Boundary Element Method for Impedance and Optical Tomoggraphy Politechnika Warszawska

MEDYCYNA

There is a lot of excellent books devoted the Boundary Element Method (BEM). That is why I would not dare to write one more. The main goal of this book is only to show the problems of modelling the forward problems of Diffusive Optical Tomography (DOT) or Electrical Impedance Tomography (EIT) when the Boundary Element is used in 2D or 3D space. The modern Inverse Problems are solved by the iterative process in which we have to solve many times the forward problems for which the design parameters are improved due to the Sensitivity Analysis (SA). The scope of this book is limited to the forward problems and methods presentation of their effective solution in 2D and 3D space with the aid of the Boundary Element Method. The special attention was paid to the basic of the BEM because majority of the monographes devoted this method, do not pay enough attention to the problems of singular integrals integrations. This problem is already solved by many famous authors ( maybe with the exception of the 3D Galerkin approach) but is spread in the literature, in most cases, not easily accessible. That is why it seems to be reasonable to present this problem in full details in this work. A lot of attention was devoted to the problem of modelling of the infant head for the DOT. The BEM seems to be more elastic tool than the FEM. This work tries to prove this opinion. Spis treści: List of symbols Introduction 1. Two-dimensional potential problems 1.1. Introduction 1.2.

Advanced Mathematical Methods for Scientists and Engineers I Springer, Berlin

Książki / Literatura obcojęzyczna

A clear, practical and self-contained presentation of the methods of asymptotics and perturbation theory for obtaining approximate analytical solutions to differential and difference equations. Aimed at teaching the most useful insights in approaching new problems, the text avoids special methods and tricks that only work for particular problems. Intended for graduates and advanced undergraduates, it assumes only a limited familiarity with differential equations and complex variables. The presentation begins with a review of differential and difference equations, then develops local asymptotic methods for such equations, and explains perturbation and summation theory before concluding with an exposition of global asymptotic methods. Emphasizing applications, the discussion stresses care rather than rigor and relies on many well-chosen examples to teach readers how an applied mathematician tackles problems. There are 190 computer-generated plots and tables comparing approximate and exact solutions, over 600 problems of varying levels of difficulty, and an appendix summarizing the properties of special functions.This book gives a clear, practical and self-contained presentation of the methods of asymptotics and perturbation theory and explains how to use these methods to obtain approximate analytical solutions to differential and difference equations. These methods allow one to analyze physics and engineering problems that may not be solvable in closed form and for which brute-force numerical methods may not converge to useful solutions.

This textbook provides a clear introduction to both the theory and application of fluid dynamics, and will be suitable for all undergraduates coming to the subject for the first time. Prerequisites are few: a basic knowledge of vector calculus, complex analysis, and simple methods for solving differential equations are all that is needed. Throughout, numerous exercises (with hints and answers) illustrate the main ideas and serve to consolidate the reader's understanding of the subject. The book's wide scope (including inviscid and viscous flows, waves in fluids, boundary layer flow, and instability in flow) and frequent references to experiments and the history of the subject, ensures that this book provides a comprehensive and absorbing introduction to the mathematical study of fluid behaviour.

Flight Vehicle Aerodynamics MIT Press Ltd

Książki / Literatura obcojęzyczna

This book offers a general overview of the physics, concepts, theories, and models underlying the discipline of aerodynamics. A particular focus is the technique of velocity field representation and modeling via source and vorticity fields and via their sheet, filament, or point-singularity idealizations. These models provide an intuitive feel for aerodynamic flow-field behavior and are the basis of aerodynamic force analysis, drag decomposition, flow interference estimation, and other important applications. The models are applied to both low speed and high speed flows. Viscous flows are also covered, with a focus on understanding boundary layer behavior and its influence on aerodynamic flows. The book covers some topics in depth while offering introductions and summaries of others. Computational methods are indispensable for the practicing aerodynamicist, and the book covers several computational methods in detail, with a focus on vortex lattice and panel methods. The goal is to improve understanding of the physical models that underlie such methods.The book also covers the aerodynamic models that describe the forces and moments on maneuvering aircraft, and provides a good introduction to the concepts and methods used in flight dynamics. It also offers an introduction to unsteady flows and to the subject of wind tunnel measurements. The book is based on the MIT graduate-level course "Flight Vehicle Aerodynamics" and has been developed for use not only in conventional classrooms but also in a massive open online course (or MOOC) offered on the pioneering MOOC platform edX. It will also serve as a valuable reference for professionals in the field. The text assumes that the reader is well versed in basic physics and vector calculus, has had some exposure to basic fluid dynamics and aerodynamics, and is somewhat familiar with aerodynamics and aeronautics terminology.
