Books about Sigma delta from Amazon.com

This history of the largest block women's organization in the United States is not only the story of Delta Sigma Theta Sorority (DST), but also tells of the increasing involvement of black women in the political, social, and economic affairs of America. Founded at a time when liberal arts education was widely seen as either futile, dangerous, or impractical for blacks, especially women, DST is, in Giddings's words, a "compelling reflection of block women's aspirations for themselves and for society."

Giddings notes that unlike other organizations with racial goals, Delta Sigma Theta was created to change and benefit individuals rather than society. As a sorority, it was formed to bring women together as sisters, but at the some time to address the divisive, often class-related issues confronting black women in our society. There is, in Giddings's eyes, a tension between these goals that makes Delta Sigma Theta a fascinating microcosm of the struggles of black women and their organizations.

DST members have included Mary McLeod Bethune, Mary Church Terrell, Margaret Murray Washington, Shirley Chisholm, Barbara Jordan, and, on the cultural side, Leontyne Price, Lena Horne, Ruby Dee, Judith Jamison, and Roberta Flack. In Search of Sisterhood is full of compelling, fascinating anecdotes told by the Deltas themselves, and illustrated with rare early photographs of the Delta women.

The first African American fraternities and sororities were established at the turn of the twentieth century to encourage leadership, racial pride, and academic excellence among black college students confronting the legacy of slavery and the indignities of Jim Crow segregation. Black Greek-letter organizations were also created to foster a sense of community among African American students on college campuses, and among their ranks are legendary artists, politicians, theologians, inventors, intellectuals, educators, civil rights leaders, and athletes. Nikki Giovanni, Cornel West, Martin Luther King Jr., Shaquille O'Neal, Toni Morrison, Bill Cosby, and W.E.B. DuBois are all members of black fraternities and sororities, and these groups continue to have a strong presence on campuses today. Offering a comprehensive overview of the historical, cultural, political, and social circumstances that propelled the creation of these groups, this collection of original essays references the profound contributions that black Greek-letter organizations and their members have made to American history. The contributors also examine current black Greek life and culture, addressing issues such as hazing and branding that are, perhaps unfairly, often at the forefront of discussions about these organizations. African American Fraternities and Sororities is the authoritative history of these influential and sometimes controversial organizations..

Recipes, menus, and entertaining tips from one of the largest, most respected African-American women's organizations in the world.

Renowned for their dedication to service, the women of Delta Sigma Theta are equally admired for their chic signature style. In Occasions to Savor, the sorority shares its entertaining savvy with everyone-Deltas and non-Deltas alike.

Lavishly illustrated, this book features more than 250 recipes compiled from members of the sorority, plus entertaining tips and suggested menus for specific occasions, including bridal and baby showers, book club meetings, an after-theater dinner, a backyard barbecue, and Christmas dinner. Featuring a full range of recipes from appetizers, beverages, salads, soups, and entrées to breads, breakfast foods, and desserts, Occasions to Savor is much more than an entertaining guide and cookbook; it's a celebration of African-American women who have made significant contributions to society.

Engaging profiles of such influential Deltas as former Congresswoman Barbara Jordan; Mary McCleod Bethune, founder of Bethune-Cookman College and founder and first president of the National Council of Negro Women; renowned choreographer Judith Jamison; and Dorothy Height, civil rights activist and chair and president emerita of the National Council of Negro Women, reveal why the women of this esteemed organization are held up both as role models and mentors and as icons of style and substance..

Learn how to harness the power of delta-sigma data converters

Understanding Delta-Sigma Data Converters brings readers a clear understanding of the principles of delta-sigma (DeltaSigma) converter operation--analog to digital and digital to analog. It introduces the best computer-aided analysis and design techniques available. With an understanding of the great versatility of the DeltaSigma converter, readers can apply their new knowledge to a wide variety of applications, including digital telephony, digital audio, wireless and wired communications, medical electronics, and industrial and scientific instrumentation. The authors make the material accessible to all design engineers by focusing on developing an understanding of the physical operation rather than getting mired in complex mathematical treatments and derivations.

Written for entry-level readers, the publication has a natural flow that begins with basic concepts, enabling the readers to develop a solid foundation for the book's more complex material. The text, therefore, starts with a general introduction to the DeltaSigma converter, including a brief historical overview to place it in context. Next, the publication introduces the first-order DeltaSigma modulator, covering oversampling, noise-shaping, decimation filtering and other key concepts. Then, using the first-order modulator as a foundation, second and higher-order modulators are presented and analyzed. Finally, the authors delve into implementation considerations and present several design examples using the Delta-Sigma Toolbox.

Everything needed to facilitate quick comprehension and help readers apply their newly learned principles is provided:Simplified methods to understand complicated concepts such as spectral estimation and switched noiseReferences that lead to in-depth analysis of specialized topicsFigures and charts that illustrate complex design issuesConclusion section at the end of each chapter that highlights the key pointsReference manual for the Delta-Sigma Toolbox, along with numerous practical examples that illustrate the use of the Toolbox

This is essential reading for all design engineers who want to learn and fully harness the powerful capabilities of DeltaSigma data converters. Upper-level undergraduates and graduate students will find the book's logical organization and clear style, coupled with numerous practical examples, a great entry into the field..

Structured Analog CMOS Design describes a structured analog design approach that makes it possible to simplify complex analog design problems and develop a design strategy that can be used for the design of large number of analog cells. It intentionally avoids treating the analog design as a mathematical problem, developing a design procedure based on the understanding of device physics and approximations that give insight into parameter interdependences.

The proposed transistor-level design procedure is based on the EKV modeling approach and relies on the device inversion level as a fundamental design variable. Since all important design parameters can be expressed as continuous functions of the device inversion level, the design optimum as well as the technology limits can be easily found.

The basic design concept consists in analog cell partitioning into the basic analog structures and sizing of these basic analog structures in a predefined procedural design sequence. The procedural design sequence ensures the correct propagation of design specifications, the verification of parameter limits and the local optimization loops. The proposed design procedure is also implemented as a CAD tool that follows this book.

Finally, as a practical example, the design of analog amplifiers in a hybrid multi-bit Delta-Sigma modulator system is described in detail from system level to transistor level.
