The purpose of this handbook is to bring together information on the special devices and associated systems which have been developed to assist the handicapped in living and vocational pursuits and in clinical use. This unique work places emphasis on the devices and systems plus includes sufficient background information to clarify the objectives and use. The general subject matter is divided into two major areas. The first area deals primarily with the environment of the handicapped. The second section deals with devices for personal assist systems-such as for testing, evaluation, and training-and devices which provide individualized support. The information in this comprehensive handbook will assist those working directly in the broad field of rehabilitation of the handicapped and also those associated with the subject matter in a peripheral way, including counseling and vocational evaluation.
Industrieroboter gehoren heute zum Alltag. In den letzten zehn Jahren verlagerte sich der Schwerpunkt der Neuentwicklungen weg von den Robotern selbst, hin zu alternativen Formen der kunstlichen Intelligenz, mit denen die Gerate ausgestattet werden. Dem Rechnung tragend, beschaftigt sich die zweite Auflage dieses Handbuchs vor allem mit Anwendungen und Strategien zur Problemlosung in der Industrie. Angesprochen werden Themen wie Graphiksimulatoren, objektorientierte Software, Kommunikationssysteme und Mikro- und Nanoroboter. (04/99)
The 14th International Conference on Wear of Materials took place in Washington, DC, USA, 30 March - 3 April 2003. These proceedings contain over two-hundred peer reviewed papers containing the best research, technical developments and engineering case studies from around the world. Biomaterials and nano-tribology receive special attention in this collection reflecting the general trends in the field. Further highlights include a focus on the new generation of instrumentation to probe wear at increasingly small scales. Approximately ninety communications and case studies, a popular format for the academic community have also been included, enabling the inclusion of the most up-to-date research. Over 200 peer-reviewed papers including hot topics such as biomaterials and nano-tribology Keeping you up-to-date with the latest research from leading experts Includes communications and case studies
Topics Include: industrial ergonomics, risk, accidents and accident prevention, safety and surveillance, posture perception, cognitive ergonomics, telerobotics, military occupational ergonomics, and international ergonomics.
Papers from a workshop held at Cornell University, Oct. 1989, and sponsored by Cornell's Mathematical Sciences Institute. Annotation copyright Book News, Inc. Portland, Or.
Advances in Research on the Strength and Fracture of Materials: Volume 4—Fracture and Society contains the proceedings of the Fourth International Conference on Fracture, held at the University of Waterloo, Canada, in June 1977. The papers review the social implications of fracture in a wide range of materials, with emphasis on education and politics. This volume is comprised of 22 chapters and opens by discussing fracture and fracture mechanics before introducing the reader to fracture problems in nuclear reactors; plastic flow around a crack under friction and combined stress; crack closure in fatigue crack growth; and the effect of the atomic structure's discreteness on cleavage crack extension in brittle materials. The following chapters explore the physical nature of fracture in composite materials; political and social decision making in relation to fracture, failure, risk analysis, and safe design; and the teaching of fracture in universities. This monograph will be a useful resource for metallurgists, materials scientists, and structural and mechanical engineers.
An experimental study was made to determine the quantitative accuracy of the hydraulic analogy when applied to subsonic internal flows such as exist in pure fluid elements. The analogy is based upon the correspondence between density and depth (or pressure and depth squared) when the Mach number and Froude number are equal. Experiments were run in air and in water on geometrically similar nonsymmetrical flow dividers. A factor was used to correct for the difference in apparent specific heat ratios k. (Apparent k = 2 for hydraulic flow, k = 1.4 for air flow.) After this correction was made, the data correlated to within three percent. The Reynolds number for the water flow varied from about 1...
