This books contains the Proceedings of the 4th International Conference on Power Transmissions, that was held in Sinaia, Romania from June 20 -23, 2012. Power Transmissions is a very complex and multi-disciplinary scientific field of Mechanical Engineering that covers the different types of transmissions (mechanical, hydraulic, pneumatic) as well as all the machine elements involved, such as gears, bearings, shafts, couplings and a lot more. It concerns not only their basic theory but also their design, analysis, testing, application and maintenance. The requirements set to modern power transmissions are really tough to meet: They need to be more efficient, stronger, smaller, noiseless, easier to produce and to cost less. There is a strong demand to become easier in operation and maintenance, or even automatic and in maintenance-free. Last but not least, they should be easily recycled and respect the environment. Joint efforts of specialists from both academia and industry can significantly contribute to fulfill these needs. The main goal of this conference was to bring together experts from all over the world and present the latest developments in the field of Power Transmissions.
Updated throughout for the third edition, Theory of Gearing: Kinematics, Geometry, and Synthesis is an essential resource for engineers in the field of gearing. Detailing gear design, production, inspection, and application, the book covers cutting-edge gear types to enable the reader to fully keep track of modern gear developments. Demonstrating the rigorous scientific theory behind optimal gear design, manufacture, and performance, a key focus of the new edition is on aiding engineers in designing low noise transmissions in smaller sizes, improving fuel consumption and reducing emissions. Chapters included will discuss key features of Split-Power-Transmission-Systems (SPTS) with equal (almost equal) power share, and Uniform Rotary Motion. Entirely new chapters for the third edition include: Parallel-Axes involute gearing of specific design and gear, and Novikov/Conformal and High-Conformal gearing. The book will be of interest to engineers and researchers in the gearing industry. It will also have relevance to those working in tribology, metallurgy, and materials processing, alongside engineers working in precision manufacturing.
This book charts the past, present, and future of studies on medieval technology, art, and craft practices. Inspired by Villard’s enigmatic portfolio of artistic and engineering drawings, this collection explores the multiple facets of medieval building represented in this manuscript (Paris, Bibliothèque nationale de France, MS Fr 19093). The book’s eighteen essays and two introductions showcase traditional and emergent methods for the study of medieval craft, demonstrating how these diverse approaches collectively amplify our understanding about how medieval people built, engineered, and represented their world. Contributions range from the analysis of words and images in Villard’s portfolio, to the close analysis of masonry, technological marvels, and gothic architecture, pointing the way toward new avenues for future scholarship to explore. Contributors are: Mickey Abel, Carl F. Barnes Jr., Robert Bork, George Brooks, Michael T. Davis, Amy Gillette, Erik Gustafson, Maile S. Hutterer, John James, William Sayers, Ellen Shortell, Alice Isabella Sullivan, Richard Alfred Sundt, Sarah Thompson, Steven A. Walton, Maggie M. Williams, Kathleen Wilson Ruffo, and Nancy Wu.
The first Workshop on Mechanisms, Transmissions and Applications -- MeTrApp-2011 was organized by the Mechatronics Department at the Mechanical Engineering Faculty, “Politehnica” University of Timisoara, Romania, under the patronage of the IFToMM Technical Committees Linkages and Mechanical Controls and Micromachines. The workshop brought together researchers and students who work in disciplines associated with mechanisms science and offered a great opportunity for scientists from all over the world to present their achievements, exchange innovative ideas and create solid international links, setting the trend for future developments in this important and creative field. The topics treated in this volume are mechanisms and machine design, mechanical transmissions, mechatronic and biomechanic applications, computational and experimental methods, history of mechanism and machine science and teaching methods.
"This report assesses demand for a mechanism that brings together forest certification and fair trade in the timber market. Timber buyers from 21 countries were surveyed as part of this study - with more detailed value chain analysis in 4 country case studies. The report concludes that there is indeed both demand and practical options to do more for community forest producers. A historic opportunity exists to bring together forest certification and fair trade in the interests both of communities and the forests on which they depend."--Résumé de l'éditeur.
Ambient Assisted Living and Enhanced Living Environments: Principles, Technologies and Control separates the theoretical concepts concerning the design of such systems from their real-world implementations. For each important topic, the book bridges theory and practice, introducing the instruments needed by professionals in their activities. To this aim, topics are presented in a logical sequence, with the introduction of each topic motivated by the need to respond to claims and requirements from a wide range of AAL/ELE applications. The advantages and limitations of each model or technology are presented through concrete case studies for AAL/ELE systems. The book also presents up-to-date te...
