This title was first published in 2000: Steven Nivin analyzes a process vital to economic development - technological change. He furthers understanding of the processes driving innovation, so that we may gain a deeper insight into the development of economies. Specifically, the study explores the concept of innovation potential and the factors that result in variations in innovation potential across metropolitan areas, using the US machine tool industry as a case study. To provide a comparison, the same models are also estimated for the semiconductor industry. The findings indicate that urbanisation economies, localization economies, human capital, universities, and invention-derived knowledge are significant factors. The study assesses the contributions of three different skill levels of human capital; college-educated, graduate degree, and locally produced PhD's in mechanical and electrical engineering. Only the graduate and PhD degree measures are found to be significant, indicating the importance of having a highly skilled pool of labour within the region. The influences of the factors appear to be similar across industries, with some slight differences. The transfer of knowledge through patents is also studied. It is found that the transmission of this knowledge is slower between different industries, relative to the transmission within the same industry.

Sharpening workshop tools is probably the most diverse of all workshop activities and the one that is least understood by the majority of workshop owners. This is not unreasonable in view of the wide range of equipment suggested for the task, ranging from the complex, typically an industrial tool and cutter grinder, through to the humble off hand grinder. This book illustrates how most sharpening tasks can be carried out using an off hand grinder and a few simply made accessories, whilst doing this to a standard comparable to that achieved using much more sophisticated equipment. A lack of understanding of the processes almost certainly results in the workshop owner attempting tasks with far from perfect cutting tools that can diminish the satisfaction of a job well done. With the information in this book this situation can be avoided and working with blunt tooling should be a thing of the past.

The research areas as well as the knowledge gained for the practical use of robots are growing and expanding beyond manufacturing and industrial automation, making inroads in sectors such as health care and terrain sensing, as well as general assistive systems working in close interaction with humans. In a situation like this, it is necessary for future robot systems to become less stiff and more specialized by taking inspiration from the mechanical compliance and versatility found in natural materials and organisms. At present, a new discipline is emerging in this area, called "Soft Robotics". It particularly challenges the traditional thinking of engineers, as the confluence of technologies, ranging from new materials, sensors, actuators and production techniques to new design tools, will make it possible to create new systems whose structures are almost completely made of soft materials, which bring about entirely new functions and behaviors, similar in many ways to natural systems. These Proceedings focus on four main topics: * Soft Actuators and Control * Soft Interactions * Soft Robot Assistants: Potential and Challenges * Human-centered "Soft Robotics".

This book deals with wear and performance testing of thin solid film lubrication and hard coatings in an ultra-high vacuum (UHV), a process which enables rapid accumulation of stress cycles compared with testing in oil at atmospheric pressure. The authors' lucid and authoritative narrative broadens readers' understanding of the benefits of UHV testing: a cleaner, shorter test is achieved in high vacuum, disturbance rejection by the deposition controller may be optimized for maximum fatigue life of the coating using rolling contact fatigue testing (RCF) in a high vacuum, and RCF testing in UHV conditions enables a faster study of deposition control parameters. In short, Rolling Contact Fatigue in a Vacuum is an indispensable resource for researchers and engineers concerned with thin film deposition, solar flat panel manufacturing, physical vapor deposition, MEMS manufacturing (for lubrication of MEMS), tribology in a range of industries, and automotive and marine wear coatings for engines and transmissions.
