Determination of aggregate shapes using X-ray computed tomography and making virtual concrete

The shape of aggregates has significant effect on the concrete properties. To predict these properties with computational models the mathematically characterized shape has to be known. In the past, scientists assumed simple shapes like spheres and ellipsoids. To make models more realistic, aggregate shapes has to be also more realistic. X-ray...

Improving Quality of Electron Microscopic Images Using Post-Processing Filters

Electron microscopy makes it possible to magnify samples at almost atom level by using electron beams to scan the sample. These images could be improved in terms of noise and sharpness. In this research we looked into the possibilities to use post-processing filters for improving the quality of electron microscopic images.

Quantitative updating of land use information on 1:50,000 scale topographic maps using spot landsat thematic mapper imagery

This report gives the results of a study carried out in the Remote Sensing Department of the National Aerospace Laboratory (NLR) in The Netherlands concerning the updating of land use on topographic maps using remote sensing information. It was found that SPOT multispectral imagery is less suitable for land use classification purposes than...
