Mechatronic Systems

Mechatronics, the synergistic blend of mechanics, electronics, and computer science, has evolved over the past twenty five years, leading to a novel stage of engineering design. By integrating the best design practices with the most advanced technologies, mechatronics aims at realizing high-quality products, guaranteeing at the same time a substantial reduction of time and costs of manufacturing. Mechatronic systems are manifold and range from machine components, motion generators, and power producing machines to more complex devices, such as robotic systems and transportation vehicles. With its twenty chapters, which collect contributions from many researchers worldwide, this book provides an excellent survey of recent work in the field of mechatronics with applications in various fields, like robotics, medical and assistive technology, human-machine interaction, unmanned vehicles, manufacturing, and education. We would like to thank all the authors who have invested a great deal of time to write such interesting chapters, which we are sure will be valuable to the readers. Chapters 1 to 6 deal with applications of mechatronics for the development of robotic systems. Medical and assistive technologies and human-machine interaction systems are the topic of chapters 7 to 13.Chapters 14 and 15 concern mechatronic systems for autonomous vehicles. Chapters 16-19 deal with mechatronics in manufacturing contexts. Chapter 20 concludes the book, describing a method for the installation of mechatronics education in schools

Preservation and development in Japanese architecture and town planning

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Architecture and Planning, 1994.Includes bibliographical references (v 2., leaves 309-325).The study examines the architectural preservation program as it has developed over the past century in Japan, and demonstrates how relics of the past have been manipulated and re-interpreted by individuals and communities seeking to define a modern identity. The study chronicles the development of preservation practice from a national perspective, followed by a local historical analysis of the town of Tsumago in Nagano Prefecture. It is proposed that a nativist and modernist construction of the common Japanese house has had a special place in the history of the modern movement in Japan which influenced the conceptualization, study and preservation of traditional architecture over the past century. Also, the legal tools and field practices of both the national preservation program and the grass-roots district preservation movement have been tied to ideological and political concerns which have affected building designation, restoration, and public presentation. The most important example of the grass-roots district preservation movement in Japan is Tsumago-juku in Nagano Prefecture, the first example of such a movement in Asia. It is demonstrated that Tsumago's place in the formation of Japan's modern national identity was of primary importance to the success of its preservation effort. Restoration work there resulted in important national legislation and created a conflict between the "living tradition" of local carpentry and community vs. professional preservationist. This centered on the nature of architectural tradition and definition of authenticity. As a result of the preservation effort, the town's history and traditions have been re-invented to suit the needs of the present, and its material historicity has been compromised in the name of a greater authenticity in the building process. Yet the modernist ideal of a structurally "honest" and materially "natural" Japanese house has made the acceptance of preservation intervention problematic in the architectural community, further demonstrating that the way old houses are preserved is as much a reflection of the architectural and political ideology of our time as they are a portrait of the past.by Cherie Wendelken-Mortensen.Ph.D
