“A brilliant and beautiful meditation on the nature of our attachment to things. Reading Clutter made me long for a life without clutter.” —Malcolm Gladwell, New York Times–bestselling author and host of the Revisionist History podcast “I’m sitting on the floor in my mother’s house, surrounded by stuff.” So begins Jennifer Howard’s Clutter, an expansive assessment of our relationship to the things that share and shape our lives. Sparked by the painful two-year process of cleaning out her mother’s house in the wake of a devastating physical and emotional collapse, Howard sets her own personal struggle with clutter against a meticulously researched history of just how the developed world came to drown in material goods. With sharp prose and an eye for telling detail, she connects the dots between the Industrial Revolution, the Sears & Roebuck catalog, and the Container Store, and shines unsparing light on clutter’s darker connections to environmental devastation and hoarding disorder. In a confounding age when Amazon can deliver anything at the click of a mouse and decluttering guru Marie Kondo can become a reality TV star, Howard’s bracing analysis has never been timelier. “In her stern and wide-ranging new manifesto, Clutter: An Untidy History, journalist Jennifer Howard takes the anti-clutter message a step further. Howard argues that decluttering is not just a personally liberating ritual, but a moral imperative, a duty we owe both to our children and to the planet.” —Jennifer Reese, The Washington Post “Blending her personal experience and her research, Howard creates an engaging narrative that is colored by her investment in understanding hoarding in all of its complexities.” —Linda Levitt, PopMatters
Introduction to RF Propagation
An introduction to RF propagation that spans all wireless applications This book provides readers with a solid understanding of the concepts involved in the propagation of electromagnetic waves and of the commonly used modeling techniques. While many books cover RF propagation, most are geared to cellular telephone systems and, therefore, are limited in scope. This title is comprehensive-it treats the growing number of wireless applications that range well beyond the mobile telecommunications industry, including radar and satellite communications. The author's straightforward, clear style makes it easy for readers to gain the necessary background in electromagnetics, communication theory, and probability, so they can advance to propagation models for near-earth, indoor, and earth-space propagation. Critical topics that readers would otherwise have to search a number of resources to find are included: * RF safety chapter provides a concise presentation of FCC recommendations, including application examples, and prepares readers to work with real-world propagating systems * Antenna chapter provides an introduction to a wide variety of antennas and techniques for antenna analysis, including a detailed treatment of antenna polarization and axial ratio; the chapter contains a set of curves that permit readers to estimate polarization loss due to axial ratio mismatch between transmitting and receiving antennas without performing detailed calculations * Atmospheric effects chapter provides curves of typical atmospheric loss, so that expected loss can be determined easily * Rain attenuation chapter features a summary of how to apply the ITU and Crane rain models * Satellite communication chapter provides the details of earth-space propagation analysis including rain attenuation, atmospheric absorption, path length determination and noise temperature determination Examples of widely used models provide all the details and information needed to allow readers to apply the models with confidence. References, provided throughout the book, enable readers to explore particular topics in greater depth. Additionally, an accompanying Wiley ftp site provides supporting MathCad files for select figures in the book. With its emphasis on fundamentals, detailed examples, and comprehensive coverage of models and applications, this is an excellent text for upper-level undergraduate or graduate students, or for the practicing engineer who needs to develop an understanding of propagation phenomena.
Principles of Space-Time Adaptive Processing
This book presents a systematic introduction to airborne MTI (moving target indication) system design for use in the fields of earth observation, surveillance and reconnaissance, with particular regard to the suppression of clutter returns. New developments in the field and special aspects of airborne MTI radar are also covered.
