Seismic Imaging and Inversion : Volume 1: Application of Linear Inverse Theory
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.
A major objective of this book is to fill the gap between traditional logic design principles and logic design/optimization techniques used in practice. Over the last two decades several techniques for computer-aided design and optimization of logic circuits have been developed. However, underlying theories of these techniques are inadequately covered or not covered at all in undergraduate text books. This book covers not only the “classical” material found in current text books but also selected materials that modern logic designers need to be familiar with.

Instructors love Numerical Methods for Engineers because it makes teaching easy! Students love it because it is written for them–with clear explanations and examples throughout. The text features a broad array of applications that span all engineering disciplines. The sixth edition retains the successful instructional techniques of earlier editions. Chapra and Canale’s unique approach opens each part of the text with sections called Motivation, Mathematical Background, and Orientation. This prepares the student for upcoming problems in a motivating and engaging manner. Each part closes with an Epilogue containing Trade-Offs, Important Relationships and Formulas, and Advanced Methods and Additional References. Much more than a summary, the Epilogue deepens understanding of what has been learned and provides a peek into more advanced methods. Helpful separate Appendices. “Getting Started with MATLAB” abd “Getting Started with Mathcad” which make excellent references. Numerous new or revised problems drawn from actual engineering practice, many of which are based on exciting new areas such as bioengineering. The expanded breadth of engineering disciplines covered is especially evident in the problems, which now cover such areas as biotechnology and biomedical engineering. Excellent new examples and case studies span asll areas of engineering disciplines; the students using this text will be able to apply their new skills to their chosen field. Users will find use of software packages, specifically MATLAB(R), Excel(R) with VBA and Mathcad(R). This includes material on developing MATLAB(R) m-files and VBA macros.
Pozar’s new edition of Microwave Engineering includes more material on active circuits, noise, nonlinear effects, and wireless systems. Chapters on noise and nonlinear distortion, and active devices have been added along with the coverage of noise and more material on intermodulation distortion and related nonlinear effects. On active devices, there’s more updated material on bipolar junction and field effect transistors.
New and updated material on wireless communications systems, including link budget, link margin, digital modulation methods, and bit error rates is also part of the new edition. Other new material includes a section on transients on transmission lines, the theory of power waves, a discussion of higher order modes and frequency effects for microstrip line, and a discussion of how to determine unloaded.
Social work is the profession that claims to intervene to enhance people’s well-being. However, social workers have played a low-key role in environmental issues that increasingly impact on people’s well-being, both locally and globally.
This compelling new contribution confronts this topic head-on, examining environmental issues from a social work perspective. Lena Dominelli draws attention to the important voice of practitioners working on the ground in the aftermath of environmental disasters, whether these are caused by climate change, industrial accidents or human conflict. The author explores the concept of ‘green social work’ and its role in using environmental crises to address poverty and other forms of structural inequalities, to obtain more equitable allocations of limited natural resources and to tackle global socio-political forces that have a damaging impact upon the quality of life of poor and marginalized populations at local levels. The resolution of these matters is linked to community initiatives that social workers can engage in to ensure that the quality of life of poor people can be enhanced without costing the Earth.
This important book will appeal to those in the fields of social work, social policy, sociology and human geography. It powerfully reveals how environmental issues are an integral part of social work’s remit if it is to retain its currency in the modern world and emphasize its relevance to the social issues that societies have to resolve in the twenty-first century.
