Two-dimensional wavelets offer a number of advantages over discrete wavelet transforms when processing rapidly varying functions and signals. In particular, they offer benefits for real-time applications such as medical imaging, fluid dynamics, shape recognition, image enhancement and target tracking. This book introduces the reader to 2-D wavelets via 1-D continuous wavelet transforms, and includes a long list of useful applications. The authors then describe in detail the underlying mathematics before moving on to more advanced topics such as matrix geometry of wavelet analysis, three-dimensional wavelets and wavelets on a sphere. Throughout the book, practical applications and illustrative examples are used extensively, ensuring the book's value to engineers, physicists and mathematicians alike.

This volume aims to aid the integration of a company's environmental and business interests, thereby enhancing corporate eco-efficiency in terms of reducing environmental costs or making one's product more competitive. It presents a number of EMA frameworks that companies can take as a basis for implementing their own specific EMA structures. Besides discussing environmental accounting issues within conventional management accounting, it gives a detailed picture of materials flow (cost) accounting as an alternative way of looking at the ecology-economy relationships at the corporate level. A case study shows how a large company (Siemens) applies materials flow accounting and what benefits it entails. Applying EMA in an effective way may require the use of information systems. The book discusses the pros and cons of different strategies in this area; one may opt for a total integrated solution, partially integrated solutions or for a stand-alone system. Governments may have good reasons to promote the application of EMA.The use of economic instruments to internalise environmental externalities (norms, ecotaxes and tradable permits) can be much more effective if the incentives they produce are not frustrated by a lack of adequate cost accounting. EMA can be of great importance here. The book discusses a number of these issues, giving information on how international and national organisations (such as in Japan) have taken steps to promote the adoption of EMA by the business community. A final section presents a number of different topics such as how environmental costs can be of help in defining environmental management strategies, and how to take environmental performance indicators a step further by developing sustainability indicators for product chains. A final chapter explores a possible theoretical foundation for research on why, how and to what extent companies adopt EMA. Such research may help to turn available insights as to what EMA should be into effective EMA strategies.

This second edition is fully updated, covering in particular new types of coherent states (the so-called Gazeau-Klauder coherent states, nonlinear coherent states, squeezed states, as used now routinely in quantum optics) and various generalizations of wavelets (wavelets on manifolds, curvelets, shearlets, etc.). In addition, it contains a new chapter on coherent state quantization and the related probabilistic aspects. As a survey of the theory of coherent states, wavelets, and some of their generalizations, it emphasizes mathematical principles, subsuming the theories of both wavelets and coherent states into a single analytic structure. The approach allows the user to take a classical-like view of quantum states in physics.Starting from the standard theory of coherent states over Lie groups, the authors generalize the formalism by associating coherent states to group representations that are square integrable over a homogeneous space; a further step allows one to dispense with the group context altogether. In this context, wavelets can be generated from coherent states of the affine group of the real line, and higher-dimensional wavelets arise from coherent states of other groups. The unified background makes transparent an entire range of properties of wavelets and coherent states. Many concrete examples, such as coherent states from semisimple Lie groups, Gazeau-Klauder coherent states, coherent states for the relativity groups, and several kinds of wavelets, are discussed in detail. The book concludes with a palette of potential applications, from the quantum physically oriented, like the quantum-classical transition or the construction of adequate states in quantum information, to the most innovative techniques to be used in data processing.Intended as an introduction to current research for graduate students and others entering the field, the mathematical discussion is self-contained. With its extensive references to the researchliterature, the first edition of the book is already a proven compendium for physicists and mathematicians active in the field, and with full coverage of the latest theory and results the revised second edition is even more valuable.

The idea of the workshop on Functional Integration, Theory and Applications, held in Louvain-Ia-Neuve from November 6 to 9 1979, was to put in close and informal contact, during a few days, active workers in the field. There is no doubt now that functional integration is a tool that is being applied in all branches of modern physics. Since the earlier works of Dirac and Feynman enormous progress has been made, but unfortunately we lack still a unifying and rigo­ rous mathematical framework to account for all the situations in which one is interested. We are then in presence of a rapid­ ly changing field in which new achievements, proposals, and points of view are the normal pattern. Considering this state of affairs we have decided to order the articles starting from the more fundamental and ambitious from the point of view of mathematical rigour, followed by ar­ ticles in which the main interest is the application to con­ crete physical situations. It is obvious that this ordering should not be taken too seriously since in many cases there will be an interplay of both objects.
