first Indochina war, like those that succeeded it, was not inevitable and Tønnesson explains why and how it happened anyway.”—Marilyn Young, author of The Vietnam Wars 1945-1990
