Aluminum–Lithium Alloys: Process Metallurgy, Physical Metallurgy, and Welding provides theoretical foundations of the technological processes for melting, casting, forming, heat treatment, and welding of Al–Li alloys. It contains a critical survey of the research in the field and presents data on commercial Al–Li alloys, their phase composition, microstructure, and heat treatment of the ingots, sheets, forgings, and welds of Al–Li alloys. It details oxidation kinetics, protective alloying, hydrogen in Al–Li alloys, and crack susceptibility. It also discusses grain structure and solidification, as well as structural and mechanical properties. The book is illustrated with examples of Al–Li alloy applications in aircraft structures. Based on the vast experience of the coauthors, the book presents recommendations on solving practical problems involved with melting and casting ingots, welding of Al–Li alloys, and producing massive stampings for welded products. Provides comprehensive coverage of Al–Li alloys, not available in any single source. Presents research that is at the basis of the production technology for of ingots and products made of Al–Li alloys. Combines basic science with applied research, including upscaling and industrial implementation. Covers welding of Al–Li alloys in detail. Discusses gas and alkali-earth impurities in Al–Li alloys. Describes technological recommendations on casting and deformation of Al–Li alloys.
This book concentrates on the branching solutions of nonlinear operator equations and the theory of degenerate operator-differential equations especially applicable to algorithmic analysis and nonlinear PDE's in mechanics and mathematical physics. The authors expound the recent result on the generalized eigen-value problem, the perturbation method, Schmidt's pseudo-inversion for regularization of linear and nonlinear problems in the branching theory and group methods in bifurcation theory. The book covers regular iterative methods in a neighborhood of branch points and the theory of differential-operator equations with a non-invertible operator in the main expression is constructed. Various recent results on theorems of existence are given including asymptotic, approximate and group methods.
This book discusses the effect of the excitation of rotational, vibrational, and electronic degrees of freedom on the basic electrical properties of molecules and, as a consequence, on molecular optical and transport properties together with reactivity. It additionally summarizes the theory and practice of calculating state-specific electric and optical properties based on ab initio quantum chemical calculations. The book offers a clear, up-to-date review and is primarily intended for actively working researchers, graduate students, and advanced undergraduates who are interested in the electric and related properties of the electronically, rotationally, and vibrationally excited molecules.
Impulsive Control in Continuous and Discrete-Continuous Systems is an up-to-date introduction to the theory of impulsive control in nonlinear systems. This is a new branch of the Optimal Control Theory, which is tightly connected to the Theory of Hybrid Systems. The text introduces the reader to the interesting area of optimal control problems with discontinuous solutions, discussing the application of a new and effective method of discontinuous time-transformation. With a large number of examples, illustrations, and applied problems arising in the area of observation control, this book is excellent as a textbook or reference for a senior or graduate-level course on the subject, as well as a reference for researchers in related fields.
The Russian edition of this book appeared in 1976 on the hundred-and-fiftieth anniversary of the historic day of February 23, 1826, when LobaeevskiI delivered his famous lecture on his discovery of non-Euclidean geometry. The importance of the discovery of non-Euclidean geometry goes far beyond the limits of geometry itself. It is safe to say that it was a turning point in the history of all mathematics. The scientific revolution of the seventeenth century marked the transition from "mathematics of constant magnitudes" to "mathematics of variable magnitudes. " During the seventies of the last century there occurred another scientific revolution. By that time mathematicians had become familiar with the ideas of non-Euclidean geometry and the algebraic ideas of group and field (all of which appeared at about the same time), and the (later) ideas of set theory. This gave rise to many geometries in addition to the Euclidean geometry previously regarded as the only conceivable possibility, to the arithmetics and algebras of many groups and fields in addition to the arith metic and algebra of real and complex numbers, and, finally, to new mathe matical systems, i. e. , sets furnished with various structures having no classical analogues. Thus in the 1870's there began a new mathematical era usually called, until the middle of the twentieth century, the era of modern mathe matics.

In 1939, a ten-year-old Igor Golomstock accompanied his mother, a medical doctor, to the vast network of labour camps in the Russian Far East. While she tended patients, he was minded by assorted 'trusty' prisoners – hardened criminals – and returned to Moscow an almost feral adolescent, fluent in obscene prison jargon but intellectually ignorant. Despite this dubious start he became a leading art historian and co-author (with his close friend Andrey Sinyavsky) of the first, deeply controversial, monograph on Picasso published in the Soviet Union. His writings on his 43 years in the Soviet Union offer a rare insight into life as a quietly subversive art historian and the post-Stalin dissident community. In vivid prose Golomstock shows the difficulties of publishing, curating and talking about Western art in Soviet Russia and, with self-deprecating humour, the absurd tragicomedy of life for the Moscow intelligentsia during Khruschev's thaw and Brezhnev's stagnation. He also offers a unique personal perspective on the 1966 trial of Sinyavsky and Yuri Daniel, widely considered the end of Khruschev's liberalism and the spark that ignited the Soviet dissident movement. In 1972 he was given 'permission' to leave the Soviet Union, but only after paying a 'ransom' of more than 25 years' salary, nominally intended to reimburse the state for his education. A remarkable collection of artists, scholars and intellectuals in Russia and the West, including Roland Penrose, came together to help him pay this astronomical sum. His memoirs of life once in the UK offer an insider's view of the BBC Russian Service and a penetrating analysis of the notorious feud between Sinyavsky and Aleksandr Solzhenitsyn. Nominated for the Russian Booker Prize on its publication in Russian in 2014, The Ransomed Dissident opens a window onto the life of a remarkable man: a dissident of uncompromising moral integrity and with an outstanding gift for friendship.
