Scalar diffraction from a circular aperture is a ubiquitous problem that arises in a variety of disciplines, such as optics (lenses), acoustics (speakers), electromagnetics (dish antennas), and ultrasonics (piston transducers). The problem endures despite centuries of research because each new generation of researchers rediscovers it and adds some novel insight or new result to the existing literature. Scalar Diffraction from a Circular Aperture promises a few new results and several novel insights, particularly with regard to spatial averaging. Although the text emphasizes ultrasonic diffraction, the results and insights developed are general and may be applied to the many practical problems involving scalar diffraction from a circular aperture. Included are novel insights on mirror-image diffraction, autoconvolution diffraction, and coherent and incoherent averaging. Examples from ultrasonic imaging, a coherent imaging modality, are used to develop a fairly general theory that connects over a century of research on scalar diffraction from a circular aperture. The material is based on a synthesis of mathematics, physical optics, linear systems theory, and scalar diffraction theory. Thus, engineers, scientists, mathematicians, and students working in optics, acoustics, antenna design, biomedical engineering, non-destructive testing, and astronomy will find Scalar Diffraction from a Circular Aperture interesting, provocative, and useful.
Mention southern drama at a cocktail party or in an American literature survey, and you may hear cries for "Stella!" or laments for "gentleman callers." Yet southern drama depends on much more than a menagerie of highly strung spinsters and steel magnolias. Charles Watson explores this field from its eighteenth- and nineteenth-century roots through the southern Literary Renaissance and Tennessee Williams's triumphs to the plays of Horton Foote, winner of the 1994 Pulitzer Prize. Such well known modern figures as Lillian Hellman and DuBose Heyward earn fresh looks, as does Tennessee Williams's changing depiction of the South—from sensitive analysis to outraged indictment—in response to the Civil Rights Movement. Watson links the work of the early Charleston dramatists and of Espy Williams, first modern dramatist of the South, to later twentieth-century drama. Strong heroines in plays of the Confederacy foreshadow the spunk of Tennessee Williams's Amanda Wingfield. Claiming that Beth Henley matches the satirical brilliance of Eudora Welty and Flannery O'Connor, Watson connects her zany humor to 1840s New Orleans farces. With this work, Watson has at last answered the call for a single-volume, comprehensive history of the South's dramatic literature. With fascinating detail and seasoned perception, he reveals the rich heritage of southern drama.
For the first time in ebook, renowned scholar Charles Johnson’s exploration of contemporary black literature and the meaning of the black experience as expressed through the writers Richard Wright, Jean Toomer, David Bradley, and others. Charles Johnson approaches contemporary black literature through the lens of phenomenology. Drawing on such philosophers as Heidegger, Husserl, Satre, and Dufrenne, Johnson addresses the esthetic and epistemological questions surrounding the black experience as expressed by African American authors. In exploring the works of Wright, Toomer, Bradley, and many more, Being and Race enlarges our vision of what fiction’s purpose is and how it arises from our common experiences.

For fans of HBO’s The Gilded Age, explore the dark side of the alluring world of America’s 19th century elite in this gripping series of riveting mysteries… New York City, 1894. The Democratic Party headquarters at Tammany Hall is a hotbed of cronyism, corruption, and intimidation. Private investigator Pamela Thompson’s close colleague at Jeremiah Prescott’s law firm, former NYPD detective Harry Miller, has had his own career tainted by scandal. Seven years ago, while investigating a case connected to Tammany Hall, he was falsely accused and wrongfully convicted of extortion. Miller’s conviction continues to cast its long shadow into his current life, so he seeks Pamela’s help in exonerating him. The key to uncovering the truth lies with the murder of a cabdriver and a missing portfolio with the potential to incriminate certain city aldermen of taking backroom bribes. But as Pamela and Miller follow the money trail to expose the conspiracy, they find their own lives in jeopardy…
Building beyond Lakoff's election-year best-seller, Don't Think of an Elephant, this new book shows how the values of American voters are dramatically shifting. With the arrival of the 2008 election year, a rising "feminized majority"-made up of both women and men-is emerging as the pivotal force in American politics. Emerging trends show these values are broadly progressive and address not just the needs of women but the general interests of society. They are held by women substantially more than by men but have become the values held by a majority of all voters, including millions of men. Like earlier eras in American history, such as the New Deal, the rise of the feminized majority today presents an opportunity for the Democrats to become the governing party for decades to come. Looking beyond the 2008 election, Adam and Derber describe a new political strategy that targets the feminized base and opens up a window for major social justice movements to make progressive change. Like Lakoff's, this striking new book-perfectly timed for election year 2008-offers a new vocabulary for every citizen who wants to understand (and reimagine) American politics. It will intrigue and provoke readers, stirring new conversation among progressives and new insights for every citizen interested in politics, morality, religion, values, and social justice.
