Book Description
Adaptive detection of signals embedded in correlated Gaussian noise has been an active field of research in the last decades. This topic is important in many areas of signal processing such as, just to give some examples, radar, sonar, communications, and hyperspectral imaging. Most of the existing adaptive algorithms have been designed following the lead of the derivation of Kelly's detector which assumes perfect knowledge of the target steering vector. However, in realistic scenarios, mismatches are likely to occur due to both environmental and instrumental factors. When a mismatched signal is present in the data under test, conventional algorithms may suffer severe performance degradation. The presence of strong interferers in the cell under test makes the detection task even more challenging. An effective way to cope with this scenario relies on the use of "tunable" detectors, i.e., detectors capable of changing their directivity through the tuning of proper parameters. The aim of this book is to present some recent advances in the design of tunable detectors and the focus is on the so-called two-stage detectors, i.e., adaptive algorithms obtained cascading two detectors with opposite behaviors. We derive exact closed-form expressions for the resulting probability of false alarm and the probability of detection for both matched and mismatched signals embedded in homogeneous Gaussian noise. It turns out that such solutions guarantee a wide operational range in terms of tunability while retaining, at the same time, an overall performance in presence of matched signals commensurate with Kelly's detector.

Book Description
1961. A squadron of Vulcan aircraft, Britain's most lethal nuclear bomber, flies towards the east coast of the United States. Highly manoeuvrable, the great delta-winged machines are also equipped with state of the art electronic warfare devices that jam American radar systems. Evading the fighters scrambled to intercept them, the British aircraft target Washington and New York, reducing them to smoking ruins. They would have done, at least, if this were not an exercise. This extraordinary raid (which actually took place) opens James Hamilton-Paterson's remarkable novel about the lives of British pilots at the height of the Cold War, when aircrew had to be on call 24 hours a day to fly their nuclear-armed V-bombers to the Western USSR and devastate the lives of millions. This is the story of Squadron-Leader Amos McKenna, a Vulcan pilot who is suffering from desires and frustrations that are tearing his marriage apart and making him question his ultimate loyalties. Relations with the American cousins are tense; the future of the RAF bomber fleet is in doubt. And there is a spy at RAF Wearsby, who is selling secrets to his Russian handlers in seedy East Anglian cafes. A macabre Christmas banquet at which aircrew under intolerable pressures go crazy, with tragic consequences, and a dramatic and disastrous encounter with the Americans in the Libyan desert, are among the high points of a novel that surely conveys the beauty and danger of flying better than any other in recent English literature.

Book Description
Investigating the nature, drivers and sources of innovation in Africa, this book examines the channels for effective diffusion of innovation in and to Africa under institutional, resource and affordability constraints. Fu draws on almost a decade of research on innovation in Africa to explore these issues and unpack the process, combining a rigorous statistical analysis of a purposely designed multi-wave, multi-country survey with in-depth studies of representative cases. Building on this research, Fu argues that African firms are innovative but unsupported. Those 'under-the-radar' innovations that widely exist in Africa as a result of the constraints are not sufficient to enable Africa to leapfrog the innovation gap in the era of the fourth Industrial Revolution. This is the first comprehensive analysis of the creation and diffusion of innovation in low income countries. It also provides the first survey-based analysis of innovation in the informal economy.

Book Description
They advertised soft drinks on fruit and underwear on sidewalks. They employed Ed Koch to bring Snapple to the American heartland. They even used Imelda Marcos to sell Kenneth Cole shoes. Advertising innovators Jon Bond and Richard Kirshenbaum have come up with more outrageously clever ways to get past consumers' detectors than anyone else in advertising today. And now, they're finally ready to reveal their methods. In Under the Radar, Kirshenbaum and Bond chronicle their meteoric rise from a one-room, two-man Lower East Side stringer operation to Kirshenbaum Bond & Partners, one of today's hottest agencies. They share the lessons they learned along the way and describe the evolution of their unique "under-the-radar" approach to grabbing and holding the attention of today's "been there, done that" consumers. Under the Radar offers advertising and marketing professionals a deeply probing and instructive look at the nature of advertising and marketing in an age of information overload. Kirshenbaum and Bond provide a cogent analysis of how the world has changed since David Ogilvy laid down his ironclad rules for successful advertising. And, using in-depth critiques of many of today's best (and worst) ad campaigns, they describe what it takes to break through the defensive screens of a population bombarded by 1,500 ad messages each day. You'll learn all about cutting-edge research techniques KB&P and other front-running agencies have developed for getting inside the heads and hearts of real people, and, just as important, how to use that knowledge to get ad-weary consumers to tune in rather than zone out. You'll also learn about the latest trends in integrated marketing, media planning, and guerrilla marketing, as well as new ways of structuring an agency in order to stimulate "under-the-radar" thinking. Offering valuable lessons from the founders of one of today's most innovative and successful advertising firms, Under the Radar is essential reading for absolutely anyone involved in selling to consumers, from self-employed copywriters to marketing VPs at Fortune 500 companies. "Under the Radar: Talking to Today's Cynical Consumer is a valuable and important new tool for the advertising industry from two pros at one of the hottest shops in town. Jonathan Bond and Richard Kirshenbaum offer valuable insights and creative solutions on how to break through the clutter to make sure the consumer gets the message." —O. Burtch Drake, President and CEO American Association of Advertising Agencies "Kirshenbaum and Bond's genius is their capacity to cut through informational clutter and reach the grass roots. In the war to save New York's drinking water, Kirshenbaum and Bond showed us how to speak truth to power--and be heard!" —Robert F. Kennedy, Jr. "This book is the next best thing to actually working with Bond and Kirshenbaum. They are good! They know when to listen and when to argue with a client. They're not just smart and creative, they are serious strategic thinkers." —Roger Ailes, Chairman and CEO, Fox News "If you want to understand how ad executives create smart, innovative advertising, Richard and Jon's book is a must read." —Valerie Salembier, Publisher, Esquire magazine "Any book that helps a company deal with our over-communicated world is worth reading. Under the Radar is definitely one of those books." —Jack Trout, Trout & Partners Ltd. author of The New Positioning: The Latest on the World's #1 Business Strategy

Book Description
In 1993, the nation exploded into anti-same sex marriage fervor when the Hawaii Supreme Court issued its decision to support marriage equality for gay and lesbian couples. Opponents feared that all children, but especially those raised by lesbian or gay couples, would be harmed by the possibility of same-sex marriage, and warned of the consequences for society at large. Congress swiftly enacted the Defense of Marriage Act, defining marriage as between a man and a woman, and many states followed suit. Almost a decade before the Hawaii court issued its decision, however, several courts in multiple states had granted gay and lesbian couples co-parenting status, permitting each individual in the couple to be legally recognized as joint parents over their children. By 2006, advocates in half the states had secured court decisions supporting gay and lesbian co-parenting, and incurred far fewer public reprisals than on the marriage front. What accounts for the stark difference in reactions to two contemporaneous same-sex family policy fights? In Below the Radar, Alison Gash argues that advocacy visibility has played a significant role in determining whether advocacy efforts become mired in conflict or bypass hostile backlash politics. Same-sex parenting advocates are not alone in crafting low-visibility advocacy strategies to ward off opposition efforts. Those who operate, reside in, and advocate for group homes serving individuals with disabilities have also used below-the-radar strategies to diminish the damage cause by NIMBY ("not in my back yard") responses to their requests to move into single-family neighborhoods. Property owners have resorted to slander, subterfuge, or even arson to discourage group homes from locating in their neighborhoods, and for some advocates, secrecy provides the best elixir. Not every fight for civil rights grabs headlines, but sometimes, this is by design. Gash's groundbreaking analyses of these strategies provide a glimpse of the prophylactic and palliative potential of low-visibility advocacy.

Book Description
It is rare for a complete biography of an Australian scientist, particularly of an Australian woman scientist, to be published. It is rarer for such a book to be co-authored by an American. Although scientists have written discourses on the history of their discipline, it is most unusual for a scientist to write a full length biography of a colleague in his ?eld. It is also uncommon for a man to write about an Australian woman scientist; most of the work on Australian women scientists has been done by other women. However, these authors, both distinguished researchers in the ?eld of radio astr- omy, became so interested in the history of their discipline and in the career of the pioneer radio astronomer Ruby Payne-Scott that they spent some years bringing this book to fruition. Until relatively recently, Ruby Payne-Scott had been the only woman scientist mentioned brie?y in histories of Australian science or of Australian radio astronomy. This book will be an invaluable resource for anyone interested in these disciplines. Being scientists themselves, the authors explain Payne-Scott’s scienti?c work in detail; therefore, the value and importance of her contributions can, for the ?rst time, be recognised, not only by historians but also by scientists.

A NEW YORK TIMES CRITICS' TOP BOOK OF THE YEAR • BOOKLISTS' EDITOR'S CHOICE • ONE OF NPR'S BEST BOOK OF THE YEAR “At once a film book, a history book, and a civil rights book.… Without a doubt, not only the very best film book [but] also one of the best books of the year in any genre. An absolutely essential read.” —Shondaland This unprecedented history of Black cinema examines 100 years of Black movies—from Gone with the Wind to Blaxploitation films to Black Panther—using the struggles and triumphs of the artists, and the films themselves, as a prism to explore Black culture, civil rights, and racism in America. From the acclaimed author of The Butler and Showdown. Beginning in 1915 with D. W. Griffith's The Birth of a Nation—which glorified the Ku Klux Klan and became Hollywood's first blockbuster—Wil Haygood gives us an incisive, fascinating, little-known history, spanning more than a century, of Black artists in the film business, on-screen and behind the scenes. He makes clear the effects of changing social realities and events on the business of making movies and on what was represented on the screen: from Jim Crow and segregation to white flight and interracial relationships, from the assassination of Malcolm X, to the O. J. Simpson trial, to the Black Lives Matter movement. He considers the films themselves—including Imitation of Life, Gone with the Wind, Porgy and Bess, the Blaxploitation films of the seventies, Do The Right Thing, 12 Years a Slave, and Black Panther. And he brings to new light the careers and significance of a wide range of historic and contemporary figures: Hattie McDaniel, Sidney Poitier, Berry Gordy, Alex Haley, Spike Lee, Billy Dee Willliams, Richard Pryor, Halle Berry, Ava DuVernay, and Jordan Peele, among many others. An important, timely book, Colorization gives us both an unprecedented history of Black cinema and a groundbreaking perspective on racism in modern America.
