Download or read book Harnessing Light written by National Research Council and published by National Academies Press. This book was released on 1998-09-25 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical science and engineering affect almost every aspect of our lives. Millions of miles of optical fiber carry voice and data signals around the world. Lasers are used in surgery of the retina, kidneys, and heart. New high-efficiency light sources promise dramatic reductions in electricity consumption. Night-vision equipment and satellite surveillance are changing how wars are fought. Industry uses optical methods in everything from the production of computer chips to the construction of tunnels. Harnessing Light surveys this multitude of applications, as well as the status of the optics industry and of research and education in optics, and identifies actions that could enhance the field's contributions to society and facilitate its continued technical development.

Download or read book LED Airfield Lighting System Operation and Maintenance written by John E. Burns and published by . This book was released on 2015 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides guidance for operating and maintaining light-emitting diode (LED) airfield ground lighting systems, including taxi guidance signs, elevated light fixtures, and in-pavement light fixtures. The research team prepared its guidance based on a literature review, an extensive survey of nearly 50 airports, and case studies of 12 airports. The guidebook begins with an overview of regulatory requirements as they relate to LED airfield lighting and a summary of the survey and case studies. The report then provides guidance on maintenance, including acceptance testing and warranty, fixture obsolescence and spare part recommendations, preventive maintenance and refurbishment/repair, maintenance practices during pavement repair, and environmental factors (e.g., vibration and moisture). The guidebook also covers operational considerations, including circuit configuration, heaters, monitoring, photometric and chromaticity analysis, and return-on-investment. The guidebook is supplemented by sample system requirements and maintenance schedules. The guidebook will be of particular interest to airport operations and maintenance (O & M) practitioners seeking to maximize the potential O & M benefits that LED lighting offers as they integrate and/or replace older airfield lighting with this new technology.

Download or read book Polymer Optical Fibres written by Christian-Alexander Bunge and published by Woodhead Publishing. This book was released on 2016-08-25 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer Optical Fibres: Fibre Types, Materials, Fabrication, Characterization, and Applications explores polymer optical fibers, specifically their materials, fabrication, characterization, measurement techniques, and applications. Optical effects, including light propagation, degrading effects of attenuation, scattering, and dispersion, are explained. Other important parameters like mechanical strength, operating temperatures, and processability are also described. Polymer optical fibers (POF) have a number of advantages over glass fibers, such as low cost, flexibility, low weight, electromagnetic immunity, good bandwidth, simple installation, and mechanical stability. Provides systematic and comprehensive coverage of materials, fabrication, properties, measurement techniques, and applications of POF Focuses on industry needs in communication, illumination and sensors, the automotive industry, and medical and biotechnology Features input from leading experts in POF technology, with experience spanning optoelectronics, polymer, and textiles Explains optical effects, including light propagation, degrading effects of attenuation, scattering, and dispersion

Download or read book Open Skies written by Kenneth I. Kellermann and published by Springer Nature. This book was released on 2020-01-01 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book on the history of the National Radio Astronomy Observatory covers the scientific discoveries and technical innovations of late 20th century radio astronomy with particular attention to the people and institutions involved. The authors have made extensive use of the NRAO Archives, which contain an unparalleled collection of documents pertaining to the history of radio astronomy, including the institutional records of NRAO as well as the personal papers of many of the pioneers of U.S. radio astronomy. Technical details and extensive citations to original sources are given in notes for the more technical readers, but are not required for an understanding of the body of the book. This book is intended for an audience ranging from interested lay readers to professional researchers studying the scientific, technical, political, and cultural development of a new science, and how it changed the course of 20th century astronomy.

Download or read book Aircraft Engineering Principles written by Lloyd Dingle and published by Routledge. This book was released on 2013-09-23 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft Engineering Principles is the essential text for anyone studying for licensed A&P or Aircraft Maintenance Engineer status. The book is written to meet the requirements of JAR-66/ECAR-66, the Joint Aviation Requirement (to be replaced by European Civil Aviation Regulation) for all aircraft engineers within Europe, which is also being continuously harmonised with Federal Aviation Administration requirements in the USA. The book covers modules 1, 2, 3, 4 and 8 of JAR-66/ECAR-66 in full and to a depth appropriate for Aircraft Maintenance Certifying Technicians, and will also be a valuable reference for those taking ab initio programmes in JAR-147/ECAR-147 and FAR-147. In addition, the necessary mathematics, aerodynamics and electrical principles have been included to meet the requirements of introductory Aerospace Engineering courses. Numerous written and multiple choice questions are provided at the end of each chapter, to aid learning.
