Information-Based Inversion and Processing with Applications
Information-Based Inversion and Processing with Applications examines different classical and modern aspects of geophysical data processing and inversion with emphasis on the processing of seismic records in applied seismology. Chapter 1 introduces basic concepts including: probability theory (expectation operator and ensemble statistics), elementary principles of parameter estimation, Fourier and z-transform essentials, and issues of orthogonality. In Chapter 2, the linear treatment of time series is provided. Particular attention is paid to Wold decomposition theorem and time series models (AR, MA, and ARMA) and their connection to seismic data analysis problems. Chapter 3 introduces concepts of Information theory and contains a synopsis of those topics that are used throughout the book. Examples are entropy, conditional entropy, Burg's maximum entropy spectral estimator, and mutual information. Chapter 4 provides a description of inverse problems first from a deterministic point of view, then from a probabilistic one. Chapter 5 deals with methods to improve the signal-to-noise ratio of seismic records. Concepts from previous chapters are put in practice for designing prediction error filters for noise attenuation and high-resolution Radon operators. Chapter 6 deals with the topic of deconvolution and the inversion of acoustic impedance. The first part discusses band-limited extrapolation assuming a known wavelet and considers the issue of wavelet estimation. The second part deals with sparse deconvolution using various 'entropy' type norms. Finally, Chapter 7 introduces recent topics of interest to the authors. The emphasis of this book is on applied seismology but researchers in the area of global seismology, and geophysical signal processing and inversion will find material that is relevant to the ubiquitous problem of estimating complex models from a limited number of noisy observations.

An examination of how female same-sex desires were represented in a wide range of Italian and British medical writings, 1870-1920. It shows how the psychiatric category of sexual inversion was positioned alongside other medical ideas of same-sex desires, such as the virago, tribade-prostitute, fiamma and gynaecological explanations.
The Great Inversion and the Future of the American City
Eye-opening and thoroughly engaging, this is an indispensible look at American urban/suburban society and its future. In The Great Inversion, Alan Ehrenhalt, one of our leading urbanologists, reveals how the roles of America's cities and suburbs are changing places--young adults and affluent retirees moving in, while immigrants and the less affluent are moving out--and addresses the implications of these shifts for the future of our society. Ehrenhalt shows us how the commercial canyons of lower Manhattan are becoming residential neighborhoods, and how mass transit has revitalized inner-city communities in Chicago and Brooklyn. He explains why car-dominated cities like Phoenix and Charlotte have sought to build twenty-first-century downtowns from scratch, while sprawling postwar suburbs are seeking to attract young people with their own form of urbanized experience.
Generalised Euler-Jacobi Inversion Formula and Asymptotics beyond All Orders

Generalised Euler-Jacobi Inversion Formula and Asymptotics beyond All Orders

Cambridge University Press
1995
pokkari
This work presents exciting new developments in understanding the subdominant exponential terms of asymptotic expansions which have previously been neglected. By considering special exponential series arising in number theory, the authors derive the generalised Euler-Jacobi series, expressed in terms of hypergeometric series. Dingle’s theory of terminants is then employed to show how the divergences in both dominant and subdominant series of a complete asymptotic expansion can be tamed. Numerical results are used to illustrate that a complete asymptotic expansion can be made to agree with exact results for the generalised Euler-Jacobi series to any desired degree of accuracy. All researchers interested in the fascinating area of exponential asymptotics will find this a most valuable book.

Full Field Inversion Methods in Ocean and Seismo-Acoustics
Recent advances in the power of inversion methods, the accuracy of acoustic field prediction codes, and the speed of digital computers have made the full field inversion of ocean and seismic parameters on a large scale a practical possibility. These methods exploit amplitude and phase information detected on hydrophone/geophone arrays, thereby extending traditional inversion schemes based on time of flight measurements. Full field inversion methods provide environmental information by minimising the mismatch between measured and predicted acoustic fields through a global search of possible environmental parameters. Full Field Inversion Methods in Ocean and Seismo-Acoustics is the formal record of a conference held in Italy in June 1994, sponsored by NATO SACLANT Undersea Research Centre. It includes papers by NATO specialists and others. Topics covered include: · speed and accuracy of acoustic field prediction codes · signal processing strategies · global inversion algorithms · search spaces of environmental parameters · environmental stochastic limitations · special purpose computer architectures · measurement geometries · source and receiving sensor technologies.
Experimental Acoustic Inversion Methods for Exploration of the Shallow Water Environment
In recent years, research on acoustic remote sensing of the ocean has evolved considerably, especially in studying complex physical and biological processes in shallow water environments. To review the state of the art, an international workshop was held at Carvoeiro, Portugal, in March 1999, bringing together leading international researchers in the field. In contrast to much of the recent theoretical work, emphasis was placed on the experimental validation of the techniques. This volume, based on presentations at this workshop, summarizes a range of diverse and innovative applications. The invited contributions explore the use of acoustics to measure bottom properties and morphology, as well as to probe buried objects within the sediment. Within the water column, sound is applied to imaging of oceanographic features such as currents and tides or monitoring of marine life. Another key theme is the use of sound to solve geometric inverse problems for precise tracking of undersea vehicles. Audience: This volume should be useful both to the novice seeking an introduction to the field and to advanced researchers interested in the latest developments in acoustic sensing of the ocean environment. The workshop was sponsored by the Fundação para a Ciêcia e a Tecnologia (Portuguese Foundation for Science and Technology).
The Discourse Function of Inversion in English
First published in 1997. This dissertation presents a discourse-functional account of English inversion, based on an empirical study of natural language data. The central finding is that inversion is subject to a pragmatic constraint on the information status of its constituents; specifically, the information represented by the preposed constituent must be at least as familiar within the discourse as is that represented by the postposed constituent.
Hegel's Inversion of Philosophy

Hegel's Inversion of Philosophy

W.Clark Wolf

Cambridge University Press
2026
sidottu
Hegel's philosophy is often presented as a reconciliation between thought and the world, and thus logic and metaphysics. But what is the basis of this reconciliation? In this book, Clark Wolf argues that the key to Hegel's transformation of philosophy lies in his recognition of the special logical basis of the humanly made world. Human artifacts and institutions are not merely represented by concepts; concepts are necessary for their very existence. For this reason, Hegel sees the human world, the world of spirit or Geist, as more central in philosophy than the mind-independent world of nature. Hegel's philosophy is thus a humanism. Wolf argues that this humanistic conception of philosophy is justified in Hegel's Science of Logic, since its logical basis is his theory of concepts. Through a detailed interpretation of the Doctrine of the Concept, this book sheds new light on Hegelian idealism.

Seismic Imaging and Inversion: Volume 1

Extracting information from seismic data requires knowledge of seismic wave propagation and reflection. The commonly used method involves solving linearly for a reflectivity at every point within the Earth, but this book follows an alternative approach which invokes inverse scattering theory. By developing the theory of seismic imaging from basic principles, the authors relate the different models of seismic propagation, reflection and imaging - thus providing links to reflectivity-based imaging on the one hand and to nonlinear seismic inversion on the other. The comprehensive and physically complete linear imaging foundation developed presents new results at the leading edge of seismic processing for target location and identification. This book serves as a fundamental guide to seismic imaging principles and algorithms and their foundation in inverse scattering theory, and is a valuable resource for working geoscientists, scientific programmers and theoretical physicists.

This second volume of Seismic Imaging and Inversion supersedes the first with direct nonlinear inverse theory – where all the assumptions and shortcomings of the linear theory are removed. Chapters follow the processing sequence, including predicting the reference and scattered wavefields; de-ghosting; removing multiples; Q compensation; depth imaging; and direct non-linear inversion of target mechanical properties. Every step in the processing chain is achieved directly without knowing, estimating, or determining any subsurface information, including a velocity model. No other seismic concept or methodology has that capability. Taken together, the two volumes provide researchers and industry practitioners with a solid understanding of current mainstream methods as well as a new and more capable methodology that reduces to conventional methods when the prerequisites and assumptions within those are satisfied. This provides new options in the seismic toolbox that facilitate target identification across a broader set of seismic offshore and onshore plays.
