Book Description
Instabilities of fluid flows and the associated transitions between different possible flow states provide a fascinating set of problems that have attracted researchers for over a hundred years. This book addresses state-of-the-art developments in numerical techniques for computational modelling of fluid instabilities and related bifurcation structures, as well as providing comprehensive reviews of recently solved challenging problems in the field.

Book Description
This book offers an introduction to the key ideas, basic analysis, and efficient implementation of discontinuous Galerkin finite element methods (DG-FEM) for the solution of partial differential equations. It covers all key theoretical results, including an overview of relevant results from approximation theory, convergence theory for numerical PDE’s, and orthogonal polynomials. Through embedded Matlab codes, coverage discusses and implements the algorithms for a number of classic systems of PDE’s: Maxwell’s equations, Euler equations, incompressible Navier-Stokes equations, and Poisson- and Helmholtz equations.

Book Description
Useful as a reference for engineers in industry and as an advanced level text for graduate engineering students, Multiphase Flow and Fluidization takes the reader beyond the theoretical to demonstrate how multiphase flow equations can be used to provide applied, practical, predictive solutions to industrial fluidization problems. Written to help advance progress in the emerging science of multiphase flow, this book begins with the development of the conservation laws and moves on through kinetic theory, clarifying many physical concepts (such as particulate viscosity and solids pressure) and introducing the new dependent variable--the volume fraction of the dispersed phase. Exercises at the end of each chapterare provided for further study and lead into applications not covered in the text itself. - Treats fluidization as a branch of transport phenomena - Demonstrates how to do transient, multidimensional simulation of multiphase processes - The first book to apply kinetic theory to flow of particulates - Is the only book to discuss numerical stability of multiphase equations and whether or not such equations are well-posed - Explains the origin of bubbles and the concept of critical granular flow - Presents clearly written exercises at the end of each chapter to facilitate understanding and further study

Book Description
This book is devoted to the phenomenon of quasi-periodic motion in dynamical systems. Such a motion in the phase space densely fills up an invariant torus. This phenomenon is most familiar from Hamiltonian dynamics. Hamiltonian systems are well known for their use in modelling the dynamics related to frictionless mechanics, including the planetary and lunar motions. In this context the general picture appears to be as follows. On the one hand, Hamiltonian systems occur that are in complete order: these are the integrable systems where all motion is confined to invariant tori. On the other hand, systems exist that are entirely chaotic on each energy level. In between we know systems that, being sufficiently small perturbations of integrable ones, exhibit coexistence of order (invariant tori carrying quasi-periodic dynamics) and chaos (the so called stochastic layers). The Kolmogorov-Arnol'd-Moser (KAM) theory on quasi-periodic motions tells us that the occurrence of such motions is open within the class of all Hamiltonian systems: in other words, it is a phenomenon persistent under small Hamiltonian perturbations. Moreover, generally, for any such system the union of quasi-periodic tori in the phase space is a nowhere dense set of positive Lebesgue measure, a so called Cantor family. This fact implies that open classes of Hamiltonian systems exist that are not ergodic. The main aim of the book is to study the changes in this picture when other classes of systems - or contexts - are considered.

Book Description
The GAMM-Commi ttee for Numerical Methods in Fluid Mechanics (GAMM-Fachausschuss für Numerische Methoden in der Strömungsmechanik) has sponsored the organization of a GAMM Workshop dedicated to the numerical simulation of three­ dimensional incompressible unsteady viscous laminar flows to test Navier-Stokes solvers. The Workshop was held in Paris from June 12th to June 14th, 1991 at the Ecole Nationale Superieure des Arts et Metiers. Two test problems were set up. The first one is the flow in a driven-lid parallelepipedic cavity at Re = 3200 . The second problem is a flow around a prolate spheroid at incidence. These problems are challenging as fully transient solutions are expected to show up. The difficulties for meaningful calculations come from both space and temporal discretizations which have to be sufficiently accurate to resol ve detailed structures like Taylor-Görtler-like vortices and the appropriate time development. Several research teams from academia and industry tackled the tests using different formulations (veloci ty-pressure, vortici ty­ velocity), different numerical methods (finite differences, finite volumes, finite elements), various solution algorithms (splitting, coupled, ... ), various solvers (direct, iterative, semi-iterative) with preconditioners or other numerical speed-up procedures. The results show some scatter and achieve different levels of efficiency. The Workshop was attended by about 25 scientists and drove much interaction between the participants. The contributions in these proceedings are presented in alphabetical order according to the first author, first for the cavi ty problem and then for the prolate spheroid problem. No definite conclusions about benchmark solutions can be drawn.

Book Description
In this updated paperback edition, Dale Eickelman and James Piscatori explore how the politics of Islam play out in the lives of Muslims throughout the world. They discuss how recent events such as September 11 and the 2003 war in Iraq have contributed to reshaping the political and religious landscape of Muslim-majority countries and Muslim communities elsewhere. As they examine the role of women in public life and Islamic perspectives on modernization and free speech, the authors probe the diversity of the contemporary Islamic experience, suggesting general trends and challenging popular Western notions of Islam as a monolithic movement. In so doing, they clarify concepts such as tradition, authority, ethnicity, pro-test, and symbolic space, notions that are crucial to an in-depth understanding of ongoing political events. This book poses questions about ideological politics in a variety of transnational and regional settings throughout the Muslim world. Europe and North America, for example, have become active Muslim centers, profoundly influencing trends in the Middle East, Africa, Central Asia, and South and Southeast Asia. The authors examine the long-term cultural and political implications of this transnational shift as an emerging generation of Muslims, often the products of secular schooling, begin to reshape politics and society--sometimes in defiance of state authorities. Scholars, mothers, government leaders, and musicians are a few of the protagonists who, invoking shared Islamic symbols, try to reconfigure the boundaries of civic debate and public life. These symbolic politics explain why political actions are recognizably Muslim, and why "Islam" makes a difference in determining the politics of a broad swath of the world.

Book Description
This book explores the public role of Islam in contemporary world politics. “Public Islam” refers to the diverse invocations and struggles over Islamic ideas and practices that increasingly influence the politics and social life of large parts of the globe. The contributors to this volume show how public Islam articulates competing notions and practices of the common good and a way of envisioning alternative political and religious ideas and realities, reconfiguring established boundaries of civil and social life. Drawing on examples from the late Ottoman Empire, Africa, South Asia, Iran, and the Arab Middle East, this volume facilitates understanding the multiple ways in which the public sphere, a key concept in social thought, can be made transculturally feasible by encompassing the evolution of non-Western societies in which religion plays a vital role.

Book Description
This intensive social biography of a rural Moroccan judge discusses Islamic education, the concept of knowledge it embodies, and its communication from the early years of colonial rule in twentieth-century Morocco to the present. The work sensitively combines the outlooks and perceptions of the author and those of the shrewd and reflective `Abd ar-Rahman, supplementing our knowledge of resurgent militant Islamic movements by describing other popularly supported Islamic attitudes toward the contemporary world.
