Book excerpt: Skyscrapers may be our most powerful tool in providing dense, energy-efficient living for a rapidly urbanizing population, but this typology faces certain limitations inherent to its traditional form, namely, the lack of interplay between tower, urban context, and community. Through a historical overview, case study analysis, and a series of design considerations, this report explores how ropeless and multidirectional elevator technologies can enable cities to be more interconnected, efficient, and accessible.Running on a series of seamless loops, and powered by magnetic levitation, ropeless and multidirectional elevator cabins could follow a multiplicity of routes within a given building, not only reducing the quantity of shafts needed and increasing rentable area, but also allowing elevators more options in terms of where they stop across a building's dimensions. When paired with skybridges and "skyspaces," at-height services and communities could be easily linked with one another, bolstering the critical link between a piece of architecture and the urban sphere, while combating some of the insularity endemic to skyscrapers.This Research Report is the product of two years of research by the CTBUH Research Office in Venice, CTBUH Staff, professionals in the field, and a research team of architecture and supporting academic advisors. It is part of a series of research reports that offer insight into specific areas of skyscraper research, offering a wealth of knowledge essential for industry professionals, academic researchers and all others interested in the relationship between skyscrapers and urban habitat.

Download or read book Building the Skyline written by Jason M. Barr and published by Oxford University Press. This book was released on 2016-05-12 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Manhattan skyline is one of the great wonders of the modern world. But how and why did it form? Much has been written about the city's architecture and its general history, but little work has explored the economic forces that created the skyline. In Building the Skyline, Jason Barr chronicles the economic history of the Manhattan skyline. In the process, he debunks some widely held misconceptions about the city's history. Starting with Manhattan's natural and geological history, Barr moves on to how these formations influenced early land use and the development of neighborhoods, including the dense tenement neighborhoods of Five Points and the Lower East Side, and how these early decisions eventually impacted the location of skyscrapers built during the Skyscraper Revolution at the end of the 19th century. Barr then explores the economic history of skyscrapers and the skyline, investigating the reasons for their heights, frequencies, locations, and shapes. He discusses why skyscrapers emerged downtown and why they appeared three miles to the north in midtown-but not in between the two areas. Contrary to popular belief, this was not due to the depths of Manhattan's bedrock, nor the presence of Grand Central Station. Rather, midtown's emergence was a response to the economic and demographic forces that were taking place north of 14th Street after the Civil War. Building the Skyline also presents the first rigorous investigation of the causes of the building boom during the Roaring Twenties. Contrary to conventional wisdom, the boom was largely a rational response to the economic growth of the nation and city. The last chapter investigates the value of Manhattan Island and the relationship between skyscrapers and land prices. Finally, an Epilogue offers policy recommendations for a resilient and robust future skyline.
Download or read book Switched Reluctance Motor Drives written by R. Krishnan and published by CRC Press. This book was released on 2017-12-19 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: The switched reluctance machine (SRM) is the least expensive electrical machine to produce, yet one of the most reliable. As such, research has blossomed during the last decade, and the SRM and variable drive systems using SRMs are receiving considerable attention from industry. Because they require a power electronic converter and controller to function, however, successful realization of an SRM variable drive system demands an understanding of the converter and controller subsystems and their integration with the machine. Switched Reluctance Motor Drives provides that understanding. It presents a unified view of the machine and its drive system from all of its system and subsystem aspects. With a careful balance of theory and implementation, the author develops the analysis and design of SRMs from first principles, introduces a wide variety of power converters available for driving the SRM, and systematically presents both low- and high-performance controllers. The book includes an in-depth study of acoustic noise and its minimization along with application examples that include comparisons between ac and dc drives and SRM drive. The result is the first book that provides a state-of-the-art knowledge of SRMs, power converters, and their use with both sensor-based and sensorless controllers. Switched Reluctance Motor Drives enables both students and engineers to learn all aspects of SRM drive systems and appreciate the interdependence of the various subsystems in performance optimization.

Download or read book Magnetic Levitation written by Hyung-Suk Han and published by Springer. This book was released on 2016-01-02 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of magnetic levitation (Maglev) technologies, from fundamental principles through to the state-of-the-art, and describes applications both realised and under development. It includes a history of Maglev science and technology showing the various milestones in its advancement. The core concepts, operating principles and main challenges of Maglev applications attempted across various fields are introduced and discussed. The principle difficulties encountered when applying Maglev technology to different systems, namely air gap control and stabilization, are addressed in detail. The book describes how major advancements in linear motor and magnet technologies have enabled the development of the linear-motor-powered Maglev train, which has a high speed advantage over conventional wheeled trains and has the potential to reach speed levels achieved by aircraft. However, many expect that Maglev technology to be a green technology that is applied not only in rail transportation, but also in diverse other fields; to ensure clean transfer in LCD manufacturing, in ropeless high speed elevators, small capacity rail transportation, space vehicle launchers, missile testers, energy storage, and so on. These potential applications and their unique challenges and proposed technological solutions are introduced and discussed in depth. The book will provide readers from academia, research institutes and industry with insights on where and how to apply Maglev technology, and will serve as a guide to the realization of their Maglev applications.

This book was released on 2012-03-21 with total page 2079 pages. Available in PDF, EPUB and Kindle. Book excerpt: As future generation electrical, information engineering and mechatronics become specialized and fragmented, it is easy to lose sight of the fact that many topics in these areas have common threads and, because of this, advances in one discipline may be transmitted to others. The 2011 International Conference on Electrical, Information Engineering and Mechatronics (EIEM 2011) is the first conference that attempts to follow the above idea of hybridization in electrical, information engineering, mechatronics and applications. This Proceedings of the 2011 International Conference on Electrical, Information Engineering and Mechatronics provides a forum for engineers and scientists to address the most innovative research and development including technical challenges and social, legal, political, and economic issues, and to present and discuss their ideas, results, works in progress and experience on all aspects of electrical, information engineering, mechatronics and applications. Engineers and scientists in academia, industry, and government will find a insights into the solutions that combine ideas from multiple disciplines in order to achieve something more significant than the sum of the individual parts in all aspects of electrical, information engineering, mechatronics and applications.
