We present a new finishing process that is capable of locally shaping and polishing optical surfaces of complex shapes. A fluid jet system is used to guide a premixed slurry at pressures less than 6 bars to the optical surface. We used a slurry comprising water and 10% #800 SiC abrasives (21.8 mum) to reduce the surface roughness of a BK7 sample from 350 to 25 nm rms and to vary the shape of a ...

Case histories of 263 incidents involving runaway reactions of the type A + B→ products, carried out in industrial batch reactors have been analysed on the basis of unit processes involved, initiating factors and type of industry. The case histories were drawn from Health and Safety Executive files, industrial records and the open literature. Although the data has no absolute statistical value,...

A predictive architecture is presented to react on sensor data in the case of high speed motion and low bandwidth sensor data. This concept is used for the vision based control of an industrial robot (KUKA) to track a contour at a speed of 1.6 m/s. The vision task can be performed very fast since only 2 rows of the image are analyzed. In this way an accuracy of 0.3 mm is reached in spite of unc...

A new series of silicon-containing derivatives of 2-aryl-3-(1H-1,2,4-triazol-1-yl)propanenitriles were synthesized and evaluated for fungicidal activities against rice sheath blight and powdery mildew on cucumber. These derivatives exhibited higher efficacy than reference fungicides.

Governments around the world are investing significant resources in the development of logistics clusters. This paper develops a methodology for identifying them and applies it to answer several lingering questions in the context of the US. It contributes to a more general debate in the general industrial clusters literature: while many authors see industrial clusters growing, others see them d...

The establishment of industrial ecosystem is the key to realize the economical sustainable development. This article analyses the related literatures of industry ecosystem, and points out the industry ecosystem's hierarchy. Then on the basis of theoretical analysis, the article proposes the building strategy of the industry ecosystem, from three aspects of the microcosmic, the intermediate and ...
