Cet ouvrage traite des théorèmes fondamentaux de l'analyse (convergence, continuité, calcul différentiel et intégral à une et plusieurs variables) avec grand soin pédagogique, une centaine de dessins, d'exemples et de contre-exemples. Pour une meilleure compréhension du sujet, il commence avec des calculs anciens de problèmes géometriques et mécaniques, qui ont conduit aux séries infinies, dérivées, intégrales, équations différentielles. Ainsi ce volume nous fait découvrir "l'analyse au fil de l'histoire". De nombreuses motivations et remarques historiques enrichissent le texte.
Numerical methods that preserve properties of Hamiltonian systems, reversible systems, differential equations on manifolds and problems with highly oscillatory solutions are the subject of this book. A complete self-contained theory of symplectic and symmetric methods, which include Runge-Kutta, composition, splitting, multistep and various specially designed integrators, is presented and their construction and practical merits are discussed. The long-time behaviour of the numerical solutions is studied using a backward error analysis (modified equations) combined with KAM theory. The book is illustrated by many figures, it treats applications from physics and astronomy and contains many numerical experiments and comparisons of different approaches.
A concise and authoritative introduction to scanning electron microscopy in the biological sciences In A Practical Guide to Scanning Electron Microscopy distinguished electron microscopist Gerhard Wanner delivers a practical handbook for biological scientists working with microbial, plant, and animal cells and tissues, enabling them to successfully apply scanning electron microscopy (SEM) to their object of study. The book begins with an introduction to the principles of electron microscopy and the operation of electron microscopes before moving on to describe the preparation and mounting of specimens. It also explores the process of recoding images and their subsequent analysis, along with a wide range of advanced microscopy techniques, including cryo-SEM, FIB-SEM tomography, and stereo-SEM. Scanning Electron Microscopy in the Biosciences contains hundreds of carefully selected microscopic images, as well as hands-on, step-by-step guidance required to perform a successful TEM experiment. Readers will also Perfect for cell biologists and microbiologists, A Practical Guide to Scanning Electron Microscopy in the Biosciences also belongs in the libraries of neurobiologists and biophysicists.
