Description : Seminar paper from the year 2008 in the subject Engineering - Industrial Engineering and Management, grade: 1,3, Vrije University Brussel (Solvay Business School), course: Advanced Technology, language: English, abstract: The magnetic levitation train analysed in this study was developed in Germany by the Transrapid International GmbH & Co. KG, a joint venture by Siemens AG and ThyssenKrupp AG, as a means for high speed transportation. First prototypes were presented to the public as early as 1969 and 1979, yet, the first public high-speed maglev track was opened only four years ago in Shanghai, China. Despite the fact that businesspeople like engineers from all sorts of backgrounds speak very highly of the technology, the Shanghai track remains the only commercially operated one thus far.1 Purpose of this paper is to analyse the potential of the maglev train, to assess its strengths and weaknesses, and to spot opportunities as well as threats to the application of this state-of-the-art - or perhaps ahead-of-its-time - technology.
Description : From Peter Pan to Harry Potter, from David Copperfield to levitating toys, there is magic in conquering gravity. In this first-ever popular introduction to âeoemaglevâe âe" the use of magnetic forces to overcome gravity and frictionâe"James D. Livingston takes lay readers on a journey of discovery, from basic concepts to todayâe(tm)s most thrilling applications. The tour begins with examples of our historical fascination with levitation, both real and fake. At the next stop, Livingston introduces readers to the components of maglev: gravitational and magnetic forces in the universe, force fields, diamagnetism and stabilization, superdiamagnetism and supercurrents, maglev nanotechnology, and more. He explores the development of the superconductors that are making large-scale levitation devices possible, and the use of magnetic bearings in products ranging from implanted blood pumps to wind turbines, integrated circuit fabrication, and centrifuges to enrich uranium. In the last chapters, we arrive at the science behind maglev transportation systems, such as Chinese trains that travel 250 miles per hour without touching the tracks. Packed with fascinating anecdotes about the colorful personalities who have âeoefought friction by fighting gravity,âe the book maintains accuracy throughout while it entertains and informs technical and nontechnical readers alike. With so many new applications for magnetic levitation on the horizon, Rising Force is sure to retain its own magic for years to come.
Description : Hydrogen stands out as the best alternative to traditional polluting fossil fuels for many reasons-it can be produced without pollution, is nontoxic and noncorrosive, and we can never run out of it. It is as safe as or safer than the fuels we currently use and can be made virtually anywhere.
Description : Japan is embarked on a demographic transition without precedent in human history: the population is both declining and ageing rapidly. This raises important questions about the country's future economic geography, as public policies will need both to respond to these shifts and also to shape them.
Description : In October 2003, a group of experts met in Beijing under the auspices of the Chinese Academy of Sciences, Chinese Academy of Engineering, and National Academy of Engineering (NAE)/National Research Council (NRC) of the National Academies to continue a dialogue and eventually chart a rational course of energy use in China. This collection of papers is intended to introduce the reader to the complicated problems of urban air pollution and energy choices in China.
Description : This volume aims to review some of the recent developments and trends that seem especially relevant to any attempt to understand near-term-future possibilities; to consider what a variety of knowledgeable people are saying about changes and developments that could occur; and to relate the possibilities to needs and opportunities for human factors research. Human factors, in this case, includes not only the implications of human capabilities and limitations for the design of equipment and machines intended for human use, but also applied psychology in a more general sense. In particular, it is taken to involve social systems as well as physical ones, the interaction of people with the environment as well as with machines, the facilitation of communication between people as well as between people and computers, and the design of policies and procedures as well as the design of equipment. The author's intention is to focus on anticipated problems -- including opportunities as well as difficulties -- and ask how human factors research might contribute to solutions. It is assumed that there are ways in which such research could be useful in addressing societal problems that the profession has not yet realized and that these are more likely to be recognized in the future if the community is actively seeking to identify them.
Description : The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)
