Fourier transforms and waves: in four lectures / Преобразование Фурье и волны: в 4-х лекциях

When earth material properties are constant in any of the cartesian variables then it is useful to Fourier transform (FT) that variable.
In seismology, the earth does not change with time (the ocean does!) so for the earth, we can generally gain by Fourier transforming the time axis thereby converting time-dependent differential equations (hard) to algebraic equations (easier) in frequency (temporal frequency).
In seismology, the earth generally changes rather strongly with depth, so we cannot usefully Fourier transform the depth axis and we are stuck with differential equations in . On the other hand, we can model a layered earth where each layer has material properties that are constant in . Then we get analytic solutions in layers and we need to patch them together. <...>

Fourier transforms in radar and signal processing / Преобразования Фурье в радиолокации и обработке сигналов

The basic material for this book has been accumulated from time to time over the author’s working lifetime of about 40 years. The rules-and-pairs approach to Fourier transforms has been employed with good effect in a wide variety of problems, from pulse Doppler radar spectra to delay compensation, and antenna array patterns to efficient clutter simulation. It has been found generally easy and effective, quickly yielding useful results and allowing the user to see clearly the relationships between functions and transforms, waveforms and spectra, rather than losing sight of these in the complexities of integration. It seemed that the benefits of this approach should be better known, and the initial intention was to produce a technical note for use by the author’s colleagues and successors. However, the interest shown and encouragement given by Artech House have been gratefully received, and the opportunity to publicize the technique more widely has been taken.
The support of Roke Manor Research in providing the facilities and freedom to write this book is gratefully acknowledged, as are the backing of C. J. Tarran and the reviewing of S. H. W. Simpson. The final acknowledgment is to the publisher’s reviewer, remaining anonymous, who provided encouragement and useful comments.

Fourier Transforms in Spectroscopy / Преобразования Фурье в спектроскопии

How much should a good spectroscopist know about Fourier transforms? How well should a professional who uses them as a tool in his/her work understand their behavior? Our belief is, that a profound insight of the characteristics of Fourier transforms is essential for their successful use, as a superficial knowledge may easily lead to mistakes and misinterpretations. But the more the professional knows about Fourier transforms, the better he/she can apply all those versatile possibilities offered by them. <...>

Fractals and chaos in geology and geophysics / Фракталы и хаос в геологии и геофизике

The scale invariance of geological phenomena is one of the first concepts taught to a student of geology. It is pointed out that an object that defines the scale, i.e., a coin, a rock hammer, a person, must be included whenever a photograph of a geological feature is taken. Without the scale it is often impossible to determine whether the photograph covers 10 cm or 10 km. For example, self-similar folds occur over this range of scales.

Fracture and in-situ stress characterization of hydrocarbon reservoirs / Разломы и напряженные свойства массива в УВ-коллекторах

Fracture and in-situ stress characterization is fast-evolving as an essential part of characterizing hydrocarbon reserviors. In this book, the Geological Society presents a selection of sixteen chapters that demonstrate the tools, methods, analysis, interpretation and application of this subject. These are of great interest to researchers and scientists in the industry and academia. This chapter includes definitions pertinent to the subject of the book and gives an overview of the papers, classified into seven major themes according to the nature of the studies.

Fractures, fluid flow and mineralization / Трещины, движение флюидов и минерализация

Prior to Hubbert and Rubey's classic paper (Hubbert & Rubey 1959), which specifically recognized the role of high fluid pressures in
lowering the shear stress required to move and emplace large thrust sheets, geologists had tended to ignore the importance of fluids in crustal deformation (Fyfe et al. 1978). Much has changed in the intervening 40 years. It is now accepted that not only do fluids enable deformation but that the converse is also true, i.e. that faulting can cause fluid migration.

From crust to core. A chronicle of deep carbon science / От коры до ядра. Хроника изучения глубинного углерода

Carbon plays a fundamental role on Earth. It forms the chemical backbone for all essential organic molecules produced by living organisms. Carbon-based fuels supply most of society’s energy, and atmospheric carbon dioxide has a huge impact on Earth’s climate. This book provides a complete history of the emergence and development of the new interdisciplinary field of deep carbon science. It traces four centuries of history during which the inner workings of the dynamic Earth were discovered, and it documents the extraordinary scientific revolutions that changed our understanding of carbon on Earth forever: carbon’s origin in exploding stars; the discovery of the internal heat source driving the Earth’s carbon cycle; and the tectonic revolution. Written with an engaging narrative style and covering the scientific endeavors of about 150 pioneers of deep geoscience, this is a fascinating book for students and researchers working in Earth system science and deep carbon research.

From geometry to dynamics of microstructure: using boundary lengths to quantify boundary misorientations and anisotropy

The microstructure of a quartzite experimentally deformed and partially recrystallised at 900 °C, 1.2 GPa confining pressure and strain rate 10~ /s was investigated using orientation contrast and electron backscatter diffraction (EBSD). Boundaries between misoriented domains (grains or subgrains) were determined by image analysis of orientation contrast images. In each domain, EBSD measurements gave the complete quartz lattice orientation and enabled calculation of misorientation angles across every domain boundary. Results are analysed in terms of the boundary density, which for any range of misorientations is the boundary length for that range divided by image area. This allows a more direct comparison of misorientation statistics between different parts of a sample than does a treatment in terms of boundary number.
