Book Description
A transformation is developed, based upon the scale dependence of turbulent diffusion, that relates temporal and spatial spectra of turbulent kinetic energy. The basic idea is that an eddy diffusivity is appropriate when scales of the flow smaller than a length e and a time tare unresolved. An expression similar to Heisenberg's for eddy diffusivity is used to obtain the connection between e and t necessary to transform temporal spectra into spatial spectra. This transformation reveals a close connection between Webster's Site D spectrum of turbulent kinetic energy in the ocean and Okubo's diagrams of oceanic mixing. Furthermore, all spectra obtained from dimensional arguments satisfy this transformation.

Book Description
"This book studies the interlinking of religious, social and political identities in modern Tamil Nadu. Through interviews with non-Brahmin Srivaisnavas of many castes, but especially belonging to the lower-caste groups, it analyses their histories of discrimination, their negotiation of lived realities, and hopes for the future. The interviews all refer to the history of Srivaisnavism, an historically important Hindu sect in the region, the religion's theology of caste inclusiveness, and history of Brahmin leadership exclusiveness.In addition, the author also addresses colonial changes, Telugu connections, the non-Brahmin movement, Dalit mobilisation, post-Independence caste hierarchies, government policies, party politics, Brahmin reactions, court cases, and inter-religious competition.Turbulent Transformations breaks new ground by highlighting radical non-Brahmin leaders in the colonial period. It probes the Srivaisnava connections of prominent political figures such as Periyar and Jayalalithaa. And it explores the relation of the temples, the state, and the Supreme Court over questions such as 'who is allowed to be a priest'.This book provides insights into new configurations of democracy, caste and modern lived Hinduism. It fills the lacunae created by Brahmin narratives, scholarly studies focused on Tamil Saivism or Christianity, and political and sociological analyses removed from the dynamic pulse of religion in interaction with the non-Brahmin movement over the past century."--

Book Description
Electromagnetic Wave Propagation in Turbulence is devoted to a method for obtaining analytical solutions to problems of electromagnetic wave propagation in turbulence. In a systematic way the monograph presents the Mellin transforms to evaluate analytically integrals that are not in integral tables. Ample examples of application are outlined and solutions for many problems in turbulence theory are given. The method itself relates to asymptotic results that are applicable to a broad class of problems for which many asymptotic methods had to be employed previously.

Book Description
The current downturn may prove more brutal than most previous recessions. It's already hammering companies in markets around the globe. It will test businesses to their fullest-many won't survive. But downturns present strategic opportunities, too. In fact, many more companies achieve dramatic gains during recessions than in normal times. How to ensure your company emerges successful? In Winning in Turbulence, a new volume in the Memo to the CEO series, Bain & Company downturn strategist Darrell Rigby provides the playbook. He presents a powerful framework and diagnostic tool (available in the book and online) for assessing three dimensions of your situation: Your industry's sensitivity: How hard is it hit by this downturn? Your company's strategic position: Are you an industry leader or follower? Your firm's financial position, including cash reserves. The author then explains how to craft an action plan tailored to the situation you've diagnosed, providing tools for: Cutting costs intelligently-sustaining your margins and brand Boosting revenue by refocusing your sales force on the right customers Channeling resources into your core businesses Preparing for bold moves, such as game-changing acquisitions Timely and practical, this book positions you to survive a downturn and emerge stronger once the recovery begins.

Book Description
This textbook is an introduction to wavelet transforms and accessible to a larger audience with diverse backgrounds and interests in mathematics, science, and engineering. Emphasis is placed on the logical development of fundamental ideas and systematic treatment of wavelet analysis and its applications to a wide variety of problems as encountered in various interdisciplinary areas. Topics and Features: * This second edition heavily reworks the chapters on Extensions of Multiresolution Analysis and Newlands’s Harmonic Wavelets and introduces a new chapter containing new applications of wavelet transforms * Uses knowledge of Fourier transforms, some elementary ideas of Hilbert spaces, and orthonormal systems to develop the theory and applications of wavelet analysis * Offers detailed and clear explanations of every concept and method, accompanied by carefully selected worked examples, with special emphasis given to those topics in which students typically experience difficulty * Includes carefully chosen end-of-chapter exercises directly associated with applications or formulated in terms of the mathematical, physical, and engineering context and provides answers to selected exercises for additional help Mathematicians, physicists, computer engineers, and electrical and mechanical engineers will find Wavelet Transforms and Their Applications an exceptionally complete and accessible text and reference. It is also suitable as a self-study or reference guide for practitioners and professionals.
