Ce livre pr sente de nouvelles techniques bas es sur les statistiques d'ordre sup rieur, d velopp s pour deux domaines sp cifiques: la g ophysique et l' lectrotechnique. Ces techniques permettent de sortir du cadre conventionnel de traitement afin d'aboutir de nouveaux outils et algorithmes. Ainsi, en g ophysique, nous montrons que le r sultat de la s paration d'ondes sismiques dans le domaine temps-distance, obtenu classiquement par l'utilisation de la d composition en valeurs singuli res, est am lior en utilisant une m thode bas e sur l'analyse en composantes ind pendantes. Cet algorithme peut tre tendu la g n ralisation de la d composition en valeurs singuli res aux tableaux tridimensionnels. En lectrotechnique, afin de caract riser les composantes harmoniques des signaux de courant issus d'une machine asynchrone triphas e, nous tudions ces types de signaux par une analyse spectrale l'ordre deux et trois. Nous d finissons ensuite un outil d'analyse spectrale l'ordre quatre d nomm le kurtosis spectral. Ce nouvel outil nous permet d'acc der des informations compl mentaires celle donn e par l'analyse spectrale l'ordre deux.

The dimmed outlines of phenomenal things all into one another unless we put on the merge focusing-glass of theory, and screw it up some times to one pitch of definition and sometimes to another, so as to see down into different depths through the great millstone of the world James Clerk Maxwell (1831 - 1879) For a long time after the foundation of the modern theory of electromag netism by James Clerk Maxwell in the 19th century, the mathematical ap proach to electromagnetic field problems was for a long time dominated by the analytical investigation of Maxwell's equations. The rapid development of computing facilities during the last century has then necessitated appropriate numerical methods and algorithmic tools for the simulation of electromagnetic phenomena. During the last few decades, a new research area "Computational Electromagnetics" has emerged com prising the mathematical analysis, design, implementation, and application of numerical schemes to simulate all kinds of relevant electromagnetic pro cesses. This area is still rapidly evolving with a wide spectrum of challenging issues featuring, among others, such problems as the proper choice of spatial discretizations (finite differences, finite elements, finite volumes, boundary elements), fast solvers for the discretized equations (multilevel techniques, domain decomposition methods, multipole, panel clustering), and multiscale aspects in microelectronics and micromagnetics.

Covering basic physical concepts, experimental methods, and applications, this book is an indispensable text on the fascinating science of magnetism, and an invaluable source of practical reference data. Accessible, authoritative, and assuming undergraduate familiarity with vectors, electromagnetism and quantum mechanics, this textbook is well suited to graduate courses. Emphasis is placed on practical calculations and numerical magnitudes – from nanoscale to astronomical scale – focussing on modern applications, including permanent magnet structures and spin electronic devices. Each self-contained chapter begins with a summary, and ends with exercises and further reading. The book is thoroughly illustrated with over 600 figures to help convey concepts and clearly explain ideas. Easily digestible tables and data sheets provide a wealth of useful information on magnetic properties. The 38 principal magnetic materials, and many more related compounds, are treated in detail.
