Feedback Control Theory
An excellent introduction to feedback control system design, this book offers a theoretical approach that captures the essential issues and can be applied to a wide range of practical problems. Its explorations of recent developments in the field emphasize the relationship of new procedures to classical control theory, with a focus on single input and output systems that keeps concepts accessible to students with limited backgrounds. The text is geared toward a single-semester senior course or a graduate-level class for students of electrical engineering. The opening chapters constitute a basic treatment of feedback design. Topics include a detailed formulation of the control design program, the fundamental issue of performance/stability robustness tradeoff, and the graphical design technique of loopshaping. Subsequent chapters extend the discussion of the loopshaping technique and connect it with notions of optimality. Concluding chapters examine controller design via optimization, offering a mathematical approach that is useful for multivariable systems.
Optimal Sampled-Data Control Systems
Among the many techniques for designing linear multivariable analogue controllers, the two most popular optimal ones are H2 and H-infinity optimization. The fact that most new industrial controllers are digital provides strong motivation for adapting or extending these techniques to digital control systems. This book, now available as a corrected reprint, attempts to do so. Part I presents two indirect methods of sampled-data controller design: These approaches include approximations to a real problem, which involves an analogue plant, continuous-time performance specifications, and a sampled-data controller. Part II proposes a direct attack in the continuous-time domain, where sampled-data systems are time-varying. The findings are presented in forms that can readily be programmed in, e.g., MATLAB.
Philosophers’ Walks
Nietzsche, Kierkegaard, Virginia Woolf, Samuel Taylor Coleridge, André Breton, Rousseau, Simone de Beauvoir: who could imagine a better group of walking companions? In this engaging and invigorating book, Bruce Baugh takes us on a philosophical tour, following in the footsteps and thoughts of some great philosophers and thinkers. How does walking reveal space and place and provide a heightened sense of embodied consciousness? Can walking in André Breton’s footsteps enable us to "remember" Breton’s experiences? A chapter on Sartre and Beauvoir investigates walking in relation to anxiety and our different ways of responding to our bodies. Walking in the Quantocks, Baugh seeks out the con...
Computer-assisted Reporting
An essential up-to-date resource for journalists and students who need to know how to use computers, data bases, and online resources for research and reporting.
Francis Schaeffer
Francis Schaeffer's view of humanity was that all human beings are created in the image of God-broken by the fall, but nonetheless created in the image of God, and are therefore creatures of great dignity and worth. It was the driving force behind his dealings with people, causing him to treat each person with significance and respect, and it was central to his view of how Christians should reach the world around them. Born from the first conference dedicated to his work and its continuing influence in our world, and selected from the best of the talks presented at that conference, this book offers the view that Francis Schaeffer's word to the Christian community is as relevant today, and maybe more so, than in his own lifetime.

Trees
Omnipresent and essential to life, trees have been underestimated by biologists. But in recent years, they have been the subject of scientific discoveries that have allowed us to see these oldest and largest members of the community of living beings in a new light. Capable of sensory perception, showing complex communication skills, living in symbiosis with many other species and influencing the climate, trees are equipped with unexpected faculties whose discovery confirms what indigenous, traditional and local communities had long acknowledged. Featuring works by contemporary artists including forest people, scientific imagery, films, photographs and sound installations, the exhibition at the Fondation Cartier pour l'art contemporain, Paris, strives to highlight the beauty, ingenuity and biological richness of trees, allowing us to see and hear these impressive protagonists of the living world that now find themselves also under increasing threat. Through paintings, drawings, photographs, scientific images, maps and texts by specialists, the catalogue published to accompany the exhibition invites the reader to dive into the fascinating and beautiful world of trees.
Freedom to Learn
The freedom of students to learn at university is being eroded by a performative culture that fails to respect their rights to engage and develop as autonomous adults. Instead, students are being restricted in how they learn, when they learn and what they learn by the so-called student engagement movement. Compulsory attendance registers, class contribution grading, group project work and reflective learning exercises based on expectations of self-disclosure and confession take little account of the rights of students or individual differences between them. This new hidden university curriculum is intolerant of students who may prefer to learn informally, are reticent, shy, or simply value t...
Recognising Faces
Each of us is able to recognise the faces of many hundreds if not thousands of people known to us. We recognise faces despite seeing them in different views and with changing expressions. From these varying patterns we somehow extract the invariant characteristics of an individual’s face, and usually remember why a face seems familiar, recalling where we know the person from and what they are called. In this book, originally published in 1988, the author describes the progress which has been made by psychologists towards understanding these perceptual and cognitive processes, and points to theoretical directions which may prove important in the future. Though emphasising theory, the book also addresses practical problems of eyewitness testimony, and discusses the relationship between recognising faces, and other aspects of face processing such as perceiving expressions and lipreading. The book was aimed primarily at a research audience, but would also interest advanced undergraduate students in vision and cognition.
Face Perception
Human faces are unique biological structures that convey a complex variety of important social messages. Even strangers can tell things from our faces – our feelings, our locus of attention, something of what we are saying, our age, sex and ethnic group, whether they find us attractive. In recent years there has been genuine progress in understanding how our brains derive all these different messages from faces and what can happen when one or other of the structures involved is damaged. Face Perception provides an up-to-date, integrative summary by two authors who have helped develop and shape the field over the past 30 years. It encompasses topics as diverse as the visual information our ...
