Fault Diagnosis and Fault-Tolerant Control and Guidance for Aerospace demonstrates the attractive potential of recent developments in control for resolving such issues as flight performance, self protection and extended-life structures. Importantly, the text deals with a number of practically significant considerations: tuning, complexity of design, real-time capability, evaluation of worst-case performance, robustness in harsh environments, and extensibility when development or adaptation is required. Coverage of such issues helps to draw the advanced concepts arising from academic research back towards the technological concerns of industry. Initial coverage of basic definitions and ideas and a literature review gives way to a treatment of electrical flight control system failures: oscillatory failure, runaway, and jamming. Advanced fault detection and diagnosis for linear and linear-parameter-varying systems are described. Lastly recovery strategies appropriate to remaining actuator/sensor/communications resources are developed. The authors exploit experience gained in research collaboration with academic and major industrial partners to validate advanced fault diagnosis and fault-tolerant control techniques with realistic benchmarks or real-world aeronautical and space systems. Consequently, the results presented in Fault Diagnosis and Fault-Tolerant Control and Guidance for Aerospace, will be of interest in both academic and aerospatial-industrial milieux.
In the wake of Stalin’s death in 1953, the Soviet Union entered a period of relative openness known as the Thaw. Soviet citizens took advantage of the new opportunities to meditate on the nation’s turbulent history, from the Bolshevik Revolution, to the Terror, to World War II. Perhaps the most influential of these conversations took place in and around Novyi mir (New World), the most respected literary journal in the country. In The Readers of Novyi Mir, Denis Kozlov shows how the dialogue between literature and readers during the Thaw transformed the intellectual life and political landscape of the Soviet Union. Powerful texts by writers like Solzhenitsyn, Pasternak, and Ehrenburg led thousands of Novyi mir’s readers to reassess their lives, entrenched beliefs, and dearly held values, and to confront the USSR’s history of political violence and social upheaval. And the readers spoke back. Victims and perpetrators alike wrote letters to the journal, reexamining their own actions and bearing witness to the tragedies of the previous decades. Kozlov’s insightful treatment of these confessions, found in Russian archives, and his careful reading of the major writings of the period force today’s readers to rethink common assumptions about how the Soviet people interpreted their country’s violent past. The letters reveal widespread awareness of the Terror and that literary discussion of its legacy was central to public life during the late Soviet decades. By tracing the intellectual journey of Novyi mir’s readers, Kozlov illuminates how minds change, even in a closed society.
This book is devoted to the phenomenon of removal of people declared "public enemies" from group photographs in Stalin’s Russia. The book is based on long-term empirical research in Russian archives and includes 57 photographs that are exceptional in terms of historical interest: all these images bear traces of editing in the form of various marks, such as blacking-out, excisions or scratches. The illustrative materials also include a group of photographs with inscriptions left by officers of Stalin’s secret police, the NKVD. To approach this extensive visual material, Denis Skopin draws on a wealth of Stalin-era written sources: memoirs, diaries and official documents. He argues that this kind of political iconoclasm cannot be confused with censorship nor vandalism. The practice in question is more harrowing and morally twisted, for in most cases the photos were defaced by those who were part of victim’s intimate circle: his/her colleagues, friends or even close family members. The book will be of interest to scholars working in history of photography, art history, visual culture, Russian studies and Russian history and politics.
Hockey My Door to Europe details the author’s personal - sometimes harrowing - experiences covering international hockey, especially behind the Iron Curtain, including the start of youth hockey exchanges between Canada and communist countries. The book also provides an in-depth view of the following events: - The author’s detainment by the Czechoslovak secret police in 1983; - The nuclear plant explosion in Chernobyl, which occurred during the 1986 World Championship in Moscow; - The defection of Soviet hockey star Alexander Mogilny following the 1989 World Championship in Stockholm; - The fall of the Berlin Wall, which took place in November of 1989 while the author was in Moscow; - The uprising in Kiev, Ukraine, which occurred during the 2014 Winter Olympics in Sochi, Russia, leading to Russia’s annexation of Crimea.
The period from Stalin’s death in 1953 to the end of the 1960s marked a crucial epoch in Soviet history. Though not overtly revolutionary, this era produced significant shifts in policies, ideas, language, artistic practices, daily behaviours, and material life. It was also during this time that social, cultural, and intellectual processes in the USSR began to parallel those in the West (and particularly in Europe) as never before. This volume examines in fascinating detail the various facets of Soviet life during the 1950s and 1960s, a period termed the ‘Thaw.’ Featuring innovative research by historical, literary, and film scholars from across the world, this book helps to answer fundamental questions about the nature and ultimate fortune of the Soviet order – both in its internal dynamics and in its long-term and global perspectives.
This monograph presents some existing and new results on analysis and design of finite-time and fixed-time converging systems. Two main groups of approaches for analysis/synthesis of this kind of convergence, Lyapunov functions and the theory of homogeneous systems, are considered.The authors focus on the dynamics described by ordinary differential equations, time-delay models and partial differential equations. Some popular control and estimation algorithms, which possess accelerated converge rates, are also reviewed. Finally, the issues of discretization of finite-/fixed-time converging systems are discussed.Divided into 3 parts, this monograph provides the reader with a complete and accessible review of the topic. In the first part, the definitions of the different finite-/fixed-time stability properties are given together with their characterizations via the Lyapunov function approach. In the second part, several stabilization algorithms for linear and nonlinear systems are formalized, which are based on the implicit Lyapunov function approach. In the third part, the issues of discretization of finite-/fixed-time stable systems are discussed, with a special attention to the solutions obtained with the implicit Lyapunov function method. Finally, the accelerated converge concepts are presented for systems described by time-delay and partial differential equations.This monograph is an excellent introduction to the complex field of Finite-Time Stability Tools. It enables the reader to synthesize the important concepts and further their own research in the area.
