A practical and insightful discussion of time-frequency analysis methods and technologies Time-frequency analysis of seismic signals aims to reveal the local properties of nonstationary signals. The local properties, such as time-period, frequency, and spectral content, vary with time, and the time of a seismic signal is a proxy of geologic depth. Therefore, the time-frequency spectrum is composed of the frequency spectra that are generated by using the classic Fourier transform at different time positions. Different time-frequency analysis methods are distinguished in the construction of the local kernel prior to using the Fourier transform. Based on the difference in constructing the Fourier transform kernel, this book categorises time-frequency analysis methods into two groups: Gabor transform-type methods and energy density distribution methods. This book systematically presents time-frequency analysis methods, including technologies which have not been previously discussed in print or in which the author has been instrumental in developing. In the presentation of each method, the fundamental theory and mathematical concepts are summarised, with an emphasis on the engineering aspects. This book also provides a practical guide to geophysicists who attempt to generate geophysically meaningful time-frequency spectra, who attempt to process seismic data with time-dependent operations for the fidelity of nonstationary signals, and who attempt to exploit the time-frequency space seismic attributes for quantitative characterisation of hydrocarbon reservoirs.

Contemporary spinal surgeons, whether orthopedic or neurosurgeons, are increasingly recognizing minimally invasive spine surgery (MISS) as a valuable option for managing advanced degenerative diseases. MISS techniques minimize blood loss and surgical site pain, while speeding recovery. Thus, the combination of MISS with adult spinal deformity was a natural choice. Currently, the techniques, technologies, and education of surgeons have finally reached a point where MISS deformity surgeries are becoming commonplace. Nevertheless, the field is young enough (and still evolving) that no comprehensive texts have addressed the unique challenges it poses for surgeons. This book fills that gap.

Owing to the developments and applications of computer science, ma thematicians began to take a serious interest in the applications of number theory to numerical analysis about twenty years ago. The progress achieved has been both important practically as well as satisfactory from the theoretical view point. It'or example, from the seventeenth century till now, a great deal of effort was made in developing methods for approximating single integrals and there were only a few works on multiple quadrature until the 1950's. But in the past twenty years, a number of new methods have been devised of which the number theoretic method is an effective one. The number theoretic method may be described as follows. We use num ber theory to construct a sequence of uniformly distributed sets in the s dimensional unit cube G , where s ~ 2. Then we use the sequence to s reduce a difficult analytic problem to an arithmetic problem which may be calculated by computer. For example, we may use the arithmetic mean of the values of integrand in a given uniformly distributed set of G to ap s proximate the definite integral over G such that the principal order of the s error term is shown to be of the best possible kind, if the integrand satis fies certain conditions.

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.

High-pressure mineral physics is a field that is strongly driven by the development of new technology. Fifty years ago, when experimentally achievable pressures were limited to just 25 GPa, little was know about the mineralogy of the Earth's lower mantle. Silicate perovskite, the likely dominant mineral of the deep Earth, was identified only when the high-pressure techniques broke the pressure barrier of 25 GPa in 1970s. However, as the maximum achievable pressure reached beyond one Megabar (100 GPa) and even to the pressure of Earth's core on minute samples, new discoveries increasingly were fostered by the development of new analytical techniques and improvements in sensitivity and precision of existing techniques.

The book consists of six sections which group the papers according to their main topics: a) Elastic and Anelastic Properties; b) Rheology; c) Melt and Glass Properties; d) Structural and Magnetic Properties; e) Diffraction and Spectroscopy; f) Pressure Calibration and Generation. As many papers cover multiple topics, readers may find papers of interest in different sections. All papers are prepared with emphasis on technical details suitable for a technical reference.

Speaking about Chinese writing entails thinking about how writing speaks through various media. In the guises of the written character and its imprints, traces, or ruins, writing is more than textuality. The goal of this volume is to consider the relationship of writing to materiality in China's literary history and to ponder the physical aspects of the production and circulation of writing. To speak of the thing-ness of writing is to understand it as a thing in constant motion, transported from one place or time to another, one genre or medium to another, one person or public to another.

Thinking about writing as the material product of a culture shifts the emphasis from the author as the creator and ultimate arbiter of a text's meaning to the editors, publishers, collectors, and readers through whose hands a text is reshaped, disseminated, and given new meanings. By yoking writing and materiality, the contributors to this volume aim to bypass the tendency to oppose form and content, words and things, documents and artifacts, to rethink key issues in the interpretation of Chinese literary and visual culture.

This book is a comprehensive guide to the application of recently introduced and emerging technologies in minimally invasive spine surgery (MISS). These technologies, including 2D and 3D navigation, endoscopy, virtual and augmented reality, robotics, and 3D printing, are helping to overcome previous limitations of MISS, such as the steep learning curve and the need for a great deal of experience in order to achieve optimal outcomes. Compared with traditional techniques, their use is designed to reduce local operative tissue damage, alleviate systemic surgical stress, and enable earlier return to function. The book provides detailed and extensively illustrated accounts of the role of the new technologies and techniques in a wide range of indications. In essence, all spine conditions, whether degenerative, traumatic, or oncologic, will in the near future be amenable to MISS using these approaches. The book will be a source of insight and practical assistance for all surgeons who perform MISS, regardless of their level of experience.
