Theory and Practice of Finite Elements

Theory and Practice of Finite Elements

Alexandre Ern; Jean-Luc Guermond

Springer-Verlag New York Inc.
2004
sidottu
The origins of the finite element method can be traced back to the 1950s when engineers started to solve numerically structural mechanics problems in aeronautics. Since then, the field of applications has widened steadily and nowadays encompasses nonlinear solid mechanics, fluid/structure interactions, flows in industrial or geophysical settings, multicomponent reactive turbulent flows, mass transfer in porous media, viscoelastic flows in medical sciences, electromagnetism, wave scattering problems, and option pricing (to cite a few examples). Numerous commercial and academic codes based on the finite element method have been developed over the years. The method has been so successful to solve Partial Differential Equations (PDEs) that the term "Finite Element Method" nowadays refers not only to the mere interpolation technique it is, but also to a fuzzy set of PDEs and approximation techniques. The efficiency of the finite element method relies on two distinct ingredi­ ents: the interpolation capability of finite elements (referred to as the approx­ imability property in this book) and the ability of the user to approximate his model (mostly a set of PDEs) in a proper mathematical setting (thus guar­ anteeing continuity, stability, and consistency properties). Experience shows that failure to produce an approximate solution with an acceptable accuracy is almost invariably linked to departure from the mathematical foundations. Typical examples include non-physical oscillations, spurious modes, and lock­ ing effects. In most cases, a remedy can be designed if the mathematical framework is properly set up.

My thanks also go to Vladimir Zaiats for his highly competent translation of the French original into English and to John Kimmel for being a very supportive and patient editor. Alexandre Tsybakov Paris, June 2008 Preface to the French Edition The tradition of considering the problem of statistical estimation as that of estimation of a ?nite number of parameters goes back to Fisher. However, parametric models provide only an approximation, often imprecise, of the - derlying statistical structure. Statistical models that explain the data in a more consistent way are often more complex: Unknown elements in these models are, in general, some functions having certain properties of smoo- ness.

Vorticity and Turbulence

Vorticity and Turbulence

Alexandre J. Chorin

Springer-Verlag New York Inc.
1994
sidottu
This book provides an introduction to the theory of turbulence in fluids based on the representation of the flow by means of its vorticity field. It has long been understood that, at least in the case of incompressible flow, the vorticity representation is natural and physically transparent, yet the development of a theory of turbulence in this representation has been slow. The pioneering work of Onsager and of Joyce and Montgomery on the statistical mechanics of two-dimensional vortex systems has only recently been put on a firm mathematical footing, and the three-dimensional theory remains in parts speculative and even controversial. The first three chapters of the book contain a reasonably standard intro­ duction to homogeneous turbulence (the simplest case); a quick review of fluid mechanics is followed by a summary of the appropriate Fourier theory (more detailed than is customary in fluid mechanics) and by a summary of Kolmogorov's theory of the inertial range, slanted so as to dovetail with later vortex-based arguments. The possibility that the inertial spectrum is an equilibrium spectrum is raised.

A Mathematical Introduction to Fluid Mechanics

A Mathematical Introduction to Fluid Mechanics

Alexandre J. Chorin; Jerrold E. Marsden

Springer-Verlag New York Inc.
1993
sidottu
Mathematics is playing an ever more important role in the physical and biological sciences, provoking a blurring of boundaries between scientific disciplines and a resurgence of interest in the modern as weil as the clas­ sical techniques of applied mathematics. This renewal of interest, bothin research and teaching, has led to the establishment of the series: Texts in Applied Mathematics (TAM). The development of new courses is a natural consequence of a high Ievel of excitement on the research frontier as newer techniques, such as numerical and symbolic computer systems, dynamical systems, and chaos, mix with and reinforce the traditional methods of applied mathematics. Thus, the purpose of this textbook series is to meet the current and future needs of these advances and encourage the teaching of new courses. TAM will publish textbooks suitable for use in advanced undergraduate and beginning graduate courses, and will complement the Applied Mathematical Seiences (AMS) series, whichwill focus on advanced textbooks and research Ievel monographs. Preface This book is based on a one-term coursein fluid mechanics originally taught in the Department of Mathematics of the U niversity of California, Berkeley, during the spring of 1978. The goal of the course was not to provide an exhaustive account of fluid mechanics, nor to assess the engineering value of various approximation procedures.

The Astronomical Revolution

The Astronomical Revolution

Alexandre Koyre

Routledge
2008
sidottu
Originally published in English in 1973. This volume traces the development of the revolution which so drastically altered man’s view of the universe in the sixteenth and seventeenth centuries. The "astronomical revolution" was accomplished in three stages, each linked with the work of one man. With Copernicus, the sun became the centre of the universe. With Kepler, celestial dynamics replaced the kinematics of circles and spheres used by Copernicus. With Borelli the unification of celestial and terrestrial physics was completed by abandonment of the circle in favour the straight line to infinity.

Tolstoy's Political Thought

Tolstoy's Political Thought

Alexandre Christoyannopoulos

Routledge
2019
sidottu
Leo Tolstoy (1828–1910), besides writing famous novels such as War and Peace, also wrote on political issues, especially later in his life, putting forward a political philosophy which might be termed 'Christian anarchism'. This book provides a comprehensive overview of Tolstoy’s political thought. It outlines in a systematic way Tolstoy’s thought, which was originally articulated unsystematically in diverse, often informal writing, such as pamphlets, letters, and speeches, as well as books, and in his novels, where Tolstoy’s thinking is put forward implicitly through the novels’ characters. The book sets out the basic themes of Tolstoy’s political thought: his acceptance of the teachings of Jesus, his criticism of the way in which Jesus’ teachings have been relayed by the church through traditional creeds and dogma, his passionate rejection of political violence by both the state and those working for reform, his plea for a nonviolent response to violence and injustice, and his call for society to forego its institutional shackles and enact a community of peace, love, and justice. The book also includes background information on the Russia of Tolstoy’s time, including the religious context, and a discussion of how Tolstoy’s political thought has been received by his admirers, who included Gandhi, and his critics.

Human Resource Development in the Russian Federation

Human Resource Development in the Russian Federation

Alexandre Ardichvili; Elena Zavyalova

Routledge
2015
sidottu
Unlike Brazil, India, or China, prior to the beginning of market-oriented reforms in early 1990s, Russia maintained a high level of human capital and possessed a highly developed system of vocational education, continuous education, and management development institutions sponsored by the government. However, after the beginning of the market reforms many state-sponsored programs were disbanded and individual enterprises and newly emerging private educational institutions found themselves in a position of having to provide training and professional development services for future and current employees. Both government-level policies in support of HRD and enterprise-level HRD systems have emerged fairly recently in the Russian Federation, and are still in a stage of change and development. This book provides an in-depth analysis of the current state of HRD in the Russian Federation. It covers country-level policies, organizational-level programs and strategies, and individual-level educational and training efforts. While the study is focused on Russia, its conclusions will be of value to scholars, students, and practitioners examining similar issues surrounding the emergence and development of HRD systems in emerging countries. Furthermore, the authors’ framework for analyzing HRD on multiple levels and across various parts of the adult and vocational education and development systems offers a unique and important contribution to the theoretical debate on comparative educational systems outside the HRD and HRM communities.

Black Tulip

Black Tulip

Alexandre Dumas

Dover Publications Inc.
2017
nidottu
A prize of 100,000 guilders awaits the gardener who can produce a black tulip, a rich reward that incites a bitter competition in 17th-century Holland. Cornelius von Baerle, a gifted and passionate florist, has dedicated himself to cultivating the elusive flower. But a ruthless rival, capitalizing on accusations that led to the assassination of Cornelius's godfather, falsely accuses the young horticulturist of treason. Sentenced to life imprisonment, Cornelius conspires with his jailer's daughter to grow the black tulip in secret.Alexandre Dumas sets his captivating tale in the 1670s, a generation after Holland was gripped by the economic madness of Tulip mania and shortly after the mob lynching of a pair of Dutch statesmen. His fictional treatment of these historic events forms a timeless political allegory in which the rare flower represents the triumph of justice, tolerance, and true love over greed, jealousy, and obsession.
