Planetary Noise

Thanks to the potential of reducing fuel consumption and emissions, hybrid electric vehicles (HEVs) have been attracting more and more attention from car manufacturers and researchers. Due to involving two energy sources, i.e., engine and battery, the powertrain in HEVs is a complicated electromechanical coupling system that generates noise and vibration different from that of a traditional vehicle. Accordingly, it is very important to explore the noise and vibration characteristics of HEVs. In this book, a hybrid vehicle with two motors is taken as an example, consisting of a compound planetary gear set (CPGS) as the power-split device, to analyze the noise and vibration characteristics. It is specifically intended for graduates and anyone with an interest in the electrification of full hybrid vehicles. The book begins with the research background and significance of the HEV. The second chapter presents the structural description and working principal of the target hybrid vehicle. Chapter 3 highlights the noise, vibration, and harshness (NVH) tests and corresponding analysis of the hybrid powertrain. Chapter 4 provides transmission system parameters and meshing stiffness calculation. Chapter 5 discusses the mathematical modeling and analyzes torsional vibration (TV) of HEVs. Finally, modeling of the hybrid powertrain with ADAMS is given in Chapter 6.

This modern era has had many names: the golden age, the machine age, the atomic age, the electronic age, and so on. One further title, hitherto unpublicized, it eminently deserves: the age of noise. Man has compounded the natural noise that preceded his existence on the earth until no point on this globe is free from it. Even in the desert's hush, radio waves pervade the air and provide a source of potential noise. The shorter waves escape from the earth and fill interplanetary space with the mingled clamor of FM, TV, radar, and other insistent voices. This book deals with the important problem of radio noise, its sources, whether manmade or natural, over the known range of frequencies. Certain of these contributions will interest the communicator, enabling him to estimate the potential interference from various types of sources. Other contributions deal mainly with scientific problems, such as the origins and significance of certain characteristic noise radiations. The contributors to this book are experts on the various phases of radio noise. The individual chapters derive from papers presented at a Conference on Radio Noise, held at Harvard College Observatory, April 22, 1958.

Planetary Noise: Selected Poetry of Erín Moure gathers four decades of poetry from a celebrated Canadian poet and translator who has persistently reconfigured the linguistic and material relations of English. Moure’s poems and networked sequences are hybrid and often polylingual; they work with contradiction, paradox, and verbal detritus— linguistic hics and blips often too quickly dismissed as noise—to create new conditions for thought and pleasure. From postdramatic theatre to queer and feminist theory, from the politics of citizenship and genocide to the minutiae of digital poetics, from the clamor of love to the shadows of grief and memory, Moure has joyously toppled hierarchies of meaning and parasited dominant discourses to create poetry that crosses borders, embracing hope, not war. This volume, edited by poet and literary scholar Shannon Maguire, also features an extensive introduction to Moure’s poetry, a section of poetry by others translated by Moure, and an afterword on translation by the poet. An online reader’s companion is available at wesleyan.edu/wespress/readerscompanions.

The noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is a critical feature for customers to assess the performance and quality of vehicles. NVH characteristics are higher among factors that customers use to judge the vehicle's quality.This book sets out to introduce the basic concepts, principles, and applications of the NVH development and refi nement of Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Fuel Cell Electric Vehicles. Each type comes with its own set of challenges.

Everyone knows what noise is. Or do they? Can we in fact say that one man's noise is another teenager's music? Is noise in fact only an auditory phenomenon or does it extend far beyond this realm? If our common definitions of noise are necessarily subjective and noise is not just unpleasant sound, then it merits a closer look (or listen). Greg Hainge sets out to define noise in this way, to find within it a series of operations common across its multiple manifestations that allow us to apprehend it as something other than a highly subjective term that tells us very little. Examining a wide range of texts, including Sartre's novel Nausea and David Lynch's iconic films Eraserhead and Inland Empire, Hainge investigates some of the Twentieth Century's most infamous noisemongers to suggest that they're not that noisy after all; and it finds true noise in some surprising places. The result is a thrilling and illuminating study of sound and culture.
