Development of Ultra Precision Machining with High Positioning Resolution
INSTRUCTIONS The technology for ultra-precision machining has been developed rapidly and steadily. In recent years, the demand for free form, complex and microscopic cutting has increased as a result of the need for highvalue-added fabrication for items such as high NA glass lenses, micro-grooves, diffractive aspheric lenses and other optical components. The ultra-precision machine for cutting ...
متن کاملUltra-precision Machining Systems; an Enabling Technology for Perfect Surfaces
The technology of ultra-precision machining, spanning almost three decades, has only in recent years experienced major advances in machine design and, subsequently, performance and productivity. In the 1970’s, ultra-precision machining techniques were successfully adopted for the manufacture of computer memory discs used in hard drives, and also photoreceptor components used in many photocopier...
متن کاملLarge-scale Public Project
This paper examines dynamic voluntary contributions to a large-scale project. In equilibrium, contributions are influenced by the interplay of two opposing incentives. While agents prefer to free ride on others for contributions, they also prefer to encourage others to contribute by increasing their own. Main findings of the paper are that (1) agents increase their contributions as the project ...
متن کاملExploring the Architecture of Ultra Large Scale
An Ultra Large System is a system with no central control and composed of multiple interacting components solving a variety of different problems. Canonical examples are the internet or the US Electric grid. This talk will explore some of the characteristics of the architecture of such systems. We explore the architectural characteristics by examining the governance, the characteristics of Ultr...
متن کاملUltra-large-scale syntheses of monodisperse nanocrystals.
The development of nanocrystals has been intensively pursued, not only for their fundamental scientific interest, but also for many technological applications. The synthesis of monodisperse nanocrystals (size variation <5%) is of key importance, because the properties of these nanocrystals depend strongly on their dimensions. For example, the colour sharpness of semiconductor nanocrystal-based ...
