The Development of Arithmetic Concepts and Skills: Constructive Adaptive Expertise (Volume in Lea's Mathematical Thinking and Lear Series)
Lawrence Erlbaum | ISSN 080583155X | 2003-01-01 | PDF | 520 Pages | 3,6 Mb
Modern experiments and numerical simulations show that the long-known coherent structures in turbulence take the form of elongated vortex tubes and vortex sheets. The evolution of vortex tubes may result in spiral structures which can be associated with the spectral power laws of turbulence. The mutual stretching of skewed vortex tubes, when they are close to each other, causes rapid growth of vorticity. Whether this process may or may not lead to a finite-time singularity is one of the famous open problems of fluid dynamics.
This book contains the proceedings of the NATO ARW and IUTAM Symposium held in Zakopane, Poland, 2-7 September 2001. The papers presented, carefully reviewed by the International Scientific Committee, cover various aspects of the dynamics of vortex tubes and sheets and of their analogues in magnetohydrodynamics and in quantum turbulence. The book should be a useful reference for all researchers and students of modern fluid dynamics.

Managing Systems Migrations and Upgrades: Demystifying the Technology Puzzle
Publisher: Digital Press | ISBN: 1555582567 | 28 December 2001 | PDF | Pages: 320 | 3.03 MB
Managing Systems Migrations and Upgrades is the perfect book for technology managers who want a rational guide to evaluating the business aspects of various possible technical solutions. Enterprises today are in the middle of the R&D race for technology leadership, with providers who increasingly need to create markets for new technologies while shortening development, implementation, and life cycles.
The cost for the current tempo of technology life cycles is endless change-management controls, organizational chaos, production use of high-risk beta products, and greater potential for failure of existing systems during migration.
Burkey and Breakfield help you answer questions such as, "Is the only solution open to me spending more that the industry average in order to succeed?" and "What are the warning signs that tell me to pass on a particular product offering?" as well as "How can my organization avoid the 'technical death marches' typical of the industry?" This book will take the confusion out of when to make shifts in your systems and help you evaluate the value proposition of these technology changes.
· Provides a methodology for decision making and implementation of upgrades and migrations
· Avoids marketing hype and the "technical herding" instinct
· Offers a tool to optimize technology changes for both staff and customers

Filtering and System Identification: A Least Squares Approach
Cambridge University Press | ISSN: 0521875129 | 2007-05-28 | PDF | 422 Pages | 2,6 Mb
Filtering and system identification are powerful techniques for building models of complex systems. This book discusses the design of reliable numerical methods to retrieve missing information in models derived using these techniques. Emphasis is on the least squares approach as applied to the linear state-space model, and problems of increasing complexity are analyzed and solved within this framework, starting with the Kalman filter and concluding with the estimation of a full model, noise statistics and state estimator directly from the data. Key background topics, including linear matrix algebra and linear system theory, are covered, followed by different estimation and identification methods in the state-space model. With end-of-chapter exercises, MATLAB simulations and numerous illustrations, this book will appeal to graduate students and researchers in electrical, mechanical, and aerospace engineering. It is also useful for practitioners.
