Model-Based Engineering with AADL

Model-Based Engineering with AADL

Peter H. Feiler; David P. Gluch

nidottu
Conventional build-then-test practices are making today’s embedded, software-reliant systems unaffordable to build. In response, more than thirty leading industrial organizations have joined SAE (formerly, the Society of Automotive Engineers) to define the SAE Architecture Analysis & Design Language (AADL) AS-5506 Standard, a rigorous and extensible foundation for model-based engineering analysis practices that encompass software system design, integration, and assurance. Using AADL, you can conduct lightweight and rigorous analyses of critical real-time factors such as performance, dependability, security, and data integrity. You can integrate additional established and custom analysis/specification techniques into your engineering environment, developing a fully unified architecture model that makes it easier to build reliable systems that meet customer expectations. Model-Based Engineering with AADL is the first guide to using this new international standard to optimize your development processes. Coauthored by Peter H. Feiler, the standard’s author and technical lead, this introductory reference and tutorial is ideal for self-directed learning or classroom instruction, and is an excellent reference for practitioners, including architects, developers, integrators, validators, certifiers, first-level technical leaders, and project managers. Packed with real-world examples, it introduces all aspects of the AADL notation as part of an architecture-centric, model-based engineering approach to discovering embedded software systems problems earlier, when they cost less to solve. Throughout, the authors compare AADL to other modeling notations and approaches, while presenting the language via a complete case study: the development and analysis of a realistic example system through repeated refinement and analysis. Part One introduces both the AADL language and core Model-Based Engineering (MBE) practices, explaining basic software systems modeling and analysis in the context of an example system, and offering practical guidelines for effectively applying AADL. Part Two describes the characteristics of each AADL element, including their representations, applicability, and constraints. The Appendix includes comprehensive listings of AADL language elements, properties incorporated in the AADL standard, and a description of the book’s example system.

Topical and up to date, Talons of the Eagle: Latin America, the United States, and the World, Fifth Edition, presents an eminent scholar's perspective on the interaction between global trends and inter-American affairs-a subject that has become crucially important in the current era. Rather than concentrating solely on U.S. policy, Peter H. Smith and Ana Covarrubias uniquely address the structural relationships between the two regions by focusing on internationalsystems, the distribution of power, and the perception and pursuit of national interests. Throughout, this provocative text casts light on such contemporary issues as economic integration, drug trafficking, undocumented migration, and the rise of Latin America's "new left." It also analyzes LatinAmerican reactions and responses to the U.S.-and to the rest of the world-in these complex and troubling times.

It provides a comprehensive analysis of the issues inherent in the move toward democracy-including elections, culture, representation, poverty, and criminality. Organized thematically, with a unique historical perspective, the book focuses on six paradigmatic case studies in the region: Argentina, Brazil, Chile, Mexico, Nicaragua, and Venezuela.
Vision and the Visual System

Vision and the Visual System

Peter H. Schiller; Edward J. Tehovnik

Oxford University Press Inc

Vision and the Visual System offers students, teachers, and researchers a rigorous, yet accessible account of how the brain analyzes the visual scene. Schiller and Tehovnik describe key aspects of visual perception while explaining the relationship between eye movements and the neural structures in the brain, which play a central role in how we process visual information. The book discusses various brain areas involved in processing information, focusing on the evolutionary origins and mechanics behind the several parallel pathways that compose the visual system. Later chapters explain how the nervous system processes the perception of color, motion, depth, and patterns. A variety of illusions are on display in Chapter 14, where the authors provide detailed explanations that deconstruct how the visual system operates to create them. The volume concludes with a discussion of recent attempts to build visual prosthetic devices for blind individuals, of which there are more than 40 million in the world. Vision and the Visual System is based on Professor Schiller's more than 40 years of experience teaching vision courses at MIT, and is tailored especially for college undergraduates and graduate students interested in visual perception and the operations of the visual system.

Under the Gun

In 1978, the Social and Demographic Research Institute of the University of Massachusetts, Amherst, received a grant from the National Institute of Justice to undertake a comprehensive review of the literature on weapons, crime, and violence in the United States. The purpose of the project is best described as a "sifting and winnowing" of the claims and counterclaims from both sides of the Great American Gun War - the perennial struggle in Ameri­can political life over what to do, if anything, about guns, about violence, and about crime. The review and analysis of the available studies consumed the better part of three years; the results of this work are contained in this volume.The intention of any review is to take stock of the available fund of knowledge in some topical area. Under the Gun is no different: our goal has been to glean from the volumes of previous studies those facts that, in our view, seem firmly and certainly established; those hypotheses that seem adequately supported by, or at least approximately consistent with, the best available research evidence; and those areas or topics about which, it seems, we need to know a lot more than we do. One of our major conclusions can be stated in advance: despite the large number of studies that have been done, many critically important questions have not been adequately researched, and some of them have not been examined at all.Much of the available research in the area of weapons and crime has been done by advocates for one or another policy position. As a consequence, the manifest intent of many "studies" is to persuade rather than to inform. We have tried to approach the topic from a purely agnostic point of view, treating as an open question what policies should be enacted with regard to gun, or crime, control. Thus, we have tried to judge each study on its own merits, on the basis of the routine standards normally applied to social-scientific research, and not on the basis of how effectively it argues for a particular policy direction. It would, of course, be presumptuous to claim that we have set aside all our own biases in conducting this study. Whether or not our treatment is fair and objective is clearly something for the reader, and not us, to decide.

The most accurate and comprehensive picture of homelessness to date, this study offers a powerful explanation of its causes, proposes short- and long-term solutions, and documents the striking contrasts between the homeless of the 1950s and 1960s and the contemporary homeless population, which is younger and contains more women, children, and blacks.
The Development of Behavioral States and the Expression of Emotions in Early Infancy
Peter H. Wolff, a world-renowned authority on infant behavior, helped lay the foundation for the field in the 1960s with his innovative studies of behavioral studies, motor coordination, smiling, and crying in infancy. Some twenty years later, as infancy studies have become increasingly specialized and fragmented, he calls for new theoretical perspectives and methods of investigation. Applying ethological methods used in field studies of animal behavior, Wolff first observes how babies behave in the "natural" ecology of their homes to catalog their species-typical behavioral repertory and then manipulates their behavior through informal experiments designed to examine functional significance. Wolff argues that a coherent psychobiological theory of early human development must begin with knowledge about the infant's behavioral repertory under free field conditions. Many current theories of human development begin instead with assumptions about the organization of behavior derived from studies of psychological function in the adult; moreover, they appeal to instincts, maturational programs, or genomes to explain the apparent lawfulness in the development of these behavioral categories. Such a priori explanations, Wolff contends, beg the whole question of development. As an alternative to theoretical metaphors that portray the infant as a closed system and suggests that development is controlled by prescient programs that anticipate the mature steady state, Wolff proposes a metaphor of the infant as an open, self-organizing system with partial, mutative mechanisms of development. Applying this metaphor, he addresses the essentially unsolved problem of how novel behavioral forms are induced during ontogenesis. Wolff presents a study of twenty-two infants who were observed for thirty hours each week in their homes during the first months after birth. He builds a week-by-week description of changes in behavioral states of wakefulness and examines how reversible state changes influence developmental transformations in social-affective behavior and sensori-motor intelligence. The observations and informal experiments emphasize expressions of emotion and the infant's changing relations to persons and things. Pointing out that movements are our only clue to what infants "feel" or "think," Wolff gives special emphasis to the systematic variations in spontaneous and environmentally evoked patterns of motor coordination as a function of behavioral state transitions. Of great importance to psychologists, psychiatrists, pediatricians, and students of development in general, The Development of Behavioral States and the Expression of Emotions in Early Infancy offers a major empirical, methodological, and theoretical rethinking of the subject to which Wolff has made outstanding contributions.
Expressive Forms in Brahms's Instrumental Music

Expressive Forms in Brahms's Instrumental Music

"This book is a substantial and timely contribution to Brahms studies. Its strategy is to focus on a single critical work, the C-Minor Piano Quartet, analyzing and interpreting it in great detail, but also using it as a stepping-stone to connect it to other central Brahms works in order to reach a new understanding of the composer's technical language and expressive intent. It is an original and worthy contribution on the music of a major composer." —Patrick McCreless Expressive Forms in Brahms's Instrumental Music integrates a wide variety of analytical methods into a broader study of theoretical approaches, using a single work by Brahms as a case study. On the basis of his findings, Smith considers how Brahms's approach in this piano quartet informs analyses of similar works by Brahms as well as by Beethoven and Mozart.

Why it matters that our relationship with nature is increasingly mediated and augmented by technology.Our forebears may have had a close connection with the natural world, but increasingly we experience technological nature. Children come of age watching digital nature programs on television. They inhabit virtual lands in digital games. And they play with robotic animals, purchased at big box stores. Until a few years ago, hunters could "telehunt"-shoot and kill animals in Texas from a computer anywhere in the world via a Web interface. Does it matter that much of our experience with nature is mediated and augmented by technology? In Technological Nature, Peter Kahn argues that it does, and shows how it affects our well-being.Kahn describes his investigations of children's and adults' experiences of cutting-edge technological nature. He and his team installed "technological nature windows" (50-inch plasma screens showing high-definition broadcasts of real-time local nature views) in inside offices on his university campus and assessed the physiological and psychological effects on viewers. He studied children's and adults' relationships with the robotic dog AIBO (including possible benefits for children with autism). And he studied online "telegardening" (a pastoral alternative to "telehunting").Kahn's studies show that in terms of human well-being technological nature is better than no nature, but not as good as actual nature. We should develop and use technological nature as a bonus on life, not as its substitute, and re-envision what is beautiful and fulfilling and often wild in essence in our relationship with the natural world.
German Unification in the European Context

German Unification in the European Context

Peter H. Merkl

Pennsylvania State University Press
1993
sidottu
The collapse of the Communist regime in East Germany and the subsequent unification of East and West Germany were events of extraordinary historical importance, the ramifications of which will take years to unfold. A leading U.S. expert on West German politics, Peter Merkl, had the good fortune to be a visiting professor at the University of Göttingen in 1990 and was able to witness this incredible transition firsthand. While teaching at the Free University in Berlin in 1991, Merkl enlisted the cooperation of a leading East German expert, Gert-Joachim Glaessner, to contribute a chapter on the GDR. The result is a work that offers a careful and comprehensive account of the process of unification and its implications for the future of European and international politics. Merkl begins by laying out the historical German Question and placing the divided state in the international context of the Cold War and its consequences. He then analyzes the generational differences between Germans over fifty who rallied to the challenge with enthusiasm and the less nationalistic younger generation who feared that the pursuit of unification would preempt such goals as a better life for West Germans and a livable environment. Gert-Joachim Glaessner describes in detail the spectacular unraveling of the East German communist regime that ultimately led to the fall of the Berlin Wall amidst the disintegration of the other Communist regimes, arguing that they did not fall on their own nor as a result of West German or Western initiatives alone. Merkl analyzes the process of political unification, the several elections of the year 1990, and the agreements made between East and West Germany. He also discusses the international objections to German unification and the many obstacles that were and will need to be overcome to make German unity a reality. He examines the attitudes of East and West Germans towards each other and their sense of national identity, the transformation of institutions and constitutions, and the immense problems and expense of rebuilding the East German infrastructure and economy and of privatizing state-owned operations. Finally, he maps out the international significance of the great changes of the post-Wall and post-Communist world that will define the future role of united Germany vis-à-vis Germany's neighbors, the European community, the United States, and the world. The book ends with a glimpse of how Germans envision themselves in the year 2000.

With its incorporation into architecture on a grand scale during the long nineteenth century, steel forever changed the way we perceive and inhabit buildings. In this book, Peter H. Christensen shows that even as architects and engineers were harnessing steel’s incredible properties, steel itself was busy transforming the natural world.Precious Metal explores this quintessentially modernist material—not for the heroic structural innovations it facilitated but for a deeper understanding of the role it played in the steady change of the earth. Focusing on the formative years of the architectural steel economy and on the corporate history of German steel titans Krupp and Thyssen, Christensen investigates the ecological interrelationship of artificial and natural habitats, mediated by steel. He traces steel through six distinct phases: birth, formation, display, dispersal, construction, and return. By following the life of steel from the collection of raw minerals to the distribution and disposal of finished products, Christensen challenges the traditional narrative that steel was simply the primary material responsible for architectural modernism.Based on the premise that building materials are as much a part of the natural world as they are of a building, this groundbreaking book rewrites an important chapter of architectural history. It will be welcomed by specialists in architectural history, nineteenth-century studies, environmental history, German studies, modernist studies, and the Anthropocene.

More than 180 pastors exited the Seventh-Day Adventist ministry in Australia and New Zealand between 1980 and 1988—a loss that is equivalent to 40 percent of the total annual Adventist ministerial workforce in those two countries. This volume examines the processes whereby conservative and committed sectarian pastors began to entertain doubts concerning the sectarian cause, questioned their occupational calling, and turned their backs on the ministry. Using the data gathered from in-depth interviews with 43 expastors and from other sources, the author develops detailed case study profiles, which highlight the personal, organizational, and social factors involved in their decision, and the types of experiences they associate with leaving the ministry. The first study of clergy fallout from a sectarian community, this volume makes a significant contribution to our understanding of exiting.

Early in the twentieth century, American socialists dared to dream of a future based on cooperation rather than competition. Socialism was a movement broad enough to encompass many points of view regarding the Red millennium. Socialist women, novelists, newspaper editors, and civil rights advocates, Christian socialists and Wobblies strained their eyes to see a future cooperative Commonwealth.Edward Bellamy portrayed socialism in the year 2000 for millions of readers in his novels as applied Christianity. Bellamy and other utopian novelists, including Jack London and Charlotte Perkins Gilman, tried to imagine the role of women in the expected new order. Christian socialists put their faith in a future Kingdom of God on earth that honored the ideas of Karl Marx. Radical newspaper editors in Kansas, Missouri, and Texas attempted to lay out the imagined transition to socialism to their readers in simple, straightforward language that made the goal seem readily obtainable. Mormons, disappointed in the changing nature of their faith, pondered a possible socialist future. Others, such as William English Walling, worked for a time ahead that was both socialist and colorblind. Challenging the notion that they had no concrete vision, this book of essays examines the many ways in which early 20th century American socialists imagined their future.
