Transition, Turbulence, and Noise Springer-Verlag New York Inc.

Turbulence takes place in most flow situations whethertheyoccur naturally or in technological systems. Therefore, considerable effort is being expended in an attempt to understand the phenomenon of turbulence. The recent discovery ofcoherent structure in turbulent shear flows and the modem developments in computer capabilities have revolutionized research work in turbulence. There is a strong evidence that the coherent structure in turbulent shear flows is reminiscent of nonlinear stability waves. As such, the interest in nonlinear stability waves has increased not only for the understandingofthe latterstages of the laminar-turbulent transition process, but also for understanding the coherent structures in turbulent flows. Also. the advances in computers have made direct numerical simulation possible at Low-Reynolds numbers and large-eddy simulation possible at high Reynolds numbers. This made first-principles prediction of turbulence-generated noise feasible. Therefore, this book aims at presenting a graduate-level introductory study of turbulence while accounting for such recent views of concern to researchers. This book is an outgrowth oflecture notes on the subject offered to graduate students in engineering. The book should be of interest to research engineers and graduatestudents in science and engineering. The theoretical basis presented is sufficient not only for studying the specialized literature on turbulence but also for theoretical investigations on the subject.

Faster Algorithms via Approximation Theory now publishers Inc

Approximation Theory and Fast Algorithms illustrates how classical and modern results from approximation theory play a crucial role in obtaining results that are relevant to the emerging theory of fast algorithms today. For example, it shows how to compute good approximations to matrix-vector products such as Asv; A-1v and exp(-A)v for any matrix A and a vector v.6. It also shows how to speed up algorithms that compute the top few eigenvalues and eigenvectors of a symmetric matrix A. Such primitives are useful for performing several fundamental computations quickly, such as random walk simulation, graph partitioning, solving linear system of equations, and combinatorial approaches to solving semi-definite programs. The algorithms for computing these primitives perform calculations of the form Bu where B is a matrix closely related to A (often A itself) and u is some vector. A key feature of these algorithms is that if the matrix-vector product for A can be computed quickly, e.g., when A is sparse, then Bu can also be computed in essentially the same time. This makes such algorithms particularly relevant for handling the problem of big data.Such matrices capture either numerical data or large graphs, and it is inconceivable to be able to compute much more than a few matrix-vector products on matrices of this size.
