Decomposition

The hidden material histories of music. Music is seen as the most immaterial of the arts, and recorded music as a progress of dematerialization—an evolution from physical discs to invisible digits. In Decomposed, Kyle Devine offers another perspective. He shows that recorded music has always been a significant exploiter of both natural and human resources, and that its reliance on these resources is more problematic today than ever before. Devine uncovers the hidden history of recorded music—what recordings are made of and what happens to them when they are disposed of. Devine's story focuses on three forms of materiality. Before 1950, 78 rpm records were made of shellac, a bug-based resin. Between 1950 and 2000, formats such as LPs, cassettes, and CDs were all made of petroleum-based plastic. Today, recordings exist as data-based audio files. Devine describes the people who harvest and process these materials, from women and children in the Global South to scientists and industrialists in the Global North. He reminds us that vinyl records are oil products, and that the so-called vinyl revival is part of petrocapitalism. The supposed immateriality of music as data is belied by the energy required to power the internet and the devices required to access music online. We tend to think of the recordings we buy as finished products. Devine offers an essential backstory. He reveals how a range of apparently peripheral people and processes are actually central to what music is, how it works, and why it matters.

This book covers the results of investigations into the mechanisms and kinetics of thermal decompositions of solid and liquid substances on the basis of thermochemical analyses. The main features of these reactions are explained and many problems and unusual phenomena, which have accumulated in this field are interpreted. New methods of TA measurement and calculation have been developed, which permit the precision and accuracy of determination of kinetic parameters to be increased substantially.

Decomposition and Isomerization of Organic Compounds

Decomposition is a bracing, revisionary, and provocative inquiry into music—from Beethoven to Duke Ellington, from Conlon Nancarrow to Evelyn Glennie—as a personal and cultural experience: how it is composed, how it is idiosyncratically perceived by critics and reviewers, and why we listen to it the way we do. Andrew Durkin, best known as the leader of the West Coast–based Industrial Jazz Group, is singular for his insistence on asking tough questions about the complexity of our presumptions about music and about listening, especially in the digital age. In this winning and lucid study he explodes the age-old concept of musical composition as the work of individual genius, arguing instead that in both its composition and reception music is fundamentally a collaborative enterprise that comes into being only through mediation. Drawing on a rich variety of examples—Big Jay McNeely’s “Deacon’s Hop,” Biz Markie’s “Alone Again,” George Antheil’s Ballet Mécanique, Frank Zappa’s “While You Were Art,” and Pauline Oliveros’s “Tuning Meditation,” to name only a few—Durkin makes clear that our appreciation of any piece of music is always informed by neuroscientific, psychological, technological, and cultural factors. How we listen to music, he maintains, might have as much power to change it as music might have to change how we listen.

This book offers a comprehensive presentation of some of the most successful and popular domain decomposition preconditioners for finite and spectral element approximations of partial differential equations. It places strong emphasis on both algorithmic and mathematical aspects. It covers in detail important methods such as FETI and balancing Neumann-Neumann methods and algorithms for spectral element methods.

In Colombia, decades of social and armed conflict and the US-led war on drugs have created a seemingly untenable situation for scientists and rural communities as they attempt to care for forests and grow non-illicit crops. In Vital Decomposition Kristina M. Lyons presents an ethnography of human-soil relations. She follows state soil scientists and peasants across labs, greenhouses, forests, and farms and attends to the struggles and collaborations between farmers, agrarian movements, state officials, and scientists over the meanings of peace, productivity, rural development, and sustainability in Colombia. In particular, Lyons examines the practices and philosophies of rural farmers who value the decomposing layers of leaves, which make the soils that sustain life in the Amazon, and shows how the study and stewardship of the soil point to alternative frameworks for living and dying. In outlining the life-making processes that compose and decompose into soil, Lyons theorizes how life can thrive in the face of the violence, criminalization, and poisoning produced by militarized, growth-oriented development.

The factory scheduling problem, that of allocating machines to competing jobs in manufacturing facilities to optimize or at least improve system performance, is encountered in many different manufacturing environments. Given the competitive pressures faced by many companies in today's rapidly changing global markets, improved factory scheduling should contribute to a flrm's success. However, even though an extensive body of research on scheduling models has been in existence for at least the last three decades, most of the techniques currently in use in industry are relatively simplistic, and have not made use of this body of knowledge. In this book we describe a systematic, long-term research effort aimed at developing effective scheduling algorithms for complex manufacturing facilities. We focus on a speciflc industrial context, that of semiconductor manufacturing, and try to combine knowledge of the physical production system with the methods and results of scheduling research to develop effective approximate solution procedures for these problems. The class of methods we suggest, decomposition methods, constitute a broad family of heuristic approaches to large, NP-hard scheduling problems which can be applied in other environments in addition to those studied in this book.
