Discrete Signals and Inverse Problems Discrete Signals and Inverse Problems examines fundamental concepts necessary to engineers and scientists working with discrete signal processing and inverse problem solving, and places emphasis on the clear understanding of algorithms within the context of application needs. Based on the original ‘Introduction to Discrete Signals and Inverse Problems in Civil Engineering’, this expanded and enriched version: combines discrete signal processing and inverse problem solving in one bookcovers the most versatile tools that are needed to process engineering and scientific datapresents step-by-step ‘implementation procedures’ for the most relevant algorithmsprovides instructive figures, solved examples and insightful exercisesDiscrete Signals and Inverse Problems is essential reading for experimental researchers and practicing engineers in civil, mechanical and electrical engineering, non-destructive testing and instrumentation. This book is also an excellent reference for advanced undergraduate students and graduate students in engineering and science.

J. Carlos Santamarina, Georgia Institute of Technology, USA in collaboration with Katherine A. Klein, University of Toronto, Canada; Moheb A. Fam, Cairo University, Egypt Soils are unique materials. Analogous to all other particulate materials, their properties depend on environmental parameters, such as confinement and fluid characteristics. While their behavior is complex, simple micromechanical analyses at the particle level provide unparalleled insight. Furthermore, elastic and electromagnetic waves can be effectively used to gain complementary information about the particulate medium, leading to unique possibilities for studies in engineering and science, including field applications for site assessment and process monitoring. This book is divided into five parts. The first part dwells on the problem of scale and includes a general introduction to materials. In the second part, the behavior of particulate materials is reviewed, with emphasis on the microscale interpretation of macroscale behavior. Fundamental differences between fine and coarse particulate materials are highlighted. The third and fourth parts center on the propagation of mechanical and electromagnetic waves in particulate materials, addressing phenomena such as stiffness, polarization and losses. These two units include laboratory techniques to measure the elastic and electromagnetic spectral response of particulate materials, and an extensive compilation of experimental data. Finally, the fifth part applies elastic and electromagnetic waves to monitoring process in soils. Emphasis is placed on clear, simple analyses and explanations of complex physical phenomena, making this book ideal for self-study. Furthermore, no other book provides such an in-depth description of soils and their behavior and the interaction of elastic and electromagnetic waves and particulate materials (including material data and experimental methods). Thus, this is an invaluable reference for postgraduates, research scientists and practitioners in geotechnical, civil and environmental engineering, as well as scientists in related areas such as physics, geophysics and materials science.

Experimental Research: Brief Essays on Timeless Concepts offers a unique exploration of the experimental process that transcends disciplinary boundaries and technological trends. Through a series of concise, thought-provoking essays, the book distills enduring principles of scientific inquiry. Addressing foundational topics from measurement and dimensional analysis to cognitive factors in research and technical communication, it cultivates a deep, reflective understanding of experimentation as both an intellectual craft and a scientific discipline.Organized into seven thematic chapters, the essays delve into topics rarely addressed in conventional manuals, including the epistemology of experimentation, creative thinking in research, principles of device design and the thoughtful integration of modern tools into contemporary experimental work. Rather than focusing on discipline-specific techniques, the authors emphasize universal aspects of experimentation that cut across fields, blending conceptual insight with practical relevance and historical perspective. The result is a timeless perspective on experimental methods that balances accessibility with intellectual rigor.This volume is an essential resource for young scholars learning to design, conduct and interpret experiments independently, such as graduate students, postdoctoral researchers and early-career faculty who, despite solid technical backgrounds, have received little formal guidance in the conceptual and cognitive aspects of experimentation. For educators and established researchers, it offers fresh perspectives on mentoring the next generation of experimentalists in an era of rapid technological change.
