Extraction of surface texture data from low quality photographs to aid the construction of virtual reality models of archaeological sites
… which occur in three-dimensional models of photogrammetrically captured sites. Capturing the geometry of archaeological sites by photogrammetric means is relatively expensive and, because of the layouts typical of such sites, usually results in a degree of occlusion. Occlusions are filled …

Mapping Appalachia
The complexities of natural and human events that make up the history of a place also create components of its image. Images, even those that are meant to describe limited, specific information, often reveal more than that which they were designed to tell. The maps that have been used in …

Supervised manifold distance segmentation
… are involved. Both time and space complexity of this algorithm is O(N). With appropriate choice of feature vector, this method could produce similar qualitative and quantitative results to other algorithms like Level Sets and Random Walks. Analysis of sensitivity to parameters is presented. …

Plasmonics Using High Quality Epitaxial Graphene: An Approach towards Next-Generation Optical Computing
… noise tolerance. However, the diffraction limit of light prevents the shrinking of optical components to dimensions significantly smaller than the wavelength of light, typically µm's, compared to nm's for electronic devices. </p> <p> However, by adopting a plasmonic approach, which exploits near …

The effect of copper sulphate on froth stability
… process implemented in the recovery of valuable minerals from unwanted gangue material. Copper sulphate is used as an activator in the flotation of base metal sulphides (BMS) as it promotes interaction of collector molecules with the mineral surfaces. It is also used in certain …
