Resonances In The Earth Ionosphere Cavity. This book on electromagnetic resonance phenomena describes a general approach to physical problems, ways to solve them, and properties of the solutions obtained. Attention is given to the discussion and interpretation of formal and experimental data and their links to global atmospheric conditions such as the dynamics of global thunderstorm activity, variations of the effective height of the lower ionosphere, etc. Schumann resonance is related to worldwide thunderstorm activity, and simultaneously, to global properties of the lower ionosphere. Transverse resonance is predominantly a local phenomenon containing information on the local height and conductivity of the lower ionosphere and on nearby thunderstorm activity. Transient events in ELF-VLF radio propagation are also treated. These are natural pulsed radio signals and/or abrupt changes of manmade VLF radio signals. The transients associated with cloud-to-ionosphere discharges (red sprites, blue jets, trolls) are discussed, and clarification of the underlying physical ideas and their practical applications to pioneer results achieved in the field recently are emphasised.

Resonances. Scattering theory is of interest to physicists and to chemists and has a wide variety of applications, but it also presents a considerable challenge to mathematicians, including numerical analysts. Within the SchrAdinger picture in this volume are collected the various theoretical and mathematical treatments of scattering together with a host of reviews of its applications to atomic and nuclear physics, to surface physics and chemistry, for example trapping of atoms on surfaces, and to amorphous condensed systems. The reviews give a concise and pedagogically useful presentation of the state of the art, and may serve as introductions for newcomers, in particular for graduate students.

Electromagnetic Resonances In Nonlinear Optics. This book is devoted to the numerous phenomena arising from the interplay between electromagnetic resonances and nonlinear optical interactions. These resonances are associated with surface plasmas or guided waves, excited in nonlinear optical resonators such as prisms or grating couplers. Topics include rigorous theories of diffraction by gratings in nonlinear optics, presented in a form ready for numerical implementations; scattering the matrix description in nonlinear optics leading to the phenomological approach based on the use of poles and zeros and other behaviours.

Resonances Of The Raj. During the century of British rule of the Indian subcontinent known as the British Raj, the rulers felt the significant influence of their exotic subjects. Resonances of the Raj examines the ramifications of the intertwined and overlapping histories of Britain and India on English music in the last fifty years of the colonial encounter, and traces the effects of the Raj on the English musical imagination. Conventional narratives depict a one-way influence of Britain on India, with the 'discovery' of Indian classical music occurring only in the post-colonial era. Drawing on new archival sources and approaches in cultural studies, author Nalini Ghuman shows that on the contrary, England was both deeply aware of and heavily influenced by India musically during the Indian-British colonial encounter. Case studies of representative figures, including composers Edward Elgar and Gustav Holst, and Maud MacCarthy, an ethnomusicologist and performer of the era, integrate music directly into the cultural history of the British Raj. Ghuman thus reveals unexpected minglings of peoples, musics and ideas that raise questions about 'Englishness', the nature of Empire, and the fixedness of identity. Richly illustrated with analytical music examples and archival photographs and documents, many of which appear here in print for the first time, Resonances of the Raj brings fresh hearings to both familiar and little-known musics of the time, and reveals a rich and complex history of cross-cultural musical imaginings which leads to a reappraisal of the accepted historiographies of both British musical culture and of Indo-Western fusion.

Quasi Conservative Systems Cycles Resonances And Chaos. This monograph presents the theory of nonconservative systems close to nonlinear integrable ones. With the example of concrete quasi-conservative systems close to nonintegrable ones, the results of numerical analysis are given, and the problem of applying the small parameter method is analyzed. The fundamantal part of the book deals with the investigation of the perturbable systems. Both autonomous and nonautonomous (periodic in time) systems are considered. The global analysis of systems close to the two-dimensional Hamiltonian ones takes a central place in the text. This global analysis includes the solution to problems such as the limit cycles, resonances, and nonregular dynamics. For the autonomous systems, one should note the analysis of the standard (Duffing and pendulum) equations including the solution to the “weakened” 16 Hilbert's problem, and for the nonautonomous systems one should note the mathematical foundations of the theory of synchronization of oscillations (the existence of new regimes, and the passage of invariant tori across the resonance zones under the change of detuning). The presentation is accompanied by examples.
