Seismic inversion aims to reconstruct a quantitative model of the Earth subsurface, by solving an inverse problem based on seismic measurements. There are at least three fundamental issues to be solved simultaneously: non-linearity, non-uniqueness, and instability. This book covers the basic theory and techniques used in seismic inversion, corresponding to these three issues, emphasising the physical interpretation of theoretical concepts and practical solutions. This book is written for master and doctoral students who need to understand the mathematical tools and the engineering aspects of the inverse problem needed to obtain geophysically meaningful solutions. Building on the basic theory of linear inverse problems, the methodologies of seismic inversion are explained in detail, including ray-impedance inversion and waveform tomography etc. The application methodologies are categorised into convolutional and wave-equation based groups. This systematic presentation simplifies the subject and enables an in-depth understanding of seismic inversion. This book also provides a practical guide to reservoir geophysicists who are attempting quantitative reservoir characterisation based on seismic data. Philosophically, the seismic inverse problem allows for a range of possible solutions, but the techniques described herein enable geophysicists to exclude models that cannot satisfy the available data. This book summarises the author’s extensive experience in both industry and academia and includes innovative techniques not previously published.
Collecting short thought pieces by some of the leading thinkers on the emerging 'Immersive Internet', Power and Teigland's book questions what a more immersive and intimate internet – based on social media, augmented reality, virtual worlds, online games, 3D internet and beyond – might mean for society and for each of us.
This diverse collection of essays and testimonies challenges critical orthodoxies about the twenty-first century boom in immersive theatre and performance. A culturally and institutionally eclectic range of producers and critics comprehensively reconsider the term ‘immersive’ and the practices it has been used to describe. Applying ecological, phenomenological and political ideas to both renowned and lesser-known performances, contributing scholars and artists offers fresh ideas on the ethics and practicalities of participatory performance. These ideas interrogate claims that have frequently been made by producers and by critics that participatory performance extends engagement. These claims are interrogated across nine dimensions of engagement: bodily, technological, spatial, temporal, spiritual, performative, pedagogical, textual, social. Enquiry is focussed along the following seams of analysis: the participant as co-designer; the challenges facing the facilitator of immersive/participatory performance; the challenges facing the critic of immersive/participatory performance; how and why immersion troubles boundaries between the material and the magical.

Sexual Inversion was the first English medical textbook about homosexuality. It had a chequered publishing history, going through five editions between 1896 and 1915. This edition, with a long critical introduction, places the book in its intellectual and social contexts, and considers the historiography surrounding this important work.

Immersive theatre currently enjoys ubiquity, popularity and recognition in theatre journalism and scholarship. However, the politics of immersive theatre aesthetics still lacks a substantial critique. Does immersive theatre model a particular kind of politics, or a particular kind of audience? What’s involved in the production and consumption of immersive theatre aesthetics? Is a productive audience always an empowered audience? And do the terms of an audience’s empowerment stand up to political scrutiny? Beyond Immersive Theatre contextualises these questions by tracing the evolution of neoliberal politics and the experience economy over the past four decades. Through detailed critical analyses of work by Ray Lee, Lundahl & Seitl, Punchdrunk, shunt, Theatre Delicatessen and Half Cut, Adam Alston argues that there is a tacit politics to immersive theatre aesthetics – a tacit politics that is illuminated by neoliberalism, and that is ripe to be challenged by the evolution and diversification of immersive theatre.
In the politically fluid landscape of modern America, Kurt Vonnegut offers his readers a mirror of cultural self-reflection. Through his personal experiences, he encourages his readers to acknowledge their perceptions of society and ideology as illusionary, allowing them the freedom to recreate a better world. Vonnegut’s novels are as relevant today as they were in post-war America, a call for people to allow America to become a beacon of humanity, the role it was always meant to fulfill. This book focuses on Kurt Vonnegut’s novels Player Piano, Cat’s Cradle, and Slaughterhouse-Five, exploring the themes of technology, religion, and war through the literary theories of Mikhail Bakhtin. It concentrates on Bakhtin’s carnivalesque inversion from Rabelais and His World and his theoretical perspectives on the text as a site of struggle from The Dialogic Imagination. “Emma Saggers’ far-reaching application of Bakhtin’s theories of the Carnivalesque to the fiction of Kurt Vonnegut is an astute realisation of the possibilities of both. Using the theory as an illuminating lens while keeping the fiction front and centre, Vonnegut’s work is given the kind of sophisticated, incisive attention it deserves but does not always get. Now more than ever, we need the insights and deep humanity of Vonnegut, and Emma Saggers’ study is an ideal critical accompaniment to reading and rereading this much-loved but still under-appreciated American writer.”—Owen Robinson, Senior Lecturer, Department of Literature Film and Theatre Studies, University of Essex, United Kingdom
Harish-Chandra's general Plancherel inversion theorem admits a much shorter presentation for spherical functions. The authors have taken into account contributions by Helgason, Gangolli, Rosenberg, and Anker from the mid-1960s to 1990. Anker's simplification of spherical inversion on the Harish-Chandra Schwartz space had not yet made it into a book exposition. Previous expositions have dealt with a general, wide class of Lie groups. This has made access to the subject difficult for outsiders, who may wish to connect some aspects with several if not all other parts of mathematics, and do so in specific cases of intrinsic interest. The essential features of Harish-Chandra theory are exhibited on SLn(R), but hundreds of pages of background can be replaced by short direct verifications. The material becomes accessible to graduate students with especially no background in Lie groups and representation theory. Spherical inversion is sufficient to deal with the heat kernel, which is at the center of the authors' current research. The book will serve as a self-contained background for parts of this research.
Relying on a wealth of new data, this book argues that long-standing puzzles of Negative Inversion (NI) syntax are not puzzles at all when viewed through the lenses of Gricean pragmatics and Labovian sociolinguistics. Focusing on sentences such as "Can't nobody lift that rock" in African American, Anglo, and Chicano Englishes in Texas, the book provides tidy solutions to problems such as: the NI’s relationship to its non-inverted counterpart, its relationship to existential “there” sentences, to modal existential sentences, to the definiteness effects surrounding its NP subject, the emphatic meaning with which it seems to be associated, and more. The book argues that such issues, which have been explored in the syntax and semantics literature since the late 1960s, are handled more fruitfully via Gricean reasoning, demographics of use, and a simple semantics. As such, the book argues that NI can be freed from the “syntactico-semantic straitjacket” into which it has often been forced. It also demonstrates ways in which pragmatic and sociolinguistic thought can be brought together to inform larger linguistic analyses.
The first book in the Skolian Empire saga by the Nebula Award–winning author. “Fast, smart, speculative . . . another stellar debut.” —Los Angeles Daily News Soz Valdoria, a bioengineered fighter pilot—and first in line for the military command of her people—has found refuge with her squad on the sanctuary planet of Delos. It offers a respite from the war that rages between her Skolian people and their enemies, the Traders. Looking for rest and relaxation, they must still be on their guard for the Trader soldiers who also visit the sanctuary. In a bar, they confront the worst of the worst: an Aristo from the Trader ruling caste, seemingly on the prowl for a “provider” he can use for his barbaric impulses. His presence takes Soz back to her days as a prisoner of war, when she became the plaything of a sadistic and soulless Aristo. And yet something is off about this Aristo. Unable to ignore her instincts, Soz searches the city until she finds him in a secured mansion. Breaching its fortifications and eluding its guards, she discovers a devastating truth: this man is no true Aristo. He is a genetic anomaly like Soz, one of the few people who can handle the massive neurological demands of the psibernet, the technological marvel that gives the Skolians their only advantage over the Traders. This false Aristo, this sheep in a wolf’s clothing, is heir to the Trader throne. The emperor created him for one reason—to take control of the Skolian network and conquer Soz’s people. But Soz has never felt such a connection as she does to this Trader heir. It may prove her—and the universe’s—undoing . . . “This is one of the best SF first novels in years.” —Booklist

This is a new edition of "Sexual Inversion," originally published in 1915 by F. A. Davis Company, Publishers, of Philadelphia. Part of the project Immortal Literature Series of classic literature, this is a new edition of the classic work published in 1915-not a facsimile reprint. Obvious typographical errors have been carefully corrected and the entire text has been reset and redesigned by Pen House Editions to enhance readability, while respecting the original edition. "Sexual Inversion" was the first English medical textbook on the topic of homosexuality. The book became a part of Ellis's six-volume "Studies in the Psychology of Sex." Havelock Ellis and John Addington Symonds agreed to collaborate on a new study that would combine Symonds's historical analysis on homosexuality with Ellis's experience with medical and scientific theory. Symonds died in 1893 before the book was concluded. "Sexual Inversion" was first published in German in 1896 (Leipzig, by Georg H. Wigand's Verlag) entitled "Das Kontr re Geschlechtsgef hl," under Havelock Ellis and John Addington Symonds. Ellis further revised the text and edited several of Symonds's contributions, with almost every page being rewritten or enlarged. This is the third edition. About the Author: Born in Surrey, England, in 1859, Havelock Ellis was considered by the overwhelming majority of critics as the best translator of "Germinal," mile Zola s masterpiece. Ellis was a social activist, a physician and a psychologist, whose best-known works concern sexuality and criminology. In 1890 he published "The Criminal," a remarkable work on criminal anthropology; in the same year he wrote "The New Spirit," a collection of literary essays on Diderot, Heine, Whitman, Ibsen, and Tolstoi, and Ellis's attempt to synthesize science and religious mysticism; and in 1898 he wrote "Affirmations," which contains essays on Nietzsche, Casanova, Zola, Huysmans, and St. Francis. In 1897, he published "Sexual Inversion," the first medical text in English about homosexuality, which he had co-authored with John Addington Symonds (see short bio below) in an earlier edition, and which became a part of Ellis's six-volume "Studies in the Psychology of Sex." Havelock Ellis died in Suffolk, England, in 1939. About John Addington Symonds: John Addington Symonds was born in Bristol, England, in 1840. He was an English poet, an author of several works, and a literary critic. In 1873 he wrote "A Problem in Greek Ethics" (also published in the Immortal Literature Series), which discussed homosexuality between men. He printed ten copies in 1883, before effectively publishing the book in 1901. He was also known for his work on the Renaissance, as well as for his translations and biographies. He wrote "Our Life in the Swiss Highlands" (1891), biographies of Philip Sidney (1886), Ben Jonson (1886) and Michelangelo (1893), several volumes of poetry and essays, and a translation of the "Autobiography of Benvenuto Cellini" (1887). John Addington Symonds died in Rome in 1893. In 1896, Havelock Ellis published, in German, prepared with the collaboration of Dr. Hans Kurella, "Das kontr re Geschlechtsgef hl" (Leipzig, by Georg H. Wigand's Verlag), later revised and published by Ellis as Sexual Inversion-the first medical text in English about homosexuality, which he had co-authored with Symonds, and which would become a part of Ellis's six-volume "Studies in the Psychology of Sex."
Seismic inversion is now commonly used on post-stack and pre-stack seismic data for estimating rock properties used in reservoir characterization. While seismic migration is aimed at imaging the reflectors or the interfaces at their correct subsurface locations, seismic inversion attempts to estimate elastic and flow properties of the layers bounded by these interfaces. Seismic data are sensitive essentially to seismic wave velocity and density contrasts in the subsurface rocks. Because of significant overlap in elastic properties among different rock types, mapping of these elastic properties to rock types and estimating porosity are not trivial. Thus, seismic inversion is best done by combining data of all types such as seismic, well log, petrophysics, and production history. The results of seismic inversion can be best interpreted by a team of geologists, geophysicists, and reservoir engineers. This book explains the fundamental principles of seismic exploration, seismic wave propagation, and inversion in a language that is understandable by geoscientists and engineers alike so that the team is aware of the significance and limitations of the inversion results.
Describes the theory and practice of inverting seismic data for subsurface rock properties of the earth. The primary application is for inverting reflection and transmission data from engineering or exploration surveys, but methods also can be used for earthquake studies. Computational labs are provided for most chapters.
