Across The Waves

"Per the UK publisher William Collins's promotional copy: "There is a quarter of this planet which is often forgotten in the histories that are told in the West. This quarter is an oceanic one, pulsating with winds and waves, tides and coastlines, islands and beaches. The Indian and Pacific Oceans constitute that forgotten quarter, brought together here for the first time in a sustained work of history." More specifically, Sivasundaram's aim in this book is to revisit the Age of Revolutions and Empire from the perspective of the Global South. Waves Across the South ranges from the Arabian Sea across the Indian Ocean to the Bay of Bengal, and onward to the South Pacific and Australia's Tasman Sea. As the Western empires (Dutch, French, but especially British) reached across these vast regions, echoes of the European revolutions rippled through them and encountered a host of indigenous political developments. Sivasundaram also opens the door to new and necessary conversations about environmental history in addition to the consequences of historical violence, the extraction of resources, and the indigenous futures that Western imperialism cut short"--

In 1931, the United States and France embarked on a broadcasting partnership built around radio. Over time, the transatlantic sonic alliance came to personify and to shape American-French relations in an era of increased global media production and distribution. Drawing on a broad range of American and French archives, Derek Vaillant joins textual and aural materials with original data analytics and maps to illuminate U.S.-French broadcasting's political and cultural development. Vaillant focuses on the period from 1931 until France dismantled its state media system in 1974. His analysis examines mobile actors, circulating programs, and shifting governmental and other institutions shaping international radio's use in times of war and peace. He explores the extraordinary achievements, the miscommunications and failures, and the limits of cooperation between America and France as they shaped a new media environment. Throughout, Vaillant explains how radio's power as an instantaneous mass communications tool produced, legitimized, and circulated various notions of states, cultures, ideologies, and peoples as superior or inferior.

Mexican Waves is the fascinating history of how borderlands radio stations shaped the identity of an entire region as they addressed the needs of the local population and fluidly reached across borders to the United States. In so doing, radio stations created a new market of borderlands consumers and worked both within and outside the constraints of Mexican and U.S. laws. Historian Sonia Robles examines the transnational business practices of Mexican radio entrepreneurs between the Golden Age of radio and the early years of television history. Intersecting Mexican history and diaspora studies with communications studies, this book explains how Mexican radio entrepreneurs targeted the Mexican population in the United States decades before U.S. advertising agencies realized the value of the Spanish-language market. Robles’s robust transnational research weaves together histories of technology, performance, entrepreneurship, and business into a single story. Examining the programming of northern Mexican commercial radio stations, the book shows how radio stations from Tijuana to Matamoros courted Spanish-language listeners in the U.S. Southwest and local Mexican audiences between 1930 and 1950. Robles deftly demonstrates Mexico’s role in creating the borderlands, adding texture and depth to the story. Scholars and students of radio, Spanish-language media in the United States, communication studies, Mexican history, and border studies will see how Mexican radio shaped the region’s development and how transnational listening communities used broadcast media’s unique programming to carve out a place for themselves as consumers and citizens of Mexico and the United States.

50th Anniversary Edition of Across the Waves Sports Club Inc.

This title was first published in 2001. The new edition of Science Foundations provides comprehensive coverage of single- and double-award GCSE science. It is fully revised and updated to match the new GCSE specifications, for teaching from September 2001. It contains all the material required for the foundation and higher tiers, with clear progression and explicit differentiation. 'Higher tier only' material is clearly marked in separate spreads. The language level is carefully controlled, with illustrations and layout specifically designed to make the concepts accessible. There are frequent opportunities for students to confirm their understanding of each key idea as it is introduced, via short questions and summary passages on each spread. The books include guidance for students on how to prepare for and answer their GCSE examinations, and a glossary of key words for ease of reference.

The topic of surface waves lies at the interface between a number of disci plines - physics, theoretical and applied mechanics, electroacoustics, ap plied mathematics, surface science and seismology. This volume, based on papers delivered at European Mechanics Colloquium 226, reflects this diversity in approach and background, while showing strong links between phenomena arising from different fields. The emphasis is on recent de velopments such as nonlinear and other nonclassical effects,which have great importance for both pure science and for applications such as signal processing, nondestructive evaluation and seismic studies. In recent years there has been considerable progress in the mathe matical treatment of nonlinear effects, of viscoelastic and of more novel constitutive effects which modify the predictions of linear elastic and piezo electric theory for surface acoustic wave (SAW) propagation. A number of these themes serve to group the contents of this volume. Part I contains recent advances in the rigorous mathematical treatment of nonlinearity, together with a paper giving experimental results showing the need for further theoretical development. Part II deals with anisotropic elasticity, showing that even the linear theory presents many possible behaviours, which are still not fully categorized.

The primary objective of Foundations of Stress Waves is to give the reader an understanding of stress wave behaviour while taking into account the dynamic constitutive equations of elastic-plastic solids. The author has combined a 'materials characteristics' approach with a 'singularity surface' approach in this work, which readers will find to be a novel and unique route to solving their problems. Helps engineers understand the effects and behavior of stress waves in various materials Aids in the process of engineering design, testing, and evaluation

This book is the first of its kind devoted to surface waves propagating across an external static magnetic field at harmonics of the electron cyclotron frequency. Based on comprehensive theoretical studies carried out over the course of about forty years, it presents unique material on various characteristics of these transverse waves, namely, dispersion properties and their dependence on numerous design peculiarities of plasma waveguides; damping due to interaction with the plasma surface (the kinetic channel) and collisions between plasma particles (the Ohmic channel); interaction with flows of charged particles moving above the plasma surface; parametric excitation due to the effect of an external radiofrequency field; and their power transfer for sustaining gas discharges. Clarifying numerous complicated mathematical issues it is a valuable resource for postgraduate students and experts in plasma physics, electromagnetic waves, and the kinetic theory of plasmas.
