This book presents experimental techniques in the field of aerodynamics, a discipline that is essential in numerous areas, such as the design of aerial and ground vehicles and engines, the production of energy, and understanding the wind resistance of buildings. Aerodynamics is not only concerned with improving the performance and comfort of vehicles, but also with reducing their environmental impact. The book provides updated information on the experimental and technical methods used by aerodynamicists, engineers and researchers. It describes the various types of wind tunnels – from subsonic to hypersonic – as well as the problems posed by their design and operation. The book also focuses on metrology, which has allowed us to gain a detailed understanding of the local properties of flows, and examines current developments toward creating a methodology combining experiments and numerical simulations: the computer-assisted wind tunnel. Lastly, it offers an overview of experimental aerodynamics based on a prospective vision of the discipline, and discusses potential futures challenges. The book can be used as a textbook for graduate courses in aerodynamics, typically offered to students of aerospace and mechanical engineering programs, and as a learning tool for professionals and engineers in the fields of aerodynamics, aeronautics and astronautics automobile.

Experimental measurement techniques common to the compressible flow regime are introduced with particular emphasis on the unique challenges presented by high speed flows. Both experimental and numerical simulation work is supplied throughout to provide the reader with an overall perspective of current trends. - An introduction to current techniques in compressible turbulent flow analysis - An approach that enables engineers to identify and solve complex compressible flow challenges - Prediction methodologies, including the Reynolds-averaged Navier Stokes (RANS) method, scale filtered methods and direct numerical simulation (DNS) - Current strategies focusing on compressible flow control
From the author of Searching for Sylvie Lee, the iconic, New York Times-bestselling debut novel that introduced an important Chinese-American voice with an inspiring story of an immigrant girl forced to choose between two worlds and two futures. When Kimberly Chang and her mother emigrate from Hong Kong to Brooklyn squalor, she quickly begins a secret double life: exceptional schoolgirl during the day, Chinatown sweatshop worker in the evenings. Disguising the more difficult truths of her life—like the staggering degree of her poverty, the weight of her family's future resting on her shoulders, or her secret love for a factory boy who shares none of her talent or ambition—Kimberly learns to constantly translate not just her language but herself back and forth between the worlds she straddles. Through Kimberly's story, author Jean Kwok, who also emigrated from Hong Kong as a young girl, brings to the page the lives of countless immigrants who are caught between the pressure to succeed in America, their duty to their family, and their own personal desires, exposing a world that we rarely hear about. Written in an indelible voice that dramatizes the tensions of an immigrant girl growing up between two cultures, surrounded by a language and world only half understood, Girl in Translation is an unforgettable and classic novel of an American immigrant-a moving tale of hardship and triumph, heartbreak and love, and all that gets lost in translation.
The Least Restrictive Environment: Its Origins and Interpretations in Special Education examines issues of ethical leadership and clarifies instructional placement decisions that provide a full educational opportunity for students with disabilities.
Gian-Carlo Rota was born in Vigevano, Italy, in 1932. He died in Cambridge, Mas sachusetts, in 1999. He had several careers, most notably as a mathematician, but also as a philosopher and a consultant to the United States government. His mathe matical career was equally varied. His early mathematical studies were at Princeton (1950 to 1953) and Yale (1953 to 1956). In 1956, he completed his doctoral thesis under the direction of Jacob T. Schwartz. This thesis was published as the pa per "Extension theory of differential operators I", the first paper reprinted in this volume. Rota's early work was in analysis, more specifically, in operator theory, differ ential equations, ergodic theory, and probability theory. In the 1960's, Rota was motivated by problems in fluctuation theory to study some operator identities of Glen Baxter (see [7]). Together with other problems in probability theory, this led Rota to study combinatorics. His series of papers, "On the foundations of combi natorial theory", led to a fundamental re-evaluation of the subject. Later, in the 1990's, Rota returned to some of the problems in analysis and probability theory which motivated his work in combinatorics. This was his intention all along, and his early death robbed mathematics of his unique perspective on linkages between the discrete and the continuous. Glimpses of his new research programs can be found in [2,3,6,9,10].
obtained are still severely limited to low Reynolds numbers (about only one decade better than direct numerical simulations), and the interpretation of such calculations for complex, curved geometries is still unclear. It is evident that a lot of work (and a very significant increase in available computing power) is required before such methods can be adopted in daily's engineering practice. I hope to l"Cport on all these topics in a near future. The book is divided into six chapters, each· chapter in subchapters, sections and subsections. The first part is introduced by Chapter 1 which summarizes the equations of fluid mechanies, it is developed in C~apters 2 to 4 devoted to the construction of turbulence models. What has been called "engineering methods" is considered in Chapter 2 where the Reynolds averaged equations al"C established and the closure problem studied (§1-3). A first detailed study of homogeneous turbulent flows follows (§4). It includes a review of available experimental data and their modeling. The eddy viscosity concept is analyzed in §5 with the l"Csulting ~alar-transport equation models such as the famous K-e model. Reynolds stl"Css models (Chapter 4) require a preliminary consideration of two-point turbulence concepts which are developed in Chapter 3 devoted to homogeneous turbulence. We review the two-point moments of velocity fields and their spectral transforms (§ 1), their general dynamics (§2) with the particular case of homogeneous, isotropie turbulence (§3) whel"C the so-called Kolmogorov's assumptions are discussed at length.
Most natural and industrial flows are turbulent. The atmosphere and oceans, automobile and aircraft engines, all provide examples of this ubiquitous phenomenon. In recent years, turbulence has become a very lively area of scientific research and application, attracting many newcomers who need a basic introduction to the subject. An Introduction to Turbulent Flow, first published in 2000, offers a solid grounding in the subject of turbulence, developing both physical insight and the mathematical framework needed to express the theory. It begins with a review of the physical nature of turbulence, statistical tools, and space and time scales of turbulence. Basic theory is presented next, illustrated by examples of simple turbulent flows and developed through classical models of jets, wakes, and boundary layers. A deeper understanding of turbulence dynamics is provided by spectral analysis and its applications. The final chapter introduces the numerical simulation of turbulent flows. This well-balanced text will interest graduate students in engineering, applied mathematics, and the physical sciences.
This book presents a new method of asymptotic analysis of boundary-layer problems, the Successive Complementary Expansion Method (SCEM). The first part is devoted to a general presentation of the tools of asymptotic analysis. It gives the keys to understand a boundary-layer problem and explains the methods to construct an approximation. The second part is devoted to SCEM and its applications in fluid mechanics, including external and internal flows.
A good understanding of turbulent compressible flows is essential to the design and operation of high-speed vehicles. Such flows occur, for example, in the external flow over the surfaces of supersonic aircraft, and in the internal flow through the engines. Our ability to predict the aerodynamic lift, drag, propulsion and maneuverability of high-speed vehicles is crucially dependent on our knowledge of turbulent shear layers, and our understanding of their behavior in the presence of shock waves and regions of changing pressure. Turbulent Shear Layers in Supersonic Flow provides a comprehensive introduction to the field, and helps provide a basis for future work in this area. Wherever possible we use the available experimental work, and the results from numerical simulations to illustrate and develop a physical understanding of turbulent compressible flows.
The parish registers of St. James Parish on Herring Creek in Anne Arundel, MD - established 1692 - have long been out-of-print. Because of this, the author has transcribed the parish records books of the St. James Parish, along with those in Christ Church, West River, and Cliffs. All are in Anne Arundel County, MD and include dates back to the middle 1600's through the 1700s. There are two (2) sections to this book. The first is an index of all the individuals, birth, marriage and death dates along WITH their spouse's name. At the center of the book is the index for Part 1. Part 2 gives basically the same information but includes the place of birth, marriage and death, WITHOUT the names of their spouses. The index at the end of the book is for Part 2. To place these names into family groups, please see ancestry.com for the family file called Anne-Arundel.

This book gives a quick and clear history of Haiti for the past 500 years and how the country could grow with new policies and politics.
This book offers a novel but unified treatment of an established subject. Rather than describe the standard topics in fluid mechanics in traditional form, the book presents each topic as part of a wider class of problems so that a unity of concepts is emphasized over a unity of material.
This book attacks the conventional history of the press as a story of progress; offers a critical defence and history of public service broadcasting; provides a myth-busting account of the internet; a subtle account of the impact of social media and explores key debates about the role and politics of the media. It has become a standard book on media and other courses: but it has also gone beyond an academic audience to reach a wider public. Hailed as ‘a classic of media history and analysis’ by the Irish Times and a book that has ‘cracked the canon’ by the Times Higher, it has been translated into five languages. This edition contains six new chapters. These include the press and the remaking of Britain, the rise of the neo-liberal Establishment, the moral decline of journalism, the impact of social media and a history of attempts to reform the press. It contains new research on the relationship between programmes, institutions and society. It places key UK institutions in the wider context of international affairs and their impact. The book has been updated to take account of new developments like Brexit and the rise of Jeremy Corbyn and the shift in authority and legitimacy prompted by social media. It does this with a clear explanation of how policy can shape media outcomes.
This book is about how Australians have responded to stories about suffering and injustice in Australia, presented in a range of public media, including literature, history, films, and television. Those who have responded are both ordinary and prominent Australians—politicians, writers, and scholars. All have sought to come to terms with Australia's history by responding empathetically to stories of its marginalized citizens.Drawing upon international scholarship on collective memory, public history, testimony, and witnessing, this book represents a cultural history of contemporary Australia. It examines the forms of witnessing that dominated Australian public culture at the turn of the millennium. Since the late 1980s, witnessing has developed in Australia in response to the increasingly audible voices of indigenous peoples, migrants, and more recently, asylum seekers. As these voices became public, they posed a challenge not only to scholars and politicians, but also, most importantly, to ordinary citizens.When former Prime Minister Kevin Rudd delivered his historic apology to Australia's indigenous peoples in February 2008, he performed an act of collective witnessing that affirmed the testimony and experiences of Aboriginal Australians. The phenomenon of witnessing became crucial, not only to the recognition and reparation of past injustices, but to efforts to create a more cosmopolitan Australia in the present. This is a vital addition to Transaction's critically acclaimed Memory and Narrative series.
Students of nature around the world revere Eugene Odum as a founder and pioneer of ecosystem ecology. In this biography of Odum, Betty Jean Craige depicts the intellectual growth, creativity, and vision of the scientist who made the ecosystem concept central to his discipline and translated the principles of ecosystem ecology into lessons in preserving the natural environment. Placing Odum's achievements in historical context, Craige traces his life from his childhood through his education, his collaboration with his brother Howard T. Odum in developing methods to study ecosystems, his contributions to the field of radiation ecology, his emergence as an internationally distinguished educator of ecosystem ecology, and his environmental activism. Craige also describes Odum's role in the creation of the Savannah River Ecology Laboratory, the Marine Institute on Sapelo Island, and the Institute of Ecology at the University of Georgia, where he became identified with the statement "The ecosystem is greater than the sum of its parts." Odum's textbook Fundamentals of Ecology is a classic, published in numerous editions and translations worldwide. Odum achieved membership in the National Academy of Sciences, shared with his brother the prestigious Crafoord Prize for Ecology, accepted six honorary doctorates, and received numerous awards for environmental activities.
There were many little-known challenges to racial segregation before the landmark Supreme Court decision in Brown v. Board of Education (1954). The author's oral history interviews highlight civil rights protests seldom considered significant, but that help us understand the beginnings of the civil rights struggle before it became a mass movement. She brings to light many important but largely forgotten events, such as the often overlooked 1950s Oklahoma sit-in protests that provided a model for the better-known Greensboro, North Carolina, sit-ins. This book's significance lies in its challenge to perspectives that dominate scholarship on the civil rights movement. The broader concepts illustrated-including agency, culture, social structure, and situations-throughout this book open up substantially more of the complexity of the civil rights struggle. This book employs a methodology for analyzing not just the civil rights movement but other social movements and, indeed, social change in general.
A biography of George W. Bush, showing how he ignored his advisors to make key decisions himself--most in invading Iraq--and how these decisions were often driven by the President's deep religious faith.
The book gives a comprehensive review of the present state-of-the-art in ZnO R+D, including growth, doping, lattice dynamics, electric magnetic and optical properties. The emphasis is on the electric and optical properties, because this is the area where novel applications may be expected with highest promise. The book highlights not only the most recent results but gives both an overview of past research and of the present status -- not avoiding critical and controversial discussions of various aspects such as bank symmetries and laser processes. Intended to have long-lasting impact on ZnO R+D, this monograph addresses (post-)graduate students but also advanced scientists, who want to embark on ZnO research or are already involved, the present state of the art and assists them in avoiding duplication of old results (or mistakes).
