OPC Unified Architecture by Wolfgang Mahnke,Stefan-Helmut Leitner,Matthias Damm Pdf

Motivation for This Book The OPC Foundation provides specifications for data exchange in industrial au- mation. There is a long history of COM/DCOM-based specifications, most pro- nent OPC Data Access (DA), OPC Alarms and Events (A&E), and OPC Historical Data Access (HDA), which are widely accepted in the industry and implemented by almost every system targeting industrial automation. Now the OPC Foundation has released a new generation of OPC specifications called OPC Unified Architecture (OPC UA). With OPC UA, the OPC Foundation fulfills a technology shift from the retiring COM/DCOM technology to a servi- oriented architecture providing data in a platform-independent manner via Web Services or its own optimized TCP-based protocol. OPC UA unifies the previous specifications into one single address space capable of dealing with current data, alarms and events and the history of current data as well as the event history. A remarkable enhancement of OPC UA is the Address Space Model by which v- dors can expose a rich and extensible information model using object-oriented techniques. OPC UA scales well from intelligent devices, controllers, DCS, and SCADA systems up to MES and ERP systems. It also scales well in its ability to provide information; on the lower end, a model similar to Classic OPC can be used, providing only base information, while at the upper end, highly sophisticated models can be described, providing a large amount of metadata including complex type hierarchies.

Putin Country by Anne Garrels Pdf

Short-listed for the Pushkin House Russian Book Prize More than twenty years ago, the NPR correspondent Anne Garrels first visited Chelyabinsk, a gritty military-industrial center a thousand miles east of Moscow. The longtime home of the Soviet nuclear program, the Chelyabinsk region contained beautiful lakes, shuttered factories, mysterious closed cities, and some of the most polluted places on earth. Garrels’s goal was to chart the aftershocks of the U.S.S.R.’s collapse by traveling to Russia’s heartland. Returning again and again, Garrels found that the area’s new freedoms and opportunities were exciting but also traumatic. As the economic collapse of the early 1990s abated, the city of Chelyabinsk became richer and more cosmopolitan, even as official corruption and intolerance for minorities grew more entrenched. Sushi restaurants proliferated; so did shakedowns. In the neighboring countryside, villages crumbled into the ground. Far from the glitz of Moscow, the people of Chelyabinsk were working out their country’s destiny, person by person. In Putin Country, Garrels crafts an intimate portrait of Middle Russia. We meet upwardly mobile professionals, impassioned activists who champion the rights of orphans and disabled children, and ostentatious mafiosi. We discover surprising subcultures, such as a vibrant underground gay community and a circle of determined Protestant evangelicals. And we watch doctors and teachers trying to cope with inescapable payoffs and institutionalized negligence. As Vladimir Putin tightens his grip on power and war in Ukraine leads to Western sanctions and a lower standard of living, the local population mingles belligerent nationalism with a deep ambivalence about their country’s direction. Through it all, Garrels sympathetically charts an ongoing identity crisis. In the aftermath of the Soviet Union, what is Russia? What kind of pride and cohesion can it offer? Drawing on close friendships sustained over many years, Garrels explains why Putin commands the loyalty of so many Russians, even those who decry the abuses of power they regularly encounter. Correcting the misconceptions of Putin’s supporters and critics alike, Garrels’s portrait of Russia’s silent majority is both essential and engaging reading at a time when cold war tensions are resurgent.

Unreconciled by Jesse Wente Pdf

NATIONAL BESTSELLER SHORTLISTED for the 2022 Rakuten Kobo Emerging Writer Prize A GLOBE AND MAIL BEST BOOK OF THE YEAR "Unreconciled is one hell of a good book. Jesse Wente’s narrative moves effortlessly from the personal to the historical to the contemporary. Very powerful, and a joy to read." —Thomas King, author of The Inconvenient Indian and Sufferance A prominent Indigenous voice uncovers the lies and myths that affect relations between white and Indigenous peoples and the power of narrative to emphasize truth over comfort. Part memoir and part manifesto, Unreconciled is a stirring call to arms to put truth over the flawed concept of reconciliation, and to build a new, respectful relationship between the nation of Canada and Indigenous peoples. Jesse Wente remembers the exact moment he realized that he was a certain kind of Indian--a stereotypical cartoon Indian. He was playing softball as a child when the opposing team began to war-whoop when he was at bat. It was just one of many incidents that formed Wente's understanding of what it means to be a modern Indigenous person in a society still overwhelmingly colonial in its attitudes and institutions. As the child of an American father and an Anishinaabe mother, Wente grew up in Toronto with frequent visits to the reserve where his maternal relations lived. By exploring his family's history, including his grandmother's experience in residential school, and citing his own frequent incidents of racial profiling by police who'd stop him on the streets, Wente unpacks the discrepancies between his personal identity and how non-Indigenous people view him. Wente analyzes and gives voice to the differences between Hollywood portrayals of Indigenous peoples and lived culture. Through the lens of art, pop culture, and personal stories, and with disarming humour, he links his love of baseball and movies to such issues as cultural appropriation, Indigenous representation and identity, and Indigenous narrative sovereignty. Indeed, he argues that storytelling in all its forms is one of Indigenous peoples' best weapons in the fight to reclaim their rightful place. Wente explores and exposes the lies that Canada tells itself, unravels "the two founding nations" myth, and insists that the notion of "reconciliation" is not a realistic path forward. Peace between First Nations and the state of Canada can't be recovered through reconciliation--because no such relationship ever existed.

You Don’t Belong Here by Elizabeth Becker Pdf

The long-buried story of three extraordinary female journalists who permanently shattered the barriers to women covering war Kate Webb, an Australian iconoclast, Catherine Leroy, a French daredevil photographer, and Frances FitzGerald, a blue-blood American intellectual, arrived in Vietnam with starkly different life experiences but one shared purpose: to report on the most consequential story of the decade. At a time when women were considered unfit to be foreign reporters, Frankie, Catherine and Kate challenged the rules imposed on them by the military, ignored the belittlement of their male peers, and ultimately altered the craft of war reportage for generations. In You Don’t Belong Here, Elizabeth Becker uses these women’s work and lives to illuminate the Vietnam War from the 1965 American buildup, the expansion into Cambodia, and the American defeat and its aftermath. Arriving herself in the last years of the war, Becker writes as a historian and a witness of the times. What emerges is an unforgettable story of three journalists forging their place in a land of men, often at great personal sacrifice. Deeply reported and filled with personal letters, interviews, and profound insight, You Don’t Belong Here fills a void in the history of women and of war. ‘A riveting read with much to say about the nature of war and the different ways men and women correspondents cover it. Frank, fast-paced, often enraging, You Don’t Belong Here speaks to the distance travelled and the journey still ahead.’ —Geraldine Brooks, Pulitzer Prize–winning author of March, former Wall Street Journal foreign correspondent ‘Riveting, powerful and transformative, Elizabeth Becker’s You Don’t Belong Here tells the stories of three astonishing women. This is a timely and brilliant work from one of our most extraordinary war correspondents.’ —Madeleine Thien, Booker Prize finalist and author of Do Not Say We Have Nothing

We Have Always Been Here by Samra Habib Pdf

CANADA READS 2020 WINNER NATIONAL BESTSELLER 2020 LAMBDA LITERARY AWARD WINNER How do you find yourself when the world tells you that you don't exist? Samra Habib has spent most of her life searching for the safety to be herself. As an Ahmadi Muslim growing up in Pakistan, she faced regular threats from Islamic extremists who believed the small, dynamic sect to be blasphemous. From her parents, she internalized the lesson that revealing her identity could put her in grave danger. When her family came to Canada as refugees, Samra encountered a whole new host of challenges: bullies, racism, the threat of poverty, and an arranged marriage. Backed into a corner, her need for a safe space--in which to grow and nurture her creative, feminist spirit--became dire. The men in her life wanted to police her, the women in her life had only shown her the example of pious obedience, and her body was a problem to be solved. So begins an exploration of faith, art, love, and queer sexuality, a journey that takes her to the far reaches of the globe to uncover a truth that was within her all along. A triumphant memoir of forgiveness and family, both chosen and not, We Have Always Been Here is a rallying cry for anyone who has ever felt out of place and a testament to the power of fearlessly inhabiting one's truest self.

A Red Line in the Sand by David A. Andelman Pdf

A longtime CNN columnist astutely combines history and global politics to help us better understanding the exploding number of military, political, and diplomatic crises around the globe. The riveting and illuminating behind-the-scenes stories of the world's most intense “red lines," from diplomatic and military challenges at particular turning points in history to the ones that set the tone of geopolitics today. Whether it was the red line in Munich that led to the start of the Second World War, to the red lines in the South China Sea, the Korean Peninsula, Syria and the Middle East. As we traverse the globe, Andelman uses original documentary research, previously classified material, and interviews with key players, to help us understand the growth, the successes and frequent failures that have shaped our world today. Andelman provides not just vivid historical context, but a political anatomy of these red lines. How might their failures be prevented going forward? When and how can such lines in the sand help preserve peace rather than tempt conflict? A Red Line in the Sand is a vital examination of our present and the future—where does diplomacy end and war begin? It is an object lesson of tantamount importance to every leader, diplomat, citizen, and voter. As America establishes more red lines than it has pledged to defend, every American should understand the volatile atmosphere and the existential stakes of the red web that encompasses the globe.
