Book Synopsis Fractal Analysis by : Fernando Brambila
Download or read book Fractal Analysis written by Fernando Brambila and published by BoD – Books on Demand. This book was released on 2017-06-14 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fractal analysis has entered a new era. The applications to different areas of knowledge have been surprising. Let us begin with the fractional calculus-fractal geometry relationship, which allows for modeling with extreme precision of phenomena such as diffusion in porous media with fractional partial differential equations in fractal objects. Where the order of the equation is the same as the fractal dimension, this allows us to make calculations with enormous precision in diffusion phenomena-particularly in the oil industry, for new spillage prevention. Main applications to industry, design of fractal antennas to receive all frequencies and that is used in all cell phones, spacecraft, radars, image processing, measure, porosity, turbulence, scattering theory. Benoit Mandelbrot, creator of fractal geometry, would have been surprised by the use of fractal analysis presented in this book: "Part I: Petroleum Industry and Numerical Analysis"; "Part II: Fractal Antennas, Spacecraft, Radars, Image Processing, and Measure"; and "Part III: Scattering Theory, Porosity, and Turbulence." It's impossible to picture today's research without fractal analysis.

This book was released on 1994 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'EPANDAGE DES BOUES DE CURAGE DES COURS D'EAU SUR LES TERRES AGRICOLES EST UNE PRATIQUE COURANTE A TRAVERS LE MONDE. SI CES BOUES CONTIENNENT PARFOIS DES AMENDEMENTS UTILES, ELLES PEUVENT EGALEMENT, DE PART LES ELEMENTS TOXIQUES QU'ELLES RENFERMENT, AVOIR DES EFFETS NEFASTES SUR L'ENVIRONNEMENT. CE TRAVAIL VISAIT A MIEUX COMPRENDRE LE DEVENIR, PAR TRANSFERT HYDRIQUE, DE QUELQUES MICROPOLLUANTS INORGANIQUES (ZN, PB, CR, CD, CU ET NI) DANS LA ZONE NON SATUREE DU SOL. L'EVALUATION DES RISQUES DE CONTAMINATION DES SOLS ET DES NAPPES A ETE ABORDE A PARTIR DE TROIS AXES PRINCIPAUX: UNE APPROCHE EXPERIMENTALE SUR SITE NATUREL, UNE RECHERCHE DE PARAMETRES AU LABORATOIRE, UNE ETUDE PAR MODELISATION. APRES LE CHOIX DU SITE, L'APPROCHE EXPERIMENTALE SUR UNE PARCELLE DE SOL OU A ETE REALISE UN EPANDAGE A CONSISTE A ETUDIER L'INFILTRATIONS ET LES MOUVEMENTS D'EAU RESPONSABLES DU TRANSFERT DE MICROPOLLUANTS. LE SUIVI DE LA POLLUTION PROPREMENT DITE EST EFFECTUE A LA FOIS DANS LE SOL ET DANS L'EAU D'INFILTRATION. ON RELEVE UNE PERTE PAR TRANSFERT HYDRIQUE DE L'ORDRE DE 0.05% DU STOCK METALLIQUE INITIAL DANS LA BOUE. TANDIS QUE LES TENEURS EN ZN, NI ET CR PAR EXEMPLE, AUGMENTENT DE FACON PLUS IMPORTANTE DANS LE PREMIER METRE DE SOL. LES PRINCIPAUX PARAMETRES DETERMINES AU LABORATOIRE SONT SOIT DE NATURE PHYSIQUE SOIT DE NATURE CHIMIQUE. DES ESSAIS DE LIXIVIATION SUR LES COLONNES DE SOL ET LA DETERMINATION DES COEFFICIENTS DE PARTAGE CONFIRMENT LES RESULTATS DU TERRAIN A SAVOIR, UNE RETENTION DES METAUX PAR LE SOL ET LA BOUE. LE TRACAGE PERMET DE METTRE EN EVIDENCE LES VITESSES REELLES (DE PORE) ET LA POROSITE EQUIVALENTE. UNE ETUDE PAR MODELISATION EST REALISEE EN UTILISANT UN MODELE EXISTANT LEACHM. LA PARTIE ECOULEMENT EST BIEN CALEE. PAR CONTRE, LA PARTIE TRANSPORT RESTE A PARFAIRE NOTAMMENT AU NIVEAU DES MECANISMES D'ECHANGES, METTANT EN EVIDENCE L'EXISTANCE DE VOIES DE TRANSFERTS NON PRIS EN COMPTE PAR LE MODELE. MALGRE LA FAIBLE IMPORTANCE DES TRANSFERTS CONSTATES PAR VOIE HYDRIQUE, IL EST DIFFICILE DE CONCLURE SUR L'ABSENCE DE RISQUE A PLUS LONG TERME COMPTE TENU DE LA DUREE LIMITEE DES OBSERVATIONS

Book Synopsis Recent Advances in Radial Basis Function Collocation Methods by : Wen Chen
Download or read book Recent Advances in Radial Basis Function Collocation Methods written by Wen Chen and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book surveys the latest advances in radial basis function (RBF) meshless collocation methods which emphasis on recent novel kernel RBFs and new numerical schemes for solving partial differential equations. The RBF collocation methods are inherently free of integration and mesh, and avoid tedious mesh generation involved in standard finite element and boundary element methods. This book focuses primarily on the numerical algorithms, engineering applications, and highlights a large class of novel boundary-type RBF meshless collocation methods. These methods have shown a clear edge over the traditional numerical techniques especially for problems involving infinite domain, moving boundary, thin-walled structures, and inverse problems. Due to the rapid development in RBF meshless collocation methods, there is a need to summarize all these new materials so that they are available to scientists, engineers, and graduate students who are interest to apply these newly developed methods for solving real world’s problems. This book is intended to meet this need. Prof. Wen Chen and Dr. Zhuo-Jia Fu work at Hohai University. Prof. C.S. Chen works at the University of Southern Mississippi.

Download or read book MEGA-CRISES written by Ira Helsloot and published by Charles C Thomas Publisher. This book was released on 2012-08-01 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in turbulent times with continents and nations facing ever-heightening risks such as natural disasters, intense and protracted conflicts, terrorism, corporate crises, cyber threats to infrastructures and mega-events. We are witnessing the rise of mega-crises and a new class of adversity with many unknowns. The prospect of mega-crises presents professionals and students in the field of crisis management with four major tasks. First, they should engage in “deep thinking” about the causes of the increasing occurrence of mega-crises. Second, they should identify and work through the dominant trends which complicate contemporary crisis management. Third, they should upgrade institutional crisis management capacity. Fourth, they should improve societal resilience since no institutional complex can mitigate or manage these mega-crisis on its own. This book is divided into four primary parts, each of which looks at one facet of mega-crises. Part I focuses on the concept of a mega-crisis and mega-crisis management; Part II examines crisis management of mega-natural disasters; Part III evaluates crisis management of man-made mega-crises; and Part IV identifies mega-threats and vulnerabilities. Additional major topics include Hurricane Katrina; Hurricane Gustav; the London Bombings; the Mumbai Terrorist Attacks of July 7, 2005; corporate meltdowns; the subprime crisis; the Olympic Games; electricity grids; global climate change; the Dutch Delta; risks to food security; and mega-crises and the Internet. This comprehensive text will provide practitioners and academics with the results of an across-the-board research effort in the prospects, nature, characteristics, and the effects of mega-crises.

Book excerpt: A NATO Advanced Study Institute on Approximation Theory and Spline Functions was held at Memorial University of Newfoundland during August 22-September 2, 1983. This volume consists of the Proceedings of that Institute. These Proceedings include the main invited talks and contributed papers given during the Institute. The aim of these lectures was to bring together Mathematicians, Physicists and Engineers working in the field. The lectures covered a wide range including ~1ultivariate Approximation, Spline Functions, Rational Approximation, Applications of Elliptic Integrals and Functions in the Theory of Approximation, and Pade Approximation. We express our sincere thanks to Professors E. W. Cheney, J. Meinguet, J. M. Phillips and H. Werner, members of the International Advisory Committee. We also extend our thanks to the main speakers and the invi ted speakers, whose contri butions made these Proceedings complete. The Advanced Study Institute was financed by the NATO Scientific Affairs Division. We express our thanks for the generous support. We wish to thank members of the Department of Mathematics and Statistics at MeMorial University who willingly helped with the planning and organizing of the Institute. Special thanks go to Mrs. Mary Pike who helped immensely in the planning and organizing of the Institute, and to Miss Rosalind Genge for her careful and excellent typing of the manuscript of these Proceedings.
