Adaptation in dynamical systems par Tyukin, Ivan. Publication : Cambridge | New York Cambridge University Press 2011 . xvii, 410 pages , "In the context of this book, adaptation is taken to mean a feature of a system aimed at achieving the best possible performance, when mathematical models of the environment and the system itself are not fully available. This has applications ranging from theories of visual perception and the processing of information, to the more technical problems of friction compensation and adaptive classification of signals in fixed-weight recurrent neural networks. Largely devoted to the problems of adaptive regulation, tracking and identification, this book presents a unifying system-theoretic view on the problem of adaptation in dynamical systems. Special attention is given to systems with nonlinearly parameterized models of uncertainty. Concepts, methods and algorithms given in the text can be successfully employed in wider areas of science and technology. The detailed examples and background information make this book suitable for a wide range of researchers and graduates in cybernetics, mathematical modelling and neuroscience"-- 26 cm Date : 2011 Disponibilité : Exemplaires disponibles: La bibliothèque des Sciences Exactes et Naturelles (1),

Damped wave transport and relaxation / par Sharma,, Kal Renganathan. Publication : [S.l.] : Elsevier Science, 2005 . 462 p. ; , Transient problems in transport phenomena have a variety of applications, ranging from drug delivery systems in chemotherapy in bioengineering to heat transfer to surfaces in fluidized bed combustion (FBC) boilers in mechanical engineering. However, the attention given to transient problems is disproportionate with its occurrence in the industry. Damped Wave Transport and Relaxation looks at transient problems in heat, mass and momentum transfer: including non-Fourier effects of conduction and relaxation; non-Fick effects of mass diffusion and relaxation; and non-Newtonian effects of viscous momentum transfer and relaxation. The author also reviews applications to current problems of interest and uses worked examples and illustrations to describe the manifestations of using generalized transport equations. This book is intended for graduate students in transport phenomena and is an ideal reference source for industrial engineers. * Provides a connection with molecular phenomena * Separate sections are devoted to heat, mass and momentum transfer * Includes exercises and examples of applications. 25 cm.

Engineering turbulence modelling and experiments 6 : ercoftac international symposium on engineering turbulence and measurements - etmm6.   Publication : [S.l.] : Elsevier Science, 2005 . 1012 p. ; , Proceedings of the world renowned ERCOFTAC (International Symposium on Engineering Turbulence Modelling and Measurements). The proceedings include papers dealing with the following areas of turbulence: Âɛ Eddy-viscosity and second-order RANS models Âɛ Direct and large-eddy simulations and deductions for conventional modelling Âɛ Measurement and visualization techniques, experimental studies Âɛ Turbulence control Âɛ Transition and effects of curvature, rotation and buoyancy on turbulence Âɛ Aero-acoustics Âɛ Heat and mass transfer and chemically reacting flows Âɛ Compressible flows, shock phenomena Âɛ Two-phase flows Âɛ Applications in aerospace engineering, turbomachinery and reciprocating engines, industrial aerodynamics and wind engineering, and selected chemical engineering problems Turbulence remains one of the key issues in tackling engineering flow problems. These problems are solved more and more by CFD analysis, the reliability of which depends strongly on the performance of the turbulence models employed. Successful simulation of turbulence requires the understanding of the complex physical phenomena involved and suitable models for describing the turbulent momentum, heat and mass transfer. For the understanding of turbulence phenomena, experiments are indispensable, but they are equally important for providing data for the development and testing of turbulence models and hence for CFD software validation. As in other fields of Science, in the rapidly developing discipline of turbulence, swift progress can be achieved only by keeping up to date with recent advances all over the world and by exchanging ideas with colleagues active in related fields. 25 cm.

Finite element analysis of acoustic scattering par Ihlenburg, Frank. Publication : NEW YORK Springer 1998 . 238 p. , A cognitive journey towards the reliable simulation of scattering problems using finite element methods, with the pre-asymptotic analysis of Galerkin FEM for the Helmholtz equation with moderate and large wave number forming the core of this book. Starting from the basic physical assumptions, the author methodically develops both the strong and weak forms of the governing equations, while the main chapter on finite element analysis is preceded by a systematic treatment of Galerkin methods for indefinite sesquilinear forms. In the final chapter, three dimensional computational simulations are presented and compared with experimental data. The author also includes broad reference material on numerical methods for the Helmholtz equation in unbounded domains, including Dirichlet-to-Neumann methods, absorbing boundary conditions, infinite elements and the perfectly matched layer. A self-contained and easily readable work. 25 cm. Date : 1998 Disponibilité : Exemplaires disponibles: La bibliothèque des Sciences Exactes et Naturelles (1),

Modeling fluctuations in scattered waves par Jakeman,, E. Publication : [S.l.] Taylor & Francis 2006 . 336 p. , Fluctuations in scattered waves limit the performance of imaging and remote sensing systems that operate on all wavelengths of the electromagnetic spectrum. To better understand these fluctuations, Modeling Fluctuations in Scattered Waves provides a practical guide to the phenomenology, mathematics, and simulation of non-Gaussian noise models and discusses how they can be used to characterize the statistics of scattered waves. Through their discussion of mathematical models, the authors demonstrate the development of new sensing techniques as well as offer intelligent choices that can be made for system analysis. Using experimental results and numerical simulation, the book illustrates the properties and applications of these models. The first two chapters introduce statistical tools and the properties of Gaussian noise, including results on phase statistics. The following chapters describe Gaussian processes and the random walk model, address multiple scattering effects and propagation through an extended medium, and explore scattering vector waves and polarization fluctuations. Finally, the authors examine the generation of random processes and the simulation of wave propagation. Although scattered wave fluctuations are sources of information, they can hinder the performance of imaging and remote sensing systems. By providing experimental data and numerical models, this volume aids you in evaluating and improving upon the performance of your own systems. 24 cm.

Relativistic numerical hydrodynamics / par Wilson,, James R. Publication : [S.l.] : Cambridge University Press, 2003 . 232 p. ; , Calculations of relativistic hydrodynamics are crucial to several areas of current research in the physics of supernovae and stellar collapse. This book provides an overview of the computational framework in which such calculations have been developed, with examples of applications to real physical systems. Beginning with the development of the equations and differencing schemes for special relativistic hydrodynamics, the book stresses the viability of the Euler-Lagrange approach to most astrophysical problems. It details aspects of solving the Einstein equations together with the fluid dynamics for various astrophysical systems in one, two and three dimensions. 25 cm.

Transport equations for semiconductors par JUngel, Ansga Publication : [S.l.] Springer 2009 . 332 p. , Semiconductor devices are ubiquitous in the modern computer and telecommunications industry. A precise knowledge of the transport equations for electron flow in semiconductors when a voltage is applied is therefore of paramount importance for further technological breakthroughs. In the present work, the author tackles their derivation in a systematic and rigorous way, depending on certain key parameters such as the number of free electrons in the device, the mean free path of the carriers, the device dimensions and the ambient temperature. Accordingly a hierarchy of models is examined which is reflected in the structure of the book: first the microscopic and macroscopic semi-classical approaches followed by their quantum-mechanical counterparts. 25 cm.
