First published in 1977, Ronald Johnson's RADI OS revises the first four books of Paradise Lost by excising words, discovering a modern and visionary poem within the seventeenth-century text. As the author explains, "To etch is 'to cut away, ' and each page, as in Blake's concept of a book, is a single picture." With God and Satan crossed out, RADI OS reduces Milton's Baroque poem to elemental forces. In this retelling of the Fall, song precipitates from chaos, sight from fire: "in the shape / as of / above the / rose / through / rose / rising / the radiant sun. -- Contracubierta.

Table radios made primarily of brightly colored plastics represent a relative newcomer to the radio collecting arena. These icons of American industrial design and popular culture were once plentiful, and today they can be found at flea markets, garage and house sales. With more than 430 color photo plus advertisements and black and white vintage photos, this pioneering book is a must for anyone interested in radios, mid-century industrial design, or popular culture.

The Unsignificant: Three Talks on Poetry and Pictures is a selection of lectures that poet and Griffin Award–finalist Srikanth Reddy presented for the Bagley Wright Lecture Series in 2015. True to its title, The Unsignificant is concerned with what it’s not about—not the logical proofs of philosophy but the affective flux of poetry. The lectures approach poetry from Homer to Gertrude Stein to Ronald Johnson obliquely, refracted through images such as Brueghel’s “Landscape with Fall of Icarus,” Hermann Rorschach’s inkblots, or Galileo’s drawings of the moon. Ranging from pictorial backgrounds in visual art to portraiture and similes to the poetics of wonder, The Unsignificant embarks on an unsystematic, errant, and eccentric tour of Western poetry and poetics from the ancient world to our continuous present.

Make Great Stuff! TAB, an imprint of McGraw-Hill Professional, is a leading publisher of DIY technology books for makers, hackers, and electronics hobbyists.

This book examines signal processing techniques for cognitive radios. The book is divided into three parts: Part I, is an introduction to cognitive radios and presents a history of the cognitive radio (CR), and introduce their architecture, functionalities, ideal aspects, hardware platforms, and state-of-the-art developments. Dr. Jayaweera also introduces the specific type of CR that has gained the most research attention in recent years: the CR for Dynamic Spectrum Access (DSA). Part II of the book, Theoretical Foundations, guides the reader from classical to modern theories on statistical signal processing and inference. The author addresses detection and estimation theory, power spectrum estimation, classification, adaptive algorithms (machine learning), and inference and decision processes. Applications to the signal processing, inference and learning problems encountered in cognitive radios are interspersed throughout with concrete and accessible examples. Part III of the book, Signal Processing in Radios, identifies the key signal processing, inference, and learning tasks to be performed by wideband autonomous cognitive radios. The author provides signal processing solutions to each task by relating the tasks to materials covered in Part II. Specialized chapters then discuss specific signal processing algorithms required for DSA and DSS cognitive radios.
