This greatly expanded, co-authored, two-volume text provides a comprehensive introduction and explanation of both the theory and practice of modern antenna measurements, from their most basic postulates and assumptions, to the intricate details of their applications in various demanding modern measurement scenarios. Starting with an initial examination of the properties of antennas that allow them to enhance the free-space interaction of electronic systems, the authors then introduce direct far-field and indirect far-field forms of antenna measurements and their various implementations. Detailed descriptions are given of the direct far-field measurement technique CATR (Compact Antenna Test Ranges), Body-Centric measurements, and detailed developments of standard planar, cylindrical, spherical and non-canonical near-field techniques; and includes a through treatment of near-field range error budgets which are an indispensable part of antenna metrology. The books conclude with recent advances in measurement techniques such as aperture diagnostics, phase-less antenna metrology, error correction, and range multi-path suppression techniques. Extensive examples illustrate the concepts and techniques covered. This second edition is thoroughly expanded and now includes new chapters on near-field to far-field transforms from non-canonical surfaces, electromagnetic modelling of CATRs and near-field antenna measurement systems. In addition, there is an expanded chapter on coordinate systems, polarization basis and antenna pattern plotting and new sections on more specialized topics such as 5G and Radome measurements.

'Audio Obscura is more hypnotic than it first sounds - these muttered confessions might even make you miss your train...' - Clara Tait, Time OutAt a railway station, everyday dramas are constantly being played out: meeting, parting, anticipating, escaping. The atmosphere is an odd mix of tension and contemplation. Everyone is waiting for something to happen or moving between events. In a station we are forced into proximity. We observe one another yet behave as if being in a crowd confers invisibility. We tend to assume that we are neither overheard nor overlooked. This book derives from a sound work, also called Audio Obscura. Commissioned by Artangel and Manchester International Festival, it was created for Manchester, Piccadilly and St Pancras International stations, where these photographs were taken.The idea comes from the camera obscura, or "dark room", a once popular form of entertainment and artist's tool which uses a small aperture and mirrors to project a reflection of the passing world. A form of proto-cinema, the camera obscura was in part what led to early photography, as people strove to fix the images it produced.As Lavinia Greenlaw writes in her introduction, "All of my work has, in one form or another, been an exploration of the point at which we start to make sense of things; an attempt to arrest and investigate that moment, to separate its components and test their effects. Audio Obscura extends this to the act of listening, or dark listening, in which unconscious aspects of perception are brought to light in ourselves."

In the early 1970s, Nancy Rexroth began photographing the rural landscapes, children, white frame houses, and domestic interiors of southeastern Ohio with a plastic toy camera called the Diana. Working with the camera’s properties of soft focus and vignetting, and further manipulating the photographs by deliberately blurring or sometimes overlaying them, Rexroth created dreamlike, poetic images of “my own private landscape, a state of mind.” She called this state IOWA because the photographs seemed to reference her childhood summer visits to relatives in Iowa. Rexroth self-published her evocative images in 1977 in the book IOWA, and the photographic community responded immediately and strongly to the work. Aperture published a portfolio of IOWA images in a special issue, The Snapshot, alongside the work of Robert Frank, Garry Winogrand, Lee Friedlander, and Emmet Gowin. The International Center for Photography, the Corcoran Gallery of Art, and the Smithsonian Institution included IOWA images in group exhibitions.Forty years after its original publication, IOWA has become a classic of fine art photography, a renowned demonstration of Rexroth’s ability to fashion a world of surprising aesthetic possibilities using a simple, low-tech dollar camera. Long out of print and highly prized by photographers and photobook collectors, IOWA is now available in a hardcover edition that includes twenty-two previously unpublished images. Accompanying the photographs are a new foreword by Magnum photographer and book maker Alec Soth and an essay by internationally acclaimed curator Anne Wilkes Tucker, who affirms the continuing power and importance of IOWA within the photobook genre. New postscripts by Nancy Rexroth and Mark L. Power, who wrote the essay in the first edition, complete the volume.

Remote Sensing of Impervious Surfaces in Tropical and Subtropical Areas offers a complete and thorough system for using optical and synthetic aperture radar (SAR) remote sensing data for improving impervious surface estimation (ISE). Highlighting tropical and subtropical areas where there is significant cloud occurrence and varying phenology, the book addresses the challenges impacting impervious surfaces in tropical and subtropical zones. It examines the potential for estimating urban impervious surfaces in a rainy and cloudy environment, considers the difficulties encountered when using optical remote sensing in this type of climate, and assesses existing methods employing remote sensing data for accurate ISE in tropical and subtropical regions. Using the results of comparative studies conducted during the four seasons and in six different cities (Guangzhou, Shenzhen, Hong Kong, Mumbai, Sao Paulo, and Cape Town), the authors develop a framework for ISE using optical and SAR image data. They address the advantages and disadvantages of optical and SAR data, consider fusion strategies for combining optical and SAR data, and examine different feature extractions for optical and SAR data. They also detail the limitations of the research, suggest possible topics for future analysis, and cover previous findings on the synergistic use of optical and SAR data. Concentrates on the effect a tropical and subtropical urban climate can have on impervious surface estimation (ISE) Reviews literature on the significance of ISE and the phonological and climatic characteristics of tropical and subtropical regions Describes datasets including satellite data, digital orthophoto data, in situ data, and more Remote Sensing of Impervious Surfaces in Tropical and Subtropical Areas investigates the state of the art in creating new algorithms for digital images processing and remotely sensed images classification, as well as in developing the meteorological modeling of urban heat islands, and the hydrological modeling of surface run-off and urban floods.

Tra Esino e San Vicino offre una lettura completamente nuova dell'architettura religiosa che, a cavallo tra il romanico e il gotico, si afferma al centro delle Marche, in un'area denominata Valle di S. Clemente. Qui, a partire dall'XI secolo, si assiste ad una straordinaria fioritura di insediamenti costituiti da abbazie, eremi, pievi, di cui spesso si conservano le strutture più antiche, la maggior parte ancora leggibili nella loro stratigrafia. Attraverso un'analisi dettagliata delle strutture murarie, condotta secondo i più moderni criteri metodologici dell'archeologia dell'architettura, e una rilettura critica delle fonti scritte, è stato possibile ricostruire le diverse fasi edilizie che hanno segnato la storia delle chiese esaminate, attestante le trasformazioni subite nel tempo a causa delle mutate esigenze liturgiche e dei frequenti eventi distruttivi. Sono così riemerse le articolate configurazioni architettonico-liturgiche di alcuni tra i più importanti edifici religiosi dell'Italia centrale, a cominciare dalla cripta di S. Salvatore di Valdicastro, prima tomba di S. Romualdo, di cui è stato possibile recuperare il "funzionamento" liturgico, fino ad alcune strutture complesse ed estremamente rare - ma non inedite nel panorama architettonico marchigiano - di cui la documentazione scritta non porta traccia, come i matronei di S. Elena all'Esino o i balconi interni di S. Urbano e S. Elena all'Esino. Inoltre, la rielaborazione della documentazione raccolta esaminando le strutture sopraelevate ha permesso di produrre una classificazione delle tecniche murarie e delle tipologie di aperture, organizzate nei relativi atlanti. In questo modo è stato possibile mappare il percorso di alcune maestranze edili, e più in generale è stato possibile determinarne i caratteri specifici e stabilirne la circolazione, che ha fatto emergere il ruolo determinante di alcuni 'magistri' e delle relative officine nell'elaborazione del paesaggio architettonico di questo territorio.

A half-century of social change in America, documented in the writings of Danny Lyon, photographer and author of The Bikeriders and The Destruction of Lower Manhattan “From the beginning, even before he left the University of Chicago and headed south to take up a position as the first staff photographer for the Student Nonviolent Coordinating Committee, Danny Lyon dreamed of being an artist in language as well as in pictures,” writes Randy Kennedy in the introduction to American Blood. In 1961, at the age of 19, for example, Lyon penned a brutally satirical article for a student mimeo magazine in which he argued for the deterrent power of prime-time televised executions (“the show would open, no doubt, like a baseball game, with a rendition of the National Anthem”). Lyon is widely celebrated for his groundbreaking work in photography and film. Less recognized is the extensive body of writing that has broadened and reinforced his reach, in both the pages of his own publications and in others as varied as the Los Angeles Times, the New York Review of Books, Aperture, civil rights publications, underground magazines and Lyon's blog. This 400-page volume spans republished and previously unpublished texts from nearly six decades of his career, comprising a vast, meticulously archived history of American social change. Also included are conversations between Lyon and Hugh Edwards, Nan Goldin and Susan Meiselas. As Kennedy writes, Lyon’s collected writings, “remarkable as both artistic and moral models, remain far too little known, especially for an author who has seen what he has seen and possesses the rare ability to write about it as he speaks; Lyon is a world-class talker, funny, wise, sanguine and indefatigable.” Danny Lyon (born 1942) is one of the most influential documentary photographers of the last five decades. His many books include The Movement (1964), The Bikeriders, The Destruction of Lower Manhattan (1969), Knave of Hearts (1999), Like a Thief’s Dream (2007) and Deep Sea Diver (2011).

Chalk has proved to be one of the more difficult rocks to core-log as it breaks up readily during the drilling process leading to core-loss and destructuring, particularly where flints, nodular chalks and/or fractures are present. One of the greatest difficulties is the identification of chalk engineering grade which relies heavily on fracture aperture. Obtaining the correct grade to define the depth of weathering and the depth at which fractures become closed is essential whether for tunnels in London or for wind turbine piled foundations in the offshore chalks. Very few geologists and engineers have had the opportunity to study field sections in the Chalk so there is little visual appreciation of the grades or the variation to expect or even what flint bands look like. To partly overcome this difficulty, both field and core sections are illustrated in this book. Equally important to recognising Chalk grade is the building of conceptual ground models for construction projects. This can only be achieved if the various Chalk formations, beds and marker beds can be identified from cores and then boreholes correlated using the marker beds.The Chalk stratigraphy is accordingly covered with key formations and marker beds illustrated, and the best field sections for viewing them identified. This book is based on the standard lithostratigraphy and method of engineering description of Chalk developed over many years. Also important are over 3000 onshore and offshore chalk-cored boreholes undertaken by the author over more than 30 years. In addition, typical lithologies and weathering profiles representing the Chalk formations likely to be encountered in the various onshore and offshore construction projects are illustrated using field exposures, rotary core samples and geophysical borehole wire-line logs. There will be geological settings where information on the Chalk is poor and unexpected lithologies and stratigraphies may be found. This book will enable geologists to work from first principles to construct a lithostratigraphy and define weathering boundaries.

There are many general titles on landscape photography, but few that really tackle the issue of composition in great depth. The Art of Landscape Photography assumes a good working knowledge of the technical basics – such as correct exposure, filtration, and sharpness – and concentrates on the 'heart and soul' of landscape photography: the principles of composition and aesthetic design to convey meaning and emotion. While technique will not be ignored, the emphasis will be on how it impacts on the aesthetics of the image; for example, using filtration to enhance the mood of a scene rather than simply to balance the extremes of contrast. Because of the nature of the subject matter, this is very much a picture-led book, with numerous example pictures to illustrate the compositional points being discussed. At the back of the book there will be thumbnails of all the pictures used, with a summary of the technical details – camera, lens, ISO, shutter speed, aperture, filtration – to ensure that those who crave technical information are not disappointed. AUTHORS: Mark Bauer is a professional landscape photographer specialising in atmospheric images of Dorset and the New Forest. He is a regular contributor to the UK photographic press with his dramatic images appearing in numerous national and county publications, in particular Digital SLR Photography magazine, on book covers, cards and calendars. Ross is an award-winning wildlife and landscape photographer, the author of several photography books, and a regular contributor to the photo press. Based in North Cornwall, England, Ross is best known for his beautiful macro and close-up images, and for evocative landscape photographs.

Brodie's decade-long record of his transient American life, brimming with poignant stories of those he encountered along the wayMike Brodie's first monograph, A Period of Juvenile Prosperity, touched down more than decade ago, depicting his fellow rail-riders and drifters in a rebellious and wildfire pursuit of adventure and freedom. Brodie leapt into the life of picture-making as if he was the first to do it, Danny Lyon wrote about the book in Aperture. Next came Tones of Dirt and Bone, a collection of earlier SX-70 pictures Brodie made when photography first led him to hopping freights, when he was known as The Polaroid Kidd. And then Brodie seemed to disappear from the art world as suddenly and mysteriously as he'd first appeared. Maybe his vanishing was another myth. Maybe it was just a necessary retreat. I was divorcing myself from all that, he says. I was growing up. I was pursuing this other life.If A Period of Juvenile Prosperity was a cinematic dream, Failing is the awakening and the reckoning: a raw, wounded and searingly honest photographic diary of a decade marked by love and heartbreak, loss and grief. Here is the flip side of the American dream, seen from within; here is bearing close witness to the brutal chaos of addiction and death; here are front-seat encounters with hitchhikers and kindred wanderers on society's edges, sustained by the ragtag community of the road. Failing often exists in darkness but is tuned to grace. Brodie's eye stays forever open to the strange and fleeting beauty that exists in forgotten placesthe open country and the lost horizons that sweep past dust-spattered windows in a spectral blur.Michael Brodie (born 1985) is the author of A Period of Juvenile Prosperity (2013) and Tones of Dirt and Bone (2015). He lives with his girlfriend in Biloxi, Mississippi, where the railroad is never far, just hidden in the trees from view. Unseen, it rattles the windows and floors of their apartment every time a train passes through.

Mary Mattingly is a visual artist. She founded Swale, an edible landscape on a barge in New York City. Docked at public piers but following waterways common laws, Swale circumnavigates New York's public land laws, allowing anyone to pick free fresh food. Swale instigated and co-created the "foodway" in Concrete Plant Park, the Bronx in 2017. The "foodway" is the first time New York City Parks is allowing people to publicly forage in over 100 years. It's currently considered a pilot project. Mattingly recently launched Public Water with More Art and completed a two-part sculpture “Pull” for the International Havana Biennial with the Museo Nacional de Bellas Artes de la Habana and the Bronx Museum of the Arts, two spherical ecosystems that were pulled across Habana to Parque Central and the museum. In 2018 she received a commission from BRIC Arts Media to build "What Happens After" which involved dismantling a military vehicle (LMTV) that had been to Afghanistan and deconstructing its mineral supply chain. A group of artists including performance artists, veterans, and public space activists re-envisioned the vehicle for BRIC. In 2016 Mattingly led a similar project at the Museum of Modern Art. In 2014, an artist residency on the water called WetLand launched in Philadelphia and traveled to the Parrish Museum. It was employed by the University of Pennsylvania’s Environmental Humanities program until 2017. Mary Mattingly’s work has also been exhibited at Storm King, the International Center of Photography, the Seoul Art Center, the Brooklyn Museum, the New York Public Library, deCordova Museum and Sculpture Park, and the Palais de Tokyo. Her work has been featured in Aperture Magazine, Art in America, Artforum, Art News, Sculpture Magazine, The New York Times, New York Magazine, Financial Times, Le Monde Magazine, Metropolis Magazine, New Yorker, The Wall Street Journal, the Brooklyn Rail, and on BBC News, MSNBC, NPR, WNBC, and on Art21. Her work has been included in books such as the Whitechapel/MIT Press Documents of Contemporary Art series titled “Nature” and edited by Jeffrey Kastner, Triple Canopy’s Speculations, the Future Is... published by Artbook, and Henry Sayre’s A World of Art, 8th edition, published by Pearson Education Inc.

In a work that fundamentally recasts the history of colonial America, Wendy Warren shows how the institution of slavery was inexorably linked with the first century of English colonization of New England. While most histories of slavery in early America confine themselves to the Southern colonies and the Caribbean, New England Bound forcefully widens the historical aperture to include the entirety of English North America, integrating the famed "city on a hill" of seventeenth-century Puritan New England into the cruel Atlantic system from its very beginnings. Using original research culled from dozens of archives, Warren conclusively links the growth of the northern colonies to the Atlantic slave trade, showing how seventeenth-century New England’s fledgling economy derived its vitality from the profusion of ships that coursed through its ports, passing through on their way to and from the West Indian sugar colonies. What’s more, leading New England families like the Winthrops and Pynchons invested heavily in the West Indies, owning both land and human property, the profits of which eventually wended their way back north. That money, New England Bound shows, was the tragic fuel for the colonial wars of removal and replacement of New England Indians that characterized the initial colonization of the region. Warren painstakingly documents the little-known history of how Native Americans were systematically sold as slaves to plantations in the Caribbean, even in the first decades of English colonization. And even while New England Bound explains the way in which the Atlantic slave trade drove the colonization of New England, it also brings to light, in many cases for the first time ever, the lives of the thousands of reluctant Indian and African slaves who found themselves forced into the project of building that city on a hill. We encounter enslaved Africans working side jobs as con artists, enslaved Indians who protested their banishment to sugar islands, enslaved Africans who set fire to their owners’ homes and goods, and enslaved Africans who saved their owners’ lives. In Warren’s meticulous, compelling, and hard-won recovery of such forgotten lives, the true variety of chattel slavery in the Americas comes to light, and New England Bound becomes the new standard for understanding colonial America.

'A brilliant, very funny, very revealing autobiography-through-music. Maybe the best book ever written about being a rockstar' CAITLIN MORAN_______________________________________________________________Bono - artist, activist and the lead singer of Irish rock band U2 - has written his autobiography: honest and irreverent, intimate and profound, Surrender is the story of the remarkable life he's lived, the challenges he's faced and the friends and family who have shaped and sustained him.'When I started to write this book I was hoping to draw in detail what I'd previously only sketched in songs. The people, places, and possibilities in my life. Surrender is a word freighted with meaning for me. Growing up in Ireland in the seventies with my fists up (musically speaking), it was not a natural concept. A word I only circled until I gathered my thoughts for the book. I am still grappling with this most humbling of commands. In the band, in my marriage, in my faith, in my life as an activist. Surrender is the story of one pilgrim's lack of progress ... With a fair amount of fun along the way.' - BonoAs one of the music world's most iconic artists and the cofounder of organizations ONE and (RED), Bono's career has been written about extensively. But in Surrender, Bono's autobiography, he picks up the pen, writing for the first time about his remarkable life and those he has shared it with. In his unique voice, Bono takes us from his early days growing up in Dublin, including the sudden loss of his mother when he was 14, to U2's unlikely journey to become one of the world's most influential rock bands, to his more than 20 years of activism dedicated to the fight against AIDS and extreme poverty. Writing with candour, self-reflection, and humour, Bono opens the aperture on his life - and the family, friends and faith that have sustained, challenged and shaped him.Surrender's subtitle, "40 Songs, One Story," is a nod to the book's 40 chapters, which are each named after a U2 song. Bono has also created 40 original drawings for Surrender which will appear throughout the book.

In Making Photographs, photographer, educator, and author Ibarionex Perello teaches you how to develop and implement a visual workflow that allows you to create a repeatable process for your photography, so you can create consistently great images.With today’s photo technology, almost anyone can pick up a camera and create a photograph that is well-exposed and in focus. And if you take enough pictures, you’re bound to get lucky and create a few “keepers” that impress family and friends. But eventually, you hit a wall; you know you’re relying more on luck than skill. Even learning to control the fundamental, technical components of the craft—shutter speed, aperture, and ISO—only takes you so far. The real challenges remain: How can you learn to make good images consistently? And how can you really start to “see” photographic possibilities all around you?In Making Photographs, photographer, educator, and author Ibarionex Perello teaches you how to face and conquer such challenges. He shares the approach and techniques he’s honed over the last 15 years conducting workshops and teaching photography courses to countless students of the craft. The key to this approach, Ibarionex argues, is to develop and implement a visual workflow that allows you to create a repeatable process for your photography. This workflow revolves around the four “visual draws”—light and shadow, line and shape, color, and gesture. As Ibarionex discusses each of these visual draws, you’ll learn how to move beyond merely “looking” at the world around you to “seeing” photographic possibilities at every turn. It is this act of seeing that gives photography its magic—and you the vital tool you need to improve your work. Rather than simply taking pictures, you'll begin making photographs.Ibarionex also covers topics such as exposure, composition, preparation, lighting, the role of emotion, culling your images, self-assessment, and post-processing. Alongside discussion of these themes and principles, he presents the stories behind his photographs, which reveal his thought process as he works through a scene; shares entries from his personal photographic journal, relaying successes, failures, discoveries, and breakthroughs; and includes assignments and personal challenges to inspire and motivate you to put these principles into immediate action in your photography.

Text in English and German. The church rises to the challenge of providing a spiritual centre for Donau City, the new residential and commercial centre on the opposite bank of the Danube -- not as an act of coronation for the city in the sense of Taut's urban crown, as a temple or cathedral, but as miniature, as a demonstration of the power of the quiet as opposed to the loud, as an 'oasis in the diaspora', to use Karl Rahner's formulation about the parishes of the future. The building gives an impression of starkness: a hard cube, cut off at the corners, clad with sheets of black chromium steel. But it is only stark at first glance. A second glance shows that the hardness is a friendly hardness: because of the reflections that the material admits; because of the grid of the large-format sheets, to which the brightly gleaming drill-holes that cover the walls like fine gossamer respond; because of circular apertures that allow light to shine outwards after dark; because of large, rectangular windows in the receding corners that create a contrast with the closed quality of the building. Inside the starkness gives way altogether: a light space, which one comes into through an art-fully designed entrance. Originally a sparse covering for the space, which thrives mainly because of the light material -- birch wood -, because of the arrangement of the pews, which is as lively as it is peaceful -- segments of circles of different sizes, surrounding the dark syenite altar block in the form of an open circle -- and especially because of the wide range of circular light sources that render the introverted interior transparent, the large windows that create islands of light, the free-form aperture in the ceiling, which sends light gliding down on to the altar. Heinz Tesar's church continues a tradition of forward-looking modern church building, from Rudolf Schwarz's Fronleichnamskirche in Aachen via Egon Eiermann's Kaiser-Wilhelm-Gedachtniskirche in Berlin, Franz Fueg's Piuskirche in Meggen on Lake Lucerne to the new Herz-Jesu-Kirche in Munich by Allmann, Sattler and Wappner; and alongside all this there is also the tradition of a genuinely Viennese development of this theme, from Otto Wagner's Kirche am Steinhof to Ottokar Uhl's parish church Katharina von Siena.

“Ducks in a stream, the bridge at St. Anthony Falls, streets of cities and towns, a fish in a net, the glittering lakes seen under low skies. The Face of Minnesota is a fresh, simple, unpretentious statement of a place and time by people who know what Minnesota is because they live there.” —Minor White, Aperture, 1958 “John Szarkowski is the single most important curator that photography has ever had. Looking at his photographs created over the last fifty years makes me want to weep. They are truly American pictures; one feels his desire to show not just what America was but what it still can be.” —Ingrid Sischy, Vanity Fair, 2005 Originally commissioned to commemorate Minnesota’s centennial in 1958 and out of print for nearly forty years, The Face of Minnesota is a lost masterpiece of photography and an eloquent tribute to the people and places of the North Star state. Republished in celebration of the state’s sesquicentennial, this beautifully produced edition includes contemporary essays about John Szarkowski’s impact on American photography and introduces his work to new generations of Minnesotans. Featuring more than 175 arresting photographs as well as essays filled with wit and affection, The Face of Minnesota opens with this statement: “This book is about Minnesota now. But as a mature man carries on his face and in his bearing the history of his past, so does the look of a place today show its past-what it has been and what it has believed in.” Though Minnesota has changed dramatically during the past fifty years, The Face of Minnesota reveals the simple beauty of the imprint of the past and its deep resonance today. John Szarkowski (1925–2007) was director of the photography program at the Museum of Modern Art in New York, where he transformed our understanding of the art of photography through influential exhibitions and books, including Looking at Photographs (1973). In 2005 his work was surveyed in a traveling exhibition, accompanied by the book John Szarkowski: Photographs. Verlyn Klinkenborg joined the editorial board of the New York Times in 1997. He is the author of several works, including The Rural Life. Richard Benson has worked as a photographer and printer since 1966. He teaches at Yale University and is the coauthor, with John Szarkowski, of A Maritime Album: 100 Photographs and Their Stories.

A fallen regime. A missing child. A chance at freedom.By the #1 New York Times bestselling author of Divergent, Poster Girl is a haunting adult dystopian mystery that explores the expanding role of surveillance on society - an inescapable reality that we welcome all too easily.WHAT'S RIGHT IS RIGHT. Sonya Kantor knows this slogan - she lived by it for most of her life. For decades, everyone in the Seattle-Portland megalopolis lived under it, as well as constant surveillance in the form of the Insight, an ocular implant that tracked every word and every action, rewarding or punishing by a rigid moral code set forth by the Delegation.Then there was a revolution. The Delegation fell. Its most valuable members were locked in the Aperture, a prison on the outskirts of the city. And everyone else, now free from the Insight's monitoring, went on with their lives. Sonya, former poster girl for the Delegation, has been imprisoned for ten years when an old enemy comes to her with a deal: find a missing girl who was stolen from her parents by the old regime, and earn her freedom. The path Sonya takes to find the child will lead her through an unfamiliar, crooked post-Delegation world where she finds herself digging deeper into the past - and her family's dark secrets - than she ever wanted to.Praise for Veronica Roth 'Poster Girl cements Veronica Roth's status as a superstar' Gregg Hurwitz, #1 International bestselling author of the Orphan X series'Veronica Roth's latest outing will draw you into its broken world, and make you think more deeply of our own' Karin Slaughter, New York Times bestselling author of Girl, Forgotten'Roth weaves a tale of redemption and regret that kept me riveted and guessing until the last page' Hugh Howey, New York Times bestselling author of Wool and Across the Sand'Veronica Roth is the cure for all those humdrum 'one true saviour' narratives' Charlie Jane Anders, Hugo and Nebula Award-winning author of THE CITY IN THE MIDDLE OF THE NIGHT, on CHOSEN ONES'Roth has pulled off a virtuoso performance' Blake Crouch, bestselling author of DARK MATTER and RECURSION on CHOSEN ONES'Roth somehow manages to make universe-building look easy' Charles Yu, bestselling author of INTERIOR CHINATOWN on CHOSEN ONES

Introduced in 1967, and continuing in production until October 1979, the Bay was the successor to the legendary ‘split-screen’ Transporter, and is the second of five generations of van so far given the Transporter name by VW. Even the poorest examples of the ‘Bay’ now fetch significant money, and imports from drier climes continue to appear on British roads, so the case for restoring one of these hugely popular vehicles is increasingly attractive. Using the trusted Haynes practical step-by-step approach, this all-colour manual follows the restoration of a 1979 Devon camper from beginning to end, and provides expert advice on the problems likely to be encountered when working on vehicles that have seen over 35 years of use and, in Britain, as many years of rain, salt and mud. This is the only guide to restoring (or part-restoring) a ‘Bay’ you will ever need.

Ancient Rome was an imposing city even by modern standards, a sprawling imperial metropolis of more than a million inhabitants, a "mixture of luxury and filth, liberty and exploitation, civic pride and murderous civil war" that served as the seat of power for an empire that spanned from Spain to Syria. Yet how did all this emerge from what was once an insignificant village in central Italy? In S.P.Q.R., world-renowned classicist Mary Beard narrates the unprecedented rise of a civilization that even two thousand years later still shapes many of our most fundamental assumptions about power, citizenship, responsibility, political violence, empire, luxury, and beauty. From the foundational myth of Romulus and Remus to 212 ce—nearly a thousand years later—when the emperor Caracalla gave Roman citizenship to every free inhabitant of the empire, S.P.Q.R. (the abbreviation of "The Senate and People of Rome") examines not just how we think of ancient Rome but challenges the comfortable historical perspectives that have existed for centuries by exploring how the Romans thought of themselves: how they challenged the idea of imperial rule, how they responded to terrorism and revolution, and how they invented a new idea of citizenship and nation. Opening the book in 63 bce with the famous clash between the populist aristocrat Catiline and Cicero, the renowned politician and orator, Beard animates this “terrorist conspiracy,” which was aimed at the very heart of the Republic, demonstrating how this singular event would presage the struggle between democracy and autocracy that would come to define much of Rome’s subsequent history. Illustrating how a classical democracy yielded to a self-confident and self-critical empire, S.P.Q.R. reintroduces us, though in a wholly different way, to famous and familiar characters—Hannibal, Julius Caesar, Cleopatra, Augustus, and Nero, among others—while expanding the historical aperture to include those overlooked in traditional histories: the women, the slaves and ex-slaves, conspirators, and those on the losing side of Rome’s glorious conquests. Like the best detectives, Beard sifts fact from fiction, myth and propaganda from historical record, refusing either simple admiration or blanket condemnation. Far from being frozen in marble, Roman history, she shows, is constantly being revised and rewritten as our knowledge expands. Indeed, our perceptions of ancient Rome have changed dramatically over the last fifty years, and S.P.Q.R., with its nuanced attention to class inequality, democratic struggles, and the lives of entire groups of people omitted from the historical narrative for centuries, promises to shape our view of Roman history for decades to come.

A fallen regime. A missing child. A chance at freedom.By the #1 New York Times bestselling author of Divergent, Poster Girl is a haunting adult dystopian mystery that explores the expanding role of surveillance on society - an inescapable reality that we welcome all too easily.WHAT'S RIGHT IS RIGHT. Sonya Kantor knows this slogan - she lived by it for most of her life. For decades, everyone in the Seattle-Portland megalopolis lived under it, as well as constant surveillance in the form of the Insight, an ocular implant that tracked every word and every action, rewarding or punishing by a rigid moral code set forth by the Delegation.Then there was a revolution. The Delegation fell. Its most valuable members were locked in the Aperture, a prison on the outskirts of the city. And everyone else, now free from the Insight's monitoring, went on with their lives. Sonya, former poster girl for the Delegation, has been imprisoned for ten years when an old enemy comes to her with a deal: find a missing girl who was stolen from her parents by the old regime, and earn her freedom. The path Sonya takes to find the child will lead her through an unfamiliar, crooked post-Delegation world where she finds herself digging deeper into the past - and her family's dark secrets - than she ever wanted to.Praise for Veronica Roth 'Poster Girl cements Veronica Roth's status as a superstar' Gregg Hurwitz, #1 International bestselling author of the Orphan X series'Veronica Roth's latest outing will draw you into its broken world, and make you think more deeply of our own' Karin Slaughter, New York Times bestselling author of Girl, Forgotten'Roth weaves a tale of redemption and regret that kept me riveted and guessing until the last page' Hugh Howey, New York Times bestselling author of Wool and Across the Sand'Veronica Roth is the cure for all those humdrum 'one true saviour' narratives' Charlie Jane Anders, Hugo and Nebula Award-winning author of THE CITY IN THE MIDDLE OF THE NIGHT, on CHOSEN ONES'Roth has pulled off a virtuoso performance' Blake Crouch, bestselling author of DARK MATTER and RECURSION on CHOSEN ONES'Roth somehow manages to make universe-building look easy' Charles Yu, bestselling author of INTERIOR CHINATOWN on CHOSEN ONES

This textbook is an introduction to microwave engineering. The scope of this book extends from topics for a first course in electrical engineering, in which impedances are analyzed using complex numbers, through the introduction of transmission lines that are analyzed using the Smith Chart, and on to graduate level subjects, such as equivalent circuits for obstacles in hollow waveguides, analyzed using Green’s Functions. This book is a virtual encyclopedia of circuit design methods. Despite the complexity, topics are presented in a conversational manner for ease of comprehension. The book is not only an excellent text at the undergraduate and graduate levels, but is as well a detailed reference for the practicing engineer. Consider how well informed an engineer will be who has become familiar with these topics as treated in High Frequency Techniques: (in order of presentation) Brief history of wireless (radio) and the Morse codeU.S. Radio Frequency AllocationsIntroduction to vectorsAC analysis and why complex numbers and impedance are usedCircuit and antenna reciprocityDecibel measureMaximum power transferSkin effectComputer simulation and optimization of networksLC matching of one impedance to anotherCoupled ResonatorsUniform transmission lines for propagationVSWR, return Loss and mismatch errorThe Telegrapher Equations (derived)Phase and Group VelocitiesThe Impedance Transformation Equation for lines (derived)Fano's and Bode's matching limitsThe Smith Chart (derived)Slotted Line impedance measurementConstant Q circles on the Smith ChartApproximating a transmission line with lumped L's and C'sABCD, Z, Y and Scattering matrix analysis methods for circuitsStatistical Design and Yield Analysis of productsElectromagnetic FieldsGauss's LawVector Dot Product, Divergence and CurlStatic Potential and GradientAmpere's Law and Vector CurlMaxwell's Equations and their visualizationThe LaplacianRectangular, cylindrical and spherical coordinatesSkin EffectThe Wave EquationThe Helmholtz EquationsPlane Propagating WavesRayleigh FadingCircular (elliptic) PolarizationPoynting's TheoremEM fields on Transmission LinesCalculating the impedance of coaxial linesCalculating and visualizing the fields in waveguidesPropagation constants and waveguide modesThe Taylor Series ExpansionFourier Series and Green's FunctionsHigher order modes and how to suppress themVector Potential and Retarded PotentialsWire and aperture antennasRadio propagation and path lossElectromagnetic computer simulation of structuresDirectional couplersThe Rat Race HybridEven and Odd Mode Analysis applied to the backward wave couplerNetwork analyzer impedance and transmission measurementsTwo-port Scattering Parameters (s matrix)The Hybrid Ring couplerThe Wilkinson power dividerFilter design: Butterworth, Maximally flat & Tchebyscheff responsesFilter QDiplexer, Bandpass and Elliptic filtersRichard's Transformation & Kuroda’s IdentitiesMumford's transmission line stub filtersTransistor Amplifier Design: gain, biasing, stability, and conjugate matchingNoise in systems, noise figure of an amplifier cascadeAmplifier non-linearity, and spurious free dynamic rangeStatistical Design and Yield Analysis

A TLS, SPECTATOR AND TIME MAGAZINE BOOK OF THE YEAR 2023FINALIST FOR THE NBCC AWARD FOR POETRY 2023'Celebrating the incredible moral clarity, beauty, fearlessness and power of the spirit of Saskia Hamilton - and of her poetry' Jorie Graham'Full of delicate and muscular truths and graced with rare intelligence, this posthumous volume offers the gifts of a uniquely sensitive mind' Publisher's Weekly (starred review)'To read Saskia Hamilton's opening poem in her forthcoming collection, All Souls, is to move through time in acts of seeing and of noting what is seen . . . For now, the day seems to say, Let the ordinary amaze, it's the grace we hold . . . Hamilton rests her sights on what can be apprehended from a bed, sofa, chair, or window, and named in the quotidian. These small recognitions ensure a life's weightiness, wariness, worthiness' Claudia RankineWho becomes familiar with mortalillness for very long. I was a stranger, &c.Not everyone appreciates it, noone finds being the third personbecoming, it's never accurate,and then one is headed for the past tense.Futurity that was once a lark, a gamble,a chance messenger, traffic and trade, under sail.The boy touches your arm in his sleepfor ballast. It's warm in the hold. Betweenship and sky, the bounds of sightalone, sphere so bounded.-from 'All Souls'In All Souls, Saskia Hamilton transforms compassion, fear, expectation, and memory into art of the highest order. Judgment is suspended as the poems and lyric fragments make an inventory of truths that carry us through night's reckoning with mortal hope into daylight. But even daylight - with its escapements and unbreakable numbers, 'restless, / irregular light and shadow, awakened' - can't appease the crisis of survival at the heart of this collection. Marked with a new openness and freedom - a new way of saying that is itself a study of what can and can't be said-the poems give way to Hamilton's mind, and her unerring descriptions of everyday life: 'the asphalt velvety in the rain.'The central suite of poems vibrates with a ghostly radioactive attentiveness, with care unbounded by time or space. Its impossible charge is to acknowledge and ease suffering with a gaze that both widens and narrows its aperture. Lightly told, told without sentimentality, the story is devastating. A mother prepares to take leave of a young son. Impossible departure. 'A disturbance within the order of moments.' One that can't be stopped, though in these poems language does arrest and in some essential ways fix time.Tenderness, courage, refusal, and acceptance infuse this work, illuminating what Elizabeth Hardwick called 'the universal unsealed wound of existence.'

A far-ranging critique of the rise of authoritarianism and white nationalism in the US and the consequences for democracy.In this searing critique of the Trump presidency and the rise of authoritarianism in the U.S., Henry Giroux asks, How have we arrived here, and what can be done? In a discussion of events that ranges from the Administration's ongoing attempts to repeal Obamacare and its anti-immigration policies and travel bans, to the normalization of a culture of cruelty and the "weaponization of ignorance," Giroux details the urgency of our current crisis.Giroux explores the political dystopias—those of recent history and those depicted in some of the classics of Western literature—that result when authoritarian forces outmaneuver accountability. He argues that only through increased civic investment in multicultural democracy, education, and resistance can we hope to push back the ominous convergence of white nationalism and elite economic interests.Praise for American Nightmare:"In this current era of corporate media misdirection and misinformation . . . Henry Giroux is one of the few great political voices of today, with powerful insight into the truth. Dr. Giroux is defiantly explaining, against the grain, what's REALLY going on right now, and doing so quite undeniably. Simply put, the ideas he brings forth are a beacon that need to be seen and heard and understood in order for the world to progress."—Julian Casablancas, lead vocalist for The Strokes"In frightening times like these, what is desperately needed is an informed and wise voice that speaks clearly and with conviction about the situation we are in, and what can be done. Henry Giroux is one of the great public intellectuals of our times, and American Nightmare is exactly the book for people grappling with how to understand the Trump era and how to proceed. This is precisely the book that needs to be shared with friends and acquaintances. It will provoke hard thinking, bring clarity, and stimulate much needed conversation and action."—Robert W. McChesney, co-author of People Get Ready: The Fight Against a Jobless Economy and a Citizenless Democracy"We have no greater chronicler of these dystopian times. Giroux's critique cuts to the crux of today’s authoritarian crisis, yet his voice remains of one hope that the people may collectively regain control. Even while living though systemic efforts to privatize hope, Giroux’s critique enacts the sort of shared resistance that can effectively challenge authoritarianism. American Nightmare demonstrates how we can resist the normalization of hate, authoritarianism and alienation in Trump’s America. He shows us that not only are we not alone, but we are among a majority who oppose the cruelties of American social policies."—David H. Price, author of Cold War Anthropology: The CIA and the Growth of Dual Use Anthropology"At a moment when the news cycle presents the dangers of Trumpian authoritarianism through disjointed and discrete hottakes, Giroux's wide-reaching analysis accounts for our current American nightmare with necessary historical context, and in so doing creates an aperture for resistance more meaningful than a hashtag."—Natasha Lennard, contributing writer for The Intercept, co-editor of Violence: Humans in Dark Times"In this passionately argued volume, Henry Giroux, long known for his critical commentaries on the de-democratization of the U.S.A., on its rising inequ(al)ity and neoliberal excesses, reflects very thoughtfully on the specter of Trump’s America: on its violence, cruelty, and incivility, its burgeoning authoritarianism, its inexorable edging toward a Grave Neo World: in short, a rising specter that demands to be countered at all cost if the U.S. is to be rescued from itself.”—John Comaroff, Professor of African and African American Studies and of Anthropology, Harvard University
