We discuss the use of homogenization techniques to derive approximate models with simple geometry for physical models of grids and trusses which h a v e a complex geometry that gives rise to computational diculties. Our presentation is in the context of inverse or parameter estimation problems for composite material structures with unknown characteristics(More)
Two experiments were conducted to test the hypothesis that animated representations of vector fields are more effective than common static representations even for steady flow. We compared four flow visualization methods: animated streamlets, animated orthogonal line segments (where short lines were elongated orthogonal to the flow direction but animated in(More)
The design and implementation of a compact and portable sample alignment system suitable for use at both synchrotron and free-electron laser (FEL) sources and its performance are described. The system provides the ability to quickly and reliably deliver large numbers of samples using the minimum amount of sample possible, through positioning of fixed target(More)
