David Ayerst

Originally published in 1985. One of the most distinguished editors in the history of British journalism, J. L. Garvin created the Sunday newspaper as we now know it. His career at the Observer spanned the golden age of the British press when newspapers had a powerful influence on political affairs. Like the other great editors of the first half of the twentieth century Garvin clashed with his proprietors. He liked to contrast ‘Responsible Editorship’ with ‘Austensible Editorship’ where the editor took his political orders from the owners. He passionately believed that the readers of any newspaper worth buying had a right to know what the editor himself thought about any important matter. This was the essence of an implied contract, the basis of trust between paper and the reader. It was Garvin’s energy and integrity which transformed the Observer into a major force in the British press so that long before his death most respectable middle class families would have hesitated to admit they had not seen the Observer. This first substantial biography of Garvin of the Observer will be of interest to all students of modern political history and of the press in contemporary society.

THE SUNDAY TIMES HISTORY BOOK OF THE YEAR 2017 'A beautiful and thoughtful exploration of the role of the horse in creating our world' James Rebanks 'Scintillating, exhilarating ... you have never read a book like it ... a new way of considering history' Observer The relationship between horses and humans is an ancient, profound and complex one. For millennia horses provided the strength and speed that humans lacked. How we travelled, farmed and fought was dictated by the needs of this extraordinary animal. And then, suddenly, in the 20th century the links were broken and the millions of horses that shared our existence almost vanished, eking out a marginal existence on race-tracks and pony clubs. Farewell to the Horse is an engaging, brilliantly written and moving discussion of what horses once meant to us. Cities, farmland, entire industries were once shaped as much by the needs of horses as humans. The intervention of horses was fundamental in countless historical events. They were sculpted, painted, cherished, admired; they were thrashed, abused and exposed to terrible danger. From the Roman Empire to the Napoleonic Empire every world-conqueror needed to be shown on a horse. Tolstoy once reckoned that he had cumulatively spent some nine years of his life on horseback. Ulrich Raulff's book, a bestseller in Germany, is a superb monument to the endlessly various creature who has so often shared and shaped our fate.

Reese Witherspoon

Academy Award–winning actress, producer, and entrepreneur Reese Witherspoon invites you into her world, where she infuses the southern style, parties, and traditions she loves with contemporary flair and charm. Reese Witherspoon’s grandmother Dorothea always said that a combination of beauty and strength made southern women “whiskey in a teacup.” We may be delicate and ornamental on the outside, she said, but inside we’re strong and fiery. Reese’s southern heritage informs her whole life, and she loves sharing the joys of southern living with practically everyone she meets. She takes the South wherever she goes with bluegrass, big holiday parties, and plenty of Dorothea’s fried chicken. It’s reflected in how she entertains, decorates her home, and makes holidays special for her kids—not to mention how she talks, dances, and does her hair (in these pages, you will learn Reese’s fail-proof, only slightly insane hot-roller technique). Reese loves sharing Dorothea’s most delicious recipes as well as her favorite southern traditions, from midnight barn parties to backyard bridal showers, magical Christmas mornings to rollicking honky-tonks. It’s easy to bring a little bit of Reese’s world into your home, no matter where you live. After all, there’s a southern side to every place in the world, right?

download ebook frequency-shaped and observer-based discrete-time sliding mode control pdf epub

Axaykumar Mehta,Bijnan Bandyopadhyay

It is well established that the sliding mode control strategy provides an effective and robust method of controlling the deterministic system due to its well-known invariance property to a class of bounded disturbance and parameter variations. Advances in microcomputer technologies have made digital control increasingly popular among the researchers worldwide. And that led to the study of discrete-time sliding mode control design and its implementation. This brief presents, a method for multi-rate frequency shaped sliding mode controller design based on switching and non-switching type of reaching law. In this approach, the frequency dependent compensator dynamics are introduced through a frequency-shaped sliding surface by assigning frequency dependent weighing matrices in a linear quadratic regulator (LQR) design procedure. In this way, the undesired high frequency dynamics or certain frequency disturbance can be eliminated. The states are implicitly obtained by measuring the output at a faster rate than the control. It is also known that the vibration control of smart structure is a challenging problem as it has several vibratory modes. So, the frequency shaping approach is used to suppress the frequency dynamics excited during sliding mode in smart structure. The frequency content of the optimal sliding mode is shaped by using a frequency dependent compensator, such that a higher gain can be obtained at the resonance frequencies. The brief discusses the design methods of the controllers based on the proposed approach for the vibration suppression of the intelligent structure. The brief also presents a design of discrete-time reduced order observer using the duality to discrete-time sliding surface design. First, the duality between the coefficients of the discrete-time reduced order observer and the sliding surface design is established and then, the design method for the observer using Riccati equation is explained. Using the proposed method, the observer for the Power System Stabilizer (PSS) for Single Machine Infinite Bus (SMIB) system is designed and the simulation is carried out using the observed states. The discrete-time sliding mode controller based on the proposed reduced order observer design method is also obtained for a laboratory experimental servo system and verified with the experimental results.

Wiley Cash

Named a Best Book of 2017 by the Chicago Public Library and the American Library Association “Wiley Cash reveals the dignity and humanity of people asking for a fair shot in an unfair world.” - Christina Baker Kline, author of A Piece of the World and Orphan Train The New York Times bestselling author of the celebrated A Land More Kind Than Home and This Dark Road to Mercy returns with this eagerly awaited new novel, set in the Appalachian foothills of North Carolina in 1929 and inspired by actual events. The chronicle of an ordinary woman’s struggle for dignity and her rights in a textile mill, The Last Ballad is a moving tale of courage in the face of oppression and injustice, with the emotional power of Ron Rash’s Serena, Dennis Lehane’s The Given Day, and the unforgettable films Norma Rae and Silkwood. Twelve times a week, twenty-eight-year-old Ella May Wiggins makes the two-mile trek to and from her job on the night shift at American Mill No. 2 in Bessemer City, North Carolina. The insular community considers the mill’s owners—the newly arrived Goldberg brothers—white but not American and expects them to pay Ella May and other workers less because they toil alongside African Americans like Violet, Ella May’s best friend. While the dirty, hazardous job at the mill earns Ella May a paltry nine dollars for seventy-two hours of work each week, it’s the only opportunity she has. Her no-good husband, John, has run off again, and she must keep her four young children alive with whatever work she can find. When the union leaflets begin circulating, Ella May has a taste of hope, a yearning for the better life the organizers promise. But the mill owners, backed by other nefarious forces, claim the union is nothing but a front for the Bolshevik menace sweeping across Europe. To maintain their control, the owners will use every means in their power, including bloodshed, to prevent workers from banding together. On the night of the county’s biggest rally, Ella May, weighing the costs of her choice, makes up her mind to join the movement—a decision that will have lasting consequences for her children, her friends, her town—indeed all that she loves. Seventy-five years later, Ella May’s daughter Lilly, now an elderly woman, tells her nephew about his grandmother and the events that transformed their family. Illuminating the most painful corners of their history, she reveals, for the first time, the tragedy that befell Ella May after that fateful union meeting in 1929. Intertwining myriad voices, Wiley Cash brings to life the heartbreak and bravery of the now forgotten struggle of the labor movement in early twentieth-century America—and pays tribute to the thousands of heroic women and men who risked their lives to win basic rights for all workers. Lyrical, heartbreaking, and haunting, this eloquent novel confirms Wiley Cash’s place among our nation’s finest writers.

Zahid Bukhari

THE collection of papers in this volume documents the study of Islam in American Universities. Over the last few decades the United States has seen significant growth in the study of Islam and Islamic societies in institutions of higher learning fueled primarily by events including economic relations of the U.S. with Muslim countries, migration of Muslims into the country, conversion of Americans to Islam, U.S. interests in Arab oil resources, involvement of Muslims in the American public square, and the tragic events of 9/11. Although there is increasing recognition that the study of Islam and the role of Muslims is strategically essential in a climate of global integration, multiculturalism, and political turmoil, nevertheless, the state of Islamic Studies in America is far from satisfactory. The issue needs to be addressed, particularly as the need for intelligent debate and understanding is continuously stifled by what some have termed an “Islam industry” run primarily by fly-by journalists, think tank pundits, and cut-and-paste “experts.”

America, it's time to wake up and realize what the war against the family has done to our kids. My hope is that, in addition to telling stories about kids who have shared our home, Front Line Observer may be your wake up call.Front Line Observer is a mixture of stories and lessons learned from 29 years of working and living with kids. Included in these 29 years are 24 years of residential work with kids in foster care.I tell some stories about the kids, and share what my wife and I have learned about why kids are removed from their parents or are placed in foster care. I will tell about the damage done to our children by the disintrigation of the family in our society and by those who do not understand the value of our children. I will show how those in our society who are willing to destroy the family are hurting our children. I will share what we have seen about how the casualties in the war against the family are our children.Kids who come into foster care and into our home almost never come from familiesconsisting ofparents who are a mom and dad who aremarried and together. Instead, they come from parents who have chosen "alternatives" to the traditional family or to have counterfeit "families". In particular, I will confront fathers whorefuse toaccept responsibility for their children and families, and present ideas on how we can motivate these fathers to take responsibility for their children. I will also present ideasfor anyone who wants to help children who are hurting from an absent dad, or who wants to join the battle in the fight for the family.

Helmut Wiedemann

Particle Accelerator Physics covers the dynamics of relativistic particle beams, basics of particle guidance and focusing, lattice design, characteristics of beam transport systems and circular accelerators. Particle-beam optics is treated in the linear approximation including sextupoles to correct for chromatic aberrations. Perturbations to linear beam dynamics are analyzed in detail and correction measures are discussed, while basic lattice design features and building blocks leading to the design of more complicated beam transport systems and circular accelerators are studied. Characteristics of synchrotron radiation and quantum effects due to the statistical emission of photons on particle trajectories are derived and applied to determine particle-beam parameters. The discussions specifically concentrate on relativistic particle beams and the physics of beam optics in beam transport systems and circular accelerators such as synchrotrons and storage rings. This book forms a broad basis for further, more detailed studies of nonlinear beam dynamics and associated accelerator physics problems, discussed in the subsequent volume.

download ebook observer-based fault estimation and accomodation for dynamic systems pdf epub

Ke Zhang,Bin Jiang,Peng Shi

Due to the increasing security and reliability demand of actual industrial process control systems, the study on fault diagnosis and fault tolerant control of dynamic systems has received considerable attention. Fault accommodation (FA) is one of effective methods that can be used to enhance system stability and reliability, so it has been widely and in-depth investigated and become a hot topic in recent years. Fault detection is used to monitor whether a fault occurs, which is the first step in FA. On the basis of fault detection, fault estimation (FE) is utilized to determine online the magnitude of the fault, which is a very important step because the additional controller is designed using the fault estimate. Compared with fault detection, the design difficulties of FE would increase a lot, so research on FE and accommodation is very challenging. Although there have been advancements reported on FE and accommodation for dynamic systems, the common methods at the present stage have design difficulties, which limit applications of respective design approaches. Therefore, the problems of FE and accommodation are needed to be further studied. This book considers the theory and technology of FE and accommodation for dynamic systems, and establishes a systemic and comprehensive framework of FE and accommodation for continuous/discrete-time systems.

Esther Harriott

Since 1900, the average life expectancy in the developed world has almost doubled, from 45 to 80. “We are almost a new species,” declared the English writer V.S. Pritchett, while pointing out that this means “most of us have to face the prospect of a long old age before we die.” Pritchett is one of five great writers—along with Stanley Kunitz, Doris Lessing, Mavis Gallant and Russell Baker—whose novels, short stories, poems and essays about old age, written in old age, are examined in this book. Born between 1900 (Pritchett) and 1925 (Baker), these writers are members of the first generation of the 20th century, and of the first generation of writers able to write about old age from experience. In their later works we read about growing old as reported by the old, not as imagined by the young and middle-aged. They wrote about old age not as a discrete stage of life, but as a continuation—another context in which to pursue the themes of their earlier poems, novels, stories and essays. And those who had written about love—a central theme of fiction and poetry—now wrote about love in old age.

Robin Fox

Robin Fox, one of the preeminent anthropologists of our time, takes us on an exuberant personal, intellectual and cultural journey through the 1930s to the 1970s. This is a personal, historical, intellectual journey, one that is at once intriguing, hilarious, and moving. Like Browning's Sordello (who recurs throughout the book), Fox is telling the story of "the development of a soul." Fox's method is to depend entirely on memory to select the people, events, and ideas that have driven him towards what was called at the time a "revolution in the social sciences." This revolution was the founding of the biosocial, or what came to be called the sociobiological, movement in the study of human behavior. It was a long road peppered with strange events, brain-bending ideas, odd adventures, dangers and sorrows, and a cast of lively, often eccentric characters.Fox describes himself as an observer of a series of endings: the last gasps of now extinct ways of life. He witnessed the last of the old steam and horse-powered northern wool towns of the industrial revolution and the pre-industrial Hardy countryside of southern England. He saw the ancient grammar schools before their destruction by doctrinaire socialism; the old LSE when it was still an international family, not just a big college; the brave but failed experiment that was Talcott Parsons' Social Relations Department. In the United States, he experienced the innocent but troubled America of the 1950s and the last gasp of traditional Indian life in New Mexico. He lived in genteel Jane Austen England in Devon and experienced peasant-crofter life in the Irish islands.Participant Observer is a report from the cultural and social battlefront, seen through the personal lens of a combatant. Fox has given us a kind of Cook's Tour through the ideas and intellectual movements of mid-century, when the world changed and the foundations of the twenty-first century were set. It is the history of an education by a narrator in love with learning.

Robert Winder

It is often assumed that the national identity must be a matter of values and ideas. But in Robert Winder's brilliantly-written account it is a land built on a lucky set of natural ingredients: the island setting that made it maritime; the rain that fed the grass that nourished the sheep that provided the wool, and the wheat fields that provided its cakes and ale. Then came the seams of iron and coal that made it an industrial giant. In Bloody Foreigners Robert Winder told the rich story of immigration to Britain. Now, in The Last Wolf, he spins an English tale. Travelling the country, he looks for its hidden springs not in royal pageantry or politics, but in landscape and history. Medieval monks with their flocks of sheep . . . cathedrals built by wool . . . the first shipment of coal to leave Newcastle . . . marital contests on a village green . . . mock-Tudor supermarkets - the story is studded with these and other English things. And it starts by looking at a very important thing England did not have: wolves.

download ebook observability and observation in physical science pdf epub

Peter Kosso

The concept of observability of entities in physical science is typically analyzed in terms of the nature and significance of a dichotomy between observables and unobservables. In this book, however, this categorization is resisted and observability is analyzed in a descriptive way in terms of the information which one can receive through interaction with objects in the world. The account of interaction and the transfer of information is done using applicable scientific theories. In this way the question of observability of scientific entities is put to science itself. Several examples are presented which show how this interaction-information account of observability is done. It is demonstrated that observability has many dimensions which are in general orthogonal. The epistemic significance of these dimensions is explained. This study is intended primarily as a method for understanding problems of observability rather than as a solution to those problems. The important issue of scientific realism and its relation to observability, however, demands attention. Hence, the implication of the interaction-information account for realism is drawn in terms of the epistemic significance of the dimensions of observability. This amounts to specifying what it is about good observations that make them objective evidence for scientific theories.

For the past five decades the Texas Observer has been an essential voice in Texas culture and politics, championing honest government, civil rights, labor, and the environment, while providing a platform for many of the state’s most passionate and progressive voices. Included are ninety-one selections from Roy Bedichek, Lou Dubose, Ronnie Dugger, Dagoberto Gilb, Jim Hightower, Molly Ivins, Larry McMurtry, Maury Maverick Jr., Willie Morris, Debbie Nathan, and others. To mark the Observer’s fiftieth anniversary, Char Miller has selected a cross section of the best work to appear in its pages. Not only does the collection pay homage to an important alternative voice in Texas journalism, it also serves as a progressive chronicle of a half-century of life in the Lone Star State—a state that has spawned three presidents in the last forty years. If Texas is, as some say, a crucible for national politics, then Fifty Years of the Texas Observer can be read as a casebook for issues that concern citizens in all fifty states. Molly Ivins's foreword gives historical background for the Observer and sets the stage for the book.

download ebook why would domestic election observers endorse unfree elections? pdf epub

Kathrin Baumann

Bachelor Thesis from the year 2016 in the subject Politics - Political Systems - General and Comparisons, grade: 1,3, University of Mannheim (School of Social Sciences), language: English, abstract: Domestic election observers sometimes endorse elections even though those cannot be characterized as free and fair. Based on the studies of Judith Kelley (2009: 2010), I examine what causes this endorsement. My argument is that domestic observers are more likely to endorse unfree elections if pre-election violence and improvement took place. The dataset used to answer the research question is a new one, based on domestic observer reports from the GNDEM, Freedom House, the PTS and the V-dem 6.0 dataset. By doing logistic regression, I find out that some reasons for endorsement are similar for both domestic and international observers. It is puzzling that domestic monitors accept fraudulent elections because it affects their credibility and reduces their influence as they may be viewed as unreliable. For international observers, various reasons for this phenomenon have been identified but domestic observers have received little attention so far. Yet, domestic organizations are different from international ones in terms of structure and environment, which raises the question to what extent reasons for endorsement can be similar. Therefore, it is necessary to take a deeper look at local observers in order to fill a gap in the literature. Moreover, a better understanding is needed in order to improve domestic monitoring, the quality of democracy promotion, and to avoid the unwanted effect of stabilizing non-democratic regimes. Democratization must come from the inside in order to be successful and domestic observers may give the crucial incentive; however, only credible monitors can make a difference. Therefore, my research question will be the following: why would domestic election observers endorse unfree elections?

Many people believe in the Power of Positive Thinking, but no one has succeeded in credibly explaining how mere thoughts can tangibly influence future occurrences. To explain the connection, this book presents a new paradigm of nature and couples it with a convincing explanation of how our right brain hemispheres have a unique ability to tap into the hidden domain of the metaphysical. To support this premise, the reader is lightly exposed to the divergent worlds of physics and metaphysics and is then introduced to a new view of nature that undeniably links mind to matter. Important to its charge, the new perspective makes the case that the future can only be created with thoughts. In the final analysis, the author brings his readers through the necessary steps to put this knowledge to work to help them create their own realities.

"Taka iimura has been making films since the early 1960s. His work has gone through a series of relatively clear, consistent developments: from 1962 to 1968, iimura was largely involved with surreal imagery, with eroticism, and with social criticism; from 1968 through 1971, he continued to use photographic imagery, but worked with it in increasingly formal ways; from 1972 until 1978, he devoted himself very largely to a series of minimalist explorations of time and space. During the years since, iimura has been more fully involved with video than with film." --Scott MacDonald "Although Taka was and continues to be an active part of the New York avant-garde scene, he always remained an enigmatic, mysterious presence, pursuing his own unique route through the very center of the avant-garde cinema. While the intensity and the fire of the American avant-garde film movement inspired him and attracted him, his Japanese origins contributed decisively to his uncompromising explorations of cinema's minimalist and conceptualist possibilities. He has explored this direction of cinema in greater depth than anyone else." -- Jonas Mekas

Rafael Martínez-Guerra,Juan Luis Mata-Machuca

The high reliability required in industrial processes has created the necessity of detecting abnormal conditions, called faults, while processes are operating. The term fault generically refers to any type of process degradation, or degradation in equipment performance because of changes in the process's physical characteristics, process inputs or environmental conditions. This book is about the fundamentals of fault detection and diagnosis in a variety of nonlinear systems which are represented by ordinary differential equations. The fault detection problem is approached from a differential algebraic viewpoint, using residual generators based upon high-gain nonlinear auxiliary systems (‘observers’). A prominent role is played by the type of mathematical tools that will be used, requiring knowledge of differential algebra and differential equations. Specific theorems tailored to the needs of the problem-solving procedures are developed and proved. Applications to real-world problems, both with constant and time-varying faults, are made throughout the book and include electromechanical positioning systems, the Continuous Stirred Tank Reactor (CSTR), bioreactor models and belt drive systems, to name but a few.
