In this article, we explore the use of fluorescence spectroscopy to image growth patterns in the marine bivalve Arctica islandica (L.). The method presented here does not require any chemical treatment of the polished shell section and yields results comparable to acetate peels of acid-etched shell sections and Mutveitreated shell sections. Further, our results indicate that the annual growth l...
Grinding and polishing are widely used surface finish operations for a variety of precision and delicate component of ceramics, such as silicon wafers and gauges. However, the formation and evaluation of the subsurface damage induced have not been investigated, although subsurface damage is extremely important to the quality of the products. Grinding and polishing are usually carried out by a s...
This paper reviews a cyclic scheduling model of repetitive manufacturing environments consisting of exible machines and multi-stage jobs. We explicitly model two system performance measures, throughput and ow time, while incorporating variability arising from uncertainty in operation processing times. We present an iterative approximation scheme to estimate the two moment behavior of our perfor...
