Following the breakthrough in the last decade in identifying the key parameters for time and depth imaging in anisotropic media and developing practical methodologies for estimating them from seismic data, Seismic Signatures and Analysis of Reflection Data in Anisotropic Media primarily focuses on the far reaching exploration benefits of anisotropic processing. This volume provides the first comprehensive description of reflection seismic signatures and processing methods in anisotropic media. It identifies the key parameters for time and depth imaging in transversely isotropic media and describes practical methodologies for estimating them from seismic data. Also, it contains a thorough discussion of the important issues of uniqueness and stability of seismic velocity analysis in the presence of anisotropy. The book contains a complete description of anisotropic imaging methods, from the theoretical background to algorithms to implementation issues. Numerous applications to synthetic and field data illustrate the improvements achieved by the anisotropic processing and the possibility of using the estimated anisotropic parameters in lithology discrimination. Focuses on the far reaching exploration benefits of anisotropic processing First comprehensive description of reflection seismic signatures and processing methods in anisotropic media

Observing offset-dependent seismic reflectivity has proven to be a valuable exploration tool for the direct detection of hydrocarbons. This monograph provides a comprehensive review of reflection coefficients and their approximations in isotropic media, followed by an in-depth discussion of reflection amplitudes in anisotropic media. No prior knowledge of seismic anisotropy is assumed, and considerable effort is spent to introduce wave propagation and medium parameterizations useful for surface seismic applications in the presence of anisotropy. The first anisotropic model discussed is transverse isotropy with a vertical axis of symmetry (VTI media), typically used to describe shale sequences. Then the study of VTI reflection coefficients is extended to transverse isotropy with a horizontal axis of symmetry (HTI) - the symmetry system that describes a system of parallel vertical cracks. Analysis of the "Shuey-type" approximate HTI P-wave reflection coefficient makes it possible to devise fracture-detection algorithms based on the inversion of azimuthal differences of the P-wave AVO gradient. The monograph also presents analysis of shear- and converted-wave reflection coefficients for HTI and orthorhombic models, discusses practical aspects of applying the azimuthal AVO analysis, and mentions promising recent results.

Provides essential background on anisotropic wave propagation, introduces efficient notation for transversely isotropic (TI) and orthorhombic media, and identifies the key anisotropy parameters for imaging and amplitude analysis. Particular attention is given to moveout analysis and P-wave time-domain processing for VTI and TTI.

This book constitutes the refereed proceedings of the Second International Conference on Meta-Level Architectures and Reflection, Reflection'99, held in St. Malo, France in July 1999. The 13 revised full papers presented were carefully selected from 44 submissions. Also included are six short papers and the abstracts of three invited talks. The papers are organized in sections on programming languages, meta object protocols, middleware/multi-media, work in progress, applications, and meta-programming. The volume covers all current issues arising in the design and analysis of reflective systems and demontrates their practical applications.

Reflection in writing studies is now entering a third generation. Dating from the 1970s, the first generation of reflection focused on identifying and describing internal cognitive processes assumed to be part of composing. The second generation, operating in both classroom and assessment scenes in the 1990s, developed mechanisms for externalizing reflection, making it visible and thus explicitly available to help writers. Now, a third generation of work in reflection is emerging. As mapped by the contributors to A Rhetoric of Reflection, this iteration of research and practice is taking up new questions in new sites of activity and with new theories. It comprises attention to transfer of writing knowledge and practice, teaching and assessment, portfolios, linguistic and cultural difference, and various media, including print and digital. It conceptualizes conversation as a primary reflective medium, both inside and outside the classroom and for individuals and collectives, and articulates the role that different genres play in hosting reflection. Perhaps most important in the work of this third generation is the identification and increasing appreciation of the epistemic value of reflection, of its ability to help make new meanings, and of its rhetorical power—for both scholars and students.

This book is aimed to make careful analysis to various mathematical problems derived from shock reflection by using the theory of partial differential equations. The occurrence, propagation and reflection of shock waves are important phenomena in fluid dynamics. Comparing the plenty of studies of physical experiments and numerical simulations on this subject, this book makes main efforts to develop the related theory of mathematical analysis, which is rather incomplete so far. The book first introduces some basic knowledge on the system of compressible flow and shock waves, then presents the concept of shock polar and its properties, particularly the properties of the shock polar for potential flow equation, which are first systematically presented and proved in this book. Mathematical analysis of regular reflection and Mach reflection in steady and unsteady flow are the most essential parts of this book. To give challenges in future research, some long-standing open problems are listed in the end. This book is attractive to researchers in the fields of partial differential equations, system of conservation laws, fluid dynamics, and shock theory.

Looks at the transformation of government policy since 1980 that has lead to changes in electronic media. The author argues that Washington policymakers must scrap the old regulatory system and write a new policy script designed to guarantee a broadcast service that is free, and dedicated to serving Americans as citizens, not just as consumers.
