Download or read book Arc of the Medicine Line written by Tony Rees and published by U of Nebraska Press. This book was released on 2007-01-01 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today the borderland between Canada and the United States is a wide, empty sweep of wheat fields and pasture, measured by a grid of gravel roads that sees little traffic and few people who do not make their lives there. It has been much this way for more than a century now, but there was a moment when the great silence shrouding this place was broken, and that moment changed it forever. Arc of the Medicine Line is a compelling narrative of that moment?the completion of the official border between the United States and Canada in 1874. ø In late July of 1874, the Sweetgrass Hills sheltered the greatest accumulation of scientists, teamsters, scouts, cooks, and soldiers to be seen in this part of the world before the coming of the railways. The men of the boundary commissions?American, British, and Canadian?established an astronomical station and the last of their supply depots as they prepared to draw the Medicine Line across the final hundred of the nearly nine hundred miles between Manitoba?s Lake of the Woods and the Continental Divide. In the brief weeks the surveyors and soldiers spent in Milk River country, they witnessed, and played a singular part in, the beginning of the end for the open West. That hot, dry summer of 1874 marked the outside world?s final assault on this last frontier.
Download or read book Arc Routing written by Moshe Dror and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arc Routing: Theory, Solutions and Applications is about arc traversal and the wide variety of arc routing problems, which has had its foundations in the modern graph theory work of Leonhard Euler. Arc routing methods and computation has become a fundamental optimization concept in operations research and has numerous applications in transportation, telecommunications, manufacturing, the Internet, and many other areas of modern life. The book draws from a variety of sources including the traveling salesman problem (TSP) and graph theory, which are used and studied by operations research, engineers, computer scientists, and mathematicians. In the last ten years or so, there has been extensive coverage of arc routing problems in the research literature, especially from a graph theory perspective; however, the field has not had the benefit of a uniform, systematic treatment. With this book, there is now a single volume that focuses on state-of-the-art exposition of arc routing problems, that explores its graph theoretical foundations, and that presents a number of solution methodologies in a variety of application settings. Moshe Dror has succeeded in working with an elite group of ARC routing scholars to develop the highest quality treatment of the current state-of-the-art in arc routing.

Download or read book Optimizing Crossings in Circular Arc Drawings and Circular Layouts written by Myroslav Kryven and published by BoD – Books on Demand. This book was released on 2022-02-03 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: A graph is an abstract network that represents a set of objects, called vertices, and relations between these objects, called edges. Graphs can model various networks. For example, a social network where the vertices correspond to users of the network and the edges represent relations between the users. To better see the structure of a graph it is helpful to visualize it. A standard visualization is a node-link diagram in the Euclidean plane. In such a representation the vertices are drawn as points in the plane and edges are drawn as Jordan curves between every two vertices connected by an edge. Edge crossings decrease the readability of a drawing, therefore, Crossing Optimization is a fundamental problem in Computer Science. This book explores the research frontiers and introduces novel approaches in Crossing Optimization.
Download or read book Switching Arc Phenomena in Transmission Voltage Level Vacuum Circuit Breakers written by Zhiyuan Liu and published by Springer Nature. This book was released on 2021-05-20 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vacuum circuit breakers are widely used in distribution power systems for their advantages such as maintenance free and eco-friendly. Nowadays, most circuit breakers used at transmission voltage level are SF6 circuit breakers, but the SF6 they emit is one of the six greenhouse gases defined in Kyoto Protocol. Therefore, the development of transmission voltage level vacuum circuit breaker can help the environment. The switching arc phenomena in transmission voltage level vacuum circuit breakers are key issues to explore. This book focuses on the high-current vacuum arcs phenomena at transmission voltage level, especially on the anode spot phenomena, which significantly influence the success or failure of the short circuit current interruption. Then, it addresses the dielectric recovery property in current interruption. Next it explains how to determine the closing/opening displacement curve of transmission voltage level vacuum circuit breakers based on the vacuum arc phenomena. After that, it explains how to determine key design parameters for vacuum interrupters and vacuum circuit breakers at transmission voltage level. At the end, the most challenging issue for vacuum circuit breakers, capacitive switching in vacuum, is addressed. The contents of this book will benefit researchers and engineers in the field of power engineering, especially in the field of power circuit breakers and power switching technology.

Download or read book Arc Continent Collision written by Dennis Brown and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arc-continent collision has been one of the important tectonic processes in the formation of mountain belts throughout geological time, and it continues to be so today along tectonically active plate boundaries such as those in the SW Pacific or the Caribbean. Arc-continent collision is thought to have been one of the most important process involved in the growth of the continental crust over geological time, and may also play an important role in its recycling back into the mantle via subduction. Understanding the geological processes that take place during arc-continent collision is therefore of importance for our understanding of how collisional orogens evolve and how the continental crust grows or is destroyed. Furthermore, zones of arc-continent collision are producers of much of the worlds primary economic wealth in the form of minerals, so understanding the processes that take place during these tectonic events is of importance in modeling how this mineral wealth is formed and preserved. This book brings together seventeen papers that are dedicated to the investigation of the tectonic processes that take place during arc-continent collision. It is divided into four sections that deal firstly with the main players involved in any arc-continent collision; the continental margin, the subduction zone, and finally the volcanic arc and its mineral deposits. The second section presents eight examples of arc-continent collisions that range from being currently active through to Palaeoproterozoic in age. The third section contains two papers, one that deals with the obduction of large-slab ophiolites and a second that presents a wide range of physical models of arc-continent collision. The fourth section brings everything that comes before together into a discussion of the processes of arc-continent collision.
