This monograph systematically develops and considers the so-called "dressing method" for solving differential equations (both linear and nonlinear), a means to generate new non-trivial solutions for a given equation from the (perhaps trivial) solution of the same or related equation. Throughout, the text exploits the "linear experience" of presentation, with special attention given to the algebraic aspects of the main mathematical constructions and to practical rules of obtaining new solutions.

Judging the brightness and colour of light has long been contentious. Alternately described as 'impossible' and 'routine', it was beset by problems both technical and social. How trustworthy could such measurements be? Was the 'best' standard of intensity a gas lamp, an incandescent bulb or a glowing pool of molten metal? And how much did the answers depend on the background of the specialist? This book is a history of the hidden workings of physical science - a technical endeavour embedded in a social context. It argues that this 'undisciplined' subject, straddling academia, commerce, and regulation, may be typical not only of 20th century science, but of its future.

A single source that covers both absorption and scattering in a comprehensive format that maintains balance between both subject areas. Opens with a review of basic theory and then delves into optical properties of bulk matter and optical properties of particles.

Revised and updated, this second edition first explains heuristically the physics of acousto-optics before presenting the mathematics of the formal theory. The material is integrated to illustrate and promote the development of new ideas, concepts, theories, inventions and devices. The text also offers sections on the Near-Bragg regime and curved sound wave fronts, coverage of the numerical approach, selected applications, coverage of anisotropic Bragg diffraction, and material on spectral formalisms.

This compilation of the works and insights of various key scientists and engineers in this area addresses the current and future trends of scenarios for employing adaptive antenna arrays in communication systems. Ideal as a quick reference for engineers, researchers, advanced undergraduate and postgraduate students.

Magnetic Resonance Imaging (MRI) is a growing technique that has the potential to greatly improve medical diagnosis. The challenge of using MRI in medicine rests in the development of new generations of contrast media using targeted nanoparticles to improve signal detection at the molecular level, as well as in the improvement of image processing algorithms for the increased detection of disease. Advanced Image Processing in Magnetic Resonance Imaging uses a signal processing approach to describe the fundamentals of MRI. The authors cover physical MRI fundamentals, image segmentation and quantitative analysis, modeling and analysis in perfusion images, functional signal analysis, and perspectives.

Recent progress has been made in understanding light-induced degradation in amorphous semiconductors, which is seen as the most limiting problem in device applications. This book compiles recent knowledge on the structural, electronic, and optical properties of these materials. Since amorphous materials differ significantly from their crystalline counterparts, the field needs to address some of the problems associated with the validity of the effective mass approximation, whether K is a good quantum number, and the concepts of phonons and excitons. This monograph effectively addresses those issues, providing a full treatment of both experimental and theoretical studies.

The birth of quantum electronics in the middle of the 20th century and the subsequent discovery of the laser led to new trends in physics and a number of photonic technolgies. Advances in Laser Physics is dedicated to Peter Franken, a pioneer of nonlinear optics, and includes papers by the founders of quantum electronics, Aleksandr Prokhorov, Nicolaas Blombergen, and Norman Ramsey. The topics covered range from astronomy to nuclear and semiconductor physics, and from fundamental problems in quantum mechanics to applications in novel laser materials and nanoscience.
