Analytical Challenges and Strategies in FE-EPMA
Unquestionably, since their introduction one decade ago, field emission (FE) electron microprobes have pushed the boundaries of electron probe microanalysis (EPMA) by offering new possibilities to characterize smaller features. As with conventional microprobes, the proper selection of the analytical conditions (beam energy, beam current, acquisition time, x-ray line) is essential to obtain an a...
متن کاملSpatial resolution and peak-pressure-change measurement accuracy
Background It has been suggested that plantar pressures should be measured at ~6.2 mm to accurately characterize local maxima [1], and it has been shown that sensor widths of 10 mm can cause a 30% pressure underestimation at the metatarsal heads [2]. However, these results assume that pressure maxima, not maxima changes, are of primary interest. The purpose of this study was to examine how spat...

متن کاملAccuracy of Digital Elevation Model According to Spatial Resolution
There are many kinds of DEM (Digital Elevation Model) generation methods such as a stereomatching from aerial photograph or satellite image, an interferometry from SAR data and an interpolation of topographic maps. On the other hand, we can use some accomplished DEMs. For example, NGDC NOAA offers global land one-km base elevation (GLOBE). And USGS offers Digital Chart of the World that has ele...
متن کاملCalibrating Large-area Mask Projection Stereolithography for Its Accuracy and Resolution Improvements
Solid freeform fabrication (SFF) processes based on mask image projection such as digital micro-mirror devices (DMD) have the potential to be fast and inexpensive. More and more research and commercial systems have been developed based on such digital devices. However, a digital light processing (DLP) projector based on DMD has limited resolution and certain image blurring. In order to use a DL...
