Download or read book Catenary Optics written by Xiangang Luo and published by Springer. This book was released on 2019-01-09 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the first comprehensive introduction to the optical properties of the catenary function, and includes more than 200 figures. Related topics addressed here include the photonic spin Hall effect in inhomogeneous anisotropic materials, coupling of evanescent waves in complex structures, etc. After familiarizing readers with these new physical phenomena, the book highlights their applications in plasmonic nanolithography, flat optical elements, perfect electromagnetic absorbers and polarization converters. The book will appeal to a wide range of readers: while researchers will find new inspirations for historical studies combining mechanics, mathematics, and optics, students will gain a wealth of multidisciplinary knowledge required in many related areas. In fact, the catenary function was deemed to be a “true mathematical and mechanical form” in architecture by Robert Hooke in the 1670s. The discovery of the mathematical form of catenaries is attributed to Gottfried Leibniz, Christiaan Huygens and Johann Bernoulli in 1691. As the founders of wave optics, however, Hooke and Huygens did not recognize the importance of catenaries in optics. It is only in recent decades that the link between catenaries and optics has been established.

Book excerpt: This book focuses on the deep learning technologies and their applications in the catenary detection of high-speed railways. As the only source of power for high-speed trains, the catenary's service performance directly affects the safe operation of high-speed railways. This book systematically shows the latest research results of catenary detection in high-speed railways, especially the detection of catenary support component defect and fault. Some methods or algorithms have been adopted in practical engineering. These methods or algorithms provide important references and help the researcher, scholar, and engineer on pantograph and catenary technology in high-speed railways. Unlike traditional detection methods of catenary support component based on image processing, some advanced methods in the deep learning field, including convolutional neural network, reinforcement learning, generative adversarial network, etc., are adopted and improved in this book. The main contents include the overview of catenary detection of electrified railways, the introduction of some advance of deep learning theories, catenary support components and their characteristics in high-speed railways, the image reprocessing of catenary support components, the positioning of catenary support components, the detection of defect and fault, the detection based on 3D point cloud, etc.
Download or read book The Electrical Contact of the Pantograph Catenary System written by Guangning Wu and published by Springer. This book was released on 2019-04-12 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the basic scientific theory and related application technologies of the pantograph–catenary system, including research findings on pantograph/catenary contact resistance, pantograph interface thermal effect, laws and characteristics of current-carrying friction and wear, the main research methods for pantograph arcs, the effects of arcs on pantograph systems and onboard equipment, and the materials used for pantographs and contact wires. Given its scope, it offers a valuable resource for students, scholars, and development engineers alike. The relationship between pantograph and catenary is one of the three core aspects of the safe operation of high-speed electrified railways. The pantograph system provides electric power for the high-speed train through the sliding electric contact. As the train’s operating speed increases, the pantograph system enters a state of prolonged sliding/vibration, resulting in frequent arcs, electrode erosion, and increased wear.

Download or read book Power Supply Energy Management and Catenary Problems written by Eduardo Pilo and published by WIT Press. This book was released on 2010 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: In latter years, energy efficiency has become a crucial concern for every transportation mode, but it is in electrified railways where energy savings have shown a bigger potential due to (i) regenerative braking, that allows converting kinetic energy into electric power, and (ii) vehicle interconnection, that allows other trains to use regenerated power. Power supply and energy management will continue to develop in the future. This book gathers under a single cover several papers published in the Computer on Railways series (IX, X and XI) and focuses on power supply and energy management. Some of the discussed themes are: modelling, simulation and optimisation of AC and DC infrastructure, analysis of rolling stock consumption, and innovative approaches in power supply operation. This book will be invaluable to management consultants, engineers, planners, designers, manufacturers, operators and IT specialists who need to keep abreast of the latest developments in the field.
Download or read book Algebraic Geometry written by Ulrich Görtz and published by Springer Science & Business Media. This book was released on 2010-08-09 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the reader to modern algebraic geometry. It presents Grothendieck's technically demanding language of schemes that is the basis of the most important developments in the last fifty years within this area. A systematic treatment and motivation of the theory is emphasized, using concrete examples to illustrate its usefulness. Several examples from the realm of Hilbert modular surfaces and of determinantal varieties are used methodically to discuss the covered techniques. Thus the reader experiences that the further development of the theory yields an ever better understanding of these fascinating objects. The text is complemented by many exercises that serve to check the comprehension of the text, treat further examples, or give an outlook on further results. The volume at hand is an introduction to schemes. To get startet, it requires only basic knowledge in abstract algebra and topology. Essential facts from commutative algebra are assembled in an appendix. It will be complemented by a second volume on the cohomology of schemes.

Download or read book Jasper Johns written by Jasper Johns and published by . This book was released on 2005 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: After completing the installation of his 1996 retrospective at New York's Museum of Modern Art, Jasper Johns retreated to his studio in Connecticut to wipe the slate clean, beginning a body of work that was a dramatic departure from anything he had made before. This volume reproduces for the first time the complete series of those magnificent works that Johns, one of our greatest living artists, has made over the last eight years.The first painting in this new series included a string hanging from upper right to lower left, generating a curve called a "catenary," and this curve became the compositional backbone of the entire series. Johns produced a total of 61 paintings, drawings and prints based on the catenary theme, all of which are reproduced in this volume. The work is saturated with autobiographical references, both transparent and opaque, while it simultaneously encourages multiple layers of meaning. Sensual surfaces, fragile constructions, and formal rigor meet allusions to key moments in the history of modern art and motifs from Johns's earlier work. The poetry of Johns's catenary series is explored in an illustrated essay by the scholar Scott Rothkopf, published alongside the catalogue's 51 color plates.
