Available in PDF, EPUB and Kindle. Book excerpt: “We got to talking”—so David Antin begins the introduction to Radical Coherency, embarking on the pursuit that has marked much of his breathless, brilliantly conversational work. For the past forty years, whether spoken under the guise of performance artist or poet, cultural explorer or literary critic, Antin’s innovative observations have helped us to better understand everything from Pop to Postmodernism. Intimately wedded to the worlds of conceptual art and poetics, Radical Coherency collects Antin’s influential critical essays and spontaneous, performed lectures (or “talk pieces”) for the very first time, capturing one of the most distinctive perspectives in contemporary literature. The essays presented here range from the first serious assessment of Andy Warhol published in a major art journal, as well as Antin’s provocative take on Clement Greenberg’s theory of Modernism, to frontline interventions in present debates on poetics and fugitive pieces from the ’60s and ’70s that still sparkle today—and represent a gold mine for art historians of the period. From John Cage to Allan Kaprow, Mark Rothko to Ludwig Wittgenstein, Antin takes the reader on an idiosyncratic, personal journey through twentieth-century culture with his trademark antiformalist panache—one thatwill be welcomed by any fan of this consummate trailblazer.

Available in PDF, EPUB and Kindle. Book excerpt: For the centennial of Swann's Way: the most complete volume of Proust's poetry ever assembled, in a gorgeous deluxe edition As a young man, Proust wrote both poetry and prose. Even after he embarked on his masterful In Search of Lost Time at the age of thirty-eight, he never stopped writing poetry. His verse is often playful, filled with affection and satire, and is peppered with witty barbs at friends and people in his social circle of aristocrats, writers, musicians, and courtesans. Few of the poems collected here under the editorship of Harold Augenbraum, founder of the Proust Society of America, have ever been published in book form or translated into English until now. In this dual-language edition of new translations, Augenbraum has brought together nineteen renowned poets and poetry translators to bring Proust's exuberant verse back to life. For more than sixty-five years, Penguin has been the leading publisher of classic literature in the English-speaking world. With more than 1,500 titles, Penguin Classics represents a global bookshelf of the best works throughout history and across genres and disciplines. Readers trust the series to provide authoritative texts enhanced by introductions and notes by distinguished scholars and contemporary authors, as well as up-to-date translations by award-winning translators.

This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, many researchers have dedicated their efforts to constructing revolutionary machines and to providing them with forms of artificial intelligence to perform some of the most hazardous, risky or monotonous tasks historically assigned to human beings. Among those machines, mobile robots are undoubtedly at the cutting edge of current research directions. A rough classification of mobile robots can be considered: on the one hand, mobile robots oriented to human-made indoor environments; on the other hand, mobile robots oriented to unstructured outdoor environments, which could include flying oriented robots, space-oriented robots and underwater robots. The most common motion mechanism for surface mobile robots is the wheel-based mechanism, adapted both to flat surfaces, found in human-made environments, and to rough terrain, found in outdoor environments. However, some researchers have reported successful developments with leg-based mobile robots capable of climbing up stairs, although they require further investigation. The research work presented here focuses on wheel-based mobile robots that navigate in human-made indoor environments. The main problems described throughout this book are: Representation and integration of uncertain geometric information by means of the Symmetries and Perturbations Model (SPmodel). This model combines the use of probability theory to represent the imprecision in the location of a geometric element, and the theory of symmetries to represent the partiality due to characteristics of each type of geometric element. A solution to the first location problem, that is, the computation of an estimation for the mobile robot location when the vehicle is completely lost in the environment. The problem is formulated as a search in an interpretation tree using efficient matching algorithms and geometric constraints to reduce the size of the solution space. The book proposes a new probabilistic framework adapted to the problem of simultaneous localization and map building for mobile robots: the Symmetries and Perturbations Map (SPmap). This framework has been experimentally validated by a complete experiment which profited from ground-truth to accurately validate the precision and the appropriateness of the approach. The book emphasizes the generality of the solutions proposed to the different problems and their independence with respect to the exteroceptive sensors mounted on the mobile robot. Theoretical results are complemented by real experiments, where the use of multisensor-based approaches is highlighted.

Download or read book An Implementation of a Novel Localization Framework for Robots and Its Application to Multi robot Tasks written by Paul Mihai Maxim and published by ProQuest. This book was released on 2008 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the trend in robotics is to replace single robot platforms with teams of robots that cooperate to achieve a common goal. The main reasons are the fact that single robots may break down leading to a complete failure of achieving a goal and that certain tasks, such as chemical plume tracing, distributed sensing grids, or map generation, are difficult, if not impossible, to be solved with only one robot. Replacing a single robot by a team of robots can lead to a system that is fully distributed, more robust, noise tolerant, and highly scalable. One of the bottlenecks in the development of successful collaborative robotics is an enabling localization technology that shares the design criteria of collaborative robots, as we mentioned above. Existing localization technologies rely either on global information provided by GPS, beacons, and landmarks or on complex local information provided by vision systems. Using global information limits the use of the localization to specific environments and it is more prone to errors. Vision-based localization systems require expensive hardware and their accuracy is limited both by distance and lighting conditions. To address the problems with previous technologies we propose a novel plug-in 2D localization hardware module for multi-robot localization, based on trilateration, which is fully distributed, inexpensive and scalable. In 2D trilateration, to locate a remote robot, the sensing robot must know the locations of three "base points" in its own coordinate system and be able to measure distances from these three points to the remote robot. Our distance measurement method exploits the fact that sound travels significantly slower than light, allowing us to employ a Difference in Time of Arrival technique. Let us assume that we have two robots that are both equipped with our localization module. Each localization module has one radio frequency (RF) transceiver and three ultrasonic acoustic transceivers, which are also the "base points". Suppose robot 2 (remote robot) simultaneously emits an RF pulse and an acoustic pulse. When robot 1 (sensing robot) receives the RF pulse (almost instantaneously), a clock on robot 1 starts. When the acoustic pulse is received by each of the three acoustic transceivers on robot 1, the elapsed times are computed and converted to distances. Robot 1 is now able to use trilateration to compute the location of robot 2. Similarly, robot 2 can localize robot 1 when robot 1 emits the RF and acoustic pulse. To test our localization hardware we have developed a robot platform which we called Maxelbot . The modular design of this platform allows for easy addition of hardware modules, as we present later in this thesis. Next, we demonstrate the performance of this technology with various empirical tests on moving and non-moving platforms, both in controlled indoor environments and outdoors. We further test our localization module by using it to monitor the performance of a novel algorithm for uniform coverage of a region. Surveillance and mine detection are some applications that would benefit from this algorithm. Prior work has claimed that this task is impossible to solve for non-convex regions (Gage 1993). Our algorithm enables robots to uniformly cover regions of all shapes, such that the robot movements are not predictable and the region periphery is not neglected. The algorithm assumes that robots are independent and is physics-based, relying on an analogy with mean free paths of particles. Validation of the algorithm is rigorously provided via simulation and Maxelbot experiments. Finally, we demonstrate how our localization technology allows us to tackle an important problem in cooperative robotics - the self-organizing of chain formations in unknown environments. This algorithm assumes that robots are dependent and is also physics-based, using a surprisingly simple and elegant modification to the standard Artificial Physics framework (Spears and Gordon 1999). Validation of this algorithm is also rigorously provided via simulation, with the addition of demonstrations on the Maxelbots . The main contributions of this research are (a) the design and development of a novel platform-independent trilateration approach to multi-robot localization, (b) the design and development of our Maxelbot robot platform to test our localization module, (c) an algorithm that allows robots to uniformly cover arbitrarily shaped regions, and (d) an algorithm that enables a team of robots to self-organize in chain formations and explore unknown environments.
