Download or read book Panoramic Optical Servoing A New Dimension in the Inspection and Repair of Refractories Using a Telerobot written by and published by Cuvillier Verlag. This book was released on 2004-12-19 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automated optical inspection system for service in an extremely hostile industrial environment was designed, integrated, implemented and tested. The specific application pertains to robotic inspection and subsequent repair of refractory linings in a variety of very hot steel making vessels. The principle of operation of the proposed concept of combining telerobotics and panoramic optical servoing (POS) for inspection and repair with a final decisionmaking intervention by a human operator is presented. The reader is introduced to the theoretical and practical background necessary to set up an image processing system for panoramic optical servoing under the extreme environmental conditions prevailing in a steel plant. The optomechanical process sequence for the proposed combination of telerobotics and panoramic optical servoing is described. It entails image acquisition, panoramic combination of image frames via normalized phase correlation and the mapping of the panorama to robotic actuator displacements. Experimental results using a standard 6R industrial robot have shown the full functionality of the system concept. The feasibility of panoramic stereo has been demonstrated. However, the reliability of the radial distance information obtained from stereoscopic calculations was considered to be insufficient for applications in such dangerous environments. Testing the developed image processing system at temperatures between 1100°C and 1600°C demonstrated not only applicability to the task of POS, but also the possibility to use such a measurement system in a variety of other high temperature applications in a steel plant.

Available in PDF, EPUB and Kindle. Book excerpt: Bound Lives chronicles the lived experience of race relations in northern coastal Peru during the colonial era. Rachel Sarah O'Toole examines how Andeans and Africans negotiated and employed casta, and in doing so, constructed these racial categories. Royal and viceregal authorities separated "Indians" from "blacks" by defining each to specific labor demands. Casta categories did the work of race, yet, not all casta categories did the same type of work since Andeans, Africans, and their descendants were bound by their locations within colonialism and slavery. The secular colonial legal system clearly favored indigenous populations. Andeans were afforded greater protections as "threatened" native vassals. Despite this, in the 1640s during the rise of sugar production, Andeans were driven from their assigned colonial towns and communal property by a land privatization program. Andeans did not disappear, however; they worked as artisans, muleteers, and laborers for hire. By the late seventeenth and early eighteenth centuries, Andeans employed their legal status as Indians to defend their prerogatives to political representation that included the policing of Africans. As rural slaves, Africans often found themselves outside the bounds of secular law and subject to the judgments of local slaveholding authorities. Africans therefore developed a rhetoric of valuation within the market and claimed new kinships to protect themselves in disputes with their captors and in slave-trading negotiations. Africans countered slaveholders' claims on their time, overt supervision of their labor, and control of their rest moments by invoking customary practices. Bound Lives offers an entirely new perspective on racial identities in colonial Peru. It highlights the tenuous interactions of colonial authorities, indigenous communities, and enslaved populations and shows how the interplay between colonial law and daily practice shaped the nature of colonialism and slavery.
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
Download or read book Swimming and Flying in Nature written by Theodore Wu and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Symposium on Swimming and Flying in Nature which was held at the California Institute of Technology, Pasadena, California from July 8-12, 1974 was conceived with the objective of providing an interdisciplinary forum for the discussion of funda mental biological and fluid mechanical aspects of these forms of natura110comotion. It was the earnest hope of all concerned in the organization of the Symposium that the exchange of knowledge and interaction of ideas from the disciplines involved would stimu late new research in this developing field. If the liveliness of the discussion generated among the 250 or so participants is any measure, then this objective was fulfilled to a significant degree. These two companion volumes contain the manuscripts of the papers presented during the Symposium. It is hoped that this permanent record will serve to perpetuate the enthusiasm and active thought generated during those days in Pasadena. The first volume contains the proceedings of the first two days of the confer ence (Sessions I to IV) which concentrated on the locomotion of micro-organisms. The second volume (Sessions V to VIII) deals with the propulsion of larger fish, insects and birds. Professor Sir James Lighthill's Special Invited Lecture which opened the Symposium is contained in the second volume, rather than the first, since it deals with natural flight.

Download or read book Interpersonal Coordination written by Nobuyuki Inui and published by Springer. This book was released on 2018-08-28 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the fascinating area of interpersonal coordination in force production tasks, outlining the author’s extensive research to date and presenting stimulating new perspectives. The purpose is to provide a detailed exposition of current understanding of the science behind interpersonal joint action. Readers will find clear explanation of concepts from social cognition and neuroscience that are key to an understanding of the field, including the social brain hypothesis, the mirror neuron system, and joint action, as well as other relevant background information. The author then proceeds to present an overview of recent original studies on interpersonal movement coordination performed at his laboratory in Japan. These studies provide insights into such issues as complementary and synchronous force production in joint action, bidirectional transfer between joint and solo actions, and motor control hierarchy in joint action involving bimanual force. They also set the direction for integration of knowledge of physical properties and social cognition. The book will be of interest for researchers and graduate students in all areas of the biomedical sciences.

Book excerpt: Enaction is a recent approach in psychology and in cognitive sciences and it remains not easy to understand and to situate. Its introduction in the field of Computer Technology and Multimodal Interfaces has been initiated explicitly in the FP6 Enactive Interfaces Network of Excellence. It is nothing less thon a conceptual revolution, an important paradigm shift.This leads ta necessary confrontations between several disciplines in order ta bridge gags, understand different ways of thinking, plunge within unfamiliar defnitions, rub up with different schools, and work to extend each domain by new concepts, methods and results. Enaction and Enacfive Interfaces: an handbook of Terms aims ut overcoming the interdisciplinary, gap inherent to this new paradigm. It has been designed as a Cool ta constitute a common vision on Enaction, Enactive Interaction, Enaction Knowledge and Enactive systems, allowing students and researchers ta reach, ut a glance, a suffcient interdisciplinary level, in order to tackle effiqiently the new question of « Enaction and Technology ». Through a wide panel of words, terms, expressions, presented in a synthetic form, shorter thon scientific papers or disciplinary books, it aims ut creating a global understanding of the Enactive paysage, and stimulating new researches ut the crosspoint of disciplines, and ultimately ut fostering a new generation of young researchers on Enaction and Enactive Systems.

Download or read book Air Lasing written by Pavel Polynkin and published by Springer. This book was released on 2017-12-16 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first comprehensive, interdisciplinary review of the rapidly developing field of air lasing. In most applications of lasers, such as cutting and engraving, the laser source is brought to the point of service where the laser beam is needed to perform its function. However, in some important applications such as remote atmospheric sensing, placing the laser at a convenient location is not an option. Current sensing schemes rely on the detection of weak backscattering of ground-based, forward-propagating optical probes, and possess limited sensitivity. The concept of air lasing (or atmospheric lasing) relies on the idea that the constituents of the air itself can be used as an active laser medium, creating a backward-propagating, impulsive, laser-like radiation emanating from a remote location in the atmosphere. This book provides important insights into the current state of development of air lasing and its applications.

Book excerpt: Visual servoing is a well-known approach to guide robots using visual information. Image processing, robotics, and control theory are combined in order to control the motion of a robot depending on the visual information extracted from the images captured by one or several cameras. With respect to vision issues, a number of issues are currently being addressed by ongoing research, such as the use of different types of image features (or different types of cameras such as RGBD cameras), image processing at high velocity, and convergence properties. As shown in this book, the use of new control schemes allows the system to behave more robustly, efficiently, or compliantly, with fewer delays. Related issues such as optimal and robust approaches, direct control, path tracking, or sensor fusion are also addressed. Additionally, we can currently find visual servoing systems being applied in a number of different domains. This book considers various aspects of visual servoing systems, such as the design of new strategies for their application to parallel robots, mobile manipulators, teleoperation, and the application of this type of control system in new areas.
