Discrete Wavelet Transform is a wavelet (DWT) transform that is widely used in numerical and functional analysis. Its key advantage over more traditional transforms, such as the Fourier transform, lies in its ability to offer temporal resolution, i.e. it captures both frequency and location (or time) information. This book presents a succinct compendium of some of the more recent variants of DWTs and their use to come up with solutions to an array of problems transcending the traditional application areas of image/video processing and security to the relatively newer areas of medicine, artificial intelligence, power systems and telecommunications. The first of the two sections of this book contains three chapters devoted to traditional applications of DWTs in digital image compression, copyright protection and video resolution enhancement. The second section, comprising of five chapters, is devoted to variants of the DWT and their applications in humanoid-robot vision systems; modeling and simulation recognition of physiological and behavioral traits through human gait and facial images; assessment of agitation and sedation in intensive care patients; maximization of power control systems; and, finally, in demodulation of FM data in free-space optical control systems.

Chaos is considered as one of the most important concepts in modern science. It originally appeared only in computer simulation (the famous Lorenz equation of 1963), but this changed with the introduction of Chua's oscillator (1986) - a simple electronic circuit with the ability to generate a vast range of chaotic behaviors. With Chua's circuit, chaos became a physical phenomenon, readily understood and represented in mathematical language. Yet, even so, it is still difficult for the non-specialist to appreciate the full variety of behaviors that the system can produce.This book aims to bridge

What happens in an established practice or work setting when a novel artifact or tool for doing work changes the familiar work routines? Any unexpected event, or change, or technological innovation creates a discontinuity; organizations and individuals must reframe taken-for-granted assumptions and practices and reposition themselves. To study innovation as a phenomenon, then, we must search for situations of discontinuity and rupture and explore them in depth. In Shifting Practices, Giovan Francesco Lanzara does just that, and discovers that disruptions and discontinuities caused by the introduction of new technologies often reveal aspects of practice not previously observed. After discussing methodological and research issues, Lanzara presents two in-depth studies focusing on processes of design and innovation in two different practice settings: music education and criminal justice. In the first, he works with the music department of a major American university to develop Music LOGO, a computer system that allows students to explore musical structures with simple, composition-like exercises and experiments. In the second, he works with the Italian court system in the design and use of video technology for criminal trials. In both cases, drawing on anecdotes and examples as well as theory and analysis, he traces the new systems from design through implementation and adoption. Finally, Lanzara considers the researcher's role, and the relationship -- encompassing empathy, vulnerability, and temporality -- between the reflective researcher and actors in the practice setting.
